基于栅格法-模拟退火法的机器人路径规划

路径规划是机器人技术中的重要组成部分,分全局路径规划和局部路径规划。本文将栅格法与模拟退火法结合,采用栅格法表示环境信息。局部路径规划主要基于模拟退火法,使路径跳出局部极小点,到达目标位置。

"规划求解"在土方调配计算中的应用

土方调配计算中通常采用“线性规划”法,然而当出现数量较多的填挖区时,采用人工计算则工作量太大,而专业分析软件又往往得不到普及。以潮州供水枢纽工程库区防护Ⅱ标段第二施工区域土方工程为例,介绍一种利用Excel的“规划求解”功能解决土方调配计算的方法。     

面向对象的CAPP系统工艺知识表达

知识是人们在长期的生活及社会实践中、科学研究及实验中积累起来的对客观世界的认识与经验。工艺知识表达是CAPP系统的重要部分。本文介绍了工艺知识的种类，同时介绍了对工艺知识进行表示与组织的几种方法。以工艺知识中的制造资源为例，着重介绍了面向对象方法的概念及其描述形式。

Key technologies of layout design of recycling plants of waste refrigerators

The present situations of waste refrigerators recycling and disposing were analyzed. Three key technologies of layout design of recycling plants of waste refrigerators were presented as follows: 1) establishment of recycling process of waste refrigerators; 2) the general plane layout of recycling plants; 3) the detailed layout of workshops of recycling plants. The focus of the three key technologies is to tackle the problem of the detailed layout of workshops of the recycling plants. By adopting Petri net, the model of logistics system of workshops was established and then optimized, and finally the detailed layout chart of recycling plants was gained. By adopting E-factory, the recycling plants were simulated. The results show that the method mentioned is effective.

Systematic modeling and model handling for manpower planning systems

The primary purpose of this paper is to show an efficient way of handling models and model data in a decision support system, in which it is usual to consider several variants of a model. The model data primarily consist of model-defining data, but the same approach may be used for the generated results as well. By efficient handling is meant the handling by the computer as well as by the user. For the user it is particularly important that new models can be conveniently defined as variants of existing models. The approach is introduced within the context of a decision support system for manpower planning based on Markov models. In the mean time the same approach has been used for the implementation of other decision support systems and has been found to be more generally applicable.

Credibility and applicability of virtual reality models in design and construction

In this paper, we present the findings from an extensive study of the use of virtual reality (VR) models in large construction projects. The study includes two parts: The first part presents a quantitative questionnaire designed to investigate how VR models are experienced and assessed by the workforce at a building site. The second part includes a qualitative field survey of how VR models can be applied and accepted by professionals in the design and planning process of a large pelletizing plant. Through mainly studying persons who had little or no experience with advanced information technology (IT), we hoped to reveal the attitudes of the average person working at a construction site rather than of an IT expert. In summary, the study shows that the VR models in both projects have been very useful and well accepted by the users. Today’s information flow is, from a general point of view, considered to be insufficient and the hypothesis is that using VR models in the construction process have the potential to minimize waste of resources and improve the final result.
