    Green environmental performance increases the competitiveness of the supply chain. However, the greening of the supply chain depends on the manufacturer who drives the green initiative, as well as on all the members of the supply chain who take part in the process. The manufacturer’s attention has been largely focused on the environmental performance of the supplier and retailer, whereas logistics service providers have been somehow neglected. It is, in fact, the case is that logistics service providers have begun to play a critical role in supply chain management and could therefore significantly improve environmental sustainability. They have already undertaken a green initiative that unfortunately has rarely, if at all, been required by the manufacturer. The lack of requirements for logistics providers hinders the progress of a green initiative. To take a step forward towards green supply chain management, this chapter aims to introduce all the necessary criteria for the selection of a logistics service provider (LP), with an emphasis on environmental criteria. The environmental selection criteria, with all related subcriteria, were achieved on the basis of a systematic literature review. It has been found that buyers of logistics services still strive to minimize costs, expect quality logistics services, a well-positioned LP, all the while overlooking environmental issues. The most frequently applied environmental selection criteria are value-added reverse logistics services, followed by environmental expenditures, pollutants released, energy consumption, clean materials and energy use. The findings presented here are useful particularly for researchers, as issues regarding sustainable LP selection and its limitations are highlighted, related to selection criteria identification. These findings may be of less use to managers. However, future phases of this study, richer for the evaluation of logistics experts, will be much more applicable to buyers and providers of logistics services

    Prioritizing Offshore Vendor Selection Criteria for the North American Geospatial Industry

    The U.S. market for geospatial services totaled US $2.2 billion in 2010, representing 50% of the global market. Data-processing firms subcontract labor-intensive portions of data services to offshore providers in South and East Asia and Eastern Europe. In general, half of all offshore contracts fail within the first 5 years because one or more parties consider the relationship unsuccessful. Despite the high failure rates, no study has examined the offshore vendor selection process in the geospatial industry. The purpose of this study was to determine the list of key offshore vendor selection criteria and the efficacy of the analytic hierarchy process (AHP) for ranking the criteria that North American geospatial companies consider in the offshore vendor selection process. After the selection of the initial list of factors from the literature and their validation in a pilot study, a final survey instrument was developed and administered to 15 subject matter experts (SMEs) in North America. The SMEs expressed their preferences for one criterion over another by pairwise comparisons, which served as input to the AHP procedure. The results showed that the quality of deliverables was the top ranked (out of 26) factors, instead of the price, which ranked third. Similarly, SMEs considered social and environmental consciousness on the vendor side as irrelevant. More importantly, the findings indicated that the structured AHP process provides a useful and effective methodology whose application may considerably improve the quality of the overall vendor selection process. Last, improved and stabilized business relationships leading to predictable budgets might catalyze social change, supporting stable employment. Consumers could benefit from derivative improvements in product quality and pricing

    Automatic Service Agreement Negotiators in Open Commerce Environments

    There is a steady shift in e‑commerce from goods to services that must be provisioned according to service agreements. This study focuses on software frameworks to develop automated negotiators in open commerce environments. Analysis of the litera‑ ture on automated negotiation and typical case studies led to a catalog of 16 objective requirements and a conceptual model that was used to compare 11 state-of-the-art software frameworks. None of them was well suited for negotiating service agreements in open commerce environments. This motivated work on a reference architecture that provides the foundations to develop negotiation systems that address the previous requirements. A software framework was devised to validate the proposal by means of case studies. The study contributes to the fields of requirements engineering and software design, and is expected to support future efforts of practitioners and researchers because its findings bridge the gap among the existing automated negotiation techniques and lay the founda‑ tions for developing new software frameworksMinisterio de Educación y Ciencia TIN2006–00472Ministerio de Ciencia e Innovación TIN2009–07366Junta de Andalucía P07-TIC-2533 (Isabel)Ministerio de Educación y Ciencia TIN2007–64119Junta de Andalucía P07-TIC-02602Junta de Andalucía P08-TIC-4100Ministerio de Ciencia e Innovación TIN2008–04718-

    A fuzzy hierarchical decision model and its application in networking datacenters and in infrastructure acquisitions and design

