  • This paper deals with the selection of a proper dispatching rule for an one-process Job scheduling that follows a particular distribution of an order production. That is, it makes a distribution on an order per unit period and applies to simulation model that uses it. This study consists of two purposes either seeks adequately production scheduling using priority rule or seeks extension of the facilities that increase current production efficiency through computer simulation in scheduling.

  • There has been a lot of research on and release of commercial systems that enable evaluation and visualization of construction methods. These have enabled the selection of good construction plans. However, the process in which engineers build 3D geometry, formulate a schedule and eventually synchronize them is still a time-consuming process. Changing any aspect of the geometry or the schedule and re-linking them is also time-consuming. Therefore, the engineers may compromise on getting the best solution. This paper describes a technique to automate the generation of multiple sets of schedules, quantity takeoffs and 4D visualization from a single 3D model.

  • In this study, the effect of platform selection attributes on customer satisfaction by mediating supplier trust for agrifood platform users was analyzed. The sub-variables of the selection attribute were classified into diversity, convenience, information, commerciality, and interactivity. The collected 190 questionnaires, SPSS v24.0 and Process macro 4.0 were used for empirical analysis. As a result of the analysis, first, it was found that information, commerciality, and interactivity affect supplier trust in a positive direction, and diversity and convenience do not affect supplier trust. Second, it was confirmed that supplier trust had a significant positive effect on customer satisfaction. Third, convenience, information, commerciality, and interactivity were found to affect customer satisfaction in a positive direction, and diversity did not affect customer satisfaction. It was tested to mediate between informational, commercial, interactivity and customer satisfaction. These results suggest that the platform's informativeness, commerciality, and interactivity can increase customer satisfaction by increasing supplier trust. As a follow-up study, it is recommended that the analysis of moderated mediating effects by the conditional process model including moderating variables or research to discover third mediator(s) other than the supplier trust used in the study is needed.

  • A weaving machine for texture industry uses a lot of needles and the nib of these needles is necessary to be kept with sharp edge. The re-grinding of the needle by a special purpose of the grinding wheel can be selected for achieving this aim. This study focused on the manufacture and performance assessment the special grinding wheel. A forming mold for the grinding wheel was designed and a sintering process for furnace process control was established. Manufactured wheels were tested for determining suitable grade of the wheel. The selection of optimal grinding conditions was achieved by a response surface method and a genetic algorithm.

  • Recently the business transformaton of a company is achieved through the business process re-design and total quality management concept. This paper focused on the decision of the critical measurement point(CMP) for maximizing the effectiveness of the business process reengineering. In general, the types of business processes can be classified into two kinds, serial processes with IPO(input/process/output) type and non-serial processes with workflow type. The traditional method of selecting the CMP relies on the experiences and intuitions of the process owners. We suggest a mathematical method for more objective selection of CMP by using Dynamic Programming.

  • The purpose of this study is to provide an integrated process control system for plasma etching. The control system is designed to employ neural network for the modeling of plasma etching process and to utilize genetic algorithm to search for the appropriate selection of control input variables, and to provide a control chart to maintain the process output within a desired range in the real plasma etching process. The target equipment is the one operating in DRAM production lines. The result shows that the integrated system developed is practical value in the improved performance of plasma etching process.

  • This paper deals with development of expert process planning system which automatically generates process plan for manufacturing parts of injection mold. The specific domain of study is two-plate injection mold without support plate. Decision making rules for selection of machining processes machine tools, cutting tools and for determination of sequence of machining operations are acquired by interview of skilled process planner. The developed expert process planning system is programmed by using expert system shell CLIPS on the IBM PC/AT. The proposed system works well to real problems.
