چکیده

Existing approaches to risk management in construction procurement primarily dwell on strategies designed for commonly identifiable risk factors in typical project environments. Commonly identifiable risk factors would include too early or late material delivery a condition typically ameliorated by implementing a Just In Time (JIT) plan; inferior construction materials typically mitigated by employing trusted vendors; or ineffective contractors primarily avoided by the use of experienced contractors. The purpose of this paper is to present a coherent model for procurement risk management for construction and infrastructure development projects within the context of dynamic project environments complex, or chaotic. For the purpose of this study, a critical risk path activity is one in which a delay of activity completion not only leads to project delay, but does so in a manner that may be fatal to project or at best, far greater than the actual delay. The study incorporates observations and theory with practical application for improving initiatives by emergency infrastructure development response organizations such as FEMA (Federal Emergency Management Agency) and USACE (US Army Corps of Engineers) in the United States, the NEMA (National Emergency Management Agency) in Nigeria, or ANDMA (Afghanistan National Disaster Management Authority) etc. This study presents risk response plans aimed at improving the potential occurrence of positive risk aspects while reducing, or eliminating the same for negative risk occurrences. This study explored material, equipment, and skilled labor procurement strategies related to project risk management from the perspectives of scheduling, cost, and quality three factors often referred to as the triple project constraints. It identified gaps within specific national Chi Iromuanya Capella University, USA Kathleen M. Hargiss Capella University, USA Caroline Howard HC Consulting, USA

A MATHEMATICAL MODEL FOR SELECTING THE PROJECT RISK RESPONSES IN CONSTRUCTION PROJECTS

Risks are natural and inherent characteristics of major projects. Risks are usually considered independently in analysis of risk responses. However, most risks are dependent on each other and independent risks are rare in the real world. This paper proposes a model for proper risk response selection from the responses portfolio with the purpose of optimization of defined criteria for projects. ...
