The use of expert systems in the design of multi-echelon production distribution systems

Strategic decision making within multi-echelon production distribution systems is a difficult task due to the complex chain structures and inherent operating uncertainties of such systems. Hence there is a need for the application of expert systems methodology in this field.This paper reviews an approach in which industrial dynamics modelling techniques are used to simulate the dynamic behaviour of target systems over specified time horizons. Subsequently, control design techniques are utilised for performance sub-optimisation in order to generate a scenario-oriented knowledge base. A method is also presented for optimised design selection, based on interactive management performance objectives. Mutually conflicting objectives both within and between sub-systems in a multi-echelon production distribution system are also resolved as part of the optimised design. It is felt that such techniques are key components in an expert system for improving the design of high volume process production and distribution chains.
