What is pull production and what is pull production? What is push type production

Pull production is to process as many products as needed in the latter operation, and require the previous operation to manufacture exactly the parts needed.

Pull-based production is one of the two pillars of Toyota's production model, "just in time". This is also a production method that Naichi Ohno borrowed from the American supermarket sales method with his superior imagination.

Compared with the push production in the past, the former operation produces parts and "pushes" them to the next operation for processing, and in the pull production, the latter operation processes as many products as needed, and the previous operation is required to manufacture the parts that are exactly needed.

The counterpart to pull production is push production. In push-forward production, each process produces according to the production plan, to the best of its ability, and completes the production task as quickly as possible, regardless of whether the next process is needed at that time. The traditional production system is generally push-type production, which will cause the accumulation of items.

Of course not. Pull production is a term of lean production management, which simply refers to a production operation management method that takes the next process as the customer and takes the customer's needs as the goal in production management.

Summary. Pull production: The latter operation processes as many products as needed, and requires the previous operation to manufacture exactly the parts needed.

Push production: the upper process does not need to be responsible for the next process, and the product can be delivered to the latter process according to the plan after the product is produced.

What is Pull Production? What is push-type production

Hello, I am a professional education services teacher and it is a pleasure to be able to serve you. I have already understood your questions, you don't need to worry, I will inquire and answer your questions immediately! Please wait a minute!

Pull production: the latter operation needs to process as many products as needed, and the previous operation is required to manufacture the parts that are just needed to push production: the upper process does not need to be responsible for the next process, and the product can be delivered to the latter process according to the plan after the product is produced.

The "Hello Water Spider" operation is one of the main means to achieve pull-type production. How to implement the "water spider" operation and effectively achieve pull production? What are the advanced methods and successful experiences that can be learned from the implementation of the "water spider" operation?

The stones of other mountains can be used to attack jade! Although different industries or enterprises have different treatment methods when implementing water spider operations, everything is the same! Let's summarize some methods and processes from practical experience for your reference!

The "water spider" operation is one of the main means to achieve pull-type production. There are three main stages of implementation of water spider operation. First of all, prepare for the water spider operation; secondly, the correct implementation of water spider operations; Thirdly, the water spider operation is continuously tracked and improved in the later stage.

About the preliminary preparation of the water spider. One is to confirm the range of water spiders; the second is to establish a water spider project team; the third is to collect relevant data; Fourth, do a good job in the assessment of differences; Fifth, the division of labor among project members.

Pull-type production method: It is the latter operation that processes as many products as needed, and requires the previous operation to manufacture exactly the parts needed.

Push-type production mode: It means that according to the calculation logic of MRP, each department is produced in accordance with the production plan specified by the company. The upper process does not need to be responsible for the next process, and the product can be delivered to the post-process according to the plan after the product is produced, which is called push-type production.

The demand-pull production mode is guided by lean thinking, but it is based on the reality of state-owned enterprises, allowing the establishment of a small amount of safe inventory and work-in-process reserves, and the quality control standard is the 3 sigma standard.

Demand-driven production is the initial stage of lean production, and it is the only way for domestic automobile manufacturing enterprises to implement lean production by promoting the continuous improvement of all aspects of the enterprise to achieve the goal of lean production through demand-driven production.

1. The essence of the two is different:

1. The essence of push-type production: push-type production refers to the production plan of each department in accordance with the company's production plan according to the calculation logic of MRP.

2. The essence of pull-type production: pull-type production is one of the two pillars of Toyota's production model, "just in time" to achieve the technical bearing.

Second, the precautions for the two are different:

Considerations for push-type production:

The push-type production method cannot meet the requirements of "just-in-time" production. In order to ensure that all products are delivered on time and on time, it is necessary to calculate the lead times of all products and the parts that are disassembled in order to be completely accurate.

Precautions for pull-type production:

Efforts should be made to achieve balanced production, and balanced production is the premise of pull-type production. Equilibrium is not only the quantity, but also the total balancing of variety, man-hours, and equipment load. Equipment and tooling are always in good condition, materials and blanks are on time, and workers' technical peace and attendance are all important conditions.

3. The nature of the two is different:

2. The nature of pull production: compared with the push production in the past, the previous operation will produce parts and "push" the latter operation to process, in the pull production, it is the latter operation that processes as many products as needed, and requires the previous operation to manufacture the parts that are just needed.

The push-through approach refers to the planned manufacture of parts on each production floor and at each work site. The parts that will be machined. It is sent to the subsequent workshop and the next process, and the completion information is fed back to the planning department.

The pull method refers to starting from the product assembly, and each process and each workshop is issued to the previous process and workshop as needed. Work instructions, the previous process and the workshop produce according to these instructions.

Push type and pull type are two different types of job management. In the push mode, each process work center manufactures the workpiece as planned, regardless of whether the subsequent process work center needs it at that time. The pull system, starting from the order on behalf of customer demand, according to the market demand to develop the main production plan and the first sequence plan, starting from the product allocation, each work center according to the needs of the parts at that time, put forward the requirements of the previous process, issue work instructions, the front process center is completely in accordance with these instructions for production.

In this way, the reverse process sequence "pulls" the front work center step by step, until it is "pulled" to the first factory or cooperative plant.

Push-forward approach: a planning department plans in advance according to market demand, and the flow of materials and information is separated.

One way is to calculate the demand for each part and the production lead time of each production stage according to the market demand and parts by a planning department, determine the output plan of each part, and issue production and order instructions according to the plan. Each workplace, each production workshop and each production stage manufactures parts according to the plan, feeds back the actual completion to the planning department, and sends the processed parts to the next process and the downstream production workshop, regardless of whether the latter process and the downstream production workshop need it at that time. The material flow and the information flow are separated.

This is called the push-forward method. A production system that implements a push-type approach is called a push-through system.

Another way is to start from the market demand, and the product assembly is driven by the market demand information, and then the parts processing is driven by the product assembly. Each process, each workshop and each production stage puts forward requirements for the previous process, the upstream workshop and the previous production stage according to the needs of the time, and issues work instructions, and the upstream process, workshop and production stage are produced in full accordance with these instructions. Material flow and information flow are combined.

This is called the towed method. Production systems that implement a towed approach are called towed systems. Toyota's production system is a traction system.

The towed type is the pull type.
