DepotSim

DepotSim is a web-based DRC business intelligence solution with a simulation model at its core. DepotSim utilizes aircraft scheduling data and depot constraints such as facility capacities in order to project the future flow of aircraft through depots. Aircraft scheduling data can be automatically imported from existing depot scheduling systems or, alternatively, aircraft schedulers can utilize DepotSim to input aircraft schedules and produce elaborate schedules and reports. DepotSim simulates aircraft movement through the entire overhaul process using scheduled turn-around-times (TAT) for each process, actual/anticipated gains and delays, and projected facility shut downs. Aircraft movement is displayed graphically by day with particular emphasis on bottlenecks and delays. Additionally, Gantt charts of the schedule for each facility (hangar) can be created and displayed instantly.

DepotSim gives management the ability to conduct realistic what-if analysis to determine the correct courses of action, and the ability to test the success of previous decisions. Examples include the following:

"What would be the effect on TAT if we increased inductions by 20%?"
"If we worked Saturdays to reduce Metals phase by a week, would those aircraft be sold a week earlier?"
"If we took the two-year historical average TAT and applied those averages to In-Work aircraft, how would the results differ from standard TAT?"
"If we performed Assembly in building 82, how would that affect TAT?"
"If PDM aircraft need a new Integrated Systems Test phase, what will be the affect on throughput?"
"What would be the effect of a two-month shutdown for one De-Paint bay?"
"What if the new facility does not come on line until January?"

Specific implementations of DepotSim include:

Simulation Modeling Analytical Support System (SMASS) for Fleet Readiness Center Southeast (formerly NADEP Jacksonville). SMASS has recently been selected as a NAVAIR corporate tool applicable to all Fleet Readiness Centers. Aircraft schedulers at Jacksonville utilize the full DepotSim scheduling capabilities of DepotSim to perform aircraft level scheduling.
Maintenance Operations Support (MOS), implemented at Warner Robins Air Logistic Center (WRALC) since January 2006. F-15 aircraft schedulers at Robins utilize the full DepotSim scheduling capabilities of DepotSim to perform aircraft level scheduling.
