Abstract : Decision-making in Manufacturing Planning and Control Systems uses processes thatconsider several levels of product aggregation and different time horizons. Decisionsrendered on each level do not always have similar goals. The problem is thatbuilding Intelligent Manufacturing Systems IMS involves coordinate decisions ondifferent levels to achieve a common objective. There is no current research on IMSregarding coordination among decision levels in Product-driven Control Systems,hence simulations of the planning and control processes should be conducted to analyzethe behavior of multilevel objectives. Accordingly, in this paper a simulationmodel gives account of different coordination issues between tactical and operationallevels. At the tactical level, production plans are generated by an Advanced Planningand Scheduling system, whereas at the operational level, a distributed decision ruleis used. The whole simulation makes decentralized decisions that are managed byproduction lots represented by holons. Results for our simulation indicate thatcoordination among active lots is capable of making effective multilevel distributeddecisions when compared with conventional approaches.
