Performance management of communication networks is critical for speed, reliability, and flexibility of information exchange between different components, subsystems, and sectors (e.g., factory, engineering design, and administration) of production process organizations in the environment of computer integrated manufacturing (CIM). Essential to this distributed total manufacturing system is the integrated communications network over which the information leading to process interactions and plant management and control is exchanged. Such a network must be capable of handling heterogeneous traffic resulting from intermachine communications at the factory floor, CAD drawings, design specifications, and administrative information. The objective is to improve the efficiency in handling various types of messages, e.g., control signals, sensor data, and production orders, by on-line adjustment of the parameters of the network protocol.This paper presents a conceptual design, development, and implementation of a network performance management scheme for CIM applications including flexible manufacturing. The performance management algorithm is formulated using the concepts of: (1) Perturbation analysis of discrete event dynamic systems; (2) stochastic approximation; and (3) learning automata. The proposed concept for performance management can also serve as a general framework to assist design, operation, and management of flexible manufacturing systems.The performance management procedure has been tested via emulation on a network test bed that is based on the manufacturing automation protocol (MAP) which has been widely used for CIM networking. The conceptual design presented in this paper offers a step forward to bridging the gap between management standards and users' demands for efficient network operations since most standards such as ISO and IEEE address only the architecture, services, and interfaces for network management.This work was supported in part by National Science Foundation under Research Grant No. DDM-90-15173. 相似文献

The manufacturing process is one of the important processes in a product??s life cycle. The sharing of manufacturing process information among different functional application systems, such as process planning, manufacturing simulation, manufacturing execution and project management, has become difficult to implement due to the growing complexity of the manufacturing information of product, process, resource and plant. A unified representation of manufacturing process information for all applications can enable convenient integration between different application systems. The development of manufacturing-related ontology and the Process Specification Language (PSL) has provided a formal definition and structure of semantic concepts for the capture and the exchange of manufacturing information. This paper presents a manufacturing process information modelling method which builds a standard, complete and exact definition of manufacturing process data by applying current PSL specifications. New extensions of the concepts of the manufacturing process and the types of relationship for describing activities, materials and resources in a process are identified and developed. The completeness and adaptability of activity relation of the proposed manufacturing process information representation is verified using mathematical induction under a variety of complex manufacturing process situations. The ability of the modelling method in expressing complex process information is demonstrated by a machining process example. 相似文献

This paper presents a quality management system based on Manufacturing Resource Planning (MRPII). A real-time monitoring system is used to acquire the information necessary for MRPII to drive quality management over this framework. Firstly, the concept of Total Quality Management (TQM) is overlaid on the structure of MRPII. Secondly, quality management activities in manufacturing systems are used to shape the manufacturing database concept and information models of various manufacturing activities. Finally, a complete dynamic system model setting out the architecture of a proactive resource planning environment that encapsulates quality management is derived. 相似文献

Object-oriented programming (OOP) is now widely used in application software development. OOP has advantages connected with handling complexity, reusability, extendability, modularity and data abstraction, enabling it to handle modern programming requirements more effectively than conventional programming methods. Successful advanced manufacturing systems demand increasing complexity, flexibility and integration between computer applications. An object-oriented approach is particularly promising for the design and development of manufacturing information systems. This paper outlines the concepts of object-oriented methods, and describes an object-oriented application development methodology for manufacturing information systems. A CASE (Computer-Aided Software Engineering) tool is used for system modelling and for direct source-code generation. A case study describing the development of a quality management information system is presented, which was implemented using a C++ development environment. Although the research described here is concerned with quality management information systems, the proposed design methodology is applicable to other areas of manufacturing, and conclusions are drawn concerning the uses of OOP in manufacturing information systems generally. 相似文献
