Modeling and optimizing the integrated problem of closed-loop supply chain network design and disassembly line balancing

This paper describes an integrated model that jointly optimizes the strategic and tactical decisions of a closed-loop supply chain (CLSC). The strategic level decisions relate to the amounts of goods flowing on the forward and reverse chains. The tactical level decisions concern balancing disassembly lines in the reverse chain. The objective is to minimize costs of transportation, purchasing, refurbishing, and operating the disassembly workstations. A nonlinear mixed integer programming formulation is described for the problem. Numerical examples are presented using the proposed model.     

Understanding the Benefit Sought by Rural Tourists and Accommodation Preferences: A South Korea Case

Rural tourism has been widely acknowledged for its effectiveness in contributing to rural areas’ development. With strong government support, rural tourism has developed in many countries during the last several decades. This study aims to improve the understanding regarding tourism in Korean rural areas using a segmentation approach. The responses of 442 tourists in 23 rural villages were analyzed. Four segments of tourists were identified based on the different benefits they sought for their vacation in rural establishments. The estimation of a multinomial logit model determined the socio‐demographic characteristics and the preferred accommodations of a rural tourist. Discussions and implications of the detailed findings are provided in the last section. Copyright © 2012 John Wiley & Sons, Ltd.     

Global supply chain design: A literature review and critique

In this paper, we review decision support models for the design of global supply chains, and assess the fit between the research literature in this area and the practical issues of global supply chain design. The classification scheme for this review is based on ongoing and emerging issues in global supply chain management and includes review dimensions for (1) decisions addressed in the model, (2) performance metrics, (3) the degree to which the model supports integrated decision processes, and (4) globalization considerations. We conclude that although most models resolve a difficult feature associated with globalization, few models address the practical global supply chain design problem in its entirety. We close the paper with recommendations for future research in global supply chain modeling that is both forward-looking and practically oriented.

Design vs. Content: A Study of Adolescent Girls' Website Design Preferences

This study considered the utility of gender schema theory in examining girls' website design preferences. It built on a previous study which identified eight website evaluation criteria related to biological sex: collaboration, social connectivity, flexibility, motility, contextuality, personal identification, inclusion, and graphic/multimedia concentration. Eleven fourteen-, fifteen-, and sixteen-year-old girls participated in the study. The participants completed the short form of the Children's Sex-Role Inventory (CSRI). Following 50-minute Web searching sessions, they were divided into a feminine-high group and a masculine-high group based on their CSRI scores. Each group then participated in interviews concerning their website evaluation and design preferences. Data analysis identified relationships between gender schema and five of the proposed criteria: social connectivity, flexibility, motility, inclusion, and graphic/multimedia concentration. More generally, members of the feminine-high group favored evaluation criteria relating to graphic and multimedia design, whereas members of the masculine-high group favored evaluation criteria relating to subject content. These results indicate that gender schema theory can indeed serve as a framework for making website design more appealing to female adolescent users.
