A three-dimensional (3D) path planning method based on the improved mayfly algorithm (IMA) is proposed in this paper for the unmanned aerial vehicle (UAV) path planning problem under the condition of diverse static features and obstacle threats. Firstly, the 3D flight area environment model with obstacles is built. Then, the path planning method is developed, which can increase the global search c...Show More
Accurate localization is a prerequisite for robots to realize autonomous navigation. This paper proposes a robot localization algorithm suitable for indoor environments to effectively solve the problem of global localization and position tracking. First, global localization is realized by employing a two-stage matching method involving coarse and fine levels based on a branch-and-bound algorithm a...Show More
In the automotive industry, assembly line balancing work plays an important role in assembly process planning. Assembly line balancing problem is a kind of NP hard problem, especially for Two-sided assembly line balancing problem. It is too difficult to obtain the optimal result using the commercial solvers directly. This paper presents a heuristic algorithm to deal with the two-sided assembly lin...Show More
Each slab entering to the reheating furnace has an optimal and unique reheating curve. The process of obtaining the optimal reheating curve is to solve the typical Partial differential equations (PDE) constrained optimization problem. Obviously, the solution of optimization problem is determined by both the precision of the mathematical PDE model and the numerical method. Firstly, the more accurat...Show More
Total heat exchange factor plays an important role in determining the ideal temperature rise curve of the slab under steady-state conditions. The "Black Box" experiment and the furnace temperature data measured by the thermocouples in the reheating furnace contain uncertainties and big noise that will affect the identification accuracy. In order to solve the above problems, this paper proposes wei...Show More
Considering the characteristics of multimodels production pattern on assembly line, the assembly line balancing problem which is non-deterministic polynomial hard becomes more challenging to complete. In this article, we propose a reformulation of simple assembly line balancing problem based on Dantzig-Wolfe decomposition. New models of the master problem and subproblems in this algorithm are buil...Show More
In this paper, we study the initial butter decision (IBD) problem for a class of periodic production lines and the stochastic approximation (SA) algorithm for the problem. We establish the generalized semi-Markov process (GSMP) model of production line and the formulation of the IBD problem that is a bi-objective stochastic optimization problem. Considering the high computation cost of objective f...Show More
Temperature control of steel billets plays an important role in the quality of steel billets. This paper was motivated by the necessity for setting a value of spray cooling water flow with regard to the accuracy, fast applicability to real-time optimization, and capability of non-steady operation scenarios, especially for the change of casting speed. Therefore, this paper is focused on the GPU-bas...Show More
In this paper, the parallel numerical simulations of 3-dimensional (3D) mathematical model for the walking-beam type reheating furnace have been developed and implemented on the graphics processing unit (GPU) architecture. First, the detailed heat transfer processes in the furnace are described and categorized when building the 3D mathematical model. They consist of the radiative heat exchange int...Show More
This paper addresses the integrated multiobjective production planning and decomposing (P&D) problem for mineral processing. A novel multiobjective 0–1 mixed integer nonlinear programming model is presented for the simultaneous P&D problem (O-model). In order to reduce the computational cost for solving O-model, a rolling horizon-based two-level decomposition approach is proposed to separate O-mod...Show More
In steelmaking process, the process times of machines, such as LD Converter and Refinery etc. are often different with the process time of them in the schedule for the reason of Metallurgical Processes principle. When those process time change, caster operator must increase/decrease the speed of caster machine to prevent the shutdown of caster machine. At the same time, caster operator must also g...Show More
The production planning optimization for mineral processing is important for non-renewable raw mineral resource utilization. This paper presents a nonlinear multiobjective programming model for a mineral processing production planning (MPPP) for optimizing five production indices, including its iron concentrate output, the concentrate grade, the concentration ratio, the metal recovery, and the pro...Show More
