Question

1.An assembly line with 28 activities is to be balanced. The total amount of time required for all 28 activities is 39 minutes. The longest activity is 2.2 minutes and the shortest is 0.8 minutes. The line will operate for 450 minutes per day. What is the assembly line efficiency with 11 stations and a product produced every 5 minutes?

2.An assembly line consists of 3 tasks with individual times 5, 3, and 2 minutes and the cycle time of 5 minutes. Calculate the theoretical minimum number of workstations.

3.Which type of layout is best for high volumes of demand with few if any setups/changeovers?

Select one:A. ProductB. ProcessC. CellularD. Fixed position

Answer 1

1)

The first step is to find the cycle time which is found using the following equation

Cycle time Production time available per day 450 Units required per day 90

Cycle time = 5 minutes

Assembly line efficiency= Sum of the task times x 100 = Number of work stations x Cycle time 39 11 x 5 x 100

Assembly line efficiency = 70.91 %

2)

39 Theoretical number of work stations Sum of the task times Cycle time 5

Theoretical number of work stations = 8

-------------------------------------------------------------------------------------------------------

3) The correct answer is option A

Explanation:- Product focused layouts are capable of producing high volume of standardized outputs while also reducing the number of setups/ changeovers. The reduction in the number of setups/changeovers is possible because the layout is centered around one type of product.
