  1. Human Systems Integration Railways Systems: Applications HSI beyond DoD Dr. Jen Narkevicius Jenius LLC

  2. Attention to Human Error • National Rail Safety Action Plan • Fatigue Risk Management Program • Close Calls Reporting System But . . . Not Addressing “Design Induced Error” in a Meaningful Way — Until Now.

  3. “Design-Induced Errors” • Human Errors that Occur as a Result of Interacting with Systems that Were Designed with Little Consideration for Human Abilities and Limitations. • Errors Produced as a Result of Lack of Utilization of Error Reducing Design Approaches (i.e. Redundancy, Feedback, Intuitiveness, Easy Recovery From Input Errors, etc.)

  4. Introducing Technology Safely • Safe Introduction of New Railroad Technologies • Upgrade of Existing Technologies Without Compromising Safety • Efficient Use of Technology (Promotes Rail Commerce)

  5. There is No Such Thing as an Unmanned System

  6. Technology Process • Lack of Standardization in How Technology is Introduced in the Railroad Industry. • Is There a Method or Process to Examine Possible Risks and Limitations of the Technology? • Product Safety Plan? How we introduce technology can directly affect human error and safety.

  7. What is HSI? "Human Systems Integration: interdisciplinary technical and management processes for integrating human considerations within and across all system elements; an essential enabler to systems engineering practice.” INCOSE • interdisciplinary • technical and management processes • integrating human considerations • essential enabler

  8. Hardware Software Where We Have Been…

  9. Manpower Personnel Training Retention QOS QOL System Safety Occupational Health Human Factors Scheduling Recruiting Habitability Environment Personnel Survivability HSI is the component of SE that focuses on Human • Human Factors* • Manpower • Personnel • Training • Survivability • Habitability • ESOH (Environment, Safety, Occupational Health) * HFE is the direct input to SE

  10. Simplified SE V System that services the initially stated user requirements User’s requirements to perform Requirements Implementation Specification Integration Details to meet user needs Working the components and subsystems together to achieve the need Design Potential solution incorporating users, hardware, software, and organizational structures

  11. ReduceLife Cycle Cost Total Life Cycle Cost Reduce Manpower Adjusted Total Life Cycle Cost with HSI Cost Avoidance Reduce Skill Levels Reduce Training Reduce Tasks COST Reduce Mishaps Minimal Performance Reduce Injuries Desired Performance Reduce Deaths HSI permits increased capability while reducing cost OPERATING CAPACITY Increased Operator Capability Match Manpower and Personnel to Tasks Optimize the Human Interface Maximize Availability HSI Impacts on Capability & Cost

  12. What You Don’t See… You Don’t See the Hidden Costs Related to Training, Manpower, or Error-Inducing Designs. Human Factors are Part of the System. Poor Integration of Humans Into Advanced Technology is Costly.

  13. Why the Interest/Expectations • Disciplined, Unified, and Interactive Approach • Incorporate Human Considerations into System Design • Domains are Interdependent and Addressed Together • Improve Total System Performance Not Just One Piece • Improve Operational Effectiveness and Suitability • Reduce Total Cost of Ownership • Incorporate Processes and Structures to Improve Performance by Improving Performance of all the Parts of the System

  14. Initial Design and Human Requirements Cab Technology Integration Lab • Simulation and Modeling Help Derive Human and System Requirements • Use Lab Tools Across HSI Elements for integrated solution Develop a Feasible Solution

  15. Deliver Systems that Meet Operational Requirements(not just tech requirements) Trade offs and Final Requirements Requirements Document Model Acceptable? Iterative Process Re-run Human Task Network Model Acceptable Final MPT Requirements Final Design Requirements Human Task Network

  16. CTIL Lab Components… Building an HSI/SE Lab

  17. HSI Returns • Leverages Research and Analysis to Optimize Investment Decision-Making to Yield Greater Return on Investment • Direct testing of requirements, design, and implementation • Improved Safety • Better Performance • Manpower Cost savings

  18. HSI Way Ahead • National Rail Safety Plan increasing safety and efficiency across the System • HSI in Product Safety Plans • Improved Manning of New and Existing Train Systems • HSI Brings the Human Factors/Element into the Mix for Rulemaking, Systems Operation, and Operational Work • Addresses Human Element in PTC, RCL, Close Call Reporting Systems (CCRS)
