Applying a software framework for supervisory control of a PLC-based flexible manufacturing systems

In this paper, a software framework for a distributed flexible manufacturing system is presented where, as a main design goal, we consider that the functionalities are offered to other components with no effects on the robustness of the system and where security specifications are tackled without the flexibility losses. In this way, the use of the supervisory control theory (SCT) is considered. Also, a methodology that makes it easier to implement these functionalities at a PLC-based system is presented. A real application of the developed framework is presented, and the implementation is done over an industrial-size device, so the technical feasibility of the methodology is proved. As the framework considers the services offered by the device, it can be used at different manufacturing tasks, so the approach can be applied to any kind of industrial process unit.

A distributed internet-based framework for manufacturing planning

Manufacturing organizations worldwide are re-inventing their product development practices in an effort to satisfy changing customer requirements. In the context of these changes influencing the manufacturing community, there is a need to develop frameworks, architectures, and methods to facilitate the creation, implementation, and functioning of virtual enterprises (VEs). This paper presents an Internet-based framework, which supports distributed process planning activities in the context of a VE. Typically, in a VE, the enterprise partners are distributed, and possess diverse skills and heterogeneous software resources, which employ heterogeneous computing platforms. Using the developed approach, physically distributed product development partners can collaborate virtually via the Internet and integrate their life-cycle product development activities through seamless information exchange. In this framework, the distributed manufacturing resources communicate with each other via the Internet inter-ORB protocol (IIOP) using an object request broker (ORB) at each distributed site.

The application of dependency management in an integrated manufacturing network framework

Research into the effectiveness and performance of the mobile agent (MA) technology as a means of managing a domain of manufacturing devices has been conducted. However, it has been shown that MAs are not without their scalability issues. A strategic agent travelling algorithm will bring performance improvement as it allows agents to identify the best migration path in order to minimise the total expected time of searching for the desired information. The applications of process-driven dependency management along with MA techology are examined as methods for optimising the efficiency of retrieving critical information in the manufacturing environment. An integrated framework is developed to investigate the alignment of network management paradigm to the strategic management decision.     

A framework for failure recovery in a manufacturing cell

The maturity level of an automated manufacturing system can be measured by the failure-recovery capability of the system. This paper addresses the unique characteristics of failure-recovery problems in manufacturing cells, suggests a framework to cope with the problems, and presents a recovery strategy. Opportunistic and incremental problem-solving concepts of a blackboard architecture are adopted for building the framework. A case-based strategy has been developed, which uses both heuristic knowledge and historical information to resolve the cause of failures in diverse situations. An example of tool breakage is presented which illustrates the concepts of the above-mentioned framework and strategy. Prototype software has been implemented in the object-oriented language Smalltalk-80 for this purpose.
