A Simple Truth About Capacity Planning - Scheduling
The simple truth about capacity planning is that it is measured in time. This is a fact that many planners ignore. It is very common to find capacity planning or "level-loading" processes that try to balance production using units of product. The result is either inflexible manufacturing – using single model production lines – or ...
