  1. An Approach to Examining Technical Alternatives James H. King Naval Architect/Signatures Thrust Leader Office of Naval Research 29 April 2004

  2. The Bait • Systems engineering provides a method for examining alternatives. Mr. King will discuss the application of technological forecasting, engineering, ship design, cost analysis, and operations research analysis to examine alternative approaches to solving naval problems. We will show examples of integrated analysis.

  3. The Switch • Systems engineering provides a method for examining alternatives. Mr. King will discuss the fundamentals of systems engineering and the implications for technology and application of technological forecasting, engineering, ship design, cost analysis, and operations research analysis to examine alternative approaches to solving naval problems. He will show an example of integrated analysis. He will present current challenges.

  4. Outline • The Principles of Systems Engineering • Implications for Technology • The Dimensions of Technology Selection • Some Methods of Technology Selection • Cost-Benefit Analysis • The Role of Probability • Risk • Current Challenges

  5. PRINCIPLES OF SYSTEMS ENGINEERING • THE FUNDAMENTAL PRINCIPLE OF SYSTEMS ENGINEERING Maximize the Expected Value • THE PRINCIPLE OF EVENTS OF LOW PRIORITY The fundamental missions of the system should not be jeopardized, nor its fundamental objectives significantly compromised, in order to accommodate events of low probability. Systems Engineering Handbook Robert E. Machol McGraw-Hill

  6. Principles (Cont’d) • THE PRINCIPLE OF CENTRALIZATION Centralization of authority and decision-making, that is, the centralization of information as distinguished from material. • THE PRINCIPLE OF SUBOPTIMIZATION The optimization of each subsystem independently will not, in general, lead to a system optimum and, more strongly, improvement of a particular subsystem may actually worsen the overall system.

  7. Some Methods of Technology Selection

  8. Why is Technology A Concern • Cannot afford everything • Not everything in basic research can be applied • Not everything can be implemented • Choices • A Systems Engineering problem • Cannot view each thing independently So, how do we decide?

  9. The Big Lie If you say something often enough, and with enough enthusiasm, it becomes fact

  10. New York Floor In the New York state legislature, who gets the floor?

  11. New York Floor In the New York state legislator, who gets the floor? The one who yells the loudest.

  12. Friends in High Places

  13. Goal Objectives Sub-Objectives Alternatives Analytical Hierarchy Process

  14. Variants • Pareto Analysis • Pain Analysis • Pair wise Comparisons • etc

  15. Strengths • Organized • Transparent • Repeatable • Sensitivity Analysis What Is the Key Weakness?

  16. Opinion

  17. Another Approach:Cost-Benefit Analysis

  18. Design, Cost, and Effectiveness ImpactsofSurface CombatantTopside Signature ReductioninLittoral Environments JAMES H. KING, Naval Architect Head, Signature Control Technology Department and DANIEL J. PLATT, Naval Architect Systems Assessment & Engineering Department Naval Surface Warfare Center, Carderock Division 1

  19. Purpose • Traditionally, goals based on threat weapon performance • Go beyond: • Impact of signature control on combat system • Impact of signature control measures on ship design • Cost drivers • Evaluate signature control in littoral warfare

  20. Process Baseline Ship Signature Control Methods Scenarios Signature Performance Prediction FORMULATION Threats Combat System Alternatives Ship Variants Specific Ship Impacts Operational Effectiveness Analysis COMPUTATION Concept Development Cost Analysis Cost- Effectiveness Analysis Goals DETERMINATION R&D Needs

  22. Candidate Ships A0, A1, A2, B2 B3 C0, C1, C2 C3, D3 C4, D4

  23. Mission Analysis Forward Presence HVU Protection TBMD NSFS AAW Picket NEO Spec Ops

  27. Conclusions • Study conclusions • The combination of signature control and appropriate combat systems yields cost-effective ship options • Increased cost of signature control is easily outweighed by decreased combat system cost • For some missions, signature control is vital to success • Future focus will be on the technologies appropriate to signature level 3 • Process conclusions • Small team, focused on limited missions and scenarios • Effective model for future studies

  28. What are the Weaknesses of This Approach?

  30. Hybrid Approach • Use AHP, or a similar approach, to identify and weigh objectives • Use rigorous cost-benefit analysis to evaluate alternative technology systems for achieving the objectives. • Evaluate the alternative systems using AHP • Guide investment decisions.

  31. What is the Fundamental Principle of Systems Engineering?

  32. What is the Fundamental Principle of Systems Engineering?Maximize the Expected Value What is Implied?

  33. The Role of Probability • Remember, Maximize the Expected Value • Performance • Cost • Weight • Risk • Etc • Expected value implies probabilistic assessment. • Results are rarely expressed this way

  34. The Two Sides to Risk

  35. Risk Management Assessment Event Probability Low Medium High Event Consequence Low Medium High Risk The Risk of Action

  36. Risk • But what about The Risk of Inaction? • Adversary development • Program delay • Increased cost • Technology abandonment • Etc. This should be considered!

  37. Technology Riskvs Potential D Size of Circle Indicates Technology Readiness Level A Cost C Which would you choose? B Benefit

  38. The Challenge

  39. Current Challenges • What is desired? • A fact-based technology evaluation system • Recognize uncertainty • Identify uncertainty • Balance risk of action and risk of inaction • Effective and efficient cost analysis • Suited to the immaturity and uncertainty of technology

  40. Current Challenges • Technology Solutions • Systems-based • Alternate technical system approaches • Use mixes of technologies that makes sense • Maximize expected value • Catch the revolutionary technology • Institutionalize systems engineering approach to technology selection

  41. A Identify Functional Needs Technology Cloud A Fact-Based Analysis A A Cost Performance Risk Probabilistic + - Maximized Expected Value
