“…When the agents share all their knowledge before collective action, the problem can be stated as a multi-objective optimization problem [7]. When the number of actions is very large the resolution of this optimization problem clearly raises a combinatorial problem [10]. In the case of cooperative agents, where only partial knowledge is shared a debate model replaces the multi-objective optimization problem [8].…”

We consider the situation where a group of agents is involved in the achievement of a common goal. Each agent owns a set of actions that are partial solutions for the problem to be solved. Different agents may have the same actions. In order to decide which action to select from the various agents, actions are assessed using a set of attributes. These attributes measure the extent to which the actions satisfy the common objective. The problem of action selection becomes more complex if we consider that agents do not necessarily know each others' actions, which complicates the coordination of joint actions. Interactions between agents may be affected by antagonistic personal interests. The more actions are selected from an agent, the greater his/her budget. Based on a Multiple Criteria Decision Analysis (MCDA) framework and a fuzzy model that links actions to the satisfaction of objectives, this paper examines the problem of collective selection of the necessary actions to achieve a goal. Only information necessary for the progress of the collective action is shared, and collective and personal goals coexist and are to be taken into account.

“…Recently, some works in MCDA exploit the preferences model, in particular those using Choquet integral, to estimate the expected gain when improving a product/system on a set of criteria [7] [8] [9]. The authors associate to any coalition of criteria an index named worth index that measures for any considered state of the product/system, the mean expected gain of all the possible improvements.…”

On which criteria design efforts have to be focused on when pursuing the improvement of a product so as to provide most satisfaction to customers? The answer cannot be so obvious at the earliest steps of the design process when available knowledge is still incomplete and vague. Moreover, the problem becomes more complicated when the decision maker has to express some sophisticated preferences on the set of solutions. In this paper we propose to contribute to this issue by proposing an original qualitative computation of the worth-index, the purpose of which is to estimate the mean expected gain in performance improvement on a set of interrelated criteria. An illustration is given in the mechatronics field.

The authors in [9] [10] [11] associate to any coalition of criteria an index named worth index that measures for any alternative, the mean of all the possible expected improvements w.r.t a subset of criteria. These models assume that all the improvements are equiprobable whatever their magnitude.…”

In a highly competitive and unstable environment, manufacturers must constantly improve their products to remain competitive and satisfy their customers while minimizing incurred costs and risk taking. At the early stages of (re-) engineering, performances forecasting of new product is complicated. Indeed, the impacts of any characteristic change on the product performance are not precisely known. Decisionmakers must thus identify the performances to be improved while limiting the engineering efforts spent on innovative upgrades. Although some theoretical worth indexes have been proposed in the multiple criteria literature to estimate the expectable gains when improving changes are planned, they generally rely on non-realistic assumptions on the achievability of the expected improvements. Based on multi-criteria decision analysis techniques and uncertainty theory, this paper proposes an extension of the worth index concept when the likelihood of the expected improvements is not precisely known as it is the case at the preliminary stages of design activities.
