자동화 제조 시스템에 시뮬레이션 기법을 사용하기 인해서는 자재취급 시스템의 성과를 동적으로 측정해야만 한다. 다중 에이전트 기술은 제조시스템을 지능화 시키고, 분산처리 된 시뮬레이터 개발에 적합하다. 다중 에이전트 시스템은 하나의 조정 에이전트와 다수의 응용 에이전트들로 구성된다. AGVS 시뮬레이터에 있어 이슈는 운반차량의 대수 결정, 양단방향 흐름에서의 이동경로 결정등과 같은 set-up문제와 운영문제로 구분 지을 수 있다. 본 논문에서는 다중 에이전트 기술을 사용하고, 실시간 교착상태 해법 알고리즘이 포함된 시뮬레이터를 소개한다. 시뮬레이터는 잘 알려진 프로이드(Floyd) 알고리즘을 사용하여 AGVS의 최단 이동경로를 구성된다. 움직이고 있는 차량 에이전트는 조정 에이전트에 의해 실시간 제어로 작동되고, AGV는 경로확인 알고리즘을 사용하여 충돌과 교착상태를 피한다. AGV의 위치는 수평시간 계획법에 근거하여 동적으로 재계산된다. 충돌해소 알고리즘은 어떠한 배치 형태에서라도, 그리고 큰 규모의 문제에서도 AGVS의 운영 중의 주행문제 해결을 보장한다. 시뮬레이터는 AGV들의 AGVS 칸트차트를 통하여 작동정보를 받고, 표현한다. 제안된 알고리즘의 성과와 다중 에이전트 기술을 사용하여 개발한 시뮬레이터는 실험을 통하여 검증된다.

A facility layout design (FLD) problem can be generally introduced as assignment of facilities (departments) to a site such that a set of criteria are satisfied or some objectives are minimized (maximized). Hence, it can be considered as a multi-criteria problem due to the presence of qualitative criteria such as maintenance or flexibility and quantitative criteria such as the total cost of handling material. The VIKOR method was developed to solve multiple criteria decision making problems with conflicting and non-commensurable (different units) criteria, assuming that compromising is acceptable for conflict resolution, the decision maker wants a solution that is the closest to the ideal, and the alternatives are evaluated according to all established criteria. This paper proposes a hierarchical analytic hierarchy process (AHP) and VIKOR approach to solve the FLD problem. A computer-aided layout-planning tool is adopted to generate the facility layout problems, as well as their quantitative data. The qualitative performance measures are weighted by AHP. VIKOR is then used to solve the FLD problem. Finally, the proposed integrated procedure is applied to three real-time examples.

The purpose of this work is to analyze the factors, criteria and importance that shippers in the international logistics industry take into account in choosing third-party logistics, and thereby to propose the directions of the areas and functions that third-party logistics will need to enhance on the basis of Analytic Hierarchy Process (AHP) methodology. To do that, this work collected and analyzed materials about changing environments of logistic industry and previous studies, and especially conducted a questionnaire survey on the factors to choose third-party logistics with the study subjects of shippers in the international logistics industry. To draw attribute factors, this work repeatedly chose and classified candidate factors through Delphi technique on the basis of the data of previous studies. The analysis results are presented as follows: regarding pairwise comparison between logistic cost and logistic service in relation of conflict, logistic service was recognized to be more important than logistic cost; regarding pairwise comparison between corporate capability and logistic cost, logistic cost was recognized to be more important; and regarding comprehensive evaluation, logistic service factors, including accuracy of order handling, service reliability, freight damage and compensation, a degree of fulfillment of promise, quality of transportation, and problem-solving ability, were found to be in high position.

Purpose: The purpose of the study was to understand low-income elders' experiences of community-based u-Health services. Methods: Qualitative data were collected from 11 participants. All interviews were recorded and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. Results: Three themes and eight sub-themes emerged as a result of analysis. The three main themes were 'recovered confidence and health condition,' 'trial and error in change,' and 'hope.'The eight sub-themes were 'the burden and efforts to overcome it in using bio-signal device,' 'ambivalence due to changing lifestyle,' 'increase of care time, decrease of pressure', 'conflict under environmental constraints,' 'difficulty in prioritizing health management,' 'discouragement in handling new devices,' 'desire not to be a burden to their children-gradual fulfillment of learning needs,' and 'long for broadening coverage range of services.' Conclusion: The findings of this study demonstrate that low-income elders among the participants have different needs in using u-Health services. Therefore, health professionals need to give personalized education to deal with their conflicts and requirements, especially emotional and environmental support in order for them to successfully accept the u-Health services for self-care.

