PERFORMANCE MANAGEMENT OF TOKEN BUS NETWORKS FOR COMPUTER-INTEGRATED MANUFACTURING

This paper focuses on performance management of computer communication networks serving computer integrated manufacturing systems. The perfo rmance management aims to improve the network performance in handling various types of messages by on-line adjustment of protocol parameters . The principle of fuzzy logic has been used in formulating the perfor mance management rules and in deriving management decisions. Three typ es of the fuzzy performance management have been developed for IEEE 80 2.4 protocol standard and have been evaluated via discrete event simul ation.
