Modeling of Variation Orders in Cost and Time Using System Dynamics in Iraqi Construction Projects
The construction industry owner quite often issues variation orders, and they can cause the contractor's work to be disrupted, impact time and cost overruns. Rework and minor changes can be qualitatively predicted and estimated during the bidding process for the most significant projects. This research explains the meaning, application, and potential application of system dynamics in assessing the impacts of variation order on cost and time. The model boundary is defined, including Exogenous and Endogenous variables. The Casual loop diagram CLD is built to explain the system structure after determining the modeling parameters fully. Using Vensim software, a system dynamics model is created, verified, and validated before being used to quantify the impact of variation orders in project scope on cost and time. The research aims to use system dynamics to simulate variation orders in Iraqi construction projects' cost and time. There are a large number of variation orders that occurred in most construction projects in Iraq.
