A SCADA oriented middleware for RFID technology

Radio Frequency IDentification (RFID) has emerged as the new technology paradigm for acquisition and information management. RFID can be used to improve significantly the efficiency of business processes by providing the capability of automatic identification and data capture. This technology introduces new challenges on data and process information management in current systems. RFID data are time-dependent and dynamically changing. In addition, data carry implicit semantics. The homogeneous data processing of such implicit semantics allows us to propose RFID middleware as a WHO–WHEN–WHERE data problem. This paper presents DEPCAS, a new middleware for RFID information based on the SCADA architecture for control systems. An application of DEPCAS is the resolution of heterogeneous situations, which solves the WHAT or context-aware to apply the auto identification data received from RFID systems in business applications.     

A framework for developing Web information systems plans: illustration with Samsung Heavy Industries Co., Ltd.

Internet technology holds many promises for enterprise information integration. Web information systems are applications that facilitate intra- and inter-firm processes and integration of myriad enterprise information systems. However, these applications require sound planning to really tap into the unique promises of the Internet and the Web technologies and add value to the enterprise. Heavy machinery industry, typified by Samsung Heavy Industries presents a good case in point. Static conventional home pages do not facilitate a manufacturer’s needs of information management in its core production and business functions. Instead, dynamic Web client capabilities must be connected with real-time enterprise databases in a cohesive plan to enhance integration of business processes. Planning of Web information systems needs a proactive review of the capabilities of the Internet technology to serve the particular needs of a firm and its customers. In this paper we describe the application of a generic Web information systems (WIS) planning framework to the construction equipment division of Samsung Heavy Industries of Korea to enhance its core business. The framework is rooted in economic principles that are shown to be the drivers of modern WIS. Further, the framework is applied to the task of developing a strategic plan of WIS for the marketing and service activities of the construction equipment division of the firm. The planning process is shown to cover most of the systems development life cycle from high level information goal setting to design of Internet-based new order managing and service part requisition sub-systems.

THE TECHNOLOGY TRANSFER OF EXPERT SYSTEMS Overcoming Barriers to Commercialization

Expert systems extend the current commercial advantage of information systems from clerical to intellectual applications. As expert systems increasingly find acceptance in the marketplace, the focus is no longer on successful research, but on successful project management. Return on investment is a critical factor that must be taken into account for a successful expert systems implementation. A great deal of preparation must be done, however, before technology transfer can be carried out in an organization. This article discusses the process of transferring expert systems technology.

End-user computing and information systems methodologies

End-user computing is a growing area within the information technology (IT) industry. The number and size of end-user-developed applications is steadily increasing, yet little attention is paid to the way in which such applications are developed, and their impact upon organizations. In this paper we examine the relationship between information systems methodologies and the end-user-computing environment. In particular, the potential benefits and disadvantages of the use of information systems methodologies for end-user-computing, and strategies by which such usage can be accomplished are discussed. This paper is partly the result of a research programme involving case studies in 34 UK organizations aimed at improving business systems.     

Information sharing and business systems leveraging in supply chains: An empirical investigation of one web-based application

Web-based supply chain applications promise to provide information sharing capabilities that will enhance the participating organizations’ information capabilities and business benefits. We performed an empirical study of a sophisticated Web-based supply chain application to determine the effect of such information sharing and business systems leveraging on business benefits. We also examined the importance of relational concurrence (i.e., shared business interests among supply chain partners), as an antecedent to both information sharing and business systems leveraging. Our work showed that both information sharing and business system leveraging provided important business benefits and that relational concurrence was only marginally related to information sharing and not at all related to business systems leveraging, limiting the significance attributed to this factor in prior research on inter-organizational systems.

Rules for expanding robot applications

A discrepancy exists in the number of installed robot systems as compared to the number of potential applications. The restrictions of potential users in the seventies can be partially explained by the imperfect technology of the equipment and the minimal knowledge of first users with regard to robot integration into installed systems. Almost half of all installed robots are applied in the areas of spot and arc welding operations in the automotive industry. Due to the expected market saturation, robot manufacturers have to develop new applications for their products. These applications can be discovered through an analysis of the interdependencies between the requirements of respective tasks and the potential of new technologies. A systematic planning process is indispensable for a successful implementation.     

CIM—the integration of manufacturing and information systems

The integration of computers within the manufacturing environment has long been a method of enhancing productivity. Their use in many facets of a manufacturing enterprise has given industries the ability to deliver low-cost, high-quality competitive products. As computer technology advances, we find more and more uses for new hardware and software in the enterprise. Over a period of time, we have seen many “islands” of computer integration. Distinct, fully functional hardware and software installations are a common base for many industries. Unfortunately, these islands are just that, separate, distinct and functional but non-integrated. The lack of integration within these information systems make it difficult for end users to see the same manufacturing data. We are finding the need for a “single image” real-time information system to provide the enterprise with the data that is required to plan, justify, design, manufacture and deliver products to the customer. Unfortunately, many industries have a large installed base of hardware and software. Replacement of current systems is not a cost-justified business decision. An alternative would be the migration of current systems to a more integrated solution. The migration to a computer-integrated manufacturing (CIM)-based architecture would provide that single image real-time information system.

The effort and skills necessary for the implementation of a CIM-based architecture would require active participation from two key organizations: Manufacturing and information systems (I/S). The manufacturing engineers, process engineers and other manufacturing resource would be the cornerstone for obtaining requirements. The ability to effectively use I/S is a critical success factor in the implementation of CIM. I/S has to be viewed as an equal partner, not just as a service organization. Manufacturing management needs to understand the justification process of integrating computer systems and the “real” cost of integration versus the cost of non-integrated manufacturing systems. The active participation of both organizations during all phases of CIM implementation will result in a effective and useful integrated information system.     

STRATEGIC BUSINESS PLANNING Aligning Business Goals with Technology

For strategic business planning to be successful in the prevailing competitive business environment, current and future technology needs must be considered. In many organizations, it is the responsibility of the IS manager to ensure that the information systems support these business needs. The IS manager must have a clear understanding of the organization's strategic business plan and must tailor IS projects to meet that plan's objectives. Enterprisewide information management and enterprise analysis can help the IS manager understand the business strategy and predict the effects of technology on that strategy.
