This paper presents a Rotem's methodology for the establishment of train operation plan in Railway system. Train operation plan is the key prior plan to proceed the design of the civil and E&M relevant subsystem. But, due to the limitation of the environmental and project condition, common consensus to the key factors which make up the operation plan have not been accomplished. So, as a result of this comparative review for the general approaching method of train operation plan and application status of the major key factors being performed by Rotem, we will get the opportunities to improve the accuracy of the train operation plan.

It is very difficult to find optimal train operation plan when analyzing the economic investment using traditional railroad travel demand estimation method. Train operation plan depends on travel demand and vice versa. To solve this problem, this study suggests a demand estimation method to address an optimal train operation scheme with the modal spilt using initial train operation plan and trip assignment.

The purpose of this study is to analyze the actual condition of the already established rural theme park, draw the weak and strong points, and come up with an efficient performance plan for Changwon Persimmon Theme Park through the benchmarking of the best overseas case. According to the analysis, it is necessary to introduce a facility and a program for family customers as a plan for promoting Changwon Persimmon Theme Park. It is required to secure safety through public operation and management, improve scalability of the facility through the establishment of multi-functional complex facility, and come up with a plan for operating a special program associated with local resources. Therefore, this study drew three activation factors: the establishment of operation and management system, the development of operation contents by facility, and the establishment of operation in each area. First, to establish the operation and management system, it is necessary to classify the organization of the theme park into the operation business area and into operation & management area by job function. Secondly, it is necessary to establish a special program in consideration of space and facility, suggest a differentiated plan for operation contents, and create a facility operation plan and program for Changwon Persimmon Theme Park. Lastly, to operate and manage Changwon Persimmon Theme Park smoothly, it is necessary to set the theme park space as open collaboration space which the local residents can share and participate in by avoiding the conventional administration-based business performance and operation. This study suggested the plan for establishing an operation and management system for Changwon Persimmon Theme Park and its operation, the establishment of a special program, a business performance strategy, and the use of internal and external spaces of the theme park.

The current electrical safety plan developed for the national electricity system has been playing an important role in handling a variety of electrical accidents. However, it can be more effective to prevent or reduce those accidents if a preventive electrical safety plan is available. In this paper, an approach to developing the safety plan is described. We first discuss the contents that should be included in the plan. Noting that an effective plan requires the system level consideration of all the factors affecting the safety issues, an operation concept document (OCD) is considered. The OCD can allow us to understand the behavior of the safety system based on the operation environment, the system functions, the performance requirements, all at the system level of the safety system. Thus, the OCD can be useful in developing the safety plan. A detailed description then follows on how the OCD is developed for the electrical safety system under study. Finally, we discuss how the developed OCD can be used in deriving the preventive electrical safety plan.

In railway system, the transportation plan corresponds to master plan for transport services. This service plan must be constructed to minimize operational cost or maximize revenue considering transportation demands and resource capacities in the operation company, and includes several sub-planning activities such as train operation frequency plan, train (schedule) plan, train capacity assignment plan, and rolling stock requirement plan. In this paper, we present profitability evaluation system for current transportation plan. The proposed system can be used for evaluating profitability by estimating train service revenue considering customer demands.

연구목적: 본 연구는 최근 도입된 기능연속성계획과(COOP)과 기존의 국가기반체계보호계획(NIPP)을 비교·분석하여 양 제도의 보다 효율적인 운영대안을 마련하는 것을 목적으로 한다. 연구방법: 연구를 위해 양 제도의 기초자료를 수집하고, 내용적 측면과 절차적 측면으로 구분하여 비교·분석하였다. 또한, AHP를 활용하여 재난분야 전문가들을 대상으로 두 제도에 대한 효율적인 운영대안을 도출하였다. 연구결과: NIPP과 COOP은 내용적·절차적 측면에서 매우 유사한 제도임을 알 수 있었고, 재난관련 설문조사에서도 두 제도를 통합하여 운영하는 것이 더 효율적이고 효과적인 운영방안이라는 결과를 도출하였다. 결론: 본 연구를 통해 최근 도입된 기능연속성계획(COOP)이 국가기반체계보호계획(NIPP) 보다 대상범위가 더 넓고 포괄적이며, 핵심기능의 연속성을 확보하는 시스템 구조를 갖고 있음을 알 수 있었다. 관련법령 정비 등을 통해 NIPP을 COOP으로 포함시키는 제도통합이 이루어 진다면 보다 효율적이고 강화된 국가안전망이 실현될 수 있을 것으로 본다.

This paper describes the simulation study which evaluates operation plans of container terminal. The operation plans of container terminal consist of berth plan, load plan, unload plan, yard plan, and equipment plan. It is discussed how to apply the simulation method to evaluate those plans that are interrelated with each other. This paper also deals with the assignment and coordination problems of container-handing equipment such as container cranes, transfer cranes, yard tractors, and trailers used in the transportation of containers. Simulation analysis is bases on data about plans from the operation planning system through an interface program. It is discussed what we should got the statistics about container-handing equipment in the simulation.

In this paper, Optimal operation plan through load analysis of industrial end-user is suggested. It calculated economic feasibility of ESS with detailed power lad analysis and conditions. Generally, if the latest maximum power is less than 30% of contracted power, it can not be peak shaving operation plan. and if the peak load level stays stead for 24 hours, it is difficult peak shaving for ESS. In addition to, When the peak load is occurred in summer or winter, a hybrid operation method combining the peak shaving plan and the time shift method is proposed. Therefore, When ESS is installed in industrial electrical customer, it is achieved best effect through the optimal operation plan.

철도운영기관은 수송수요예측과 열차차량의 수송능력을 토대로 수송계획을 세우고 이에 따른 열차운행계획을 수립한다. 열차운행계획을 통해 열차 운행간격이 조정되어 열차운행시간표(열차다이아)가 작성되고, 열차운행에 사용되는 열차의 차량운영계획이 수립된다. 열차운영기관에서는 열차 운영관리의 효율성을 높이기 위해 다이아에 편성되어진 열차들의 승무인원을 판단하고 배치하는 승무일정계획을 수립해야 한다. 본 연구에서는 승무일정계획 문제인 승무다이아 작성단계에 제약조건을 만족하는 이웃해 탐색기법을 적용하여 승무 계획의 효율적 관리가 가능하도록 하는 방법론을 제시한다. 연구에서 제시한 방법론에 의해 생성된 승무 다이아는 실제 운영하는 열차시간표를 대상으로 기존 승무다이아와 결과 값을 비교하여 제시된 방법론의 효율성을 검증하였다.
