A Case Study on the Application of Decomposition Principle to a Linear Programming Problem
Yun, In-Jung ; Kim, Seong-In ;
IE interfaces, volume 1, issue 1, 1988, Pages 1~7
This paper discusses the applicability of the decomposition principle to an LP (Linear Programming) problem. Through a case study on product mix problems in a chemical process of Korean Steel Chemical Co., Ltd., the decomposition algorithm, LP Simplex method and a modified method are compared and evaluated in computation time and number of iterations.
A statistical analysis of magnetic field intensities for estimating the size and orientation of the petroleum deposit
Jeon, Deok-Bin ;
IE interfaces, volume 1, issue 1, 1988, Pages 9~15
A statistical analysis for detecting deviations from normal magnetic field intensities, caused by the introduction of magnetite materials into man-made fissures and cracks at subsurface levels is presented. For detecting such deviations it turns out the comparison of two different field measurements measured at two different sites far from each other is more efficient than the study of the only measurement by the univariate and bivariate time series analysis.
A Study on Optimal Composition for Composite Solid Propellant under Multiple Criteria
Jeong, Byeong-Hui ; Kim, Gi-Bae ;
IE interfaces, volume 1, issue 1, 1988, Pages 17~26
This paper describes a nonlinear goal programming approach to the optimal composition of composite solid propellant taking multiple characteristics into consideration synchronously. The nonlinear goal programming model with response functions, restrictions and the optimal value of each characteristic is developed using Scheffe's "Experiments with mixtures" and preference weighting system. Objective functions are described based on process, performance and assurance characteristics. The systematic approach to optimal composition in this study is proved efficient through a CTPB-AL-AP propellant which is one of composite solid propellant systems.
Analysis of facility expansion plan using simulation technique
Yun, Sang-Gyu ;
IE interfaces, volume 1, issue 1, 1988, Pages 27~37
In the multi-stage and multi-process plant, it is not an easy task to describe the interrelationships among each process and facility. The purpose of this simulation study is to analyze the effect of additional facilities on productivity in a steel mill. The simulation was performed using SLAM Simulation Language for Alternative Modeling. The results of this study was used by the plant engineers in making decisions on the expansion of the plate mill. The prediction of which process would cause bottle-necks enabled the plant engineers to invest most effectively.
AN EVALUATION OF A SUPERMARKET MANAGEMENT VIA A COMPUTER SIMULATION
Park, Yang-Byeong ;
IE interfaces, volume 1, issue 1, 1988, Pages 39~48
Simulation is one of the most widely used techniques in operations research and management science, and by all indications its popularity is on the increase. There have been several impediments to its even wider acceptance and usefulness. This paper presents a simulation study for evaluating lane operation and determining parking space for customers in a supermarket using a SLAM network simulation model. The results for the simulation are analyzed using statistical methods.
Determination of Container Terminal Operating System Using Computer Simulation
Jang, Seong-Yong ; Park, Jin-U ;
IE interfaces, volume 1, issue 1, 1988, Pages 49~62
This paper deals with the case study that determines the best operating system of a container terminal using computer simulation techniques. For the simulation, SIMAN simulation language is used. The simulation model developed circumvents the dimensional restrictions imposed by the SIMAN package. Non-terminating simulation experiments are conducted for the 90 days' work on the basis of operation practices of real terminals.
A Study on Computer-Generated time Standard Calculations with Applications
Yu, Byeong-Nam ; Sin, Hyeon-Pyo ;
IE interfaces, volume 1, issue 1, 1988, Pages 63~72
Since many small and medium sized enterprises in Korea have lack of funds to install a commercial computer packages for work standards and work scheduling. This study has been attempted to develop the computer-generated package to ease those problems. The system consisted of three major parts. The first part is a work measurement program applying W.F.(work factor) predetermined time standards for work standards. The second part is a work scheduling program which calculates each operator's machine and job allocation. The last part is a control program for the production outputs and the machine utilization monitoring. The system is programmed by dBASE III for the IBM-PC compatibles for the sake of user's conveniences.
Development of a Procedure for Feasibility Analysis of New Hospitals
Park, Chun-Yeop ;
IE interfaces, volume 1, issue 1, 1988, Pages 73~83
The purpose of this paper is to present a procedure for feasibility analysis of new hospitals. The major steps of the procedure proposed consists of determination of location for a new hospital, analysis of the community served, facilities planning, estimation of capital requirements and financial analysis. Technical details of the necessary analyses are covered by providing relevant information most of which is readily available in Korea. The procedure proposed in this paper can be applied not only for the case of the general hospital but also for the case of the clinic.
An Ergonomic Approach for Identification of Potential High Touch Products
Kim, Yong-Won ; Kim, Chung-Se ; Lee, Myeon-U ; Lee, In-Jae ;
IE interfaces, volume 1, issue 1, 1988, Pages 85~99
High Touch product is characterized by shorter life cycle together with specification/integration of existing function in order to capitalize the rapidly emerging high technology. R & D strategy for a development of High Touch product generally emphasizes two aspects ; Industrial Design (ID) and Ergonomic Design (ED). However, working knowledge on ED of a systematic identification of potential High Touch products is not readily available. The purpose of this study was three-folded : (1) To emphasize the fact that greater efforts should be geared to ED in High Touch design ; (2) To develop an ergonomic approach based on analysis of implicit human needs that identifies potential area of High Touch ; (3) To bubble with new and probable High Touch products in home electronics that actually demonstrate the validity of this study.
