The efficiency of a supply chain can be extremely affected by its design which includes determining the flow pattern of material from suppliers to costumers, selecting the suppliers, and defining the opened facilities in network. In this paper, a multi-objective multi-echelon multi-product supply chain design model is proposed in which several suppliers, several manufacturers, several distribution centers as different stages of supply chain cooperate with each other to satisfy various costumers' demands. The multi-objectives of this model which considered simultaneously are 1-minimize the total cost of supply chain including production cost, transportation cost, shortage cost, and costs of opening a facility, 2-minimize the transportation time from suppliers to costumers, and 3-maximize the service level of the system by minimizing the maximum level of shortages. To configure this model a graph theoretic approach is used by considering channels among each two facilities as links and each facility as the nodes in this configuration. Based on complexity of the proposed model a multi-objective Pareto-based vibration damping optimization (VDO) algorithm is applied to solve the model and finally non-dominated sorting genetic algorithm (NSGA-II) is also applied to evaluate the performance of MOVDO. The results indicated the effectiveness of the proposed MOVDO to solve the model.

Purpose: Supply chain management is a significant component of marketing strategy to achieve the overall goal of maintaining a competitive edge in the industry. To better understand and compare marketing strategies between two major distribution channels (Wholesalers and Retailers), the present study examines the various critical aspects in developing marketing strategies based on numerous prior studies. Research design, data and methodology: Qualitative research involves collecting and analyzing various non-numeric data to establish different concepts or opinions in the data. In content analysis, determining the presence of different themes, concepts, or other valuable texts and their relationships is carried out. Usually, the researchers employ three distinct methods to carry out complete content analysis. Results: Developing the appropriate marketing strategy to manage the supply chain of a business is essential. Marketing strategies should be formulated in a manner that ensures the supply chain is well organized. Applying the marketing strategy in the supply chain management, the current author utilizes the four Ps to integrate strategies for two distribution channels which are essential in ensuring proper management. Conclusions: This study concluded that utilizing the existing marketing strategies and integrating them can help in better management of the supply chain, using communication, decision making, product differentiation, and pricing.

네트워크를 구축한 대기업에게 있어서 지속가능한 공급사슬 관리(SSCM)는 기업 전체의 사회적 성과뿐만 아니라 기업의 장기적인 경쟁 지위를 결정하는 요인이 되었다. 이러한 실무 세계의 변화에도 불구하고 어떤 요인이 대기업의 SSCM 체계 구축을 촉진하고, SSCM이 대기업에 어떠한 가치를 부가하는 지에 대한 체계적인 실증 연구가 거의 없었다. 본 연구는 이러한 선행 연구의 갭(gap)을 메우기 위하여 첫째, 조직 외부의 이해관계자로서 고객의 사회적 책임 압력과 조직 내부의 이해관계자로서 구매관리자의 사회적 책임 의식이 각각 SSCM 변수인 공급사슬 투명성과 상생협력에 미치는 영향을 분석하고, 둘째, 공급사슬 투명성과 상생협력이 각각 결과변수인 기업 명성에 미치는 영향을 분석했다. 우리나라를 대표하는 대기업 69개를 대상으로 하여 실증 분석한 결과, 고객의 사회적 책임 압력과 구매관리자의 사회적 책임 의식은 공급사슬 투명성에 정(正)의 유의한 영향을 미치는 것으로 나타났고, 상생협력에는 구매관리자의 사회적 책임 의식만이 정(正)의 유의한 영향을 미치는 것으로 나타났다. 한편, 공급사슬 투명성과 상생협력은 모두 기업 명성에 정(正)의 유의한 영향을 미치는 것으로 나타났다. SSCM의 영향 요인과 성과를 새로운 관점에서 분석한 본 연구는 조직 간의 거래, 특히 공급사슬 관련 이론을 심화·확장시켰다는 의의를 지닌다.

In this paper, we propose a linear programming model of supply planning process for the supply chain collaboration strategy of a company. The amount of its supplying quantity relies on outsourcing suppliers heavily. Conversely, the revenues of those suppliers are highly dependent on the supplying quota from the supply network planning of the company. In order to keep the supply stable through collaboration, the company builds such a policy to guarantee the fairness on revenue between the supplies. For this, the supply network plan should keep the capacity utilization ratio even for all the suppliers. But the production capacities are different and the distribution of molds is disproportional through suppliers, so the supply network plan is not easily established with simple arithmetic processes. Therefore, we developed the linear programming model with those target function and constraints minimizing the costs for holding inventory and penalty of delayed delivery, simultaneously guaranteeing the even capacity utilization through suppliers. The proposed model has been applied to real case and the evaluation for the planning result from the model would be followed in order to make sure that our model guarantee on extracting the supply network plan subordinated to the policy. Also we mention about further studies for improvement of the model.

