“…Over the last fifteen years, the literature, in accordance with the industrial decision-makers' point of view, has provided many studies and analyses concerning the performance concept [Lebas (1995)], its expression [Berrah et al (2000)], the performance indicators (PI's) [Fortuin (1988)] and the performance measurement systems (PMS's) as tools for its measurement [Nudurupati et al (2011)], [Neely et al (1995)], [Nair (2006)]. More particularly, we proposed in previous works [Berrah et al (1998)] to define the performance expression by a function P , such that ) , (…”

This article deals with the use, for industrial decision-making, of performance expressions that are provided by performance indicators and performance measurement systems. Two kinds of expression are distinguished in this sense: the performance measure on the one hand, and the performance evaluation on the other hand. While the performance measure identifies the achievement degree of the assigned objective, the performance evaluation handles the judgement of the decision-maker with regards to the obtained result. We focus in this study on the definition of a particular performance evaluation mechanism, which consists on a fuzzy symbolic handling of performance measures. Structural objective break-down that allows decision-makers to define the links between strategic, tactical and operational levels is the considered framework. We assume that performance measures are expressed at the operational level, for local control purposes, and look for translating them into performance evaluations, making them useful for the tactical decision-making. Performance measures are defined under numerical values. Fuzzification and defuzzification approaches are used in order to describe these values in linguistic terms, such as bad, medium or good. Symbolic items are also proposed. Some illustrations are presented, extracted from a case study which has been carried out in the Bosch Rexroth S.A. Company.

“…Elementary objectives are those objectives that are not considered through their break-down. Elementary expression is the result of a comparison between the objective and the measure [28], [29]. A comparison function generalises, to some extent, the idea of metrics understood in its mathematical sense, that is, a function which defines a distance between two elements of a set 1 .…”

International audienceExpressing the performance of industrial companies is an important feature for their continuous improvement. As the performance concept refers to the objective one, our idea is to relate the performance expression mechanism to that of the objective declaration. We propose a variable tree framework to describe the break-down of objectives and the expression of the performances, highlighting the multicriteria aspect of both the performance and the objectives. Moreover, the temporal aspects of the objective declarations are emphasised, leading to the introduction of both the objective and the performance temporal trajectories. Such trajectories take into account the whole of the temporal horizon that is associated with the achievement of the objective. The link between the provided trees and trajectories is established through the elementary objective notion which corresponds to the leaves of the trees. A conventional recursive depth-first search algorithm is applied to the variable tree for the computation of the corresponding performances, at any considered milestone of the temporal horizon. Finally, the overall throughput time of the hydraulic cylinders manufacturing line of the Bosch Rexroth Company is considered to illustrate the proposed ideas
