Final Presentation Personnel Accountability &Tracking System Walter Hackett | Abdi Hussein | Tool Jampathom George Mason University SYST 798 – Fall 2009
Agenda 2 • Background • Problem Statement • Project Definition • Stakeholder Analysis • Competitor Analysis • Tradeoff Analysis • Business Case • Technical Case • Conclusion
Introduction / Background 3 • Historically, activities involving high risk to life and health have needed oversight, accountability, and situational awareness. • Personnel accountability systems have been implemented, mainly as manually operated systems. • The need for situational awareness increases exponentially in crisis situations where much is at stake and time is critical. • Example: US Navy experiences over 50 man-overboard situations per year—sometimes realizing that a sailor is missing only when performing a scheduled roll call. • Many of the current accountability systems are manually operated which can be error-prone and time consuming.
Problem Statement 4 • Current solutions do not provide a robust, automated, and scalable system to perform personnel tracking and accounting. • PATS is a MIL-STD-810F compliant system targeted to meet the crucial need to protect the most valuable assets of any system: the personnel carrying out mission critical tasks in life threatening conditions.
Project Definition 7 • Scope • Federal, State, and Local governments as primary customers • Emergency Response Agencies • Military and Department of Homeland Security • Hazardous industries as potential customers • Mine safety, Merchant Marine, Demolitions, etc. • Other industries as potential customers • Nursing homes, Hospitals, Mental health facilities, etc. • Assumptions • GPS will remain available for non-military use • There are no legal issues that impede system development • PATS development is not influenced by political issues • Team Role: Lead Systems Integrator for product development
Competitor Analysis 12 • Four commercially available alternatives: • CISCOR Personnel Locating and Tracking System (C-PLTS) • CISCOR Man-Down Alarm System (C-MDAS) • Intelliflex Personnel Monitoring (I-PM) • Incident Command Technologies Personnel Accountability Recorder (ICT-PAR) CISCOR Personnel Locating and Tracking System:http://www.ciscor.com/sys/personnel_locating_and_tracking.htmlCISCOR Man-Down Alarm System:http://www.ciscor.com/sys/man_down_alarm_systems.htmlIntelliflex Personnel Monitoring : http://www.intelleflex.com/Solutions.PM.aspIncident Command Technologies Personnel Accountability Recorder :http://www.incidentcommandtech.com/
Tradeoff Analysis 14 • Various technologies were considered for PATS components: • Personnel Locator • Signal Posts • Command Center • Trades Performed by Key Functions: • Location Determination • Communications • Computer and Information Technology

Business Case 18 • Business Objective • Market Situation • Cost Model • Break Even Analysis • System Life Cycle Schedule • Technology Roadmap • Risk Analysis
Business Case 19 • Cost Model • Used Cost Xpert v3.3 • Embedded Systems (Simple) Project • Function Points: 207 • Scaling Factors based on Medium-Large Sized Gov Contractor • Labor Rates • Technical: $150.00 • Management: $150.00 • Non-Technical: $100.00 • Results: • Total Effort: 22.6 Person Months • Schedule: 7.1 Months • Final Development Cost: $633,040.27
Business Case • Break Even Analysis • Interest Rate: 10 % (Yahoo! Finance) • Sales: 20 Units / Year • Price: $50,000 per unit • Production Cost: $35,000 per unit 20
Technical Case FCC Regulations MIL Standard 810 Encryption Web Accessibility/Sect. 508 Real-Time Location and Enviro Data Personnel Info GPS Signals PATS Distress Alert Incident Statistics/Recording User Preferences Real-Time Accountability Info Command Center Personnel Locator Signal Post GPS Satellites
Technical Case – Architecture • ZigBee Mesh Network • IEEE 802.15.4 standard • Decentralized, self-forming, and self-healing network • Low power, low cost, and open global standard • 3 types of nodes • Coordinator: Command Center • Router: Signal Posts • End Device: Personnel Locators • Data can be sent across multiple paths • High Frequency: 2.4 GHz • Data Rate: 256 kbps Coordinator Router End Device
Technical Case – SysML 24 System Modeling Approach • Organize the model and identify reuse libraries • Capture requirements and assumptions • Model behavior • Model Structure • Capture implied inputs and outputs, and data follow • Identify structural components and their interconnections • Allocate behavior onto components and behavior flow onto interconnections
Technical Case – User Interface 31 • Command Center User Interface Development • Wireframe Sketcher selected as UI modeling tool • Models for: • Real-time tracking and accounting • Distress calls and triggers (manual and autonomous) • Reporting • Personnel • System diagnostics
Conclusion 35 • Summary • Systems Engineering Process • Stakeholder Analysis • Alternatives & Tradeoffs • Cost Modeling & Financials • System Modeling & DoDAF Architecture Views • System Requirements Specification • Future Development and Possibilities • Software / Hardware Engineering • Products available for handoff • System Requirements Specification • Technology Tradeoff Analysis • Stakeholder Analysis • Business / Economic / Market Analysis
