NEW RELIABILITY MODEL VARYING THE DORMANCY FACTOR

THE PURPOSE OF THIS PROJECT IS TO DEVELOP A USER-FRIENDLY, MICROCOMPUTER-BASED RELIABILITY/LOGISTIC MODEL FOR UTILIZATION IN DETERMINING POTENTIAL SPARE PARTS REQUIREMENTS, CONSIDERING THE DORMANCY FACTOR. OUR APPROACH WILL PRODUCE A SINGLE AVERAGE TIME-TO-FAILURE STATISTIC FOR EACH PART ANALYZED BY THE MODEL. THE STATISTIC WILL REPRESENT AN AVERAGE OF THE TOTAL POPULATION OF EACH PART AND CAN BE USED AS A SURROGATE MTBF STATISTIC IN OTHER MODELS USED FOR RELIABILITY OR LOGISTICS. OUR MODEL WILL DYNAMICALLY APPLY BOTH DORMANCY AND OPERATING LIGE ENVIRONMENTAL DATA TO COMPUTE AVERAGE TIME-TO-FAILURE. A SOFTWARE PROTOTYPE FOCUSING ON MICROELECTRONIC COMPONENTS WILL BE DEVELOPED FOR DEMONSTRATION IN PHASE I. POPULATING THE MODEL WITH ACTUAL PART DATA, UPGRADING THE MODEL TO ACCOMODATE RECOMMENDATIONS FROM THE PHASE I MODEL, AND DEMONSTRATING THE OPERATIONAL MODEL TO NECESSARY AIR FORCE PERSONNEL WILL BE ACTIONS DURING PHASE II.
