Abstract: In this paper, based on disruption management method, logistics
distribution vehicle routing problem with soft time-window changes considering disruptions is explored. Firstly, by analysing the customers' requirements characteristics and the disadvantage of rigid time window, the soft time-window constraint is considered and the corresponding mathematical model is also setup. Secondly, according to the disruption management method, disruption factors including customers' satisfaction, path offsets, total distribution cost for time-window changes are analysed and the method of disruptions measure which considers synthetically the customers, logistics service provider and driver is proposed. A disruption recovery model for the problems is put forward based on the reposition strategy. Thirdly, in order to solve this multi-objective model, an artificial bee colony (ABC) which can optimise this NP-hard problem is developed. Finally, a numerical simulation experiment is used to verify this model and algorithm. The results illustrate the effectiveness of ABC in solving this problem. |

Abstract: Service management has been an important issue for many companies,
especially for service-based companies. This paper studies a routing problem that is usually faced by on site service companies. This type of company continuously receives orders during its working hours. In order to maximize the number of customers served and minimize the customer waiting time, the service team is responsible for determining which orders should be served during the ongoing working period and which orders should be served in the following working period. This paper represents this problem as a dynamic vehicle routing problem (DVRP). The proposed DVRP model also considers the uncertain service time using fuzzy theory. Furthermore, an algorithm using an improved fuzzy ant colony system (ACS) is proposed in order to solve the proposed model. The proposed algorithm embeds a cluster insertion algorithm into the ACS algorithm. The proposed algorithm is validated using some benchmark datasets. The results show that the proposed algorithm performs better than the previous fuzzy-ACS algorithm without cluster insertion algorithm. In addition, further sensitivity analysis is also presented to derive more information about the model and the proposed algorithm for application to real-world problems. (C) 2016 Elsevier Inc.

Abstract: The combination-vehicle attributes of vehicle routing problems are
additional characteristics that aim to consider more effectively the specificities of real logistics applications. Because various combination truck situations exist, the combination truck routing problem (CTRP) is supported by well-developed literature, especially with respect to the truck and trailer routing problem (TTRP), the rollon-rolloff vehicle routing problem (RRVRP), the tractor and semitrailer routing problem (TSRP), and a variety of heuristics. This article first reviews the three primary forms of the CTRP, providing a survey of problem foundations and heuristics for the TTRP, the RRVRP and the TSRP. Next, this report takes a closer look at comparing the three forms of the CTRP. The TTRP aims to efficiently apply trailers that can attach/detach trucks easily to serve less-than-truckload shipping, and the RRVRP and the TSRP aim to attain high use rates for tractors in different full truckload shipping practices. The three forms of the CTRP share a number of common features. In particular, most of the formulations and heuristic strategies developed for specific problems share many similar characteristics. The CTRP is an extremely rich and promising operations research field. More general formulations and more general-purpose solvers are necessary to address practical combination truck routing applications efficiently and in a timely manner. (C) 2016 The Authors.

Abstract: This study describes a single phase algorithm for the fixed destination
multi-depot multiple traveling salesman problem with multiple tours (mdmTSP). This problem widely appears in the field of logistics mostly in connection with maintenance networks. The general model of the technical inspection and maintenance systems is shown in the first part, where the solution of this problem is an important question. A mathematical model of the system's object expert assignment is proposed with the constraints typical of the system, like experts' capacity minimum and maximum and constraints on maximum and daily tours of the experts. In the second part, the developed evolutionary programming algorithm is described which solves the assignment, regarding the constraints introducing penalty functions in the algorithm. In the last part of the paper, the convergence of the algorithm and the run times and some examination of the parallelization are presented. (C) 2014 Elsevier Inc. All rights reserved. |

