One major advantage of the delay analysis system is the consistency introduced into decision-making processes. An interactive system that fully integrates the data-collection system of a project eliminates the requirement of handling the same data numerous times, which is important considering . the vast amount of data generated by scheduling and control systems. Another advantage of the delay analysis system is that it reduces the amount of time required to gather data for the dispute-resolution process upon completion of a construction project. The long process of apportioning equitable allocation of responsibility for delays would be reduced by the availability of computer data bases and the documentation provided by the delay-analysis program. Each time an activity is processed, the information is stored in a historical data base. The information can be retrieved either by date or activity code. The program helps document decision-making processes. and a traceable link between collected project data and decisions is formed. Using the delay analysis system also allows managers to review decisions made under similar circumstances, which helps them to make more-informed decisions. It also furnishes managers with the proper tools for providing clients. top man- agement, and construction personnel with accurate project-progress infor- mation. As the delay analysis system is further developed the gathering and dis- 242 J. Constr. Eng.

Each delay in a construction project generates experience and expertise in recognizing and rectifying mistakes.

INTRODUCTION The Construction Decision Support System for Delay Analysis [delay analysis system (DAS)] augments existing project-control software packages by adding the capability for determining possible causes for project delays and suggesting alternative courses of action to prevent further delays. The delay analysis system program integrates expert knowledge with existing control systems in order to streamline construction-delay analysis and de- cision-making processes. The purpose of the DAS system is to provide an auxiliary computer software program that processes information related to project delays (both current and historical). The delay analysis system computer software program simulates the pro- cess of delay determinations by comparing technical parameters and ac- cessing knowledge bases. Potential causes of delays are determined and the program generates suggestions for possible alternative courses of corrective actions to reduce delays. The delay analysis system is not merely another scheduling software. It provides information related to the causes of project delays that is not available in project-control software packages, and it is used to augment existing scheduling software packages. In addition to each element of a project being monitored by project- management personnel, adequate feedback must also be provided to allow the selection of corrective actions in order to reduce or eliminate delays. The DAS program does not neglect human factors and judgments (which are required as an essential part of the analysis process); therefore, the program does not make decisions, but merely presents information required by managers to make more effective decisions, and it bases this information on the expert knowledge contained in the data bases.
