This grant provides funding for development of a 'holonic' modeling framework for manufacturing system control. It will be applied to the study of design and planning in the material handling systems domain. Holonic manufacturing systems include individual units (part, material handling device, or machine controllers) that make autonomous decisions based on guidelines or system-wide constraints provided by higher level controllers such as a cell controller or system controller. Entities (e.g, parts) and resources (e.g., material handling devices and machines) are modeled as intelligent agents that function in a cooperative manner so as to accomplish individual as well as cell-wide and system-wide goals. The framework will be used to study the impact of design decisions on planning aspects (e.g., effect of introducing three automated guided vehicles on part transportation time and traffic congestion in a material flow network). In addition to developing a promising, alternative modeling framework, a major part of the research work will focus on developing a prototype simulation model for material handling system design and planning. The model will be extensively validated as part of an assessment effort and tested for stability and convergence. Thus, a generic MHS model will be developed, a prototype of the framework implemented, and experimentation conducted to allow for quantifiable performance assessment. If successful, results of this research will demonstrate applicability of the holonic modeling framework in the material handling systems domain. This in turn will enable researchers to consider its application to higher level integrated manufacturing planning and design problems. This project has the potential of significantly benefitting the material handling industry, including designers, manufacturers and users of materials handling systems.

该基金为制造系统控制的“子整体”建模框架的开发提供资金。 它将被应用到研究的设计和规划在物料搬运系统域。 子整体制造系统包括独立的单元（零件、材料处理设备或机器控制器），这些单元基于由诸如单元控制器或系统控制器之类的更高级别的控制器提供的指导或系统范围的约束来做出自主决策。 实体（例如，部件）和资源（例如，材料处理设备和机器）被建模为以协作方式工作的智能代理，以便实现个体以及单元范围和系统范围的目标。 该框架将用于研究设计决策对规划方面的影响（例如，引入三辆自动引导车辆对物流网络中部分运输时间和交通拥堵的影响）。 除了开发一个有前途的替代建模框架外，研究工作的主要部分将集中在开发用于物料搬运系统设计和规划的原型仿真模型上。 该模型将作为评估工作的一部分得到广泛验证，并测试其稳定性和收敛性。因此，将开发一个通用的MHS模型，实施框架原型，并进行实验，以便进行量化的性能评估。 如果成功的话，本研究的结果将证明子整体建模框架在物料搬运系统领域的适用性。 这反过来将使研究人员考虑其应用到更高层次的集成制造规划和设计问题。该项目有可能使物料搬运行业受益匪浅，包括物料搬运系统的设计者，制造商和用户。