Purpose - This paper aims to review cold chain management, especially in the pharmaceutical industry, to explore the cold chain process of delivering temperature-sensitive pharmaceutical products, and to identify areas for further development. Research design, data, and methodology - The paper, based on literature review and corporate analysis, reviews the development and status of the cold supply chain system, including its important role in the pharmaceutical industry. Results - Logistics in this field requires more stages than are typically needed. Due to the unique characteristics of the market, few companies can provide the services; currently, only few global companies with large networks and high technologies can afford to do so. Expanding pharmaceutical markets to meet global demand will require cold chain development, especially in "pharmerging" markets. Conclusions - Cold chain is a highly sensitive market in terms of products being carried within the chain that itself is a complex system. However, at the same time, it is a niche market with new opportunities. Hence, a sound cold chain infrastructure is needed to satisfy companies, governments, and customers for both commercial and public reasons.

In this study, we model a decentralized supply chain system which is managed by four types of centers, sequentially located: Retailer, Wholesaler, Distributor, and Factory Each center contributes to enhancing the performance of the supply chain system individually with its own local inventory information. Through experiments which are performed with a programmed simulation (like the MIT beer game), we investigate how the information lead time improvement in each center affects the whole system. And we show that the impact of the lead time improvement in the downstream, like retailers, affects more to the system than the one in the upstream, like factories, in a cost-effective way. Moreover, by using information lead time for each center, we analyze how much the extent of the improvement affects the whole system, especially for the total cost and the order level.

공급망 상 수출입에 관련된 비즈니스 영역과 규모가 큰 대기업은 전자적 데이터 기반으로 업무를 처리하고 있으나, 중소 규모의 기관 또는 민간 부분의 업무는 아직도 종이 서류를 사용하는 비중이 높아 비효율적으로 업무가 진행되고 있다. 최근 기업 환경을 보면 점차 환경친화적이고 저비용의 물류 관리에 대한 필요성이 증대되고 있다. 이에 본 논문에서는 전자문서 또는 종이 서류를 전자적 형태로 변환하여 보관하고, 필요 시 시스템에 접속하여 해당 문서를 활용할 수 있도록 하는 방식을 제안하고자 한다. 본 논문에서 정의한 비즈니스 프로세스 모델을 기반으로 한 공인전자문서보관소를 공급망 도메인에 적용한다면, 비즈니스 트랜잭션 상 교환된 전자문서나 개별적으로 보관하고 있는 종이서류를 전자적으로 변환하여 시스템에 저장할 수 있다. 이렇게 되면 개별 기관에서 보관해야 하는 번거로움이 줄어들고 또한 물리적 보관 장소도 필요가 없게 될 것이다. 즉 개별 기관 뿐 만 아니라 국가 전체적으로 비용적, 시간적 그리고 공간적 측면에서 효과가 있을 것으로 판단된다.

Purpose - The objective of this paper is to investigate the effect of asset specificity, the level of information sharing, the importance of information sharing, and an integrated collaborative environment on supply chain performance. Research design, data, and methodology - Data collection was implemented as follows: questionnaires were distributed to 250 companies that have business ties with Halla Climate Control Corporation. The empirical study to test our hypothesis was based on statistical analysis (using SPSS 18.0 and AMOS 18.0). The hypothesis of this paper is that the asset specificity variable has positive effects on the following variables: Level of information sharing, the importance of information sharing, and integrated collaborative environment. Moreover the variables, the level of information sharing, and the importance of information sharing are strongly influenced by the variable integrated collaborative environment, and these when combined, have an effect on the dependent variable, supply chain performance. We tested our hypothesized model utilizing path analysis with latent variables. Results - According to the results of our analysis, hypothesis H1, which tests whether there is a relationship between asset specificity and the integrated collaborative environment, is supported at the 0.01 level. Hypotheses H2 and H3 were also confirmed, and asset specificity had positive effects (+) on the level of information sharing variable. The importance of the information sharing variable was statistically significant at the 0.01 level. Hypotheses H4 and H5 posited that the integrated collaborative environment variable would have a positive effect on the level of information sharing; the importance of information sharing variable was strongly supported statistically, with a significant p-value below. Moreover, the level of information sharing (H6), and the importance of information sharing (H7) variables also had a statistically relevant influence on supply chain performance. As a result, existence of a collaborative system between companies would influence supply chain performance by strengthening real-time information access and information sharing. Thus, it is important to construct a collaborative environment where information sharing among companies and cooperation is possible. Conclusions - First, with rapid changes in the business environment, it becomes necessary for enterprises to acquire the right information in order to properly implement SCM. For successful SCM, firms should understand the importance of collaboration with supply chain partners and an internally built collaboration system, which in turn will better promote a partnership commitment with suppliers as well as collaborative integration with buyers. A collaborative system, as we suggest in this paper, facilitates the maintenance of a long-term relationship of trust, and can help reinforce information sharing. Second, it is necessary to increase information sharing over time via a collaborative system so that employees of the suppliers become aware of the system. The more proactive and positive attitudes are towards such a collaborative system by the managerial group, the higher the level of information sharing will be among the users. Successful SCM performance is achieved by information sharing through a collaborative environment rather than by investing only in setting up an information system.
