The manufacturing industry, automatic production has been a crucial resource that cannot be replaced by labors. However, with the moving-abroad of manufactures and under the pressure of continuously reduce production cost, the core of production management in the manufacturing industry has lain in to increase the yield rate, lower unnecessary waste in production, and achieve excellent quality control. Smart Manufacturing Execution Systems (SMES) is now playing the role of integration. The major MESs in the present market all place the emphasis on semi-conductor, LCD panel, and modular assembling industries. The lack of identification numbers in the process of production disables the present solar cell industry to provide support and operate, and thus an MES for solar cell industry is in need.This research adopts the MES with LCD View, as the system model base. Based on the framework of prototyping constituted by information system, we proposed an SMES for solar cell industry, which is integrated with the present solar cell operation model and designed according to the framework of LCD View system.The solar cell SMES developed in this study can raise the personnel working efficiency in production and process analysis. The contribution of this study can real time analysis on quality abnormality, together with information on management, such as real time report on machine status, analysis on raw material, and production indices, the solar cell MES can facilitate production managers to make strategic decisions regarding production and improve the production as well as yield rate of products.

At present, the utilization of workstation, storage, and server in an IC design house is not frequent, even the EDA license isn't, either. If these various resources on the intranet can be integrated and effectively operated, the working efficiency will be enhanced. Therefore, how to manage these critical resources on the network is a major task to enhance the competition of an IC design house.In this research, the Grid Engine structuring a model of resource distribution can integrate the resources on the intranet to build a set of system and rule about resource distribution. Taken the IC design house as an example, a user can use the technology of the Sun Grid Engine for load sharing, batch scheduling, as well as integration of resources of software/hardware on the intranet like a single workstation. Therefore, the working efficiency will be enhanced under limited resources because of complete utilization of system resources. The results of research provides a set of model and structure for management of system resources to integrate resources on the intranet in an IC design house. A resource distribution model can be established by the system and rule of resource distribution. According to the adequate management of computing resources as well as scheduling, the corresponding hardware and software can provide the computing service. Ultimately, the efficiency in software utilization increases twice and efficiency in hardware utilization increase. Besides, the purchase package expense can be reduced.
