The establishment of post-disaster humanitarian logistics (PD-HL) network is essential for humanitarian relief in emergency events, and the research of trust in PD-HL plays a crucial role in building and implementing humanitarian logistics network. This paper analyzes the trust structure of relief patterns in PDHL network based on three topology models: ACE (Agency Centric Efforts), PIE (Partially Integrated Efforts) and CAN (Collaborative Aid Networks). Three kinds of in?uence matrices of PD-HL networks are constructed and simulated through NK model to analyze the trust structure in three indicators including global optimum,the average of local optimum and the number of local optimum. Finally, several recommendations are given for the operations of PD-HL.

Recently almost all advanced companies own transactional ITs such as POS (point-of-sales), ERP (enterprise resource planning), MRP (material requirement planning), etc. Since analytic processes are necessary to obtain significant information from them, decision makers of most of those companies can not utilize the outcomes directly. A modern and advanced IT system consisting of models and algorithms is called analytic IT. The objective of the analytic IT is to help the decision maker. In this paper, we survey the supply chain (SC) optimization. We introduce three decision levels of the SC and show the classification of inventories. We also discuss several basic optimization models such as logistics network design, inventory, scheduling, lot-sizing, and vehicle routing models.

As one kind of regional finance institutions (RFIs), shinkin banks have closer relations with development of regional economies than city banks. This paper aims to apply principal components analysis to evaluate the performance of shinkin banks' contribution to regional economies in northeast area of Japan. Different from the existing studies, this paper is the first attempt to use principal components analysis to analysis of shinkin banks. Meanwhile, we limit our analysis to 27 shinkin banks in the northeast area of Japan and put our emphasis on extracting an effective indicator to measure the contributions of the shinkin banks to regional economies and clarify the issues for the shinkin banks to improve or strengthen their regional contribution.

In this paper, we attempt to clarify the social consequences of the changes in the Northeast Asian labor market based on the results of a questionnaire survey on changes in Žexibility and security, which was carried out among workers in Japan, China, and Korea. In particular, we analyzed the reality of institutional development in employment,income, vocational training, and work-life balance in the labor market in three Northeast Asian countries by estimating the adaptation range of institutions in labor market. Furthermore, we attempted to undertaken an international comparative analysis on perceptions about work, leisure, and work-life balance under the institutions.

Major studies on cell production have put the emphasis on technical factors (machine order/layout, family part grouping, workŽow sequence, etc.), it is still insufficient to investigate how workers' aptitude affect the productivity of production cells. As the first attempt to examine the workers' aptitude toward the assembly tasks in production cells,we make a comparatively detailed literature review on the major theories and assessment measures developed in the field of industrial and organizational psychology. Then we give the definition of four aptitudes and related hypotheses from the aspects of workers' cognition and interest, finger dexterity, affection, and behavioral intention. We design a self-evaluation sheet to measure the workers' aptitudes, and moreover design a cell production experiment to investigate the relation between the workers' aptitudes and productivity of production cells. Through our experimental study, we verified statistically that the workers' cognition and interest, negative affection correlate significantly to the productivity of production cells. However, there are still some issues to be addressed further in order to measure the workers' aptitudes through the self-evaluation sheet.
