A Holonic Approach to Dynamic Manufacturing Scheduling
نویسندگان
چکیده
Manufacturing scheduling is a complex combinatorial problem, particularly in distributed and dynamic environments. This paper presents a holonic approach to manufacturing scheduling, which in opposite to traditional approaches, distributes the scheduling functions over several entities, combining their calculation power and local optimization. In this scheduling and control approach, the scheduling mechanism evolves dynamically to combine optimized scheduling, achieved by central entities, and distributed scheduling, improving its responsiveness and robustness.

Holonic-based Control System for Automated Material Handling Systems
In real-word manufacturing environments, finding the right job sequences and their associated schedules when resource, precedence, and timing constraints are imposed is a difficult task. For most practical problems classical scheduling easily leads to an exponential growth in the number of possible schedules. Moreover, a decision time period of hours or even minutes is too long. Good solutions ...
متن کاملProposal for a Dynamic Scheduling Architecture and Method Using an Holonic Approach
Manufacturing systems are changing its structure and organisation. Supply chain are evolving to more coupled organisations, like virtual enterprises, though maintaining the single entities autonomy, adaptability and dynamism properties. Such organisations are very different, which imply organisational and technological shift through agility, distribution, decentralisation, reactivity and flexib...
متن کاملA Holonic Manufacturing System implementation
Manufacturing systems must adapt to new challenges impacting the economy. New structures, behaviours and requirements arise in response to those challenges. These elements are systematised and different problem approaches are analysed. Multiagent concepts generally and holonic concept specially are studied. Based on its requirements and characteristics several frameworks are compared. Besides, ...

In this chapter the expression “holonic cyclic manufacturing systems” refers to complex assembly/disassembly systems or fork/join systems, kanban systems, and in general, to any discrete event system that transforms raw material and/or components into products. Such a system is said to be cyclic if it provides the same sequence of products indefinitely. This chapter considers the scheduling of ...
متن کاملA study on Real-Time Scheduling Methods in Holonic Manufacturing systems
Recently, new architectures of manufacturing systems have been proposed to realize flexible control structures of the manufacturing systems, which can cope with the dynamic changes in the volume and the variety of the products and also the unforeseen disruptions, such as failures of manufacturing resources and interruptions by high priority jobs. They are so called as the autonomous distributed...
