Choice of Control Interval for Controlling Assembly Processes

Summary

Many industrial products are produced by continuous processes. Time series analysis and control theory have been widely applied to such processes. There are also many industrial products that are produced by assembly processes. In those processes, time series analysis and control theory are usually not required. However, there exist assembly processes that do need time series analysis for effective process control. Problems are discussed when time-series analysis methodology is applied to specific assembly processes for effective process control, especially if the number of products is high. Influential factors like the control interval and dead time of the process under consideration are considered.
