(Note: 1 ton = 2,000 pounds.)
a. How many bags per nm are optimal?
b. What would the average inventory be for this lot size?
c. Determine the approximate length of a production run, in days.
d. About how many runs per year would there be?
e. How much could the company save annually if the setup cost could be reduced to $25 per run?

Suppose we schedule shipments to our customers so that we expect each shipment to wait for two days in finished goods inventory (in essence we add two days to when we expect to be able to ship). We do this as protection against system variability to ensure a high on-time delivery service. If we ship approximately 2,000 units each day, how many units do we expect to have in finished goods inventory after allowing this extra time? If the items are valued at $4.50 each, what is the expected value of this inventory?

The Handy Manufacturing Company manufactures small air conditioner compressors. The estimated demand for the year is 140,000 units. The setup cost for the production process is $200 per run, and the carrying cost is $10.00 per unit per year. The daily production rate is 100 units per day, and demand has been 50 units per day. Determine (a) the number of units to produce in each batch. (The problem assumes 240 operating days.) and (b) the ordering cost
A food processor uses approximately 27,000 glass jars a month for its fruit juice product. Becauseof storage limitations, a lot size of 4,000 jars has been used. Monthly holding cost is 18 cents perjar, and reordering cost is $60 per order. The company operates an average of 20 days a month.a. What penalty is the company incurring by its present order size?b. The manager would prefer ordering 10 times each month but would have to justify any change inorder size. One possibility is to simplify order processing to reduce the ordering cost. What orderingcost would enable the manager to justify ordering every other day (i.e., 10 times a month)?
