Evaluation of Overland Mobility of Tank Based on the Theory of Grey Target

Based on the theory of grey target,the patterns of different schemes on the overland mobility of tank are formed with the principal tactical and technical performance indices,and then a standard pattern is constructed according to ideal or better performance values.Performance evaluation of the schemes is realized by calculating the approaching degree of each pattern to the standard one.It is evaluated that the overland mobility of tanks produced by different countries and during different periods with very simple algebraic operation.The conclusions obtained agree with the results verified by other evaluating methods and the actual using situation of tanks in battlefield.Therefore,the method is proved to be valid.
