Negotiation based on constraints in cooperation

This paper presents some aspects of cooperation in organizations. In the first part, we present the importance to coordination processes within an organization. Indeed, the information perceived by the company no longer pertains to the realm of the repetitive, predictable and programmable. In this context of limited rationality, how can one define an efficient and acceptable decision coordination and distribution structure? We argue that the intervention of man in the decisional process remains inescapable on account of the limitations of the coordination process, and define several forms of cooperation between decision centers on an industrial site.In the second part, the assumption retained is that for the management of a production system the decision is made through a network of decision centers. The approach presented puts forward the development of decision and cooperation aid tools only exploiting the information contained in the constraints linking together the decision variables so as to highlight the degrees of freedom effectively available to the decision maker. Finally, we discuss about cooperation and power, where the power issue cannot be disregarded.

A graphical and ergonomic module for decisions of workload regulation and operations re-planning, in systems of discrete and diversified productions MARGE 1 and 2

This paper concerns the centre of decisions of workload regulation and operations re-planning, on an aggregated resource of operators team, or identical machines set. It may be situated between the upper planning centre which realises a first temporal distributing of operations according to orders due dates and manufacturing processes, and the lower scheduling centre which decides beginning dates and detailed resource allocations for the operations. Two interdependent modules, MARGE 1 and 2 (module aid for workload regulation, graphics and ergonomics) are presented.<<ETX>>
