Supportability DoD Definition

• The degree to which system design characteristics
  and planned logistic resources, including
  manpower, meet system peacetime operational and
  wartime utilization requirements

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

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

  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.

  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

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
