More control thanks to less planning


Not too long ago I spoke with a couple of planners at a manufacturing company. With a certain despair they confided that the planning they created had to be changed continuously. It was certainly no exception that the planning was changed at least 50 times between creation and execution. Even next day’s planning was subject to frequent changes.

Managing these short life cycle items is complicated. If these items are purchased in Asia, only one purchasing decision can be made, often long...

EOQ or EPEI? Which is better?


Most production companies acknowledge the importance of batch sizes. They realize that batch sizes directly contribute to inventory levels, costs, working capital and even capacity. A one-size-fits-all solution, for instance to give every item a batch size of a month, is without a doubt not optimal. There is room for optimization. There are two...
