【摘要】：装卸搬运贯穿在物流活动的整个过程中,是影响物流成本和效率的关键。大型船舶物资补给是一个典型的物料搬运系统。一般来说,该类系统优化的首要目标是提高搬运效率,缩短搬运时间,其次是减小搬运成本。对于这类优化问题,有两种研究方式,即数学模型研究方法与仿真建模研究方法。通过可视化仿真,对搬运路径规划、搬运工具配置、物资搬运顺序等进行优化研究,具有重要的现实意义。本文以“舰船备战备航物资补给流程优化与仿真”项目为背景,采用Flexsim可视化仿真技术对大型船舶物资补给物料搬运问题进行研究。总结了基于Flexsim大型船舶物资补给可视化仿真体系结构,根据大型船舶物资补给流程,明确了可视化仿真的输入条件和输出结果,分析了可视化仿真的处理逻辑。围绕仿真体系结构,给出了具体的建模步骤,分析了仿真建模中使用的Flexsim关键技术,即任务序列技术、运动学开发技术。介绍了仿真可信度概念以及主流评估流程与方法,给出了基于Flexsim的仿真可信度评估方法,即仿真模型可信度评估和仿真系统可信度评估。结合具体案例—某大型船舶物资补给可视化仿真,介绍了仿真模型和输入设置,即存储货架规则实现和任务执行器设置,针对搬运时间、搬运工具配置和物资搬运顺序问题开展了仿真研究,运用模糊综合评判对仿真可信度进行了评估。本文研究表明,Flexsim可视化仿真能够很好的模拟大型船舶物资补给物料搬运过程,在优化大型船舶物资补给流程上具有重要作用。
[Abstract]:Loading and unloading runs through the whole process of logistics activities, which is the key to the cost and efficiency of logistics. Material supply of large ships is a typical material handling system. Generally speaking, the primary goal of this kind of system optimization is to improve the handling efficiency. For this kind of optimization problem, there are two kinds of research methods, that is, mathematical model research method and simulation modeling research method. It is of great practical significance to optimize the material handling sequence. This paper takes the project of "Optimization and Simulation of ship Readiness and Readiness material flow" as the background. In this paper, Flexsim visual simulation technology is used to study the material handling problem of large ships, and the visual simulation system structure based on Flexsim is summarized, according to the material supply flow of large ships, the main contents of this paper are as follows: 1. The input condition and output result of visual simulation are defined, the processing logic of visual simulation is analyzed, the concrete modeling steps are given around the simulation architecture, and the key technologies of Flexsim used in simulation modeling are analyzed. This paper introduces the concept of simulation credibility, the main flow and method of evaluation, and gives the simulation credibility evaluation method based on Flexsim. That is, credibility evaluation of simulation model and credibility evaluation of simulation system. Combined with a specific case-visual simulation of material supply for a large ship, the simulation model and input settings are introduced, that is, the implementation of storage shelf rules and the setting of task executors. A simulation study was carried out on the issues of handling time, handling tool configuration and material handling order. The reliability of the simulation is evaluated by fuzzy comprehensive evaluation. The research shows that the visual simulation of Flexsim can well simulate the material handling process of large ships and play an important role in optimizing the material supply flow of large ships.
