The corporate debts default is always the issue that investors have concerned. At the same time, the metered calculation of corporate default probability has been drawn the attention of economic scholars and financial rating organization. The KMV modal is currently one of the popular combination credit risk management modals in international. This paper makes use of fuzzy measures and fuzzy integral into the KMV modal, thus getting the fuzzy KMV modal. Applying fuzzy KMV modal to actual circumstance, we get fuzzy default probability and default rates-hypotaxis degree function diagram. Comparing the average default distance of each industry, we can discover the default characteristic of each industry and predict the default probability of an industry or a corporate. |
