National Center for Manufacturing Sciences News and Views from the World of Manufacturing
September 2012 Welcome to The CTMA Connector, a monthly newsletter designed to provide news and ideas about the Commercial Technologies for Maintenance Activities (CTMA) program. The CTMA program is a joint Department of Defense/National Center for Manufacturing Sciences (DoD/NCMS) effort promoting collaborative technology development between industry and the DoD maintenance and repair facilities. This newsletter highlights ongoing projects, serves as a forum for promoting new project ideas, and provides other news of interest to the program. Our goal is to stimulate your participation and solicit your input. Feel free to submit items for the newsletter as well as any suggestions to make it more useful. More information about the program can be found at http://ctma.ncms.org/.

Completed Project: Implementation of Predictive Modeling in Support of USMC Systems Command – Product Group Nine (PG 09)
As platforms age, failures occur and must be handled by the maintenance processes. These events drive requirements for repair parts, placing demand on the supply system. For example, if the fleet has a surge in operations, the number of failures, maintenance events, and required repair parts likewise increase. If these requirements are not met, scheduled operations may not be met.
Repairs and replacements at the operational and intermediate levels for most components are handled internally by the United States Marine Corps (USMC); a limited number of secondary repairable items (SECREPS) are identified and contracted logistics support (CLS) programs are put into place for repair and return of unserviceable SECREPS.
The Clockwork Solutions, Inc.’s Total Life Cycle Management Assessment Tool (TLCM-AT) simulation model takes all of these rules into consideration. TLCM-AT was used to run “what if” scenarios on maintenance, logistics, policies, removal of parts for repair; and spare consumption. Analyses help to ensure that the forecasted project returns an investment over time in terms of readiness and costs. More detail is provided in Section 2.1 and Appendix A.
The TLCM-AT baseline model served as a starting point for scenario development, and
is essentially a snapshot of the current composition, disposition and state of the fleet
(Section 2.2). This included the work breakdown structure and configuration of each individual Medium Tactical Vehicle Replacement (MTVR), any spare parts on-hand or soon to be delivered, the current age and mileage of each vehicle and component, and the current status (functional or deadlined) of each vehicle and component. The outcome of this analysis showed that armored MTVRs performed worse across all selected metrics than unarmored, most pronounced for vehicles in-theatre, and worsening over time.
In the future, further analysis can be applied to develop provisioning plans to minimize delay to repair or replace components. For example, follow-on analysis can answer the questions:
How can provisioning strategy improve availability of armored MTVRs?
What is the best balance of cost and logistics performance in provisioning to support armored MTVRs?
How can provisioning be applied to deliver more consistent logistics performance in the armored MTVR fleet?
Global Combat Support System-Marine Corps (GCSS-MC) requirements stemmed from supply difficulties experienced during Operation Iraqi Freedom. A faulty network led to front-line Warfighters being unable to update request information and order supplies, resulting in Marine supply erring on the side of safety and sending above and beyond front-line requirements, resulting in overage of front-line inventory.
GCSS-MC decreases MTVR maintenance customer wait time and the proportion of maintainers’ time spent on administrative tasks. Fewer administrative hours gives the GCSS-MC maintenance process more flexibility to cope with a surge in demand.
During work conducted by Clockwork Solutions, Inc. (CSI) to assist in the subset of sustainment block planning encompassing repair parts, a requirement to explore cases where Class IX block performance may be improved was demonstrated. The work also highlights issues with Marine Corps data correlation. Specifically, technical manuals do not match Item Applications (Item Apps) data. This hinders employment of modeling and simulation tools to provide insight into the multiple future possibilities the MPF, or any Marine Corps element, may face. It is likely the development of more models to analyze Class IX will reveal more areas to improve materiel availability (Ma) through better sparing strategies.
The USMC Systems Command, Product Group 09 (PG09), Operational Force Systems (OFS) requires the use of the predictive life cycle modeling of Marine Corps ground weapon systems, as well as professional modeling and consulting support, to support various life cycle and product support analyses. Through this project, models previously developed with the TLCM-AT, as well as new system models were applied to support predictive analysis for Marine Corps Systems Command, and other Marine Corps agencies that require the use of predictive modeling.
Comprehensive life cycle scenario analysis will help the Program Managers, Life Cycle Logisticians, and leaders at the Enterprise level more clearly articulate Table of Authorized Materiel Control Numbers (TAMCNs) specific supportability requirements as they relate to system performance over time, to include: cost, operational availability, materiel availability and reliability.
Predictive life cycle modeling of weapons systems results in predictive analysis/modeling that directly leads to:
Enhanced supportability requirements, increasing availability of parts to the Warfighter; and reducing delay and cost by ensuring materiel availability/reliability.
Determination that incentives for early delivery of parts have a greater impact than penalties for late delivery of parts.
Each MTVR being a “collection of Line Replaceable Units,” the Performance Based Logistics (PBL) contract’s optimization of materiel availability at affordable cost expands service and readiness for the Warfighter.
TLCM-AT model directly reflects the composition and disposition of the entire MTVR fleet, with its consideration of all vehicle characteristics, including date placed into service, operational use tempo, and known miles driven per year.
The primary benefits of implementing GCSS-MC include two thirds fewer required man-hours for maintainer’s administrative duties, and a 25% decrease in average Customer Wait Time (CWT) – a savings of almost 20 days:
Free hours from administrative duties afford the GCSS-MC Maintenance process more flexibility to absorb increases in demand while continuing acceptable service levels.
Additional benefits of GCSS-MC include increased efficiency measured by fewer averge MTVRs in maintenance at any random time.
Decreased shipping times and parts delay improve CWT but also increase maintainer utilization. GCSS-MC puts Maintenance in a better position for these changes by reducing manpower requirements from other administrative sources.
GCSS-MC provides web-based technology for Marines to access and update near real-time information from any location or time. GCSS-MC combines data from maintenance, supply, and finance into a single, secure system to improve logistics, support, and warfighting capabilities.
Low Ma was observed in packages using current Class IX sparing levels. Risk-based sparing packages can be increase Ma by as much as 50%. Savings are represented as spare platforms that need to be acquired to achieve an average of 95% Ma over the first 30 days with the current Class IX blocks (Table 1).
