This research was intended to reduce the cost of the kitting process errors in the parts supply system particular in the internal logistics system. For this purpose, in the target population, first with regard to the initial conditions identified errors and accumulate the requirements data then the error diagram is drawn and the error model is depicted and error modeling is done then, by changing the approach from inspection to self-control , the indicators required for self-control system have been calculated and due to the change in the approach to self-control, its requirements have been provided and typically, the error diagram is plotted with the desired value and new modeling, error calculation in this research has introduced self-control method and training for all personnel for their participation in the check-and-error process as a result, the kitting process showed an error close to zero with self-control.
