A Study on the Actual Condition of Curriculum Composition by Factor Analysis
Lee, Sun-Yo ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 49~58
The purpose of this study was to analyze the actual condition of curriculum composition by factor analysis, then to find out the peculiarity of each factor through factor loading. The method adopted here is to classify and arrange the curricula in accordance with the similarity of each subject, to put it into computer, and to get 16 factors whose eigenvalues are at least 1.00. Consequentely, before the orthogonal rotation 67% of the curricula which have the given factors and maximum factor loading were distributed from factor 1 to factor 4, and after orthogonal rotation 45% of the curricula were distribued.
A Work Scheduling Based on Analysis of Performance Data
Kim, Dong-Chan ; Kim, U-Sik ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 59~66
This paper is a work scheduling for design of piping Department of chemical plant using accumulated curve. Accumulated curve prepared by analysis of performance data, collected executed manhours for chemical plant of "D" Company during the past two years. It compared scheduled manhours with actual used manhours up to six months, put into the form of figures and charts the results can he summarized as below; 1) It can he found an important factor of critical control thus piping department got 30% of total scheduled menhours. 2) A plan of manpower mobilization can be scheduled before work starting. 3) Project progress can he found easily as put into the form of figures and charts for schedule to actual.
Some Problems of the Transfer of Technology from the Developed Countries to the LDCs
Hahm, Hyo-Joon ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 67~75
This paper attempts to identify the factors which are directly related to the effective transfer of technology from developed countries to LDCs. The recipient countries should have the capability of alteration/adaptation based on cost-minimization criteria. Some problems are such that technologies are transferred on the conditions of MNFs, packaged forms and under state management which result in lack of competitive pressure. Non-technological criteria are shown to be a problem under state management in the transaction of technology.
An Application of Dynamic Programming to the Selection of Optimal Production Lengths Based on the Minimum Cutting Loss
Jo, Gyu-Gap ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 77~81
The assortment problem with deterministic demand has been formulated so that a dynamic programming can be applied to find optimal production lengths that will minimize the sum of cutting losses. The original minimization problem can be reformulated as the maximization problem with a different objective function. This problem can be solved by the dynamic programming technique. A numerical example illustrates this approach. The ratio of computation amount of emumeration method to that of this dynamic programming is approximately n to 1.
Reliability and Effectiveness of Electric Power Generating Systems
Kim, Yeong-Hwi ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 83~90
Frequency and duration method is a well known model in the generation reserve reguirement planning area. In this paper, the model is used to measure the effect of increased failure rates of individual generating units on the capability of power system.
An Industrial Sector Model Formulation and its Computation for Policy Analysis
An, Byeong-Hun ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 91~96
A modeling framework and its computational methodology for an industrial sector of the economy are investigated. The suggested industrial sector model is characterized by a programming (process analysis) representation of a production sector and an econometric estimation of the price sensitive (own and cross-prices) demands. By introducing the price sensitive demands into the process analysis representation of the production sector, it becomes possible to analyze and plan the pricing policy, the optimal production schedules and capacity expansion plans within a single framework. The computational scheme suggested in the report is based on the iterative approach each of which solves a separable convex programming problem.
A Mathematical Model of a Central District Heating System for an Urban Residential Community
Yoo, Beyong-Woo ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 97~105
A mathematical model is developed in order to describe the network configuration and heating distribution to a Central District Heating System for an Urban Residential Community. The purpose of using this model is to optimize operating costs and to distribute heat to the Residential Community efficiently. In particular, because of the inherent nonlinearity and dual optimization of the problem a dyamic programming approach is taken. It is turned out that the optimal cost of the system is a strong non-linear function of the network. In particular, it is found that increasing N, the number of houses, may not necessarily imply increased costs. It is felt that past failure of producing economical systems may be due to the improper attention given to the network.
Optimal Control of Dualistic Economic Growth
Park, Sung-Joo ;
Journal of Korean Institute of Industrial Engineers, volume 4, issue 2, 1978, Pages 107~118
The paper illustrates a possible application of control theory to an economic growth system. Simultaneous nonlinear system of differential equations has been modeled which is different from the traditional formulation, based on the theory of economic growth for a two-sector (dual) economy. Necessary and sufficient conditions for the existence of the optimal control are derived directly from the Hamiltonian, and the optimal controls are also obtained by solving simultaneous equations. Obtaining the trajectories of the optimal control and state variables, however, should rely on the numerical procedures. Empirical application has been conducted for the case of the Korean economy as an illustration.
