Trimming is a systematic tool which make any system model or process simpler. The purpose of using this tool is as follows:1)System model complexity reduction; 2)System model cost reduction; 3)System model improvement and development; 4)Patent-around design. There are three formal rules. A function maybe trimmed if: 1). An object of the Function does not exist; 2) An object of the Function performs the function itself; 3) Another Engineering System Component performs the useful function of the Function Carrier.
