This paper presents a more efficient evaluation of alternatives by use of multi-criteria decision making methodlogy under fuzzy intersectional dependence relations. The performance evaluation of most systems such as weapons, enterprise systems etc. are multiple criteria decision making problems. The descriptions and judgements on these systems are usually linguistic and fuzzy. The traditional methods of Analytic Hierarchy Process(AHP) are mainly used in crisp(non-fuzzy) decision applications with a very unbalanced scale of judgements and rank reversal. To overcome these problems, we will propose a new, general decision making method for evaluation models using fuzzy AHP(FAHP) under fuzzy intersectional dependence relations. The T.M.S alternatives A, B and C will be evaluted by the Fuzzy Analytic Hierachy Process (FAHP) based on entropy weight in this study. We will use symmetric triangular fuzzy numbers to indicate the relative strength of the elements in the hierachy and degree of intersection between criteria. These problems are evaluated by five criteria : tactical criteria, technology criteria, maintenance criteria, economy criteria, advacement criteria.

This study is to obtain the order of the sensitivity of importing marine products with regard to non - economic aspects of considerations under the free - trade. Three criteria are extracted considering various aspects of Korean fishery society. They are the socio - economic, resource - environmental, and policy - appropriateness criterion. The Analytic Hierachy Process(AHP) is used to obtain the estimates of weights among these criteria. First of all, the weights between economic and non - economic in the first hierachy of sensitivity criteria turn out to be 83.3% and 16.7%. Second, the weights among three criteria in the non - economic aspect, the second hierachy, are following that the socio - economic criterion is 19.6%, resource - environmental 31.1%, and policy - appropriateness 49.3% respectively. 47 selected fishes are evaluated based on these three non - economic criteria using 9- point scales. The over - all order of sensitivity is a croaker, hairtail, flatfish, sea breams, and so forth in descending order. The least sensitive fish turns out to be an angler. In addition to the over - all order, the sensitivity based on the three specific non - economic aspects is also investigated. The most sensitive fish in terms of the socio - economic criterion is an hairtail while the least one is a filefish. The most sensitive fish in terms of the resource - environmental criterion is an abalone while the least one is an angler. Finally, the most sensitive fish in terms of the policy - appropriateness is a mackerel while the least one is a small octopus.

This paper describes two contrasting approaches to group decision making involving multiple criteria. A compromise programming method and the analytic hierarchy process are analyzed and compared by using an illustrative example of a computer model selection problem to demonstrate their usefulness as a viable tool for group decision making. This paper further considers some extensions and modifications of there two methods for future study.

For measuring a traffic symbolic confusion quantity and symbolic air pleasantness, we use fuzzy sensor algorithm maded by symbolic information quantity. But for implementation of fuzzy sensor, we use some symbolic information item, this method cannot produce precise output because we use vague fuzzy rule method and we cannot abundance fuzzy for precision of fuzzy rule method. For this reason this paper introduce new fuzzy sensor algorithm composed of not fuzzy rule method but using Analytic Hierachy Process. To prove that new method is good, two type of fuzzy sensor applied to traffic signal controller and through much passing vehicle, two fuzzy sensor compared each other.

Recently, one of countermeasures against aging SOC infrastructures, performance-focused management including the serviceability, functionality, durability, and economics has been changed from the structural safety-focused evaluation has changed into The current inspection and diagnosis for the major SOC facilities in Korea has been carried out by the specific principle of details, and most of them checked by the visual inspection are focused on the repair and rehabilitation of the damaged structures, thus they are the preventive maintenance. However, the performance-focused management should be replaced for the effective and economic maintenance as wells as for the minimization of the damage. In this regard, this study the appropriacy of the current evaluation items about the concrete retaining wall, one of SOC infrastructures as the previous step forward the performance-focused management. In order to deduct the effective evaluation items in order, the entropy, analytic hierachy process (AHP), and promethee analysis were peformed and the results were compared and discussed.

The success or failure of businesses affected by the decision makers, when good decisions go in the direction of social development, the ability to be more successful, while one bad decision away contrary to the trend of social development are less likely to succeed. Today AHP method is widely used to solve critical problems in many areas of life. Analytic Hierarchy Process (AHP) is a quantitative comparison method is used to select a preferred solution using comparable pairs of solutions based on their relative effectiveness against criteria. The purpose of this study is provide an overview of the application of hierarchical analysis methods to solve many different important issues in the field of supply chain management.

As the era of ubiquitous has come, it is able to have more convenient and efficient operation system since many efforts have devoted to developing an appropriate operation system in the ubiquitous environment and applying RFID/USN technology to various parts in the industry. Also, the port logistics area has considered RFID/USN to develop more efficient port logistics environment and improve their efficiency. Therefore, this study investigates current trends of RFID technology and application cases in the port logistics area since RFID stands in the important position of changes of maritime port environment. This study tries to find possible areas for applying RFID technology and analyze expected effects when RFID is adopted those areas. Lastly, the priority level among the possible RFID application fields in the container terminal has been evaluated by experts' survey.

To provide an appropriate knowledge representation technique dependent on a particular domain, we consider the combine analytic hierachy process(CAHP). This is an extended method of the conventional AHP which is useful when two different expert groups are involved. Our problem domain is confined to human resource management including such major activities as planning, selection, placement, compensations, performance evaluation, training, and labor-management relations. We prioritize rules, frames, semantic nets, and predicate logic representation techniques best suited to each and all domains through an exploratory study.
