A Study on the Transition Probability Matrix set from a Transfer Line Model
No, Hyeong-Min ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 1~9
In this study, two stage transfer line with limited repair capability is modeled to formulate optimal dynamic repair priority policy. The method of Markov Chains is used to analyze the analytical model of this line. An efficient algorithm is developed, utilizing the block tridiagonal structure of the transition probability matrix, to obtain the steady state probabilities and system performance measures, such as the steady state production rate of the line and the average in-process inventory in the interstage buffer.
Quality Inspection Plans for Products Sold under Warranty
Kim, Yeong-Ho ; Lee, Chang-Hun ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 11~18
Three types of warranty policies are considered. They are (1) free warranty policy for repairable products, (2) free warranty policy for nonrepairable products, and (3) rebate warranty policy. Under each warranty policy, a single sampling attribute plan with non-destructive testing is considered. A sampling plan is characterized by the sample size and the acceptance number. For each case, characteristics of an optimum sampling plan are discussed and determined, which minimize the warranty cost and the corresponding quality control cost within the assigned producer's risk and consumer's risk.
Optimal Numbers of Repeat Inspections with Decreasing Detection Probability
Kim, S.B. ; Bai, D.S. ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 19~27
Optimal numbers of repeat inspections are obtained for a single inspector who has a fixed probability of detecting a nonconforming item on each inspection and will continue to inspect until further inspection is not warranted when comparing the expected increase of total gain with the inspection cost. It is assumed that the detection probability decreases as the number of repeat inspections increases, and that the lot to be inspected contains an unknown but Poisson distributed number of nonconforming items.
An Integrated Production-Inventory Model
No, In-Gyu ; Park, Sang-Don ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 29~37
This paper studies a production-inventory model which unifies the inventory problem of raw materials and the finished product for a single product manufacturing system. The integrated production-inventory model is formulated wth a nonlinear mixed integer programming problem. An algorithm is developed by utilizing the finite explicit enumeration method. The algorithm guarantees to generate an optimal policy for minimizing the total annual variable cost. A mumerical example involving 15 raw materials is given to illustrate the recommended solution procedure.
An Integrated Production-inventory Model for a Single Product System with Jointly Replenished Raw Materials
Kim, Gyeong-Mo ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 39~45
This paper is concerned with the integrated production-inventory model with jointly replenished raw materials. A search procedure is presented to determine the economic batch size for the finished product and the economic order quantity for each raw material simultaneously. A case study is given to back up this work.
A Two-Product Three-Facility Production Planning Model in a Combined Parallel and Serial System
Sung, C.S. ; Lee, B.J. ; Lee, Y.J. ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 47~56
This paper considers a two-product three-facility production planning model, where facility 1 produces product 1 to satisfy its own market requirements and supplies input to facility 2, and facility 2 requires another input from facility 3 (outside supplier). The objective is to determine the optimal production amount in each period in order to satisfy the dynamic demands on time, which minimizes the total cost of production and storage. The set-up cost is incurred jointly from the multi-facility operations.

Jo, Gyu-Gap ; O, Su-Cheol ; Yang, Tae-Yong ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 57~73
Group scheduling problem in a multi-stage manufacturing system is reviewed and two heuristic procedures for minimizing the makespan are developed by employing the methods of flow shop sequencing heuristics with a slight modification. The comparisons among the five heuristics, three previously reported heuristics and two heuristics suggested by this study, are made on different problem sizes. The computational results indicate that NEH-GS method gives better group schedules than the other heuristics tested, but its computation time increases rapidly as the problem size increases. On the other hand, CDS-GS method provides relatively good group schedules with less computation time compared with NEH-GS method.
Multi-Stage Group Scheduling with Dependent Setup Time
Song, Yeong-U ; No, In-Gyu ; Kim, Man-Sik ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 75~85
The application of GT results in the mass production effect to multi-product, small lot-sized production. Group scheduling, which is operations scheduling based on the GT concept, is analyzed in a multistage manufacturing system. But the research has been limited in independent setup time models. A heuristic algorithm has been developed to minimize the mean flow time when setup times are dependent to sequence of group in multistage. For evaluation of the heuristic algorithm, the solution of heuristic algorithm is compared with that of random scheduling. The result of comparison indicates that the proposed heuristic algorithm provides good solutions with relatively fewer computational effort.

