A wrong machine, in the manufacturing company, is in want of repair from the repairman. In this case, many queueing-phenomenon is produced. The ultimate goal of the decision problems by the queueing analysis is to achive and economic balance between the cost of service and the cost associated with waiting for that service. The purpose of this study is as follow: 1) The random occurrence of mecanical trouble, in process, is analysised by the probability model. 2) The policy decision is to obtain the minimize cost of the queueing process. (1) The increase of the service level. (2) The decrease of the traffic intensity. As an analysis-method, the system analysis requires to induce M/M/I type model on a several supposition and draw up M/M/S type model.

The purpose of this study is to provide some basic data which can be helpful for improving the methods of mathematics teaching-learning emphasizing the affective factors by investigating the effect on affective characteristics and mathematical problem solving ability of the students on the elementary school sixth grade. In order to achieve these purpose, the following research problems were set up for the present study: The results of this study are as follows: First, it was appeared that there was not any difference on attitude on mathematics, belief, self-confidence and the degree of mathematical problem solving ability by sex. Second, it was appeared that there was some statistical meaningful difference on attitude on mathematics, belief, self-confidence and the degree of mathematical problem solving ability according to high middle low ability on mathematics which the students think that they have. Based on the results of this study, I'd like to give some suggestions as followings to provide some help to teaching and learning mathematics. First, the succeeding studies are needed by selecting different population from the population of this study, classifying low-ranking factors consisting of affective characteristics differently from this study, compounding each low-ranking factors in various manners like using new items, etc. Second, the succeeding studies are needed in this part, because what mathematical belief teachers have mathematics can have an effect on students' mathematical belief and action as well as on teachers' thinking process and action in the class. Third, the succeeding studies are needed to develop concrete field study and program which can be helpful for improving actually students' affective behavior characteristics in school field.

Any groups or organizations need a certain ideology to accomplish their goals and objectives effectively in integrating its members in the same pattern of normative values and beliefs. While the business enterprise is a type of social organization, it need also a particular ideology, as it is called managerial ideology. This managerial ideology play an important role in motivating and integrating its member to achieve its own objective. The objective of this study is to identify and analyze the characteristics of the managerial ideologies in Gyeongsang Nam-Do, Korea and to suggest the orientation in search of new managerial ideologies conformable to the dynamic change of business environment. As the mannagerial ideologies are expressed in the form of enterprise percepts in Korea, we have gathered the enterprise percepts in this region by the questionnaire and the telephone inquiry method and analyzed them by the content dynamically method. We made this survey on 132 enterprises. By the way, 44 enterprises in telephone inquiry had no enterprise percepts. The findings through the content analysis and investigation of the enterprise percepts in this region are as follows : (1) 30% or more of 88 enterprises use such vocabularies as 'Songsil'(sincerity), 'inhwa' (harmonious personal relations), 'gunmyeon'(diligence), and 'dangyeol'(unity) in enterprise percepts ; (2) As the greater part of enterprises (70/88) use Chinese words and phrases in expressing their managerial ideologies in the enterprise percepts, the enterprise percepts included abstract concepts; (3) Although it is necessary to find new managerial ideology suitable to the change of business environment, the managerial ideologies of the greater part of the enterprises in this region take the former state and remain unchanged. From these findings, it may be possible to suggest as follows : (1) Modern managers have to grope new managerial ideologies appropriate to the change of business environment in outgrowing its former state. (2) Not as simple slogan expressed as a matter of form, managers must use their endeavors for the better recongnition of managerial ideologies to emplogyees by the novel and easy expression. (3) Even the small enterprises have to enact also their own enterprise percepts to promote the attachment to their enterprises and the group conhesiveness and then to set down as the frame of performance improvement.

The standard accounting system, in the management of a company, ought to be constituted a information source to offer the useful information and are utilized as a menas of rational making-decision. The basic function of standard accounting system are as follows. First, it is possible to totalize the manufacturing cost to accor on a account of the manufacture. Second, we are able to grasp the manufacturing results. Third, we can estimate to difference between the standard accounting and manufacturing results. It is the purpose of this paper to suggest method of standard accounting system that we are able to give the more detailed information in making-decision, and it is possible to separate the data as totalization, classification, and control in the work standardization.

本論文은 自動車關聯産業에서의 서브어셈블리에 대한 單位當總投入材料費와 總純材料費와의 關係를 評價하는 問題를 다룬다. 投入材料費와 純材料費사이에 퍼지니스가 存在한다고 看做하여, 可能性모델을 根據로 하는 퍼지線形回歸分析을 利用하여 各서브에셈블리의 係數를 퍼지數로 求하는 材料費評價問題를 解決하고자 하는 새로운 手法이다. This paper purposes to estimate the relation between total input material cost and total net material cost of sub-assembly in an automotive industry. We suggest a new method to estimate the parameters of each sub-assembly which has fuzzy numbers. We used the fuzzy linear regression analysis based on possibility model in the material cost problem.

In case of quality inspection of products by the sensory inspection, it is difficult to avoid two types of errors. Good products can be regarded as bad products or bad products can be regarded as good products due to the fuzziness of inspectors. The inspectors can be affected by the environment, and physical or psychological characteristics. The opportunity costs are different according to two types of errors. In this paper, an evaluation of sensory test data is proposed including cost caused by incorrect decision.

Loading, in production planing step, is a prearranged plan which has a quantitative characteristic. In this case, loading is controlled by the final production's man-hour and present man or machine ability. We suggest that the man-hour saving scheme consists of heuristic method. 1) Extract control possibility factors from theoretical model of the loading estimate. 2) These factors are made out several alternative suggestion by the heuristic simulation. 3) Estimate the capacity man-hour based on each alternative suggestion. 4) Make out the alternative suggestion that has the maximum economical valuation in comparison with limit man-hour or saving man-hour. This is the optimum man-hour.

本 論文은 重工業系列에 從事하는 作業者들의 스트레스와 스트레스 要素에 대하여 硏究했다. 對象으로 한세 會社의 스트레스를 評價하고, 生産職社員과 事務職社員 間의 스트레스를 調査하기 위하여 SACL을 適用했다. 本 硏究는 各 部署別로 랜덤하게 無記名 앙케이트 方式으로 490名으로부터 應答을 받아 資料를 處理했다. 여기서, 스트레스는 勞動組合의 有無와 關係가 있을 뿐만 아니라, 年齡, 休日勤務, 性別과 勤務形態와도 깊은 關係가 있음을 알 수 있고, 더우기 勞動組合이 없는 會社에서 勤務하는 社員들이 보다 많은 不平을 함을 알 수 있다. This paper presents the stress moods of workers experienced in heavy industries, and to examine their effects on overall job stressors. To evaluate the effects of stress moods among three companies, we applied the SACL to the investigation of the stress moods between blue-collar workers and white-collar workers. This paper was conducted with 490 subjects and anonymous questionnaire was distributed to each division. Through out analysis, we could find that the score of surveyed stress mood is related with not only the presence of labor union but also "Age", "Holiday work", "Sex", and "Type of duty". Moreover, the workers working for a company without a labor union complained more often than the workers with a labor union, regardless of the difference between white-collar and blue-collar workers.
