In the weapon system development/operation stage, the goals of RAM activities are to support the cost effective performance optimization in design and operation supports. In the study, the main contents are as follows; 1) To establish the operational concept and circumstance of the subsequent tank, the combat/operation scenario, the operational mode summary and mission profile for subsequent tank development are analyzed. 2) To evaluate the administrative and logistics down time for subsequent tank, the prefigured logistics circumstance and maintenance system are analyzed. 3) To calculate the RAM object values, a mathematical model for the user are developed. 4) To examinate the propriety of the RAM object values, the combat readiness are reviewed. The obtained RAM object values are provided to predict and analyze for the combat readiness, staying power, mission reliability, equipment availability and the logistic support capability.

The purpose of this study is to clarity the effect of job autonomy, innovative work behaviors and perceived organizational support on organizational performance. To attain this goal, mediation analysis, moderation analysis and moderated mediation analysis were performed. 198 valid questionnaires from China Tianjin City's logistics enterprises were analyzed with SPSS Macro program. The results indicated that: (1) perceived organizational support's moderating effect existed in the relationship between job autonomy and innovative work behaviors, (2) innovative behaviors' mediated effect existed in the relationship between job autonomy and organizational performance, (3) perceived organizational support's moderated mediation effect is existing in the relationship between job autonomy, innovative behaviors and organizational performance. That is to say, the strength of the mediated effect decreased along with levels of perceived organizational support: stronger job autonomy relationship when perceived organizational support was weak.

While the Military Logistics System and its Outcome Quality have been Emphasized, User Unit's needs on Interaction Quality Begin to Appears as a New Subject in Logistics Field. Interaction Quality of Supply, Maintenance and Foods Among Logistics Functions Influenced much more to User Unit's Satisfaction. Especially Maintenance on Satisfaction was Prominent. Analyses of the Survey and Interview with Field Employees Supported the Results, and the Characteristics of Maintenance Function also Accord with those. Moreover, the Service Maintenance Employees, who Showed Higher Job Satisfaction Among Three Functions, led to Higher Satisfaction of User Units.

This paper is concerned with the development of a GIS-based distribution system with service consideration. The proposed model could be used for a wide range of logistics applications in planning, engineering and operational purpose for logistics system. This research addresses the formulation of those complex prob1ems of two-echelon logistics system to plan the incorporating supply center locations and distribution problems based on GIS. We propose an integrated logistics model for determining the optimal patterns of supply centers and inventory allocations (customers) with a three-step sequential approach. 1) First step, Developing GIS-distance model and stochastic set-covering program to determine Optimel pattern of supply center location. 2) Second step, Optimal sector-clustering to support customers. 3) Third step, Optimal vehicle rouse scheduling based on GIS, GIS-VRP In this research we developed GUI-tree program, the GIS-VRP provide the vehicle to users and freight information in real time. We applied a set of sample examples to this model and demonstrated samp1e results. It has been found that the proposed model is potentially efficient and useful in solving multi-depot problem through examples. However the proposed model can provide logistics decision makers to get the best supply schedule.

The purpose of this study is to compare and derive the importance of motivating factors for start-up when deciding to start a business in the logistics and trading industries, and to compare, derive, and identify which motivating factors have an important influence on the start-up decision. In this study, 4 high-level factors such as career factors, policy/institutional factors, environmental factors, and economic factors and 12 low-level factors were derived from those four factors. Based on this, a questionnaire was distributed to established and prospective entrepreneurs, and the results were analyzed using the AHP (Analytic Hierarchy Process) technique. Manufacturing companies recognized the individual's capabilities and government support for them as important. Beside, service companies recognized the industrial environment that could generate economic benefits as important. Although there are differences in perception by group, it can be seen that factors that are recognized as important within each group have connectivity and show the same directivity.

This study aims to draw meaningful points from the Chang Po Go period in which Chang Po Go, who established an integrated logistics system while operating on the seas of three nations including Japan, China, and Shilla by taking Chunghaejin, Shilla, as a base of operations in the 9th century, and to discover the need for the construction of the logistics system in northeast Asia. Also, the study intends to propose strategies for contemporary application of the logistics system used during the Chang Po Go period, based on the modern logistics concept. As a result of specifically reviewing the lesson from the Chang Po Go period, which created a paradigm for a new cooperation in logistics, the leadership of the CEO, who is prepared with the long-term vision of Chang Po Go, the implementation of an integrated system for logistics activity, and the political support of the government for private companies, will initiate a bright outlook for the construction of the logistics system in northeast Asia, amid the growing need for cooperation in logistics among the three northeast Asian countries. In this era in which northeast Asia is emerging as the center of the world economy, the cooperative model in the logistics field, which transcended the border of Chang Po Go, who built a maritime logistics network in the 9th century, will help implement a cooperative logistics system in the northeast Asian region.

Companies are facing challenges to have high competitiveness because of continuous oil price rising and CO2 emissions regulations. Thus, companies are trying hard to construct effective logistics and operation system to achieve high customer service quality and saving cost. Also the ec-friendly idustrial complex is needed. Busan is in process to construct GILC(Global Industry Logistics City) in west Busan province to achieve high competitiveness and support lack of industrial complex. To construct this kind of logistics industrial complex, it needs logistics system through proper policy and freight transportation co-operation. Especially, efficient management through logistics hierarchy construction in industrial complex is very important for low cost and eco-friendly point of view. Therefore, this paper aims to analyze logistics system and suggest operation model to present logistics complex construction base data.

The market for commercial open source software (OSS) has been rapidly growing with the proliferation of OSS. One way to commercialize OSS is the support model, which has been adopted by leading OSS firms such as Red Hat and JBoss. Despite the growing interest in OSS commercialization, little research has provided OSS support providers with a pricing guideline. In this paper, we examine the optimal pricing strategies for OSS support providers. Our benchmark is a monopoly case in which we investigate a startup software vendor's incentive to choose the OSS support regime over the proprietary one. Then we extend the model to a duopoly case in which OSS under the support regime competes against proprietary software. We characterize the conditions under which the OSS support model is viable under competition. We believe that our results offer insights to the OSS vendors who consider commercializing their OSS with a support model.