Abstract: The Clustered Vehicle Routing Problem (CluVRP) is a variant of the
Capacitated Vehicle Routing Problem in which customers are grouped into clusters. Each cluster has to be visited once, and a vehicle entering a cluster cannot leave it until all customers have been visited. This paper presents two alternative hybrid metaheuristic algorithms for the CluVRP. The first algorithm is based on an Iterated Local Search algorithm, in which only feasible solutions are explored and problem-specific local search moves are utilized. The second algorithm is a hybrid genetic search, for which the shortest Hamiltonian path between each pair of vertices within each cluster should be precomputed. Using this information, a sequence of clusters can be used as a solution representation and large neighborhoods can be efficiently explored, by means of bi-directional dynamic programming, sequence concatenation, and appropriate data structures. Extensive computational experiments are performed on benchmark instances from the literature, as well as new large scale instances. Recommendations on the choice of algorithm are provided, based on average cluster size. (C) 2014 Elsevier Ltd. All rights reserved. |

Abstract: In this work we consider the generalized vehicle routing problem with
stochastic demands (GVRPSD) being a combination of the generalized vehicle routing problem, in which the nodes are partitioned into clusters, and the vehicle routing problem with stochastic demands, where the exact demands of the nodes are not known beforehand. It is an NP-hard problem for which we propose a variable neighborhood search (VNS) approach to minimize the expected tour length through all clusters. We use a permutation encoding for the cluster sequence and consider the preventive restocking strategy where the vehicle restocks before it potentially runs out of goods. The exact solution evaluation is based on dynamic programming and is very time-consuming. Therefore we propose a multi-level evaluation scheme to significantly reduce the time needed for solution evaluations. Two different algorithms for finding an initial solution and three well-known neighborhood structures for permutations are used within the VNS. Results show that the multi-level evaluation scheme is able to drastically reduce the overall run-time of the algorithm and that it is essential to be able to tackle larger instances. A comparison to an exact approach shows that the VNS is able to find an optimal or near-optimal solution in much shorter time. |

Abstract: In this paper, we describe a hybrid approach based on the use of genetic
algorithms for solving the Clustered Vehicle Routing Problem, denoted by CluVRP. The problem studied in this work is a generalization of the classical Vehicle Routing Problem (VRP) and is closely related to the Generalized Vehicle Routing Problem (GVRP). Along with the genetic algorithm, we consider a local-global approach to the problem that is reducing considerably the size of the solutions space. The obtained computational results point out that our algorithm is an appropriate method to explore the search space of this complex problem and leads to good solutions in a reasonable amount of time. |

Abstract: This study presents new exact algorithms for the clustered vehicle
routing problem (CluVRP). The CluVRP is a generalization of the capacitated vehicle routing problem (CVRP), in which the customers are grouped into clusters. As in the CVRP, all the customers must be visited exactly once, but a vehicle visiting one customer in a cluster must visit all the remaining customers therein before leaving it. Based on an exponential time preprocessing scheme, an integer programming formulation for the CluVRP is presented. The formulation is enhanced by a polynomial time graph reduction scheme. Two exact algorithms for the CluVRP, a branch and cut as well as a branch and cut and price, are presented. The computational performances of the algorithms are tested on benchmark instances adapted from the vehicle routing problem literature as well as real-world instances from a solid waste collection application. |

Abstract: The vehicle routing problem (VRP) is one of the most explored
combinatorial problems in operations research. A very fast and simple algorithm that solves the VRP is the well known Clarke-Wright savings algorithm. In this paper we introduce a new way of merging routes and the corresponding formula for calculating savings. We also apply the enhanced merging to develop a new heuristic -Extended Savings Algorithm (ESA) that dynamically recalculates savings during iterations. Computational results show that, on average ESA gives better solutions than the original savings algorithm. Implementing randomization of some steps of our heuristic we obtained even better results which competes with more complex and well known heuristics. The ESA is further used to generate good routes as part of a setcovering- based algorithm for the Capacitated VRP (CVRP). The numerical results of our experiments are reported. (C) 2013 Elsevier Inc.

