Human Resources Risk Element Transmission Model of Construction Project Based on System Dynamic

Abstract

Human resources risks lead to undermine project performance, however, due to complex and flexible characteristic of the human resources risks, the prediction and control of risks resulting from human resources is more difficult than other risk factors. In order to achieve effectively construction goal, based on the generalized project risk element transmission theory and system dynamics, a system dynamics model of human resources risk element transmission during construction projects was developed, which analyzed different influence results that human resources risks of different time and different level caused and dynamic transfer process of human resources risk elements. Firstly, the restoration process of human resources can significantly delay project duration after human resources risk occurrence. Secondly, in the run of project construction, asymmetric composition of human resources can create unsaturation of real workload, which caused inefficiency of human resources. Finally, during different time that human resources occur, different measures which employed either increase numbers of human resources to speed up construction or no increase human resources result in delay of project duration will seriously influence project cost. Moreover, the case study makes a more particular knowledge of human resources risk elements transmission to quantitative description of project duration and cost. This model can provide important information for risk managers and project managers addressing human resources risk.

“…Moreover, SD models can be integrated with DES (Alzraiee et al, 2015; Pena‐Mora et al, 2008; Sadabadi & Kama, 2014), critical chain project management (CCPM) (Lee & Miller, 2004), dynamic planning and control methodology (DPM) (Bianchi, 2016; Cosenz & Noto, 2015; Herrera et al, 2019), fuzzy logic‐based change (Motawa et al, 2007; Nasirzadeh et al, 2019) and ABM (Barbosa & Azevedo, 2018; Jo et al, 2015; Wu et al, 2019). SD models are based on risk element transmission theory (Cunbin et al, 2015), construction safety using system archetypes (Guo et al, 2015) and/or Brook's law adding manpower to the productivity, costs and project duration (Garcia‐Alvarez et al, 2016).…”

Risk Perception-Based Project Contingency Management Framework

“…SD has also been used to demonstrate that project control processes are affected by risk perception [37]. The decision of when and how to spend the contingency budget depends significantly on risk perception [17].…”

System Dynamic Theoretical Framework for Construction Management: A Case of Baltic States

“…Yungi et al (2015) module on the transfer of human resource risk elements of system dynamics during construction projects examines the impact of human resources on project size, cost and duration. According to Yungi et al (2015), the risk module includes different levels of workforce change scenarios within the project, mainly caused by schedule shifts. Preventive actions are simulated to reduce the degree of risk and stimulate optimal interactions between characteristic factors.…”
