Purpose Materials supply is one of the important elements in construction operation and a major factor affecting the quality of construction projects. Many industries look to manage materials effectively by attempting to integrate logistics processes into logistics chains of suppliers and customers. Logistics processes, being crucial for successful completion of construction projects, but in fact, auxiliary, are often entrusted to external professionals specialised in logistic services, such as logistics centres. However, this tendency is yet to be developed in construction. The purpose of this paper is to develop a simulation framework for the examination of potential improvements of logistics performance using logistics centres. Design/methodology/approach A case study approach was adopted with computer simulation using Flexsim. Data of vehicle movements were collected during construction on-site from the start of construction to “hand-over” to the building owner. Findings The ideal location of a logistics centre is identified using vehicle movements data collected on the site. The potential improvements of the planned centre are then evaluated by simulating various scenarios of vehicle movements. The enclosed results from the simulations indicate that using a logistics centre will reduce waste for the construction project considered. Originality/value The paper emphasises that creating a logistics centre for a project can improve construction logistics performance, by consolidating and optimizing both off-site and on-site logistics, especially when the site condition is prohibitive (small footprint with limited loading bay area). Establishing logistics centres may help find ways of making the overall construction project more effective by improving the management of materials.

The goal of this article was twofold. The first objective was to investigate the diffusion and use of Project Management tools and techniques by manufacturing companies in an emerging economy, such as Argentina. The second objective was to assess the impact these instruments have on companies' financial and non-financial performance. The companies selected for the analysis have their registered office in the province of Buenos Aires. Overall, 172 manufacturing companies participated in the survey. The research used a quantitative analysis methodology, using a questionnaire for data collection. The influence of Project Management tools on the performance of companies (users and non-users) was assessed using a non-parametric approach. Regarding the first objective of the research, the results showed that SMEs use a limited set of Project management tools and techniques. However, most managers have shown a strong focus on such tools. About the second objective, the results highlight positive and statistically significant relationships between most PM tools and business performance, suggesting that PM users perform better than non-users. The results show that the scoreboard has a positive impact on the financial and non-financial results of manufacturing firms. Configuration management and cost estimation techniques result in the higher financial performance of user companies than non-user companies. Besides, users of integrated logistics support have significantly better financial and non-financial performance than other companies.Keywords: Project management, Performance, SME, Emerging EconomiesJEL Classifications: G32, M16, M21DOI: https://doi.org/10.32479/ijefi.11421

Integrated Logistics Support (ILS) is disciplined and unified management including activities in product life cycle management to create a product maintenance system (MS) to support the product throughout its intended life cycle at an acceptable cost. Along with information models combining product descriptions such as breakdowns, fault trees and methods of restorations, etc., mathematical models considered effective tools to get optimal results are proposed. The paper will present mathematical models, which play important roles in assessing and estimating material demand (spare parts), for the material supply management. These models are applied, in different levels of the ILS system, to the direct calculation of the material demands for scheduled and unscheduled maintenance

This paper studies how local non-oil Omani products could reach global markets by attracting local and international investors and improving the integrated logistics system in Oman. Therefore, the scope of this research is investment agencies in Oman, which are the Ministry of Commerce, Industry, and Investment Promotion and the Public Authority for Investment Promotion and Export Development. This study targets the leading logistics companies in Oman, such as Asyad Group. The study used an online survey and direct interview targeting specialists and experts in investment agencies and logistics companies. The results of the research showed that challenges are facing attracting local and international investors in local industries. Those challenges are the lengthy, complicated and costly procedures to obtain permits and licenses for investors, weak promotion of investment opportunities and local products at the international level, weakness of the local market, cumbersome regulations of the government, and so on. All these challenges constitute an obstacle to attracting investments. Findings also vindicate that weaknesses in logistical performance represented by the complex export and import procedures, complications in customs clearance operations, and the weak performance of land, sea, and air transport, which constitutes a barrier to exporting local products to global markets. The primary limitations that the researchers faced in conducting this research. First, there were many complications in collecting information through interviews. Some companies refused to conduct interviews due to preventive measures for the spread of the Coronavirus, which may affect the results.

