Notice of Retraction Study in evaluating armored vehicle engine operating condition based on AHP-gray relating analysis

In order to forecast the using life of armored vehicle engine synthetically, the index system of armored vehicle engine using influence factors is established and optimized by means of the relativity analysis method, while the weightiness values of the indexes are calculated. An AHP-gray relating analysis is proposed and applied to evaluate the operating condition of the armored vehicle engine, so that the engine operating condition correctional coefficient is calculated. And some conclusions are given.