Lee, Myeon-U ; Jeong, Gyeong-Ho ; Han, Seong-Ho ; Lee, Geung-Se ; Lee, Chun-Sik ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 87~99
The purpose of this study is to analyze the changes in centers-of-gravity (COG), acceleration and body posture and their associated effects both on EMG and on the maximum capability of weight lifting during Clean & Jerk and Snatch motions. Displacement, velocity, acceleration of joints were obtained from film analysis. Also levels of exertions on 11 major muscle groups were obtained from EMG analysis during a lifting cycle. The EMG data were measured from Telemetry System which is useful in field experiments. Magnitude and direction of force, change in center-of-gravity were extracted from COG data which were measured from force platform. The results of this study can be to be useful both to coaches and to athletes in weight-lifting.
Estimation of Availability for Multi-Module Software Systems
Kim, Yeong-Hwi ; Kim, Jung-Hwan ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 101~111
This study deals with problems of estimating the availability of the multi-module software systems. The result presented in this paper is an extension of our previous paper (2) entitled "A modified Markov model for the estimation of computer software performance". The extension is made by assuming that (1) the software system consists of R statistically independent software modules; (2) no failure occurrence while the process is in transition between software modules.

Choe, In-Su ; Gang, Seok-Ho ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 113~129
The purpose of this study is to provide a System Description Algorithm based on the need to describe the system more systematically than the System Dynamics does. The algorithm, which comprises 14 steps, is described in detail and demonstrated through an example of the dynamic market networks.
An Analysis of Hindrance Factors of Process Capability
Song, Seo-Il ; Hwang, Ui-Cheol ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 131~140
This paper analyses the hindrance factors of process capability. The reasons of the products which are out of specification can be accounted on the hindrance factors. An
nquete which consists of 4 categories such as technical knowledge, work performance, work environment, and human relations at home and office, is prepared and handed out to 1000 works to get information. And Spearman's Correlation Coefficient (
) is adapted as an anaysis and consideration criterion. In consequence, it is revealed the next 4 factors become the vital hindrance factors of process capability: (1) unskillful working (2) over load for operators (3) imperfect work environment (4) incoordination of human relations And the correspondent policy can be summarized as follows: (1) propagation & fixation of I.E. techniques (2) harmonization of human relations (3) improvement of work environment (4) strengthening the T.W.I.
Capacity Expansion Models for Optimum Investment Planning
Kim, Seung-Gwon ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 141~154
The capacity expansion problem has been defined. Existing literatures on capacity expansion problems have been reviewed and unified under a structure of problem domain. The problem domain has been defined by three relavent coordinates; function or objective of the project, consideration of resource allocation, and consideration of project sequencing. Long range planning is of vital importance in setting up ultimately efficient capital investment plans to meet immediate demand increase. Simplified expansion sequencing example problems have been introduced and solved to help understanding of a solution scheme.
Greedy Heuristic Algorithm for a Multidepot Aircraft Scheduling and Crew Scheduling Problem
Jang, Byeong-Man ; Park, Sun-Dal ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 155~163
This paper presents a heuristic algorithm for a multidepot aircraft scheduling and crew scheduling with deal-head flights. This algorithm is extended from a Greedy heuristic algorithm for a multi-depot multi-salesman traveling salesman problem. We first transform a given flight schedule into a multi-depot multi-traveling salesman problem, considering aircraft flight policies and crew management constraints. Then we solve this problem by applying a modified Greedy heuristic algorithm.
Long-term International Oil Trade Model for the Analysis of Oil Price and Economic Growth
Kim, Se-Heon ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 165~172
Since energy consumption of developing countries is expected to grow rapidly over the coming decades, the oil-importing developing countries are likely to encounter chronic balance-of-payments difficulties. To analyze the quantitative impacts of this problem, we develop a computable model of international trade. This paper presents four alternative cases - varying the assumptions with respect to energy supplies. This shows that relatively small difference in supplies can lead to 100% differences in the energy prices projected for 1990.
A Computer Simulation Model for Container Terminal Systems
Jo, Deok-Un ;
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 173~187
A computer simulation model for optimum design and determination of optimal operational parameter values for modern container terminal systems was developed through the use of GASP-IV, a subset of SLAM. Input data reflecting current system configuration and operational practices at Pusan container terminal was used to test the model, which resulted in its validation. Possibilities for application of the model in areas of candidate system comparisons, operational parameter testing and forecasting operational performance under future traffic situations, are explained.
Development of Process Capability Table and its Application
Journal of Korean Institute of Industrial Engineers, volume 11, issue 2, 1985, Pages 189~194
Process Capability Index is defined as a ratio between predetermined tolerance and natural tolerance of existent process (
). And it is widely used as a performance measure for quality control activities, and a criterion for process classification. This paper developed a unity-fixed process capability table for convenience to calculate process capability and showed how to use it.
