Abstract

We describe our experiences using Z3 for synthesizing and optimizing next generation plant configurations for a car manufacturing company (The views expressed in this writing are our own. They make no representation on behalf of others). Our approach leverages unique capabilities of Z3: a combination of specialized solvers for finite domain bit-vectors and uninterpreted functions, and a programmable extension that we call constraints as code. To optimize plant configurations using Z3, we identify useful formalisms from Satisfiability Modulo Theories solvers and integrate solving capabilities for the resulting non-trivial optimization problems.
