Embodiment 1

[0031] The history is organized as a list of sessions, each session is a finite collection of events or actions, and each event is represented by a predicate. Variable composition is interpreted as multi-ordered function symbols. Function symbols without parameters are called constants, which are represented by a, b, c, and d, and term variables are represented by x, y, and z, which can represent integers, strings, etc. Use prop to represent the set of propositional logic; use f, g, h to represent the function symbols of one or more parameters; use R to represent some relational operators, such as , etc., the specific expressions are as follows:

[0032]

[0033] where X -1 Indicates the "before" operator and S indicates the "since" operator. quantification formula

[0034] p stands for tau 1 ×...×τ n → n-ary predicates of type prop each x i is τ i type. The purpose of this quantification is to explain that the predicate p defines a subtype τ 1 ×...×τ n , which ...

Abstract

The invention provides a modeling verifying method for historical affaires, and belongs to the field of computer. A novel logic based on a linear time sequence logic is established, by expansion on the linear time sequence logic, things and time under the historical conditions can be described, and the described historical affaires can be verified. The limitation that the previous liner time sequence logic only can show future conditions is solved, language expression ability is improved, and the modeling verifying method for historical affairs has quite important role in improvement of software quality, ensuring of software correctness and the like, and has good social benefit.

Description

technical field [0001] The invention relates to a method for modeling and verifying historical transactions, belonging to the technical field of the Internet of Things. Background technique [0002] As the scale of software becomes larger and larger, the functions of the system become more and more complex, and examples of huge losses caused by small errors in the system become more and more common, and the efficiency and reliability of manual verification cannot be guaranteed, which makes manual verification The limitations of software are becoming more and more prominent. Therefore, how to ensure the correctness and reliability of software is becoming more and more urgent. Model checking has been widely concerned due to its many advantages such as high degree of automation. [0003] Model checking is an automated, model-based, property verification process intended for concurrent reactive systems. The purpose of its research is to expand the application field of automat...
