The US Air Force (USAF) has evolved a policy for the acquisition of fighter jet engines (FJE). In the 1970s and 1980s that policy placed a premium on FJE performance primarily measured by the metric: thrust/engine weight. In the 1990s, the USAF policy changed from an emphasis on performance to reduced life-cycle cost with a premium on sustainment. This paper reports the results of a study of how the USAF and Corporation Alpha (Alpha) have adapted their processes, practices, and policies to design, develop, manufacture, test, and sustain a family of FJEs. Each member of the family of FJEs is sequentially linked relative to insertion of technology designed to reduce sustainment costs. In addition to the technology linkages, the development of the family of FJEs selected for this case study is also tracked relative to US Department of Defense and USAF policy and industry design, build, and maintain processes, methods, and tools. This paper discerns the complex, highly integrated manner that characterizes the interaction between (1) technology, (2) policy, and (3) manufacturing and sustainment tools to produce a family of FJEs with improving sustainment qualities and non-degrading performance. The metric Unscheduled Engine Removals (UER) per 1000 Effective Flight Hours (UER/1000EFH) is used to compare the sustainability of each member of the selected family of FJEs. Our results are based on data obtained through a series of field interviews of USAF and civilian government personnel and Alpha personnel. The US government extensive database containing UER information is the primary source of MRO trends for the FJEs of this study. Our analysis shows that the family of FJEs sustainability...

Improvement of Mission Capable Rate (MCR) depends on factors such as transportation & logistics, resource loading & scheduling, and Available Parts & materials (AP&M). As shown in Figure 1, AP&M is a function of forecasting accuracy, which in turn, depends on the software, data, and vendor reliability data. Thus, to improve MCR, it is necessary to develop a clear understanding of the process for determining parts & materials requirements. This clear understanding of how to determine right amount of AP&M also means LSI stakeholders will have better risk management, better inventory management, better contract negotiation relationship, more efficient use of human capital, smoother production management and better supply chain management. Under ideal conditions, the right types of materials and parts would be available in the right quantities, at the right place, at the right time, and at affordable cost in order for the government and industry air force sustainment system to provide the required services efficiently, flexibly, and responsively under varying demand conditions. However, materials and parts shortages have led to a number of critical systems to have an unusually long Awaiting Parts (AWP) status during normal maintenance...

Complex sustainment solutions are comprised of a product-service system (product/equipment and service processes) on which service provision is based. The product-service system may be developed using the familiar methods of system engineering, but service delivery is of a fundamentally different nature. Relationships are critical to effective service delivery and trust is the primary outcome. Trust is a social construct that is heavily laden with emotional content, quite different from the conceptual constructs of product and system engineering. Service cannot be inspected in the way that product can be. Service satisfaction resides in the mind of the customer; the delivery of fit-for-purpose, mission capable equipment is a necessary but not sufficient condition for satisfaction. This seminar will explore the features of service and service thinking in complex sustainment solutions. It argues that while service thinking is distinct from system thinking, they must be harmonised in the act of service delivery.; http://www.sapmea.asn.au/conventions/sete2010/; http://www1.eleceng.adelaide.edu.au/seminars/index.php?category=research&year=2010&speaker=wood

Outcome-base contracts that provide throughlife sustainment solutions for complex systems such as aeronautical product offer "value in use" to the customer. Service is an inherent feature of the sustainment solution where the ultimate objective is to support the client, not just the product. Service satisfaction resides in the mind of the customer and the delivery of fitfor- purpose goods is a necessary but not sufficient condition for satisfaction. The end state of service is an intangible mental concept and service satisfaction is heavily shaped by the context in which the service is received. That context includes the emotional state of mind, its perceptions and preferences, its memories and patterns of unattended automated processing, and its plans for the future. Service satisfaction requires the service provider to have a highly developed concept of the mind of the customer. The desired end state of service provision is trust, wherein the customer seeks repetition of the service.; http://www.icas.org/; L. A. Wood

Force sustainment requires an optimum supply of resources to maintain and project power in an area. With sustainment reaching ever farther from the origin of supplies, commanders find an increasing exposure of their logistic trains to risk. To mitigate the increased risk from hostile forces, the survivability of supply vehicles must be considered in force sustainment operations to accurately capture a true throughput projection. Development of an optimum throughput plan for littoral sustainment will reduce overall risk to supplies and maximize throughput to the war-fighter. The research conducted focused on maximizing throughput considering the size, quantity, and risk to the cargo vehicles traversing the littoral arena. The major risk component studied is comprised primarily of littoral mines, though this risk is comparable to many other survivability situations. Use of data collected from computer modeling programs are used to compute and maximize throughput.

