Integration of RESTfulBP with BDIM decision making

Software runtime adaptability is one of the desired quality attributes in modern business process systems. It helps satisfy a variety of users' needs and accommodate diverse business and technical changes, both in the running software and its operating environment. In this paper, we present and demonstrate the application of our adaptation middleware MiniMASC+MiniZinc to business processes designed and implemented using the REpresentational State Transfer (REST) architectural style. We extended MiniMASC+MiniZinc with new autonomic business-driven decision making algorithms to determine which process fragment to execute in a decision point of a RESTful business process. Our new decision making algorithms enable different adaptation decisions for different classes of consumer at runtime depending on business strategies, in a way that achieves maximum overall business value while satisfying all given constraints. We demonstrate the new decision making algorithms in a LIXI (Lending Industry XML Initiative)-compliant loan application process system that was implemented using the REST principles. © 2010 ACM.
