The combination of process modeling and simulation-based analysis provides a quantitative approach to analyze business processes, and to evaluate design alternatives before committing the required resources, to properly align operations with business strategies, improve operational efficiency, and gain competitive advantage. However, the use of simulation-based analysis is still limited in practice, mainly because it does not exploit process modeling standards and typically addresses performance-related properties only, such as time and cost. This article proposes a methodology that first extends the standard language for process modeling (i.e., BPMN) to introduce a flexible and accurate specification of business process resources, and then exploits the extended process specification to analyze and predict the process behavior by use of a simulation approach that takes into account reliability-related properties, to consider unexpected failures of process resources. The simulation-based analysis is implemented by use of a domain-specific process simulation language that preserves the BPMN execution semantics. An example application is introduced to show the importance of addressing both performance and reliability properties for the simulation-based analysis of business processes.

建模资源以模拟业务流程可靠性

流程建模和基于仿真的分析相结合提供了一种定量方法来分析业务流程，并在提交所需资源之前评估设计备选方案，以使运营与业务战略正确结合，提高运营效率并获得竞争优势。然而，基于仿真的分析在实践中的使用仍然受到限制，主要是因为它没有利用过程建模标准，并且通常只解决与性能相关的属性，例如时间和成本。本文提出了一种方法论，首先扩展了流程建模的标准语言（即BPMN），以引入灵活准确的业务流程资源规范，然后利用扩展的过程规范通过使用考虑可靠性相关属性的模拟方法来分析和预测过程行为，以考虑过程资源的意外故障。基于模拟的分析是通过使用保留 BPMN 执行语义的特定领域的流程模拟语言来实现的。介绍了一个示例应用程序，以说明在基于模拟的业务流程分析中解决性能和可靠性属性的重要性。
