For business processes, there are problems in collaborative design such as inadequate description
and poor flexibility. By analyzing features in a cloud workflow model in terms of concurrency, scalability,
collaborative, dynamic and compositability, a workflow model of three-dimensional distribution in space is
established. A Petri net with compositability, color and timing constraints is introduced into the process
modeling. A hybrid Petri net (HPN) model is designed, which can dispose the cloud workflow business
processes. Using the idea of stochastic Petri net, the process flow and efficiency are explained, performance of
the model is analyzed. Reachability of the model is verified. An optimization scheme is proposed to deal with
business conflicts and model decomposition.
