The successful implementation of green supply chain management(GSCM) practices requires a level of cooperation that can be difficult to conduct. Despite this challenge, limited scholarly attention has been paid to exploring how the implementation of GSCM practices can be effectively facilitated and enhanced through accumulated social capital with suppliers. Based on social capital theory, this study postulates that supplier network characteristics derived from social capital with key suppliers can be critical antecedents of GSCM, which in turn enhances the firm’s environmental performance. To test hypotheses, data were collected from 330 firms in 15 countries, and structural equation modeling was employed. Results show that GSCM improves environmental performance, and structural and cognitive social capitals of the supplier network act as antecedents and lead to GSCM implementation.

The purpose of this study was to analyze structural relationships with regard to the effect of customer integration, which is a type of integration in the supply chain, and market orientation of supply chain on the resulting change in the supply chain and management performance. The results of analysis in this study are as follows: First, customer integration and market orientation had a positive effect on reducing the flexibility and uncertainty of SCM. The decreased flexibility and uncertainty of SCM had a positive effect on non-financial performance, which also had a positive effect on financial performance. Second, customer integration and market orientation had a positive effect on financial and non-financial performance indirectly by decreasing the flexibility and uncertainty of SCM. Third, the effect of customer integration and uncertainty of SCM on the flexibility of SCM changed depending on the position in the supply chain; the effect was larger in the distribution group. The implications based on the analysis results are as follows: It is expected that the ability to deal with market changes in the overall supply chain is improved by laying the foundation for cooperation through establishing information infrastructure, including sharing information with trade partners and integrating systems, and implementing customer integration based on these achievements. It is also necessary to consider the business types and characteristics of individual companies in establishing information infrastructure.

The present study identified several antecedents that create perceived resistance to supply chain management (SCM) change. This work particularly emphasizes SCM change, which is notable given its central role in reacting market orientation and varied environmental and managerial conditions. A careful case study on a small and medium sized food production company in South Korea leads to the formulation of our framework including one second-order construct of ‘resistance’ as well as eight first-order constructs of ‘implementing the payment terms’, ‘balancing of business process’, ‘fear of responsibility’, ‘business sustainability transparency’, ‘past experience of failure’, ‘competence of work personnel’, ‘cooperation with third parties’ and ‘sharing personnel information with partner’. The hypothesized relation of first- and second-order construct was validated using survey sample data collected from 350 respondents who completed their questionnaire instrument. Results from confirmatory factor analysis revealed that nomological validity was established at statistical significance level by identifying six first order constructs of ‘implementing the payment terms’, ‘fear of responsibility’, ‘business sustainability transparency’, ‘past experience of failure’, a conbined construct of 'competence of work personnel/ cooperation with third parties’ and ‘sharing personnel information with partner’. The findings from our work are expected to provide important insights to the strategy for SCM risk management for small and medium sized company.

최근 선진국과 국제무역기구의 동향에 따르면, 9·11테러 이후 선진해운국들은 국제 사회의 주요 이슈로 등장한 선박, 항만, 항공, 철도 등을 포함한 국제물류 전 단계에서의 보안과 효율성 강화, WCO, 미국, EU가 주도하는 무역안전망 등을 확보를 위한 국제물류보안체제 구축을 적극적으로 추진하고 있다. 특히 최근 자율운항선박 및 위험물 운반선박 등과 관련된 사이버 보안 위험에 대한 관심과 관리의 중요성 부각되고 있음에도 불구하고, 여전히 단위 연결점에 대한 안전관리만 이루어지고 해상물류 전 구간에서 발생할 수 있는 보안 사고를 사전에 예방하는 관리가 이루어지지 못하고 있는 실정이다. 따라서 이 연구에서는 선박 보안사고의 실태 및 원인을 파악하여 선박보안 관리의 특성을 고찰함과 동시에 선박보안 관리 시스템의 취약성을 분석하였다. 그리고 이 연구는 해상공급사슬보안(maritime supply chain security)의 개념과 특징, 보안위험과 공급사슬의 취약성을 파악하고, 국제기구와 관련된 해상공급사슬보안제도와 주요국의 해상공급사슬보안 인증제도에 대한 현황 분석 및 시사점을 도출하여 해운물류회사의 경쟁력 향상을 위한 정책적 개선(안)을 제시하였다.

