Development of a knowledge-based schedule planning system

Project scheduling systems are essential tools for helping inexperienced project managers plan and monitor projects and for helping experienced project professionals analyze and evaluate project progress. This article explains the development of a knowledge-based schedule planning system. In doing so, it first explores the literature on the need for more effective construction-project planning systems. It then details the three phases involved in developing a schedule planning system--phases that included modeling, prototyping, and testing-and describes the key aspects of each phase: modeling (work breakdown structure (WBS), job logic formalism, precedence conditions, redundant relationships), prototyping (database structure, heuristics, algorithmic procedures), and testing (evaluation process, test results in relation to quality and time productivity).
