Bi-objective decision support system for routing and scheduling of hazardous materials

چکیده
This paper presents a Pareto-based bi-objective optimization of hazardous materials vehicle routing and scheduling problem with time windows and shows its application to a realistic hazardous material logistics instance. A meta-heuristic solution algorithm is also proposed, which returns a set of routing solutions that approximate the frontier of the Pareto optimal solutions based on total scheduled travel time and total risk of whole transportation process. It works in a single-step fashion simultaneously constructing the vehicle route and selecting the optimal paths connecting the routed locations from a set of non-dominated paths obtained in terms of travel time and risk value. 2014 Elsevier Ltd.

Developing a Bi-level Objective Model of Risk-Cost Trade-off for Solving Locating-Routing Problem in Transportation of Hazardous Material
Allocating and routing problems in the field of transportation engineering are generally solved using the objective function of minimizing transport cost. Transport risk is a main concern in hazardous material transportation, mainly dependent on the vision of decision makers (national and/or local authorities). In this research work, a trade-off approach has been proposed to determine the safes...
متن کاملA Bi-Objective Green Truck Routing and Scheduling Problem in a Cross Dock with the Learning Effect
We present a bi-objective model for a green truck scheduling and routing problem at a cross-docking system. This model determines three key decisions at the cross dock: (1) defining a sequence and schedule of inbound trucks at the receiving door, (2) specifying a sequence and a schedule of outbound trucks at the shipping door, and (3) determining the routes of the outbound truck while serving c...

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 کاملBi-objectives Approach for a Multi-period Two Echelons Perishable Product Inventory-routing Problem with Production and Lateral Transshipment
In this study, a two echelons supply chain system in which a supplier is producing perishable product and distribute it to multiple customers is considered. By allowing lateral transshipment mechanism, it is also possible to deliver products to some customers in some periods in bulk, then customers using their own vehicle to transship goods between each other seeking further reduction in the ov...
