The paper presents optimal control modeling study for energy-saving of belt conveyor system. Given the transport operations process of bulk terminals, belt conveyor is studied. Firstly, based on the simplified energy calculation model of the belt conveyor, an objective optimization model with the aim to improve transport efficiency and reduce transportation energy consumption is established. In the...
Given the pose adjustment and path planning of the welding mobile robot during seam tracking process, mobile welding robot and welding torch are studied. Kinematics modeling of the mobile welding robot is established, which is constrained with the slider moving area, welding torch length and so on. And then, physical System is designed and multi-objective optimization model is presented with the aims...
The rationality of Early Supplier Involvement (ESI) in product development has been well recognized in terms of transforming supply chains into integrated value systems. Despite past advancements in ESI, some of the unique issues have not been addressed for ESI in e-product configuration for mass customization. As far as variety management and online configuration are concerned, the difficulties of...
This article proposed a nonparametric test method by using Gaussian mixture model application idea for reference to evaluating the construction of index architecture. First use Gaussian mixture model to cluster analysis the index architecture. Second use rank correlation coefficient of nonparametric test method to select index architecture. Then determined the evaluate index architecture and guarantee...
Directing to the nonlinear factors existed in hydraulic servo system, this paper focuses on fuzzy PID controller whose scaling factors and membership functions are optimized by evolutionary algorithm simultaneously to achieve high performance. With the improved genetic algorithm of sub population and dynamic time variant mutation, evolutionary algorithm can search the optimal state effectively. The...
Adaptive CUSUM (namely ACUSUM) charts have received much attention recently. It is found that, by adjusting the reference parameter k dynamically, an ACUSUM chart can achieve better performance over a range of mean shifts than the conventional CUSUM chart that is designed to have maximal detection effectiveness at a particular level of shift. This article studies a new feature of the ACUSUM chart...
