摘要:

提前了解运行过程实例的趋势的能力,相对于不同的特征,例如预期的完成时间,将允许业务管理人员及时应对不期望的情况,以防止损失。因此,在管理流程时,准确预测正在运行的业务流程实例的未来特性的能力将非常有用,特别是在服务级别协议约束下。然而,做出如此准确的预测并不容易:许多因素可能会影响预测的特征。已经提出了许多方法来处理这个问题,但他们都假设的基础过程是平稳的。然而,在实际情况下,这种假设并不总是正确的。在这项工作中,我们提出了新的方法来预测剩余时间的运行情况。特别是,我们提出了一种方法,假设过程平稳性,它优于国家的最先进的和其他两种方法,即使是非平稳过程,能够作出预测。我们还描述了一种方法,能够预测一个运行的情况下,将采取的活动的完整序列。所有这些方法进行了广泛的评估两个真实的案例研究。

英文摘要:

The ability to know in advance the trend of running process instances, with respect to different features, such as the expected completion time, would allow business managers to timely counteract to undesired situations, in order to prevent losses. Therefore, the ability to accurately predict future features of running business process instances would be a very helpful aid when managing processes, especially under service level agreement constraints. However, making such accurate forecasts is not easy: many factors may influence the predicted features. Many approaches have been proposed to cope with this problem but all of them assume that the underling process is stationary. However, in real cases this assumption is not always true. In this work we present new methods for predicting the remaining time of running cases. In particular we propose a method, assuming process stationarity, which outperforms the state-of-the-art and two other methods which are able to make predictions even with non-stationary processes. We also describe an approach able to predict the full sequence of activities that a running case is going to take. All these methods are extensively evaluated on two real case studies.
