  • This paper discusses a fitness of the control on intersection using fuzzy analytic hierachy process. The validity of control of traffic signal on intersection is the fitness of phase and cycle on the intersection. The validity of the controller is cleared by the comparison of the delay time of vehicle. Fuzzy analytic hierachy process clears the grade of validity of the fixed cycle time controller and adaptive fixed cycle time and fuzzy trafic controller and proposes a new control type a traffic signal by this fuzzy analytic hierachy process.

  • This paper discusses a fitness of the control on intersection network using fuzzy analytic hierachy process. The validity of control of traffic signal on intersection is phase, cycle of intersection. But the aigent of traffic intersection network is relative of intersection article. Therefor the aigent of traffic network intersection is before intersection passing vechile number, delayed vechile number. Fuzzy analytic hierachy process clears the grade of validity of the fixed cycle time controller and adaptive fixed cycle time and fuzzy traffic controller and proposes a new control type a traffic signal by this fuzzy analytic hierachy process.

  • The paper presents a method for decision the optimal cycle time during the vehicle traffic control in single intersection with AHP. To solve this uncertainty optimization problem, the optimization index in the form of linear addition and fuzzy measurement is assumed and fuzzy integral is used. Examples of solution for two cases of optimal cycle time in two traffic controller are presented and compared.

  • Traffic monitoring method is mainly loop detector and piezo sensor. But this method is only detecting the number of vehicle. Monitoring traffic volume is not checking the number of vehicle but checking the length of access road, width of road, number of passing people, passing vehicle, delayed vehicle. The traffic signal control cycle is not fixed by only passing vehicle number but all related traffic proposal. This paper proposed selecting common characteristic out of each unrelated traffic proposal through Analytic Hierachy Process and this characteristic is applied to compose fuzzy sensor algorithm which find out new traffic volume concept of confusion degree. The accumulated delayed vehicle time is shorter in new fuzzy sensor algorithm applied by AHP than other traffic method

  • Fixed cycle traffic signal controller is pattern type controller. This method is that one concluding traffic proposal affect fixed cycle controller to deciding cycle time during 24 hours. Traffic intersection jam is caused traffic controller supervisor input wrong traffic proposal. The available to traffic controller is traffic proposal is not selected by an outward look but propriety traffic proposal is compared with each other. This paper presents that property traffic proposal adopted to fixed cycle controller by fuzzy analytic hierachy process and new proposal adopted fixed cycle controller is compared with others.

  • Tele manipulator is distingushed from industrial robot by iterating same specified work. Manipulator operator is included in control loop for controlling the telemanipulator because he decide directly during the work and order controllabily reducing the modelling error of telemanipulator which depend on the PID controller. But position-force control method of bidirectional control impose unsafety of vibiration and Analytic Hierachy Method can stabilize for reducing nonlinear modelling error by expert operator because of transformation empirical control rule to linear model.

  • The main purposes of this study were eliciting the planning contents and indices that is necessary to consider the physical part of public space, the side of service users and coherent side for improving public service. After then it analyzed the importance in both civil servants and practical officials side. For this public space planning topics and indicators by FGI (Focus Group Interview) derived through and through expert questionnaires Analytic hierarchy (AHP: Analytic Hierachy Process) were analyzed by conducting importance. A result, the priority of public space as a park planning index was found in the case of privately owned public space, public pedestrian pathways, public open space, public facilities land, the park is located, and the most important characteristics of the road, if the public transport association the most important thing is derived. In order to enhance the public good public space and location for easy access to the consideration of whether the plan should be. Therefore this work will be the fundamental materials to make some of farther policies related with the development of public interest of private-public spaces.

  • Many cut slopes are located along national roads, there were the collapse of cut slopes. In this study, the weights for condition evaluation of rock slopes was calculated using the entropy method and analytic hierachy process(AHP) method. The entropy analysis was performed using 95 cut slope data, and the AHP analysis was performed by a questionnaire to several expert. The weights based on analysis results were compared with evaluation weights of existing standard. As a result of this study, there was the difference of weights among the analytical methods. Later on, if this study's results is used to improvement current evaluation weights, it will be possible to perform the reliable condition evaluation.

  • 원거리에서 로봇 핸드를 제어하는 일은 어려운 일이다. 이를 WWW 데이터를 이용 데이터의 불분명확한 점을 사용하여 데이터가 덜 명확한 점이 있더라도 이를 제어 시스템의 데이터로서 사용할 수 있는 점을 이용하여 원거리에서 데이터를 WWW를 이용하여 수신하고 이를 좀더 발전시켜 로봇 제어를 할 수 있겠끔 데이터의 유동성을 보장하는 계층적 분석 방법에 접목시켜 로봇 제어를 할 수 있겠끔 하였다. 불분명확한 제어 데이터를 사용하는 대신 계층적 알고리즘을 사용하여 이를 보완 할 수 있는 보완 시스템을 구성하였다라고 말할수 있다. 단순한 WWW데이터 만으로 제어가 되지 않는다는 것을 확인하고 이를 계층적 분석 방법에 사용하므로써 보강할수 있는 점을 확인하고 WWW데이터를 사용하지 않는 방법과도 결과를 비교 검토한다.
