Decision-making aiding for the improvement of an overall performance issued from a Choquet integral-based aggregation
Résumé
This article considers the improvement of the industrial performance in a multicriteria context. Subscribing to continuous improvements conventionally based on the Deming's wheel, decision-makers (DMs) need pieces of information leading them to plan and react according to the checked states. We focus more particularly in this study on the DM's requirements to choose for each improvement iteration, the priority elementary performance to have a significant improvement of the overall performance. Our approach is based on a Performance Measurement System model, with regard to an overall objective and its sub objectives. Given the elementary performances that are associated to the involved sub objectives, the model provides an overall performance by using the 2-additive aggregation operator of the Choquet integral (CI) family, which generalises common aggregation operators. This article considers the temporal sub-objectives determination, the so-called intermediary elementary expressions, through their impact on the overall performance improvement. Three indexes - overall, local and average - are introduced in order to quantify this impact. The propositions are applied to the business turn-over performance improvement of a SME company.
