More recently contracts have been investigated for the design of cyber physical systems 179 180. This paper introduces design contracts between control and em bedded software engineers for building cyber physical systems cps. In this dissertation we introduce a design methodology that addresses the complexity and heterogeneity of cyber physical systems by using assume guarantee contracts to formalize the design process and enable the realization of system architectures and control algorithms in a hierarchical and compositional way. We use a variant of signal temporal logic namely stochastic signal temporal logic ststl to specify system behaviors as well as contract assumptions and guarantees thus enabling automatic reasoning about requirements of.

Compositional design of cyber physical systems using contracts ph d. We develop an assume guarantee contract framework for the design of cyber physical systems modeled as closed loop control systems under probabilistic requirements. The main educational goal is to confront the student with realistic mixed critical smart cps systems using the railway domain and autonomous trains as a case study. The results show that for this class of systems education should transition from a 2d.
