Analysis of overall equipment efficiency (OEE) of knitting machine varying different operating parameters

Abstract

Overall Equipment Efficiency (OEE) is a tool of Total Productive Maintenance (TPM). Total Productive Maintenance is a plant wide maintenance program, which involves a newly defined concept for maintaining plants and equipment for its entire life span. The goal of TPM is to maximize Overall Equipment Efficiency by increasing production while at the same time, increasing employee morale and job satisfaction. It evaluates efficiency not only in respect of productivity. It takes into account all the basic three components of production: availability, performance and quality to calculate the OEE. All the three components must have higher values, to obtain a higher value of OEE, Garments and Textile industries have already proven its place in the economy of Bangladesh. Most of the industries are private owned and working separately from each other. Though a tremendous success this sector is running with a lot of problem especially during balancing their productivity and working conditions. Like all other industries, this sector also looking for higher profit. It is a simple calculation that if we increase speed with in a limit the productivity of the machine increases. But in this research work it has been analyzed that higher figure for OEE cannot be always considered for a wise decision. This thesis work analyses the OEE of knitting machine to obtain a better environment of knitting section.
