To design various optimum parameters and simulate the working process of CP single-screw compressor, the Computer-Aided Design (CAD) system for the CP single-screw compressor has been established. A new method based on computer graphics technology, database technology, object-oriented programming technology, and visual simulation technology has been adopted in this CAD system. The system has integrated solid modeling function with parameterization design function and animator simulation function based on analyzing the working principle of the CP single-screw compressor. The experimental results show that the CAD system for the CP single-screw compressor is practical and feasible.

The concept of energy internet has been gradually accepted, which can optimize the consumption of fossil energy and renewable energy resources. When wind power is integrated into the main grid, ramp events caused by stochastic wind power fluctuation may threaten the security of power systems. This paper proposes a dynamic programming method in smoothing ramp events. First, the energy internet model of wind power, pumped storage power station, and gas power station is established. Then, the optimization problem in the energy internet is transformed into a multi-stage dynamic programming problem, and the dynamic programming method proposed is applied to solve the optimization problem. Finally, the evaluation functions are introduced to evaluate pollutant emissions. The results show that the dynamic programming method proposed is effective for smoothing wind power and reducing ramp events in energy internet.

通过对现有生产调度模糊模型的分析,针对间歇生产过程,提出了一种新颖的参数模糊的通用模糊规划建模方法,模糊模型采用2种基于普通遗传算法的模糊算法,即模糊模拟和SFA算法。该方法中,参数隶属函数选取灵活,采用合适的模糊表示方式。最后通过实例验证了该模糊建模方法是一种有效的方法。

工程网络计划的基础是对各工序持续时间的估计,而导致工序工期不确定性的因素不仅具有随机性,通常也具有模糊性。文章提出一种具有LR型模糊数的线性规划模型,解决了工程网络计划的时间参数 估计和关键路径识别问题,并通过引入λ截集来充分描述决策者在不同情形下对工序工期估计的可信程度。 最后给出一实例详细说明了该方法的应用过程及有效性。
