A Multi-level Grey Evaluation Model for Harms of Computer Virus

摘要

Due to the variety and complexity of computer virus harm, there are few practical evaluation methods currently. The paper presents harms' definition and classification of the virus. Then representative first-level and second-level evaluation indexes are proposed. However, as these evaluation factors could hardly be assigned with definite values and the evaluation process is more suitable to be regarded as a grey process, the paper constructs a multi-level grey evaluation model for the harm of computer virus. Different from the traditional grey theory, the paper propose a new method to confirm the scores for evaluation experts. After the experts give the scores for each second-level indexes, the model can calculate the grey comprehensive evaluation matrix, and then obtains a reasonable harm evaluation result.
