TCO Simulation ToolPerformance Calculations
Most important: GSP calcualtions on complete work cycle needs to be correct (in terms of time (i.e vehicle speed) and fuel consumption.
– AH: measurements carried out, verification of system in progress. Good preliminary results
– WL: Incorporating Reno Fillas operator model in State Flow in GSP. Use measurements by Bobby Frank to verify system behaviour.
– EXC: Pending. Waiting for first model in GSP.
