This study presents the development of an upgrading program for a supermarket-type warehouse that supports the supply of goods in a manufacturing company located in northwestern Mexico. The tool Kanban is applied to achieve and improve the redistribution, reorganization, and identification of replenishment points for the production process. A five-step methodology is followed and 70 materials are selected to update their storage and inventory levels on the warehouse management system. The results show an increase of 33.53% on overall delivery metric compliance and a 5.49% increment on supermarket maximization. It is concluded that upgrading the warehouse management system improves the efficiency of materials supply since it increments successful on-time delivery objetives and since it increments the supermarket's share on supply.

The research had the objective of making a characterization of the architecture of the Modern Movement of the former province of Las Villas (1946-1960), little studied to date. Files from the College of Architects, archival documents and periodicals were consulted to formulate working hypotheses. The most significant works, which make up the study sample, were corroborated in field work. The characterization includes the themes, authors and periods of greatest production. It delves into housing, according to predominant typologies, and in warehouses and shops, exponents of an incipient industrial architecture. Works of a singular nature that respond to different programs are also defined. Housing was the most relevant architectural theme of the period, accompanied by an important volume of industrial and commercial works, and other public buildings. The works were executed with state investment, or with private capital, mainly by local architects, affiliated with the College of Architects of Las Villas. [ABSTRACT FROM AUTHOR]

Six functional traits of the stem and leaves of species with basal diameters greater than or equal to 5 cm were measured in eight permanent plots with successional shrub coverings, in the Eastern Cordillera of Colombia, in order to describe the functional traits of the species. For each trait, distribution frequencies and correlations were obtained, and used to determine acquisitive and conservative strategies. Most of the 45 species recorded had small leaves, low specific leaf area, low maximum photosyntetic assimilation and low maximum height; wood density was centered on the median of the distribution. There was no correlation among leaf traits, wood density and maximum height,. Nine species had acquisitive traits, with high rates of maximum photosyntetic assimilation, high specific leaf area, low leaf dry matter content, and low wood density. On the contrary, 36 species with conservative traits, showed low rates of maximum photosyntetic assimilation, low specific leaf area, high leaf dry matter content and average wood density.

Adding a new sales channel creates new challenges in terms of inventory management due to the difference in order size and fulfillment times as well as the uncertainty in the demand of both channels. The objective is to design a mixed inventory management model composed of a joint replenishment model for the traditional retail channel and a continuous review model for the Online channel, both with stochastic demand, due to the difference they present in their operational management. A heuristic method was developed to solve the problem and for its validation numerical examples were evaluated where an 11% reduction was found in the cost of the dual channel warehouse inventory policy with the proposed model which seeks to represent an approximation of management such as joint replenishment at retailers.

The specialty coffees of the Department of Nariño have been recognized worldwide for their excellent quality, but they have been affected by the inadequate handling of the product in its supply chain, specifically in the areas where it is stored, directly affecting its differential attributes, therefore which presents an approach to solve the problem of selection and location of possible potential areas, for the establishment of a distribution center, essential for its entire chain. In the present study, a decision-making approach with multiple criteria (MCDA) was applied, specifically the analytical hierarchy process (AHP) and weighted linear combination (WLC), with the incorporation of geographical criteria and their implementation in GIS (Geographical Information Systems), where 38 possible alternatives (Producing Municipalities) were evaluated for the establishment of a distribution center, using criteria previously identified with the help of experts in the areas of location, logistics, connectivity and specialty coffees, where those selected were: production Municipal, road connectivity and average temperatures. As results, maps of normalized and weighted criteria were generated according to the qualification or level of importance given by the experts through the model (AHP) and later using the weighted linear combination method (WLC) and GIS, the possible ideal areas were identified for the establishment of the distribution center. In conclusion, we can affirm that as the number of criteria increases, it implies greater complexity for decision-making, being of great help the implementation of technological tools such as GIS for the analysis and management of information in the resolution of this type of problems, which in the specific case of this project brought us closer to having a departmental overview of the possible ideal areas to establish a distribution center for specialty coffees. In detail, the methods and criteria used, data sets used, results obtained and discussion, finally the most significant conclusions, are described. [ABSTRACT FROM AUTHOR]

