Answer:

hello your question is incomplete attached below is the missing table to your question

Illinois​ Furniture, Inc., produces all types of office furniture. The​ "Executive Secretary" is a chair that has been designed using ergonomics to provide comfort during long work hours. The chair sells for​ $130. There are 480 minutes available during the​ day, and the average daily demand has been 50 chairs. There are eight tasks

answer : a) 9.6 minutes

               b) 5 work stations

               c) choose initial task and task with maximum task time

               d) 21 minutes

Explanation:

A) cycle time for the production of a chair

cycle time = (production time available per day ) / ( unit demand per day )

                 = 480 minutes / 50 chairs

                 = 9.6 minutes ≈ 10 minutes

B) theoretical minimum number of workstations

    = Total task / cycle time

 where total task = (4 + 7 + 6 + 5 + 6 + 7 + 8 + 6 ) = 49 minutes

             cycle time = 9.6 minutes

hence theoretical minimum number of workstations = 49 / 9.6 = 5.1

 ≈ 5 workstations

C ) Assignment of tasks to workstations

      attached below

you will choose the initial/first task and also the task with maximum tax time

D) For the process the total idle time per cycle

total idle time = summation of all idle times for the 8 tasks = 21 minutes

Task A, C = 0 minutes

Task B = 3 minutes

Task E = 4 MINUTES

Task F = 3

Task G = 2

Task H = 4

Task D = 5
