Essay

A toy manufacturer makes its own 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.
Annual demand (D)= 50,000 units Daily subassembly production rate = 1,000
Setup cost (S)= $85 per batch Daily subassembly usage rate = 200
Carrying cost = $.20 per unit per year
(a)To minimize cost,how large should each batch of subassemblies be?
(b)Approximately how many days are required to produce a batch?
(c)How long is a complete cycle?
(d)What is the average inventory for this problem?
(e)What is the total annual inventory cost (holding plus setup)of the optimal behavior in this problem?
