【摘要】 生产制造仿真技术为生产系统规划设计提供了新的方法和手段，以离散事件为特征的自动化生产线系统的仿真，是基于计算机仿真技术，对生产过程进行建模，以便在设计阶段和生产运行之前，模拟出未来生产的全过程。对同种生产进行多种方案设计并建模仿真，快速有效地评价不同的工艺方案，提出资源需求计划、生产计划等等，评估和优化生产过程。 本文首先研究邮件处理中心的生产工艺过程和特点、计算机仿真技术的方法及其在生产系统中的应用，然后以邮件处理中心的典型生产工艺——包件分拣和推挂分拣生产线为对象建立系统模型，对仿真结果做出总结评价。 本文的主要工作如下：针对邮政业务，特别是邮件处理中心的邮政业务作详细的调查分析，指出邮件处理中心生产工艺的主要特征；通过详细的了解离散事件系统计算机仿真技术的研究方法，并对计算机仿真软件作了周密的调查，借鉴、分析比较其功能特性的优缺点后，根据实际情况选购了本论文所需的仿真软件工具；对报刊发行局包件分拣生产线作计算机建模和仿真，将仿真结果作分析总结；对邮件处理中心转运中心的推推分拣生产线作计算机建模和仿真，得到仿真结果并作总结分析；提出邮件处理中心自动生产线的仿真设计方法，对报刊发行局期刊发行自动化生产线作仿真设计；最后对包件分拣机上包台结构建立数学模型和计算机仿真，提出多级上包台区别设置缓冲区的方案。更多还原

【Abstract】 Manufacturing simulation technology provides a new means and method for manufacturing system design. Simulation of automation manufacturing system is based on computer simulation technology, and modeling for the automation manufacturing can simulate the process of product line in the design period. Modeling and simulating for the different scheme of the same product line provides a way to evaluate different technology schemes quickly and efficiently, to bring forward material request plan and production plan, to evaluate and optimize the processing procedure.This dissertation includes the study of production technology and its characteristics, computer simulation method and application in production system. It also includes modeling and simulating and evaluation of the sorting product line of mail process center.The main work on this dissertation is as follows: On survey of post’s operation mainly in mail process center. Indicating the main characteristics of production technology in mail process center. Knowing in detail of the computer model and simulation method of discrete event system; investigation of computer simulation software; comparison and analysis the advantage and disdvantage of the simulation software. Modeling and simulating the package sorting production line in Xinjiang Newspapers and Periodicals Emitting Office and analyzing the simulation result. Modeling and simulating the hanging sorting -production line in Urmqi Mail Processing Center and analyzing the simulationresultProposes a simulation design method for the mail center auto product line, and made a simulation design for package emitting auto product line in Xinjiang Newspapers and Periodicals Emitting Office. Modeling a mathematical model and simulate for the construction of the sorting table of package sorting machine, and proposes a scheme of discriminatingly setting the buffers of sorting table.更多还原