This article investigated the comprehensive risk management model practised at SWIFT Integrated Logistics chemical storage operations. The objective is to systematically illustrate the risk factors by identifying risks and mitigating them from the flow of the operation. By reducing or containing the risk factors, we are able to provide a conducive, safe, secure working environment with initiatives toward zero-incident reporting cases. A qualitative research method was applied in this study. Respondents selected for this study were at the managerial level at SWIFT Integrated Logistics with experience working in warehouse operations for more than five years. SWIFT Integrated Logistics management wanted to diversify its warehouse customer's portfolio and accepted new business opportunities in chemicals warehouse storage. The move contributed greatly to the business strategy and finance, but they faced serious risk management issues, which resulted in six (6) incidents and raised the level of anxiety and concern among the warehouse team on health & safety issues. Future studies may look into additional strategies to implement a better warehouse risk management model or plan for a chemical warehouse. This study suggested that regular or continuous training should be provided to the staff. Basic first aid kit training is an example of the mandatory training that should be part of the job standard operating procedure. This paper contributes to the limited existing study on chemical warehouse operations. Experience and measures taken by SWIFT management may provide some ideas to improve the management of chemical warehouse for other warehouse operators. Although chemical warehouse operation safety is important, there is scarce academic research that explores this issue.

PurposeThe purpose of this study is to evaluate the after-sales strategy of an industrial equipment manufacturer.Design/methodology/approachThe research study’s object is the Brazilian operation of a company belonging to a multinational group that designs, manufactures and installs technology-based equipment. The research method is qualitative modeling with a quantitative analysis. A literature review and a focus group with managers organized the after-sales strategy of the company in four constructs measured by 24 indicators. The constructs are technical assistance (TA), reliability management (RM), customer relationships (CRs) and spare part logistics (SL).

The study proposed four strategic actions that change the type of emphasis that the company poses to service: from in-house to field maintenance service, from correction to prevention reliability improvement, from technical- to customer-focused relationships and from direct to integrated logistics service.Research limitations/implicationsThe study limits to the case of a technology-based manufacturing company.Practical implicationsThe strategic movement reallocates resources from leading indicators to lagging indicators in a sharp, clear movement of forces in the company.Originality/valueThe main contribution is a structured method to evaluate and control the strategic performance of an industrial equipment manufacturer in after-sales activities.

The problem of developing an effective system for controlling the condition of electrical equipment in the conditions of the transformation of the modern electric power industry is investigated. The classification of approaches to the equipment condition control depending on the degree of using the available information is presented. An option of forming the equipment condition control function based on “flexible” strategies and nondestructive testing technology is proposed. The conceptual model developed describes the principles of structural and functional interaction of procedures for controlling the equipment’s key technical parameters, the predictive diagnostics of its condition, and the assessment and planning of its subsequent operation within the framework of procedures of integrated logistics support over the short or long term. The scenarios of developing criteria for making control decisions during operation of electrotechnical equipment based on the results of nondestructive testing taking into account the actual category of its condition and the requirements of regulatory and technical documentation are considered. An example of using this approach at oil extraction facilities is given. The development of the proposed conceptual solutions is considered as a possibility to improve the technical and economic efficiency of the equipment operation procedures, including the construction of new-generation electric power grids.

The problem of foreign-made spare parts and components import delivery is relevant because international cooperation in aviation industry has become widespread. Logistics provides not only new components procurement but also borrowing, renting, leasing or exchange operations. To control the process effectively, it is necessary to decompose the import delivery process, as effective integrated logistics provides spare parts and components delivery within the shortest time and the lowest costs. Project management methods are used for this purpose. The object of the research is import delivery of foreign-made spare parts and components to maintenance and repair center. For the shortest delivery time and the lowest delivery costs it is necessary to describe the import delivery structure, to determine the import delivery works interrelations and their duration and to standardize implementation costs. The research describes the foreign-made spare parts and components import delivery structure, explains the operations sequence, sets the approximate work duration. The import delivery network schedule was also made. Implementation of the resulting structure in project management software will allow to control import delivery time and costs, to make out reports on resource usage. The import delivery project passport will help to manage the resources costs, used for spare parts and components delivery as well as to optimize the project.

