TOWARDS FORMAL AND DEDUCTION-BASED ANALYSIS OF BUSINESS MODELS FOR SOA PROCESSES

The paper concerns formal analysis and verification of business models expressed in BPMN as a visualization of SOA processes. This verification is based on deductive reasoning which is in a certain kind of opposition to the well-known approaches based on state exploration (model checking). Semantic tableaux arc proposed as a method of inference. Both the logical specification and the desired system properties are expressed in the smallest linear temporal logic. Automatic transformations of business models (expressed as workflow patterns) to temporal logic formulas are proposed. These formulas constitute a logical specification of the analyzed model. An algorithm for generation of a logical specification is presented.
