Abstract
Most control systems of flexible production cells have a hierarchical structure. They become very complicated and difficult to maintain and modify when the underlying production cells grow in size and complexity. Moreover, they are characterized by a relatively high sensitivity to failures. As opposed to that, heterarchical control systems are flexible, modular, easy to modify, and to some extent fault tolerant. In this paper, a heterarchical control system of a flexible production cell is formally specified in the CSP-based language chi . This language is well suited for the description of autonomous components cooperating with each other by exchanging information
