چکیده

Composition of processes for virtual enterprises is a significant issue. Although the flexible architecture provided by holonic manufacturing system (HMS) paves the way for adaptive composition of virtual enterprise processes, it also poses challenges in planning processes for virtual enterprises. The challenges are due, in part, to the loosely coupled structure of holons and also to the complex interactions among holons. Development of new methodologies is required to optimize the holonic processes in HMS to achieve the objectives. In this paper, we concentrate on the development of method for the composition of holonic enterprises processes. We consider the holonic processes composition (HPC) problem to synthesize processes with minimal costs while meeting the timing constraints in HMS. We propose a two-layer contract net protocol to find the minimal cost solution. We implement a problem solving environment to solve HPC. We illustrate how to apply a multi-layer contract net protocol to find the optimal solution by using an example. Keywords— Contract net, holonic, multi-agent system, Petri net, workflow, virtual enterprise.

A Fuzzy Mathematics Approach to Modeling Emergent Holonic Structures

This paper proposes fuzzy entropy minimization as an emergent property of holonic structures. When applied in the context of multi-agent systems this emergent property leads to automatic clustering of the agents into holonic organizations. When modeling enterprises as software agents the property turns into an inherent characteristic of holonic virtual organizations that enables clustering the ...

Modeling Lateral Communication in Holonic Multi Agent Systems

Agents, in a multi agent system, communicate with each other through the process of exchanging messages which is called dialogue. Multi agent organization is generally used to optimize agents’ communications. Holonic organization demonstrates a self-similar recursive and hierarchical structure in which each holon may include some other holons. In a holonic system, lateral communication occurs b...

A Norm-Governed Holonic Multi-agent System Metamodel

Modeling and designing systems that require a high level of coordination, control and automation is a very difficult task. The problem is the lack of design processes able to cover all the features these systems present. This paper presents an extension of the ASPECS metamodel for supporting organizational and normative principles and it allows to define models not only from an holonic agent vi...