The present study aims to minimize the total distance traveled by a postal service company with two distribution centers by applying the p-median algorithm to a group of customers with the closest origin while solving vehicle routing problems. The routes followed by the company are empirical and start from a single depot. First, the nearest neighbor heuristic approach is applied to determine an initial solution. Then, the computational tool Excel Solver is used to generate a second solution for a single origin by applying the p-median algorithm, which resulted in a couple of additional total distances. The results show an improvement of 20% by the pmedian in comparison to the nearest neighbor approach. The p-median is also four percent lower than Excel Solver. It is concluded that the p-median algorithm successfully reduces total distances. [ABSTRACT FROM AUTHOR]

How to rehabilitate an industrial warehouse as a family home? Can the new spaces identify their occupants? These are some of the motivations that led to interviewing the architect Carol Iborra Pérez, author and executor of the rehabilitation of an industrial warehouse into a family home, known as Casa Nau (Poble Nou, Barcelona, 1999). A guided tour is made by the designer herself, through the ample and unique space of the house, in which the different areas with appropriate interior solutions are distinguished. It shows how it is possible to make good architecture from a built space whose “obsolescence” pointed to its disappearance, rescuing and giving a second chance not only to the property, but also to the neighborhood where it is located.

Real estate financialisation in Mexico is moving towards a process of increasing securitization based on investment instruments that entered the stock market. One of them is the Real Estate Investment Trusts (REIT, known in Mexico as FIBRAS), which group income-generating properties from the productive sector: offices, shopping centers, hotels, industrial buildings, among others. This paper examines the participation of this instrument in the financialized urbanization process through the analysis of its property portfolios and their diffusion in the urban system. The results show a process of specialization and diversification of the trusts; Its spatial logic reveals uneven patterns, with a greater presence of commercial properties and specialized services in the main metropolitan areas, while industrial and logistics warehouses were located in rural areas and the peripheries of urban centers that operate as nodes of the chains global value of manufacturing sectors. The expansion of properties in the Metropolitan Area of the Valley of Mexico reflect the role that this instrument plays in the consolidation of service-oriented enclaves. [ABSTRACT FROM AUTHOR]

Light roofs, especially those made of asbestos-cement have been widely used in Cuba. Their use includes a wide range of building types, such as industrial facilities, warehouses, temporary facilities and that which is the focus of this paper: the one-story single-family home.

This study aims to minimize the total traveled distance for the picker routing problem (PRP) by assessing 2D multi-block warehouses. The PRP is responsible for planning tours to visit different storage positions to satisfy the requirements of each customer order. Therefore, the minimum distances between each pair of storage locations to visit on a tour are formulated. An ant colony optimization (ACO) algorithm is proposed and adjusted to improve performance. Based on computational experiments, it is established that the proposed ACO provides high-quality solutions. It also generates satisfactory savings when compared to a metaheuristic and to two widely used heuristics, requiring viable computing times for simulation environments and real warehouse operation environments. It is concluded that the proposed ACO algorithm for PRPs provides high-quality solutions within reasonable computational time. [ABSTRACT FROM AUTHOR]

The objective of this study was to determine the predominance between Zabrotes subfasciatus (Boheman) and Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae) on common beans in field and storage conditions. Two experiments were carried out: one with samples from warehouses where there were beans infested by weevils and the second with pods of three bean cultivars taken in the field every seven days for 28 days, starting from the physiological maturity. The samples were taken to the laboratory and kept under controlled temperature, humidity, and luminosity, in a completely randomized design. Frequency analyses were performed to find out the predominant species, and the average density of insects were compared by analysis of variance with Tukey's test (p≥0.05) The frequency analysis indicated the presence of both species in storage conditions, but Z. subfasciatus predominated with 94.73 %, in addition to showing greater infestation. Under field conditions, the presence of Z. subfasciatus was not detected. The presence of A. obtectus under field conditions was low and apparently linked to the degree of maturity of the different bean cultivars. [ABSTRACT FROM AUTHOR]

This research study proposes a classification system to identify and prevent occupational accidents in fiber storage warehouses at a pulp and paper facility. The present analysis is based on variables including pedestrian circulation, bobcat, trailer trucks, access, pedestrian circulation zones, and handrails. The proposed methodology defines and trains the system by using occupational accident event data collected at the facility. Three different predicting algorithms are used: J48 decision-making trees, Naive Bayes, and Bayesian nets. The results show that the J48 decision-making tree algorithm accurately identifies possible occupational accidents 90% of the time. It is concluded that identifying variables involved in occupational accidents allows generating a C4.5 (J48) decision-making tree that can be used as a support tool to prevent occupational accidents.

