A toy manufacturer makes its wind-up motors, which are then put into its toys. While the toy manufacturing process is continuous, the motors are intermittent flow. Data on the manufacture of the motors appears below. (a) To minimize cost, how large should each batch of subassemblies be? (b) What is the total annual inventory cost (holding plus setup) of the optimal behavior in this problem?

Transcribed Image Text:Annual demand (D) = 25,000 units
Setup cost (S) = $85 per batch
Carrying cost = $2.00 per unit per year
Daily subassembly production rate = 1,000
Daily subassembly usage rate = 400
