What is the MES system? 12 Important Questions Answered

 What is MES system?

MES is the execution layer between the planning layer and the on-site automation system. It is mainly responsible for workshop production management and scheduling execution. A well-designed MES system can integrate management functions such as production scheduling, product tracking, quality control, equipment failure analysis, network reporting, etc. on a unified platform. Using a unified database and connecting through the network can be used for the production department, quality inspection department, Process department, logistics department, etc. provide workshop management information services. The system helps companies implement complete closed-loop production by emphasizing the overall optimization of the manufacturing process, and assists companies in establishing an integrated and real-time ERP/MES/SFC information system.




The main functions of the MES system:

It provides flexible and powerful tools for enterprise production managers to monitor and manage the process, ensure the normal operation of production, and control product quality and production costs. Includes the following functions:

Correctly grasp the number of products in the production process and the tracking of defective products to reduce the cost of products in the production process;

Use barcode to track product serial number, improve product after-sales service level;

Timely respond to product quality issues, trace quality history, and improve product governance;

Significantly reduce on-site manual work and improve the productivity of on-site management personnel;

Fully grasp the use of tools and equipment to enable efficient operation of manufacturing resources;

Powerful statistical reports provide real-time, accurate and reliable production data for corporate management decision-making, and improve the company's core competitiveness.


What is the use of MES system?

The MES manufacturing execution system can monitor the entire process from raw materials entering the factory to the finished product, and record the materials and equipment used in the product during the process, the data and results of product testing, and the production time and personnel of each process. After MES system analysis, the production progress, target achievement status, product quality status, and the utilization status of people, machines, and materials can be displayed in real-time through system reports, which makes the production site transparent. The management personnel of the enterprise can see the situation of the production site clearly and clearly through the Internet. The bosses of the headquarters can also use MES to obtain information and plan strategies. Of course, customers far abroad can also care about the progress of their orders and the quality of their products.


What benefits does the MES system bring to the factory?

Optimize the production and manufacturing management mode of the enterprise, strengthen process management and control, and achieve the purpose of refined management;

Strengthen the collaborative office ability of various production departments, improve work efficiency, and reduce production costs;

Improve the timeliness and accuracy of statistical analysis of production data, avoid human interference, and promote enterprise management standardization;

Provide effective and standardized management support for the quality inspection of enterprise products, intermediate products, raw materials, etc.;

Real-time control of information such as planning, scheduling, quality, process, equipment operation, etc., so that relevant departments can find and solve problems in time;

Finally, a standardized production management information platform can be established using the MES system to enable the interconnection and intercommunication of information between the on-site control layer and the management within the enterprise, so as to improve the core competitiveness of the enterprise.

MES manufacturing execution system optimizes manufacturing through results. The traceability function of the production process makes it clear to the company which company provided the raw materials of the product and when, who the recipient is, the parameters to be inspected, the various links in the production, technical parameters, operators, and so on. According to the feedback, solve the problem of enterprise cost or product quality, make timely adjustments, and provide customers with better services in a targeted manner. At the same time, the data of the product production process provides support for management decision-making, so that the problems in the process can be dealt with in a timely manner.


The MES manufacturing execution system optimizes the entire workshop manufacturing process, rather than a single production bottleneck;

The MES manufacturing execution system must provide the function of collecting data in the production process in real time, and make corresponding analysis and processing;

The MES manufacturing execution system needs to interact with the planning layer and the control layer, and realize the full integration of enterprise information through the continuous information flow of the enterprise.

The MES manufacturing execution system is a production management technology and real-time information system that has been rapidly developed in world  in the past 10 years and is oriented to the workshop level. The MES manufacturing execution system can provide users with a fast-responsive, flexible, and refined manufacturing environment, helping companies reduce costs, deliver on time, improve product quality and improve service quality. It is suitable for different industries (home appliances, automobiles, semiconductors, communications, IT, medicine), and can provide good enterprise information management for single mass production and mixed manufacturing enterprises that have both small batch production and mass production of multiple varieties.


