” 写作GO编程实验、GO lang 设计程序调go编程写作Homework for Quality Management and Statistical Process ControlDue on Dec. 18th, Friday in ClassPLEASE SHOW DETAILED CALCULATION WORK FOR EACH PROBLEM!PLEASE WRITE YOUR NAME AND ID NUMBERS CLEARLY ON THE FRONT PAGE!ALL PAGES SHOULD BE STAPLED!Problem 1A manufacturing company wants to use control charts to monitor a continuous process to cut plastic tubesinto standard lengths. Samples of five observations each were taken yesterday, and the results are in thetable below.1. Using these Sample data to construct appropriate control charts to monitor the future cutting process.Sample1 2 3 4 5 679.1 80.5 79.6 78.9 80.5 79.778.9 78.8 79.7 79.4 79.5 80.680.5 81.0 80.4 79.8 80.4 80.578.4 80.4 80.3 81.3 80.7 79.081.0 80.1 80.8 80.6 78.8 80.12. Four more samples of the same size have been taken today, and the results are given below. Based on thecontrol charts you constructed, did you notice any major changes in todays cutting process?Sample 1 (today) Sample 2 (today) Sample 3 (today) Sample 4 (today)78.0 81.0 79.0 79.182.5 82.0 82.2 81.080.0 81.5 83.1 78.881.5 82.2 80.0 79.679.0 82.3 79.5 82.0Problem 2An automatic screw Machine produces hex nuts. If a hex nut does not meet the quality standard, it isconsidered as defective. Samples of 200 hex nuts each were taken to monitor the production. The number ofdefective hex nuts from the past 13 samples is listed below. Construct an appropriate control chart anddetermine whether or not the process is in control. (Hint: The quality here is measured by defective rate)Sample1 2 3 4 5 6 7 8 9 10 11 12 13# of defectives 1 2 2 4 2 4 2 1 2 10 3 2 1Problem 3The postmaster of a small western city receives a certain number of complaints about mail delivery eachday. The number of complaints in the past 14 days is given below. Construct a control chart to see if thequality of mail delivery is in control (stable)?Day1 2 3 4 5 6 7 8 9 10 11 12 13 14# of complaints 4 10 14 8 5 6 3 11 9 7 5 4 2 10Hint: For Problem 2 and 3, use the data in the table to construct respective control charts and plot the samedata on the charts constructed.Problem 4Answer the following questions for a single sampling plan with sample size n = 80 and c = 31. Draw the OC curve for the sampling plan, using the Poisson table distributed in class2. If AQL = 2% and LTPD = 7%, what would be the producers and consumers risks associated with thesampling plan?3. If the sampling Plan is used to inspect a lot of 10,000 products with an average defective rate of 3%,what would be the average quality after inspection, assuming all the defectives will be replaced ifdetected?Problem 5 (Bonus Question, 10 pts)Consider the following three-stage production process of glass ceramics, which is operated as a workerpaceline.Components 6 min/unit 5 min/unit 4 min/unit Finished UnitsThe process is experiencing severe quality problems related to insufficiently trained workers. Specifically,20 percent of the parts Going through operation 1 are badly processed by the operator. Rather thanscrapping the unit, it is moved to a highly skilled rework operator, who can correct the mistake and finish upthe unit completely within 15 minutes. The same problem occurs at station 2, where 10 percent of the partsare badly processed, requiring 10 minutes of rework. Station 3 also has a 10 percent ratio of badlyprocessed parts, Each of them Requiring 5 minutes by the network operator.1. What is the process yield? (Remember, process yield is the percentage of good units that are processedthrough the overall process.)2. What is the process yield without hiring the skilled rework operator?1 2 3如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
