A framework to specify a reactive and proactive management system

Industries, in a present context, must become more and more reactive. This reactivity depends on middle or long term tactical choices which have been carried out. Its efficiency implies a perpetual fitting from rules and parameters according to environment changes. It needs the implementation of a management system which we define as reactive and proactive. Such a management system must be characterized by a reactive behaviour, i.e. handling uncertainty and orders directly at operational level. It must also be characterized by a decision support system, the "proactive system", which can adapt orders, rules, and/or parameters fixed to the operational management system according to the environment analysis and fitting with manufacturing models. Implementing such a management system implies the development of learning systems, models for cause/effects analysis and parameters fitting.
