Risk Analysis Of The Project Investment On The Building

The paper introduces the risk analysis and evaluation method of engineering investment based on fuzzy mathematics and a new way of calculating steelyard weight. The new way of calculating steelyard weight remedies the limit of the common way and reduces the time of calculating. The paper keeps the principle of synthesizing the way of the qualitative analysis and quantitative analysis . Synthesizing the new way of calculating steelyard weight and fuzzy comprehensive evluation model is efficacious and reasonable to the risk analysis and evaluation . On the stand of structuring structure model , the whole system is divided into the risk system and the benefit system , whereby it mades the multi-layer struckture of the risk factors more fitness. It mades the conception more defmitude and it mades the conclusion more scientific.The method of analysising and evaluating the risk has the speciality of madding the analysis more all-sided and madding the conclusion more definite. It make up the shortcoming and proffer the definite direction for the dicision maker.
