What Is Production Workflow?

The production process, also known as the process flow or processing flow, refers to the process of sequentially processing from the input of raw materials to the output of the finished product through a certain equipment in the production process. It also refers to the combination of elements in the production process of the product from raw materials to finished products.

Production Process

Basic elements of the production process:

As a complete process, the production process should basically have the following elements: customer, process, input, output, resources,

Basic attributes of the production process:

The basic attributes of the production process are mainly introduced from the scope, scale, classification, classification, and performance of the production process.

Lean production utilizes traditional industrial engineering techniques to eliminate waste and focuses on the entire production process, not just individual or several processes.

(1) Eliminate quality inspection links and rework. If the quality of the product starts from the design of the product until the entire product is manufactured on the assembly line, the quality of each link can be guaranteed 100%, then the phenomenon of quality inspection and rework will naturally become redundant. . Therefore, the idea of "error protection" must be penetrated throughout the production process, that is, quality issues have been taken into account from the design of the product to ensure that each product can only be processed and installed strictly in the correct way. This avoids possible errors in the production process.

(2) Eliminate unnecessary movement of parts. The unreasonable production layout is the root cause of parts moving back and forth. In the workshop organized according to the process specialization, parts often need to be moved in several workshops, which makes the production line long, the production cycle is long, and it takes up a lot of work in process inventory, resulting in high production costs. By changing this unreasonable layout, the equipment required for the production of products is arranged according to the processing order, and as compact as possible, which is conducive to shortening the transportation route, eliminating unnecessary moving of parts, and saving production time.

(3) Eliminate inventory. Treating inventory as a rush to production and sales is like drinking and quenching thirst. Because inventories can hide many problems in production, they can also increase the inertia of workers, and even worse, they take up a lot of money. In lean enterprises, inventory is considered the biggest waste and must be eliminated. A powerful measure to reduce inventory is to change the "batch production, queue supply" into a one-piece-flow. In the single-piece production process, basically only one production part flows between the various processes, and the entire production process always flows with the progress of the single-piece production process. Ideally, there is no work in process inventory between adjacent processes. To achieve the one-piece production process and maintain the fluidity of the production process, the following two points must be achieved:

Synchronization ---- In an uninterrupted continuous production process, each process in the production unit must be balanced, and it takes approximately the same time to complete each operation.

Balance --- Arrange the work plan and staff reasonably to avoid the work load of a process being too high for a while and too low for a while. However, in some cases, a certain amount of WIP inventory must be retained, and this amount depends on the transfer time of two adjacent processes.

Implementing one-piece production processes, synchronizing, and balancing these measures, the goal is to match each operation or set of operations to the production line's one-piece product Tact time. The production time of a single product is the production time required to meet the needs of the user, and it can also be considered as the beat or rhythm of the market. When the production is strictly organized according to Tact time, the inventory of finished products will be reduced to a minimum.
