To determine the true capacity of a process or a site, a holistic analysis needs to be conducted. This therefore needs to integrate all Technical, Logistical & Operational elements (and their interconnectivities) within the boundaries of the process or facility into a single capacity analysis. Through this the effect of upstream and downstream elements can be understood and incorporated within the modelling. This integrated model allows for a true bottleneck analysis of the process or site to be conducted.
When referring to a process, the true capacity of the current process can be accurately determined, and this can be used to derive two key outputs:
When related to a site, apart from determining the true capacity of the site, two secondary key concepts are to determine the maximum capacity a site can achieve based on site specific constraints and its sensitivity to change.
Typical capacity analysis dimensions include the following aspects:
