R & D 課題選定의 決定模型에 관한 考察 : with emphasis on the Scoring Model 評點法 模型의 特性을 中心으로
高載乾 제주대학교 1988 논문집 Vol.26 No.1
Methods for evaluating individual projects range from single checklists to complex decisions trees which indentify interrelationship and account for risk. Selecting an appropriate R&D decision methodoloy to support program management is to some degree a dynamic process since the research environment is subject to continual change with time. The futrure situation of the organization thus depends in part on the research and development activities which are proposed and embarked up, and the selection of such R&D projects is, in turn, dependent on the amount of effort and resources which the organization devotes to these R&D activites in thE R&D activites in the form of financial investment and manpower. A literature search showed that many studies hafe been made of the R&D project evaluation and selection problem and various formal project selection method have been proposed. These method have been classified into three type according to the basic approach used, these being called the "decision theory" approach, the "economic analysis" approach and the "Operations Research" approach. The decision theory approach suggests certain factors in terms of which aproject proposal might be evalluated, and derives a scoring model whereby a rating on an empirical scale is made for each factor considered, and these rating are combined either by multiplication or as a weighted sum or accordign to heuristic rules to derive a numerical score for each project proposal. The projects then selected are those with the hightest scores, the number of projects selected being determined by constraint of the total available budget. The scoring model uses project scores as a basis for project selection and in a linear model. Since project are evaluated on the basis of linear funtion and are ranked using an ordinal scale, there is no way to measure directly how much one project is better then another. The scoring model does not enable management to evaluate the profitability or risk of project in the usual business terms. Due to the absence of a formal and operational structure, the scoring model is often thought of as being considerably less accurate in its ability to process project data than ROI or mathematical programming approach to project evaluation. However, the scoring model does provide a simple and useful cheeklist of all relevant factor, including some intangible factors. The model uses a consensus of the judgement and experience of knowledgeable personnel, along with information that is gererally avaibable scoring model can be adapted to changed in competition and technology by the modification of facfors and scale.

資材所要計劃에 관한 硏究 : MRP시스템의 理論을 中心으로
高載乾 제주대학교 1983 논문집 Vol.15 No.2
Material requirements Planning (MRP) is a computerized data information system that can support scheduling and inventory inanufacturing functions, The MRP system is a logical means of taking an assembled end item (product) and exploding the item into its components parts. The component parts (materials) are then aggregated according to their due date. The subsystems of MRP include a master schedule, an inventory status file, and a bill of material file for product structure. The outputs from the MRP systems are order release requirements, order rescheduling, and planned order. Key features of MRP systems are (1) the time phasing of requirements, (2) planned order release, (3) generation of lower-level requirements, (4) the rescheduling capability provided. As eack week passes, planned orders are released and any changes in requirements and due dates are entered into the computer data base as they occur. The disadvantages of MRP lie primarily in the assumptions that must be met before MRP can be utilized. A computer is necessary ; the product structure must be assembley oriented ; bill of materials and inventory status he assembled and computerized ; and a valid master schedule must exist, The last assumption, a required master schedule is critically dependent upon good forecasts or firm orders concerning future demand. Another disadvantage has to be with data integrity. Unreliable inventory data from the shop floor can wreck a well planned MRP system. Training personnel to accurate records is not an easy task, but it is critical to successful MRP implementation. The principal prerequsites; and assumptions implied by standard MRP system are as follows; (1) A master production Schedule exists and can be stated in bill Of material terms. (2) All inventory items are uniquely identified. (3) A bill of material exists at planning time. (4) Inventory records containing data on the status of every item are available. (5) Individual item lead times are known. (5) Every inventory item goes into and out of stock.

고재건,김형길 제주대학교 환경연구소 1997 환경연구논문집 : 제주대 Vol.5 No.-
The social responsibility of Corporate requires that organizations consider seriously the impact of their actions on society. By the ecological environment trends, managers need to be aware of the threats and opportunities associated with important trends in the natural environment: shortage of raw materials, increased cost of energy, increased levels of pollution, changing role of government in environment protection and the heightening of consumers' sense of environment. According to the result of this survey on EMS(i.e., Environmental Management System) the level of small business in Cheju was low. In order to increase the competitive power of Cheju small business the following things are needed: environment education program for managers and employees, supporting system for introducing ISO 14000, acquirements of Environmental Labelling and strengthening of technology and administrative & financial support.

The aims of this study is to grasp how the level of (human) service quality is and what method should be taken to improve the quality of service in tourist hotels on Cheju. This paper studied how the nature of sevice and its characterristics are mainly using William B. Martin'c CSAS that presents critical factors of hotel service quality. And in order to find out the level of service in tourist hotels on Cheju and their types, we've attempted actual analysis using valuation by other people. And the result is following: First, there were pretty much difference of service quality to clients among different classes of hotels. But as higher class hotel is not always estimated as it serve high quality service, we can say the estimating quality of service has relative attribution. Second, according to the result from the relations between service-man's back-ground and quality of service, the factors of age are related with all factors of change of service quality but the factors of sex, frequency of hotel use and occupation are not related with the quality of service. Third, the result of correlation analysis between the factors of change of service quality, showed that there is a closed relationship between the quality of formal service and personal service. Fourth, the service type of hotel employees was the type that clients are satisfied, which the levels of quality of formal service and personal service are both high. On the base of this result, we may represent some ways to improve the quality of service in tourist hotels on Cheju. First, hotels have to manage their personal and invest on it. Second, hotels have to establish a management system of service quality and develop it continuously. Third, to improve formal service quality, they have to prepare the SOP(standard operating procedure) and let workers serve by it. Meanwhile, the limits of this study is as folow:First, there are not enough documents and studies related to measuring and managing service quality. Second, the problem may occur because we analyze statistics of the data after changing the quality of service to the numerical value. And thdere may also make a mistake as the research by question which is answered under clients' actual experience and perference. Third, planning of research, collection and analysis were not so elaborate. This study attempts to search the quality management of service. In future study, there has to be more elaborate meausre of sevice quality and general characteristics of service type and more objective measuring methods should be developed.
