The interaction is triggered when goods in the warehouse of a SM are depleted and the SM has to order from its DC to refill stock. The following steps are followed as illustrated in Figures 5.2 and 5.4(a) : 1. A SM sends an order to its DC. 2. The DC sends a confirmation to the SM and ships the ordered goods. 3. Goods are registered by RFID readers upon leaving the DC warehouse. 4. The DC sends information about the transaction to the HQ (sales statistics). 5. The shipment arrives at the SM and is registered by RFID readers upon entering the SM warehouse. 6. A confirmation is sent to the DC. Interaction 2: Order/Shipment Handling between DC and SP This interaction exercises persistent P2P and pub/sub (durable) messaging between the DCs and SPs. The interaction is triggered when goods in a DC are depleted and the DC has to order from a SP to refill stock. The following steps are followed as illustrated in Figures 5.3 and 5.4(b) : 1. A DC sends a call for offers to all SPs that supply the types of goods that need to be ordered. 2. SPs that can deliver the goods send offers to the DC. 3. Based on the offers, the DC selects a SP and sends a purchase order to it. 4. The SP sends a confirmation to the DC and an invoice to the HQ. It then ships the ordered goods. 5. The shipment arrives at the DC and is registered by RFID readers upon entering the DC’s warehouse. 6. The DC sends a delivery confirmation to the SP. 7. The DC sends transaction statistics to the HQ.
