Manufacturing execution system (MES) can close the information gap whichexists between device control system and production information management system. The functions andthe web-based architecture of the MES in the extended enterprise are introduced. Using thecooperating system models of object-oriented and distributed agents and CORBA, all objects keep touniform interface standards and are easily inserted to object request broker. The utilization ofdistributed MES in extended enterprise can adapt fast change of manufacturing environment andresource. It also can improve the independent management capability of manufacturing cell and theenterprise response capability to global economic competition.展开更多

And the modeling of AMES is the key issue of realizing AMES. This paper presents an agent-based approach to AMES modeling. Firstly, the characteristics of AMES and its requirements on modeling are discussed. Secondly, a comparative analysis of modeling methods is carried out, and AMES modeling using an agent-based approach is put forward. Agent-based modeling method not only inherit the favorable features of traditional object-oriented modeling method such as data encapsulation, modularity and so on, but also has the ability to construct intelligent, rational and autonomous agent which can cooperate together to realize the goal of agile operation. A general agent architecture used in AMES modeling is described. Under this architecture, an agent can be divided into domain-independent components and domain-specific components which helps solve problems such as information overload, incomplete information handling and soft decision-making. Furthermore, an AMES model using four types of agents, i.e., interface agent, information agent, resource agent and management agent, is established. Thirdly, a snapshot of AMES model is provided in the case study. Especially, an agent-based cooperating process of task scheduling in AMES is illustrated in detail. Finally, the advantages and disadvantages of this modeling approach are discussed as well.展开更多

Methods Multiple linear regression methods was used to study the relationship and influence between executive compensation gap and R&D investment in pharmaceutical manufacturing industry based on championship theory and principal-agent theory. Results and Conclusion There is a significant positive correlation between executive compensation gap in pharmaceutical manufacturing industry and enterprise R&D investment. Listed pharmaceutical manufacturing enterprises should design reasonable salary gap between senior executives and carry out reasonable research and development activities to promote the sustainable development of pharmaceutical manufacturing enterprises. This study provides theoretical basis for optimizing executive compensation gap and increasing R&D investment in pharmaceutical manufacturing industry.展开更多
