IDL-XML based information sharing model for enterprise integration

CJM is a mechanized approach to problem solving in an enterprise. Its basis is intercommunication between information systems, in order to provide faster and more effective decision making process. These results help minimize human error, improve overall productivity and guarantee customer satisfaction. Most enterprises or corporations started implementing integration by adopting automated solutions in a particular process, department, or area, in isolation from the rest of the physical or intelligent process resulting in the incapability for systems and equipment to share information with each other and with other computer systems. The goal in a manufacturing environment is to have a set of systems that will interact seamlessly with each other within a heterogeneous object framework overcoming the many barriers (language, platforms, and even physical location) that do not grant information sharing. This study identifies the data needs of several information systems of a corporation and proposes a conceptual model to improve the information sharing process and thus Computer Integrated Manufacturing. The architecture proposed in this work provides a methodology for data storage, data retrieval, and data processing in order to provide integration at the enterprise level. There are four layers of interaction in the proposed IXA architecture. The name TXA (DDL - XML Architecture for Enterprise Integration) is derived from the standards and technologies used to define the layers and corresponding functions of each layer. The first layer addresses the systems and applications responsible for data manipulation. The second layer provides the interface definitions to facilitate the interaction between the applications on the first layer. The third layer is where data would be structured using XML to be stored and the fourth layer is a central repository and its database management system

A service-oriented approach to embedded component-based manufacturing automation

This thesis is focused on the application of Component-Based (CB) technology to shop oor devices using a Service Oriented Architecture (SOA) and Web Services (WS) for the purpose of realising future generation agile manufacturing systems. The environment of manufacturing enterprises is now characterised by frequently changing market demands, time-to-market pressure, continuously emerging new technologies and global competition. Under these circumstances, manufacturing systems need to be agile and automation systems need to support this agility. More speci cally, an open, exible automation environment with plug and play connectivity is needed. Technically, this requires the easy connectivity of hardware devices and software components from di erent vendors. Functionally, there is a need of interoperability and integration of control functions on di erent hierarchical levels ranging from eld level to various higher level applications such as process control and operations management services.

Towards a Service-Oriented Enterprise: The Design of a Cloud Business Integration Platform in a Medium-Sized Manufacturing Enterprise

This case study research followed the two-year transition of a medium-sized manufacturing firm towards a service-oriented enterprise. A service-oriented enterprise is an emerging architecture of the firm that leverages the paradigm of services computing to integrate the capabilities of the firm with the complementary competencies of business partners to offer customers with value-added products and services. Design science research in information systems was employed to pursue the primary design of a cloud business integration platform to enable the secondary design of multi-enterprise business processes to enable the dynamic and effective integration of business partner capabilities with those of the enterprise. The results from the study received industry acclaim for the designed solutions innovativeness and business results in the case study environment. The research makes contributions to the IT practitioner and scholarly knowledge base by providing insight into key constructs associated with service-oriented design and deployment of a cloud enterprise architecture and cloud intermediation model to achieve business results. The study demonstrated how an outside-in service-oriented architecture adoption pattern and cloud computing model enabled a medium-sized manufacturing enterprise to focus on a comprehensive approach to business partner integration and collaboration. The cloud integration platform has enabled a range of secondary designs that leveraged business services to orchestrate inter-enterprise business processes for choreography into service systems and networks for the purposes of value creation. The study results demonstrated enhanced levels of business process agility enabled by the cloud platform leading to secondary designs of transactional, differentiated, innovative, and improvisational business processes. The study provides a foundation for future scholarly research on the role of cloud integration platforms in enterprise computing and the increased importance of service-oriented secondary designs to exploit cloud platforms for sustained business performance

Examining Collaboration in Interdisciplinary Product Development Focusing on Dependencies

Product development in manufacturing industry is characterized by intense collaboration need of various stakeholders. Increasing integration of disciplines in modern products makes it more and more a challenge to arrange collaboration efficiently and effectively. Process and product characteristics as well as the architecture of information systems used in product development have to be considered. This paper introduces a methodology for the design of collaboration situations based on principles of system analysis. First, a collaboration situation is defined and modelled regarding constituent elements in the domains process, product and system. Second, a description model for dependencies in these domains is developed. Morphological analysis was applied to derive features and characteristics of the model. Third, an improvement approach to optimize a given collaboration situation is depicted. The improvement approach comprises a sensitivity model, which explicates causal relations between the dependency features. The methodology is applied to a case study from manufacturing industry

A Manufacturing Execution System using Siemens\u27 PC Based Automation Technology

The focus of any manufacturing operation is to establish better yields, reduced cycle times, increase quality, and handle dynamic demand/resource fluctuations. Over the past few years many manufacturing companies have implemented Enterprise Resource Planning (ERP) systems and they have proved themselves to be successful in achieving these goals. However, real-time data is required in order to portray an accurate account of the day-to-day and/or hourly product manufacturing operations. Retrieval of this real-lime data is a challenging task. A Manufacturing Execution System (MES) is a real-time information system that improves the performance of the shop floor operations by linking business planning, order entry, material management, purchasing and accounting to the controls on the factory equipment. Siemens\u27 PC-based automation technology is an emerging technology that appears to provide a robust architecture for integrating all elements of the manufacturing environment. Applications that range from simple control to distributed control and full-fledged MES can be developed using Siemens\u27 architecture. The primary focus of this thesis is applied research to facilitate the development of a Manufacturing Execution System to control a flexible manufacturing system, CAMCELL, using Siemens\u27 PC-based automation technology and Microsoft\u27s database technology. CAMCELL contains two CNC machining centers, assembly robots, and a vision system, all of which are interlinked by a material handling system. The software architecture of the CAMCELL is based on NIST\u27s five level hierarchy. Specifically, it contains functional modules for order entry, scheduling, and routing. In addition to these functional modules, there are various support modules. In this study, we have developed software architecture to achieve vertical integration of the process control layer, the MES layer and the ERP layer. Using Siemens\u27 WinCC software, real-time process data was collected and integrated into an MES database. The study demonstrates how order information stored in a high-level database is converted into useful information for the control layer. The study also demonstrates the ability of WinCC and Visual FoxPro to update the production data into the MES database. Various Operator interface and database screens are proposed for CAMCELL

A Complex Event Processing System for Monitoring of Manufacturing Systems

Future manufacturing systems will require to process large amounts of complex data due to a rising demand on visibility and vertical integration of factory floor devices with higher level systems. Systems contained in higher layers of the business model are rapidly moving towards a Service Oriented Architecture, inducing a tendency to push Web Technologies down to the factory floor level. Evidence of this trend is the addition of Web Services at the device level with Device Profile for Web Services and the transition of OPC based on COM/DCOM communication to OPC-UA based on Web Services. DPWS and OPC-UA are becoming nowadays the preferred options to provide on a device level, service-oriented solutions capable to extend with an Event Driven Architecture into manufacturing systems. This thesis provides an implementation of a factory shop floor monitor based on Complex Event Processing for event-driven manufacturing processes. Factory shop monitors are particularly used to inform the workshop personnel via alarms, notifications and, visual aids about the performance and status of a manufacturing process. This work abstracts the informative value of the event-cloud surrounding the factory shop floor by processing its content against rules and formulas to convert it to valuable pieces of information that can be exposed to business monitors and dashboards. As a result, a system with a generic framework for integrating heterogeneous sources was reached, transforming simple data into alarms and complex events containing a specific context within the manufacturing process
