Based On Fuzzy Influence Diagram Of BT Financing Affordable Housing Project Risk Evaluation Theory And Application

BT mode as a kind of attract social investment, solve the indemnificatory housingconstruction key bottleneck is the efficient way that capital needs, in recent years gottentatively used in the construction of affordable housing. Large BT financingaffordable housing project has a wide range, complex legal relations, influence factors,large quantity, long construction period and take up more money, buy back period long,financing structure is complex and there are many uncertain risk factors, etc. Wasinfluenced by these characteristics and the comprehensive factors, determines the risk ofBT financing affordable housing projects, which to a certain extent, affected theenthusiasm of social capital investment in affordable housing. In practice, therelationship between the risk factors of analysis, evaluation and management, is stillvery weak. How to systematically analyze the risk of BT financing affordable housingproject, evaluate and effectively control, maximum limit to reduce project risk, projectmanagement, and perfecting the affordable housing financing is of important theoreticalsignificance and practical value.Taking chongqing city as an example, the government-subsidized housing BTfinancing risk control and the problems existing in the management of the project,according to the characteristics of the BT project, after studying the affordable housingproject risk characteristics, on the basis of BT financing on the basis of the theory ofrisk analysis and control, of BT financing affordable housing project risk has carried onthe system research. First of all, the influence diagram method is adopted to BTfinancing affordable housing has carried on the comprehensive identification of riskfactors in the process of project implementation, established BT financing affordablehousing project risk and risk testing table space; Then, using the theory of fuzzyinfluence diagram, further study on the interaction relationship between each riskfactors, set up chongqing BT financing affordable housing project risk evaluation modelfor the fuzzy influence diagram; Second,"minxin garden" in chongqing public rentalhousing construction project as an example, the use of BT financing affordable housingin chongqing project risk evaluation model, fuzzy influence diagram of BT project isthe most sensitive repurchase risk question has carried on the detailed analysis and riskassessment, on this basis, according to the risk assessment results put forward thecorresponding "minxin garden" public housing project risk control strategy. Finally, the comprehensive risk analysis and evaluation, in front of the affordable housing inchongqing use of BT financing model risk control policy Suggestions are put forward.This paper is based on fuzzy influence diagram theory of affordable housing inchongqing BT financing risk evaluation model of project risk fuzzy influence diagram,and based on this, advances the affordable housing in chongqing of BT financingproject risk control policy recommendations, the BT financing affordable housingproject risk analysis and control is a new exploration, to improve and enrich the BTfinancing affordable housing project risk identification and evaluation theory, at thesame time to promote our country of BT financing affordable housing project riskeffective control and management of the engineering practice provides the reference.This paper combining with the chongqing social sciences planning project ofchongqing sustainable affordable housing construction of BT financing model and riskcontrol theory research "(Number:2011YBGL112) completed.
