Because of the transmission of disease producing parasites to man and animals and the nuisance caused by bites from adult black flies, they are the object o...

This paper presents a model for the optimization of productivity in a steel plant comprised of four arc furnaces and three continuous casting machines and su...

The vehicle routing problem (VRP) involves the design of a set of minimum cost routes, originating and terminating at a central depot, for a fleet of vehicl...

The two-dimensional cutting-stock problem consists of laying out a specified list of rectangular pieces on rectangular sheets, in such a way as to minimize t...

The vehicle routing problem (VRP) involves the design of a set of minimum cost routes for a fleet of vehicles which services exactly once a set of customers...

Schedule compression is a major concern in project management. We propose an extension of the classical crashing model to include the managerial practice of...

This paper shows how the subtour elimination constraints developed by Miller, Tucker and Zemlin for the traveling salesman problem can be improved and exten...

We consider projects represented by a PERT network, with convex cost-of-time functions on individual activities, and we show the existence of an efficient m...

The multiple vehicle many-to-many routing problem is presented in the context of a dial-a-ride system. It is solved by mini-clustering first and optimal ro...

In this paper, we present general formulations for the stochastic vehicle routing problem with capacity restrictions in which the <i>m</i> vehicle tours hav...

Given a weighted graph with profits associated with the vertices, the selective travelling salesman problem (or orienteering problem) consists of selecting ...

We present a dual algorithm to minimize a separable convex function under ratio constraints between variables. This minimization problem occurs when the dep...

This paper describes a family of stochastic location-routing problems which consist of simultaneously locating a depot among a set of potential sites, of det...

In this paper we analyze the problem of finding the trading area for a facility on a linear market. Given the objective of maximizing profit, we first build...

This paper examines a class of asymmetrical multi-depot vehicle routing problems and location-routing problems, under capacity or maximum cost restrictions. ...

In this paper, an extension of the classical scheduling problem is considered. It is assumed that tasks are processed on parallel processors, available at d...

Recently we have witnessed the development of a fast growing body of research focused on vehicle routing and scheduling problem structures with time window c...

Location-routing problems involve simultaneously locating a number of facilities among candidate sites and establishing delivery routes to a set of users in ...

This paper considers a vehicle routing problem with full loads and time limit constraints. This problem can be formulated as an asymmetrical travelling sale...

Hydraulic turbine runners are used in electricity generation. These consist of a cylinder around which are welded, at regular spacings, a number of blades w...
