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...

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...

Telecom supply chains are subject to instabilities and uncertainties that make substantial the risks handled by the chain actors. This paper demonstrates that the exchange or sharing of reliable information improves both actors' and SC's performance. In particular, this paper presents a system...

In semiconductor manufacturing, machines are usually qualified to process a limited number of recipes related to products. It is possible to qualify recipes on machines to better balance the workload on machines in a given toolset. However, all machines of a toolset do not have equal uptimes and...

The current literature in the rail–truck intermodal transportation of hazardous materials (hazmat) domain ignores congestion at intermodal yards. We attempt to close that gap by proposing a bi-objective optimization framework for managing hazmat freight that not only considers congestion at...

В статье рассматриваются проблемы, возникающие при управлении предприятиями, входящими в холдинг. Автор показывает несовершенство методического аппарата,...

Concerns about energy supply security and climate change have been pushing world countries towards the promotion of renewable sources of energy and more sustainable liquid fuels. Initially indicated as the most viable solution within the transport sector, corn bioethanol is now incurring...

A fully integrated planning tool capable of undertaking an initial grid connection assessment for prospective renewable energy generators (REG) has been developed to support the Scottish Executive achieve their targets for renewable energy utilisation, and to assist the Scottish electric utility...

Measuring capacity is a major problem, especially in service organizations because of its complexity and the lack of research on this topic at these kinds of organizations. Therefore, the purpose of this article is to discuss a methodology for measuring the capacity of an university by focusing...
