Supplier selection is an essential task within the purchasing function of supply chain management because it provides companies with opportunities to reduce various costs and realize stable and reliable production. However, many companies find it difficult to determine which suppliers should be targeted as each of them has varying strengths and weaknesses in performance which require careful screening by the purchaser. Moreover, information required to assess suppliers is not known precisely and typically fuzzy in nature. In this paper, therefore, fuzzy multi-objective linear programming (fuzzy MOLP) is presented under fuzzy goals: cost minimization, service level maximization and purchasing risk. To solve the problem, we introduce an enhanced two-phase approach of fuzzy linear programming for the supplier selection. In formulated problem, Analytical Hierarchy Process (AHP) is used to determine the weights of criteria, and Taguchi Loss Function is employed to quantify purchasing risk. Finally, we provide a set of alternative solution which enables decision maker (DM) to select the best compromise solution based on his/her preference. Numerical experiment is provided to demonstrate our approach.

This study is to investigate the impact of information technology implementation on supply chain risk and performance. It focuses on how information technology adoption affects supply risk as well as performance. It collected one hundred fifty nine responses from supply executives and supply and purchasing managers of U.S manufacturing firms by applying a survey methodology. The research results provide empirical evidence that the use of information technology in the supply chain mitigates supply risk and improves performance. More importantly, information technology adoption involves three aspects: inbound and outbound communications, internal communications and administration and finally, mitigation of supply risks and improved performance via order taking and procurement. This research emphasizes the importance of IT implementation in supply risk management. It also points out how information technology adoption facilitates the impact of information technology in risk mitigation in the supply chain and in performance. Thus, supply and purchasing managers need to consider IT implementation and adoption when establishing their risk mitigating strategies within the supply chains.

Private brands play an important role in formulating the marketing strategies of fashion goods. Merchandisers of Korean department stores are now realizing that the effective marketing of private brands can increase customers store loyalty as well as store profitability. Thus, it is important to better understand customer's decision making processes underlying the purchase of private brand apparels. However, Little research had been undertaken to examine integrated factors influencing purchases of private brand apparel. Therefore, the objective of this study is to propose a model of purchasing intentions of private brand apparel. This study pays attention to (1) perceived value, (2) familarity, (3) store image, (4) differenciated needs, (5) perceived risk, and (6) perceived quality variation of private brand. The proposed model supports all hypotheses presented in the paper. Purchase intentions of private brand increased as perceived money, familiarity, positive store image of private brands, and satisfaction of individuals differentiated needs increase. Furthermore, perceive value of private brand increased as perceived risk and quality variation of private brand increased.

This study examines the model of perceived risk, trust, and continuous transaction intentions presented in a study of the buying behavior in International Transaction. Although most of the trade transactions have been studied as a legal supplement, trade transactions are also purchasing behavior aimed at maintaining continuous transaction intentions between the parties. The study results confirmed that perceived risk could be separated into risk neutrality, risk - taking and risk aversion, and perceived risk had an effect on trust. In addition, the trust affected by perceived risk in the trade transaction model has a statistically significant effect on continuous transaction intentions. The study results confirm that the theoretical background used in previous studies of purchase behavior models is also effective in trade transaction.

Purpose - This study aims to illustrate the relationship between demographic factors and perceived risk types, supposing that Korean customers tend to postpone buying or hesitate to purchase the new version of hand sets, because of an early buying risk. Research design, data, and methodology - In addition to existing perceived risk types, the authors introduced an early buying risk. In order to measure each variable, also, the study has employed a five-point Liker-scale. To increase research reliability and validity, the research adopted an exploratory factor analysis, a confirmatory factor analysis, and one-way ANOVA.
