Risk Assessment for Construction Projects Contracting Based on Unascertained Sets

This paper utilizes unascertained sets to analyze general contracting risk of construction projects. Firstly, principal component method was used to process a number of listed general contracting risk indices. The representative indices from principal component analysis process substitute for the primary indexes. Thus subjective random problem in choosing indices can be avoided. Then, risk fact...

Bayesian-network-based safety risk assessment for steel construction projects.

There are four primary accident types at steel building construction (SC) projects: falls (tumbles), object falls, object collapse, and electrocution. Several systematic safety risk assessment approaches, such as fault tree analysis (FTA) and failure mode and effect criticality analysis (FMECA), have been used to evaluate safety risks at SC projects. However, these traditional methods ineffecti...

Toward a knowledge infrastructure for traits-based ecological risk assessment.

The trait approach has already indicated significant potential as a tool in understanding natural variation among species in sensitivity to contaminants in the process of ecological risk assessment. However, to realize its full potential, a defined nomenclature for traits is urgently required, and significant effort is required to populate databases of species-trait relationships. Recently, the...

A Model for Prioritizing the Risks Associated with Road Construction Projects Based on Generalized Secondary Goal

   This paper aims at providing a new model based on Data Envelopment Analysis (DEA) to prioritize project risks. It is clear that the large amounts of involved capitals, the long term of infrastructure projects’ implementation, and the project management problems in on-time completion of projects indicate the necessity of paying particular attention to this issue and conducting applied researc...