MBA Professional Report; The purpose of this study is to outline and analyze the acquisition and sustainment process for the current U.S. Marine Corps RQ-11B Raven Digital Data Link small unmanned aerial system program. The current sustainment of the Marine Corps Raven evolved from the support employed for its predecessor analog variant in 2008, which was originally supported by Marine organic assets below depot-level maintenance requirements. The Ravens manufacturer, AeroVironment Inc., now stations a field service representative in theater and has been since around June 2011 under a contractor logistics support contract after the Marine Corps struggled to implement organic support and sustain its Ravens at the organizational and intermediate levels. This report serves as a case study for insights into the acquisition strategies for future unmanned systems. I explore the advantages and limitations of organic versus contractor support options in the form of monetary, organizational, and logistical resource allocation by analyzing the spectrum of solutions throughout the supply and maintenance constructs. The analysis covers both operational and sustainment perspectives through the lens of doctrine, organization, training, material...

MBA Professional Report; The operation and support phase of a major weapon system is one of the most costly phases in the life cycle of a program. During this phase, the key stakeholders must build a long-term sustainment strategy to make sure the program is affordable, and that the weapon system is reliable and maintainable. The ultimate objective in this effort is to ensure all support providers, either organic or contractor, have mission readiness, translated into warfighter capability, as their long-term overarching priority. To this end, the business community (financial management and contracting) must develop a strategy that complements and satisfies the warfighters objective(s). The purpose of this research project was to examine critical sustainment program characteristics from a business community perspective for applicability in future weapon system sustainment efforts. The characteristics were identified to fall within three broad categories: (1) Reporting Mechanisms (developing and controlling the requirement); (2) Financial Management Perspective (understanding the funding process); and Contracting Perspective (arranging for the requirement). Using the Sustainment Business Model, the research team conducted a comparative analysis of two programs: The F-16 Falcon and C-17 Globemaster. The research concluded with the identification of good practices and suggested recommendations.

This thesis examines how Naval Construction Forces (NCFs) Operating with Marine Air Ground Task Forces (MAGTFs) receive sustainment support. Restructuring of the military forces, in particular the Marine Corps engineer units, has resulted in an increase in the mission dependent general engineering support that the Seabees provide to MAGTFs. The Seabees have developed a robust initial sustainment capability that serves them well in independent operations, but that can be a significant liability when operating with MAGTFs. This thesis analyzes the impact this robust sustainment capability has on the Seabees when they deploy in support of MAGTFs in terms of mobility and footprint. The research shows that elimination of initial sustainment material from the Seabees can reduce the Aircraft Load (ACL) requirements for the our Navy Mobile Construction Battalions (NMCBs) notionally slated to Support a Marine Expeditionary Force (MEF) by more than 46 C-141B ACLs. Additional savings can be realized by realigning the medical capability of the NMCBs to a configuration similar to a comparable Marine Corps engineer unit. This reconfiguration would save weight and space as well as allow the NCF to eliminate almost $5 million in medical equipment from its NMCBs.

The Marine Corps has embraced the concepts of Operational Maneuver From The Sea (OMFTS) and Ship-to-Objective Maneuver (STOM) as the next progression in the evolution of amphibious warfare. These related concepts envision harnessing emerging technologies to allow the projection of naval power ashore faster and from greater distances than in the past. Additionally, both concepts identify the ability to conduct sea-based logistics (SBL) as a key requirement for successful implementation. Sea-based logistics involves executing a wide range of logistical functions from a sea-base rather than from sites traditionally established ashore. Acknowledged enhancements are required to realize a complete SBL capability; however, the ability to provide some measure of sea-based sustainment exists today. This thesis models the sea-based sustainment of Marine Expeditionary Unit (Special Operations Capable) (MEU(SOC)) forces deployed from Amphibious Ready Group (ARG) ships. Missions are developed for analysis; each is coupled with an appropriate force package of personnel and equipment density. Sustainment requirements and available transportation capacities are then determined and compared for each mission. This comparison along with several excursions provides insight into the nature of sea-based sustainment feasibility. It also gauges potential limitations for sea-based sustainment.

The Marine Corps has formed a vision of how to conduct future amphibious warfare through its development of Operational Maneuver From the Sea (OMFTS), Ship-to-Objective Maneuver (STOM), and Sea-based Logistics (SBL) concepts. These concepts have forces deploying directly from ship to objectives ashore with a reduction or elimination of logistics infrastructure ashore. Combat forces operating ashore will be sustained directly from a sea-base with support from ship-to-shore transporters. By sea basing logistics functions, there will be a much greater demand upon these transporters. This thesis models the sea-based sustainment of Marine Expeditionary Brigade (MEB) forces deployed from amphibious warfare ships. A scenario for analysis is developed with force packages of personnel and equipment located at certain locations ashore during different days of an operation. Sustainment requirements and available transporter capacity are then determined and compared for twenty-seven cases comprising different ship-to-shore distances, different levels of aircraft attrition due to enemy interdiction, and different footprints of mobile logistics forces deployed ashore. This comparison provides insight into the ability of SBL to sustain forces ashore conducting rations in accordance with OMFTS and STOM concepts.

