In this paper, we propose a modification of Benson’s algorithm for solving multiobjective linear programmes in objective space in order to approximate the true nondominated set. We first summarize Benson’s original algorithm and propose some small changes to improve computational...

Deterministic inventory theory provides streamlined optimization models that attempt to capture trade-offs in managing the flow of goods through a supply chain. We will consider two well-studied deterministic inventory models, called the one-warehouse multiretailer (OWMR) problem and its special...

Purpose – The aim of this paper is to develop and demonstrate an outsourcing decision model in which constraint resource prevents the throughput of the organization. Design/methodology/approach – An integrated model is proposed by incorporating the weighted product model (WPM) of AHP in...

Purpose – The purpose of this paper is to solve the problem of committing electric power generators (unit commitment, UC), considering network constraints. Design/methodology/approach – The UC is first solved with a local search based meta‐heuristic, following the assumption that all...
