Computerized Approach for Matrix-Form FMEA

This paper discusses a computerized technique for preparing a matrix-form of failure modes and effects analysis which has previously been completed using manual methods. The basic input to the computer is a definition of each element of the system, applicable failure modes, and the resultant effect of each failure mode. From this input, the computer develops the matrix, locates the intersections on the matrix between elements of the system and effects, and formulates the text of the failure effects. The principal advantages in using the computer include lower cost, greater accuracy, faster preparation, overall consistency in the final effect statements, and elimination of many repetitious and tedious tasks.
