Question

(a) What is the cycle time necessary to achieve the desired rate of production?
(b) Using the longest element rule, create workstations to balance the line,
attempting to get as close as possible to the theoretical minimum number
of workstations.
(c) What is the efficiency and idle time of the line balance?
(d) The company considers that if the lamps are successful with the public
it may need to increase production to 30,000 units. The company thinks
the simplest solution is to obtain two more production lines, thus having
triple capacity. Another option is to re-balance the line. Considering that
a single worker is assigned to a work station, determine which option
(more production lines or re-balancing) yields the smallest labour size.

A company is designing an assembly line for a new line of larmps. It
has identified 10 required tasks and determined the precedence relationship
as in the following Figure. Each circle represents a task and its number the
time to complete the task in minutes. Demand for the product is expected to
be 10,000 units per year. The new assembly line is available for work 8 hour
days, 5 days per week and 50 weeks per year.
