An appliance is to be produced on a single model assembly line. The annual demand for the product is expected to be 374400 units. The facility will operate for 50 weeks/annum, 10 shifts/week, and 8 hr per shift. The work content of assembling the product has been listed in Table 1. The table also includes required times and precedence relationships that must be performed. Transfer time between the stations is 0,04 min Determine

a) Cycle time Tc to balance the line and Service time Ts,

b) Theoretical minimum number of workstations,

c) Apply the Ranked Positional Weight method to come up with a possible line balancing, d) Calculate the balance delay of the purposed assembly line.

d)Calculate the balance delay of the purposed assembly line.
