Such systems can be classified as pull and push systems (Spearman et al. 1990 [1]). In a push system, the production order is scheduled, and the material is pushed into the production line. In a pull system, the start of each product assembly process is triggered by the completion of another at the end of production line. This pull-variant is ...
The original meaning of push and pull, as used in operations management, logistics and supply chain management. In the pull system production orders begin upon inventory reaching a certain level, while on the push system production begins based on demand (forecasted or actual demand). The CONWIP is a hybrid between a pure push and pure pull system.
The central tenet to DFT is the primacy of customer demand in daily execution of the operation. According to Aberdeen Group, "Demand driven manufacturing involves a synchronized, closed loop between customer orders, production scheduling, and manufacturing execution; all while simultaneously coordinating the flow of materials across the supply chain."
Human migration#Push and Pull, factors pushing migrants out from home, or pulling them toward a new host; Push–pull agricultural pest management, in farming, an intercropping strategy for controlling agricultural pests. Push–pull strategy, in logistics, supply chain management and marketing; Push–pull workout, a type of weight-lifting routine
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Suffering a glut in green cars, sales and marketing developed a program to sell the excess inventory. While successful in generating the desired market pull, manufacturing did not know about the promotional plans. Instead, they read the increase in sales as an indication of growing demand for green cars and ramped up production. [3]
The system diagram for representing control loops is a Piping and instrumentation diagram. Commonly used control systems include programmable logic controller (PLC), Distributed Control System (DCS) or SCADA. Example of level control system of a continuous stirred-tank reactor. The flow control into the tank would be cascaded off the level control.
Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
