Important Approach

Theorem proving is an important approach in formal verification. Higher-order logic is a form of predicate logic that is distinguished from first-order logic by additional quantifiers and stronger semantics. Higher-order logic is more expressive. This paper presents the formalization of the linear space theory in HOL4. A set of properties is characterized in HOL4. This result is used to build the underpinnings for the application of higher-order logic in a wider spectrum of engineering applications.

Comprehensive Framework

In this chapter, the authors first provide the overall methodology for the theorem proving formal probabilistic analysis followed by a brief introduction to the HOL4 theorem prover. The main focus of this book is to provide a comprehensive framework for formal probabilistic analysis as an alternative to less accurate techniques like simulation and paper-and-pencil methods and to other less scalable techniques like probabilistic model checking. For this purpose, the HOL4 theorem prover, which is a widely used higher-order-logic theorem prover, is used. The main reasons for this choice include the availability of foundational probabilistic analysis formalizations in HOL4 along with a very comprehensive support for real and set theoretic reasoning.

Computationally Expensive

Reliability analysis of engineering systems has traditionally been done using computationally expensive computer simulations that cannot attain 100% accuracy due to their inherent limitations. The authors conduct a formal reliability analysis using higher-order-logic theorem proving, which is known to be sound, accurate, and exhaustive. For this purpose, they present the higher-order-logic formalization of independent multiple continuous random variables, their verified probabilistic properties, and generalized relations for commonly encountered reliability structures in engineering systems. To illustrate the usefulness of the approach, the authors present the formal reliability analysis of a single stage transmission of an automobile.
