Development and Evaluation of a hierarchical artificial hormone system for task allocation in large scaled distributed systems (HiKüHoS).

人工激素系统(AHS)是一种灵活的、健壮的、实时的分布式系统任务分配概念。它满足自配置、自优化和自愈的特性。因此，它能够自主操作，并简化了其开发者或用户对系统的配置和维护。HIKüHos项目的目标是在大规模分布式系统(即10000个处理单元)中实现AHS的特性。在项目的前两年，我们研究和开发了HIKüHos项目的基本概念和技术。基于前两年的发现和经验，我们希望继续我们的研究，并使该项目成功结束。首先，应完成已初步申请但尚未批准的第三个项目年的剩余工作包(详细的比较评估、实际应用中的可用性)。此外，我们在前两个项目年发展的一个新想法是将层次结构的想法扩展到递归的多级拓扑结构。例如，这种拓扑可以在网络建筑(工厂、智能家居)和智能城市中找到。通过扩展著名的AHS可以实现递归的多级人工激素系统。在一个层次内，任务分配将由几个水平的AHS来处理。为了管理相邻级别之间的任务分配，将引入垂直AHS。该概念支持许多不同的拓扑，并减少了通信负载。申请人确信，继续HIKüHos项目的研究工作将大大促进具有Self-X特性的健壮、实时的任务分配领域的研究。

The artificial hormone system (AHS) is a flexible, robust and real-time capable concept for the task allocation in a distributed system. It fulfills the properties of Self-Configuration, Self-Optimization and Self-Healing. Thereby it is capable of an autonomous operation and eases the configuration and maintenance of the system by its developer or user. The aim of the HiKüHos project is to realize the properties of the AHS in large scaled distributed systems (i.e. 10000 processing elements). In the first two project years we researched and developed the fundamental concepts and techniques of the HiKüHos project. Based on the findings and experiences of those first two years, we want to continue our research and bring the project to a successful end. First of all, the remaining work packages of the already initially requesetd but not yet granted third project year shall be completed (detailed comparative evaluation, usability in a real application). Furthermore, a new idea we developed in the first two project years is to expand the idea of hierarchy to a recursive multistage topology. Such topologies can be found for example in networked buildings (factory, smart home) up to smart cities. A recursive multistage artificial hormone system can be realized by extendingg the well-known AHS. Within a hierachy level, task distribuition will be handled by several horizontal AHS. To manage the task allocation between the adjacent levels, a vertical AHS will be introduced. This concept supports many different topologies and reduces the communication load. The applicant is convinced that continuing the research work in the HiKüHoS project will substantially contribute to research in the field of robust, real-time-capable task allocation with self-X properties.
