Performance analysis of network and database transactions in a CIM system

A Petri-net-based integrated model for the performance analysis of network and database transactions, generated by manufacturing clients for the computer resources, which are acting as the servers, is discussed. A Petri-net-based multifaceted integrated modeling (PNBMIM) approach to investigate the relevant system integration issues between the logical and the physical access of the information in the manufacturing system is described. The PNBMIM approach proposes an integrated conceptual framework for modeling and performance (both structural and behavioral) analysis of data flow and communication flow. This framework should provide some answers to the impact of relative time-scales on the coupling and decoupling of the various levels of a computer integrated manufacturing (CIM) system and identify the time-scales where integration becomes important.<
