Typically, workflow applications are constructed from basic functionalities that may be realized by alternative services deployed in heterogeneous runtime platforms. Depending on workflow structure and selection of services, the applications differ in attributes such as price, Quality of Service (QoS) and others. In the paper, we propose a method of evaluation of workflow runtime platforms using Data Envelopment Analysis. We present calculation rules and algorithms that enable conversion of workflow data to values applicable for DEA modeling, which concerns workflow structure, interoperability constraints of heterogeneous systems and QoS attributes. Then, we model runtime platforms as Decision Making Units that intend to optimize their performance in terms of the final price and QoS.
