This monograph coherently presents a series of research results on concurrent production systems. Before going into the details of concurrent production systems, the performance of a single system is discussed. Based on these considerations, it is explained how to estimate the efficiency of production systems programs and how to automatically determine efficient join structures. Parallel systems, multiagent production systems and the related control issues are investigated. Finally, a meta-level control architecture is applied to the construction of the multiagent system CoCo for public telecommunication network control.
