This paper presents MAIC a knowledge-based decision support system for the maintenance of chemical plant equipment. The main functions of the system are: - The management of information concerning the components of pieces of equipment together with the corresponding corrosion agents and critical factors for this component. - A case based reasoning and retrieval function to search the corrosion case database for similar cases. - Several knowledge-based functions to support the economic assessment of a technically feasible solution.

The last part of the paper describes the conceptual framework of the OPTRANS development environment which was used to develop MAIC and which gives it many of its interesting features.
