چکیده
s of the presentations, can be found at the following site: http://webpages.ull.es/users/saderyl/Coral.htm. The SADERYL project is based on a global understanding of the logistics chain and its requirements for an efficient management. The decision problems arising in the integrated management of the logistics chain can be classified as strategic, tactical, and operational problems. Within the SADERYL project, we have focused mainly on the strategic and tactical aspects, concerning routing, location, and combined location-routing problems. All these problems are of great economic interest and the use of combinatorial optimization-based packages for their management has proved to produce substantial savings. However, a much deeper understanding of these problems is needed to improve the quantitative tools that should be provided to the managers as a basis for making their decisions. Through CORAL 2003, we have tried to contribute to this objective with some papers giving more theoretical insights, modeling approaches, and heuristic and exact algorithms for these

Modelling and Solving the Capacitated Location-Routing Problem with Simultaneous Pickup and Delivery Demands
In this work, the capacitated location-routing problem with simultaneous pickup and delivery (CLRP-SPD) is considered. This problem is a more realistic case of the capacitated location-routing problem (CLRP) and belongs to the reverse logistics of the supply chain. The problem has many real-life applications of which some have been addressed in the literature such as management of liquid petrol...
متن کاملA Customized Bi-Objective Location-Routing Problem for Locating Post Offices and Delivery of Post Parcels
One of the most important problems for distribution companies is to find the best locations for depots and to find proper routes for transportation vehicles and to optimize supply network. This study intends to develop a model for the problem of location-routing in post offices. So, a new Bi-Objective Location-Routing Problem for Locating Town Post Office and Routing Parcels is defined. This pr...
متن کاملA Hybrid Heuristic Algorithm to Solve Capacitated Location-routing Problem With Fuzzy Demands
In this paper, the capacitated location-routing problem with fuzzy demands (CLRP-FD) is considered. The CLRP-FD is composed of two well-known problems: facility location problem and vehicle routing problem. The problem has many real-life applications of which some have been addressed in the literature such as management of hazardous wastes and food and drink distribution. In CLRP-FD, a set of c...
متن کاملInvestigating Zone Pricing in a Location-Routing Problem Using a Variable Neighborhood Search Algorithm
In this paper, we assume a firm tries to determine the optimal price, vehicle route and location of the depot in each zone to maximise its profit. Therefore, in this paper zone pricing is studied which contributes to the literature of location-routing problems (LRP). Zone pricing is one of the most important pricing policies that are prevalently used by many companies. The proposed problem is v...
متن کاملA Combined Stochastic Programming and Robust Optimization Approach for Location-Routing Problem and Solving it via Variable Neighborhood Search algorithm
The location-routing problem is one of the combined problems in the area of supply chain management that simultaneously make decisions related to location of depots and routing of the vehicles. In this paper, the single-depot capacitated location-routing problem under uncertainty is presented. The problem aims to find the optimal location of a single depot and the routing of vehicles to serve th...
متن کاملSolving a bi-objective location routing problem by a NSGA-II combined with clustering approach: application in waste collection problem
It is observed that the separated design of location for depots and routing for servicing customers often reach a suboptimal solution. So, solving location and routing problem simultaneously could achieve better results. In this paper, waste collection problem is considered with regard to economic and societal objective functions. A non-dominated sorting genetic algorithm (NSGA-II) is used to l...