Approved for public release; distribution is unlimited.; The Enterprise Information System (EIS) Value Assurance Framework (VAF) is an Information Technology (IT) governance model based on commercial best practice adapted to specific DoD and Intelligence Community (IC) acquisition policy requirements. VAF expands and abstracts traditional DoD “Availability” metrics such as “Operational Availability” Ao to develop objective time-based Key Performance Parameters (KPP) appropriate for software-intensive systems of systems. In particular VAF addresses both the DoD “Sustainment KPP” (S-KPP) and the “Net-Ready KPP” (NR-KPP). Hence, VAF provides an engineering assurance model for developing systems that deliver sustainable information superiority. In the VAF construct, the NR-KPP correlates measurable improvement in “Information Processing Efficiency” (IPE) to measurable improvement in traditional operational effect metrics such as Probability of Kill (Pk). In addition to that focus on operational efficiency, VAF recognizes that sustainment of modern IT systems requires process-level metrics that enforce speed-to-capability requirements. Hence VAF S-KPPs specify both threshold and objective speed-to-capability requirements commensurate with “Moore’s Law.” To achieve aggressive speed-to-capability...

Governmental organizations play a major role in disaster relief operations. Supply chains set up to respond to disasters differ dramatically in many dimensions that affect the cost of relief efforts. One factor that has been described recently is self-sustainment, which occurs when supplies consumed by intermediate stages of a supply chain must be provided via the chain itself because they are not locally available. This paper applies the concept of self-sustainment to response supply chains. A mathematical model of a self-sustaining response supply chain is developed. Analysis of this model yields insights about the relationships and interactions among self-sustainment, speed of disaster onset, dispersion of impact, and the cost of the relief efforts.

As the Department of Defense continues to face force and budget reductions, the Army must rise to the occasion and explore opportunities that will improve its level of wartime readiness within resource constraints. Senior Army leadership realized that one area needing substantial changes was the Army's maintenance procedures. This thesis examines the Army's Integrated Sustainment Maintenance (ISM) program. As with any program, there is a certain amount of managerial control necessary to implement and execute the program. The primary focus of this thesis is to identify what agencies, within the Army, are capable of providing the centralized management of ISM at the national level and what functions/responsibilities the National Sustainment Maintenance Manager (NSMM) should perform. ISM allows centralized management and decentralized execution of the Army's sustainment maintenance requirements through the consolidation of all sustainment maintenance activities under an integrated management structure. The goal of the concept is to maximize repair capabilities while providing high levels of operational availability for assigned weapon systems at a reduced cost. By balancing resource allocations, workload distributions, and decentralizing the execution of sustainment maintenance...

Approved for public release; distribution is unlimited; CHDS State/Local; Laying the foundation for the reestablishment of the Salt Lake City Fire Department’s intelligence program requires several steps: Establishing a need; identifying the stakeholders; developing an implementation and sustainment plan based on the key constructs of successful collaboration; and providing a continued mechanism for evaluation and adjustment. Distilling the constructs of collaboration into a key component of success will provide additional focus to the development and implementation process. The questions this thesis answers are, can trust be identified as a significant factor in successful, collaborative working relationships? And if so, how can focusing on developing trust add value and sustainment potential to the SLCFD intelligence gathering use and dissemination program? The research uses appreciative inquiry in combination with multiple case studies, examining elements of successful and unsuccessful collaborative efforts in the arena of the fire service and national security. This thesis investigates the rise and fall of the Salt Lake City Fire Department’s national security effort for the time period spanning pre-2002 Olympics to 2014. Components responsible for the diminished involvement since the Olympics are examined...

Approved for public release; distribution is unlimited; The Marine Corps plans to fight battles in the 21st century using the littoral battlespace to maneuver forces from a sea-base to the operational objective. Combat forces ashore will be sustained directly from a sea-base to allow combat elements to maneuver freely without having to defend a rear area. In this type of environment, planners must be able to convert current data, intelligence, and status reports of units ashore into useful planning information. A sea-based sustainment posture makes transportation assets in the ship-to-objective delivery network critical for sustainment. This thesis focuses on sustainment and distribution in a sea-based environment. The Sea-based Logistics Decision Support System (SBLDSS) is developed to assist sustainment planners in this environment to predict inventory levels of forces ashore and assist in managing transportation assets. First, typical forces are modeled to reflect both their composition and activities ashore. Resupply needs are determined based on the commander's concept of operations and logistics planning factors developed for each force. Transportation assets, used to sustain the forces, are modeled. Demand is then placed on these transporters by both logistical and operational missions. Finally...

