Linear motor has potential applications in electric vehicles because of high efficiency and convenient maintenance. However, existing researches are mainly about linear motors, rarely focusing on its loading system. Actually its complicated motion pattern requires accurate and multi-mode load simulation to evaluate output performance comprehensively. In this paper, a novel multi-mode and accurate...
Due to the complexity of split delivery vehicle routing problem (SDVRP), a simulation based optimization approach is proposed. A simulation model is used to capture the dynamics and uncertainties of the system and evaluate the system performance. Three split policies, LOS-policy, LDD-policy and LWT-policy are designed to implement the order split/consolidation. To optimize the route of orders in a...
The study in this paper covers torque modeling, trajectory planning and optimization control of current input of spherical actuators, in which the latter two are the major contributions. Trajectory planning is an effective way to improve the smoothness and stability of rotor motions. A novel three-dimensional (3D) orientation representation method based on manifold of S2 is proposed to facilitate...
This paper presents a novel two level current optimization algorithm for the control of the spherical motor. The proposed spherical motor consists of a rotor with 8 cylindrical permanent magnet (PM) poles and a stator with 24 air-core coils. An analytical expression of the torque model is obtained based on finite-element method. Based on this expression, the relationship between the motor torque and...
Bank assets allocation is one of the most important project of bank management. In this paper, we built sub-optimization models within DD model's three-period framework to study bank's assets allocation under equilibrium liquidity management strategy when bank faces depositors' early withdrawals. Our study shows that when a variety of interest rates and parameters satisfy certain conditions, the equilibrium...
Through the analysis on status quo and problems of the Ying-rui Highway construction project management, this paper firstly discusses the necessity and possibility of the optimization of the project management mode into Partnering. Based on this, the paper offers suggestions for the optimization of the project management mode into Partnering, and these suggestions include clarifying obligation-authority-responsibility...
The allocation optimization of project human resource is one of the most essential aspects in a project management. A situation with employees working on tasks that they are not well-suited for can lead to a significant loss of time and resources in addition to a sub-par product or service. This paper present a project human resource allocation method based on particle swarm optimization (PSO) in...
Traveling salesman problem (TSP) is a very hard and classical optimization problem in the field of operations research, and often-used benchmark for new optimization techniques. This paper will to bring up multi-agent approach for solving the TSP based on data mining algorithm, for the extraction of knowledge from a large set of TSP. The proposed approach supports the distributed solving to the TSP...
