Jacobs' distribution network consists of a single factory and a single warehouse, both in Calopeia. The warehouse only supplies air conditioner retrofit kit manufacturers, who are all in Calopeia.

Jacobs produces its chemical in batches, loads the chemical into small plastic drums, and then transports the drums from the factory to the warehouse by truck. The warehouse sends drums to customers as orders are received. The cost of fulfilling an order, including the cost of mailing the drum to the customer, is $150 per drum.

The current capacity of the factory is 20 drums per day. More factory capacity can be purchased at a cost of $50,000 per drum per day. For example, expanding the capacity by 10 drums per day for a total of 30 drums per day would be (10)$50,000 = $500,000. Capacity costs are incurred as soon as the capacity expansion begins. It takes 90 days to complete a capacity expansion. Capacity cannot be retired.

Production in factories is carried out in batches, where each batch is an integer number of drums set by you. The cost to produce one batch equals $1500 plus the number of drums in the batch times $1000. For example, the cost to produce a batch of 10 drums is $1500 + (10)$1000 = $11,500.

The batch of finished drums is shipped from the factory to the warehouse as soon as production of the batch is completed. The drums can be shipped either by truck or one at a time by mail. One truck can carry 200 drums. One truck making a trip from the factory to the warehouse costs $15,000, regardless of how full the truck is. It costs $150 to mail one drum from the factory to the warehouse. Transportation times from the factory to the warehouse are 7 days for the truck or 1 day for mail. There is no practical limit to the number of drums a warehouse can hold.

Both the costs of producing the batch and then shipping it to the warehouse are incurred as soon as production of the batch starts. If there is insufficent cash to pay for the production and shipping of the batch, the factory will remain idle. Production of a batch is triggered when the finished goods inventory (both en route to the warehouse and in the warehouse) fall below the order quantity, which is set by you.

Jacobs pays insurance and other out-of-pocket holding costs on chemicals once production is complete. These holding costs for one drum for one year equal $100, whether the drum is en route to a warehouse or the drum is physically in the warehouse. There are no such holding costs for work-in-process inventory in the factory. Jacobs earns 10% per year on its cash, compounded daily.
