-Within each batch, assigning system resources1 in a manner which maximizes resource utilization, i.e. balancing workloads;

-Responding to changes in upper-level production plans с material availability.

All software decision aids typically reside on the FMS computer, or if this not feasible, then on a DSS computer.

FMS Level-3

Operations deal with the real-time operation of the FMS. The functional areas involved are:

-Work-order scheduling and dispatching (which part to introduce next into the FMS, and when);

-Movement of workpieces and material handling system (which machine to send this workpiece to next, which cart to sent to pick up this workpiece, etc.);

-Data distribution; -Tool management;

-System monitoring and diagnostics;

-Reacting to disruptions (failures if one or more system components, sudden changes in production requirements).

During normal system operation, most of these decisions are made by software in the FMS computer and/or MHS computer. However, when failure of a machine occurs, the FMS supervisor will usually take charge of the decision making. The FMS supervisor's task can be considerably simplified by employing various software decision aids which typically should reside on the FMS computer to enable rapid implementation of the changed decisions, but in some systems the architecture could involve use of separate DSS computer as described previously.

« FAMOUS SCIENTISTS:

KONSTANTIN KONSTANTINOVICH KHRENOV»

Konstantin Konstantinovich Khrenov was a Soviet engineer and inventor who in 1932 introduced underwater welding and cutting of metals.

Khrenov dedicated his entire career to the development of welding

techniques and equipment. He invented methods of electric welding and cutting metals under water, designed power sources for arc and spot welding, ceramic fluxes, electrode coatings, methods of cold pressure welding, diffusion welding, plasma cutting and many others. His breakthrough achievement was development of the electrodes for underwater welding in 1932. Their successful test at the Black Sea in the same year was the first practical realization of underwater welding. In this method, the gas bubbles formed as a result of welding reactions were generating a stable flow which shielded the arc from water. Underwater welding had quickly found practical application and already in 1936–1938 was used in the lifting of the ship Boris sunk in the Black Sea, as well as in the repair of bridges and other ships, especially during World War II. For this method, extensively used by the Soviet Navy during World War II, Khrenov was awarded the State Stalin Prize in 1946.
