A Relation Model for Manufacturing Capacity and Information

Aiming at the difficulty of clearly defining relationship between manufacturing capacity(MC) and information due to high volume of information, this paper presents definitions of MC and production processing capacity , the sub manufacturing capability, by combining existing research. Further, MC is decomposed and represented by adopting set theory, especially production processing capacity and relative information, in details. Based on this, a relation model between MC and information is established. The model could provide support for MC calculation and assessment. Last but not least, some manufacturing sub-capacity is calculated using manufacturing information of model, which effectively supports quantitative analysis of any MC and sub-capacity. Introduction In the wake of the third industrial revolution in United States and “industrial 4.0” strategy in Germany, China, another manufacturing super power, is planning Chinese version of “industrial 4.0”“Made in China 2025”. Customizing with Chinese national situation, Professor Guo Chongqing, the academician of Chinese Academy of Sciences, emphasized the importance of MC and resources. In order to integrate MC, there are three questions to be answered: first, to determine which kind of MC is needed; second, to analyze MC in different enterprises per specific requirement; third, to figure out which enterprise(s) meets requirement based on MC evaluation. To answer the first question, we need to clarify the connotation of MC, which is the basis of MC analysis. Currently, from macro strategic economy and micro resource perspectives, scholars, both domestic and overseas, provides definition of MC. In the view of macro strategic economy, scholars, represented by R. H. Hayes, S. C. Wheelwright, Andreas, Eloisa Diaz-Garrid[1-2], point out that MC is comprised of cost, quality, flexibility, innovation, service, environment and the relationship among each element. In the view of micro, Luo yongliang[3] and other scholars perceive MC as a capacity of integrating and configuring manufacturing resources; C. Liu[4] and some scholars define MC as an effective integration of resources in the process of manufacturing work. So far, there is no general definition and standard of MC. Different research views lead to different definitions of MC. So, research purpose must be considered when defining MC. Besides, during manufacturing, manufacturing capacity and sub-capacities are a certain level achieved after integrating several manufacturing information. In order to do MC qualitative and quantitative analysis, we need to describe the relationship among manufacturing information, MC, and manufacturing sub-capacity. For the moment, relative research is only a few in references retrieved. Though, in paper [5], process capability of processing system has been formally described, to provide more persuasive evidence to MC analysis and to analyze more accurate and faster, further information breakdown is needed. In conclusion, the concepts of MC and production processing capacity, the sub capacity of MC, are provided based on previous research in this article. Moreover, manufacturing sub-capacity, especially production processing capacity and relative information, is decomposed in details and is formally represented by adopting set theory. The paper presents the relationship model of MC and information, providing information support for MC calculation and evaluation. Finally, Joint International Mechanical, Electronic and Information Technology Conference (JIMET 2015) © 2015. The authors Published by Atlantis Press 121 manufacturing sub-capacity is calculated by applying information in the model, which gives strong evidence and method to quantitative analyze any manufacturing sub-capacity and MC. Manufacturing Capacity Definition Capacity is the condition and level to achieve some goal or task. Shown in layer 1-4 of Fig.1. It determines what enterprises could do. Any enterprise, who owns certain capacity, may not compete with others. But competing with others is a way of showing capacity.