Aim. To analyze and summarize the existing scientific approaches and mechanisms for innovation management when developing and registering medicines for the treatment of coronavirus disease (COVID-19) based on the implementation of a logistic approach and the creation of the integrated logistics innovation and information system.Materials and methods. Databases of the Internet, such as PubMed, the Food and Drug Administration, the European Medicines Agency were used. The retrospective, logical, and graphical methods of research, as well as the content analysis were applied. Results. In order to overcome the current therapeutic crisis in the world, 2 strategies are used: repurposing of the existing drugs (favipiravir, tocilizumab, etc.) and development of candidates for drugs with a direct targeted mechanism of action against COVID-19 (remdesivir, vaccines, etc.). Traditional approaches to the innovative process of activity as a closed one, oriented to the internal environment of the innovation system become ineffective. For this purpose, it is promising to apply a logistic approach to innovation management in the development and registration of medicines for the treatment of coronavirus disease (COVID-19). In the conditions of open innovation processes, those organizations and countries that can quickly implement an innovative idea gain a competitive advantage. It is necessary to manage innovation processes so that when an innovative idea enters the first stage, the idea is transformed into the final product with the shortest possible time. Logistization of innovation activities involves continuous improvement and optimization of the existing processes, allows you to organize innovation processes as a through integrated flow, reduce the time and costs for the implementation of innovative projects, gain benefits by optimizing innovative information, material and other flows.Conclusions. The result of the logistics of innovation in pharmacy will be: the creation of a complete cycle – from scientific research in scientific institutions, universities, pharmaceutical companies to the development of the production of innovative drugs; optimizing the use of resources associated with the implementation of innovative projects, as well as reducing the duration of the implementation of these projects; creation of a modern innovative infrastructure in the industry; wider attraction of investments in RD use of R&D results in training specialists.

The development of the scientific concept of the economic category “logistics of trade services”dictates the need for the formation of logistics systems of trade services, which should be based on two dominantcomponents - this is the territorial component and the integral. The need to include a territorial component isexplained by the fact that retail trade and public catering, working for a specific consumer, gravitate towards theplaces where their client is located. The second component, an integrated logistics tool, provides for a significantchange in the objective function and the criteria for the optimality of logistics activities, which makes it possible toachieve maximum competitive advantages to ensure the implementation of development strategies of the tradingindustry as a whole. In times of progressive digital transformation and constant change, a continuous reorientation ofstationary retail is indispensable in order to be successful in the future. The practical recommendations for actionprovide a guideline for the transformation of stationary retailing based on digital change processes. Various factorsare taken into account, which is identified as critical success factors for stationary retail. These include areorientation of the business model, the introduction of new digital technologies and data protection. In general,stationary retail must rethink the business model holistically and be open to radical innovations in order to besuccessful in the long term.

We analyze the integrated logistics network design and inventory stocking problem in service parts logistics, where each customer requires a certain response time-based service level. We introduce a non-linear mixed integer optimization model that explicitly captures the interdependency between network design (locating facilities, and allocating customers’ demands to facilities) and inventory stocking decisions (stock levels and their corresponding stochastic fill rates). We then provide two different linearized mixed integer formulations for this problem that can solve small and medium size problems. We show that it is still a challenging problem in general, for which we have a Lagrangian-relaxation based approach that provides extremely tight lower and upper bounds. Our extensive computational study shows the effectiveness of the proposed approach for a variety of problem instances, producing provably near-optimal integrated solutions.

The article is devoted to the research of modern tendencies of defining the essence of supply chain management as an innovative philosophy of spiral business dynamics. The research is based on the generalization and application of the basic principles of wave theory of development, classical theory of marketing, modern provisions of the theory of TQM and conceptual provisions of the theory of spiral dynamics. A new look at supply chain architecture, from identifying growing needs for specific products and ending with utilization, namely the emergence of new links in the chain of transformation of resources such as the stage of intelligent innovation processes to create modifications and upgrades or design a new product to meet growing needs. A multicomponent process of change is considered in view of current trends. The application of the theory of the spiral dynamics of the supply chains is a logical and predictable extrapolation of the general tendencies of the development of the life support system and the growing needs of society, starting from the “subsistence economy” and to the creation of modern global economic associations such as transnational corporations and international transport corridors. economic associations of countries and international programs of scientific search in the field of artificial intelligence and development of the cosmos.

