- Abstract:
Project scheduling is the practice of regulating and controlling the execution and performance of a construction project. The practice involves the establishing of a plan for the project execution based on engineering and administrative requirements, and available resources. Available computerized scheduling software had been criticized for its inflexibility, impartiality and inability to evaluate the schedule reliability. In the field of highway construction in the state of Florida, the utilization of computerized scheduling techniques in preparing and monitoring construction projects has been observed to be very limited. In addition to software inflexibility, the absence of an activity-oriented coding system for highway construction projects is among the reasons that pertain to the limited use of scheduling software. The vast anticipated growth in highway construction and maintenance projects, necessitate the utilization of a specialized domain-oriented computerized scheduling technique which will provide highway construction parties with schedule evaluation and activities execution regulations. This study is focused toward the development of a knowledge-based diagnostic model that will examine the data produced by a computerized scheduling technique about an initial or in-progress highway construction schedule. The model evaluation will be done in compliance with facts and regulations pertaining to scheduling highway construction projects. The facts employed in this model include scheduling techniques knowledge, general construction scheduling knowledge and highway construction regulations. The model knowledge base was developed using an expert system shell featuring the ability to interface dynamically with external data base files. Using an IF-THEN-ELSE production rules and a Standard Query Language program, the model prototype is designed to counsel the user with instructions and observed malfunctions regarding the schedule under evaluation. The results of the model prototype evaluation may be presented in a form of on-screen or printed reports.
