  1. ABET AccreditationBoardfor EngineeringandTechnology SENIOR CAPSTON DESIGN PROJECT STATISTICS & RELIABILITY CRITERIA By Prof. Reda Abdulaal 1426 H - 2005 G

  2. Requirements to ABET EC 2000 • Statistical analysis should be performed • Design reliability should be assessed • In some cases, risk assessment may be performed

  3. Requirements to ABET EC 2000 Statistical Analysis

  4. Statistical Analysis What is Statistic? It is SCIENCE of DATA Pieces of information gathered by individuals and/or organizations to gain knowledge Set of methods for Collecting, Organizing, and Analyzing

  5. What is Statistic? It is SCIENCE of DATA Set of methods of Collecting, Organizing, and Analyzing pieces of informationto gain knowledge

  6. Types of DATA Discrete or Continuous Discrete DATA Qualitative Quantitative Ordinal Nominal Interval Ratio Can be recorded (cost, weight, etc.) Can be counted (people, trees, etc.) Can be assigned (ownership status: 1-owner, 2-rent) Can be arranged in order And difference between number has meaning: (IQ) Can be arranged in order (excellent, very good, good) As Interval but there is Definite zero point (no. of defects) Discrete: Data that contains only integers Continuous: Data that contains any value over a particular range

  7. WHY ? • Data may be difficult to obtain • Data may be expensive to collect DATA Pieces of informationgathered by individuals and/or organizations to gain knowledge Population Sample Set of all possible information that is interest Portion of the population from which information is gathered

  8. WHO ? WHY ? • Scientists • Chemists • Engineers • Decision makers • Economists • Every one wants to gain knowledge • Inform the public • Provide comparisons • Explain outcomes • Predict for future • Establish a relationship • Estimate unknown quantity

  9. SCIENCE Set of methods of Collecting, Organizing, and Analyzing

  10. Data COLLECTION Techniques & Tools • Using available information • Observing • Interviewing (face to face) • Administrating written questionnaires Data compilation forms Eyes and other senses, watch, microscope Tape recorder, checklist, questionnaire Open/Close questionnaire

  11. SCIENCE Set of methods of Collecting, Organizing, and Analyzing

  12. Data ORGANIZATION Techniques • Graphically Charts, graphs, … • Numerically Tables The type of organization depends on the type of analysis required

  13. Tabular vs. Graphical

  14. Tabular vs. Graphical

  15. SCIENCE Set of methods of Collecting, Organizing, and Analyzing

  16. Data ANALYSIS Once the data is organized, various quantities associated with the data can be computed. • Mean • Standard Deviation • Correlation • Moving average • Exponential Smoothing EXAMPLES

  17. What is Statistic? It is SCIENCE of DATA It is Set of methods of Collecting, Organizing, and Analyzing pieces of informationto gain knowledge

  18. Requirements to ABET EC 2000 Design Reliability

  19. Definitions • Reliability • How long will the system operate before failure? • Design Reliability • The level of reliability inherent in the system as designed or manufactured

  20. Design Reliability • Level of Reliability affects by: • Weakness in design • Flaws in materials • Defects from manufacturing process • Maintenance errors • Improper operation

  21. What is required? • Design requirements to minimize the human errors: • Safety instructions • Maintenance rules • Operation manual • Apply standards

  22. Requirements to ABET EC 2000 Risk Assessment

  23. Definitions • Risk Assessment • Formal and systematic analysis to identify and quantify probabilities and consequences for personnel, environment, production etc of all failures of equipment/installation/facility

  24. What is required? • Requirements to minimize the risk: • Recommendation report • Use available tags
