Stochastic Combats with Time Limitation
Bae, Do-Seon ; Gwon, Tae-Yeong ;
Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 2~7
The fundamental stochastic duel of Williams and Ancker is combined with the probabilistic linear, square and mixed laws of Brown and Smith when the battle time is limited and interfiring times are continuous. The Probability of a given side's winnig or a draw is derived in a recursive equation with Laplace transforms. Examples with negative exponential firing times are given. In linear law an exact closed form solution is obtained, whereas for square and mixed laws only square (
) duels are considered.
A Study on a Multi-Stage Inventory of Finished Goods
Kim, Jeong-Ja ;
Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 9~14
Inventories of finished products exist in each stage of the channel between production and consumption. An inventory has several functions, which make it possible to produce by economic lot size and to elevate services for consumer by shortening delivery time, etc
. Finished products may be inventoried in delivery-center as well as at the plant where production takes place. So, finshed products must be dealt with as multistage inventory problem, because an inventory functions differently according to its place. The purpose of this study is to determine how much to carry in stock and what stage to carry Though there may be several channels between production and consumption, this study deals with only one main channel, that is, series of ncomponents and determines the optimal inventory policy by introducing the concept of selling probabilities.
Flexibility and Sequential Investment Analysis

Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 15~20
Information on the future availability of invested funds provides a decision maker with additional insight into the characteristics of alternatives in sequential investment analysis. The flexibilty to pursue newly emergent investment opportunities is an important property of decision alternatives that describes the future mobility of invested funds. The primary purpose of this paper is to propose a method for measuring flexibility using the concept of negative project balance with project abandonment option.
A Stochastic Model of Muscle Fatigue in Cyclic Heavy Exertions

Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 21~36
Static muscle contractions when prolonged or frequently repeated result in discomfort, fatigue, and musculosketal injuries. An analytic and quantitative model has been developed in order to expand the working knowledge on muscle fatigue. In this paper, three Markov models of muscle fatigue are developed. These models are based on motor unit fatigue-recovery characteristics obtained from information on motor unit behavior as it relates to fatigue and graded exertions. Three successively more realistic models are developed that involve: (1) homogeneous motor units with intensity-dependent fatigue rates and state-independent recovery rates (the HMSI model); (2) homogeneous motor units, intensity-dependent fatigue rates and state-dependent recovery rates (the HMSD model); and (3) non-homogeneous motor units (i.e., Type S and Type F), intensity-dependent fatigue rates and state-dependent recovery rates (the HMSD model). The result indicate that a simple stochastic model provide a means to analyze the complex nature of muscle fatigue in sequential static exertions.
On the Equivalence of Stackelberg Strategy and Equilibrium Point in a Two-person Nonzero-sum Game
Kim, D.W. ; Bai, D.S. ;
Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 37~43
A sufficient condition for a Stackelberg strategy to coincide with an equilibrium point is presented. Information pattern of a Stackelberg strategy is essentially different from that of an equilibrium solution and therefore the two strategies need not be the same. However, under score restrictions on the cost functions the difference in information patterns between the two strategies can be disregarded so that the two strategies coincide. The result is extended to the case of discrete-time dynamic games.
Development of Logistics Support Systems in a Large Machinery Company
Lee, Gi-Seok ;
Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 45~56
This report presents the development of an integrated logistics support system for a large-scale machinery manufacturing organization. The system consists of 3 major production management systems and 5 assisting systems. The major systems are: i) production planning and control system, ii) cost control system, and iii) material management system. The assisting systems are: i) personnel management system. ii) technology transfer system, iii) quality assurance system, iv) marketing assisting system, and v) management information system. In addition, other management systems such as planning system, R.&.D. system can be considered according to the organizational need. Several system flow models are developed and presented for the total logistics support system.
Performance and Productivity of Researchers in the Area of Science and Technology : A Review
Jang, Gyeong ; Lee, Jin-Ju ;
Journal of Korean Institute of Industrial Engineers, volume 5, issue 2, 1979, Pages 57~69
This review focuses on the individual performance and productivity of researchers in the area of science and technology. The researchers in the paper are classified into individual inventors without organizational affiliation and researchers in the organization, which are distinguished by cosmopolitanic professionals and local institutionalists. The productivity of researchers is in general measured by different indicators or measurement scales such as: i) subjective evaluation of overall research performance, (ii) the number of published papers, reports and books, iii) the quality of research output (e.g. citation frequency), iv) originality of research ouput (e,g, patents), v) multiple measurement scales, etc. According to the literature based on empirical study, the productivity of individual reseachers is positively related to the degree of freedom, communication, diversity, dedication, and motivation and negatively related to the degree of similarity, and satisfaction. However, other factors such as creativity, age, supervisory behavior and group characteristics have shown irregular direction of correlation.