Inventory control has become one of the most worked topics in the academy in collaboration with the industry due to the high representation of product storage costs and the costs associated with lost sales due to not having product availability at the time of demand. This article presents a proposal for the inventory control problem of the most representative items of a spare parts warehouse, where more than one criterion must be considered. The methodology applied was initially based on the realization of a classification of the items through the use of diffuse AHP (FAHP), where important criteria related to the characterization of the type of items, such as total cost and criticality, were taken into account. with this, the most representative groups of items were identified, then a second classification was made to identify within these groups the critical articles for the control system. Subsequently, a demand analysis and the respective forecast for the items classified as type A were carried out. Finally, the proposal for the application of the continuous inventory control policy (s, Q) is presented, taking into account the analysis of the policies used for the spare parts and is validated by a case applied to a sugar mill. Among the main results of the investigation is the identification of those most important references for the mill considering multiple criteria, allowing to establish an inventory policy that minimizes the cost and meets a level of service previously defined by the organization.

The objective of this paper is to establish what are the critical factors for the spatial design of distribution centers, specially inmotic storage ships. To do so, the principles of the adjusted general methodology (MGA) were used along with the implementation of experimental design (DOE) in the context of a faucet production company in Bogotá, Colombia. The MGA methodology lays its foundations in the application to industrial real estate projects, in a supply network scheme. Furthermore, DOE is used as a way of obtaining an optimal alternative which satisfies the expectations of the company and its clients from an economic and statistical point of view. The results show that the storage capacity of the centralized distribution center is the most significant factor in the design stage, being an essential factor for rationalizing investment in working capital and for maximizing the benefits of the company.

This paper presents a particular case of the facility location problem. The characteristic of this problem is that it contains a set of clusters or nodes that represent the accumulation of clients who demand a single product. It is desired to locate P distribution centers (DC) where the demand of clusters is only satisfied if we located a distribution center in this cluster. Moreover, the number of capacitated plants and its location must be determined in order to supply the different distributions centers. The objective is to maximize the utility by considering, in one hand, the incomes that are obtained for satisfying the demand of different clusters and in the other hand, the installation costs incurred when locating the Distribution Centers and the plants as well as the costs of material transport from the plants to the distribution center. Other applications of this problem are appreciated in telecommunications networks, electrical networks, etc. The paper also present a new model of integer programming that allows to solve small instances, up to 300 clusters, in an acceptable CPU time, the problems were programmed with AMPL and solved with CPLEX 11.0. For two larger instances the authors present heuristics, which allow obtaining solutions with a GAP least than 1%. [ABSTRACT FROM AUTHOR]

This paper proposes the incorporation of data envelopment analysis (DEA) to the methodology for the construction of a sustainable adjustable inmotic storage hall (MEINASA in spanish), in order to make it more robust for application in the design of production systems for warehousing of non-perishable products, given the interests of the client and the buyer-supplier echelon in the supply networks. MEINASA is used in a real design case of a distribution center for a manufacturer of faucets and DEA is applied to calculate the efficiency index of the 16 generated proposals, obtaining five efficient designs which can be assigned as peers for improvement of the remaining ones. The results suggest possible modifications that can be made on the designs identified as inefficient. [ABSTRACT FROM AUTHOR]

Objective: The aim of our study was to investigate the species and breeding density of acaroid mites in stored products in China. Methods: We tentatively harvested the samples from the products stored in warehouses, commercial stores and civilian houses, and the products. Results: The results suggested the mites varied a lot in species regarding their ecological habitus and habitat. Still, the breeding density in different samples was associated with the sampling conditions. Conclusions: These discrepancies may be associated with the samples collected in diverse environment for the mites, and the findings easily suggest that acaroid mites are in universal distribution.

This paper presents a combined methodology based on multicriteria decision analysis and optimization for the distribution centers location problem. The initial approach consists of a set of relevant quantitative and qualitative attributes used for the decision of locating distribution centers. From quantitative criteria a multi-objective mathematical programming model to minimize costs is proposed. This model provides alternative solutions that may be compared to the other ones initially known. These solutions are assessed for a multicriteria decision model which incorporates qualitative considerations of the problem that are infeasible to represent algebraically. Therefore, the application of the multi-criteria decision analysis model evaluates a set of feasible solutions to suggest for the best alternative considering several attributes.

