6. [10 points] A plastic bottle manufacturer uses a plastic injection molding machine to make different bottles for different beverages. Plastic injection molding machines are used to make these parts and it is time consuming to clean and re-setup the machines between production runs. Each molding machine and operator works one nine-hour shift with a one-hour lunch break and one-half hour for operator breaks. There are three work orders for the machine. a. What is the total workload (demand) in hours for this work order mix? b. How many machines will it take to do this work in one, two or three days? c. How might this process be improved? Show all computations. 7. [20 points] Hot Dee is a hot sauce producer. The demand forecast for the next four weeks, unit production, and inventory holding costs are given in the table below. Currently, there are 500 bottles on-hand. Due to the contract obligations, no shortages are allowed. At the end of the 4th week, the on-hand inventory must be more than 400 units. a. Use the level production strategy. What is a good production level? What is the total cost? (Production + Inventory holding). Show all work. b. Use the chase demand production strategy. What is the production level for each week? What is the total cost? Show all work. c. Use the minimum cost strategy (optimization with linear programming). What is the production level for each week? What is the total cost? Show all work including Excel Solver parameters or LPSolve model
