Spare parts are the key ingredient of effective system support. There is no question that initial stocks account for a significant proportion of total life cycle costs. Moreover, intelligent management of stock replenishment is the single most powerful and flexible means of improving performance and reducing costs over the operating life of a system.

VMetric XL is the most accurate, easiest to use, least data-intensive, fastest, most adapatble and most cost-effective spares optimization tool available anywhere in the world.

VMetric XL provides the timely and authoritative answers demanded by government instrumentalities and industry alike. The VARI-METRIC algorithms, developed by Dr. Craig Sherbrooke, are the basis of every serious spares optimizing technique in the world today, but no competitor can match VMetric´s simplicity and ease of use.

VMetric-XL is a multi-echelon, multi-indenture stock optimising model. You can model problems including up to 3 echelons of support with hardware systems of unlimited size and unlimited indenture levels. You can also perform joint optimisation of multiple end-items deployed at any number of operating sites, each of which may be uniquely defined.

VMetric XL is a spares stockage optimization model that computes the least costly quantity and mix of spare parts under a variety of user-defined operating and support assumptions.


>>> Note: VMetric XL is the Original Spares Tool - developed and written by Dr. Craig Sherbrooke.




------------ part of the "Savings Report" ------------------------------

Joint STARS, under a PBL contract, reported a $57M decrease in inventory cost using VMetric on deployment kits compared to the official US Air Force model used by Air Combat Command

Avondale Alliance unexpectedly won a $1B windfall as high bidder on LPD 17 through the use of the first version of MAAP, which was singled out as the discriminator in the competition with Litton Ingals by both Navy and GAO (GAO = Government Accountability Office)

US Coast Guard USCG R&D Center study (Rodriguez) found that savings of $180M could be obtained from aircraft inventories by general adoption of VMetric (recommendation subsequently accepted and implemented)

A VMetric study for USAF Air Mobility Command (part of the C-5 Tiger Team) found that Ao for the C-5 could be increased from Ao = 56% to 70% at the same time that inventory investment was reduced from $194M to $57M – and cannibalization eliminated

Logistic Management Institute study for NAVICP Naval Inventory Control Point found potential savings of $211M by switching from CARES/ARROWS to VMetric on the provisioning of the FA-18-E/F

US Postal Service claims to have saved several billion dollars by heading off bad designs of public vending machines through early use of EDCAS in new acquisitions
