Enhancement of Productivity Using Statistical Quality Control Tools. A Case Study in Eicher Tractor a Unit of TAFE Motors and Tractor Limited Mandideep

Abstract

Seven quality tools are one method or tool that is often used in problems solving. Seven quality tools are developed and introduced in Japan by some quality originators such as Deming and Juran. Any organizations that cannot manage the quality of its methods and products have a tendency to fall apart. Quality is crucial to sales, price control, productivity, risk control and compliance. Productivity improvement is one of the core strategies closer to production excellence and it is also necessary to achieve correct monetary and operational performance. It enhances client delight and decrease time and cost to expand, produce and deliver merchandise and carrier. Productivity has a positive and big relationship to performance measurement for manner utilization, system output, product costs, and work-in-process stock tiers and on-time shipping. development can be in the form of elimination, correction (restore) of ineffective processing, simplifying the procedure, optimizing the machine, decreasing variant, maximizing throughput, reducing fee, enhancing high-quality or responsiveness and lowering set-up time. Hydraulic systems are widely employed in most of industries like for rollers, cement industries equipment’s etc. used for high force movements to obtain motion in the process. And in the large scale industries all the facilities are provided for maintaining the efficiency of the hydraulic system, since they have investments and experienced personals. In this study elimination of major dismantling at sick bay at Eicher Tractor, Bhopal was done by applying seven quality tools. The main aim of this thesis is to provide an application of seven QC tools to improve the quality level. QC tools are the means for Collecting data, analysing data, identifying root causes and obtaining the results. All of these tools together can provide great process tracking and analysis that can be very helpful for quality improvements. These tools make quality improvements easier to see, implement and track. Findings revealed that 150 pieces of ADDC cylinder checked after action implementation and found no leakage during testing and 129 cylinders fitted in ADDC housing, where no droppage was observed at load testing machine and 86% productivity improved.
