What is production and Material Control (PMC)

PMC control goals include quality control objectives, progress control goals, investment control goals, and security control goals.
What is PMC? PMC is the English "Portable Media Center

● What is production and Material Control (PMC )?
PMC stands for the product material control abbreviation, meaning production and Material Control. Generally, it is divided into two parts:
PC: production control or production control (commonly known as TV companies or Japanese companies ). Its main function is to control production planning and production progress.
MC: Material Control (commonly known as material control). Its main functions are material planning, procurement requisition, material scheduling, and material control (bad material control and positive
Control of incoming and outgoing materials.
● What are the main aspects of capacity analysis?
The capacity analysis mainly targets the following aspects:
1. What kind of model is used and the manufacturing process of this model.
2. Machines Used in the process (device load capacity ).
3. Total Standard Time of the product, standard time of each process (HR capability ).
4. preparation lead time of materials.
5. Size of production lines and warehouses (site load capacity ).
● What principles should we pay attention to during production scheduling?
The following principles should be noted in the production plan schedule:
1. Delivery date sequence principle: the shorter the delivery time, the more urgent the delivery time, the more arrangements should be made at the earliest time.
2. Customer classification principle: the customer has key customers. Generally, the more important the customer is, the more important the scheduling should be. If yes
The company classifies customers according to the sales amount according to the ABC method. Class A customers should be given the highest priority, and Class B customers should be given the second priority. Class C.
3. Principle of balance of production capacity: The production of each production line should be smooth, the production speed of the semi-finished production line should be the same as that of the finished production line, and the machine should be negative
Load should be considered, there is no production bottleneck, there is a shutdown waiting event.
4. process flow principle: the longer the manufacturing time for products with more processes, the more attention should be paid to them.
● What is the cause of poor PMC management?
PMC's planning, control, and communication and coordination capabilities are poor, which may cause the following problems:
1. Regular shutdown: due to the lack of planning for production or the lack of material planning, the material progress is often unable to keep up with, resulting in frequent
Suspension and waiting
2. a full meal in production: because of frequent shutdown and waiting for materials, the delivery time will naturally become short and the production time is insufficient,
Only by working overtime to catch up with the goods, sometimes starved to death.
3. inaccurate material plans or poor material control. semi-finished products or raw materials cannot be linked up. It should not be a big one.
Stack, resulting in a large number of accumulated materials and semi-finished products in the warehouse, and the production is naturally not smooth.
4. the production schedule only plays a role in form. The production plan is out of touch with the actual production plan. The plan is one set, and the production plan is one set.
The plan does not work at all, and it takes a form.
5. Inaccurate sales forecasts or inaccurate analysis of production capacity, no reasonable arrangement of production capacity, no leave of room for production planning
Poor mobility, frequent changes to production plans, and a large number of urgent orders make the execution of production plans a bubble.
6. Poor coordination of planning, production and material schedule, affecting the delivery date and reducing the company's reputation.
7. Frequent production disorder and uncontrolled quality, resulting in frequent rework and frequent rework that affect the execution of production plans, resulting in evil
Loop.
