The number of independent and interdependent freight actors (firms), the complex supply chain structures between them, and the sensitivity of shipment data are some reasons that the modeling of freight traffic is lagging its public and private transit counterparts. Expand

We present a tabu search algorithm capable of generating multiple patrol routes for an estate's security guards. Expand

The main thrust of this study is the operational scheduling of the continuous coal handling and blending processes when considering multiple, and sometimes conflicting, objectives. Expand

We present a multi-objective fuzzy-stochastic inventory model for the military.The model determines the minimum stock level and order quantity for a single item.The reliabilities of the model and two well known inventory models are compared. Expand

This paper is on fuzzy stochastic optimisation, an area that is quickly coming to the forefront of mathematical programming under uncertainty. Expand

In evolutionary algorithms, agents’ genotypes are often generated by more or less random mutation, followed by selection based on the fitness of their phenotypes. Expand

This paper evaluates four constructive heuristics capable of computing feasible solutions for the Mixed Capacitated Arc Routing Problem under Time Restrictions with Intermediate Facilities with application in municipal waste collection. Expand
