There are usually some leftovers (usable pieces of raw material) and scraps (unusable pieces of raw material).generated after the completion of a manufacturing process. These leftovers consist of many different types, materials, styles and sizes so the use of such materials is difficult to manage, resulting in a significant material management problem for manufacturers. This study examines ways to use these leftovers and proposes the application of a genetic algorithm to handle the problem of matching usable leftovers to incoming orders. In order to verify the feasibility of the solution, a decision support system was implemented, based on a genetic algorithm. With lots of experimental results, we conclude this method is thus of considerable value to the managers of manufacturing factories.

Purpose - The purpose of this paper is to propose an implementation model for enterprise resource planning (ERP) based on resource-based view, and using the dynamic capability theory as its theoretical foundation. This model includes: the establishment of the objectives of the implementation, an assessment of the available resources and the scope of the implementation, the redesign/integration and organizational learning during the process, the implementation of the system, and the measurement and evaluation of its performance. Design/methodology/approach - An integrated circuits design company in Taiwan was used in a case study to examine the validity of the proposed model. Findings - When the proposed ERP implementation model was applied in this study, the results show that organizational coordination, system-process redesign and integration, and organizational learning are the critical strategies for enterprises, in order to reduce the risks during the implementation of ERP projects. Practical implications - This model can help enterprises recognize the resources needed when implementing an ERP. In addition, they need to consider the reliability of these resources, as this will increase the efficiency of the implementation, and thus the probability of success. Originality/value - Studies of past models in the implementation of ERP have been conducted in various industries. There is a need for further studies that evaluate the different concepts in terms of the effectiveness of specific methods, in order to enhance the probability of successfully implementing a dynamic system. This paper is one of the first to explain how an enterprise can implement an ERP that is based on the theory of dynamic capabilities. The case study illustrates the important, critical success factors.

The E-Government standard describes how governments work, share information and deliver services to external and internal stakeholders. It harnesses information and communication technologies (ICTs) to transform relationships with citizens and businesses and between the branches of government. The benefits may include reduced corruption, increased transparency, greater convenience, higher revenues, and lower costs. The current E-Government 2.0 describes user-oriented portal services that are integrated into and provided through one portal site using Web 2.0 technologies, such as RSS, blogs, social networks, etc., and that are accessible from various channels. However, building E-Government 2.0 is difficult because the transition from E-Government to E-Government 2.0 should be an organizational integration agenda, not only a technology one. Agencies may encounter many unpredictable design challenges and tensions that must be managed. Governments are now beginning to focus on the larger and more holistic task of service innovation in order to provide more productive and better services. One of the key observations about making progress with service innovation is that agencies need a framework to help them move forward. Our objective in this study is to propose a novel implementation framework for E-Government 2.0. This framework integrates the processes, resources, back offices, and front offices of online systems to carry out the stakeholder-oriented participatory E-Government 2.0. Finally, we use Korea, Antigua and Barbuda, and Ecuador as cases to validate it. (C) 2014 Elsevier Ltd. All rights reserved.

The driving force behind software development of the Electronic Medical Record (EMR) has been gradually changing. Heterogeneous software requirements have emerged, so how to correctly carry out development project has become a complex task. This paper adopts the knowledge engineering and management mechanism, i.e., CommonKADS, and software quality engineering to improve existing strategic information management (SIM) plan as a design methodology to help software implementation for medical institutes. We evaluate the adopting performance by a real case that examines the maturity level of the architecture alignment between the target solution in the proposed SIM plan and the built medical system.

Purpose - In recent years, many development projects of the medical systems encounter difficulties and eventually fail. Failure is often due to very complicated and changeable medical procedures and the inconsistent understanding between system stakeholders, especially the healthcare providers, and information technology staff. Many research results also indicate that poor communication easily results in negative consequences during the implementation of the medical information system. To effectively overcome this obstacle, the purpose of this paper is to propose an enhanced Delphi method to assist in reaching consensus during the software development with some additional steps. Design/methodology/approach - As an alternative to the traditional way to elicit pertinent feedback from respondents, the enhanced Delphi method stresses the systematic, flexible, and cyclic stages to construct a questionnaire with viewpoints from different types of panelists and a self-assessment procedure as a validating step to measure the improvements in the system implementation. Findings - The better communication between the members of project team does increase the comprehensive assessment of a project. Originality/value - Based on a practical case, the enhanced Delphi method really demonstrates good performance and effectiveness.

The widespread use of the Internet has significantly changed the behavior of homebuyers. Using online real estate agents, homebuyers can rapidly find some modern houses that meet their needs; however, most current online housing systems provide limit features. In particular, existing systems fail to consider homebuyers\' housing goals and risk attitudes. To increase effectiveness, online real estate agents should provide an efficient matching mechanism, personalized service and house ranking with the aim of increasing both buyers\' satisfaction and deal rate. An efficient online real estate agent should provide an easy way for homebuyers to find (rank) a suitable house (alternatives) with consideration of their different housing philosophies and risk attitudes. In order to comprehend these ambiguous housing goals and risk attitudes, it is also indispensable to determine a satisfaction level for each fuzzy goal and constraint. In this study, we propose fuzzy goal programming with an S-shaped utility function as a decision aid to help homebuyers in choosing their preferred house via the Internet in an easy way. With the use of a decision aid, homebuyers can specify their housing goals and constraints with different priority levels and thresholds as a matching mechanism for a fuzzy search, while the matching mechanism can be translated into a standard query language for a regular relational database. Moreover, a laboratory experiment is conducted on a real case to demonstrate the effectiveness of the proposed approach. The results indicate that the proposed method provides better customer satisfaction than manual systems in housing selection service. (C) 2014 Elsevier B.V. All rights reserved.
