Firstly, the industrial manipulators 3D model is built by using 3D software. Secondly, the 3D model is imported to the dynamic simulation software ADAMS, and the corresponding constraints and motions are added to the model according to the actual design requirements. Finally, the movement simulation is implemented and the displacement, velocity and acceleration curves of each direction for the end position and mid-position are given. The simulation results show the correctness and feasibility of the industrial manipulators 3D model. Therefore, this can provide a certain referencing value for designing industrial manipulator.
In order to allocate tasks and optimize resources well in dynamical manufacturing environment, the model for task allocation is established. An adaptive genetic algorithm (AGA) is applied to deal with it. A machine-based encoding approach is also adopted. The simulation results testify the validity of this method, and therefore the task allocation and resources optimization problem could be dealt with efficiently.
The multiple criteria decision making (MCDM) methods VIKOR is applied to the selection of the most desirable remediation for a chlorinated hydrocarbons-contaminated aquifer located in Pudong district of Shanghai. Ranking index based on the particular measure of ''closeness'' to the ideal solution is introduced. Five influential criteria (i.e. daily total pumping rate, total cost, average remaining contaminant concentration, maximum excess life time cancer risk and remediation period) and 8 alternative remediation strategies were considered. It is found that A2 is the most appropriate remediation strategy among the alternatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