MBA Professional Report; Secretary of Defense Donald Rumsfeld, in a memo dated 19 July 2001, indicated that one of his highest priorities in transforming the Department of Defense (DoD) is to have reliable, accurate and timely financial management information. To facilitate this, Secretary Rumsfeld established the Business Management Modernization Program (BMMP). The BMMP is an implementation program charged with transforming the DoD's framework. One of the initiatives of the BMMP is to provide a modern financial management system that transforms business operations to achieve improved warfighter support while enabling financial accountability. The tool, the Defense Enterprise Accounting Management System (DEAMS) is a modified Commercial Off the Shelf (COTS) financial management system. DEAMS is expected to transform DoD financial management so that timely and accurate information supports effective decision-making. According to DoD guidance, to effectively develop, acquire, test, and support DEAMS it is critical that system resources are identified, tracked and evaluated. Through out this document, this process will be referred to as a support/sustainment plan. To date, a viable system support/sustainment plan has not been developed for DEAMS. The focus of this MBA project is to create a platform for a support/sustainment plan. The support plan is a living management tool. Its purpose is to ensure the system performs to warfighters requirements and identifies system performance short-comings over its life cycle.; US Air Force (USAF) author.

Approved for public release; distribution unlimited.; Naval Expeditionary Forces (NEFs), including the Marine Air Ground Task Force (MAGTF), will play an increasingly important role in the U.S. National Military Strategy (NMS). Future NEF roles will be shaped by the demise of the Soviet Union, advances in weapons technologies, mounting fiscal and resource constraints, and the rise in requirements for U.S. involvement in regional crises. Designing the right MAGTF to respond across the spectrum of conflict requires a keen understanding of readiness and sustainment issues and their associated costs. This thesis calculates the tooth-to-tail ratios of MAGTFs and uses them as a measurement of a force's readiness and sustainment capabilities. This thesis considers the readiness and sustainment requirements for particular MAGTFs performing various roles as outlined in the current NMS. The force structures of current notional and future MAGTFs are performing various roles as outlined in the current NMS. The force structures of current notional and future MAGTFs are developed and analyzed and compared in terms of representative capital value and operating and support costs associated with raising and maintaining a specific MAGTF capability. The results provide one approach to designing an investment strategy for future MAGTFs in an era of constrained resources.; Major...

Includes supplemental material.; This technical report analyzed the Navy's proposed Riverine Force (RF) structure and capabilities for 2012. The Riverine Sustainment 2012 Team (RST) examined the cost and performance of systems of systems which increased RF sustainment in logistically barren environments. RF sustainment was decomposed into its functional areas of supply, repair, and force protection. The functional and physical architectures were developed in parallel and were used to construct an operational architecture for the RF. The RST used mathematical, agent-based and queuing models to analyze various supply, repair and force protection system alternatives. Extraction of modeling data revealed several key insights. Waterborne heavy lift connectors such as the LCU-2000 are vital in the re-supply of the RF when it is operating up river in a non-permissive environment. Airborne heavy lift connectors such as the MV-22 were ineffective and dominated by the waterborne variants in the same environment. Increase in manpower and facilities did appreciable add to the operational availability of the RF. Mean supply response time was the biggest factor effecting operational availability and should be kept below 24 hours to maintain operational availability rates above 80%. Current mortar defenses proposed by the RF are insufficient.; NA

CHDS State/Local; Since 9/11, the U.S. has developed policies to counter the terrorist threat. Integral to those policies is preparedness. Homeland Security Presidential Directive 8 states that preparedness will include, "capacity building prevention activities such as information gathering, detection, deterrence, and collaboration related to terrorist attacks." Despite the criticality of capacity building in relation to preparedness, the term is not defined. There has been no discussion on what capacity building means. The term is often equated to federal assistance or used interchangeably with capabilities and capability based planning. Capacity building strategies, however, are distinct and link into wider economic, political, and societal issues. Despite capacity building's criticality to preparedness and sustainment, various or ambiguous interpretations will translate to differences in strategic priorities. This thesis will examine the existing strategies to determine the linkage between capacity building, preparedness, sustainment, capability, capability based planning, and the envisioned end-state. It will also address sustainment issues and homeland security costs based on differing capacity building interpretations. The end product is a capacity building definition that captures the costs and variables with building and sustaining capabilities. This thesis will also demonstrate how capacity building measures serve as the foundational premise for a sound homeland security strategic plan.; Lieutenant Commander...
