一种基于工作流的软件可靠性评估方法

随着工作流系统在企业运营中担负越来越重要的角色，工作流可靠性研究的重要性也日渐增加。文中提出了一套完整的工作流系统可靠性评估方法，帮助企业检验工作流系统的可靠性。首先，文中对工作流系统的体系结构进行分析，其中重点分析了工作流系统的流程及活动模式，提出一个以流程为基础的工作流可靠性评估方法。文中采用基于马尔可夫链的流程可靠性算法，将活动中的可靠性数据整合，计算流程的可靠性数据。在此基础上，基于Additive模型，根据流程的使用率将多流程的可靠性信息进行整合，最后求出工作流系统的可靠性数据。根据该方法，设计并实现了工作流系统可靠性评估软件，并通过在。 NET工作流平台上的实验，验证了该方法的可靠性预测效果是令人满意的。

A Method of Workflow-based Software Reliability Assessment

As the workflow systems take an increasingly important role in business,the study of workflow reliability becomes more and more important. A method of process-based workflow software reliability assessment is presented to help enterprise for testing the reliabil-ity of workflow system. First of all,analyze workflow system architecture,which focuses on workflow processes and activities patterns. On this basis,a process-based workflow system reliability evaluation method is put forward using the Markov algorithm to calculate the pro-cessing reliability data by integrating the reliable data of activities. Then,based on the Additive model,integrate the reliability information of the multi-process and calculate the reliability of the entire workflow system. Based on this method,design and implement the workflow-based reliability evaluation software. Experimental results verify the effectiveness of this process-based reliability algorithm through . NET platform.
