We consider the extended economic production quantity (EPQ) problem when demand follows a Poisson process in a production system. A fixed lot sizing policy is implemented to minimize fluctuation of workload, and to smooth production planning and inventory control. The considered costs include...

We develop a model of budget allocation for permanent and contingent workforce under stochastic demand. The level of permanent capacity is determined at the beginning of the horizon and is kept constant throughout, whereas the number of temporary workers to be hired must be decided in each...

As ports have become key logistics nodes in global chains, port management of container operations has been experiencing radical changes. Moreover, the ramifications of the associated policy-making expand well beyond their own boundaries. The challenging managerial environment is further...

In this paper we describe a decision support system developed to help in assessing the need for various type of prison cells. In particular we predict the probability that a criminal has to be sent home because of a shortage of cells. The problem is modelled through a queueing network with...

This paper explores the notion of “capacity building” from the standpoint of the technological expertise needed for sustainable development policy analysis and execution. It argues that this definition is probably at the root of the concept since it captures the fundamental creativity of an...

This article employs a mathematical programming model to solve the capacity planning problem of international direct dialling (IDD) services. Our study involves allocating forecasted IDD demand traffic to destination countries via partner suppliers at minimum cost. To facilitate its use, the...

The analytic hierarchy process is combined with multi-objective mixed integer programming to determine the optimal allocation of a limited number of aircraft among a group of airlift users with varying levels of priority and length of usage. Canadian Forces airlift planners typically encounter...
