The supplier selection problem is perhaps the most important component of the purchasing function. Some of the common and influential criteria in the selection of a supplier include quality, price, delivery, and service. These evaluation criteria often conflict, however, and it is frequently impossible to find a supplier that excels in all areas. In addition, some of the criteria are quantitative and some are qualitative. Thus, a methodology is needed that can capture both subjective and objective evaluation measures. The Analytic Hierarchy Process(AHP) is a decision-making method for ranking alternative courses of action when multiple criteria must be considered. This paper proposes the AHP-based approach which can structure the supplier selection process and the achievements-based procedure which can allocate order quantities for the selected suppliers In automotive part manufacturers. Also, through the practical case of 'D' automotive part manufacturing company, we shows that the proposed AHP based supplier selection approach and the achievements-based allocation procedure of order quantity can be successfully applied for supplier selection and order quantity allocation problems.

While the national economy has rapidly grown, both insufficience in indirect capital facilities of society and attempt to avoid having a logistical job as one of the so-called dirty, difficult and dangerous jobs have resulted in the leak of labor in the logistical industry. First of all, it was shown that the functional utilization level of the logistical information system had a partial effect on the logistical performance, that the reduction of logistical costs was influenced by the information system of connecting and supporting functions, and that the improvement of customer service was significantly influenced by only the supporting-function system. Second, the logistical performance was partially influenced by the linkage between logistical activities, only the customer linkage had a significant effect on the reduction of logistical costs, and the improvement of customer service was influenced by the intra-company linkage. Third, in verifying a hypothesis that the logistical information system's functional utilization level and organizational structure would interact with each other and have an effect on the logistical performance, it was shown that based on their mutual interaction at a normalized level this center's functional information system had a significant effect on the reduction of logistical costs. Fourth, in testing a hypothesis that both the linkage between logistical activities and logistical organization structure would interact with each other and would have an effect on the logistical performance, it was shown that their interaction at a normalized level was significant concerning only the reduction of logistical costs, while there was I10 its significance in the customer service. In proving a hypothesis that the linkage between logistical activities and logistical strategy patterns would interact with each other and would have an effect on the logistical performance, it was shown in a differentiated, aggressive investment one among variously patterned logistical strategies that the customer linkage had a significant effect on the reduction of logistical costs, and in the improvement of customer service that the supplier linkage had a remarkable impact. It also was shown that in case of the cost reduction and offensive control strategy, the customer linkage had a remarkable effect, and th at in the improvement of customer service the intra-company and customer linkage had a significant effect. In the marketing and customer service strategy, finally, there was no any significant influence while the customer linkage had a significant impact in the improvement of customer service. Accordingly, whether or not individual companies utilize the logistical information system's functional utilization levels well will have an effect on their logistical performance, and how their supply chain management is well-linked will affect their logistical performance.

In SCM (supply chain management), companies are pursuing a new approach through which overall functions within the supply chain, ranging from material purchase to production, distribution, and sales are designed, planned, and managed in an integrated way. The core functions among them are production planning and distribution planning. As these problems are mutually related, they should be dealt with simultaneously in an integrated manner. SCM is large-scale and multi-stage problems. Also, its various kinds of internal or external factors can, at any time, dynamically bring a change to the existing plan or situation. Recently, many enterprises are moving toward an open architecture for integrating their activities with their suppliers, customers and other partners within the supply chain. Agent-based technology provides an effective approach in such environments. Multi-agent systems have been proven suitable to represent domains such as supply chain networks which involve interactions among manufacturing organization, their customers, suppliers, etc. with different individual goals and propriety information. In this paper, we propose a multi-agent system based on the genetic algorithm that make it possible to integrate the production and distribution planning on a real-time basis in SCM. The proposed genetic algorithm produced near optimal solution and we checked that there is a great difference in the results between integrated planning and non-integrated planning.

The purpose of this study is to develop business models for current situational scenarios reflecting customer needs emphasize the need for implementing a logistics cooperation system by analyzing big data to strengthen SCM competitiveness capacities. For healthcare SCM competitiveness needed for the logistics cooperation usage intent, they were divided into product quality, price leadership, hand-over speed, and process flexibility for examination. The wordcloud results that analyzed major considerations to realize work efficiency between medical institutes, words like unexpected situations, information sharing, delivery, real-time, delivery, convenience, etc. were mentioned frequently. It can be analyzed as expressing the need to construct a system that can immediately respond to emergency situations on the weekends. Furthermore, in addition to pursuing communication and convenience, the importance of real-time information sharing that can share to the efficiency of inventory management were evident. Accordingly, it is judged that it is necessary to aim for a business model that can enhance visibility of the logistics pipeline in real-time using big data analysis on site. By analyzing the effects of the adaptability of a supply chain network for healthcare SCM competitiveness, it was revealed that obtaining competitive capacities is possible through the implementation of logistics cooperation. Stronger partnerships such as logistics cooperation will lead to SCM competitive capacities. It will be necessary to strengthen SCM competitiveness by searching for a strategic approach among companies in a direction that can promote mutual partnerships among companies using the joint logistics system of medical institutes. In particular, it will be necessary to search for ways to utilize HCSM through big data analysis according to the construction of a logistics cooperation system.

Information lead time is defined as the time spent by processing orders from some buyers, whereas order lead time is defined as producing and supplying the products. The information lead time significantly serve to magnify the increase in variability due to demand forecasting. This paper models a decentralized supply chain composed of cascade type which has four type phases (or divisions) such as retailer, wholesaler, distributor, and factory. Each phases is managed by different centers individually with their own local inventory information. We investigate whether each phase's Information lead time affects companies networked a value chain. In particular, on several experiments performed with a programmed simulation (like a MIT beer game), we study the following question ; Can information lead times do better than material lead times in cost-benefit perspective\ulcorner Can more much Information lead times in downstream reasonably do worser than in upstream when playing the simulation\ulcorner In the conclusion, we show the importance of information lead time on a SC and, besides, guarantee that improvement of information lead time in upstream do more effective than one in downstream in cost-benefit perspective.

This paper presents Web service based ASP (WS-ASP) model for QR(Quick Response) system, supply chain management system in the textiles and clothing industry. The Korean textiles and clothing industry is mostly composed of medium and small-sized companies, which are not capable of recruiting If specialists and making a large scale investment in IT. ASP model not only let them obtain QR system at relatively low usage cost, but also take higher vendor risk due to high dependency. This paper argue that WS-ASP model is appropriate for QR systems by complimenting ASP model with lower vender risk, which results from re-integrating software-on-demand services distributed to several QR specialized WS-ASP vendors.
