Push system: what it is, features, advantages, disadvantages, examples

In a push system, production is done in advance

What is the push system?

He push system It is a manufacturing system in which production is prepared in advance, based on a projected production plan, where information flows from management to the market.

It is a production planning and control system in which products are moved forward through production by the previous step in the process.

It involves forecasting inventory needs to meet customer demand. Firms must predict which products customers will buy, as well as determine how many products will be purchased.

The company will manufacture enough products to meet the anticipated demand to be able to ship these products to the consumer.

In a push system, the company forecasts demand, prepares a production schedule, and then orders inputs to begin the production process. The result is a buildup of inventory.

It is designed so that the company is always ready to sell and deliver to customers. Inventory is “pushed” to the customer.

Push system features

– A production level is established based on historical customer order patterns. With a push-based supply chain, products are pushed through the channel, from the production side to the customer.

– Push production environments tend to be characterized by long delivery times and/or unwanted inventory situations.

– Process large batches of items, based on forecast demand, then move them to the next production process or storage.

– It is based on demand forecasts. However, the forecast may not always be accurate, so you can end up with excess inventory, especially when delivery times change.

Advantages

– An advantage of the push system is that the company will always be fairly certain that it has enough products on hand to fill customer orders, thus ensuring that customer demand for products is met.

– Businesses and their retailers have the advantage of predictability in their supply chain. This sense of predictability allows retailers to plan ahead for how to store product and organize merchandise.

– It is recommended for products with low uncertainty in demand. This is because the forecast will provide a good indication of what to produce and hold in inventory.

– It is also suggested for products with high importance in economies of scale, to reduce costs.

Disadvantages

– The downside of the push system is that forecasts are often inaccurate, as sales can be unpredictable and vary from year to year. This can lead to an under or over supply.

– If you underestimate the demand for products and don’t react quickly, you can lose business and alienate customers.

– A push-based supply chain takes longer to respond to changes in demand. This can result in excess stock, bottlenecks and delays, unacceptable service levels, and product obsolescence.

– Another problem with push systems is that too much product can be left in inventory.

– This increases the company’s costs for the storage of these goods. In addition, there is a possibility that these products may have to be discarded.

Examples of push system

An example of a push system is the Material Requirements Planning (MRP) system. The MRP combines the calculations for both financial planning, as well as for operations and logistics.

It is a computer-based information system that controls both the programming and the orders to be placed. Its purpose is to ensure that raw materials and materials necessary for production are available when needed.

The classic stock system is another push system. In this system there is no limit to the number of jobs in progress. This is because backorders can increase inventory beyond the base level.

case seat belts

In a push system, the manufacturer estimates the demand for replacement seat belts. Then create a plan to manufacture those belts over a period of time.

Once the seat belts begin to roll off the production line, they are packaged in boxes (100 seat belts per box), and shipped to distributors in the order of priority where the highest demand was anticipated to be.

These dealers ship the seat belts to the car dealers, who already have them in stock, so that when a customer asks for a replacement seat belt, it can be delivered in a short period of time and the customer is satisfied.

The problem with this system is that it creates inventories throughout the system: at the manufacturer, at the dealer, and at the car dealer. This can cause problems.

For example, suppose a fault was identified in the seat belts, making them unsafe. They would all have to be discarded, and the seat belts stored at all points in the system would have to be removed.

It’s better to have as little inventory as possible in the system, but still keep customers happy.

candy factory

A candy factory produces candy without customer orders. It is an item that is always sold.

Sanitary napkin and tampon company

The factories of this type of feminine devices elaborate their products in very large quantities, to supply and satisfy the hygienic needs of the female population. Therefore, even if there is excess inventory, it is not lost, because it will eventually be sold.
