Abstract: Computer systems in the past were significantly bulky and energy demanding. Nowadays, the computer systems have been considerably improved. Their reduced weight, volume, increased processing ability and robustness have allowed them to be included in the battlefield. Their use have allowed the inclusion of more sophisticated processing techniques which are not necessarily constrained to an "on" or "off" state. Smart processing methods and in particular the fuzzy logic methodology has allowed human knowledge in the form of simple rules together with several intermediate states to produce a range of states. The concept of smart or intelligent systems can simplify significantly the commanders' decision making. This leads to faster response times from the commander and as a result could potentially increase survivability. This paper considers a smart tank concept in the battlefield. However, smart processing methods can be applied to a variety of battlefield systems. This paper outlines the basic principles of fuzzy processing systems as a complementary method of assisting the commanders' decision making in the battlefield. The outline is followed by suggestions of how to model a particular tank sprocket electric drive sub-system within a tank. The smart processing method is not limited to the above example but intended to stimulate further application of the suggested method to a number of systems which require intelligent decision making in the areas of power and control.
