A production line of a mechanical spare part includes three stages such as moulding, finishing and packing. As the production engineer, you are required to improve the efficiency of the process immediately to cater a relatively large order which needs to be served in a limited time. On the shutdown day you only have resources and time to do detailed maintenance in only one component. In order to do that you are required to identify the component(stage) which affect the most to the total time consumed. Following details were obtained in a cycle time analysis of most recent week. Using these details find the most significant component by performing a correlation analysis.

On the shutdown day you only have resources and time to do detailed maintenance in only one component. In order to do that you are required to identify the component(stage) which affect the most to the total time consumed. Following details were obtained in a cycle time analysis of most recent week. Using these details find the most significant component by performing a correlation analysis. Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Average time for Total 35.5 31 40.5 34 39 37.5 process Average 15 20 17 25 18 24 20 time for Moulding Average 4.5 7 7 5.5 time for finishing Average 10 11 8.5 10 12 time for packing Factory manager claims that there is a positive relationship between moulding time and total time taken for the process. As the production engineer you need to test this hypothesis using the above data. If there is a relationship, provide the best fitted straight line for the above data using linear regression. You should interpret your results ir 00 31 6.
