Abstract:
Change management is an important aspect in construction project management, as changes constitute the main cause of schedule delay, cost overrun and other distributions. Many change management systems has been developed to minimize the impacts of change or facilitate changes management. However, change should be predicted as early as possible, and the problems can be identified and beneficial modification can be made as soon as possible. In this paper, an change prediction system using activity-based Dependency Structure Matrix (DSM) was developed to facilitate managing change, which can identify the possible changes in construction project. The outputs of the system for an application have represented the main function of the system. Methods about how to acquire date required for proposed system are also presented. The proposed system can be helpful for project managers to manage change more efficiently.

Introduction
Changes are very common issues in construction project especially in construct process. Any additions, deletions, or other revision to project goals and scope are considered to be changes, whether they increase or decrease the project cost or schedule [4]. In a complex construct process, the cause for change is more complicate. Most commonly, lack of timely and effective communication, lack of integration, uncertainty, a changing environment, and increasing project complexity are the drivers of project change [17]. Because of the cause’s complexity, the management of change in construct process is very difficult. However, changes have obvious impacts on construct process, not only on project’s schedule and cost but also on project’s performance, such as labor efficiency [1]. Furthermore, change is inevitable in construction project sometimes, primarily because of the uniqueness of each project and the limited resources of time and money that can be spent on planning, executing, and delivering the project [2]. Therefore, project management teams must have the ability to respond to change effectively in order to minimize the impact to the project.

The most effective method to take change in control is to design efficient change management system in project management system. Some of them have been the component of IT system. IT based methodologies such as computer aided engineering, engineering document management system are used to facilitate managing changes. C. Soh et al proposed a parametric technique based constraint methodology to coordinate design consistency to facilitate managing changes [5]. Furthermore, a reporting system was used to view the history of all changes made by all disciplines. C. Charoenngam had developed a Web-based change order management system that supports documentation practice, communication and integration between different team members in the change order workflow [6]. Analyzing the impact of changes or change orders also have been the mainly function of change management system. Dynamic Planning and Control Method (DPM) had been introduced to simulate the impacts of changes and other conflicts on construction project’s performance to facilitate management of changes [14]. However, these methods are mainly focus on how to minimize the change’s or change order’s impacts and how to facilitate the management process for changes. Kartam has suggested that conflict will be minimized when a problem has been studied as early as possible, since the problems can be identified and beneficial changes can be made [10]. Thus, change prediction theory had been introduced to facilitate managing changes in construction project. I.A. Motawa proposed a fuzzy logic based dynamic planning system for construction project and then the risk of change in the form of “project’s stability” can be generated by the system [9]. However, project lever change prediction is not enough for pre-management of changes, detailed information such as change probability and change scope is needed. In this paper, the causes of change in construction project are analyzed in the form of information flow, by using a matrix based methodology. And then, an
