Scheduling railway freight cars
It is dif®cult to allocate the freight cars and to determine how to load the several varieties of goods into them. In order to improve ef®ciency, a knowledge-based system (KBS) is developed and integrated into the existing railway information system. This paper introduces the development of the system and the framework in which the KBS are integrated into the existing system environments. Under...
متن کاملA Comprehensive Approach for Railway Crew Scheduling Problem (Case Study: Iranian Railway Network)
The aim of this study is to propose a comprehensive approach for handling the crew scheduling problem in the railway systems. In this approach, the information of different railway trips are considered as input and the problem is divided to three separated phases. In phase I, we generate all feasible sequences of the trips, which are named as the pairings. A depth-first search algorithm is deve...
متن کاملTwo Mathematical Models for Railway Crew Scheduling Problem
Railway crew scheduling problem is a substantial part of the railway transportation planning, which aims to find the optimal combination of the trip sequences (pairings), and assign them to the crew complements. In this problem, each trip must be covered by at least one pairing. The multiple-covered trips lead to impose useless transfers called “transitions”. In this study, a new ma...
متن کاملRail-Freight Crew Scheduling with a Genetic Algorithm
This article presents a novel genetic algorithm designed for the solution of the Crew Scheduling Problem (CSP) in the rail-freight industry. CSP is the task of assigning drivers to a sequence of train trips while ensuring that no driver’s schedule exceeds the permitted working hours, that each driver starts and finishes their day’s work at the same location, and that no train routes are left wi...
متن کاملImprovement of Column Generation Method for Railway Crew Scheduling Problems
The railway crew scheduling problem is to determine an optimal crew assignment to minimize the number of crews required to cover all of railway assignment satisfying several crew working constraints. The problem can be formulated as a huge set covering problem. Column generation method is commonly used to solve the railway crew scheduling problem. Conventional column generation method has a sho...
