- Abstract
In the era of advancement in technology and global competitiveness the traditional maintenance practices have
become obsolete. Also in recent years sophisticated and more advanced equipments have been augmented in the
armed forces hence, the role of maintenance workshops/ engineers has become very challenging. Therefore,
analyzing various maintenance issues and the associated risk has become very important in the armed forces.
Preventive maintenance practices assist in improving the reliability of assemblies and how it will be effective for the
equipments of armed forces is illustrated in this article. Gear box assembly used in the medium size vehicles are
considered for the analysis and the failure data in various operating conditions is taken from the logbooks of the
vehicles. For modeling purposes the Weibull distribution has been chosen (since it has practical utility-ability to model
products/systems consisting of large number of components and may have increasing/decreasing or a constant failure
rate). The result will be useful to the maintenance engineer to find the unreliability of the gear box assemblies and also
for future strategic decision making.
- Keywords: Weibull distribution; reliability; preventive maintenance; strategic decision making.
