The Operating and Support Management Information System (OSMIS) is a major portion of the Department of Defense (DoD) Visibility and Management of Operating and Support Costs (VAMOSC) Program. OSMIS, managed by the U.S. Army Cost and Economic Analysis Center (USACEAC), is the U.S. Army's source of historical operating and support (O&S) cost information for more than 500 systems deployed in tactical units -- Active, Guard, and Reserve.

Department of Defense analysts have found historical O&S data to be useful in projecting O&S costs for future systems, developing O&S cost analyses, and preparing O&S estimates. The types of analyses and comparisons include the following:

• Operating and Support Cost Reduction Efforts,
• Total Ownership Cost (TOC),
• Component Cost Analyses (CCAs),
• Program Office Estimates (POEs),
• Cost Estimating Relationships (CERs),
• Cost and Operational Effectiveness Analyses (COEAs),
• Economic Analyses (EAs), and
• U.S. Army Materiel Command (AMC) Major Subordinate Commands (MSCs) weapon/materiel system O&S cost comparisons to new systems in the acquisition cycle.

OSMIS Relational Database

The OSMIS Relational Database presents annual Operating and Support (O&S) historical information for Army Materiel Systems (such as Army aircraft, tanks and combat vehicles, etc.) which includes costs for the following:

• Class III consumption (POL - Petroleum, Oils, and Lubricants) for operating combustion/turbine engines; however, solid fuels, coal, and related products are excluded,
• Class V consumption (training ammunition only), and
• Class IX consumption (repair parts and components, including kits, assemblies and subassemblies, reparables, and consumables) required for maintenance support of equipment designated for OSMIS tracking and depot/intermediate maintenance costs.

This database presents easily locatable reference data that may be extracted by:

• Work Breakdown Structure (WBS)
• MACOM
• Installation
• Division and UIC

The OSMIS Relational Database contains the following commodity group of weapon systems:

• Aviation Systems consisting of rotary and fixed wing aircraft,
• Combat Systems consisting of tanks and combat vehicles,
• Artillery/Missile Systems consisting of artillery weapons, artillery support vehicles, air defense artillery and missiles, surface-to-surface missiles, and detection systems,
• Tactical Systems consisting of wheeled vehicles,
• Engineer/Construction Systems consisting of engineer, construction, electrical power generation, and floating equipment,
• Communications/Electronics Systems consisting of radio receivers, teletypewriters and terminal sets, switches (voices and message), etc., and communications and data processing systems, radar sets, and terminals, etc.

Data sources used in these reports are from the U.S. Army Logistics Support Activity (LOGSA), AMC's MSCs, the Industrial Operations Command (IOC), ODCSOPS, and ODCSLOG.