Stability and development of companies depend critically on the ability to satisfy customers with the maximum efficiency and reliability. They must manage to work with minimum inventories and growing service levels. This paper shows the application of a procedure that uses quantitative tools for determining the behavior of demands and the order size that should be made by the main warehouse of a restaurant that offers local and international food. This restaurant presents an annual loss of 2039.73 CUC for the concept of losses due to ignorance about the use of quantitative tools for making decisions about inventory management. The application of the procedure for three weeks led to an increase of the total profits of 696.54 CUC and a decrease in the total cost of 630.62 CUC. [ABSTRACT FROM AUTHOR]

The evaluation of logistics processes and supply chain by ergonomics discipline is unusual in Cuban business practice. The organic sugar storage in sugar factory "Carlos Baliño" is one of the most important processes in the manufacture and marketing of the product, for that reason we decided to conduct this study combining two disciplines: Logistics and Ergonomics. The objective was to determine the ergonomic demand generated from the analysis of the work system in organic sugar storage and their integration in one or more ergonomic demands. The methods used in this study are: the unstructured interview, review and analysis of official documents, the Delphi methodology, application checklists, analysis of indicators, surveys, and group work techniques. The application of the methodology generates two integrated ergonomic demands on the consensus of consultants, experts and direction of the enterprise. The work demonstrates the need of deep in macroergonomic diagnostics as a specific technique of the work system analysis where storage is developed. In turn, allows tracing the strategy for the development of ergonomic intervention programs in this process. [ABSTRACT FROM AUTHOR]

This paper presents the development of an autonomous robot for stock handling in warehouses using radiofrequency identification (RFID). Because of the complexity of handling inventories and locating products in large warehousing areas, it was developed a prototype of an autonomous robot for the identification and handling of products and inventory real time updates. The prototype emulates a forklift and is capable of performing autonomous tasks that demand an inventory, carrying loads over a pound on a marked track following a black line with bifurcations. Using RFID technology the forklift is able to read and write data on the products in a label ant then to download this information on a pc through an inventory control software. The experiments showed the convenience of RFID technology for safe product marking because of its flexibility and low cost and the usefulness of line following navigation in structured environments.

In this document we present different aspects that are necessary to perform an excellent administration and control of distribution centers that corporations may have. If these ideas are implemented correctly in an efficient way, most of the productivity problems in the warehouse could be solved easily. Thus, it is important to evaluate the products' activity profile, the layout of the warehouse and the products' flow through the distribution center. The objective of this process is to obtain the conditions of a world class warehouse. [ABSTRACT FROM AUTHOR]

This paper considers the three-echelon uncapacitated facility location problem (TUFLP), which consists on both defining the flow of products from manufacturing plants to clients via a set of warehouses and the location of such warehouses. The objective function is to minimize the total cost of warehouse location and production and distribution. Since the problem is NP-hard, this paper proposes a Greedy Randomized Search Procedure (GRASP) to solve the single-item case. Computational experiments are conducted using known instances from the literature. Results show that the proposed algorithm performs well obtaining very good solutions (and even optimal values) in less computational time than an exact method based on mixed-integer linear programming.

In the databases field, several methods have been proposed for the generation of the logical design of a data warehouse, on the other hand there are also studies that allow the storage and operation of fuzzy data in relational databases. This paper presents a methodological proposal with an MDA approach. which allows to generate the logical design of a fuzzy DW. The technique was used to identify the basic elements of multidimensional modeling and extends them to manage fuzzy attributes in the measures at a conceptual level, through the application of a sequence of transformations to avoid the generation of a logical fuzzy multidimensional design. A key element for this process is the extension of the CWM OLAP metamodel with fuzzy stereotypes. Currently there is no formal method that allows to realize this kind of transformations.

The results of research done by CETRA showed that one of the causes that were causing demurrages in returning the empty containers was the stripping time at the consignee warehouses. Palletising the cargoes into the containers decreases substantially stuffing and stripping times. However, there are other technical and economic factors which have to be taken into account in order to take a decision. For that reason, they are employed survey methods, case studies and valuating technical-economic indicators. As a result it was obtained the definition of the cargoes feasible to palletise, which of them not, and in what kind of container, so as the rules to take into account in order to palletise cargoes.
