  • Optimization of production system of polyester manufacturing companies is an important task for strengthening the competitiveness of the domestic polyester industry. The purpose of this study is to present a way to evaluate the goodness of the polyester manufacturing systems determined by the combinations of production facilities and to derive the optimal configuration of the production system. To this end, the criteria or factors for the evaluating polyester production system were derived and the Analytic Hierarchy Process (AHP) was used. Using the AHP model, we derived weights on the criteria for evaluating polyester production system and drew priorities for the configurations of the production systems under consideration.

  • Pedestrians have been exposed to dangerous traffic environments, in which walking spaces in a city decrease without improved facilities even though cars increase. Such poor walking environments are deadly dangerous to the vulnerable as well as the non-vulnerable. This study analyzed the road facilities use characteristics according to a type of vulnerability in order to improve traffic safety and walking environment for vulnerable pedestrians. This study surveyed the vulnerable in terms of issues that they encountered on existing walkways and conducted the analytic hierarchy process (AHP), which took all quantitative and qualitative variables into account. The results of Level-3 analysis were showed that the elderly and the disabled were partially similar; both felt most inconvenient at enter-exit sections, steep walkway and bad paved walkway. Unlike those results, people with children and/or infants answered that overpass or underpass walkways without lifting facilities were most inconvenient walking environments.

  • Purpose: The purpose of this study is to check the importance of higher level, sub higher level and lower alternative factor and the factor for relieved life and also check the comprehensive priority in executed "Safety and relieved life level improvement of apartment house residents by AHP analysis". Method: The safety management evaluation elements and alternatives have been arranged as hierarchical structure based on the preceding studies and the advice of experts for the maintenance and system of apartment house in this study. Study model is used for the survey of pair wise comparison composition targeting experts and AHP analysis method is used for alternative plan ranking, etc. Result: The response result of survey secured the consistency and it is confirmed that safety inspection for apartment house electricity facility is most important for higher level, safety inspection, detailed inspection and diagnosis evaluation are most important for sub higher level and plumbing equipments is most important for alternatives based on the analysis result of relative weight comparison for sub higher level and alternatives for final goal attainment of the study. Conclusion: Plumbing equipments, crime prevention safety and electrical safety are shown as top priority alternatives when observe it with expert manager's point of view for apartment house. It shows that securing the importance of living safety accident and deciding the level of relieved life can be improved are the alternatives of pre-prevention and management strengthening.

  • This paper performed studies on a guide for an environmental assessment necessary to select railroad route optimally, and presented techniques for an environmental friendly route selection using AHP(Analytical Hierarchy Process) as an objective method. The AHP is an approach to decision making that involves multiple choice criteria into a hierarchy and assessing the relative importance of each criterion, and determining an overall ranking of the alternatives. For the purpose of this study, we established the weight and the order of major environmental assessment items based on the survey of experts. The results of the weight by AHP were in order of Fauna & Flora, Topography & Geology, Nature Environmental Assets, Noise & Vibration, Water Quality, Landscape and Air Quality indicating natural environment should be in priority. To develop the more efficient environmental friendly route selection systems, it is necessary to consider economical, technical, and social aspects in addition to environmental consideration.

  • When a ship accident occurs, it is imperative that the captain makes a prompt decision because the accident directly leads to the loss of human lives. The purpose of this study is to quantitatively analyze the main factors and to provide basic data for making decisions in case of ship related contingencies. Experts were surveyed using questionnaires containing eight main factors. The priorities based on relative importance of those factors were determined using the analytic hierarchy process (AHP). As a result, the main priority factors were capsizing (heeling occurs), and fire/explosion, which could have the greatest impact on decision making. We plan to do a larger, more detailed scale survey to improve the reliability of the results. The results above will be used as a basis for the main factors of ships and passenger evacuation decision-making procedures.

  • Intrusion tolerant system enables essential services to maintain for a period of time under system failure, malicious attacks and is gaining more importance in national defense, communication infrastructure, and financial sector. However, few objective evaluation criteria for companies and agencies to introduce an appropriate system are available. This paper proposes a suitability evaluation method, using Analytic hierarchy process and fuzzy integral, for intrusion tolerant system, along with evaluation criteria which considers the characteristics and costs of systems in addition to other factors.

  • Because smart televisions (TVs) have various and innovative functions that are different from traditional TVs, consumers are front with a complex decision-making problem when they want to buy a best TV among alternatives made by many TV makers. TV manufactures have developed and announced different types of smart TV models and they need a comparative study for evaluating their characteristics. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for deciding the best smart TVs regarding many selection criteria. The method provides a decision support for consumers who like to purchase a smart TV. We describe criteria affecting the smart TV selection through a literature review and suggest a user testing method in order to derive accurate judgments from consumers. Using the Expert Choice software package, we show a an numerical example how the priority of smart TVs are computed.

  • This study analyzes the relative importance and priorities on the early childhood teacher's rights using hierarchical analysis process(AHP) and suggests the theoretical and practical implications. We conducted the survey of the practitioners and academics in order to provide comprehensive and balanced discussion on the area of early childhood teacher's rights and sub-factors. The results of analyses show that the professional authority is the most important rights of establishing the early childhood teacher's rights. Second, the results show that the rights to guide young children and to decide on a teaching method are more important than other factors in professional authorities. Third, the results indicate that the right to have an their identity and the right of claim for remuneration are more important than others in the Publicness. In the labor factor, the experts emphasize that the right to make union for early childhood teachers is more important than the right of teachers' union for bargaining. These confirm the difference of the perceptions of the relative importance and priority on the areas of early childhood teacher's rights and sub-factors between the practitioners and academics. Based on these findings, we discuss the implications for improving the early childhood teacher's rights.
