Application of standards in the design of computer‐integrated manufacturing systems

Computational methods for planning and developing flexible manufacturing systems

“…Many system nodes (machine tools, robotic manipulators, and other devices) possess a limited number of input/output (I/O) points. Often, these system nodes are capable of only point‐to‐point communication using discrete digital I/O (Boubekri et al , 1995). When this is the case, the number of discrete messages, which may be sent to/received from the node in question, is limited.…”

“…Large savings may result from the selection of this alternative. It should be noted that leading edge equipment and control software can be quite compatible with existing hardware such as numerically controlled (NC) machining and turning centers, robotic manipulators, and programmable logic controllers (PLCs) (Boubekri et al , 1995).…”

A system solution for integration of process planning and control in flexible manufacturing

“…The idea of general FM-cell configuration for turning is presented in Figure 2. According to our assessment, structured FM-cells will have a good chance of successful acceptance in the manufacturing industry on condition that they are reliable, highly efficient and relatively cheap (Boubekri et al, 1995;Morgenweck, 1992;Siemiatkowski and Feld, 1994).…”

“…Flexible automation creates new prospects for the manufacturing industry. However, it simultaneously imposes special conditions related both to process and production planning and to controlling functions within a manufacturing system (Banaszak, 1991;Boubekri et al, 1995;McMahon and Browne, 1993;Rembold et al, 1993). The great complexity of real automated manufacturing environments necessitates the utilization of hightech solutions that consist of coupling simulation modelling and knowledge processing tools to object-oriented methods of programming intelligent manufacturing (Beaumariage et al, 1995;Siemiatkowski and Feld, 1994;Villarroel and Muro-Medrano, 1994;Zell, 1992).…”

“…An increasing tendency towards the use of the low-cost automation in manufacturing in recent years has caused a considerable number of research activities to focus on problems of configuration selection as well as the operation and control of small flexible manufacturing systems (FMSs) (Banaszak, 1991;Jacot and Ladet, 1993;Morgenweck, 1992;Siemiatkowski and Feld, 1993). The prevailing experiences worldwide (Bharali et al, 1993;Boubekri et al, 1995;Kato et al, 1993), and a study of the literature (Ganesh and Srinivasan, 1994;Niemi and Davies, 1989;Rembold et al, 1993) point to the need to develop robot served FM-cells consisting of machine tool stations, positioned in twos, where the work flow is based on demand from the cell and despatcher-set priorities.…”
