Consider the operations given in table. 47 feet of the floor space along the conveyor is available for installing assembly stations around a closed loop conveyor system. Eeach station is made 5 feet long in order for the operators to work comfortably, and at least 1 feet clearance between stations
(except between input and output stations).

• Find the maximum number of stations on conveyor when the target production rate is 90 units per hr.

• Find the maximum number of stations on conveyor when the target production rate is 120 units per hr.

• Find the speed of conveyor when target production rate is 90 units per hr.

• Find the speed of conveyor when target production rate is 120 units per hr.

• Find the task to workstation assignments with Largest Candidate Rule when the target production rate is 90 units per hr.

• Find the total space occupied by the workstations and clearances when the target production rate is 90 units per hr.

• Find the task to workstation assignments with Largest Candidate Rule when the target production rate is 120 units per hr. Adjust the station-sizes using the method we covered in the class.

• Find the allocated space occupied to each workstation, and total space occupied including clearances when the target production rate is 120 units per hr.
