Electronics assembly industry enterprise demand for MES system is determined by the following aspects：
• Industry characteristics
• Their own management needs
• Customer requirements
• Laws and regulations

Industry characteristics and laws and regulations determined by the needs of the universal common, their own management needs and requirements of enterprise customers demand will be determined according to the actual conditions vary in different.

1、Industry characteristics

Electronics assembly industry due to the complexity of the supply chain enterprises need to have MES system：
• Help enterprises to improve the ability of OTD；
• To work with enterprise ERP system integration, help enterprises to improve management and control of logistics.

Product companies need to determine the characteristics of the system：
• For products, semi-finished products to have basic information about the overall management and favorable statistical inquiry；
• Customized products can correspond to production management, be able to customize the product for flexible selection of standard components and definitions；
• Can clearly manage and semi-finished products to the relationship, and in the production of finished products included in the arrangements sufficient demand for semi-finished products and production time.

The industry in terms of the characteristics of enterprise requirements planning system：
• Users can provide a reference for planning；
• Be able to integrate with ERP systems, from the enterprise to form the corresponding master production schedule automatic decomposition scheme；
• Provide convenient scheduling and adjustment tool；
• Implementation of the plan to change the situation to conduct a comprehensive comparison of records；
• Timely feedback to the progress and implementation of the plan differences.

Manufacturing process is characterized by a system that can lead to customer needs：
• Timely manner to the plan and the plan is passed to the manufacturing site change；
• Collecting the manufacturing process, process and result information；
• Guidance throughout the product processes；
• Increase production line in response to various changes and the feedback speed；
• Engineers needed to provide help to improve the manufacturing process a variety of information；
• Providing real-time production management personnel to quickly understand the status of the channel；
• Achieve WIP batch tracking and management；
• Assist production line managers and reasonable arrangements for batch jobs；
• Timely provision of adequate information to workers as operating instructions；
• Work by guaranteeing the right way to avoid or prevent problems.

From the cost point of view to consider the user needs the system：
•Capable of manufacturing process material consumption, working hours, staff utilization, equipment utilization information for real-time recording;
• The ability to integrate and summarize the information recorded by calculating the results are compared with the expected, pointing out the differences.

2、Their own management needs

Production of increasing complexity, for the management requirements are increasing, resulting in a lack of senior management, while managers a lot of work time spent in information gathering, analysis and handling of many everyday affairs can really be used exceptions to solve the problem, the problem of time thinking decision-making is limited. Engineers busy routine production management, back and forth between the production line at the publishing process, solving routine problems, collection forms, statistical data. Operator to obtain engineering, process, product change information is often delayed, equipment, tools after the problem occurs it takes too much time to notify the engineer, waiting to solve the problem. These phenomena greatly reduced staff productivity, making employees mired in tedious and time-consuming conventional process. Therefore, the enterprise requirements from the perspective of their own management system to：

•Management practices to reduce transaction processing time；
• Improve the speed and accuracy of information transmission；
• Flexibility to provide a variety of statistical reports to support business decisions；
• Ensure that the system for a long period of time to adapt to changes in business management；
• Flexible, with the expansion of business scale, the flexibility to add the corresponding functions and maintain good continuity.

3、Customer requirements

Electronics assembly industry in the 2-4 class enterprises are superior enterprise suppliers. As the top companies in the face of repeated questions as components, design issues product recall due after the events of the enterprises themselves and their suppliers raised more stringent requirements. This requires the system to：

• Provide comprehensive information on the manufacturing process of the material；
• Providing quality information for all products；
• Provide enterprise customers remote viewing channel customer product production status；
• Provide corporate clients remotely adjust customer product manufacturing processes and process of the channel；
• Problems arise when a product is to help enterprises accurately track the source of the problem as well as the source of all the products involved in the

4、Laws and regulations

EU environmental protection order has been implemented, while China's "Electronic Information Products Pollution Control Regulations" to be implemented in 2007. Implementation of these regulations requires companies to electronic information products shall not contain six hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers and other elements. This is the cost of manufacturing enterprises and the current manufacturing process challenges. Therefore, companies want the system to be able to assist the user to adapt to the requirements of these regulations：

• In the manufacturing process will be able to contain controlled substances strict distinction between materials and environmentally friendly materials；
• Able to control the manufacturing process of the material used, to prevent non-environmentally friendly materials used in the manufacture of environmentally friendly products；
• To record the use of materials in the manufacturing process, and the final product according to track the source of material batch.
