Simultaneous configuration of platform products and manufacturing supply chains

The product platform concept represents a powerful approach for manufacturers to compete cost-effectively in a global market that requires diverse product range, quick time to market, and rapid responses to supply sources. A key challenge is how to strike a balance between platform commonality and modularity. When a manufacturer outsources its raw materials or module options, the supplier capabilities and production costs should be considered. This paper discusses optimizing decision variables for simultaneously configuring not only platform-based product variants but also their supply chain. We develop a mixed-integer programming model that integrates both platform product design and material purchase decisions based on cost drivers sensitive to commonality and modularity. Theoretical analysis of the model yields two properties, allowing us to further simplify the model and thus help in developing an effective solution algorithm. A numerical example is presented to illustrate how manufacturers strive to dynamically adjust their product design strategies in response to changes in the market demands and/or supply base.link_to_subscribed_fulltex

College students and credit card companies: Implications of attitudes

More knowledge and understanding is needed regarding the mechanisms influencing college student attitudes toward credit card companies and the behavior that students exhibit using credit cards. Prior literature in the area has been sparse. The current article is an attempt to fill the gap in existing literature. Using survey data, we try to find the determinants of college student attitude toward credit card companies and the responsible use of credit cards. Our findings indicate that a strong positive link exists between student attitude toward credit card companies and responsible credit behavior. Two distinct groups of students are identified - one with a positive attitude toward credit card companies and positive credit use behaviors; the other with the opposing attitude and behavior. Reward cards, payment behavior, number of credit cards, modes of acquisition, awareness about credit card policies, purpose for using credit cards, impulsiveness and certain student characteristics are all indicated as variables that help discriminate between the two different student groups. Our findings have implications for both higher education institutions and credit card firms

Relationship between supply chain integration and performance

This study analyzes survey-based studies examining the benefits of supply chain integration (SCI) and presents opportunities for further empirical examination. The literature review method is used to evaluate the empirical research published from 1990 to 2012. The analysis reveals that internal integration serves as a foundation for establishing external collaboration. There is empirical evidence on the positive effect of supplier integration on performance, whereas the findings on benefits through customer integration are conflicting. While researchers have made significant progress in our understanding of SCI, there is a substantial need for more work to provide in-depth insights into the potential of SCI and to improve the methodological issues. This study makes three contributions. First, this study expands the current understanding of benefits and considerations in implementing internal, supplier, and customer integration. Second, this study provides a critique of the empirical work and offers research agendas that can stimulate future researchers to carefully explore the topic. Finally, this study enhances the quality of analysis by employing the five-step approach proposed by Vokurka and O\u27Leary-Kelly (J Oper Manag 18(4):485-501, 2000). © 2013 Springer Science+Business Media New York
