5. Supportability Elements Reliability Maintainability / Logistic Support Analysis (LSA) Testability / ID / PHM Logistics Engineering Integrated Logistics Support

6. Problem / Objective Problem Too many / conflicting parameters to effectively influence weapon system and support system design Objective • Develop meaningful (relative to design) effectiveness / supportability figures of merit applicable to • weapon system & support system design influence • measurement of weapon system & support system effectiveness / supportability

7. Benefits Provide rational quantitative basis for design decisions relative to effectiveness / supportability • evaluate point designs • evaluate impact of design changes • evaluate design alternatives • trade studies • sensitivity analysis to identify drivers Figures of Merit which are • meaningful to the Customer • understandable by Management • relevant to the Designer

8. Approach Develop Effectiveness / Supportability Figures of Merit Develop Analysis / Measurement Capability Requirements Develop Analysis / Measurement Capabilities (Models) Automate & Integrate with CAE / CAD

9. Caution Supportability can be an all encompassing buzzword The “system” requirement is more than supportability A “system” is required to counter a threat therefore • a system is designed to counter the threat • not be supportable • supportable is just one element

14. System Operational Parameters Operational Effectiveness • Readiness or Availability • Mission Success Ownership Cost • Logistic Support Cost • Operating Cost

15. Availability (Operational Readiness) “The Probability that at any point in time the system is either operating satisfactorily or ready to be placed in operation on demand when used under stated conditions.”

16. Operational Availability (Ao) Ao includes the impact of logistics on availability • logistics elements included must be defined in advance

23. Materials Management • All management actions, procedures, and techniques used to determine requirements to acquire, catalog, receive, store, transfer, issue and dispose. • Includes provisioning for both initial support and replenishment supply support. • Includes the acquisition of logistics support for support and test equipment: • Raw Material • In-Process Material • Finished Products and Spare Parts

24. Support Equipment • All equipment (mobile or fixed) required to support the operation and maintenance of the system. • Includes associated multi-use end items, ground handling and maintenance equipment, tools, metrology and calibration equipment, test equipment, and automatic test equipment.

25. Technical Data • Scientific or technical information recorded in any form or related medium (such as manuals and drawings). • Computer programs and related software are not technical data; documentation of computer programs and related software are. • Excluded are financial data or other information related to contract administration.

26. Training and Training Support • the process, procedures, techniques, training devices, and equipment used to train personnel to operate and support the system. • Individual and crew training (both initial and continuation) • new equipment training • Logistics support planning for training equipment and training device acquisitions and installations

27. Facilities • Permanent, semi-permanent or temporary real property required to support the system, including: • conducting studies to define facilities or facility improvements • locations, space needs, utilities, environmental requirements, real estate requirements and equipment requirements.

28. Packaging, Handling, Storage and Transportation Resources, processes, procedures, design considerations and methods to ensure that all system, equipment, and support items are preserved, packaged, handled and transported properly, including: • environmental considerations • equipment preservation requirements for short and long term storage • transportability.

29. Design Interface Relationship of logistics related design parameters to readiness and support resource requirements. • expressed in operational terms rather than as inherent values • specifically relate to system readiness objectives and support costs of the system.

30. Physical Distribution • Storage / Warehousing • Inventory Maintenance • Materials / Product Packaging & Handling • Transportation • Materials / Product Scheduling

31. Some Other Elements of System Supportability Traffic and transportation Warehousing and storage Industrial packaging Materials handling Inventory control Order processing Customer service levels Demand forecasting Procurement Distribution communications Plant and warehouse locations Return goods handling

32. Some Other Elements of System Supportability Parts and service support Salvage and scrap disposal

33. Supportability in Product Development The primary thrust is two-fold - Influence product design to ensure reliability, usability, safety, etc system - Identify the resources to ensure supportability of the delivered product and customer support Supportability translates performance, user requirements and user experience into the operational, maintenance and support concepts

34. Supportability in Product Development - continued Logistics design criteria and guidelines are provided to design As the schedule progresses, maintenance and support requirements (scheduled and unscheduled) are determined Requirements for support equipment, spare parts, publications, training, facilities, personnel and skills are established

37. Benefits of Design For Supportability • System Characteristics • Inherent Reliability • Easily Operable and Maintainable • Support System Characteristics • Adequate Supply of Trained Personnel • Minimal / Low Cost Support Equipment • Capitalize Existing Facilities • Transportable Design • Achieves Goals in: • Availability • Cost Effectiveness • Life Cycle Cost (LCC) • Operating & Support (O&S) Cost

38. Conceptual Initial Final Supportability During Design Objective: Minimum Downtime Minimum LCC

39. Supportability During Conceptual Design • A system’s design establishes the basic requirement for support resources • Support is a design parameter • Support features must be included in the conceptual design

44. Objectives Supply Chain Analysis Analysis provides understanding of critical tradeoffs and alternatives in practical decision-making for a range of inter-related supply chain management issues: • Structure of the Supply Chain: • “Optimal" numbers • Location • based on considerations such as customer service requirements, leadtimes, operational costs, and capacities. • Supply Uncertainty: • Relationship with suppliers • Selection of suppliers • based on cost, flexibility in supply contracts, expected learning curves of suppliers, and agreements on cost and information sharing. • Operational Policies: • Inventory control policies • Information-sharing strategies.

45. Prognostic Health Management Analysis The purpose of Prognostic Health Management is to repair systems before they fail, while maximizing useful life consumption, and to have the necessary parts, tools and maintainers waiting nearby to resolve the correct problem as quickly and efficiently as possible.

46. Supportability – How do you do it? Objective: design for support • Consider each ILS functional element during design process to minimize support • Develop clearly stated design objectives Design for support • Discard at failure • Eliminating repair reduces support burden • Possible for small end items, not realistic for large weapon systems • Repair versus discard quantifiable in terms of cost of item versus cost of repair • Modular replacement • Designing for discard would naturally include designing for modularity and modular replacement • Optimize modules in terms of size, cost of components and functions
