Completely and thoroughly explain how Control Charts could be used by a company that makes Eyeglass Lenses to improve the manufacturing processes they use to make eyeglass lenses.
The company can use the variable as well as attribute charts to improve the manufacturing process in following manner.
(a) Company can identify certain crucial properties of the eyeglass lenses such as the thickness of the lens utilising the running data, collected in form of samples taken at regular intervals such as once every shift of 8 hours. If there are 8 machines, one sample from each would make it 8 per shift. If this exercise continues for 10 days, we have sets of 8 samples each. The average as well as range ( difference between the highest value and the lowest value in a set of 8) can be noted. Now the average of the averages ( xbarbar) and average of ranges ( rbar) can be calculated. The Xbar and R chart can be prepared with help of statistical methods and can be used to find if both the values ( xbar and R) are within conrol limits. The pattern of variation of data can be used to find if the process has an assignable cause or it is just random variation.
(c) The attributes can also be used to construct the charts ( p chart, c chart ), These attributes are inform of number of defects or fraction of defects which can be calculated from a sample of taken at random and finding out number of defects in it. Ten or twenty or more of such samples of 100 each can be used to find out the average fraction defective and construct the charts to find out if the process is under control limits or not. If the process is found to produce more defects, it can be rectified accordingly.

Completely and thoroughly explain how a Predetermined Time System, such as MTM or MOST, could be used to establish labor standards for a company that makes any type of metal products. Be specific in your answer and identify as many different specific examples as you can where a Predetermined Time System could be used to establish engineered standards for the different operations that are required to make any type of metal products
Completely and thoroughly explain how a Proposed Income Statement and a Proposed Return on Investment (ROI) could be used to make a decision on whether or not to add a new product to the existing product line of a company that makes frozen food products.
Completely and thoroughly explain how the concepts of Engineering Economy could be used to help a construction contracting company decide on whether they should invest in new equipment. You will need to include more information than what is presented in the lecture transcript for Engineering Economy.
Completely and thoroughly explain how total product costing could be used in grocery store to determine how set prices for the items they sell so that those items include all of their costs such as labor, shipping costs, utilities and shelf space in the grocery store and the grocery store earns a reasonable and acceptable profit.
Completely and thoroughly explain the entire Manufacturing Process in a factory that makes any type of Glass product. The manufacturing process should be complete from the very first step in the process all the way through the final step in the process that makes the finished Glass product. Do not simply describe one phase of the overall process – describe the entire process from beginning to end.
Explain how process improvements using control charts are used to support areas of industry research, academic research, and scientific research.
