Problem 3 The assembly of a dresser requires 9 tasks. The tasks, their precedence relationships, and the task times in minutes are given in the following table: a. Draw a precedence diagram that shows the precedence relationships among tasks for this assembly operation. b. If 200 dressers are to be assembled in a 40 -hour work week, what is the cycle time? c. What is the minimum number of workstations required to balance this assembly line? d. Assign tasks to workstations using the most-following-tasks rule as the primary rule and the ranked-positional-weight rule as the secondary (breaking tie) rule. e. Compute the balance efficiency and percent delay (percent idle time)
