  • 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.

  • 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.

  • 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.

  • A magnetically levitated vehicle (Maglev) system is under commercialization as a new transportation system in Korea. The Maglev is operated by an unmanned automatic control system. Therefore, the plan of train operation should be carefully established and validated in advance. In general, when making a train operation plan, statistically predicted traffic data is used. However, a traffic wave often occurs in real train service, and demand-driven simulation technology is required to review a train operation plan and service quality considering traffic waves. We propose a method and model to simulate Maglev operation considering continuous demand changes. For this purpose, we employed a discrete event model that is suitable for modeling the behavior of railway passenger transportation. We modeled the system hierarchically using discrete event system specification (DEVS) formalism. In addition, through implementation and an experiment using the DEVSim++ simulation environment, we tested the feasibility of the proposed model. Our experimental results also verified that our demand-driven simulation technology can be used for a priori review of train operation plans and strategies.

  • 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.

  • In this paper, the analysis methods of available information are reviewed and it is elicited to the method of which the analysis results are applied to the Autonomous Decentralized Train Management System for the optimization at the point of the route control time and for making the efficiency shunting plan in the Autonomous Centralized Station Operation Control System. As the statistics and estimated information which are got through the utilizable information analysis are applied for the automatic route control function and the shunting plan management of the station operation control system, it is possible to use efficiently the station information by the autonomous route control system. And as the exact forecast information needed for the shunting plan establishment and the operation is provided to the operator, it is established to the efficient train operation plan.
