Diagnostic System for Preparing Decision Tree Model to Identify the Changes in Specific Time of Project

الملخص

Time and schedule management is absolutely essential for project success. Running out of time, like running out of money lead to fail the project management. In construction project, a change refers to a modification to conditions, assumptions or requirements. It can be caused by either direct or indirect factors. Different changes may have different effects or consequences. This research aims to identify the major elements of changing the specific time of project, and this research also aims to build model tree to identify the causes which lead to change the time of project. The researcher presents decision making tool by using diagnostic system developed by using (VANGUARD SOFTWARE SYSEM) to enable engineers giving an appropriate decision by using decision tree model. The vanguard system is specifically designed to perform a wide range of tasks required in business decision analysis. Vanguard combines decision _making technology with methods to create diagnostic system applications.
