Military organisations today operate small fleets of unique aircraft and need to be sure that the spares purchased to support operations meet the organisations needs whilst remaining the minimum necessary to minimise unnecessary government expenditure. Historically this task was undertaken by using historical consumption as the basis of the calculation. This is not seen as appropriate today and a range of deterministic models are used to produce the spares lists. However, their failure to apply a particular flying programme means that the output is viewed with some scepticism by military staffs. Simulation provides the means to apply that flying programme and, moreover, allows a series of what if evaluations to be undertaken. This thesis covers the work undertaken by myself to design and produce a suitable simulation application to meet the above requirement. Whilst data was available it was of a simple form without sufficient fidelity to allow the underlying distributions to be derived. Consequently, the opportunity to examine the effect of applying different distributions for both failure and repair times was taken allowing the scope of the work to broaden. Having produced the simulation a number of alternative flying programmes were simulated to identity their impact on the overall achievement and aircraft availability. This work has allowed me to not only provide a model which can be used with a deterministic application to assess the validity of the spares list but, has also allowed investigation into the effect of applying different distributions to both failure and repair times.

Abstract

Military organisations today operate small fleets of unique aircraft and need to be sure that the spares purchased to support operations meet the organisations needs whilst remaining the minimum necessary to minimise unnecessary government expenditure. Historically this task was undertaken by using historical consumption as the basis of the calculation. This is not seen as appropriate today and a range of deterministic models are used to produce the spares lists. However, their failure to apply a particular flying programme means that the output is viewed with some scepticism by military staffs. Simulation provides the means to apply that flying programme and, moreover, allows a series of what if evaluations to be undertaken. This thesis covers the work undertaken by myself to design and produce a suitable simulation application to meet the above requirement. Whilst data was available it was of a simple form without sufficient fidelity to allow the underlying distributions to be derived. Consequently, the opportunity to examine the effect of applying different distributions for both failure and repair times was taken allowing the scope of the work to broaden. Having produced the simulation a number of alternative flying programmes were simulated to identity their impact on the overall achievement and aircraft availability. This work has allowed me to not only provide a model which can be used with a deterministic application to assess the validity of the spares list but, has also allowed investigation into the effect of applying different distributions to both failure and repair times.
