In order to successfully develop a large complex system, it is important that the systems engineering processes take into account the program context and characteristics. Among these processes, the requirements management process requires a management plan based on the program plans and systems engineering management plan (SEMP) to the connection with the program management system and the policy directives. In this paper, a systems engineering based requirement management scheme and guidelines for writing requirements are proposed. is proposed.

This study was to identify the effect of the satisfaction of certification, the educational use of the company offering certificate, the system of confirmation of the same model and the demographic aspect on the companies to see if compulsory certification(KC certificate) has negative effects on company management. First, the satisfaction of certification could reflect positive influences on company management. Second, there is no statistical significance in the education from the company offering certificate as a result of analyzing relationships but education is required and has an effect on improving quality according to the result of frequency analysis. Last, the system to declare by identifying the same model has a difference in significance in sales account, the development of products and warranty service for products.

In the manufacturing process of ready-mixed concrete, quantity management directly affects the workability and strength of concrete. Therefore, water quantity is the most important management factor for water quality control of ready-mixed concrete. It can be said that the number of unit water in the mix design, the water quantity due to the surface water contained in the aggregate used, and the water quantity taking into account the concentration of sludge contained in the recycling water when using the recycling water are factors that affect the quantity management of ready-mixed concrete. In this study, as a stable quality control method of ready-mixed concrete, a quantity management method by aggregate surface water and a sludge concentration management method according to the use of recycling water were proposed. Thus, we tried to suggest an efficient quantity management method for stabilizing the quality of ready-mixed concrete.

Blindness or visually handicaps are found to be an important factor destroying lifestyles as well as a physical problem. According to the data of handicapped person's(v.h.p) registered in Korea, the number of v.h.p. has not decreased. Especially, visual handicapped adolescents (v.h.a.) suffer from an insufficiency of social support under the current education system. There is a special education system for v.h.a. in Korea, and, as a result v.h.a.'s are educated separately from general students and communites. Compared with the self-conception of general students, v.h.a.'s have a more negative self-conception. Among former studies 51.7% of v.h.p's are not in good health. This, of course, means that their handicap impacts on other health problems. The first purpose of this study is to find out the causes of disease and the degree of social support, self-esteem, health management behavior provided and then to analyze the effect of self-esteem and social support on their behavior. To accomplish these purposes, visually handicapped the middle and high school students in Seoul city and Kyung-gi province were selected and 300 students sampled. The main results are as follows : 1) The highest specific handicap is impaired lenses (19.7%). 2. There were high correlations between health management behavior, self-esteem, and social support. 3. Social support is a more important variable than self-esteem on health management behavior. 4. Age of entry and length of stay in their special dormitories, and teacher's support account for 16% of psychological health management behavior 5. Age of entry in their special dormitory and total degree of social support account for 12% of preventive health behavior.

Using the p chart is not adequate in case that there are lots of data and it is difficult to divide into products conforming or nonconforming because of obscurity of binary classification. So we need to design a new control chart which represents obscure situation efficiently. This study deals with the method to performing arithmetic operation representing fuzzy data into fuzzy set by applying fuzzy set theory and designs a new control chart taking account of a concept of classification on the term set and membership function associated with term set.

The BMAP/M/N/O queueing system operating in Markovian random environment is investigated. The stationary distribution of the system is calculated. Loss probability and other performance measures are calculated. Numerical experiments which show the necessity of taking into account the influence of random environment and correlation in input flow are presented.

In today's business transactions, it is more and more common to see that the buyers are allowed some grace period before they settle the account with the supplier. In this regard, we analyze the problem of determining the buyer's EOQ when the supplier allows day-terms credit. For the analysis, it is assumed that the buyer's demand rate is a function of the on -hand inventory level and the relevant mathematical model is developed.

Firms pursue new business opportunities for growth. Market development strategy is one of the growth strategies, which develops new market segments with current products. However, new market generally has high uncertainty, or high risk. Firms should consider the risk in making and implementing the market development strategy. In this paper, an optimal marketing resource allocation model is developed, taking into account the risk attitude of a firm in market development. Under the assumption of exponential utility function, the global optimal solution is derived, and the implications are provided.

In order to recommend future national policy directions on energy supply and consumption and to suggest energy technological priorities to be developed, comprehensive energy models have been developed through this study in a sense of strategic and systematic approach. The “energy input-output model” has been formulated to analyze the mutual impacts between energy consumption patterns and industrial structures and to calculate energy intensities of industrial sectors. The long-term energy demands to the year 2000 were forecasted by using multi-regressional method and the optimal energy flow balances for five-year interval have been studied by using the “energy linear programming model” being took full account of interfuel substitutability and technology.
