Modelling of a pull-flow production system with dynamic buffer stock control

In modern industrial logistics, efficient production relies on synchronizing raw material supply with real-time demand to minimize waste and improve performance. This paper proposes a modelling approach for production systems based on a pull flow strategy, which controls the replenishment of raw materials in response to real-time demand. The production system is represented in Simulink as a discrete manufacturing unit supported by a buffer stock. A feedback control loop governs the flow of materials from the warehouse to the buffer, using demand-driven trigger points to prevent shortages and maintain stable machine throughput. The objective is to ensure uninterrupted production while optimizing stock levels. Simulation results highlight the effectiveness of the proposed approach in synchronizing supply with consumption, enhancing overall system responsiveness and operational efficiency.
