Ranging from Operation Desert Storm to combat actions in the Balkans, EA-6B Prowler aircraft lie at the heart of nearly all tactical aircraft strikes. Providing a fleet capable of such combat actions in the next decade challenges the Prowler community to efficiently schedule EA-6B depot maintenance services. By 2009, EA-6B depots must conduct 80 wing center section replacements, 144 major aircraft modifications and standard depot level maintenance 154 times. There are several complex rules governing when each Prowler is eligible for each service; these rules are also flexible enough to allow more induction schedules than can be evaluated manually in a reasonable amount of time. Since each service removes aircraft from mission inventory for six to 12 months and performing multiple services together requires less time than performing services independently, services should be combined whenever possible. This thesis develops a mixed integer linear program, EA-6B Depot Maintenance Optimization Model (EDMOM), to help schedule EA-6B aircraft for depot maintenance services. EDMOM minimizes total time aircraft are removed from mission inventory; it produces an induction schedule for the EA-6B fleet through 2009 that adheres to all appropriate rules and conducts 378 services in only 216 inductions, requiring 2,446 total months. Without combining services, it would require 3,630 months, nearly a 50 percent increase.

Download Optimally Scheduling EA-6B Depot Maintenance and Aircraft Modification Kit Procurement Book in PDF, Epub and Kindle
The Department of the Navy maintains a fleet of 124 EA-6B aircraft, the only tactical electronic warfare aircraft in the Department of Defense inventory. Already 30 years old and not to be retired until 2015, the EA-6B requries depot maintenance services to remain combat ready. EA-6B aircraft undergo standard depot level maintenance (SDLM) about every eight years. In addition to SDLM, depots must complete 72 wing center section replacement services and over 175 major aircraft modification services by 2010. Navy regulations govern when each EA-6B is eligible for each service; these rules are flexible enough to allow more induction schedules than can be evaluated manually in a reasonable amount of time. Because each service keeps an aircraft at the depot for six to 14 months and performing multiple services together requires less time than performing services independently, services should be combined whenever possible. This thesis introduces DMAAP (Depot Maintenance And Acquisition Planner); a prototypic optimization based decision support tool to assist in scheduling EA-6B depot level maintenance services and major aircraft modification kit acquisition. DMAAP produces a Master Plan (induction schedule) providing a monthly schedule for the first six years, a yearly schedule out to 2013 and yearly major aircraft modification kit acquisition levels out to 2010. We compare DMAAP Master Plans obtained using alternate depot induction policies to demonstrate DMAAP's ability and show how yearly depot workloads and yearly operational aircraft vary under alternate policies.

Download Shop Floor Scheduling for Program Depot Maintenance Considering Stochastic Repair Needs Book in PDF, Epub and Kindle
The research supported by this grant investigated new methods to schedule aircraft depot maintenance activities while considering resource constraints and the stochastic nature of task durations. Depot maintenance can be characterized as a large and very complex project scheduling problem. The research resulted in the development of a new method to identify the critical path within resource-constrained project scheduling problems, heuristic search methods that improved overall project completion time by an average of nine percent on test problems, look ahead scheduling methods which further improved project duration, heuristics for improved scheduling when using common resources on multiple projects simultaneously, and heuristics which improved the scheduling of resource-constrained problems when multiple execution modes are available for each task. A windows-based software application was developed which allows a practitioner to use a combination of these methods in order to create good solutions to this complex depot maintenance scheduling problem.

Download A Survey of Aircraft Structural-life Management Programs in the U.S. Navy, the Canadian Forces, and the U.S. Air Force Book in PDF, Epub and Kindle
The average age of aircraft in the U.S. Air Force is 22, making aging an increasing concern. The Air Force program responsible for maintaining the structural safety of its aircraft faces challenges, however, such as budgetary pressures, regulations, and communication issues. The authors sought insights on these issues by comparing similar programs in other services. Their observations suggest the value of clear policies, independent assessments, standard metrics, and open and clear communication.
