A product-driven system approach for multilevel decisions in manufacturing planning and control
Résumé
Decision-making in Manufacturing Planning and Control Systems uses processes that
consider several levels of product aggregation and different time horizons. Decisions
rendered on each level do not always have similar goals. The problem is that
building Intelligent Manufacturing Systems (IMS) involves coordinate decisions on
different levels to achieve a common objective. There is no current research on IMS
regarding coordination among decision levels in Product-driven Control Systems,
hence simulations of the planning and control processes should be conducted to analyze
the behavior of multilevel objectives. Accordingly, in this paper a simulation
model gives account of different coordination issues between tactical and operational
levels. At the tactical level, production plans are generated by an Advanced Planning
and Scheduling system, whereas at the operational level, a distributed decision rule
is used. The whole simulation makes decentralized decisions that are managed by
production lots represented by holons. Results for our simulation indicate that
coordination among active lots is capable of making effective multilevel distributed
decisions when compared with conventional approaches.