Shape optimization of the 3-dimensional WIG airfoil with 3.0-aspect ratio has been performed by using the multi-objective genetic algorithm. The WIG ship effectively floating above the surface by the ram effect and the virtual additional aspect ratio by a ground is one of next-generation and cost-effective transportations. Unlike the airplane flying out of the ground effect, a WIG ship has possibility to capsize because of unsatisfying the static stability. The WIG ship should satisfy aerodynamic properties as well as a static stability. They tend to strong contradict and it is difficult to satisfy aerodynamic properties and static stability simultaneously. It is inevitable that lift force has to scarify to obtain a static stability. Multi-objective optimization technique that the individual objectives are considered separately instead of weighting can overcome the conflict. Due to handling individual objectives, the optimum cannot be unique but a set of nondominated potential solutions: pareto optimum. There are three objectives; lift coefficient, lift-to-drag ratio and static stability. After a few evolutions, the non-dominated pareto individuals can be obtained. Pareto sets are all the set of possible and excellent solution across the design space. At any selections of the pareto set, these are no better solutions in all design space

ADR has recently been expanded, making it possible to solve traffic accident disputes, which is a matter of urgency for parties to avoid. This point serves as an important procedural element. Such disputes are an area that requires a quick resolution. To try to solve any dispute that occurs in the complex environment of modern times one-by-one through litigation does not make sense. It gives an undue burden on the judicial body and the investigation agency. Like litigation, today's arbitration system, should have effective conflict resolution. The arbitration of automobile traffic accident disputes can be seen as roughly adjusted through the insurance company, the Dispute Coordinating Committee, and the Crime Victims Protection Act. It consists of experts mainly, and the resolution of automobile traffic accident disputes can be resolved through the Sajonsa and workers insurance company. However, adjustments to failure incident mostly need attention. Most of a company's compensation insurance indemnity needs to be processed in practice. In addition, a vicious cycle of litigation and delay period is repeated if a lawyer is appointed. There are unreasonable adjustment systems in the midst of these. Avoiding traffic accidents allows parties to resolve disputes better. Arbitration of disputes in automobile traffic accidents handled by arbitration institutions is desirable. It is determined that the handling of a case by a village attorney is efficient.

In the present work, a main purpose is to propose a fuzzy integral-based aggregation framework to complementarily combine partial information due to lack of completeness. Based on Choquet integral (CI) viewed as monotone expectation, we take into account complementary, non-interactive, and substitutive aggregations of different sources of defective information. A CI-based system representing upper, conventional, and lower expectations is designed far handling three aggregation attitudes towards uncertain information. In particular, based on Choquet integrals for belief measure, probability measure, and plausibility measure, CI$\_$bi/-, CI$\_$pr/ and CI$\_$pl/-aggregator are constructed, respectively. To illustrate a validity of proposed aggregation framework, multiple matching systems are developed by combining three simple individual template-matching systems and tested under various image variations. Finally, compared to individual matchers as well as other traditional multiple matchers in terms of an accuracy rate, it is shown that a proposed CI-aggregator system, {CI$\_$bl/-aggregator, CI$\_$pl/-aggregator, Cl$\_$pl/-aggregator}, is likely to offer a potential framework for either enhancing completeness or for resolving conflict or for reducing uncertainty of partial information.

In 1978, Chinese reform and opening caused a big changes in Chinese labor relationship. Through reforming and opening, China gave up part of state ownership system and group ownership system, permitted private ownership system, and also opened the way for capitalists to ride again. Since China was established, the labor relationship ceased for 30 years has been appeared. However because the top priority aim of China's reform was economic growth, the protection of the rights and interests of labor was pushed back on the policy priority list. China takes foreign capitals based on cheap labor force quickly and China come up the worldwide plants. Since reformed, China keeps an economic growth rate of 9.7% annually for 30years. This economic growth is based on labor's sacrifice. However, Chinese fast economic growth causes side effects such as increasement of the gap between the wealthy and the poor, increasement of unbalanced development between regions, and the increasement of conflict between labor and management. Especially, according to changes in labors' level of consciousness, the labors recognized that their rights and interests are exploited by employers. Therefore, the labor dispute is continuously increasing. Chinese government changes their policy from the policy focusing on enterprise development to the policy protecting labor's rights and interests. In order to protect labor's rights and interests, China conducts labor contract law and labor dispute conciliation arbitration law in 2008. This kind of changes in Chinese labor environment affect a lot to Korean companies which already entered into China or are willing to enter. According to studying on present situation and resolution system in Chinese labor dispute, this paper suggests the proper countermeasure related to labor dispute of Korean companies which entered in China. First, the success rate of labor dispute conciliation by enterprise labor dispute conciliation committee is around 20% during recent several years and the success rate by year is in decline. Therefore, when labor dispute is occurred, our companies which entered into China better use other labor dispute methods such as negotiation and arbitration than conciliation in order to settle a conflict. Second, from the Korean enterprises entered in China point of view, there exists a problem not to sue except special cases which provided in the law even though they are dissatisfied with arbitrate judgment. Thus, when labor dispute occurred, Korean enterprises try to do best to settle the dispute through negotiation. However, in case of that the dispute cannot be settled by negotiation, they have to attend in the arbitration as if it is a last chance. Third, Korean enterprises keep in mind that dispute handling procedures between labor union and users or between labor group and users are different, and then deal with separately. Thus, dispute between labor and users have to follow arbitrate procedures as a necessary procedure, but in case of dispute related to group contract, namely dispute against labor union, labor dispute can be settled by arbitrate or suit, so after figuring out the situation exactly, it is necessary to select more advantageous way in order to settle the dispute. Moreover, in case of the dispute between labor union, they have to keep in mind that conciliation procedures cannot be used.
