다국어 초록 (Multilingual Abstract)

This thesis developed a control and operation system for model plant. The model plant, which was made by Fishertehnik co., consists of AS/RS module, manufacturing cell module, assembly module and supplementary material handling equipments. Therefore, it is necessary to understand of the information and communication protocol between the machines by using the HLI function. An efficient development of the operating model plant system is the final technical goal of this study.
Due to various customer demands and increasing competitive environments, flexibility has become an important factor of a manufacturing system. Cellular Manufacturing System (CMS) is an important application of GT in which families of parts are produced in manufacturing cells or a group of various machines, which are physically close together and can entirely process a family of part. The cell formation problem with multiple objectives is more difficult than a single objective problem. The MOGA (Multiple Objectives Genetic Algorithm) procedure uses the concept of Pareto Optimal Solution in the selection process as a variant of elitist strategy in the thesis.
To develop the operation system on plant level, the considerations are required to avoid the confliction and deadlock in system. Specifically, a shop floor control hierarchy has been developed of based on the behavior and state of specific shop floor equipments and is described in thesis. The Petri-net was used to investigate the dynamics of model plant, e.g., the relation of material handling equipments and machines.
The concepts of Object Oriented Programming (OOP) was adopted and designed to analyze manufacturing cell and assembly line of model plant. It is the function of the control architecture to design these operation software responsibilities to specific control object components. Thus, each machine device is defined by an object which limited set of manufacturing control decision responsibility.
The results of this study are used important materials for understanding of CIM and operation management parts. The proposed MOGA method for cell formation was provided the fundamental of CMS on model plant. Petri-net was useful to keep away an avoidance of collision of inter the equipments and deadlock of the sharing the resources. The OOP approaches were guided a good tool for developing software on substitute noun and verb of machine for object. Especially, it is possible to teach text-based lecture and experiments of the shop floor environments by result of this thesis. Moreover, this study was proposed the main issue for the educational purpose to design AS/RS system, develop the program and handle of materials etc.
