(5 marks) Question 2 (40 marks) A production process includes 15 activities as shown in the table below. These activities are conducted in a production line composed of a number of workstations. The activities, activity durations, and activity precedence constraints are as follows: Activity Preceded by: 1 WN- 1 2 4 5 6 7 8 9 10 11 12 13 14 15 Activity Duration (Seconds) 8 25 15 17 21 18 20 13 12 19 10 11 6 9 7 1 1 4 6,7 5 9 3,8 10 11 12,13 14 The production process is planned to operate for 40 hours per week and must meet the customer demand of 3600 products in each week. (a) Construct the precedence diagram for the above activities of the production process. (5 marks) (b) Calculate the Takt time for the process in order to meet the weekly customer demand.
