Layout Planning Technology of Cellular Manufacturing System Based on Process Interconnection Analysis

With sustaining change of production mode,layout planning is no longer a thing built once for all.Cellular layout(CL) is becoming a hotspot in the research field of manufacturing system layout.Traditional researches on layout planning are mainly concentrating on aspects of layout arithmetic,style and evaluation,etc.Relatively seldom efforts are paid to CL and its specific problems as cell formation(CF),equipment sharing and CL analysis.Through problem analyzing of layout in cellular manufacturing system(CMS),research approach of cell formation,interactive layout and layout analysis threaded with process interconnection relationship(PIR) is proposed.Typical key technologies in CL like CF technology based on similarity analysis of part processes,interactive visual layout technology,layout evaluation technology founded on PIR analysis and algorithm of cell equipment sharing are put forward.Against the background of one enterprise which encounters problems of low utility of key equipments and disperse material logistic,an example of four-cell layout is given.The CL adjustment and analysis results show that equipment with high level of sharing degree should be disposed around the boundary of its main cell,and be near to other sharing cells as possible; process route should be centralized by all means,so equipment adjustment is to be implemented along direction that route intersection can be decreased; giving consideration to the existence of discrete cell,logistic route and its density should be centralized to cells formed.The proposed research can help improve equipment utility and material logistic efficiency of CL,and can be popularized to other application availably.

The Role of Planning in National Innovative City Development: On the Evolution and Implementation Effect of Shenzhen Industry Layout Planning

From the two perspectives of urban development and industrial development, this paper presents and explains the stage characteristics of the evolution process of Shenzhen to build a national innovative city, on which both the urban and the industrial policies produce remarkable influences. By analyzing three cases of industry layout planning of Shenzhen, in particular the evolution of planning thoughts and the implementation effect of the plans, this paper argues that an effective industry layout planning should focus on studying the spatial requirements of industries and creating the suitable physical environment for industrial development instead of directly arranging the layout of various industries. Moreover, the implementation of the latest planning policy in Shenzhen proves that the industry space policies issued by the local government should be problem-oriented and be aimed to solve the practical difficulties in the innovative development.

Two Generative Design Methods of Hospital Operating Department Layouts Based on Healthcare Systematic Layout Planning and Generative Adversarial Network

With the increasing demands of health care,the design of hospital buildings has become increasingly demanding and complicated.However,the traditional layout design method for hospital is labor intensive,time consuming and prone to errors.With the development of artificial intelligence(AI),the intelligent design method has become possible and is considered to be suitable for the layout design of hospital buildings.Two intelli-gent design processes based on healthcare systematic layout planning(HSLP)and generative adversarial network(GAN)are proposed in this paper,which aim to solve the generation problem of the plane functional layout of the operating departments(ODs)of general hospitals.The first design method that is more like a mathemati-cal model with traditional optimization algorithm concerns the following two steps:developing the HSLP model based on the conventional systematic layout planning(SLP)theory,identifying the relationship and flows amongst various departments/units,and arriving at the preliminary plane layout design;establishing mathematical model to optimize the building layout by using the genetic algorithm(GA)to obtain the optimized scheme.The specific process of the second intelligent design based on more than 100 sets of collected OD drawings includes:labelling the corresponding functional layouts of each OD plan;building image-to-image translation with conditional ad-versarial network(pix2pix)for training OD plane layouts,which is one of the most representative GAN models.Finally,the functions and features of the results generated by the two methods are analyzed and compared from an architectural and algorithmic perspective.Comparison of the two design methods shows that the HSLP and GAN models can autonomously generate new OD plane functional layouts.The HSLP layouts have clear functional area adjacencies and optimization goals,but the layouts are relatively rigid and not specific enough.The GAN outputs are the most innovative layouts with strong applicability,but the dataset has strict constraints.The goal of this paper is to help release the heavy load of architects in the early design stage and present the effectiveness of these intelligent design methods in the field of medical architecture.

大范围生态保护红线定标布局方法

生态保护红线勘界定标是生态保护红线划定落实之后的又一项重要工作,是常态化监管的基础和前提。当前,生态保护红线勘界定标处于摸索试点阶段,国家层面缺乏具体指导细则,省市作为生态保护红线勘界定标工作的责任主体,只能结合实地因地制宜开展,缺乏系统性、标准性。定标布局是勘界定标的关键环节,主要解决生态保护红线区域内界桩和标识牌的数量确定、拟埋设位置选择等问题。本文提出一种大范围生态保护红线定标布局方法,先将生态保护红线区域按一定尺度划分为格网单元,筛选出涉及生态保护红线边界的格网单元,再引入行政区域、人口数量、道路交通、地形类别等特征因子构建度量模型,进一步开展度量特征计算,根据特征阈值最终选定格网单元,并以最终选定的格网单元作为定标布局方案,指导界桩和标识牌数量设定及埋设点位选址。以重庆市为例开展大范围生态保护红线定标布局应用,为重庆全市域生态保护红线勘界定标工作提供了第一手资料,同时,验证了本文方法在指导省市实施生态保护红线定标布局的科学性和实用性。
