The problem of dynamic control of Discrete Event Dynamic Systems (DEDS) is addressed in this paper as a. dynamic optimization problem: some resources must be allocated to the sys tem in order to optimize a. p erformance function which is assumed time-varying. The control scheme exploits a. state reconstruction al gorithm to compute an estimate of the performance for perturbed sample paths. The algorithm is based on the use of data. extracted from the observation of the system and allows to accurately reconstruct its state beha.vior, for resource allocations different from the nominal one. The proposed control scheme is then used for dynamic alloca tion of buffer capacities in manufacturing systems, such as Ka.nba.n systems. A pa.ra.llel implementation of the whole a.lgorithm is also mentioned.
