Life-cycle Assessment on the Highway Street Lantern using Weibull Probability Approach

Predictive maintenance (PM) evaluates the condition of equipment by performing periodic or continuous equipment condition monitoring. This paper presents a Weibull statistical approach, in order to determine life cycle of highway street lighting. The historical data that collected from the maintenance checklist record of 250 and 400W street lighting lanterns replacement for 2 years of period were used. Than, two key performance indicators which shape factor, β and characteristic life, η were determined to perform the Weibull probability analysis. The findings show that estimation of mean time to failure (MTTF) for 250 and 400 watt bulb are 4009.30 and 5043.36 hours period of operation respectively.
