[rules-users] drl for Selection and Decreasing

Hi, I'd like to use the Planner to determine the location of items to be shipped (aka Order Sourcing). The Planning Entity is: .---------------------. | OrderLine | | ------------------- | | String productCode | | int orderedQuantity | | StockItem stockItem | '---------------------' The resource (Planning Variable) is: .-----------------------. | StockItem | | --------------------- | | String productCode | | String warehouseId | | int availableQuantity | '-----------------------' Solution Implementation is: .-----------------. | OrderPlanning | | --------------- | | score | | orderLineList | | stockItemList | '-----------------' Here's an example to be solved: OrderLine [id=1, productCode=A, orderedQuantity=1] OrderLine [id=2, productCode=B, orderedQuantity=2] OrderLine [id=3, productCode=B, orderedQuantity=2] StockItem [id=1, productCode=A, warehouseId=NYC, availableQuantity=1000] StockItem [id=1, productCode=B, warehouseId=NYC, availableQuantity=1000] StockItem [id=1, productCode=B, warehouseId=CHI, availableQuantity=1000] Can you help me writing the required 'drl'? - StockItem.productCode must be the OrderLine.productCode - StockItem.availableQuantity must be decreased when an OrderLine is allocated Obviously the allocation rules are much more complex. But I'm starting with the Planner and I need help to start. Thanks, Al -- View this message in context: http://drools.46999.n3.nabble.com/drl-for-Selection-and-Decreasing-tp4022...