Truck flow plays a vital role in urban traffic congestion and has a significant influence on cities. In this study, we develop a novel model for solving regional logistics network (RLN) design problems considering the traffic status of the background transportation network. The models determine not only the facility location, initial distribution planning, roadway construction, and expansion decisions but also offer an optimal solution to the logistics network service level and truck-type selections. We first analyze the relationship between the urban transportation network and the RLN design problem using real truck data and traffic flow status in a typical city. Then, we develop the uncover degree function (UDF), which reflects the service degree of the RLN and formulates based on an impedance function. Subsequently, the integrated logistics network design models are proposed. We model the RLN design problem as a minimal cost problem and design double-layer Lagrangian relaxation heuristics algorithms to solve the model problems. Through experiments with data from the six-node problem and Sioux-Falls network, the effectiveness of the models and algorithms is verified. This study contributes to the planning of regional logistics networks while mitigating traffic congestion caused by truck flow.

A framework for the algorithm-based CL platform is established, based on which, the operational mode of it is described in detail. An integrated logistics task assignment model is built to optimally match logistics service resources and task of large scale in the algorithm-based CL. Particularly, an improved grasshopper optimization-based bitarget optimization algorithm (GROBO) is proposed to solve the biobjective programming model for service matching in CL. The case of Linyi small commodity logistics is taken as an application. Simulation results show that the proposed GROBO provides better solutions regarding to searching efficiency and stability in solving the model.

In today’s economic context most supply chains are global and complex. Therefore integrating different transportation modes have become crucial for achieving cost and time savings in most supply chain systems. This paper presents a framework for evaluating the potential for implementing air-maritime integration. First we identified ten most influencing factors to establish a air-maritime integrated logistics hub using expert opinion and literature. Meanwhile two methods of integration, substitution and complementary were identified. AHP analysis was used to derive important weights to influencing factors and to determine the best method of integration. Finally IPA analysis was used to identify relative importance and current performance of individual factors and to classify them to four quadrants. Future actions required for implementing air-maritime integrated logistics were discussed based on the IPA classification. The framework was applied to assess the air-maritime integration potential of Sri Lanka. As per the results of the analysis, the best suited method for Sri Lanka was found to be the complementary method. Results also suggested that worldwide connectivity and centralized location are the most important criteria for implementing integrated logistics. By further improving the analysis procedure, this can be used for any other scenario in the world for evaluating the potential for air-sea integration.

Introduction/purpose:The paper presents the development of logistics as a specific field of military branch, a contemporary field of business and a scientific discipline which inspires many researchers, theorists and practitioners to approach logistical problems from various aspects. The essence of logistics is an integrated approach to all its constituent activities, which reduces costs and increases the efficiency and effectiveness of the logistics system in supporting the primary activities of an organization or a technical system. Due to intensive and multidimensional development of logistics and its applications in various fields, the need for highly educated logistics personnel with specialized knowledge for performing a wide range of activities in the logistics system is becoming increasingly necessary. Methods: Based on the description of military, business, national and humanitarian logistics and a comparative analysis, their mutual relationship is shown. Results: Based on the performed analysis, an explanation of the importance of studying logistics as a multidisciplinary science and pointing out the need for specific training of logistics personnel was given. Conclusion: Logistics is intensively developing in various fields depending on the goals of the system (organizational and technical) it supports. In general, commercial logistics is evolving faster than military logistics, and many innovative commercial logistics solutions are being deployed in military logistics. However, certain solutions that produce good results in the commercial sector do not produce adequate results in the military. Therefore, it is necessary to carry out research and study of the functioning of logistics systems in different fields and carefully integrate individual solutions into the military logistics system. As the most complex logistics system, military logistics requires specific staffing and training of logistics professionals.

