Abstract : With the widely use of software technique in everyday applications, the correctness of software becomes more and more important. Formal verification is an important method to improve the correctness of software. However, it mainly takes formal languages as its modeling languages, which are based on mathematical logic, automata or graph theory, hard for learning and domain description. That hinders the applications of formal verification in industry. This dissertation investigates the design and practice of domain modeling and verification language EDOLA, to possess all the features of the usability for domain description, reusability and automatic verification. It proposes a three-level design method with the domain knowledge level, the common module level and the verification support level. The main contributions are summarized as follows: 1. In the domain knowledge level, the extraction and representation methods of the domain knowledge on both job-shop scheduling and PLC control software are proposed. It defines domain-specific operators of the job-shop scheduling problem, timed Petri net, etc. for the job-shop scheduling description. It also defines the operators of the scan cycle pattern, the complete environment pattern and five kinds of verification requests for the PLC domain description. It presents the formal semantics of the defined domain-specific operators, for the further EDOLA definition and its automatic verification. 2. In the common module level, the method to define common operators is presented with real-time as an example for common knowledge. It proposes two kinds of basic time operators and four advanced ones, which help EDOLA to describe real-time features easily and make the reusability of EDOLA design among time-sensitive domains possible. 3. In the verification support level, it presents a properties-oriented abstraction strategy, which reduces the state space and exploring space during automatic verifi- cation. It then formulates the encoding rules from EDOLA to first-order logic, thus implements the verification of the models with infinite states, with the help of first-order logic automatic theorem provers. 4. A prototype of the PLC domain modeling and verification language: EDOLA-PLC are developed and its tools are implemented. The tools provide an EDOLA-PLC editor and a compiler with the functionalities like syntax checking, semantics checking and translation-based automatic verification. 5. A case study of the EDOLA-PLC language on a dock fire-fighting control system is presented. It indicates that EDOLA-PLC is easy to describe both the PLC domain knowledge and the properties to be verified; is easy to describe the common knowledge: real-time and can be verified automatically. The results show that the abstraction strategy adopted in the verification support level of EDOLA-PLC improves the efficiency of automatic verification.
