PushSysteme

PushSysteme refers to push-based systems used in production planning, logistics, and information distribution. In a push system, decisions and work packets are created in advance and then pushed downstream to subsequent processes or recipients based on forecasts, schedules, or pre-defined rules.

Origin and concept: In manufacturing and inventory management, push systems arise from master planning where forecasted demand drives production and replenishment. They contrast with pull systems, where activities are initiated in response to actual demand, such as kanban or just-in-time approaches. The term emphasizes the direction of work flow from upstream decision points toward downstream stages.

Characteristics: Key features include forecast dependence, longer lead times, and the use of buffers or safety stock to absorb variability. Efficiency is often pursued through high utilization of capacity and standardized processes, but rigidity and inventory risk can increase if forecasts are inaccurate. Coordination typically relies on centralized scheduling and bill-of-material structures to determine what to produce and when.

Applications: Classic push systems are associated with materials requirements planning (MRP) in factories, where production and procurement are planned around a master schedule. In information technology and networks, a push model describes servers that push updates, notifications, or content to clients rather than requiring clients to request them. PushSysteme can thus span manufacturing logistics, software distribution, and content delivery.

Limitations and trade-offs: Push systems can reduce response time and simplify planning when demand is stable, but they are vulnerable to demand fluctuations, forecasting errors, and increased inventory costs. Hybrid approaches that blend push planning with pull execution aim to improve responsiveness and reduce overproduction.