Increased trends towards servitization within previously exclusively manufacturing industries makes a larger part of maintenance become the responsibility of the manufacturer. This increased responsibility makes it more important for suppliers to know how different parameters contribute to cost, to be able to price their contracts correctly. Systems Engineering (SE) and Integrated Logistics Support (ILS) are two current methodologies on how to manage large systems. These methodologies are mainly used within defence industries and large capital-intensive infrastructure projects but are today also utilised in civilian industries. With the new methodology of Model Based Systems Engineering (MBSE) and the new demands of servitization it becomes more important to know how different parameters affect the final cost of a project during the very early phases of development. Within ILS the parameters Administrative Delay Time (ADT) and Logistics Delay Time (LDT) have previously not received attention proportional to their contribution to overall availability in projects. This thesis is based in literature, interviews of industry professionals, and the study of a real case of an electrical charging infrastructure project currently in development. From these sources multiple paths to resolve the issues with support from ILS, MBSE, SE, and other management literature are explored. Several attributes of the case, and characteristics of MBSE and ILS leads to the conclusion that coupling the methodologies with Lean methods would lead to better insight into where critical points in the explored system are and give ways of resolving issues with ADT and LDT that exist. The combination of MBSE and Lean methods could successfully identify possible critical points in the error handling of the electrical charging infrastructure system early in the process of implementation. Conclusionary the combination of MBSE, ILS, and Lean is a possibly powerful way to identify and improve the availability and consequently the cost of a project in the early stages. Tjänstefiering är en trend som gör att en allt större del av underhåll inom tidigare endast tillverkande industrier blir tillverkarens ansvar. När detta ansvar ökar blir det viktigare för tillverkaren and veta vilka parametrar som är kostnadsdrivande. Detta för att kunna prissätta sina tjänster korrekt. Systemteknik (SE) och Integrerat Logistikstöd (ILS) är två metodologier som används till att hantera underhåll av stora system. Dessa nyttjas främst inom försvarsindustrin och inom kapitalintensiva infrastrukturprojekt, men används även i privat industri. Med hjälp av en utveckling inom SE, Modellbaserad Systemteknik (MBSE), och med de krav som tjänstefiering innebär så blir vikten av att ha korrekt angivna parametrar tidigt i projektet mer tydlig. Inom ILS är särskilt parametrarna administrativ väntetid (ADT) och logistisk väntetid (LDT) särskilt eftersatta med hänsyn till hur mycket de påverkar tillgängligheten och kostnaderna för systemet. Detta examensarbete baseras på tillgänglig litteratur inom nämnda områden, intervjuer med industrirepresentanter, och dokumentation och intervjuer i ett riktigt fall. Det riktiga fallet är ett pågående projekt för uppbyggnad och underhåll av laddningsinfrastruktur för eldrivna fordon. Från dessa källor utforskades och analyserades flera vägar för hur man skulle kunna förbättra hanteringen av ADT och LDT med grund i litteraturen kring ILS, MBSE, och SE med annan litteratur inom mangament som stöd. Fallets egenskaper, och egenskaper hos ILS och MBSE leder till slutsatsen att en kombination av MBSE och Lean skulle leda till att man lättare kan utforska kritiska delar av ett underhållssystem, och åtgärda existerande problem med ADT och LDT. En kombination av dessa principer kunde identifiera kritiska punkter i felhanteringssystemet hos laddarna i infrastrukturprojektet trots att projektet befann sig tidigt i implementationen. Slutligen kan konstateras att MBSE, ILS och Lean är en möjlig kraftfull kombination för att förbättra tillgängligheten tidigt i ett projekts livscykel.

Integrated logistics support (ILS) and asset management (AM) are two concepts associated with the life cycle of a physical asset. Each of them has an objective of optimising the life cycle cost in order to maximise return on investment. However, the integration of ILS with AM may lead to improved optimisation of the life cycle cost based on the concept of synergy. The aim of this paper is to investigate how ILS and AM can be integrated and whether the resulting framework has the potential for improving physical AM. This bridge of familiar concepts is expected to support practitioners and academics in understanding a holistic framework for managing the life cycle of assets. In the academia, it can support the teaching of life cycle management. This paper builds on a study of relevant literature to realise a generic integrated logistics support and asset management (ILSAM) framework. The ILSAM framework is adapted to infrastructure assets by adapting its ILS component based on additional literature study and experience in relation to a large-scale railway project. This adaptation shows a potential for improved quality management, which plays a vital role in enhancing safety.

