This keynote paper focuses on the process plans and planning functions as the important link between the features of generations of products/product families and the features, capabilities and configurations of manufacturing systems and components throughout their respective life cycles. The challenges presented by the paradigm shift in manufacturing systems and their increased flexibility and ...

Holonic Manufacturing Systems (HMS) provides a flexible architecture to the changes and uncertainties of the manufacturing conditions. HMS has developed to meet the needs of consumers who are adapted to the capability of the company. This paper explains holon and holonic manufacturing system, analyzing the needs of the manufacturing system at the upcoming conditions, summarizes the current deve...

Future manufacturing environments will be flexible and highly automated with control systems built as networks of computers. These computers will be expected to be adaptable, reconfigurable and fault-tolerant, operating autonomously and yet cooperating to perform the manufacturing task. This MICRO project has focused on the infrastructure required for building distributed manufacturing control ...

The usage of multi-agent systems for manufacturing control seems to be sharply contrasted by classical mathematical control theory. This work emphasizes how views from both scientific fields can be combined to create the flexible and optimal manufacturing control systems of tomorrow.

During the past half century, market competition has been very intense and production companies have been trying to find more efficient ways to manufacture their products. While during the period 1960 to 1970 manufacturing cost was the primary concern, later it was followed by product quality and delivery speed. New strategies had to be formulated by companies to adapt to the environment in whi...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

This article presents an approach to embedding expert systems within an object oriented simulation environment. The basic idea is to create classes of expert system models that can be interfaced with other model classes. An expert system shell is developed within a knowledge-based design and simulation environment which combines artificial intelligence and systems modeling concepts. In the give...

Deadlock-free operation is essential for operating highly automated manufacturing systems. The seminal deadlock avoidance procedure, Banker’s algorithm, was developed for computer operating systems, an environment where very little information regarding the future resource requirements of executing processes is known. Manufacturing researchers have tended to dismiss Banker’s algorithm as too co...

Paradigms in modern production are shifting and pose new demands for optimization techniques. The emergence of new, versatile, reconfigurable and networked machines enables flexible manufacturing scenarios which require, in particular, planning and scheduling methods for cyber-physical production systems to be flexible, reasonably fast, and anytime. This paper presents an approach to flexible j...
