Also, additive manufacturing, known colloquially as three-dimensional printing, is being used in limited contexts in the field and is a technology that promises to improve, and perhaps transform, maintenance. Retrograde comprises not only removing materiel from a theater at the conclusion of operations; it also entails the shipping of reparable parts back to depots for repair, in preparation for those parts to be placed back into the supply chain.

The ManTech Program has addressed needs in both advanced, depot-level process fabrication technologies and more efficient repair and maintenance procedures. Additive Manufacturing The need to repair, remanufacture, or reconfigure components for weapon systems represents a supply chain challenge for the defense industrial base.

From page 94... ...
Additive manufacturing technology is well suited for the repair of high-value components or the production of small lots of components, and it has the potential to address supply chain concerns associated with surge production and long-lead-time items. Thus, additive manufacturing has great potential for addressing the availability of parts and components for critical DoD assets.

The Rapid Equipping Force's Expeditionary Additive Manufacturing Laboratory is a solid foundation on which to introduce additive manufacturing capabilities into the Army's logistics enterprise, as appropriate. Recommendation 5-2.

Connecting CBM to the Supply Chain Internal platform-focused prognostic capability, which is the current focus for CBM, needs to be complemented with an understanding of the historical consumption patterns and usage trends associated with operational and environmental demand factors external to the platform. These differential effects of operational mission types (e.g., training, combat, stability operations, and humanitarian support)

Much of the uncertainty associated with external factors in operational demand forecasting will be significantly reduced by using MBF in this way. Then when the 8 For a theoretical perspective on Bayesian statistics, see McGee (1971)

The test case for connecting CBM to the supply chain is for an AH-64 nose gearbox (a depotlevel reparable, or DLR) and compares the current baseline (using empirical data for this specific DLR)

RETROGRADE The material in this section is drawn mainly from Transforming U.S. Army Logistics: A Strategic "Supply Chain" Approach for Inventory Management, by Greg Parlier, a committee member (Parlier, 2005)

From page 101... ...
Army Logistics Support Activity efforts focused on ways to capture reverse logistics information, measure total retrograde times for the various theaters, and estimate the value of reparables delayed in retrograde. However, until recently, there has been no focus on defining and quantifying both the potential reduction in aggregate DLR inventory requirements and the effects of reduced customer wait time on readiness that could be achieved by synchronizing retrograde flow and depot operations with the forward supply chain.

From page 102... ...
It should adopt a new paradigm of readiness-responsive retrograde as discussed above for the crucial closed-loop retrograde supply chain within the larger logistics enterprise. Improving Retrograde Efficiency Over the past two decades the Army Materiel Command has incorporated Lean and Six Sigma manufacturing concepts into depot management practices with measurable success in reducing process variances and rebuild times.
|
From page 103... ...
The potential for retrograde improvement using the Intelligent Collaborative Aging Aircraft Spare Parts Support project and the Visualization of Logistics Data project appears enormous. When used in conjunction with improved reverse logistics, these could pave the way toward a truly synchronized retrograde, enabling a responsive closed-loop supply chain with reduced requirement objectives and improved materiel availability and operational readiness.

The Marine Corps, traditionally an expeditionary force, has use of two aviation logistics support ships, owned and operated by the Navy, for aviation maintenance and repair support to the Marine Corps expeditionary forces. A regionally aligned force structure could be adopted for the supporting multipurpose aviation sustainment brigades (MASMC, the replacement for Aviation Classification Repair Activity Depots)

This ultimately requires innovation in supply chain design, implementation, and, especially, supply chain management. The topic of innovation is discussed thoroughly in the following chapter.
