生产系统的多目标分析与优化

沈阳理工大学学士学位论文I摘要随着产业结构的调整,我国成为全球制造中心的趋势将越来越明显，但作为一个“劳动密集型”为主的国家，我国人均劳动生产率和产品合格率与国外相比存在着较大的差距。本文正是在这种背景下，结合系统工程、基础工业工程、人因工程、运筹学等学科的理论和方法展开研究的。本文以天津耀华机械厂生产系统为研究对象，首先，利用系统工程的的方法对生产系统中生产效率、作业环境、成本、产品质量、安全多个目标进行分析，根据分析结果建立影响生产系统效率因素的结构模型图。其次，对影响生产系统因素运用层次分析法，对各因素进行排序，找出主要问题因素。最后，运用工业工程和人因工程学中的方法（如方法研究）对生产系统进行改善，得出改善结果，并进行改善后的评价，得到一个最优、满意、高效的生产系统。关键词：生产系统；多目标；系统工程；层次分析法；方法研究沈阳理工大学学士学位论文IIAbstractWiththeadjustmentofindustrialstructure,Chinahasbecometheworld'smanufacturingcenterofthetrendwillbecomeincreasinglyevident,butasalabor-intensivebasedcountry,China'spercapitalaborproductivityandproductqualificationratecomparedwithothercountriestherearelargegap.Thisarticleisinthiscontextthatcombinessystemsengineering,basicindustrialengineering,humanfactorsengineering,operationsresearchandotherdisciplines,theoriesandmethodsforResearch.Inthispaper,TianjinYaohuamachineryfactoryproductionsystemastheresearchobject,firstofall,theuseofsystemsengineeringapproachtoproductionefficiencyproductionsystem,operatingenvironment,cost,productquality,safetyanalysisofmultipletargets,accordingtotheresultsoftheanalysistoestablishaffectingproductionsystemsefficiencyfactorstructuralmodeldiagram.Secondly,thefactorsaffectingtheproductionsystemusingAHPtosortthevariousfactorstoidentifykeyissuesfactor.Finally,theuseofindustrialengineeringandhumanfactorsengineeringmethodsin(suchasamethodof)theimprovementoftheproductionsystem,toimprovetheresultsobtained,andmakeimprovementsafterevaluation,togetanoptimalandsatisfactoryandefficientproductionsystems.Keywords:productionsystems;multi-objective;systemsengineering;AHP;Methods沈阳理工大学学士学位论文III目录摘要.....................................................................IABSTRACT.................................................................II目录....................................................................III1绪论..................................................................11.1选题背景和意义.....................................................11.2国内外现状研究.....................................................21.3文章结构简介.......................................................22生产系统分析与优化的相关概念与理论....................................32.1多目标规划的基本概念...............................................32.1.1多目标规划的定义................................................32.1.2多目标规划的产生与发展..........................................32.2生产系统的基本概念.................................................52.2.1生产系统的定义及主要要素........................................52.2.2系统改进的原因..................................................62.2.3系统分析定义及主要内容..........................................72.3层次分析相关理论...................................................82.3.1层次分析法的基本原理与步骤......................................82.3.2递阶层次结构的建立与特点........................................82.4方法研究...........................................................92.4.1方法研究的定义与内容............................................92.4.2方法研究的层次.................................................102.4.3程序分析.......................................................103生产系统多目标分析与结构模型.........................................123.1企业概况...........................................................123.1.1公司基本情况...................................................123.1.2公司组织结构图.................................................133.2多目标分析........................................................143.3生产系统结构模型..................................................173.2.2生产系统各要素可达矩阵的建立...................................173.2.3可达矩阵R的区域与级别划分.....................................183.2.4生产系统分析解析结构模型的建立.................................194层次分析法对生产系统的分析...........................................21沈阳理工大学学士学位论文IV4.1建立层次结构模型................................................214.2建立判断矩阵并计算..............................................224.2.专家打分..........................................................224.2.2构造判断矩阵及一致性检验.......................................244.2.3层次总排序及一致性检验.........................................284.2.4运用排列图找出关键因素.........................................305生产系统的多目标优化.................................................315.1方法研究对生产系统的优化...........................................315.1.1轴承套圈磨加工工艺程序的分析与优化.............................325.1.2轴承套圈车加工流程程序的分析与优化.............................355.1.3热处理车间布置和路径的分析与优化...............................395.1.4外购件接收管理事务的分析与优化.................................415.2设备性能优化......................................................435.2.1设备的故障规律.................................................445.2.2设备更新.......................................................455.2.3制定耀华机械厂设备维修保养制度.................................475.3工作环境改善......................................................495.3.1噪声环境改善...................................................495.3.2微气候环境改善.................................................525.4其他方案优化......................................................53结论....................................................................54致谢....................................................................56参考文献.............