Question 1: Is it necessary to go to the MES system?

Answer: The MES system can achieve strict quality management in time and to the greatest extent through real-time collection of on-site product information; on the other hand, the use of the MES system can achieve strict control of the production plan , thereby ensuring the timeliness of the product to the greatest extent Delivery provides guarantees in terms of quality control and production schedule. So it is necessary to go to the MES system.

Question 2: How to use the MES system?

Answer: The production factors are managed through modules such as plan management, workshop management, and semi-finished products management, quality management is carried out through on-site collection of product information and process quality management modules, and parts distribution management through the logistics management module.

Questions 3: What is the relationship between MES system and PDM? What is PDM?

Answer: PDM provides technical details of all parts and components, and provides data support for MES .


Questions 4: What is the relationship between MES system and CAPP? What is CAPP?

Answer: CAPP provides the procedures, working hours, quotas, etc. of self-made parts, and provides data support for MES.

The full form of CAPP is Computer Aided Process Planning, and the Chinese translation is Computer Aided Process Planning. CAPP is a way to add relevant process information to the product design data of a company, such as adding processes and man-hour quotas, to convert it into product manufacturing data. This technology helps process designers complete the design from rough to finished product.

Questions 5 : What is the relationship between MES system and ERP? What is ERP?

Answer: ERP is from the perspective of the whole company and manages the technology, procurement, inventory, production and other information of the whole company. It manages a lot, but it is not detailed or specific.

MES is specifically for workshop site management, such as: which process is in the production of various parts and how much has been completed; whether the equipment such as lathes on the workshop site is in good working condition, whether there are any malfunctions, some of them are broken, and where are they broken, When will it be repaired; in addition, the information on the quality of the on-site parts and components, how many are qualified, how many are unqualified, and which parts are unqualified, etc., are more targeted.

Questions 6: Is it necessary to go to MES after going to ERP?

Answer: Enterprises often face the short time from product design to completion of production, resulting in incomplete or even non-existent BOM. ERP cannot be used without BOM. MES can realize normal management of production plans without BOM.

Question 7: What is the relationship between MES system and BOM? What is BOM?

Answer: BOM is the abbreviation of material detail, which provides data support for MES and is the source of data in the MES system.

Question 8: Without BOM, how can MES obtain data information, etc.?

Answer: Obtain data by maintaining the product knowledge base in the MES and on-site data collection.

Question 9: How to collect product information on site?

Answer: Collect the barcode on the product with the barcode gun to obtain the product order number, plan number, batch number, part number (drawing number), process serial number and other information.

Questions 10: How to control the quality?

Answer: The quality is controlled through the acquisition of this information.

Defination of the essential properties of operating systems

Define the essential properties of the following types of operating sys-tems:  Batch  Interactive  Time sharing  Real time  Network  Parallel  Distributed  Clustered  Handheld ANSWERS: a. Batch processing:-   Jobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at all times through buffering, off-line operation, spooling, and multi-programming. Batch is good for executing large jobs that need little interaction; it can be submitted and picked up later. b. Interactive System:-   This system is composed of many short transactions where the results of the next transaction may be unpredictable. Response time needs to be short (seconds) since the user submits and waits for the result. c. Time sharing:-   This systems uses CPU scheduling and multipro-gramming to provide econ...

What is a Fair lock in multithreading?

  Photo by  João Jesus  from  Pexels In Java, there is a class ReentrantLock that is used for implementing Fair lock. This class accepts optional parameter fairness.  When fairness is set to true, the RenentrantLock will give access to the longest waiting thread.  The most popular use of Fair lock is in avoiding thread starvation.  Since longest waiting threads are always given priority in case of contention, no thread can starve.  The downside of Fair lock is the low throughput of the program.  Since low priority or slow threads are getting locks multiple times, it leads to slower execution of a program. The only exception to a Fair lock is tryLock() method of ReentrantLock.  This method does not honor the value of the fairness parameter.
