DECOMPOSITION AND COORDINATION FOR MULTIOBJECTIVE COMPLEX SYSTEMS

Abstract. Complex systems are modeled as collections of multiobjective programs each representing a subproblem (a subsystem or component) of the overall system. The sub-problems interact with each other in various ways adding to the complexity of the overall problem. Since the calculation of efficient sets of these complex systems presents a challeng-ing problem, it is desirable to decompose the overall system into component multiobjective programs that are more easily solvable and then construct the efficient set of the overall system. Selected cases of complex system are presented and relationships between their efficient sets and the efficient sets of their subproblems are given
