Abstract
Under the condition of sufficient resources, there are many factors affecting the realization of extremely short construction period of engineering construction projects. Based on literature review and questionnaire survey, this paper firstly selected 17 influencing factors from the five dimensions of design, management, technology, policy and environment. And the factor analytic hierarchy process model was established based on Grey-DEMATEL-ISM. The model introduced the improved grey system theory and combined decision-making trial and evaluation laboratory (DEMATEL) with interpretative structural modeling method (ISM). In addition, the model can not only identify the critical factors in the system, but also present the internal logical relationship between the influencing factors through the multi-level hierarchical structure diagram. Finally, through the analysis of the influencing factors of extremely short construction period under the sufficient resources, it defined that the key factor is the natural environment and second is the structure type. The methodology implemented in this paper helps decision makers and managers of construction projects to understand the interrelationship and degree of influence among factors affecting the duration under the condition of sufficient resources, to effectively grasp key factors, and to effectively achieve project success.
Highlights
Schedule management as an important element of project management, which has attracted the attention of scholars and project managers [1, 2]
Through the analysis of the influencing factors by Grey-decision-making trial and evaluation laboratory (DEMATEL)-interpretative structural modeling method (ISM) model, it was found that the impact of each constraint dimension on the extremely short construction period is mainly reflected in the complex relationship among the influencing factors
This paper innovatively proposes to study the schedule problem under the sufficient resources and investigates the limiting factors that affect the achievement of very short schedules
Summary
Schedule management as an important element of project management, which has attracted the attention of scholars and project managers [1, 2]. The most extensive and indepth study is the shortest construction period under resource constraints [3–5]. With the frequent occurrence of natural disasters and public health events around the world in recent years [6], emergency hospitals, temporary rescue sites and road restoration projects need every builder to make a rapid response to minimize the damage. These projects often have very high requirements for the construction period with little restrictions on resources.
