only question 3

Question #2 (15 Points) The result of a detailed study of setup procedure on a molding machine is shown in Table 1 below. The setup involved removing an old die and installing a new one. Tahle I InternalTime Performed by External?(min) Step# Setup 1 Check in at operation, go to die storage 2 Transfer new die 3 Remove old die 10 Setup person 16 Setup person 20 Setup person 20 Setup persorn 30 Operator 24 Setup person 40 Setup person Return old die to storage 5 Get new material Attach new die 7 Adjust machine What you need to do: 1)- define internal and external setup elements (1-2 line each. Classify the elements into internal and external setup operation (fill the corresponding column) 2)-Determine the % of current setup time that you classify as internal, what the minimum (ideal) setup time? 3)- Suppose we modify the procedure and in the new procedure step 5 takes 45 minutes and step 6 takes 27 minutes. How long should the setup procedure take Question 3 (10 points) in Question #2 , suppose at present condition, the operator and the setup person are paid $15 and $20 per hour respectively. The production rate is 4 units per hour and material cost per unit of product is S1.5. If the batch size is 49 units and product is sold for $9.6 per unit, determine 1)- actual production cycle time, 2)-the resulting % profit PART I. Prohlems
