Evaluation of the collaboration of the upstream and downstream enterprises in the manufacturing supply chain is important to improve their synergistic effect. From the supply chain perspective, this study establishes the evaluation model of the manufacturing enterprise collaboration on the basis of fuzzy entropy according to synergistic theory. Downstream enterprises carry out coordinated capital, business, and information flows as subsystems and research enterprises as composite systems. From the three subsystems, the collaboration evaluation index is selected as the order parameter. The compound fuzzy matter-element matrix is established by using its improved algorithm. Subordinate membership and standard deviation fuzzy matter-element matrixes are constructed. Index weight is determined using the entropy weight method. The closeness of each matter element is then calculated. Through a representative of the home appliance industry, namely, Gree Electric Appliances Inc. of Zhuhai, empirical analysis of data in 2011-2017 from the company and its upstream and downstream enterprise collaboration shows a good trend, but the coordinated development has not reached stability. Gree Electric Appliances Inc. of Zhuhai need to strengthen the synergy with upstream and downstream enterprises in terms of cash, business, and information flows to enhance competitiveness. Experimental results show that this method can provide precise suggestions for enterprises, improve the degree of collaboration, and accelerate the development and upgrading of the manufacturing industry.

Facility layout problems (FLP) are usually treated as design problems. Lack of systematic and objective tools to compare design alternatives results in decision-making to be dominated by the experiences or preferences of designers or managers. To increase objectivity and effectiveness of decision-making in facility layout selections, a decision support model is necessary. We proposed a decision model, which regards the FLP as a multi-attribute decision making (MADM) problem. We identify sets of attributes crucial to layout selections, quantitative indices for attributes, and methods of ranking alternatives. For a requested facility layout design, many alternatives could be developed. The enormous alternatives, various attributes, and comparison of assigned qualitative values to each attribute, form a complicated decision problem. To treat facility layout selection problems as a MADM problem, we used the linear assignment method to rank before selecting those high ranks as candidates. We modelled the application of the Nemawashi process to simulate the group decision-making procedure and help efficiently achieve agreement. The electronics manufacturing service (EMS) industry has frequent and costly facility layout modifications. Our models are helpful to them. We use an electronics manufacturing service company to illustrate the decision-making process of our models.

Today's manufacturing enterprise relies heavily on the collaboration and coordination among the distributed manufacturing systems. The effective exchange of the various manufacturing information among the distributed organizations contributes a great deal to their productivity. An Internet-Based Manufacturing Desk is developed for the production of the press dies in the automobile industry in order to solve the manufacturing problems among the distributed organizations, to maintain their smooth and immediate information flow, and to increase their productivity finally. The CBR(Case-Based Reasoning) method is applied to achieve those effects. Using the method, the solutions and methods of the predetermined case-bases are retrieved and applied to solve a newly introduced problem. The developed system is implemented and applied successfully.

The primary goal of the requirement analysis phase during information system development is to identify and document what is really needed, in a form that clearly communicates to the user and to development team members. Presented in this paper is a QFD(Quality Function Deployment)-based requirement analysis method and procedure for developing a large-scale enterprise information system. For the purpose of elicitation of software functional requirements, this paper adopts the method of HOQ(House Of Quality) and proposes a simplified HOQ which is more suitable for the software requirement analysis. As a result of this paper, it suggests desired functionalities for an integrated design &manufacturing information system.

Common problems have been observed in the existing Information Requirements Analysis (IRA) methodologies such as BSP(IBM), CSF(Rockart), or ISP(Information Engineering), etc. These methodologies require too much time and human resources for the IRA process, involves high complexity, and their IRA outcomes are frequently biased by the subjective views of the people involved. In this paper, we introduce a new methodology for the enterprise wide information requirements analysis utilizing templates and nine closed-ended questions. Extending the BIAIT(Business Information Analysis and Integration Technique) method, this methodology presents nine question about each firm's order type(7Q's for customer side and 2Q's for supplier side) to derive information processing characteristics of the firms. As the central component of this methodology, data and process templates for the manufacturing industry were established. To validate the methodology, suitability of the data and process templates were examined through six real world business cases.

In order to promptly cope with the various requirements of consumers, the environment of product development is being globalized in manufacturing industrials. For this reason, it is necessary to build up an efficient collaborative system for communication between remote area designers. Specially, while Internet and information technologies were merged with the manufacturing or business process, the research for collaborative system has become an important issue. Therefore, we propose a Web-based Engineering Collaboration Framework using SPS(SharePoint Portal Server) which is an enterprise business solution that integrates information from various system into one solution through single sign-on and enterprise application integration capabilities, with flexible deployment options and management tool. Through a Web-based Engineering Collaboration Framework, designers can share knowledge assets and have a remote conference with others via web.

Recent trends require that access to the device/equipment information be provided from several locations or anywhere in the enterprise. One example is virtual machine/manufacturing system (VMS) where predictive maintenance is performed both on factory floor and in remote site through internet ［1］. Internet access is increasingly available and affordable, and along with the "internet" is the backbone of modern enterprise data networks. Typical functions of such a system includes monitoring and control for diagnosis and remedy action in realizing preventive maintenance.(omitted)

In this paper, we propose a workflow framework for the integrated logistics systems. We modelled the logistics activities into workflows, which allow clear specification and flexible modification of business processes. To specify workflows, we used petri-net that is extended to handle with information flows. A framework to implement the integrated logistics system using workflow management technology is proposed. Since logistics is closely related with other parts of enterprise such as manufacturing and accounting, the framework could capture a rich features required for enterprise-wide systems.

In recent years, the main concerns of enterprise management activities is how to strengthen the competitiveness to quickly respond to changes and sustain the growth in business environment. In order to achieve competitiveness and sustainability, a large variety of production informatization systems, such as MES (Manufacturing Execution System), ERP (Enterprise Resource Planning), have been introduced to manufacturing companies. However, there have been many problems owing to the reckless introduction of those systems. Therefore, it is necessary to evaluate the informatization level of the manufacturing company before introducing production informatization systems. This paper presents methodology and system to evaluate the informatization level of manufacturing company. The proposed evaluation method, based on the traditional questionnaire approaches, considers the various characteristics of the company. And then, we proposed models for calculation and production informatization level using 450 results of conducting a survey. Finally, a web-based system was developed for the evaluation of informatization level.