The purpose of this survey is to understand and identify how many organizations in Korea understand the importance and necessity of supply management policy. Most of supply management professionals have purchasing process(procedures) regardless of number of ones. However, they are generally not well aware of purchasing policy in supply management department in Korea. Advanced supply management organizations in U.S.A and main Europe countries recognize the necessity of supply management policy and pursue more reasonable one as a guideline of supply management in compliance with the characteristic of its business like national constitution. As the result of the 1st attitude survey and study on supply management policy, first, there is no big differences between public and private organizations to policy components. second, public organizations should have supply management policy considering a social standpoint a little bit differently from private ones. Third, most of supply management organizations have not comprehensive policy. Fourth, they are recognizing the importance and necessity of its policy, even though they don’t have it at the moment. However, in conclusion, through the survey, we find out that most of supply management professionals in Korea begin to recognize the importance and necessity of supply management policy to take a leading role in purchasing process(procedures. Furthermore, we recognize that related supply management experts and organizations including supply management professionals should continuously make an efforts to disseminate the importance and necessity of supply management policy

Recently, the need for asset management(AM) plan introduction to reduce increasing O&M cost with aging water facilities is on the rise. Therefore, asset inventory classification is necessary as the first step for AM plan construction. In this study, all assets of YW water treatment plant(WTP) were classified as 5 steps. In addition, specific code name was given to each asset which can increase compatibility in constructing the AM programs among WTPs. In the future, codes for attribute and status of asset will be allocated, which can facilitate proper AM operation.

This paper develops a two-echelon supply chain model with variable setup cost and environmental impact. A single-setup-multi-delivery (SSMD) policy is adopted to increase the efficiency of transportation in the supply chain in which it is assumed that the shipment lot size of each delivery is unequal and variable. Each delivered item goes through inspection process at the buyer’s end. After inspection, defective products are returned to the vendor for reworking process. Due to inspection process, end customers receives perfect quality items. Due to more transportations by SSMD policy, this model assumes carbon emission cost to help the world environment. An investment function is used to reduce total setup cost for the whole supply chain. Stackelberg leadership approach is utilized in this model to optimize the joint total cost of vendor and buyer. Finally, some numerical examples, sensitivity analysis, and graphical representations are given to illustrate more savings from existing literature.

Korea's modern waterworks began with construction of DDukdo water treatment plant in 1908 and has been growing rapidly along with the country’s economic development. As a result, water supply rates have reached 98.5% based on 2013. Despite multilateral efforts for high-quality water supply, such as introduction of advanced water treatment process, expansion of waterworks infrastructure and so on, distrust for drinking tap water has been continuing and domestic consumption rate of tap water is in around 5% level and extremely poor comparing to advanced countries such as the United States(56%), Japan(52%), etc. Recently, the water management has been facing the new phase due to water environmental degradation caused by climate change, aging facilities, etc. Therefore, K-water has converted water management paradigm from the "clean and safe water" to the "healthy water“ and been pushing the Smart Water City(SWC) Pilot Project in order to develop and spread new water supply models for consumers to believe and drink tap water through systematic water quality and quantity management combining ICT in the whole water supply process. The SWC pilot projects in Pa-ju city and Go-ryeong county were an opportunity to check the likelihood of the "smart water management" as the answer to future water management. It is needed to examine the necessity of smart water management introduction and nationwide SWC expansion in order to improve water welfare for people and resolve domestic & foreign water problems.

Fashion industry pressure on natural resources has grown dramatically as consumption grew in emerging countries and the principle of rapid change of fashions extended to mass market in western counties, at the same time supply chains expanded globally to countries with lower labor and environmental standards creating critical sustainability challenges. Meanwhile, sustainability has become a hot topic for consumers that hold brands responsible for sustainability performances along the whole supply chain. The paper traces developments in the fashion business commitment to sustainability over two decades, with a focus on the implication for SCM. Academic literature focuses mainly on partial issues, missing the overall picture, the interaction among a complex set of factors, and to account for the role of past decisions and mistakes on current SSCM (sustainable supply chain management) strategy developments. The time span considered captures sustainability awareness in the fashion business which is in its statu nascenti (nascent state) and the trial and error process that led to progressive refinements of both means and ends. The paper provides an extensive review of academic articles, business reports, technical documents, regulations and direct information from the field and identifies five key lessons learnt in this process that influence current fashion business strategies in sustainability and SCM.

Considering the supply system and operating cost of enterprises which are in the supply chain as the main index, this paper establishes a supply chain evaluation model, and utilizes Arena building stimulation model of the supply chain which considers manufacturing enterprises as the core of supply chain. This model designs a generic simulation model of the supply chain including multi-level distributors and suppliers. And the model analyzes a representative example of business process, one of the enterprises in Shandong.

