    MODM(multiobjective decision-making)problem is very complex system for the analysist and decision maker. Therefore, it requires suitable MODM method to solve multiobjective decision-making problem. This paper presents an interactive fuzzy decision making method for solving multiobjective nonlinear programming problems with fuzzy goals and $\alpha$-cut set of fuzzy numbers. In our interactive method, if the decision maker specifies the degree $\alpha$of the objective value and the imprecise goals, λ-mux problem is solved. To examplify the proposed method, an interactive computer programming written in FORTRAN and an illustrate numerical example along with computer outputs are presented.

    This paper constructs Croup Technology process-based learning curve model adjusted to a Group Technology environment which accounts for shared learning that occurs when multiple products utilize some of the same process steps. Through this constructed model, the estimated times and productivity of labor calculated by the Group Technology process-based learning curve model are compared with those generated by employing product-based 1 earning curve model. For sensitivity analysis of the model, the impact of learning rate and the ordered production quantity on the ratio differences between Group Technology process-based learning curve model and product-based learning curve model are examined. These results indicate the critical importance of employing Group Technology process-based learning curve model when a process spans multiple products.

    In the stock marketing. investor needs speedy and accurate decision making for the investment. A stock exchange index provides the important index of the early of 1993 in Korea using Fuzzy Delphi Method(F. D. M) which is widely used to a mid and long range forecasting in decision making problem. In the Fuzzy Delphi method, considerably qualified experts an first requested to give their opinion seperately and without intercommunication. The forecasting data of experts consist of Triangular Fuzzy Number (T.F.N) which represents the pessimistic, moderate, and optimistic forecast of a stock exchange index. A statistical analysis and dissemblance index are then made of these subject data. These new information are then transmitted to the experts once again, and the process of reestimation is continued until the process converges to a reasonable stable forecast of stock exchange index. The goal of this research is to forecast the stock exchange index using F.D.M. in which subjective data of experts are transformed into quasi -objective data index by some statistical analysis and fuzzy operations. (a) A long range forecasting problem must be considered as an uncertain but not random problem. The direct use of fuzzy numbers and fuzzy methods seems to be more compatible and well suited. (b) The experts use their individual competency and subjectivity and this is the very reason why we propose the use of fuzzy concepts. (c) If you ask an expert the following question: Consider the forecasting of the price index of stocks in the near future. This experts wi11 certainly be more comfortable giving an answer to this question using three types of values: the maximum value, the proper value, and the minimum value rather than an answer in terms of the probability.

    Primary prevention of low back injury in industry has focused on assessing the person's ability to perform physical labor. If the job to be performed is known to require lifting and moving of materials which could stress the low back, then special consideration is given to the health and functional capability of the person, s back. The major pursuit in lifting task of research is to provide objective criteria based upon all of the relevant mechanical parameters which describe both man art task so as to minimize the probabilities of injury within the economic constraints of each organization. The purpose of this study is to predict the back compression of persons asked to lift objects while assuming different position by computer simulation. The primary result of this study is that the incidence of low back injury is correlated with higher lifting strenth requirements as determined by assessment of both the location and magnitude of the load lifted. It is, therefore, recommended that load lifting be considered potentially hazardous, and the action limit and the maximum permissiable limit be used to guide corrective action.

    This paper presents a method for analyzing the transfer lines with finite storage buffers. Each machine spends a random amount of time processing each material. This transfer line can be modeled by the tandem queueing system with finite buffers. The great dimensionality of the state space renders the analysis of such system a formidable task. We propose an efficient algorithm to obtain the marginal state probabilities based on the exact algorithm for the two-machine system. Other performance measures, such as the utilization, the blocking probability, the average sojourn time, and the average queue length, can be easily calculated.

    The assumption of reinvestment rate leads to the results conflicting with the priority order of investments determined by net present worth. It has been revealed through various studies that the priority order of projects determined by the criteria based on internal rate of return is different from that determined by present worth. This study is to find out how to define reinvestment rate of return influencing the decision-making of the priority order through examining the meanings of reinvestment rate of capital and true rate of return, and to present some examples with a simple mathematical model.

    This paper is concerned with preventive maintenance model for the items whose failures are dependent on their wear level. The previous maintenance models have used time as their decision variable, but it is not appropriate for the case which have wear dependent processes for their failures. In this paper, we consider an operating item which is under periodic review and which is subject to degradation. The scheduled maintenance (overhaul ) is based on the level of item degradation rather time. A functional equation for the total expected cost over an infinite horizon period is formulated and solved.

    Standard acceptance sampling plans models the production process as a sequence of independent identically distributed Beruoulli random variables. However, the quality of items sampled sequentially from an ongoing production process often exhibits statistical dependency that is not accounted for in standard acceptance sampling plans. In this paper, a dependent production process is modelled as an ARMA process and as a two-state Markov chain. A simulation study of each is performed. A comparison of the probability of acceptance is done for the simulation method and for the approximation method.

    종래에서 부터 원가관리의 대상은 제품시방이 결정되고 제조준비가 대체로 완료된 후의 활동, 즉 제조활동이었다. 그러나 우리나라에서는 제조활동이 자동화, FMS화, CIM화가 진전되어, 제조과정에 들어와서부터 원가를 콘트롤하는 여지가 매우 좁아져 왔다. 따라서 관리효과를 얻기 위해서 제조준비활동이나 제품설계 활동으로 관리대상을 이동시킬 필요가 생기게 되었다. 이와 같은 배경하에서 제품설계단계와 제조준비단계에서 결정되는 신제품의 원가를 관리하고자 하는 것이 여기서 말하는 제품설계단계의 원가관리(일본에서는 원가기획이라고 부르는 경우가 있다. )인것이다. 제품설계단계의 원가관리의 개념은 수년전 부터 확대화의 경향에 있다. 즉, 그것은 단순히 제품설계와 제조준비의 단계에서 결정되는 제품원가의 관리만으로서가 아니라 신제품에서 기대되는 이익의 예측과 관리까지도 포함하기에 이르고 있다. 그리고 제품설계단계의 원가관리의 대상영역에 제품 컨셉트 작성활동이라든가 판매가격설정에 이르는 문제까지 포함하고 있는 것이며, 마케팅 전략이라든가 장기이익계획으로 보아서 전개하는 것으로 보이는 것이다. 이와 같이 아주 다양한 내용을 지닌 제품설계단계의 원가관리로 되고 있는 것이다. 이와 같은 원가기획의 유용성과 발전성을 표시하는 것이며 금후의 연구과제에 대한 명시적인 것이기도 한 것이다. 그러나 여기에서는 이러한 현상을 찾아보면서 제품설계단계의 원가관리에 대한 일반적인 Job plan(제품설계단계의 원가관리를 효과적으로 실시하기 위한 표준적 수준)의 주요과제에 대하여 논술키로 한다.
