Even without demand variability, production schedules cannot be executed. Any planner with shop floor experience knows that demand variability is not the only source of distortion. Suppliers, employees, and equipment can also let you down. Usually, this type of variation is known as operational variability. Below is a chart that shows the BOM and Routings … Read more
Before MRP, the most popular approach to inventory management was Order Point, where each point is independent. Yet the more complex an operational environment becomes — thanks to a broader SKU list or changes to assortment and demand — the more likely you are to see bimodal inventory distribution, when too little of the right … Read more
