Effective Team Formation in Workflow Process Context

With the purpose of improving the efficiency to accomplish a business process, how to form a multi-role collaborative team is a valuable research in the field of workflow. In this paper, based on the information about personal expertise and handover relations mined from event-log, we model the problem with Hidden Markov Models (HMM), then we use Viterbi algorithm to solve the problem. Finally we carry out experiments on actual data-set released by BPIC 2012 to evaluate the performance of our algorithm. The result shows we achieve at least 12% improve in the average efficiency of actual situation. Compared with the strategy only consider communication cost, our algorithm achieve a significant increase in efficiency (at most 408%), with a slight increase in communication cost (6.3%).
