A pull method in materials planning is a control principle in which material flows and production processes are \u201cpulled\u201d by actual requirements instead of being \u201cpushed\u201d by planned specifications. It is a central element in lean production systems such as the Toyota production system.<\/p>\n

With the pull principle, material is only supplied or produced when there is a specific requirement – e.g. when a downstream process reports a withdrawal. This is in contrast to the push principle, where material is provided in advance on the basis of forecasts or production plans.<\/p>\n

A distinction can be made between two forms of the pull principle: On the one hand, it is used for stocked materials, and on the other for customer-specific materials. The first type is generally understood as the pull principle. Quantities of material are removed from the stocked material, which is located in a \u201csupermarket\u201d, and the removed material quantities are replenished according to a defined rule. This mechanism can take place at all stages of the value chain, from raw material to finished material.<\/p>\n

In principle, however, every delivery to a customer order is based on the pull principle, whether the customer order is used to order stocked items or whether customer-specific production or assembly takes place. In this case, there is a supermarket with customer order-neutral stocks at the logistics decoupling point. Material is taken from these stocks but not delivered directly; instead, it is further processed or assembled for the specific customer order and only then delivered to the customer.<\/p>\n

Production control and scheduling processes that are based on the pull principle include consumption-based scheduling, reorder point control and Kanban. To a certain extent, the CONWIP process and the POLCA process<\/a> also belong to this category.<\/p>\n

The advantages of pull processes are lower stock levels, greater transparency in the material flow, the avoidance of waste and less control effort, provided that demand is stable.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t

Our tip:<\/strong><\/p>\n

It is often claimed that pull processes in materials management do not require demand forecasts, as only what is actually withdrawn is replenished. However, this view is too short-sighted, as the stocks in the supermarkets must be sufficient for the next delivery. A demand forecast is therefore necessary. However, many users are not aware of this, as they set stock levels \u201cfrom experience\u201d and do not determine them using statistical or AI-based forecasts.<\/p>\n

Pull methods are not suitable in all replenishment situations. If demand fluctuates greatly, they are very susceptible to overstocking and\/or delivery reliability. When it comes to complex products or supply chains with frequent material changes, the control effort quickly becomes very high.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
