Operations management studies both manufacturing and services. Queuing is an analytic method for determining waiting time when customers must wait in line to get service. The length of the queue and waiting time can be calculated based on the arrival rate, service rate, number of servers and type of lines.
The goals of S&OP could be classified in these categories: alignment and integration, operational improvement (improvement of the operational performance, improve forecast accuracy), results focused on a single perspective (for instance, improve supply chain performance, improve customer service), results based on trade off (for example ...
