Train timetabling, platforming, and network maintenance scheduling are three highly interdependent problems that crucial in the planning of railway operations, each is normally addressed separately. In this paper, we simultaneously optimize these for a high-speed comprised multiple lines stations. We model on mesoscopic level formulate 0–1 binary integer programming minimizes total train weight...

This paper describes how the MTR Corporation of Hong Kong made use of Artificial Intelligence (AI) and Web 2.0 technology to computerize and streamline daily maintenance scheduling. The application is called the Engineering Works and Traffic Information Management System (ETMS), an intelligent workflow system for maintenance scheduling. ETMS oversees over a thousand workers for railway maintena...

Well tamped ballast reduces track irregularities and increases travel safety and comfor...

The current state of the art in scheduling \point-to-point" trains in a railway network utilizes the principles of centralized decision-making. A point-to-point train refers to either a freight or a passenger carrying express train wherein the originating (A) and destination (B) stations are known a priori but the route between A and B may be ascertained dynamically based on a complex cost func...

Resource scheduling problems with incomplete information and environment changes have been studied for decades. The vast majority of the research efforts in the scheduling problems under uncertainty assume a central authority with a global objective of maximizing the resource usage. In real-life scheduling problems, in addition to the dynamic environment, sometimes conflicting interests of diff...

Abstract In this article, the user resource allocation and scheduling in a cell-free user-centric clustering network coherent transmissions is investigated. However, setup of not sufficient for multi-user transmissions, becomes difficult. To overcome aforementioned problem to provide fairness, an optimum algorithm with perfect scheduling, beam forming, radio frequency transmitter (RFT) proposed...
