“…Besides the failures explicitly signaled, the upper levels should be aware of other fault tolerance activities that are being performed at this level. Adlemo et al (1990) propose three different methods for achieving fault tolerance in automated manufacturing systems. Hardware reconfiguration can be performed by replacing the faulty units in a system.…”

Abstract. The complexity and diversity of manufacturing software and the need to adapt this software to the frequent changes in the production requirements necessitate the use of a systematic approach to developing this software. The software life-cycle model (Royce, 1970) that consists of specifying the requirements of a software system, designing, implementing, testing, and evolving this software can be followed when developing large portions of manufacturing software. However, the presence of hardware devices in these systems and the high costs of acquiring and operating hardware devices further complicate the manufacturing software development process and require that the functionality of this software be extended to incorporate simulation and prototyping. This paper reviews recent methods for planning, scheduling, simulating, and monitoring the operation of manufacturing systems. A synopsis of the approaches to designing and implementing the real-time control software of these systems is presented. It is concluded that current methodologies support, in a very restricted sense, these planning, scheduling, and monitoring activities, and that enhanced performance can be achieved via an integrated approach.

“…When a data or material network is partitioned, the caches enable the production to continue for a limited period of time. During this time, the system must try to perform some kind of reconfiguration in order to maintain production (Adlemo et al, 1990a). The aspects of system configuration, the problem of an optimal production allocation and a system reconfiguration in case of a production disturbance are discussed in Sections 3, 4 and 5, respectively.…”

The field of fault tolerance in computer science and engineering has been thoroughly investigated over a long period of time. A great number of different approaches have been presented on means for improving fault tolerance under certain error conditions in computerized systems. One important area that has introduced computers in order to enhance productivity, flexibility and economy, is manufacturing systems in order to acquire computer-integrated manufacturing (CIM). Using computers in a manufacturing system introduces new sources of difficulties, as well as providing new possibilities for overcoming erroneous situations that might disturb production. The aim of this paper is to describe how the use of different configurations for a manufacturing system can improve fault tolerance. One specific erroneous situation which may occur in CIM is the partitioning of a network. This situation can be handled satisfactorily by using the suggested manufacturing system configurations. Additional improvements to fault tolerance can be achieved through the introduction of data buffers and material buffers. This approach is described in this paper.

Abstract. Fault tolerance is especially important for computer systems that require a high degree of confidence. Computer Integrated Manulacturing (ClM) is an area where computer systems must not be disturbed by uncon trolled failures. This article deals with two problems that are related to fault tolerance and network partitions in automated manufacturing systems.The first problem relates to the distribution of information in partitioned data networks in CIM systems. We indicate how to overcome this problem by using the material network as a redundant data network.The second problem relates to fault detection and diagnosis in manufacturing systems. The problem is whether the indication of a fault means that a production unit itself has actually broken down, or that the indication is instead due to disturbances in the transmission of material. That is, the production unit continues to operate properly despite indications to the contrary. We describe how the material network can be used for detection and diagnosis.
