论文摘要
业务流程模拟是一种通用技术，可以预测一个或多个变化对过程性能的影响。主流方法在这个领域的局限性遭受了各种局限性，有些是由于它们将资源视为将资源视为未分化的实体。这些方法假定池中的所有资源都具有相同的性能并共享相同的可用性日历。先前的研究已经承认了这些假设，而没有量化它们对模拟模型准确性的影响。本文在自动从事件日志中自动发现的模拟模型的上下文中解决了这一差距。本文提出了一种仿真方法和一种发现模拟模型的方法，其中每个资源都被视为单个实体，其性能和可用性日历。一项评估表明，与具有未分化资源的模型相比，具有差异化资源的仿真模型更紧密地复制了周期时间和工作节奏的分布。
Business process simulation is a versatile technique to predict the impact of one or more changes on the performance of a process. Mainstream approaches in this space suffer from various limitations, some stemming from the fact that they treat resources as undifferentiated entities grouped into resource pools. These approaches assume that all resources in a pool have the same performance and share the same availability calendars. Previous studies have acknowledged these assumptions, without quantifying their impact on simulation model accuracy. This paper addresses this gap in the context of simulation models automatically discovered from event logs. The paper proposes a simulation approach and a method for discovering simulation models, wherein each resource is treated as an individual entity, with its own performance and availability calendar. An evaluation shows that simulation models with differentiated resources more closely replicate the distributions of cycle times and the work rhythm in a process than models with undifferentiated resources.
