Towards a Theory for Emergent Approach of Engineering Design

在人工系统(人工制品)的传统设计过程中，整个系统是通过连接各个部分(子系统)来生成的，以满足给定的规范。然而，这样的过程在很大程度上取决于人类设计师的技能。本研究透过涌现的概念，集中于分析这些人在设计过程中的能力。1.涌现设计理论的形式化在涌现概念的基础上，将一种新的设计理论表述为一个重复的过程。将进化计算应用于含歧义的设计问题，将进化计算方法应用于环境信息和规格信息不明确的设计问题。3.强化学习智能体内部状态空间的自适应构造对于在未知环境中行为的智能体，提出了一种通过强化学习来构造内部状态空间的方法。4.提出了自治多智能体系统的设计方法，并将其应用于各种调度问题。

In conventional design process of artificial systems(artifacts), a total system is generated by connecting various parts(subsystems) in order to satisfy a given specification. However, such a process depends much on the skill of human designers. This research focussed, through the concept of emergence, on the studies for the analysis of such humans' capability in the design process. The main results are following :1.Formalization of emergent design theoriesA new design theory was mathematically formulated as a repetitive process based on the emergence concept. Also human's creativity was considered in the relevant problem.2.Approach to the design problem including ambiguities by using evolutionary computingsThe evolutionary computing methods were applied for the design problems under the ambiguities on the information of environment and specification.3.Adaptive construction of internal state space for reinforced-learning agentsFor the agents behaving in unknown environment, a method to construct the internal state space by the reinforcement learning was developed.4.Design of multi-agent systemA design method for autonomous multi-agent systems was developed and it was applied for various scheduling problems.
