Effectivencess evaluation of artillery based on grey target theory

Method of artillery effectiveness valuation was introduced. According to the theory of grey systems, the patterns of alternative schemes are formed with the fourteen performance indices, which reflect the artillery effectiveness best, and the standard mode of these index series is derived according to the grey target theory. The weighting of every indices was determined by Shannon information entropy, thereby the calculation formula of approaching degree was updated. The good or bad effectiveness of artillery effectiveness can be distinguished by solving the approaching degree of patterns for their standard ones and making the queue of approaching degrees in the light of their values. It is found from the evaluation of three artilleries of 122mm that the method gives the same conclusion as that from conventional method and. Therefore, the method is proved to be valid.
