A business process specification (BPS) plays the role of a contracted business scenario in the execution of the B2B business process instances. XML-based specification languages, such as BPSS, WS-BPEL, etc., are usually adopted for the specifications. However, composing complex XML-based specifications are not easy for humans. As an alternative, graphical modeling languages such as UML and BPMN can be employed. This paper presents an UML-based modeling method for graphically specifying ebXML BPSS instances (namely, business process specifications). UML diagrams, directly matching with ebXML BPSS, can be reused for understanding and generating ebXML BPSS instances. We discuss the value of tile method by developing a business reference library in the area of supply chain management.

Supply chain management(SCM) requires efforts to search for methods for mutual growth with partner companies and to maintain continuous cooperative relations in order to gain a competitive edge. Because information competencies play a big role within the supply chain, it is essential to examine the relationship of information sharing and partnership quality that can affect information competency. In order to maintain continuous business relations between partner companies, it is necessary to identify the obstacles with partner companies resulting from the imbalance of power within a supply chain and to take on a strategic approach for effectively managing such obstacles. Therefore, there is a significant need to discuss strategic approach methods to enable the logic of mutual growth through the CSV that is worth learning from the partner company and the attributes of non-mediated power. CSV will be reviewed from various aspects as a new management paradigm in the future. This study aims at suggesting a continuous growth model for companies by solving social problems through the integration of CSV and the concept of non-mediated power to advance the information competencies of SCM. A total of 142 copies of survey forms for SCM Implementation Companies were using the PLS structural equation modeling for an analysis, and the following are the findings. Results of this study showed that both CSV and non-mediated power had significant impact on information sharing and partnership qualities, and the conclusion that it is possible to enhance information competency through information sharing and partnership quality. Based on this, this study proposes the implication that it is necessary to elevate awareness of CSV and non-mediated power as variables for the coexistence of SCM participating companies.

There is growing concern of the international community for the environmental issues including climate change. Scholars have examined various issues regrading Green Supply Chain Management (GSCM) but they mainly have focused on why firms introduce and implement GSCM from the persecutive of manufacturers. In particular, there has been few studies of green supply chain management in Korea. We investigate the effects of long-term relationships on green supply chain management and the relationship between GSCM and environmental performance. We also examine the relationship between long-term relationships and green information sharing, the effects of green information sharing on the GSCM. The data for this study were collected through a questionnaire survey on firms that participated in the Green Partnership Program of Korea Institute of Industrial Technology. Based on the responses of 155 firms the research model is empirically tested through a structural equation model. We found that long-term relationships facilitate GSCM significantly as it was expected. Green purchase and green product design also appears to improve environmental performance. Long-term relationship appears to affect positively green information sharing. Green information sharing does not have a statistically significant effect on environmental performance but show positive effect on GSCM including green purchase and green product design.

Reference modeling for Collaborative Networked Organizations(CNOs) has just started, and Enterprise Architecture Modeling Languages(EAMLs) for CNOs are very few. Lack of reference models makes it difficult for people to communicate with each other and lack of EAMLs also makes it difficult to implement information systems for CNOs. We propose an EAML for CNO called CAML. It supports (1) multi-level modeling based on Model- Driven Architecture of OMG's for expressive power and efficiency of implementations, and (2) multi-focus modeling based on Zachman Framework for completeness of modeling The effectiveness of the CAML is investigated through modeling of a supply chain and execution of change impact analysis.

SCM is one of the important key issues in Internet-based business environment. Most of companies related to B2B electronic commerce are making their efforts to innovate their existing business process into new integrated supply chain process. SCM system using XML/EDI provides competitive advantage to them by reshaping the relationship between traditional trading partners. This study intends to suggest a prototype of SCM system using XML/EDI. To implement SCM system, we analyze and design the supply chain process by using Unified Modeling Language, with a firm engaged in Korean automobile industry, which is a first vendor to produce a set of LAMP. The implementation of SCM system using UML shows excellent performance in software reuse, extensibility, and the interoperability with corporate internal information systems.

SCM(Supply Chain Management)는 생산의 전후방 프로세스를 하나의 일관된 프로세스로 보고 통합된 관리를 통하여 고객만족을 달성하려는 새로운 흐름이다. 반도체 산업은 생산프로세스가 타 산업보다 복잡하고 사이클 타임이 길며 또한 생산과정도 다른 여러 프로세스의 연결과정으로 구성되어 타 산업의 SCM 모델링과 다르게 정의되어야 한다. 본 연구에서는 주문침투점을 기준으로 반도체 Push 형 SCM 모델과 Pull 형 SCM 모델로 구분하여 각각에 대한 수리적 모형을 제시함으로 생산에서 1차 소비자까지의 SCM 네트워크에 대한 정형화를 시도하였다. Push형 모델에서는 생산량 극대화를, Pull형 모델에서는 납기만족을 전제로 한 이익의 최대화를 목표로 한다.

This paper deals with the construct of e-SCM System for a supply chain of an auto-mobile company. Two first vendors and two second vendors of a bus company are included in the objects of developing e-SCM system. We analyzed the information flow and business process within vendor and between vendors by using data flow diagram, to describe process to-be model of the e-SCM system. And to analyze and design the process of the system, we used Unified Modeling Language.

In this paper, we consider multi-item inventory management. When managing a multi-item inventory, we coordinate replenishment orders of items supplied by the same supplier. The associated problem is called the joint replenishment problem (JRP). One often-used approach to the JRP is to apply a can-order policy. Under a can-order policy, some items are re-ordered when their inventory level drops to or below their re-order level, and any other item with an inventory level at or below its can-order level can be included in this order. In the present paper, we propose a method for finding the optimal parameter of a can-order policy, the can-order level, for each item in a lost-sales model. The main objectives in our model are minimizing the number of ordering, inventory, and shortage (i.e., lost-sales) respectively, compared with the conventional JRP, in which the objective is to minimize total cost. In order to solve this multi-objective optimization problem, we apply a genetic algorithm. In a numerical experiment using actual shipment data, we simulate the proposed model and compare the results with those of other methods.

The information sharing is essential to make collaboration by participants in the collaboration environment. The sharing of the information is necessary to reduce time-to-market of new Product. In this paper, V2-model is proposed far supporting the sharing of the information on product development. V2-model supports collaborative product development in design and supply chain. Through viewpoints, V2-model supports 1) two-level structure that consist of private level and public level ,2) level-up process and 3) product development process. The public level information supports to share the product information on collaborative supply chain and design. The viewpoints in V2-model are divided into public viewpoints that point to the public level information and private viewpoints that point to the private level information. Private viewpoints are transformed into public viewpoints. The extended Topic Map has B-Topic, S-Topic and View for representing V2-model in this paper. The level-up process of V2-model is implemented through the merging of S-Topics. V2-model is implemented with washing machine model using extended Topic Maps. In this model, the public viewpoints and private viewpoints are represented and the level-up process, which transforms private viewpoints into public viewpoints, is implemented.
