摘要: A workflow describes the flow of activities of abusiness process. Petri nets are a powerful formalism in modeling workflows. Inmany situations, business processes are constrained by scarce resources. Thelack of resources can cause contention and slow down the execution of workflows.This presentation introduces a Petri net based approach for resourcerequirements analysis. The concept of resource-oriented workflow nets (ROWN) isintroduced. Resource requirements for general workflows can be done throughreachability analysis. More efficient algorithms for maximum and minimumresource requirements are developed for a class of well-structured workflows,in which when a task execution is started it is guaranteed to finish. For tasksthat may fail in the middle of execution, an equivalent non-failing task modelin terms of resource consumption is developed.
