Constructor Detail

SimpleDemandManager

public SimpleDemandManager()

Method Detail

calculateCosts

private void calculateCosts()

Predicts replacement costs for each type of component and computer

predictSalesPrices

private void predictSalesPrices()

Predicts the price that each type of computer will sell for.

getProductionDays

private void getProductionDays()

Determines how many days of production should be planned for.

setupResources

private void setupResources()

Initializes the resources - cycles, components, and completed computers.

produceExistingOrders

private void produceExistingOrders()

Tries to deliver or produce existing orders. Orders are sorted by profit, then considered one at a time. Orders that are due or late will be delivered if possible. Other orders will not be delivered yet. An attempt will be made to produce each order up to its cancellation date.

handleRFQs

private void handleRFQs()

Makes offers on RFQs. A fixed offer price is used for each type of computer. RFQs are sorted in order of profit, then considered one at a time. An offer will be made for any RFQ that can be produced in time. To make sure that some cycles are reserved for RFQs on future days, only some of the remaining cycles are made available.

tryToProduce

private boolean tryToProduce(int index,
                             int quantity,
                             int daysUntilDue)

Tries to produce the needed computers. The computers will be produced using cyles and components from the latest possible days. If not all computers can be produced, the remainder will be taken from already completed computers if possible.

Parameters:

index - computer index

quantity - how many are needed

daysUntilDue - how far in the future the due date is

Returns:

whether production was possible

sendProductionSchedule

private void sendProductionSchedule()

Determines the production schedule for tomorrow, and sends it to the factory. If there are free cycles, projected production from future days is moved forwards.

projectFutureComponentUse

public void projectFutureComponentUse()

Project component use for some number of days in the future, so the supply manager will know what to order.

produceDeliverBid

public void produceDeliverBid(GameSettings settings,
                              DailyInfo dayInfo,
                              AgentInfo agentInfo,
                              DailyActions actions)

Performs all of the demand manager's actions: produce and deliver computers, and bid on RFQs from customers.
