Abstract - Maynard Operation sequence is most effective
identify that in each process the idle workers are in each process and workforce is not utilized effectively in spare stores.
tool for any enterprise to determine accurate time of the process and improve the productivity of workforce. The work was carried out in spares department of the company. The company provides the Spares parts to retail. Centers & experience centers.
Fig-1: Yamazumi Chart
In spares stores, excess of manpower than the estimation. The workers are working in an Ergonomic risk environment and in the layout multiple movement for completion of Single process. According to the data, cost incurred for the current workforce is 11.2lakhs. It is evident that, there will be an optimization of productivity workforce by using MOST technique, REBA and Single flow technique are implemented. Further, the project can be used as standard to reduce the workforce cost in a spare’s stores. This will result in a future cost reduction of manpower and also Improvement of Productivity.
The yamazumi chart is drawn for workers v/s process in the chart. Inference drawn is the idle workers in each process. The inefficient manpower planning was identified.
Key Words: Electric Vehicle, Maynard Operation Sequence Technique (M.O.S.T), Rapid Entire Body Assessment (REBA), AutoCAD 2D, Goods Receiving Nodes (GRN), Yamazumi chart.
The multiple movements consume more time for the completion of the process.
1. INTRODUCTION
Workers in the packaging department are working in ergonomic risk environment was noticed by high score of REBA so that leads to chances of causing Musculoskeletal diseases in future to the workers.
The project is carried out in the spares department of the company. The observations and statistics of data collected regarding labors productivity, concluded that there is excess man power in the department. It is observed that the workers work in ergonomically risk environment in the department by analyzing the movements of workers using Rapid Entire Body Assessment technique. The process in the spares department includes Non-Value Added (NVA) activities which is to be eliminated and the further work for the improvement of the process.
3. OBJECTIVES To Improve the productivity of workforce and standardization of process activities in the spares department.
2. PROBLEM STATEMENT From one week of observation of spares stores process using yamazumi chart for each process in different timings, its
