Production efficiency is an important attribute of manufacturing enterprises. Problems that affect production efficiency should be paid attention to and avoided, and resources should be actively coordinated to improve, so that enterprises can operate in an orderly and orderly manner.
1. Factors Affecting Production Efficiency
1. Frequent changes in product processing technology
The processing technology standard of the product should not change for a period of time. The standard should be simple, convenient and easy to understand. The system that is easy for employees to use is an important factor to maintain product efficiency and quality stability, especially in the form of assembly line operation. What must be done is Dividing a position into several small actions, simple tasks for employees, repeated actions, reducing the probability of mistakes, will improve the performance of the overall level.
2. The quality of the production process is unstable, and rework or repair frequently occurs
The stability of the production system is a necessary condition to ensure efficiency. The preparation means that must be done before starting processing must be achieved. The return caused by unqualified product quality is a very low-level mistake. The low acceptance of employees also affects the overall efficiency. achieved.
3. There are too many urgent orders or temporary orders, and the production plan changes frequently
There are too many temporarily added production orders, which will have varying degrees of impact on "people, machines, materials, and methods."
4. Machine failure in the production workshop, long maintenance time
Equipment failure during production will damage the progress of processing, which in turn affects the overall efficiency of plan implementation. The daily maintenance of equipment is essential, daily inspection, weekly inspection, monthly inspection, and annual inspection equipment should be readily available, paving the way for the overall processing progress.
5. The order only has the delivery date, and the processing start date is not set
6. The purchase material plan and the production plan cannot be coordinated and synchronized
7. The procurement of materials is often delayed and the quality of the procurement is often poor
8. The production department did not conduct a complete capacity analysis
The company's standard production capacity is the yardstick for evaluating its own processing capacity. Normal evaluation of its own product output capacity can play a role in promoting "quality, cost, and delivery time". It can only be counterproductive. If it is too high, it will cause insufficient products, delay delivery, and affect the overall production order plan. If it is too low, it will cause overdue inventory due to excessive processing.
9. The sales department missed an order
2. How to improve workshop production efficiency
1. The basic skills that a sound production and operation system should have: to stabilize the position and ensure efficiency
To improve production efficiency, we must first understand the foundation of production operation management - basic management. Use the 5S approach, combined with the optimization of production and operation processes, to find a solution.
The key is: whether it is a process or a process, it will be easy to manage if they are transparent, visualized, standardized, and stable.
2. Clear goals
The so-called waste at the production site refers to various factors that reduce production efficiency. Through the action plan and on-site diagnosis, use the seven major wastes to establish the real cause of the efficiency loss of production and operation management.
3. Use on-site rapid improvement methods to manage source and flow and improve efficiency
Efficiency is life, time is money. In the fierce market competition, if an enterprise wants to remain invincible, the key lies in "fastness" and "newness". Find ways to improve production efficiency and improve processes quickly, and quickly track problems.
On-site rapid improvement methods:
IE quickly improves four ideas: eliminate, cancel, rearrange or replace, simplify
Five-five method for source and flow management. 5W2H.
4. Let the plan be fully demonstrated, reduce planned losses and improve efficiency
Through the production and sales meeting: ensure the close cooperation between production and sales, so that the quality and production capacity of products can be continuously improved, and the maximum benefit can be obtained with the most reasonable production efficiency.
5. Use a reasonable procurement mechanism to ensure the coexistence and common prosperity of both parties to improve production efficiency
Modern win-win model: assist suppliers, help suppliers reduce costs, improve quality, and speed up product development; establish mutual trust relationships, jointly improve efficiency, and establish long-term partnerships with suppliers.
For different suppliers, it is necessary to do a good job of evaluating and classifying different suppliers. The premise is to establish a useful evaluation mechanism and purchase in proportion.
Give different incentives to suppliers with different results.
6. Material and production schedule control to avoid waiting for waste
After receiving the order, the production management department must mobilize all staff to complete the planned plan with all their strength. Do not change the plan, all relevant departments actively and actively cooperate, actively report the work progress to other units, and jointly complete all plans.
Key points of production management operation:
Managers actively participate in material follow-up and regularly check
Rational use of receiving and issuing materials in warehousing management
quick line change
7. Use performance index improvement method to evaluate enterprises to improve production efficiency
Adopt the lean method, shorten the delivery time, reduce waste, and make the quality, output and efficiency reach a new level.
Metrics:
Calculation of the time from raw material to factory to product shipment
first pass rate
Overall Equipment Efficiency
Production schedule compliance rate
8. Implement the leadership policy through departmental management performance, improve production efficiency, and effectively achieve business benefits
·Daily key item management is to make the strength of the department/workshop give full play to produce good performance; ·If there is an abnormality, it can be found and dealt with effectively, and the actual management should be done well.
9. Use reasonable operating performance to motivate morale and improve efficiency
Rationalization of the incentive system:
performance bonus
performance indicators
10. Utilize the rules of rapid changes in production and operation to allow enterprises to improve production efficiency
Responding to changes in the situation in a timely manner, quickly revising the plan, communicating quickly and accurately, and the flexibility of production plan preparation and revision are the most important conditions.
