Modelling Resilience Sample Clauses

Modelling Resilience. Task T8.2 has included work on the resilience and consistency of business processes, using the SAP mini-pilot and pilot studies. We have considered two forms of inconsistency. The first, semantic inconsistency, is application- dependent. The second, which we term temporary inconsistency is intro- duced through an exceptional situation such as the cancellation of an order 2The detailed requirements documents for the case studies are largely confidential, but descriptions of the pilots are provided in public deliverables for the deployment workpack- ages [DEP09a, DEP10a, DEP10b, DEP10c]. and may be tolerated for a bounded time period. A pattern has been devel- oped for modelling eventual recovery of business processes from temporary inconsistency [BFRR10]. Derived from an existing Event-B pattern for mod- xxxxxx time [CMR07], our new pattern models the on-time and late arrival of messages and allows for application-specific compensation for late arrival, restoring the semantic consistency of the business process. We have designed an algorithmic translation from the Business Process Modelling Notation BPMN to Event-B [BW10]. This covers most of the commonly used BPMN features and is structurally faithful in the sense that a new machine is added to the Event-B refinement hierarchy for both the control flow and the data information of each partner in the BPMN model. This is also the case for sub-processes within a partner. A final refinement layer adds the inter-partner messages. This achieves a good level of automatic proof and localises the cause of failed proof obligations. A further feature of the work is that we model the possibility of multiple concurrent instances of the same process. One of the possible benefits of translation from BPMN to Event-B is that a developer may annotate a BPMN diagram with application-level con- sistency conditions which could then be translated into Event-B and proved within the model. This possibility has been explored [BW10], although much remains to be done to make the resulting proof obligations amenable to au- tomatic proof. An important challenge is fine-tuning the translation to generate appro- priate invariants to maximise the proportion of automatically discharged proof obligations. The challenge is increased if the designer is allowed to add application-level consistency conditions to a model. Work on this is on- going. We also face the challenge of presenting the BPMN developer with information from failed proof at...
