Abstract

This paper discusses the random combined credit evaluation (RCCE) problem for the high-tech firm (HT-firm), and a mathematics frame of the RCCE is proposed: the several evaluation models in company with random time series are used to take combination evaluation to credit status of the high-tech firm (HT-firm). It showed us the concept of optimal weights of the RCCE. It also gave us the method to determine the optimal weights of the RCCE. At last, a necessary and sufficient condition of the optimal RCCE with the equal-weight was provided.

Keywords and phrases: random combined credit evaluation (RCCE), high-tech firm (HT-firm), optimal weight.
