浅论水电规划工作思路

在水电的前期设计阶段，规划专业的重要性显而易见。由于水电规划工作涉及专业很多，如果仅停留于规划专业本身，未必能解决问题。在规划工作中，既有定量的计算，也有定性的分析；既要站在国家的角度进行评价，也要进行企业的财务效益分析；既要考虑目前的现实情况，也要对未来的发展做出预测；既有企业的主观意志，也有自然、社会历史的限制。总之，规划专业是涉及多目标、多量纲的综合判断，若以局部来通观全体，则一定要流于片面的谬误。因此，水电规划工作须进行辩证的综合研究。     

A visual tool for computer supported learning: The robot motion planning example

We introduce an effective computer aided learning visual tool (CALVT) to teach graph-based applications. We present the robot motion planning problem as an example of such applications. The proposed tool can be used to simulate and/or further to implement practical systems in different areas of computer science such as graphics, computational geometry, robotics and networking. In the robot motion planning example, CALVT enables users to setup the working environment by creating obstacles and a robot of different shapes, specifying starting and goal positions, and setting other path or environment parameters from a user-friendly interface. The path planning system involves several phases. Each of these modules is complex and therefore we provide the possibility of visualizing graphically the output of each phase. Based on our experience, this tool has been an effective one in classroom teaching. It not only cuts down, significantly, on the instructor’s time and effort but also motivates senior/graduate students to pursue work in this specific area of research.

价格不确定情况下炼厂生产计划的优化

生产计划的编制是炼油企业生产经营管理中的一个关键环节，然而由于市场变化的不确定性，使企业制度长远规划受到限制，笔者将多目标规划应用于炼厂价格不确定情况下生产计划的制定，使所得到的生产计划在一定程度上反映市场的变化并能使企业的生产效益最优，为企业管理决策者进行长远规划给予指导。通过实例验证了该方法的可行性。

An integral theorem prover and the role of proof planning

An investigation is made into the ways proof planning can enhance the capability of a rule based prover for the theory of integration. The integrals are of the Riemann type and are defined in a way to maximize the theorem proving methods of predicate calculus. Approximately fifty theorems have been proved and several examples are discussed. A major shortcoming was found to be the inability of the system to work with or produce a proof plan. As a result, a planning scheme based on the idea of subgoals or milestones was considered. With user defined plans, there was a substantial increase in performance and capability of the system and, in some cases, proofs which were previously unsuccessful were completed.     

Planning the GMAW process by constraint propagation

Although the gas metal arc welding (GMAW) process is widely used for joining metals, its planning is still a cumbersome task. The planning procedure involves many complex interrelationships among the process variables and depends heavily on empirical knowledge. Therefore, a solution method that allows a convenient way to represent the domain knowledge and evaluate the process variable relationships is needed. Further, the lack of a strong domain theory to quantify these interrelationships is a deficiency in the planning of the GMAW process. This paper presents a solution method that overcomes this deficiency and introduces a convenient knowledge representation scheme. The solution method considers the planning procedure to be a constraint satisfaction problem (CSP). The AC-4 algorithm is used to obtain arc consistency among nodes in the constraint network and the PC-4 algorithm is applied to obtain path consistency in the network. A modified version of the AC-4 algorithm is developed to reduce the search space and correspondingly reduce the computation time. An example is presented to demonstrate the capability of the method and its potential to reduce lead time.
