Using scheduling techniques to reorder work in workflow systems can improve the performance of the business processes enacted by these systems. But this research area is still under-explored. This paper presents preliminary results on applying scheduling techniques to workflow systems. It studies the performance of scheduling techniques in five scenarios composed of sequences of workflow activities using simulation. The scenarios are dynamic and have uncertainties on the processing times of the cases in each of their activities. These uncertainties are handled by the guess and solve approach, which consists of making a guess on these processing times and solving the resulting deterministic problem with a suitable technique. The techniques results are compared to those obtained by the FIFO rule and they show that it is a good practice to use other techniques than FIFO (the most used ordering policy on today's workflows) and that the guess and solve is a feasible approach at least when its error is bound to 30 Clique no link abaixo para buscar o texto completo deste trabalho na Web: Buscar na Web
