Carbon emissions are an increasingly important consideration in sustainable environmental development. In the green building industry, green construction cost controls and low-carbon construction methods are considered to be the key barriers encountered. Based on Corporate Social Responsibility (CSR) policy, management of carbon emissions from green building projects contributes to the acquisition of accurate building cost information and to a reduction in the environmental impact of these projects. This study focuses on the CO2 emission costs and low-carbon construction methods, and proposes a 0–1 mixed integer programming (0–1 MIP) decision model for integrated green building projects, using an Activity-Based Cost (ABC) and life cycle assessment (LCA) approach. The major contributions of this study are as follows: (1) the integrated model can help construction company managers to more accurately understand how to allocate resources and funding for energy saving activities to each green building through appropriate cost drivers; (2) this model provides a pre-construction decision-making tool which will assist management in bidding on environmentally-friendly construction projects; and (3) this study contributes to the innovation operation research (OR) literature, especially in regard to incorporating the life cycle assessment measurement into construction cost management by utilizing a mixed decision model for green building projects.

In this study, the performance of the internal audit department IAD and its contribution to a company under enterprise resource planning ERP systems was examined. It is anticipated that this will provide insight into the factors perceived to be crucial to a company’s effectiveness. A theoretical framework was developed and tested using the sample of Taiwanese companies. Using mail survey procedures, we elicited perceptions from key internal auditors about the ERP system and auditing software, as well as their opinions concerning the IAD’s effectiveness and its contribution within a company. Data were analysed using the partial least square PLS regression to test the hypotheses. Drawing upon a sample of Taiwanese firms, the study suggests that a firm can improve the performance of the IAD through an enterprise-wide integrated, effective ERP system and appropriate auditing software. At the same time, the performance of the IAD can also contribute significantly to the company. The results also show that investments in computer-assisted auditing techniques CAATs are crucial due to their tremendous effectiveness in regard to the performance of the IAD and for the contributions CAATs can make to a company.

A particular decision-making process that is needed by most firms who produce joint products is the one requiring an assessment of desirability of further processing joint products beyond the split-off point. The purpose of this paper is to develop an algorithm for optimizing a joint products further processing decision under the theory of constraints. To fit the jointly produced characteristic of joint products and the sequential produced characteristic between each joint product and its further processing product, the algorithm is composed of seven steps. These steps consider every bottleneck resource to the decision-making process by computing a priority ratio to establish its priority sequence. According to the priority sequence of the most constrained resource, the initial master production schedule is developed. Then, the following steps find the best path to reach the optimal solution under the guidance of all bottleneck resources. Due to its accessibility and comprehensibility, the TOC-based algor...

In response to the international trend, in recent years companieshave officially adopted the International Financial Reporting Standards (IFRSs) and need to perform upgrade or adjustment to their Enterprise Resource Planning (ERP) systemsfor the IFRS conversion. Information technology (IT) governance in an ERP system environment will become akey that cannot be ignored by the management. To investigate the impact of implementing IT governance in an ERP environment on the effectiveness of ERP implementation and IFRS conversion The findings are as follows: Effective IT governance in a company can improve the project performance of ERP implementation; The improvement of the information quality and system qualityofan ERP system candemonstrate the effectiveness of the IFRS conversion through the ERP system; The project performance of ERP implementation can improve the information quality and system quality of the ERP system as well as the effectiveness of the IFRS implementation.

Companies declare that quality or customer satisfaction is their top priority in order to keep and attract more business in an increasingly competitive marketplace. The cost of quality (COQ) is a tool which can help determine the optimal level of quality investment. COQ analysis enables organizations to identify measure and control the consequences of poor quality. This study attempts to identify the COQ elements across the enterprise resource planning (ERP) implementation phases for the ERP implementation services of consultancy companies. The findings provide guidance to project managers on how best to utilize their limited resources. In summary, we suggest that project teams should focus on “value-added” activities and minimize the cost of “non-value-added” activities at each phase of the ERP implementation project. Key words: Services, ERP implementation services, quality standard, service quality standard, cost of quality, project management, project quality management, project financial management.

The implementation team problem is one of the critical elements lead to ERP project failure. The purpose of this research is to explore the relationship between team risk factors and IT governance. The IT governance includes five important domains, that is, IT strategic alignment, IT value delivery, IT resource management, IT risk management, and IT performance management. Our research results indicate that, among five domains of IT governance, strategic alignment is the most important area. As for the team risk factors, two main team risk factors are “Lack of cross-functional team members” and “IT members’ lack of specialized knowledge required by the ERP project”. Companies that encountered these team risk factors during ERP project implementation have lower IT governance achievement level than those that did not. It is suggested that Corporations should train their IT members in specialized ERP knowledge and set up a cross-functional team for ERP implementation in order to achieve effective IT governance.

Enterprise resource planning (ERP) systems are used to provide companies with integrated information for operations management and decision-making. An ERP implementation project may become a troubled project at any stage during the life cycle of the project. We must detect and correct the causes of a project’s problems before it fails. This study investigated troubled ERP implementation projects, sought the root causes of the troubled projects and determined what actions could be taken to turn around the troubled projects. We used case study methodology. The purpose of this study was to help determine whether a project is troubled and summarise possible management methods for saving a project, while it is still possible or cancelling it with minimal negative impact.

The 21st century is an era of globalisation. With the rapid changes in the global economic environment, many companies are aware that they need to promote their competitiveness by adopting more information technology, such as enterprise resource planning (ERP). Implementing ERP into a company is difficult, let alone implementing a global ERP system. The purpose of this paper was to demonstrate how to successfully implement a global ERP rollout by using the case study method. The lessons learned from this effort should help to support further academic and practitioner literature, especially in the area of global ERP rollout.
