Hybrid shop floor control system for Computer Integrated Manufacturing (CIM)

A shop floor can be considered as an important level to develop Computer Integrated Manufacturing system (CIMs). However, a shop floor is a dynamic environment where unexpected events continuously occur, and impose changes to the planned activities. To deal with this problem, a shop floor should adopt an appropriate control system that is responsible for the coordination and control of the manufacturing physical flow and information flow. In this paper, a hybrid control system is described with a shop floor activity methodology called Multi-Layered Task Initiation Diagram (MTD). The architecture of the control model contains three levels: i.e., the shop floor controller (SFC), the intelligent agent controller (IAC) and the equipment controller (EC). The methodology behind the development of the control system is an intelligent multi-agent paradigm that enables the shop floor control system to be an independent, an autonomous, and distributed system, and to achieve an adaptability to change of the manufacturing environment.     

A simulated annealing algorithm for integration of shop floor control strategies in semiconductor wafer fabrication

The semiconductor manufacturing industry is one of the most important industries in Taiwan. Wafer fabrication is an essential process in semiconductor manufacturing. However, controlling the production system on the shop floor is extremely difficult owing to the complicated manufacturing process and reentrant characteristics. In this paper, the shop floor control (SFC) integration strategies (order review/release, dispatching, and rework strategies) in wafer fabrication are considered with using several performances. We reviewed the literature on SFC strategies in wafer fabrication. The proposed combination simulation and simulated annealing (SA) algorithm is presented for SFC strategies in wafer fabrication. The objective was to seek the near global optimum solution for the combination of SFC strategies for a specific performance indicator. From the results, the proposed methodology was found to perform well for combinations of SFC strategies using different performance indicators in wafer fabrication. However, no single combination of SFC strategies could satisfy all performance indicators. Hence, considering the trade-off among these production control strategies, a suitable strategy should be chosen based on the system control tactics. Considerable computational time was saved in this research.     

APPLICATION OF IMPROVED PRODUCTION ACTIVITY CONTROL ARCHITECTURE FOR SHOP FLOOR INFORMATION SYSTEM IN DIGITAL MANUFACTURING

Shop floor control (SFC) is responsible for the coordination and control of the manufacturing physical and information flow within the shop floor in the manufacturing system. Weaknesses of the production activity control (PAC) architecture of the shop floor are addressed by the Maglica's new system architecture. This architecture gives rise to unlimited number of movers and producers thus evolving more complex but decentralized architecture. Beijing Institute of Technology - production activity control (BIT-PAC) architecture introduces an idea of sub-producers and sub-movers thus reducing the complexity of the architecture. All the equipments including sub-producers and sub-movers are considered to be passive in the proposed shop floor information system. The dissemination of information from sub-producers and sub-movers is done manually through a PC. Proposed BIT-PAC SFC architecture facilitates the information flow from shop floor to the other area of the organization. Effective use of internet information services (IIS) and SQL2000 is done along with the ASP.NET technology to implement the application logic. Applicability of the software based on BIT-PAC architecture is checked by running application software on a network PC that supports the dynamic flow of information from sub-producers and sub-movers to the other parts of the organization. Use of software is also shown at the end for BIT training workshop thus supporting the use of SFC architecture for similar kind of environments.

A formal model for incorporating shop floor controls into plant information systems

The high cost and long development cycle of shop floor controls (SFC) have prevented many small, medium, and even large-size manufacturers from deploying plant-wide, real-time information systems. In order to stay competitive in a make-to-order business model, such systems are essential. In addressing the obstacles to such systems, this article proposes a formal method that ensures that a built SFC can be applicable to a plant-wide, real- time information system. By taking advantage of both the linear growth of the complexity function in a structured adaptive supervisory control model, and the real-time responses of a virtual production line based e-Manufacturing system, a formal method for creating an integration-ready structured adaptive supervisory control model (iSASC) for a discrete manufacturing system is introduced. An iSASC-based SFC prototype system was successfully tested and evaluated in an industrial site.
