Abstract

In Model-Driven Engineering developers create a model of the system. Typically, such a model is verified to be safe by using model checking. For this, the developers need to create Linear Temporal Logic (LTL) formulas. Determining these formulas and modeling the system in the first place is time consuming and error-prone. We propose to automatically create the LTL formulas based on a risk analysis that has to be done anyway. This reduces errors and the time needed to create the formulas. Furthermore, we use these formulas to automatically synthesize a behavior model of the analyzed system that is safe by construction. The presented approach is implemented in the open-source tool PASTA. A case study with a simplified Adaptive Cruise Control system shows the applicability of the Safe Behavior Model synthesis.
