An Approach to Constructing Business Process in Wireless Migrating Workflow Environment

In order to support process construction in wireless migrating workflow system, this paper presents an approach based on task components for resource-limited executing environment. First, we propose a business process construction model based on the idea that the process logic is separated from the process instances, and then abstract the process generation as a resource-constrained combinatorial optimization problem whose objective is to maximize the QoS of the whole process. For the problem solving, a novel discrete differential evolution (DDE) algorithm is detailed and the simulation experimental results demonstrate the effectiveness of the algorithm.
