Simulation Based Process Design Methods for Maintenance Planning

Abstract

The primary objective of this work is to use simulation methods for the development of optimal service support procedures using an integrated Product, Process and Resource (PPR) structure. Mid life fatigue modifications required on a sub-system within an existing aerospace platform have been used to demonstrate the utility of this approach in supporting the transition of an original equipment manufacturer (OEM) to availability contracting. Other objectives of the work were to show how significant cost drivers can be identified and quantified through the virtual development of work breakdown structures (WBS) for service support processes and to show how the mechanisms used to develop optimal processes, can produce animated instructional materials which enhance organisational learning as processes evolve. This supports the effective communication of methods and work breakdown structures between the technical author and service personnel. Although this work has been completed using an aerospace sub-system as a demonstrator, the outcomes are equally applicable to other platforms which utilise complex engineering systems. The results of this work have system level significance in reducing risk in service provision through the support of value co-creation. The simulation outputs also provide data for higher level cost modelling which in turn, informs the strategy required for supply chain engagement through incentivisation.
