There is the uncertainty of demands at each retailer in the supply chain. To satisfy customers' demand, retailer must have enough inventory. Nevertheless, stockout is occurred for some retailers. A lateral transshipment policy can be effectively used to deal with stockout. The new lateral transshipment policy, referred to service level adjustment (SLA), is suggested. The difference between SLA and previous policies is the integration of an emergency lateral 'transshipment with a preventive lateral transshipment to efficiently respond customers' demand in the proposed policy. Additionally, the service level to decide the quantity of products is considered. Simulation experiment is executed to treat stochastic factors in the two-echelon supply chain. The proposed policy can reduce total cost and is more effective to the change of demand, penalty cost, and ordering cost than the currently used policies.

The demand for services using digital technology is constantly increasing as new developments in digital consumer electronics and the Internet are made. This is especially true in terms of the demand for IPTV utilizing high speed Internet networks. Research on IPTV threats is important for facilitating financial transactions via IPTV and preventing illegal use or copying of digital content. Thus, this paper analyzes IPTV threats via the IPTV value chain. That is, the distribution system for IPTV service is analyzed along with the components of the value chain and corresponding IPTV security requirements or security technologies, in order to perform a threat analysis and research suitable for the IPTV service environment. This paper has a greater focus on the value chain of the IPTV business than the approach in previous research, in order to analyze security requirements and technologies that are more applicable to the business environment.

This paper analyzes a discrete-time bulk-service queue with probabilistic bulk size, where the service process is interrupted by a Markov chain. We study the joint probability generating function of system occupancy and the state of the Markov chain. We derive several performance measures of interest, including average system occupancy and delay distribution.

In this paper, we surveyed the actual utilization condition of chain stores of franchise systems and the customers' consciousness on chain shops and non-chain restaurants. The survey was conducted on 459 people either living or working in Pusan area and aged more than 4th grade in elementary school without sex distinction. The data analyses were made by way of frequency, percentage, Spearman rank correlation and Chi-square using dBastat 1.0 package of PC. The results of the survey are as follows. The survey indicates that respondents have the most experience of visiting chicken, hamburger, and pizza chain shops. Although the survey on the degree of preference between chain shops and non-chain restaurants indicates that men prefer non-chain restaurants and women prefer chain shops, the results are not so significant to conclude that there is a preference regardless of sex (N. S.): By ages, students and young group prefer chain shops and the aged group prefer non-chain restaurants (p< 0.05). The survey indicates that chain shops are proffered because of sanitary, quality, taste of foods and are not proffered because of simple menu and expensiveness. The survey indicates that non-chain restaurants are preferred because of distinctive taste of each restaurant and comfotableness, and are not proffered because of unsanitary and unkindness.

Supply Chain Management is the process of planning, implementing and controlling the operations of the supply chain to satisfy customer requirements as efficiently as possible. It spans all movements and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. Korean Standards Association claims the Supply Chain Quality Management(SCQM) as a win-win model of organizations among the supply chains for the best product/service quality to final customers. The SCQM is focused on quality of product/service and will do much for improving manufacturing performance between customer and suppliers. Consulting-teams make every effort to design suitable solution for constructing solutions and improving the performance. This study is to analyze the performance of SCQM consulting, from July of 2007 to June of 2008, and would provide some guidelines to design the optimal consulting models and develop guidebooks.

This study focuses on green human resources management (GHRM), which is currently a strategic issue in almost every service or manufacturing company, including courier service SMEs in Indonesia. This study intends to analyze the relationship between GHRM and supply chain organizational learning (SCOL), supply chain performance (SCP), and business performance (BP) still rarely studied. The population encompasses all courier service SMEs in the Special Province of Yogyakarta (DIY) and East Java, Indonesia. The study targets courier service SMEs that meet certain conditions; 130 SMEs responded from the target of 200 SMEs. Partial Least Square statistical technique is used. The results show that conventional HRM practices are increasingly being abandoned by courier companies in Indonesia, particularly in Special Province of Yogyakarta and East Java. Although GHRM has a negative and non-significant effect on BP, GHRM has a positive effect on SCOL and SCP. SCOL has a significant positive effect on SCP and BP. Furthermore, SCOL mediates the relationship between GHRM and SCP and SCOL mediates the relationship between GHRM and BP. Likewise, SCP has a positive effect on BP. In addition, SCP mediates the relationship between GHRM and BP. SCP also mediates the relationship between SCOL and BP.

Purpose : With the proliferation of O2O platform services that combine offline and online services, many startups are fiercely competing to lead services in the O2O service market. While the prospects for growth in the O2O service market are optimistic because of the close convenience to life, startups can achieve corporate performance only through close cooperation and partnership with suppliers. The purpose of this study is to verify the effect of O2O-based startups' and suppliers' cooperation in supply chain management on SCM performance through supply chain partnerships and startup satisfaction with suppliers. Research design, data, methodology : Data were collected from O2O service-based startups and hypotheses were verified through frequency analysis, exploratory factor analysis, reliability analysis, confirmatory factor analysis, feasibility analysis, and structural equation path analysis. In addition, the mediating effects of supply chain partnerships and startup satisfaction on suppliers were verified. Results : As a result of this study, IT utilization of the O2O startup cooperation method affects the financial perspective of supply chain partnership and SCM performance. The contract implementation of the cooperation method had an impact on the financial and innovation growth perspectives of the SCM performance, and the communication of the cooperation method had an effect on the supply chain partnership, startup satisfaction in the supply chain, and the innovation growth perspective of the SCM performance. Supply chain partnerships had an impact on the financial, innovation growth, and customer perspectives of SCM performance and startup satisfaction within the supply chain had a significant effect on innovation growth and customer perspectives. Conclusions : The implications of this study identified the factors that can improve SCM performance through the cooperation method of O2O startup, supply chain partnership and startup satisfaction with suppliers, and it is significant that the causal relationship was identified by the structural model through the supply chain cooperation factors derived by characteristics. Based on the empirical results, as the services of O2O startups grow, it is expected that empirical research and practical activation of academia should be considered as important in the cooperation of the supply chain.
