A web-based program life-cycle management(PLM) system is introduced to implement the system engineering processes and to provide the development teaceability online. This information system aims for the realization of essential system engineering management techniques currently applied to the space launch system development program including management of configuration and data based on the work breakdown structure(WBS), WBS, bill of materials and properties. The system enhances communication and gives access to the development data with relevant information such as data-to-data relation and approval status/history through the web, and preserve all of the development data throughout the program life-cycle. Further improvement of the system is planned to implement the program managrment pricesses and to provide integrated information useful for the programmatic decision making.

Sourcing Simulator is specialized form of software capable of providing great insight into merchandising decision making. It is relatively easy to learn and operate by reading the help menus, experimenting with inputs, and critically analyzing outputs. 1 see that it has great potential in a training program for new merchandisers to help them absorb the complexity of the numbers they must effectively use. The Sourcing Simulator, Version 1 that accompanies my textbook, Merchandising: Theory Principles, and Practice, 2nd ed. is the least complex version available. Two versions are available from [TC]2 - Retail version and The Retail/ Manufacturing version. The Retail Version is very similar to the Version 1. The Retail/ Manufacturing Version includes analysis of processes and costs in the manufacturing process as well as the merchandise planning component that we have discussed here. Sourcing Simulator is developed at North Carolina State University by Dr. Russ King, and available from Textile Clothing Technology Corporation $[TC]^2$, Cary, North Carolina.

Purpose : PBL is a teaching method to learn problem-solving process. Present study was to investigate the predictors of academic achievement when PBL is applied to students of physical therapy. Method : We Performed in-depth interviews and analyzed using the qualitative analysis by randomly assigning 5 of twenty four students who attended the class. Result : The results are classified into two categories and six sub-subjects. Based on two system of classification, PBL showed the learning effect through problem-solving methods because students directly participated in these processes. Also, students need to clearly comprehend communication method and decision-making process in order to progress the class smoothly. Conclusion : Therefore, futher studies will be continuously needed on how we apply PBL to various curriculums of physical therapy.

Private brands play an important role in formulating the marketing strategies of fashion goods. Merchandisers of Korean department stores are now realizing that the effective marketing of private brands can increase customers store loyalty as well as store profitability. Thus, it is important to better understand customer's decision making processes underlying the purchase of private brand apparels. However, Little research had been undertaken to examine integrated factors influencing purchases of private brand apparel. Therefore, the objective of this study is to propose a model of purchasing intentions of private brand apparel. This study pays attention to (1) perceived value, (2) familarity, (3) store image, (4) differenciated needs, (5) perceived risk, and (6) perceived quality variation of private brand. The proposed model supports all hypotheses presented in the paper. Purchase intentions of private brand increased as perceived money, familiarity, positive store image of private brands, and satisfaction of individuals differentiated needs increase. Furthermore, perceive value of private brand increased as perceived risk and quality variation of private brand increased.

We introduce a two-stage game theoretic model to support decision making processes for product Positioning and pricing in competitive environment. In the first stage, firms decide on entry and product position, in the second stage, firms compete with price. 'Alpha rule' is used as a choice model. Demand parameters of the choice model are estimated by conjoint analysis. We investigate conditions for the existence of Nash price equilibria in the pricing game. Nash equilibria in the entry and positioning game are produced using a concept of stable sets. An example of the online game industry in Korea is examined.

Workflow is a collection of tasks organized to accomplish some business processes. It also defines the order of task invocation or conditions under which task must be invoked, task synchronization, and information flow. And activity based costing(ABC) provides accurate cost information for decision making. In ABC systems, costs must be separable into cost pools each of which corresponding to a single cost driver. These two systems are closely related to each other. But recent research deals with workflows and ABC systems separately. Thus, this research proposes an extended workflow model which is expressed cost information using activity based costing.

With the increase of global competition and the reduction of the lifecycle of business process, most leading companies begin to adopt BPO(Business Process Outsourcing), by outsourcing the whole or part of their business process to external service providers and focusing on their core capability, in order to enhance their core competency, In adopting BPO, it is an important decision-making issue that which part of process should be outsourced. So identifying core/non-core process among the business processes is a prerequisite for managing corporate capability and performance of outsourcing. In this study, by focusing on knowledge intensity and degree of informatization of the business process that are important factors in adopting BPO, we have analyzed the current status of BPO adoption of domestic firms and proposed several guidelines for adopting BPO.

This paper suggests an approach to quantitative evaluation of a manufacturing flexibility in automated manufacturing systems. The flexibility of a cell is newly defined and evaluated in use of the environmental change factors which may influence flexibility for satisfying a manufacturing performance objective. The number of machines, the number of operations, machine breakdowns and processing times are considered for this cell flexibility measure. The cell flexibility measures the extent that the cell utilizes the processes to acquire high throughput. Simulation program written in SLAM System was used to help measure cell flexibility. The proposed cell flexibility measure provides a prediction of the influence of the factors on throughput performance, and applies in case of comparison of existing system and a new system, changes in operation conditions of a cell, and comparison of rival machines. Therefore it can be used as decision making criteria for system justification.

This study presents the decision of priority for optimal design guide to improve disassembly process. Disassembly process is divided into recognition, transfer and disassembly of assembly point and recognition, transfer and remove of grasp point. Significant influential factors are derived from analyzing the above process. And those factors are used for making the check list to evaluate the properties of parts in each process. Furthermore, the weight with considering disassembly process is also used to determine weight of each process. On the base of the above sequence, qualitative score of disassemblability of each process that is enabled to compare different disassembly processes can be acquired. Ultimately the score helps to decide the priority of design guide for disassembly process.
