Assume that there are 100 workers employed at the beginning of month 1 and zero starting inventory. a. Find the minimum constant workforce needed to meet monthly demand. b. Assume cz= $0.10 per cookie per month, cH= $100, and cp = $200. Add columns that give the cumulative on-hand inventory and inventory cost. What is the total cost of the constant workforce plan? c. Solve for the optimal plan using linear programming. Compare your solution to b.

Problem 1Human visual inspection is necessary in many quality engineering contexts and is naturallysubject to subjectivity. This is especially true for the inspection of solder joints on circuit boards,as there are numerous types of solder defects, as well as a degree to which a joint possessesone or more defect. Consequently, even highly trained inspectors can disagree on the status ofa particular joint. In a batch of 10,000 such joints, inspector A found 724 to be defective,inspect B found 751 to be defective, and 1159 of the joints were judged to be defective by atleast one of the inspectors. Suppose that one of the 10,000 joints is randomly selected.a. What is the probability that the selected joint was judged to be defective by neither ofthe two inspectors?b. What is the probability that the selected joint was judged to be defective by inspector Bbut not by inspector A?
