Logic prototyping: approach and use cases

Abstract

In this article, we present an approach to prototyping complex systems and processes using classical predicate logic. The prototype is built by the interpreter based on a logical description of the properties and/or behavior of the designed system. The description contains the definitions of the prototype elements and the constraints that the correct prototype must satisfy. Definitions are used to build a prototype, and constraints are used to analyze it and check the required properties. Definitions are interpreted using direct logic inference, constraints are only checked on the resulting model. A wider class of formulas is used than in well-known logical languages. Computable logical and denotational semantics are defined for them. In the process of building a prototype, logical errors of uncertainty, redefinition of functions, and contradictions are diagnosed. We are given examples of prototype descriptions used for semantic program analysis, space training, transport system design.
