Bullwhip effect

The bullwhip effect describes coordination and communication problems in multi-stage supply chains - usually in so-called fragmented supply chains. It can be localized thanks to fluctuations in production planning and logistics planning (price fluctuations and bundled orders/delivery bottlenecks), but is intensified by the increase in production stages. In other words, the whip effect occurs when…

Inventory management, stock and stock reconciliation in intralogistics

Inventory management stands for the seamless digital recording of all inventory movements in intralogistics in order to obtain reliable information about the storage location (where?), quantity (how much?) and quality (what?) of all products at all times. The statements are collected from information from the host system and the warehouse management system (WMS), merged and compared with each…

Transhipping rate

(abbr. UR; Transhipping rate) indicates how often the average stock in a warehouse is turned over per year, i.e. UR = annual sales volume/average stock (in terms of value or quantity). See also Inventory turnover. Source: logipedia / Fraunhofer IML

Production planning and control system

A production planning and control system (PPC system) comprises information-processing systems for production planning and control. PPC systems can be categorized according to the control principle as follows, for example Input-oriented control Control according to planned average process sequences (Material Resource Planning I) Control according to priority rules, cumulative quantity…

Production requirements planning

Production requirements planning comprises all planning measures for the production of goods or the provision of a service. It includes the so-called gross and net determination of secondary requirements (required materials without or with the inclusion of warehouse stocks), the allocation of the resulting procurements (external production or in-house production), throughput scheduling…

Neutral goods

Neutral goods are goods without final packaging. In the case of identical articles with different final packaging, the article only receives its final packaging after receipt of the order in order to reduce the necessary stock levels. Source: logipedia / Fraunhofer IML

Net demand

Net demand is the order quantity of an item less the available stock and open goods receipts. Source: logipedia / Fraunhofer IML

Minimum stock

Minimum stock is the minimum stock level required to maintain delivery readiness. The amount of M. is determined on an item-specific basis and is then a mathematical control variable for triggering replenishment orders or ordering processes. Replenishment Source: logipedia / Fraunhofer IML

Three-step stock management

Three-step stock management (three-step inventory management): Several single-item inventory units that are located in a common storage container are combined to form a load carrier (step 1). Loading aids and stock units can in turn be located on a common load carrier (level 2). This load carrier is then managed as a load unit (level 3). If such load units are supported, each stored unit is…
