Supply chain performance management is the essential part of various business activities in supply chain management area, and integrating it with general business management improves the supply chain performance. Although supply chain performance management is important and expected of market growth, there are few researches on this area and lack of practical applications. To resolve these problems, this paper presents a new performance management methodology for a supply chain integrating SCOR (Supply Chain Operational Reference) model and Balanced Scorecard (BSC). And we develop a framework of the Supply Chain Performance Management System (SCPMS) based on this methodology, and implement a prototype system.

Purpose: Research on supply chain sustainability is important for exporters When the factor of sustainable development is considered by the businesses as well as governments of all countries. Research on supply chain sustainability is important for exporters. Sustainable supply chain management and supply chain dynamics will help enterprises adapt to changes in the business environment. This study analyzes the impact of sustainable supply chain management, and supply chain dynamic capabilities on the sustainable development of exporting enterprises in Vietnam. Research design, data, and methodology: The research model and survey are designed based on previous studies after surveying export enterprises. With 185 samples collected from export enterprises. The Structural Equation Modeling (SEM) analysis technique is used. Data analysis is performed on SPSS and AMOS software (Reliability test, Confirmatory Factor Analysis, SEM). Results: Sustainable supply chain management and supply chain dynamic capabilities all have positive effects on the sustainable development of businesses (sustainable development is measured by distribution: measuring economic efficiency, social efficiency, and environmental performance). Conclusions: From the results of this study, the authors also made several recommendations to help export enterprises develop sustainability based on sustainable supply chain management and supply chain dynamic capabilities.

수자원 개발이 인문 사회적 여건으로 날로 어려워짐에 따라 공급위주의 물 관리 정책이 한계에 달하고 이어 수요관리개념에 따른 적용 가능한 수자원관리 기법의 개발이 필요해지고 있다. 무효방류량을 최소화하여 한정된 물 자원 배분을 합리적으로 이룰 수 있는 실제 적용 가능한 수요관리기법은 수자원의 효율적 이용과 유역물관리 시스템의 방법론적 완성을 위해 반드시 필요하다. 본 연구는 기존의 물수지분석 기법을 댐 연계운영 모형과 조합하여 MIP 기법에 의해 이수목적 다목적댐 최적연계운영모형을 개발하고 낙동강 수계를 대상으로 모형의 적용성에 대한 검증을 실시하였으며 낙동강 수계의 용수공급능력을 재평가하였다. 이 결과를 계획 당시 자료 및 다른 모형에 의한 운영결과와 비교한 바 개발된 모형은 훌륭히 물 부족량 공급방식으로 수계의 물 공급을 보장할 수 있고 기존 모형등에 의한 방식보다 물배분과 관리에 효율적으로 활용 될 수 있음이 평가되었다.

We develop an intelligent information system in a multilayer electronic supply chain network. Using the internet for supply chain management (SCM) is a key interest for contemporary managers and researchers. It has been realized that the internet can facilitate SCM by making real time information available and enabling collaboration between trading partners. Here, we propose a multi-agent system to analyze the performance of the elements of a supply network based on the attributes of the information flow. Each layer consists of elements which are differentiated by their performance throughout the supply network. The proposed agents measure and record the performance flow of elements considering their web interactions for a dynamic route selection. A dynamic programming approach is applied to determine the optimal route for a customer in the end-user layer.

Supply chain is viewed as a number of organizations(at least three) working cooperatively with at least some shared objectives. The concept of supply chain management represents the most advanced state in the evolutionary development of purchasing, procurement and other supply chain activities. This study aims to analyze and develop a measurement instrument for supply chain performance in international logistics. A measurement instrument for supply chain performance in international logistics are developed by Lai et al(2002). Supply chain reliability, customer service and cost are constructed reflecting service effectiveness and operations efficiency between shipper, forwarder and liner. The results of this study are as follow. We firstly tested the measurement properties of the sub-dimension of the supply chain performance construct using reliability test and confirmatory factor analysis follow by exploratory factor analysis. For each of the factor, reliability and validity are achieved because of the significant loading of the measurement items on their latent factors. Further research perform the analysis of variance by multi respondents within each firm and across partner firms in the supply chain. The result of analysis present the difference with shipper, forwarder and liner in statistics.

최근 경제는 제조업에서 서비스업으로 이동하고 있기 때문에 서비스 공급사슬을 이해하는 것이 중요하다. 그러나, 공급사슬과 관련된 기존연구의 대부분은 제조업에 집중하고 있다. 이러한 상황을 극복하기 위해서, 서비스 공급사슬을 조사하고 분석할 필요가 있다. 시뮬레이션은 복잡한 시스템을 분석하고 설계하는데 가장 자주 사용되는 기법 중에 하나이다. 서비스 공급사슬은정교한 설계 단계가 필요한 복잡하고 거대한 시스템이다. 특히, 서비스 공급사슬의 성과를 예측하기 위해서 서비스 공급사슬을 구성하고 있는 구성요소 사이의 동적인 상호작용의 행위를 밀접하게 조사하는 것이 중요하다. 본 연구에서는 첫 번째로 서비스공급사슬의 개념적 모델이 개발된다. 다음으로 개발된 서비스 공급사슬의 개념적 모델에 대한 시뮬레이션 모델을 개발하기위한 새로운 절차를 제시한다. 시뮬레이션 모델링의 절차는 UML 분석과 설계 도구를 이용하며 ARENA 시뮬레이션 언어로 구현된다. 제안된 절차의 두 가지 주요한 특성은 서비스 공급사슬을 설계하는데 체계적인 절차의 정의와 또한 ARENA 시뮬레이션 언어로 개념적 모델의 변환에 대한 규칙을 제공한다. 본 연구의 결과는 서비스 공급사슬의 지식을 개선하는데 이용될 수 있으며, 또한 서비스 공급사슬 시뮬레이션 모델의 개발을 효율적으로 할 수 있도록 지원한다.

Increasing global market of used electric vehicle (EV) battery encourages international firms to establish its subsidiary companies or business units specializing in battery recycling. Such kind of companies predominantly use closed loop supply chain (CLSC) for their operations of battery manufacturing and used battery recycling/reusing in global scale. However, EV battery recycling, as a relatively new industry, makes its global CLSC be exposed to various types of risks, which leads to inefficiency of supply processes and makes supply chains more complicated and vulnerable. Identifying, evaluating, and analyzing possible risks in CLSC has a great importance for optimization and increasing effectiveness for the global supply chain of used EV battery. Itwill assist to elaborate the efficient CLSC management and possible risk mitigation strategies to keep the global EV battery supply chain resilient and sustainable. This study aims to develop a conceptual framework for risk assessment in this new sector. Therefore, it will populate the framework with possible failure modes identified from various literature on EV battery recycling and closed loop supply chains so that future research can validate and utilize the conceptual framework.
