Inspired by the practice of urban distribution fresh products, we introduce a new electric vehicle routing problem with soft time windows. In this problem, goods different temperature layers can be distributed in ordinary vehicles simultaneously based on cold storage insulation box. The primary objective is to devise optimized routes for logistics companies minimize costs, including transportation, refrigeration, and charging costs. To address this, present mathematical model propose an...
With environmental degradation and energy shortages, green low-carbon development has become an industry trend, especially in regards to cold chain logistics (CCL), where consumption emissions are substantial. In this context, determining how scientifically evaluate the efficiency (CCLE) under carbon emission constraints is of great significance for achieving sustainable development. This study uses three-stage data envelopment analysis (DEA) Malmquist index model analyze overall level...
In order to overcome the low efficiency, high labor intensity and risk of steel arch support operations in tunnel boring machines, a looping manipulator with multiple actuators was designed. Firstly, simplify complex design requirements manipulator, an exponential product model established analyze influence each single joint on end output, decomposed into different modules. The is carried out separately, layer by layer, actuator-trunk module-branch module. Then, optimal obtained considering...
Safety and environmental protection are key issues in shield construction. Due to wear, the cutter of a machine must be changed after period excavation. In order realize tool change operation at atmospheric pressure, method head freezing is described this paper. The finite element simulation used analyze construction with frozen composite stratum. For stratum uneven hard soft layers ratio 1:1, stress temperature fields analyzed, around hob recorded. Through numerical simulation, field...
Mechanisms with multiple end-effectors are widely used in engineering due to their ability synchronize and collaborate on processes. However, this kind of mechanism is difficult design its high topological complexity complex applied loads. In order solve problem, article proposes a configuration synthesis method for tree-type hybrid mechanisms from two aspects: modular decomposition open-loop closed-loop power-concentrated joints. According the correlation space degrees freedom between...
Owing to the satellite signal strengths of GNSS is so low that it interfered with powerful signal, how effectively resist interference becoming a problem.In this paper,first LCMV algorithm based on power-inversion adaptive array deduced from theory in certain mathematical model ,what’s more ,for avoiding computing inverse matrix, improved and then verified through Matlab-simulation .Last,the hardware design given for realization algorithm.
This article describes the overall processing technology of ultra-long cylinder, especially internal pull hinge hole from tooling, cutting tools to machining parameters are introduced in detail solve difficult problem very long hole, cylinder accuracy is guaranteed.
A finite element method (FEM) has been developed to simulate the isothermal resin infusing process in film infusion. The FEM is based on conservation of mass at any instant time and objective infusion (RFI) fiber impregnation mold filling. computer code was able visually. numerical example presented here demonstrated that compared with traditional element/ control-volume (FE/CV), physically accurate computationally efficient.
