| dc.description | Highway engineers encounter numerous problems during rigid pavement construction. Thus, deciding on appropriate controlling measures is a crucial task. Expected problems range from mildly disruptive to financially catastrophic. Generally, these problems affect construction quality as well as increase initial cost. Although experts can control and solve these problems by using their tacit knowledge, novice engineers cannot. Transfer of expertise from experts to novices is difficult in the construction domain. Therefore, a system which experts could use to share their experience with other engineers both during and after a project is necessary. Without such transfer of expertise and knowledge, novices may repeat mistakes that experts have already learned to avoid. Documentation, classification, and computerization of these problems, their causes, solutions, and preventive actions can be very helpful in controlling and preventing them. This study describes the development of an expert system that can be used by novice engineers to control the problems they encounter during rigid pavement construction. The system can also be used as an instructional tool for prospective highway engineers. In addition, the system can archive and organize raw knowledge from experts to be utilized by engineers who work in this field. Domain experts can use the system to share their experiences. In the highway construction industry, several expert systems have been developed for design, maintenance, and rehabilitation purposes. However, to the best of the author's knowledge, no such system has been developed for pavement construction. Therefore, the system developed in this study, Expert System to Control Construction Problems in Rigid Pavements (ES-CCPRP), is a novel concept. Prior to system development, the need for such a system was determined from a literature review and validated through a questionnaire survey. A literature review, interviews, and a questionnaire survey of domain experts were conducted to construct the knowledge base, which is the core of the system. The knowledge includes problems encountered in the domain, their causes, preventive actions, solutions, and their effects, which were presented in a classified format. The knowledge was presented in the form of rules and coded in software by using Visual Basic. ES-CCPRP was verified and validated by extensive testing methods. Unit and integrated testing were performed during coding to debug the code and to verify that every unit executes its function and that all units work together correctly and effectively. In addition, the system was verified by 5 computer professionals who gave the system a score of 4 on a 5-point Likert scale, which indicates that the system satisfies requirements. Two domain experts validated the knowledge base content. One expert agrees with the knowledge by 86%, whereas the other agrees by 93%. Furthermore, the system was tested by different users involved in highway engineering, including experts, novice engineers, teaching experts, and students. The mean values of the overall system evaluation by the four types of users based on the 5-point Likert scale were 4, 4.5, 3.5, and 3.7, respectively. The satisfaction of the experts is another system validation method, and user satisfaction proves the effectiveness of the system.,Ph.D | - |
