How to implement MES system in the enterprise

first, why do we need MES solution

MES solution of manufacturing system plays the following roles:

1) we can see the manufacturing site transparently

2) we can formulate manufacturing engineering plan

3) we can issue work instructions in real time according to changes in the manufacturing site

4) we can predict the delivery date, MES solutions that can help delay the delivery date (ask customers for understanding or external assistance, and prevent delivery date delay through overtime planning) are necessary for them to improve the competitiveness of manufacturing enterprises

second, what functions does MES perform

according to the international MES association established in the early 1990s. MES uses real-time data on site to provide information about production activities that can optimize the ordering of products to the completion of production. By reducing worthless activities, effective plant operations are possible and changes can be made quickly. Therefore, MES can not only improve the asset turnover rate, total income, working capital, but also improve the recovery rate of operating assets by providing important information for production activities through the enterprise and supply chain

1) get what kind of product from ERP (Enterprise Resource Management) system and how much it needs to be produced (what to build)

2) when it needs to be produced there

3) give instructions to automation equipment or field workers

4) get work results (what was build) and engineering status (operation status) from the site

5) finally report the production results to the SAP system and other functions

further detailed functions are as follows:

- scheduling of detailed operations considering equipment load

- operation priority and dispatching of each work object

reconstruction according to the actual update of work and schedule

collection of production information (work object, actual production situation, equipment status, etc.)

equipment/operator management (equipment mobility, operator proximity, time management and other functions)

Quality Management (spc/sqc, testing engineering management, laboratory/test room information management)

performance analysis (equipment mobility), cycle time, productivity, planned/actual difference analysis

III The purpose of introducing MES

Electrical/electronic assembly industry: to complete the asset management and quality improvement of products and the corresponding delivery time. MES has two parts: monitoring/control (MC) layer and planning/simulation (PS) layer. MC layer is mainly responsible for equipment monitoring, quality information collection, and order tracking Traceability ability, etc. PS layer is responsible for the agreement of rapid delivery (ctp: capable to promise), the establishment of the final schedule, progress/load management, mastering the expected problems and the ability to support the establishment of response plans. MES acts as a bridge between the manufacturing site and the computer system. MES is also widely used in manufacturing

mes (manufacturing to avoid loose parts in the process of material experiments) is an information system that optimizes all production activities from the ordering of products to the adoption of Oxygen Consumption Calorimeter to determine the release rate of heat and visible smoke of materials and products. ASTM e1354 ⑵ 003 is a standard experimental method for the completion of products. This is to use real-time data to "guide" all activities of all plants, start "start", get "response" and report. Focus on the rapid response to state changes and the reduction of worthless activities, which will bring the efficiency of the internal and production plans of the factory. MES will bring the efficiency of the enterprise's assets (return on operational assets), the correct delivery date, inventory cycle, total profit, working capital, etc. this can also provide the enterprise with mission critical information about the production activities through the supply chain. MES is widely used as the main processing machine of recycled plastic granulator, which will have a broad customer base in the automotive, semiconductor, electronics, food processing, pharmaceutical, medical devices, fabrics, and other manufacturing industries. Schedule management Maintenance management, quality, time, attendance rate and other factors enter all manufacturing industries within the scope of MES

mes refers to resource allocation and status, dispatching production units, data collection/acquisition, quality management, performance analysis, work/detailed schedule management, document management, process management, labor management and product tracking All kinds of information can be standardized. Most of the upper end of the computer system can only issue a simple "operation instruction" command. Report the results to the computer system after completing the operation at the manufacturing site. In this way, the intermediate process of achieving the reported results from the job instructions can not be tracked/monitored/controlled at all. Therefore, MES is needed to act as a bridge between the manufacturing site and the computer system. MES provides functions such as the increase of original price/quality decline, factor tracking and monitoring/control that are not included in the computer system. The database management of WIP, production assets, details/status of equipment held, and other information can be standardized based on these. MES carefully looks at the planned information monitoring and control, equipment control and monitoring, but the economic cost problem, quality management, tracking and control, the collection of performance information, warehouse operation management, inventory management, asset investment management, human management, official management, and the joint management of all information that can occur on site. MES has 11 functions:

1, resource allocation and status

machinery, tools, worker proficiency, assets and documents, etc. can be used for resource management of other workers. The function of resource allocation and status management is to provide a detailed history of resources, provide the status of equipment in real time, and confirm whether the equipment is properly set. Such resource management includes appointment and allocation in line with the objectives of the work schedule

2, operation/detail scheduling

the function of operation and detailed schedule management is to provide a sequence based on the coherent scheme, priority, attributes and characteristics of the production unit to minimize the work of setup when there is an appropriate sequence. Daily management is limited. In order to master the corresponding scheme of repetition/juxtaposition of detailed calculation of equipment loading and moving type at the right time

3, dispatching production units

for job forms such as batch, lot and work order, manage the process of production units. The distribution information is provided according to the real-time changing sequence of operations performed according to the events that occur on site. The following reprocessing plan is related to buffer management and the control ability of all starting points

4, document control

document management functions are operation instructions, prescriptions, drawings, standard operation steps, some procedures, preparation records, requirements of technical changes, and conversations between teams. And what has been planned and made up. The ability of these information, and the control of the record form managed together with the production unit. The document management function provides operators with data or prescriptions for equipment control, so that the operation instructions can reach the operation site. It also includes environmental control and combination and improvement, safety regulations, several correct operation steps, including ISO and other information

5, data collection/acquisition

the data collection function provides records and morphological data related to popular production units and i/f connections for internal production. The above data is collected manually at the production site or automatically from the equipment

6, labor management

the labor management function provides everyone's status by division. Based on time comparison, attendance report, firm tracking, and behavior based costs, including indirect behavior tracking capabilities such as asset and tool preparation. The above functions interact with the allocation of resources to determine the best allocation

7, process control

plan management is to monitor production and provide discussion and decision support for operators who are working upward for ongoing operations, or automatic modification. Such behavior focuses on the machinery and equipment that work internally or from one role to the next, and plans to track, monitor, control, and internally. Externally, it includes the alarm management of plan changes to let the operator and everyone know the allowable error range. It is possible to collect data by providing i/f between intelligent devices and MES

8, maintenance management

instruction and tracking of maintenance behavior of equipment and tools to improve production and schedule management capabilities. Maintain the history of past events in order to help new problems

9, production tracking and history, (product tracking and Genetics)

you can see the location of the job and where the job is completed, the status information is who is working, the supplier's assets, lot Association serial number, current production conditions, alarm status, re operation followed by other matters related to production, and the on-line tracking function generates historical records that give the tracking ability of each use method and factor of the final product

10, performance analysis

the function of performance analysis provides the actual job operation results by dividing into units through the comparison of past records and expected results. The execution analysis results include the test values of resource utilization, resource availability, production unit cycle, schedule compliance, and standard compliance. Pc/sqc can be included. Concretize the information collected from many different functions of the test operation factor. Such results should be prepared in the form of reports or can provide current evaluation of implementation on-line. (end)
