Even though generic modules can be verified separately, the verification of the interconnections between modules requires the whole model to be considered. A potential solution is to replace the generic modules with their functional abstractions which realise the external functional behaviour of these modules. The number of places and transitions involved in realizing the required functionality is, typically, a fraction of that used to represent complete components. This reduces the complexity of the components of the modelled system, and thus the complexity of the verification model. The verification task can then focus on the correctness of the interfaces, rather then on the internal nature of the components. In this paper, for a class of Petri net models, which can be used to represent the primary components of the AGV based FMS systems, a method that allows one to systematically construct functional abstractions is presented.<<ETX>>","PeriodicalId":201380,"journal":{"name":"ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation.

In order to solve these problems, we propose a new genetic algorithm with an age structure of a continuous generation model. The new genetic algorithm is applied to a self-organizing manufacturing system-a process which self-organizes to other processes in a flexible manufacturing system environment. The effectiveness of the genetic algorithm with age structure is demonstrated through numerical simulations of the reorganization of a press machining line as an example of the self-organizing manufacturing system.<<ETX>>","PeriodicalId":201380,"journal":{"name":"ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation.

MicroMMS: a compact abstract syntax for MMS MicroMMS: MMS的一个紧凑的抽象语法

MMS can also be applied to new areas such as building automation, field buses and remote meter reading. Such applications have much stronger constraints concerning the available processing power and memory. The use of an MMS specified in ASN.1 and its associated Basic Encoding Rules (BER) can be questioned for such applications. ASN.1 and BER very often lead to long messages (PDUs) that require a time consuming encoding or decoding process. The purpose of this study is to define a new abstract syntax for MMS that offers the same functionality as the standard MMS abstract syntax but that leads to shorter PDUs. The principle adopted is that the essence of MMS is not in its abstract syntax but in its service definition, namely the set of MMS objects, services and parameters defined in ISO/IEC 9506-1.<<ETX>>","PeriodicalId":201380,"journal":{"name":"ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation.

The case-based reasoning is a plausible approach for design problems, as knowledge in such problems is almost always fragmentary. However, it is also true that raw cases contain mistakes. In this system, model cases are extracted from raw cases, generalized somewhat, and then referred to as good designs. Using model cases is also effective to shorten inference time. This system shortened design work time by one-eighth and contributed to the standardization and inheritance of skilled design techniques.<<ETX>>","PeriodicalId":201380,"journal":{"name":"ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation.

Usually, when the condition part of a rule contains several conditions, the global truth value of the rule is given by the combination of the truth values of all the conditions, using a combination operator (t-norm, t-conorm). Using usual combination operators, however, it is not possible to express the synergistic relations that may exist among the different items in the conditions, as in the expert's knowledge. So, We proposed a new combination operator, denoted by '*and*', which can express this synergistic effect. When used with the usual combination operator, the '*and*' operator adds the synergistic effect to the area where it is necessary. Using this operator, it becomes possible to use the expert's knowledge, representing it as a usual rule. In this paper, we explain the effect when we use the '*and*' operator for the combination operator of the fuzzy control rules.<<ETX>>","PeriodicalId":201380,"journal":{"name":"ETFA '94. 1994 IEEE Symposium on Emerging Technologies and Factory Automation.

In the virtual space teleconferencing system, participants from remote locations, in reality their images, are brought together into a virtual conference room where they can hold a meeting as if they were gathered in a same place.

The general availability of powerful computers can be the foundation of a new generation of decision support systems based on concepts from general systems and control theory. We report on our attempt to develop an enterprise simulation technology for decision support and long term operations optimisation. We defined the comprehensive quality function as a global cost function for enterprise optimisation. To implement such an optimisation in practice requires an enterprise model. We look at possible ways to identify, automatically, the true hierarchical structure of an enterprise and the control loops in operation.
