Similar Petri Net models have been used in modelling workflow, the abstract relations and precedence requirements of tasks in a business environment [vdA98] Van der Aalst s workflow model is based on an enrichment of Petri Nets (transitions are augmented by the source of the firing impetus) and naturally does not discuss or define properties important to narratives per se. 3 Formalisms Our interest is in a simple formalism that can model normal ....

....of workflow specification was studied in several contexts. In [22] model checking was applied to Mentor workflow specifications. More specifically, their focus is on properties over graph structures (rather than execution results) A similar approach was taken using Petri net based structures in [29, 30]. In [8] Davulcu and et al. used concurrent transactional logic to model workflow systems, and verifying safety properties under certain environment was proved to be NP complete. Another technique for translating business processes in the process interchange format (PIF) to CCS was developed in ....

INTRODUCTION In the past few years, much research has been devoted to formal verification of business processes [14, 13, 11, 12, 10, 5].

....XRL workflows. 1. Introduction Recent years have seen the proliferation of workflow management systems developed for different types of workflows and based on different paradigms [9] Despite the abundance of such tools, the critical issue of workflow verification is virtually neglected [1]. Few tools provide any form of verification support. The tools Woflan [11] and Flowmake [10] are two noteworthy exceptions. To complicate matters, more and more workflow management systems are used to support interorganizational business processes, e.g. in the context of Business To Business ....
....definition before it becomes operational. In fact, for interorganizational workflows, the costs of putting an erroneous workflow process definition into production are enormous because of the efforts required to repair errors crossing organizational boundaries. The soundness property, defined in [1], relates to the dynamics of the workflow process definition expressed in terms of a so called workflow net. A workflow net is a Petri net with one unique source place (for the initial state) and one unique sink place (for the final state) A workflow net is sound if the following requirements are ....

Unfortunately the proofs are quite complex and require a lot of preliminaries. The paper builds on Petri nets [43, 44] sound WF nets [1], branching bisimilarity [25] projection inheritance [14] and GCD LCM of processes [6, 7] The corresponding concepts are all introduced in Section 2. Readers familiar with these concepts can pass over selected parts of this section. Section 3 introduces the framework used to model ....
