How should a company plan the layout of a factory? Design program content steps are?

Lean industrial plant layout planning, must follow the "minimum input to obtain maximum output" principle, through the use of lean thinking to continuously eliminate the concept of waste, in accordance with the rules of the embodiment of the value stream, according to the operation mode of different product categories design plant planning, aimed at making every drop of input are meaningful, every input will produce the maximum benefit as far as possible. The aim is to make every bit of input meaningful and every bit of input will produce the maximum benefit as much as possible. As a result, Booz & Company has concluded that lean plant planning must follow five basic principles, including standard operating procedures, shortened lead times, quality standards, high capacity utilization standards, and high resource utilization standards.

"Lean plant layout planning must be carried out on top of these five principles." A guru introduction said that broadly speaking, lean plant planning includes two parts: plant location site selection and shop floor layout planning.

"At the early stage of planning, the focus is to consider whether it is a general or specialized building, single-story or multi-story, single-span or multi-span, the shape and orientation of the plant, windows, floor, roof height, column spacing of center columns and side columns, and height of the top of the columns, etc." A guru said, and for manufacturing companies, the production workshop in the factory is an important part. And once the equipment and setup of the workshop is planned, its impact is basically long-term.

"If you wait for production to run only to find problems, and then want to adjust will need to spend a lot of financial, material and human resources. That is, why some business owners, know that the layout of their factory floor is unreasonable, but do not go to change the reason. Because they know that this move is less than a few thousand, more than a few hundred thousand." A guru analysis, said Booz summarized the lean plant layout, mainly from the workshop layout planning as well as plant logistics system planning in two aspects.

It is reported that the so-called workshop layout, is to be in accordance with certain principles, rationally determine the workshop within the constituent units (sections, shifts) of the workplace, the mutual location of the equipment, so as to make them an organic whole, the realization of the workshop's specific functions and tasks.

"As the workshop layout determines the direction and rate of logistics of the workshop later, thus structurally limiting the functional potential of the workshop, so the workshop layout is the most important part of the construction of an effective workshop system. The same workshop address, the same personnel, the same equipment and technology, the material in the process in the order of the process has been continuously flowing forward until completion, without too much meandering or backward flow." The functioning of a production system can be vastly different simply because of the way it is laid out, says a certain guru. In the view of a certain guru, efficient shop-floor layout, as one of the most important means of improving the productivity and efficiency of a company, is also an important part of lean manufacturing thinking.

"The essence of workshop layout is the close and organic combination of manufacturing resources (including people, machines and materials) in space and proper connection in time to reduce the material handling workload, minimize the damage of homemade parts and outsourced parts, and save money." Zheng Gongcheng said that in the process of layout design to consider logistics factors, not only can reduce the transportation costs of its process, but also speed up the production process, and ultimately achieve the purpose of improving production capacity and reduce the cost of production of enterprises.

In addition, a guru also said that in the plant planning, companies focus on three aspects to consider: first, the company's 5-10 years of development strategy, the scale; secondly, the company's production of product categories and the use of which mode of operation; and finally, the principle of economy.

"How to maximize the area used by each unit in the production plant, eliminate unnecessary operations and optimize the relationship between operations. For example, arranging operating units with close operational relationships together as much as possible is one of the most effective ways to increase enterprise productivity and reduce energy consumption. Only by shortening the production cycle in terms of time, reducing the footprint in terms of space, and minimizing the retention of materials can inputs be reduced and operating costs lowered." A master said that in the layout design, we should make full use of space and reasonably reserve space for development in order to avoid unnecessary alteration and expansion.
