This paper presents a new and efficient heuristic to solve the multi-product, multi-stage, sequencing, lot sizing and scheduling problem. The problem addressed is that of making sequencing, lot sizing and scheduling decisions for a number of products manufactured through several stages in a flow...

An important activity of the Air Operation Center (AOC) is the elaboration, mitigation and evaluation of different Courses of Actions (CoAs) in order to respond to emergency situations. Defense Research Establishment Valcartier (DREV) initiated a research activity to provide the AOC Commander...

In this paper, a multicriterion ranking procedure based on distance between partial preorders is proposed. This method consists of two phases. In the first phase, the decision maker is asked to rank alternatives with a preorder (complete or partial) for each criterion and provide complete or...

The multicriterion analysis under uncertainty (in the sense of probability) has so far been treated nearly exclusively in the theory of the multiattribute utility framework that proposed multicriterion aggregation procedures that belong to the unique criterion synthesis approach. Yet, there is...

We address the problem of choosing the cutting speed of a flexible machine-tool to minimize the expected total processing time. The tool life is a random variable with a known distribution. Tool failures cause a set-up time and thus increase processing time. We assume the coefficient of...

In this paper a Superiority and Inferiority Ranking (SIR) method is proposed. This new method uses two types of information, the superiority and the inferiority information, to derive two types of flows, the superiority flow and the inferiority flow, by which the set of alternatives are ranked...

Dans ce papier, nous proposons une methode interactive d'aide a la decision de groupe en contexte multiobjectif qui utilise l'agregation a priori et a posteriori des preferences.
