This cross-level study of 77 samples from Korean 1st-tier suppliers participating in knowledge-sharing networks examined the impact of partnering(joint establishment of goal and joint problem solving system) on supplier relationship outcomes(competativeness improvement and innovative idea suggestion). The findings showed that joint establishment of goal and joint problem solving system were positively related to both supplier's competativeness improvement and its innovative idea suggestion. Whereas, joint problem solving system did account for a significant variance only in innovative idea suggestion. The findings, further, demonstrated that mutual trust moderated the relationship between joint problem solving system and supplier relationship outcomes. Implications for theory and practice are suggested.

In this study, based on the principal-agent paradigm, we investigate a joint cost reduction activity in a buyer-supplier supply chain where a buyer motivates its operations department and a supplier to reduce the supply chain's production cost. We construct a benefit-sharing model based on the target cost scheme, a basic philosophy in practice which has not been explored in previous studies. The model also incorporates various supply chain issues such as the cooperation of multiple agents, the opportunity loss, and the degree of strategic relationship between the buyer and the supplier. Based on the analysis of the principal-agent model, we investigate the benefit-sharing rule to control agents' actions, and we also provide important managerial implications into supply chain practices via extensive comparative static analyses.

We analyze a systematic relationship between transaction mechanisms and wholesale pricing schemes within a supply-chain with two competing suppliers and a monopolistic retailor. When one of the suppliers changes its transaction mechanism from an independent scheme to a cooperative one, then the wholesale prices of the suppliers become cheaper than before. When one supplier changes its transaction scheme to a cooperative one while the other supplier sticks to the existing independent transaction scheme, we show that the supplier with a cooperative transaction scheme can realize the increased profit via a profit sharing contract with the retailer but the supplier with independent transaction scheme can face the decreased profit. We also show that both suppliers can achieve the higher profits by adopting the cooperative schemes with the retailer.

Cooperative and integrative partnerships between buyers and suppliers are very important for effective operations. Such partnerships should be based on various information technologies developed in recent years. Therefore, we investigated the relationship among IT performance, IT infrastructure and supply chain performance in buyer-supplier linkage using exploratory examination. This analysis is based on survey results of buyer-supplier practitioners in Korean electronics industry. Specifically, we used factor analysis, correlation analysis, and regression analysis. Major findings are as follows. First. buyers' IT performance contributed to enhance their operational & financial performance, and satisfaction. Second, buyers' IT infrastructure improved their financial performance and satisfaction but showed mixed effects on operational performance. Third, suppliers' operational performance enhanced buyers' operational & financial performance, and satisfaction. Fourth, suppliers' IT performance strengthened their operational & financial performance, and satisfaction. Fifth, suppliers' IT infrastructure showed positive relationships with operational performance and satisfaction.

There was a lot of research to integration of the transshipment and inventory problem in supply chain. Such a integration of inventory and transshipment problem called IRP (Inventory Routing Problem). We consider a distribution problem in which a set of products has to be shipped from a supplier to several retailers in a given planning horizon. Transshipment from the supplier to the retailer is performed by vehicles of limited capacity. Each retailer determines replenishment leadtime and order quantity with buffer management. A supplier determines optimal vehicle routing in supply chain. We suggest a heuristic algorithm which be used TOC buffer management in a replenishment problem and a tabu search algorithm in VRP (Vehicle Routing Problem).

Supplier selection process is one of the most important arenas of production and logistics management for many companies. This study explores the application of the analytic network process (ANP) approach for the evaluation of suppliers based on several different evaluation criteria. The ANP approach in this study is capable of providing priorities of suppliers that capture network relationships among several evaluation criteria which are not independent. Therefore this study provides value to practitioners by providing a generic model for supplier selection. In addition, for researchers, it demonstrates further research possibilities for more complex decision making problems using ANP.

The purpose of this research is to investigate success factors for supply chain management. According to the statistical analysis of 98 survey data, we find that the success factors mentioned in this literature(Supplier-Buyer relations, Inter-organizational Coordination, Planning & Control, Information Technology) positively affect the corporate performance. This research also indicates that supply chain management should be implemented according to dependent industrial characteristics and external conditions. We used three key environmental factors: (1) The product exchanged and its technology, (2) the competitive condition in downstream market, (3) capabilities of the suppliers available.

We explore the determinants of long-term relationship between the buyer and the supplier to help suppliers develope a strategy to build long-term relationship with their buyers. Based upon an extensive literature review, we propose three droops of independent variables which may affect long-term relationship, including (a) environmental factors (product complexity, product importance, source dependence, price sensitivity), (b) relational factors(trust, commitment, satisfaction, intention of expansion), (c) operational performance(quality, delivery, cost capability, technical knowhow). The buyer's actual period of relationship with its main supplier is used as a dependent variable. Using hierarchical multiple regression analysis, we empirically test hypotheses, analysing a sample of 290 manufacturing firms in the U.S. The statistical results indicate that the buyer's source dependence, price sensitivity and the supplier's commitment play a significant role in establishing long-term relationship between the buyer and the supplier. However, the supplier's cost capability and technical knowhow in operational performance negatively affect long-term relationship in contrast with our hypotheses. Due to this controversial result, we divide the sample group Into dual sourcing and multiple sourcing environments and reconduct regression analysis in a post hoc manner. The findings show that the supplier's cost capability and technical knowhow are negatively associated with the length of relationship only in the multiple sourcing environment. The results may confirm that both parties' opportunistic behavior is more salient in the multiple sourcing environment than in the single sourcing environment.

The purpose of this study is to examine whether suppliers are able to benefit by means of constructing a relationship-specific intangible asset and participating in collaboration with purchasers to actively maintain value created while mutually using inter-organizational information systems. To achieve the purpose of this study. 82 questionnaires have been analyzed from suppliers which are using electronic transactions through inter-organizational information systems. As a result, business process specificity and domain knowledge specificity, which are relationship-specific intangible assets, affect operational collaboration and strategic collaboration, which are classified by level of decision-making. Although both types of collaboration are needed to achieve both strategic and operational benefits, we find each collaboration to be uniquely promoted by a specific types of relationship-specific intangible asset. Operational collaboration is found to be an antecedent to operational benefit and strategic collaboration is found to be an antecedent to strategic benefits. No crossover between collaboration and supplier's benefits is found. Consequently, the result of this study shows collaboration is needed for domestic suppliers, which have relatively low levels of collaboration, to keep maintain relationship-specific intangible assets and to prevent the relationship termination cost when transactions have been stopped between supplier and purchaser. Also the results imply the supplier can have advantages by participating in collaboration.

The purpose of this study is to find method to meet the greater retailer's supplier assessment requirement So, this study analyze the greater retailer's requirement for supplier assesment and research global standard which is used instead of supplier assessment requirement that is recognized by global retailers initiative. Next, this study analyze domestic aquaculture certification requirement and compare the global standard with the domestic requirement by using The Most Similar Systems Design. As a result, this comparing has founded all of two domestic certifications are similar to global standard's Good Aquaculture Practice module but those are a little bit different from System Element module. Therefore, this study suggest tree alternative. First, make up for the weak points in the current domestic aquaculture certification system. Second, the introduction of global aquaculture management system certification as supporting by government. Third, development of new standard in accordance with global food standard. This study has major implications for research into development of domestic aquaculture standard.
