A large manufacturer of pencil sharpeners is planning to add a new sharpener, and you have been asked to balance the assembly line with twelve tasks. 500 pencil sharpeners are required daily. The company runs a single shift in a day, and the shift is nine hours long. However, there are two coffee breaks of 10 minutes each and one 45 minutes lunch break, which are not productive hours. The precedence relationships and time requirements for each task are shown as below: (a) Draw a schematic diagram for the manufacturing process. (b) What should the workstation cycle time be in the assembly line in order to meet the daily demand? (c) What is the theoretical minimum number of workstations required to meet the daily demand? (d) Balance the assembly line with minimum number of stations to meet the demand. What is the percentage of total idle time across the entire assembly line? Use following rules: Primary rule: Largest number of following tasks Secondary rule for breaking ties: Longest task time Note: If secondary rule is not successful in breaking the tie, use alphabetical order as your second tie-breaking rule. In order to answer part (d), please fill in a table with column headers given below showing your
