Production Management of Small Batch and Variety

Production Management of Small Batch and Variety

The production mode of small batch and multi-variety is to adapt to the changing market, according to market demand, order, quality, quantity and punctual production. In the market economy, consumers tend to diversify their hobbies and pursue high-level, unique and popular commodities different from others. New products emerge in an endless stream. In order to expand market share, enterprises must adapt to this change in the market. The diversification of enterprise products has become an inevitable trend. Of course, we should see that the diversification of products and the emergence of new products will also lead to the elimination of some products before they are out of date and still have usable value. It is a great waste of social resources, and this phenomenon should arouse people's attention. Its goal is to shorten the delivery time and reduce the inventory of the production system.

1.Improve adaptability to changing demand

Small batch, single piece transmission

Multi-skilled employees

Internal Quality Assurance System of Processes

Universalization of Equipment and Fixtures

2.To expose manufacturing problems and their weaknesses

Quality failure

Equipment failure

Workload imbalance

Transfer time

3.Eliminate waste caused by improper production management and reduce production management costs

Material waiting due to improper production management

Unnecessary type change due to improper production management

Increase in indirect operations due to improper production management

4. Improve the adaptability of manufacturing to short delivery time

Eliminating Stagnation ( Information of it)

Reduce the number of intermediate products in process

Synchronization

Characteristics of small batch and multi-variety

1. Multivariate Parallel

Because the products of many enterprises are aimed at customer configuration, different products have different needs, and the resources of enterprises are in many varieties.

2. Resource Sharing

Every task in the production process needs resources, but the resources available in the actual process are very limited. For example, equipment conflicts are often encountered in the production process, which is caused by project resource sharing. Therefore, limited resources must be appropriately allocated to meet project needs.

3. Uncertainty of Order Result and Production Cycle

Because the demand of customers is unstable, and the planned nodes are inconsistent with the complete cycle of human, machine, material, method, loop, etc., the production cycle is often uncertain. The project with insufficient cycle needs more resources, which increases the difficulty of production control.

4. Variable material requirements lead to serious procurement delays

Due to the insertion or change of the order, it is difficult for external processing and procurement to reflect the order delivery time. Because of small batches and single source of goods, the supply risk is very high.

Difficulties in small batches and multi-varieties

1. Dynamic process path planning and virtual unit line deployment: emergency plug-in, equipment failure, and bottleneck drift.