In this paper, a System Dynamics(SD) computer simulation model has been developed to assess the effects of developing and providing an alternate water source. A water service index was also developed to estimate the level of overall customer satisfaction on water supply service. Data from the Busan water supply service and the Korea Development Institute regarding the Nak Dong river bank storage development were utilized during the modeling processes. Some important indicators of the system under study were analyzed by the simulations of development of the alternate water source for Busan. The developed SD model and the water service index can be further utilized as a tool that can assess the extent and timing of an additional service improvement project.

Many manufacturing industries need more efficient organization since the customer expects a greater response to orders Due to this increased expectation, a supply chain management (SCM) has become one of the most important methods of competitive advantage in business today. This study has developed a simulator for the supply chain management problem. The simulator designed to help determine considering to the capacities and the costs of production and distribution facilities. The simulator developed using commercial simulation tool ARENA and the results of computational experiments for a simple example were given and discussed to validate the developed simulator. The simulator can be used to decide an realistic production-distribution planning in the area.

As customers' demands for diversified small-quantity products have been increased, there have been great efforts for a firm to respond to customers' demands flexibly and minimize the cost of inventory at the same time. To achieve that goal, in SCM perspective, many firms have tried to control the inventory efficiently. We present an mathematical model to determine the near optimal (s, S) policy of the supply chain, composed of multi suppliers, a warehouse and multi retailers. (s, S) policy is to order the quantity up to target inventory level when inventory level falls below the reorder point. But it is difficult to analyze inventory level because it is varied with stochastic demand of customers. To reflect stochastic demand of customers in our model, we do the analyses in the following order. First, the analysis of inventory in retailers is done at the mathematical model that we present. Then, the analysis of demand pattern in a warehouse is performed as the inventory of a warehouse is much effected by retailers' order. After that, the analysis of inventory in a warehouse is followed. Finally, the integrated mathematical model is presented. It is not easy to get the solution of the mathematical model, because it includes many stochastic factors. Thus, we get the solutions after the stochastic demand is approximated, then they are verified by the simulations.

It is very important the collaboration and risk management of supply chain between the parent company and its partners in the supply chain risk management(SCRM). It was known that the SCRM approach is very different between a large enterprise and a small and medium-sized enterprise. This paper deals with the suggestion about SCRM structure for a small and medium-sized enterprise. This SCRM structure consist of risk identification, risk assessment, and risk mitigation. We expect that this SCRM structure promote the collaboration between a parent company and its partners to alleviate the supply chain risk.

Studies have shown that the future of the wine market rests on the effective and efficient changes in technology to the supply chain used by most of the major global players. In today’s wine industry, companies are faced with the ever-shifting demand for their products, strict regulation and increasing price competition. Even at that, mature companies in the wine industry are succeeding by scaling up production, streamlining their supply chains, expanding into new geographic areas, implementing more efficient processes, cleverly marketing products, and focusing on ever closer relationships with suppliers, partners and customers. However, this paper looks at supply chain challenges in the wine industry from a global perspective presented in the inbound, manufacturing and outbound processes as well as offer effective solutions in order for companies to gain a competitive advantage and succeed on a global level.

Since manufacturing and supplying corporations today come to view their practice of SCM as important, it becomes essential to analyze and control the structural relationship between the information sharing among corporations and the performances resulting from their practice of SCM. It is thus the purpose of this paper to examine the factors that may prompt corporations to implement SCM by means of analyses into the relationship between information sharing and practice of SCM which corporations should lay stress on as well as the relationship between financial and non-financial performances of corporations. The findings of the study can be summed up as follows: First, as for the relationship between information sharing among and practice of SCM by corporations, information sharing among corporations turned out to affect such factors of implementing their SCM as trust, commitment mutual dependence. Consequently, corporations are requested to endeavor to implement SCM itself faithfully if they really aim to achieve their performances by practice of SCM and, at the same time, to make efforts to obtain understanding and support for information sharing among themselves. Second, from the analysis of the relationship between SCM and financial as well as non-financial performances of corporations, it was found that trust, a factor of SCM practice, had influence upon non-financial performances of corporations, but not upon their financial performances, while commitment and mutual dependence affected both financial and non-financial achievements of corporations. Therefore, it was made clear from the analysis that the decision and systematic control of SCM activities which best suit to a corporation play an important role in improving its financial and non-financial performances, because they greatly depend on the implementing extent of SCM factors such as trust, commitment and mutual dependence among corporations.
