Experiment planning,mathematical modelling,and nonlinear optimization of the ion-nitriding process in a glow-discharge plasma

A new, efficient method for investigating and optimizing the ion-nitriding process in a glow-discharge plasma is proposed and worked out in detail for the mass kinetics of Rp-3 steel. This method, which is based on the concepts of experiment planning, mathematical modelling, and nonlinear optimization, is quite general and potentially applicable to a wide class of technological and other processes depending on several parameters.

基于栅格法的机器人快速路径规划

在栅格法表示的机器人路径规划问题研究中,定义出路径记忆量、路径方位的重要性等概念,通过可行路径中两两结点之间关联程度的改变,按照比例选择概率确定下一结点,由此得到一条新的可行路径.路径和关联程度之间形成一种正反馈机制,二者相互激励,从而简化了路径搜索方法,提高了路径搜索的效率.仿真研究表明,该算法能有效地提高路径搜索的效率.     

Evaluation of knowledge portal development tools using a fuzzy AHP approach: The case of Taiwanese stone industry

The mission of Stone Industry Development Center (SIDC) at Taiwan attempts to promote the upgrading of the Taiwanese stone industry which recently has suffered a severe depression. After several years of technical developments, SIDC tends to shift focus to efficient use of existing knowledge/information. Consequently, a knowledge portal system (KPS) is expected to be a strategic tool to improve the competitiveness of the Taiwanese stone industry. This study proposes a fuzzy AHP approach to help five domain experts individually evaluate three KPS development tools. Then, a technique to determine the weights of experts, which is used while aggregating group decisions, is addressed. Finally, the weighted geometric mean method is applied to reach the final decision.     

Time-optimal extension and retraction of robots: Numerical analysis of the switching structure

The problem of the time-optimal control of robot manipulators is of importance because of its potential for increasing the productivity of assembly lines. This work is part of a series of papers by the authors on this topic using direct and indirect methods of optimization. A cylindrical robot or a spherical polar robot constrained to the horizontal plane is considered, and optimal solutions for radial maneuvers are generated. Indirect methods are employed in order to establish the switching structure of the solutions. The results show that even such apparently simple maneuvers as extension or retraction of a robot with a prismatic joint can produce very complex optimal solutions. Time-optimal retraction can exhibit ten different switching structures with eight switching points and two singular arcs.This research was supported by the Deutsche Forschungsgemeinschaft. The results reported in this paper first appeared in the thesis of the first author and were presented at the 1989 AIAA Guidance, Navigation and Control Conference (Refs. 1 and 2).