The distribution/allocation problem is known as one of the most comprehensive strategic decision. In real-world cases, it is impossible to solve a distribution/allocation problem in traditional ways with acceptable time. Hence researchers develop efficient non-traditional techniques for the large-term operation of the whole supply chain. These techniques provide near optimal solutions particularly for large-scale test problems. This paper presents an integrated supply chain model which is flexible in the delivery path. As the solution methodology, we apply a memetic algorithm with a neighborhood search mechanism and novelty in population presentation method called “extended random path direct encoding method.” To illustrate the performance of the proposed memetic algorithm, LINGO optimization software serves as comparison basis for small size problems. In large-size cases that we are dealing with in real world, a classical genetic algorithm as the second metaheuristic algorithm is considered to compare the results and show the efficiency of the memetic algorithm.

Intelligent perception network, suitable for the interconnection and integration of material distribution information equipment in product assembly workshops, information sharing between equipment, and data interaction between equipment and servers. The areas involved include automated material distribution, integrated logistics operation management and control, digital measurement and intelligent control. This article first describes the proposed intelligent perception network and the existing material distribution methods, analyzes the realization of intelligent perception networks of different architectures, and then proposes a set of material distribution methods for the particularity of logistics distribution in the aviation workshop. The method is driven by the process flow, and conducts dynamic and refined management of the entire process of material storage, storage, transfer, and inventory, and real-time monitoring of the type, quantity, and status of materials through intelligent terminal equipment, handheld terminals and NFC communication equipment, Storage location and other specific information; secondly, with the goal of minimizing delivery time and delivery cost, according to the material requirements of each station of the production line, the convolutional neural network method is used to design the optimal material distribution plan. Finally, build a software and hardware platform and realize the operation of the convolutional neural network on embedded devices to complete the entire workshop material distribution process.

In recent years many companies shift from product-based to service-based business models. This includes aerospace and defense industries. This new trend of servitization moves the risk of system downtime and higher servicing costs from customers to contractors and increases the need for more precise estimations on in-service support of systems. The fundamentals of in-service support (ISS) planning is not a new concept. Aerospace and defense has set foundations with the introduction of Integrated Logistics Support (ILS), a discipline within Systems Engineering, in the 1960s. Nowadays, ILS (also Supportability Engineering or Logistics Engineering) anticipates servitization and other trends by transforming into Integrated Product Support (IPS). Decisions for ISS in utilization are taken in the early system life cycle phases. Uncertainty in these phases has a negative effect and represents a threat to ILS and system performance in utilization. The use of reliable measures for ILS is needed in early life cycle. However, no ILS specific measures for early life cycle phases have been established. Instead, system measures for reliability, maintainability, availability, affordability (or life cycle costing), etc. are also used for measuring ILS performance. Unfortunately, it is not documented if established system measures work for ILS. This paper is addressing the issue. Established system measures were qualitatively reviewed for their applicability in ILS in early life cycle phases and utilization. Found weaknesses are described. As a result, the need for ILS specific measures is identified.

Each logistics information system has its own storage. This is due to the fact that the companies that form the supply chain are independent and may have different legal statuses, legal documents, etc. But in order to ensure the smooth and adequate operation of the platform when making decisions, it is necessary that the data and applications of one system be recognizable in another system. Therefore, integration is needed at several levels. The main goal of the study is to showpossible ways of creating integrations starting from the system design stage. Integration theory is a complex task, so it needs to be comprehensively considered. All integration processes are reduced to data integration and software integration. The analysis of integration methods is carried out, as well as factors that negatively affect the integration possibilities are considered. Solutions of integration problems, to ensure the optimization of the design process (reduction of the design time) and design of the system itself (minimization of the content of the system), and during the operation of systems, optimization of its functioning (behavior) of the system. As a result of the study, the need to create data integration and application integration that allows you to structure data is shown. It should be noted that data can be located at all levels of the system architecture. And the system software can be: software modules, applications and systems. The basis of all types of system software, i.e. applications and an integral system are made up of software modules, design and development of software (i.e. based on programming systems) is based on service-oriented technologies, where the basis of systems is software services. The research carried out can be used in the development of information systems. Keywords: information system, platform, integration, services, data.
