Abstract

A specification for a production cell is developed using the design method Focus. The specification comprises both the components of the production cell and the corresponding control programs. This work investigates the suitability of a rule system for the stepwise refinement of distributed systems in an assumption/commitment style. As a running example we consider the elevating rotary table of a production cell. Besides descriptive and constructive specifications for this component an executable simulation program in a functional language is presented. All design steps except the final transformation to an executable program are proven correct.
