A tabu search heuristic for the static multi-vehicle dial-a-ride problem

نویسنده

  • Gilbert Laporte
چکیده

This article describes a tabu search heuristic for the dial-a-ride problem with the following characteristics. Users specify transportation requests between origins and destinations. They may provide a time window on their desired departure or arrival time. Transportation is supplied by a fleet of vehicles based at a common depot. The aim is to design a set of least cost vehicle routes capable of accommodating all requests. Side constraints relate to vehicle capacity, route duration and the maximum ride time of any user. Extensive computational results are reported on randomly generated and real-life data sets. 2003 Elsevier Science Ltd. All rights reserved.

Improved Tabu Search Heuristics for Static Dial-A-Ride Problem: Faster and Better Convergence

Multi-vehicle routing has become increasingly important with the rapid development in autonomous vehicle technology. Dial-a-ride problem, a variant of vehicle routing problem (VRP), deals with the allocation of customer requests to vehicles, scheduling the pick-up and drop-off times and the sequence of serving those requests by ensuring high customer satisfaction with minimized travel cost. In ...

Parallel Tabu search heuristics for the dynamic multi-vehicle dial-a-ride problem

In the Dial-a-Ride Problem (DARP) users specify transportation requests between origins and destinations to be served by vehicles. In the Dynamic DARP, requests are received throughout the day and the primary objective is to accept as many requests as possible while satisfying operational constraints. This article describes and compares a number of parallel implementations of a tabu search heur...

A heuristic approach for multi-stage sequence-dependent group scheduling problems

We present several heuristic algorithms based on tabu search for solving the multi-stage sequence-dependent group scheduling (SDGS) problem by considering minimization of makespan as the criterion. As the problem is recognized to be strongly NP-hard, several meta (tabu) search-based solution algorithms are developed to efficiently solve industry-size problem instances. Also, two different initi...

A novel heuristic algorithm for capacitated vehicle routing problem

The vehicle routing problem with the capacity constraints was considered in this paper. It is quite difficult to achieve an optimal solution with traditional optimization methods by reason of the high computational complexity for large-scale problems. Consequently, new heuristic or metaheuristic approaches have been developed to solve this problem. In this paper, we constructed a new heuristic ...

A Hybrid Tabu Search and Constraint Programming Algorithm for the Dynamic Dial-a-Ride Problem

This paper introduces a hybrid algorithm for the dynamic dial-a-ride problem in which service requests arrive in real time. The hybrid algorithm combines an exact constraint programming algorithm and a tabu search heuristic. An important component of the tabu search heuristic consists of three scheduling procedures which are executed sequentially. Experiments show that the constraint programmin...
