आंगन के होर्डिंग दृश्य परिचय और बायोशी के लिए अनुमति देते हैं

प्रत्येक समुदाय के लिए विज्ञापनों के विनिर्देश अलग-अलग हैं, और न तो उद्योग और वाणिज्य और न ही शहरी प्रबंधन ने नियम बनाए हैं। विशिष्टता घर की बाहरी संरचना पर निर्भर करती है।

In the production operation, the billboard has two functions: instructing the production process to manufacture the product, and instructing the material operator to carry the product. The former is called production billboards (or manufacturing billboards), and the latter is called pickup billboards (or pick-up billboards). The production billboard informs the upstream process of the type and quantity of products required by the downstream process. In the simplest case, for example, the upstream process prepares a production billboard corresponding to "a box of parts" in advance, and puts it in the inventory supermarket at the same time as a box of parts. When a box of parts is removed, the manufacturing billboard is used to initiate production. Some signal billboards are triangular in shape, so they are also called triangular billboards.

Pickup billboards instruct parts to be transported to downstream processes. There are usually two forms: internal billboards and vendor billboards. At first, in the Toyota City metropolitan area, both forms were widely used, but when lean manufacturing became widespread, those suppliers farther away from the factory switched to electronic forms of billboards. To create a pull system, both production and extraction billboards must be used: in the downstream process, when the operator removes the first product from the tote, he takes a pickup billboard and places it on a nearby billboard in the box. When the mover returns to the inventory supermarket upstream of the value stream, the pick-up billboard is placed in another billboard box, instructing the upstream process to produce one more box of parts. Only in the case of "no billboard, no production, or product handling" is a real pull system.
