Large models can be decomposed into sub-models that can be refined semi-independently and executed in parallel. In this paper, we show how to introduce explicit control flow for the concurrent sub-models in the form of event schedules. We explore how schedules can be designed so that their application results in a correctness-preserving refinement step. For practical application, two patterns for schedule introduction are provided, together with their associated proof obligations. We demonstrate our method by applying it on the dining philosophers problem. date: 2011-06 date_type: published pagerange: 166-182 event_title: 15th International Refinement Workshop (associated with Formal Methods 2011) event_location: Limerick, Ireland event_dates: 20th June 2011 event_type: workshop refereed: TRUE official_url: http://eptcs.org/paper.cgi?Refine2011.11 citation: Boström, Pontus and Degerlund, Fredrik and Sere, Kaisa and Waldén, Marina (2011) Concurrent Scheduling of Event-B Models.
