A System Simulation of the Execution of Scheduled Maintenance at a Minuteman Missile Wing
Abstract
Minuteman Missile maintenance is performed in a highly dramatic and complex environment. Strategic deterrence depends in part on the capability of the maintenance organization to be responsive to this environment. However, maintenance efficiency is also important. Scheduling effectiveness is a primary measure of this efficiency. Scheduling effectiveness is the ratio of workorders completed to workorders scheduled. Deviations occur which prevent scheduled workorder completion. These are either controllable by wing level managers, or uncontrollable. The primary controllable factor is personnel error. This research focuses on the determinants of scheduling effectiveness, and the possible effects of management action to reduce the number of controllable deviations. Wing level source data is examined, and a Q-GERT simulation is developed. Sensitivity analysis is performed on the model. Two independent variables, personnel error and vehicle and equipment problems, are varied and the resulting effect on the scheduling effectiveness rate is measured. Using the assumption that equal levels of management attention will produce equal percentage reductions in the incidence of personnel errors and vehicle and equipment deviations, the model shows that the personnel error factor has the greater impact on scheduling effectiveness. Several insights are presented along with recommendations for facilitating further research in this area.
