Définition d’une expression temporelle de la performance des entreprises manufacturières

Abstract : Fifty years ago, the expression of industrial performance was Taylorian, mono criterion, and attached to the financial results of the company. Today, the performance has adopted both multi criteria and multilevel dimensions. More generally, such a performance is usually related to the achievement of overall objectives and is dedicated to control purposes, post Taylorian performances are thus expressed on the basis of comparisons between the fixed objectives and the corresponding measures. However, this performance is often statically expressed, generally at the final moment of the temporal horizon which is associated with the objective achievement. In this thesis, we propose a definition of the “temporal” performance, according to three performances: the instantaneous performance, the trend performance and the predictive performance. The fundamental assumption in our work consists of considering an objective as being a trajectory of what we call intermediate objectives, throughout a given temporal horizon. Instantaneous performance is expressed by the objective achievement at a given milestone of the temporal horizon. Such a performance relies on the comparison of the objective and the measurement of its achievement. Trend performance is the result of the comparison of the trend objective with the trend measurement. This performance provides information concerning the objective achievement. Predictive performance is defined at a given milestone of the temporal horizon, for a future milestone of this horizon. It is the result of the comparison of the intermediate objective of the considered future milestone with an estimation of measurement at this same future milestone. Moreover, a methodology for using these performances is proposed, based on a principle of aggregation, "in pairs", of the three temporal performances, which allows us to provide a single synthetic piece of information that is, to some extent, the performance of the objective trajectory. As a continuation of this definition step, we propose a qualitative formalization of these performances, based on the fuzzy subsets theory. Rules-based aggregations and linguistic descriptions are used in this. Finally, we illustrate these propositions with examples that are extracted from the OEE improvement project of the Fournier Company.