    Get PDF
    According to several studies, an inordinate number of major business decisions to acquire, design, plan, and implement networking infrastructures fail. A networking infrastructure is a collaborative group of telecommunications systems providing services needed for a firm\u27s operations and business growth. The analytical hierarchy process (AHP) is a well established decision-making process used to analyze decisions related to networking infrastructures. AHP is concerned with decomposing complex decisions into a set of factors and solutions. However, AHP has difficulties in handling uncertainty in decision information. This study addressed the research question of solutions to AHP deficiencies. The solutions were accomplished through the development of a model capable of handling decisions with incomplete information and uncertain decision operating environment. This model is based on AHP framework and fuzzy sets theory. Fuzzy sets are sets whose memberships are gradual. A member of a fuzzy set may have a strong, weak, or a moderate membership. The methodology for this study was based primarily on the analytical research design method, which is neither quantitative nor qualitative, but based on mathematical concepts, proofs, and logic. The model\u27s constructs were verified by a simulated practical case study based on current literature and the input of networking experts. To further verify the research objectives, the investigator developed, tested, and validated a software platform. The results showed tangible improvements in analyzing complex networking infrastructure decisions. The ability of this model to analyze decisions with incomplete information and uncertain economic outlook can be employed in the socially important areas such as renewable energy, forest management, and environmental studies to achieve large savings

    Effective Strategies for Managing the Outsourcing of Information Technology

    Get PDF
    More than half of information technology (IT) outsourced projects fail, primarily due to a lack of effective management practices surrounding the outsourcing end-to-end process. Ineffective management of the IT outsourcing (ITO) process affects organizations in the form of higher than expected project costs, including greater vendor switching or reintegration costs, poor quality, and loss of profits. These effects indicate that some business leaders lack the strategies to effectively manage the ITO process. The purpose of this single-case study was to apply the transaction cost economics (TCE) theory to explore strategies 5 business professionals use to manage an ITO project in a financial services organization located in the Midwestern region of the United States. Participant selection was purposeful and was based on the integral role the participants play on the ITO project. Data collection occurred via face-to-face semistructured interviews with the participants and the review of company documents. Data were analyzed using inductive coding of phrases, word frequency searches, and theme interpretation. Three themes emerged: vendor governance and oversight, collaborative strategic partnership, and risk management strategies enabled effective management of ITO. Identifying and executing appropriate outsourcing strategies may contribute to social change by improving outsourcing infrastructure, which might support job creation; increasing standards of living, especially within emerging markets; and heightening awareness of different cultures, norms, and languages among people living in different regions around the world to establish commonalities and gain alignment with business practices

    Barriers to coastal shipping development: an Indian perspective

    Get PDF
    Coastal shipping has been widely recognised as a sustainable and efficient alternative to road transport. However, the barriers encountered in the industry have not been systematically studied in any region. From an Indian perspective, this study aims to prioritise barriers to coastal shipping development for effective policy interventions. It identifies important barriers through a Delphi study and then quantifies their cause-and-effect relationships by the decision making-trial and evaluation laboratory analysis (DEMATEL) technique. It is interesting that the main barriers, those have most impact on coastal shipping development, are not necessarily the ones most widely recognised. The study also uncovers the hidden cause-and-effect relationships between several barriers. Four main barriers are identified: (1) Indian maritime legislation (especially cabotage rules); (2) issues in the infrastructure and procedures at port and port-centric areas; (3) underdevelopment of small ports; (4) lack of a collaborative culture among the various service providers involved in the logistics supply chain. This study finally recommends relaxing cabotage rules to stimulate the inflow of foreign capital to grow coastal shipping, improving the current port system through joint efforts of the ports, Indian customs and government, and fostering supply chain collaboration

    A multi-criteria fuzzy method for selecting the location of a solid waste disposal facility

    Get PDF
    Facility location is a multicriteria decision process that has important operational and economic impacts and that typically involves uncertainty and vagueness of evaluations. A fuzzy-based method supporting preliminary decision-making about siting solid waste incinerators is proposed building on a structured classification of criteria for location selection developed from the existing literature. The application to a case study revealed the advantages of the methodology. The work intends to provide a general and comprehensive taxonomy of decision criteria that may be adapted to various facility location problems together with a fuzzy inference process that is useful for companies and public administration institutions looking for rigorous but relatively simple decision-making tools in uncertain environments. Future research will compare the developed method with the most common tools for making location decisions. The approach will be then extended to different kinds of facilitie

    Fuzzy linear programming problems : models and solutions

    No full text
    We investigate various types of fuzzy linear programming problems based on models and solution methods. First, we review fuzzy linear programming problems with fuzzy decision variables and fuzzy linear programming problems with fuzzy parameters (fuzzy numbers in the definition of the objective function or constraints) along with the associated duality results. Then, we review the fully fuzzy linear programming problems with all variables and parameters being allowed to be fuzzy. Most methods used for solving such problems are based on ranking functions, alpha-cuts, using duality results or penalty functions. In these methods, authors deal with crisp formulations of the fuzzy problems. Recently, some heuristic algorithms have also been proposed. In these methods, some authors solve the fuzzy problem directly, while others solve the crisp problems approximately
