The DMSMS(Diminishing Manufacturing Sources and Material Shortage) can occur in every weapon systems and especially, this phenomenon frequently occurs in electronic parts. But we have no DMSMS-related directives, guidelines, regulations and activities, so we have some difficulties in operating weapon systems. In this paper, we review the reality of DMSMS in our weapon systems and then suggest effective alternatives to reduce the risk of DMSMS for weapon systems.

DMSMS(Diminishing Manufacturing Sources and Material Shortage) of weapon systems is caused by required increase in system life cycle and reduction of military electronic parts market share. This problem causes serious problems about Combat readiness and Life-cycle cost. In this paper, we review the method for managing the DMSMS and then suggest effective alternatives to reduce the risk of DMSMS for weapon systems, such as systematic DMSMS management system and quantitative design refresh planning considering the DMSMS.

A flare from an Air Force fighter was abnormally dispensed during the landing. To determine the cause of the abnormal dispensing, fracture analysis, signal analysis and reproduction experiments based on physics of failures were performed. The primary cause of the failure was analyzed to be due to an intermittent fault of an internal circuit card in the AN/ALE-40 chaff/flare dispenser by a broken lid of a capacitor, and the root cause which had derived the primary cause was considered to be an improper handling during the domestic maintenance which were changed from the overseas maintenance due to the DMSMS problem. Therefore, the overall process of the maintenance capability development system was reviewed and alternative ways that considers maintenance error decision aid(MEDA) for system improvement were suggested to prevent further failures.

DMSMS (Diminishing Manufacturing Sources and Material Shortage) is increased by developing the scientific technique and downsizing the military part market. DMSMS affects the increase in total life cycle costs and serviceability. Therefore, advance control for parts is important to reduce the cost, and a database is needed to share information on the DMSMS. A task needs to be performed continuously by setting the major control item to management more efficiently. The purpose of this study was to deduce the major control item for the DMSMS management system. Thus, the pre-control item basis of the DAPA (Defense Acquisition Program Administration) Manual and the SD-22 Manual were first selected, and the results of the survey were analyzed by AHP (Analytic Hierarchy Process) method. Fifteen of the detailed items were stratified into three criteria (Impact, Probability, and cost of the DMSMS), and each weight for the items was calculated using a nine-point scale survey. The AHP survey was executed with 25 specialists in the DMSMS management field, and the score of consistency ratio over 0.1 was excluded. The model explained the results and suggested future directions for development.
