customer order process, production scheduling and production

It’s a typical pattern of interaction between customer order process, production scheduling and production. The key point: production has its own rhythm, it does not rush immediately to fulfill a customer’s order. Instead, customers order are converted into production orders, the latter are stored in the database for some time, and then at some regular intervals (e.g. daily) the production planning process starts which calculates a production schedule for given production orders. As soon as the schedule is fulfilled instances of the customer’s order process receive messages that the order is produced and theу proceed to delivery. Two methods of interprocess communication are involved in this case: via data objects and messages.
