Formal Throughput and Response Time Analysis of MARTE Models

UML Profile for MARTE is an extension of UML in the domain of real-time and embedded systems. In this paper, we present a method to evaluate throughput and response time of systems described in MARTE models. A MARTE model we consider includes a use case diagram, a deployment diagram and a set of activity diagrams. We transform a MARTE model into a network of timed automata in UPPAAL and use UPPAAL to find the possible best throughput and response time of a system, and the best solution in the worst cases for both of them. The two case studies demonstrate our support of decision makings for designers in analyzing models with different parameters, such as the number of concurrent activities and the number of resources. In the first case study, we analyze the throughput of a system deploying on multiprocessor platforms. The second analyzes the response time of an order processing system.
