From the perspective of information economics, asymmetric information leads to opportunistic behavior, which is the primary cause of loss and risk in the construction market. This research studies on the probability and impacts of asymmetric information phenomena systematically and focuses on information asymmetry among owners, contractors and supervisors. This is conducted by inviting construc...

background: planning, organizing, staffing, leading and monitoring are the basic functional component of management. in present article, we aim to define the project monitoring and evaluation in health research system (hrs) considering its success and challenges based on our national experience. methods: in this study based on the information of annual medical science universities evaluation du...

Aimed at coping with the complexity of construction engineering cost evaluation, the advantages of rough set theory, particle swarm algorithm and BP neural network are integrated to put forward a new model of construction engineering cost evaluation, namely, the model of construction engineering cost evaluation of optimized particle swarm and BP neural network on the basis of rough set theory. ...

This paper tries to analyze common bridge construction defects, classify them into appropriate groups, and redefine them as a precautionary measure and means to improve quality in bridge construction. For this purpose, data on bridge construction since January 2007 were obtained from the evaluation report of the Public Construction Committee (PCC) of Taiwan. Bridge construction defects were cla...

A small scale, high precision co-ordinate table was developed as part of a project to solve measurement problems originating from microtechnic. Construction with a single reference surface was selected and vacuum preloaded air bearing applied in order to enable smooth motion and eliminate stick slip. Laser interferometers were applied to measure both the displacement and the angular error. The ...
