Many efforts have been taken to maintain and improve the availability of aircrafts and the mission capabilities of aircrafts in operation. The related Key Performance Indicators (KPI) are, beside others, the aircraft availability rate and the mission capability rate. Cost savings, limited numbers of available aircrafts and the demand for specific operational capabilities to be provided by the aircrafts are the main drivers to improve these KPIs. Civil airlines as well as air forces are the main stakeholders to limit the maintenance costs on one side and to guarantee a high degree of aircraft availability on the other side. Especially military applications have an increasing demand to keep the mission capabilities of a limited number of available aircrafts in order to fulfil the operational tasks. Hence the main goal is to enhance the Value in Operation of future Air Systems. At present Mission Planning, Operational Scheduling, Maintenance Planning and Health Monitoring are mainly isolated functions: Limited knowledge about Maintenance Planning is available for Mission Planning and Operational Scheduling Flight specific stressors on the aircraft structure and components health condition are not sufficiently taken into consideration by Maintenance Planning. Maintenance and repair and Operational Scheduling are without predictive capabilities. Health monitoring information is not considered for Operational Scheduling. The objective of the technology project described herein is to enhance the Mission Capability Rate on the operational level and the Mission Availability Rate on the technical/logistical level. Within the concept of Prognostics based Mission Planning the involved process elements Mission Planning, Operational Scheduling, Maintenance Planning and Health Monitoring are not performed in an isolated manner any more. The Mission Availability Rate is expected to be improved by bridging Mission Planning and Maintenance Planning. Information is fused to provide prognostic capabilities. The concept will be based on Operational Risk Assessments using the mission information (plans) of the aircrafts involved in a collective operation. It improves the decision making process by injection of additional information indicating operational risks for current or future missions by prediction of aircraft capabilities degradation caused by the executed missions. The outcome than feeds the rule based decision support engine, modelling the business rules of mission, fleet and maintenance planning with the aim to improve the mission availability rate. The herein specified functional components Mission Planning, Operational Scheduling and Operational Risk Assessment (ORA) in conjunction with Maintenance Planning and Health Monitoring are implemented in a demonstrator framework.
