Production Planning Material Control 20

Production control (PC) is to do production planning, also known as production control, the main purpose is to ensure the production plan and production schedule control. The purpose of material control (MC) is to reduce inventory while ensuring that production is met. To reduce the pressure of funds, the main functions are material planning, requisition, material scheduling, material control (bad material control and normal incoming and outgoing material control), etc.

Production planning and material control are collectively known as PMC, which is the production director, production manager, production planning related personnel, workshop director, material supervisor, purchasing supervisor and related personnel need to master, the PMC production planning and material control course of Vance Management Consulting can help master the skill, help master the concept of production management and lean production, sales planning, production planning, material planning principles, logistics planning and material inventory control, dynamic planning and tracking measures, etc.

The purpose of production planning is to ensure the control of the successful completion of production.

The purpose of material control is to reduce inventory on the premise of ensuring that production is satisfied. Reduce the pressure on funds.

Reduce costs, increase profits, shorten delivery times, and ensure quality.

Generally, enterprises have two economic goals: survival and profit, and all management efficiency work is to seek the maximum achievement rate under these two goals. The purpose of material management is to enable enterprises to meet the needs of the user department in a timely manner, in the right amount, at the right price and with the right quality with the lowest cost and ideal and fast process, so as to reduce losses and maximize the efficiency of materials.

Yongkai proposed that the goal of material management is mainly reflected in the following aspects:

Plan your materials correctly.

Proper inventory management.

Strengthen procurement management.

Take stock and so on.

The so-called material control is material control, (control the state of materials used in production, to meet the needs of supply, circulation and other processes, and to achieve the best suitability and reduction. Material control is also called PMC, that is: PMC:

Production Materials Control.

MC: Material control refers to material control, and its main functions are material planning, requisition, material scheduling, material control (bad material control and normal inbound and outbound material control), etc.

The main responsibilities of the property controller are:

The material analysis makes the company not only do not have a backlog of materials, but also do not stop work and wait for materials.

Two aspects of material control work:

First, the company's sales rely on order production. Second, the company's sales orders are few, and it depends on the market analysis after production. For enterprises that receive orders for production.

First of all, after receiving the order, the sales should send the order to the PC staff of the material control department. and indicate the date of delivery requested. PC staff arrange workshop production (some are arranged by workshop dispatchers, and material control PCs only flyer to reduce inventory).

The quantity scheduled for production is the quantity requested to arrive on the order plus the dynamic inventory quantity minus the physical inventory quantity in the warehouse. The production department schedules according to the quantity to be produced, and hands over the scheduling results to the MC staff of the material control department. The MC clerk then calculates whether the order needs to purchase materials.

The purchase item is on arrival on the day before the production order.

The purpose of material control:

It is necessary to control the procurement of raw materials and other materials, and not to purchase a large number of materials back in the warehouse without production in the near future, resulting in too much inventory in the warehouse, and not to appear that the raw materials for production are still not in place. It is best to achieve the purpose of arriving just right with the right to achieve zero inventory or close to zero inventory. ”

The work content of the material control personnel mainly includes (production management and material control network):

1. Setting of requisition method and stock basis.

2. Analysis, statistics and ** of production materials.

3. Requisition of production materials and conversion of surplus materials.

4. Coordination with production management, procurement and other departments for abnormal feeding.

means of control.

It usually includes the following three points:

l Control the quantity to meet the demand of production volume.

l Control the schedule to meet the needs of the production period.

l Control the difference compensation to meet the needs of write-off and settlement.

The task of material control.

l Control the supply status of materials, ensure adequacy, and reduce material cuts;

l Control the flow state of materials to ensure punctuality and meet the delivery period;

PC production control, mainly to formulate a feasible production plan and supervise the implementation of the production department; MC material control, the demand for various materials required for each process of production, inventory, purchase, and delivery period are controlled.

The PC must be formulated on the basis of doing a good job in the MC, otherwise the production plan cannot be implemented and implemented due to lack of materials or delayed arrival.

The general procedures and processes are: sales receipt order - technical or R&D department (technology, process) review - PMC department (production cycle, capacity, delivery time, etc.) review - PC verification of finished product available inventory to determine production volume - MC calculation of material requirements according to production volume - MC verification of material available inventory to determine requisition quantity - MC purchase materials - purchase under the purchase order and reply to material delivery date - PC comprehensive finished product delivery date, product production cycle, actual production capacity of each process of the production department, Factors such as material delivery date to formulate a production plan and issue it to the production department - the production department of each process picking, production according to the plan and quality inspection - the final process is completed and quality inspection, and the finished product is put into storage - PMC department notifies the sales department that the shipment can be made.

The key elements of PMC control: finished product production volume, material requisition, material delivery time and production cycle.

Scheduling production and requisition materials without taking into account the available finished goods inventory and available materials will result in a backlog of finished goods and materials.

Material requisition takes into account reasonable wear and tear.

The delivery date of materials must be purchased, accurately replied, and checked and tracked many times to ensure that they arrive on schedule.

The production cycle must comprehensively consider the sample trial production, inspection, customer confirmation, the possibility of small orders and orders, the sequence and parallel of mass production processes, the actual production capacity of each process, the shortest production cycle of the product line (from the first process to the last process), the quality inspection cycle of each process, the equipment maintenance cycle and other factors.

The production plan must be specific and feasible, from the monthly plan, the weekly plan to the daily plan, from the product line plan to each process, and closely monitor the production progress.

About the control of production plans and materials.

First of all, you have to make a plan that is highly operational.

There are a lot of factors to consider when it comes to being sensitive:

Material planning: the gross demand of the order, the amount of inventory, the amount in transit, the amount of safety stock, the amount of unissued, mainly according to these things to plan the net demand of the material, can be combined with the economic order batch and the degree of generality of the material, etc., to determine a reasonable requisition quantity, so that the "quantity" of the material plan will come out. As for the time arrangement, it is mainly based on the production plan, that is, when there is a demand for what kind of materials and how much demand.

The main considerations before the production plan are order delivery, customer level, empty clearing process route, workshop capacity, procurement cycle, external processing cycle, production preparation time, abnormal processing time, etc., after formulating the production plan and material plan, it is necessary to verify its operability with the capacity load, and send it to the relevant departments for signature confirmation.

With this standard, it is believed that the control will be in place by confirming, controlling and coordinating at each time control point.
