Distribuição de tarefas em sistemas de workflow por meio da seleção induzida de recursos

Abstract

The assingment of tasks to resources of a workflow system is called task distribution. The task distribution is an important activity for workflow systems, because it is necessary to ensure that a task is performed by the appropriate resource in due time. There are several approaches to task distribution in workflow systems. This work innovates by using a Link Analysis technique applied to the task distribution. The Link Analysis is used to rank the result of a web query. The rank is performed by considering the relevance of the pages. This work presents the application of Link Analysis in the context of workflow task distribution. We have proposed a new task distribution algorithm (wf-hits) based on Link Analysis algorithm. We have compared wf-hits against other related ones. This comparison have considered quantitative and qualitative aspects. The experiments have shown that the use of wf-hits has improved workflow systems 25% in quantitative terms meanwhile the qualitative terms has maintained the same level of similar related works.
