Temporal Management of WS-BPEL Processes

Abstract

Abstract. WS-BPEL is de-facto industry standard for business processes. One of its major shortcomings is lack of temporal management capabilities. WS-BPEL offers no possibility for definition, calculation and monitoring of temporal values such as activity duration and deadlines as well as checking the temporal conformance of processes. This paper tackles temporal management of WS-BPEL based on two different techniques: interval-based and probabilistic. This paper describes temporal management of cooperating WS-BPEL abstract and executable processes. We have implemented a temporal management prototype as a WS-BPEL extension.
