System Dynamic Modelling of Construction Cycle

Abstract:

As the overall demand in the construction industry increases, the intensity and degree of complexity of projects increases, which contributes to a certain impact on the course of project management. Any construction project is characterized by the overall construction cycle, which includes several complex activities as well as the outcome of which depends on internal and external processes. Various studies have been conducted to system dynamic modelling approach of construction industry that helps to solve and understand causes of influencing factors. The application of system dynamics in project management is able to explain and represent the course of the construction cycle in the form of a model. However, these studies did not cover the full construction cycle framework from a project management perspective due to it complexity. This study overview five main construction cycle elements (groups of factors) such as project management, project planning, risk management, project performance and project productivity which are affected by the variable elements. By optimizing and simplifying the perception of the complex system, it is proposed to divide the variable elements into 5 groups and 14 subgroups. By conducting interviews with experts in the construction industry, the proposed groups were linked to the main processes of the construction cycle. Using the modelling program Vensim DN, a conceptual framework of system dynamics model was derived, including the effects of groups of variable elements. This study is able to provide a fundamental System dynamics model of the construction cycle for further studies, which will improve the possibilities from various aspects.
