The MES concept describes an area of functionality rather than a specific type of system, namely the area in a classical system hierarchy between high level planning systems (MRP II systems or ERP systems) and shop floor control (which includes both manual and automated process control systems). MES systems support manufacturing processes by providing planning, execution and reporting functions.

In the research field of MAS, a very important topic is the study of control methods for manufacturing devices, from NC machines to automatic guided vehicles. But the focus of this chapter is on studying MAS from the CIM system point of view. We wiU describe the shop-floor control and management system functions and components below.

Tool management is also a very important task for the shop-floor control and management system. In a manufacturing system, a large number of tools are needed and the supply of necessary tools on time is vital for improving productivity. Tool quahty is important to product quality. The parameters of every tool should be maintained in a correct and real-time fashion because these parameters will be used by machine centers in controlling manufacturing processes. 

Quality control, production monitoring, fault diagnosis, and production statistics are important supplementary functions for the shop-floor control and management system to be operated efficiently and effectively. 

The application enabling level, which utilizes the functions contained within the system enabling level, is composed of three domain sub-integration platforms (SIPs) MIS SIP, CAD/CAM/CAPP SIP, and shop-floor control SIP. Each SIP is designed according to the requirements of a domain apphcation and provides functions for applications in the form of Application Dependent API (AD API). The AD API functions are designed specifically to enable the quick and easy development of...

The sequencer and shop-floor control module of a scheduling system may track the work in progress as well as the status of the machines. It performs reactive scheduling functions based on this informtion. Such a module may be based on the axiom of locality, which impUes that if an unexpected event occurs, an effort is made to timit, as much as possible, the number of changes in the existing schedules when correcting the problem.

Shop floor control, which refers to production management techniques for collecting data from factory operations and using the data to help control production and inventory of the factory. 

Shop floor control systems are responsible for allocating resources in the forms of labor, tooling, and equipment to the various orders on the shop floor. They use information provided by the planning systems in order to identify those orders for which action must be taken (Chryssolouris 2006) (Fig. 7). 

The Shop Order A central focal point for any shop floor control system is the shop order, which is released by the planning system to the shop floor. All of the activities undertaken by the shop floor control system are directed at ensuring the timely and efficient completion of the shop order.

In Figure 9.2, the shop floor control function is shown by the box labeled Production Activity Control. This is a short-range tracking function, which watches the progress of jobs through the shop, determines when to release more work (Input/Output Control), and determines the specific sequences of conducting work at the individual work centers. 

The planner now releases the job to the shop floor, and orders for purchased materials are released to the vendors. The shop floor control system controls the actual flow of the work through the shop floor. 

Site Recipes, which typically reside on manufacturing execution systems (a layer that lies between plant floor control and ERP systems). Site recipes define local site control of recipes across different hardware platforms, such as those supplied by control systems manufacturers, like Honeywell, Fisher-Rosemount, Rockwell Automation, ABB, etc. 

While alarm cheek valves are devices for the main risers, it would be impossible to put these alarm valves after every special hazard control valve. Even floor control valves would not usually have alarm check valves. The paddle or vane t5q)e alarms are best suited for these areas. They are less desirable for main risers since they sit in the stream of water. There have been cases where the paddle is corroded off at the arm. This can be discovered by regular testing but this could leave the pieces in the system. Since they would only be carried in the stream by water in a totally gridded system, you would have no idea at what point the debris would stop.
