Determination of extended availability and productivity for assembly systems using existing data base

Reliable information about the operational availability of assembly or production systems is of great importance for the users of complex production facilities, especially when such facilities operate at their capacity limit. Nowadays, in most cases, the availability of assembly systems is monitored and evaluated using collected status data. This paper presents a new approach for permanent productivity determination of assembly systems based on the usage of in-process acquired product data. This approach is especially applicable for manufacturing systems that produce goods for which complete product traceability is required.