Abstract: The generalized vehicle routing problem (GVRP) is a natural extension of
the classical vehicle routing problem (VRP). In GVRP, we are given a partition of the customers into groups (clusters) and a depot and we want to design a minimum length collection of routes for the fleet of vehicles, originating and terminating at the depot and visiting exactly one customer from each group, subject to capacity restrictions. The aim of this paper is to present an efficient hybrid heuristic algorithm obtained by combining a genetic algorithm (GA) with a local-global approach to the GVRP and a powerful local search procedure. The computational experiments on several benchmark instances show that our hybrid algorithm is competitive to all of the known heuristics published to date. (C) 2012 Elsevier B.V.

Abstract: The vehicle routing problem with trailers and transshipments (VRPTT) is
a recent and challenging extension of the well-known vehicle routing problem. The VRPTT constitutes an archetypal representative of the class of vehicle routing problems with multiple synchronization constraints (VRPMSs). In addition to the usual task covering constraints, VRPMSs require further synchronization between vehicles, concerning spatial, temporal, and load aspects. VRPMSs possess considerable practical relevance, but limited coverage in the scientific literature. The purpose of the present paper is to describe how several important types of VRPMSs, such as multi-echelon location-routing problems and simultaneous vehicle and crew routing problems, can be modelled as VRPTTs.

Abstract: The heterogeneous fixed fleet vehicle routing problem (HFFVRP) is a
variant of the standard vehicle routing problem (VRP), in which the vertices have to be served using a fixed number of vehicles that could be different in size and fixed or variable costs. In this article, we propose an integer linear programming-based heuristic approach in order to solve the HFFVRP that could be used as a complementary tool to improve the performance of the existing methods of solving this problem. Computational results show the effectiveness of the proposed method. (C) 2012 Elsevier Inc. All rights reserved. |

Abstract: The Multiple Vehicle Traveling Purchaser Problem describes a school bus
routing problem that combines bus stop selection and bus route generation. This problem aims at selecting a set of bus stops from among a group of potential locations to pick up students, and for designing bus routes to visit the selected stops and to carry the students to their school. We address a variation of this problem that considers certain constraints on each bus route, such as bounds on the distances traveled by the students, bounds on the number of visited bus stops, and bounds on the minimum number of students that a vehicle has to pick up. Since column generation methods can easily deal with constraints on the consumption of resources related to each column, such as the constraints on routes mentioned above, and these methods are an alternative to other approaches based on three index variable formulations which suffer from the drawback of symmetry, we propose a branch-and-price algorithm based on a set partitioning formulation for this problem. We also study, using an extensive computational experience, the impact of enriching our proposal with additional inequalities in a branch-and-cut-and-price algorithm, which has revealed the importance of supplementing our column generation algorithm with cuts to improve its performance.

Abstract: The incorporation of CO2 emissions minimization in the vehicle routing
problem (VRP) is of critical importance to enterprise practice. Focusing on the tractor and semitrailer routing problem with full truckloads between any two terminals of the network, this paper proposes a mathematical programming model with the objective of minimizing CO2 emissions per ton-kilometer. A simulated annealing (SA) algorithm is given to solve practical-scale problems. To evaluate the performance of the proposed algorithm, a lower bound is developed. Computational experiments on various problems generated randomly and a realistic instance are conducted. The results show that the proposed methods are effective and the algorithm can provide reasonable solutions within an acceptable computational time. |

Abstract: The incorporation of the minimization of carbon dioxide (CO2) emissions
in the VRP is important to logistics companies. The paper deals with the tractor and semitrailer routing problem with full truckload between any two depots of the network; an integer programming model with the objective of minimizing CO2 emissions per ton-kilometer is proposed. A two-stage approach with the same core steps of the simulated annealing (SA) in both stages is designed. The number of tractors is provided in the first stage and the CO2 emissions per ton-kilometer are then optimized in the second stage. Computational experiments on small-scale randomly generated instances supported the feasibility and validity of the heuristic algorithm. To a practical-scale problem, the SA algorithm can provide advice on the number of tractors, the routes, and the location of the central depot to realize CO2 emissions decrease. |
