Logistics center is the collection class,the information flow and the fund flows to a body thing logistics net winds the pitch point,has the vital role to the modern social economy development.It through to the commodity transportation, the packing,the loading and unloading transporting,the circulation processing,matches delivers,the information processing and so on carries on the scientific management,may greatly reduce the work the labor intensity,reduce the commodity to lose,enhances the stock velocity,the acceleration circulation of commodities,reduces the circulation cost,enhances the social demand of the satisfied degree.Each working-area of the logistics center,the storage-area is the most important,also is not the easiest to plan,according to the statistics,logistics center to unload cargo,to take the goods,sorts and loads a car the link work generally to occupy entire flows the central total work time40%,when other approximately 60% work time actually are the operating personnel walks consumes, walks consumes when mainly is because the storage-area of logisticscenter planning not to be unreasonable,therefore said the reasonable planning the storage-area allowed to reduce transporting expense of logistics center,enhances the work efficiency of logistics center.This article flows the center take the thing to the storage-area of logistics center planning design as the research content,to the storage-area planning and design method to carry on quite comprehensive,the thorough exploration and the research,hoped could for the storage-area the reality to planning the certain instruction and the model function. This article research content mainly includes following several aspects:1.The theory of planning and design the storage-area of logistics centerFirstly introduce the concept,the type,the basic function of logistics center as well as the thing flows central the development tendency,Then summarize the storage-area of logistics center,and introduce the many kinds of storage way of the storage-area,Finally the more detailed elaboration classics basic data analysis method-EIQ analytic method,including this EIQ analytic method step,as well as this analysis method flowed in the work system in the thing the application.2.The storage-area planning of logistics centerThis part mainly elaborated below the content(1)The methods of logistics center scale determination.Firstly,analyzes the scale to determine two kind of influences factors,Then flows the central scale to the thing to determine the method has conducted more thorough research,proposed the application supply and demand principle of detailed balance determination the logistics center scale,and has carried on the analysis to parameter.(2)The methods of storage-area of logistics center scale determination. Firstly,according to the goods of frequency of the storage-area to propose the planning model of storage capacity of storage-area,Then in view of the different storage way, proposed the single-layer pallet storing,folds the material frame to storing,pallet and goods shelf and so on the many kinds of storage way of area model of storage-area;Finally has carried on the introduction to the hight determination of storage-area,and has produced the reference value according to the different warehouse.(3)The methods of equipment choice of storage-areas of logistics.Firstly, elaborated some basic principles of the equipment chooses,Then introduced storing equipment as well as the carrying equipment type,the characteristic, and the choice method,simultaneously conduct the research to the carrying equipment disposition quantity,proposed the choice model,Finally introduced applies EIQ in the analysis the IQ curve to choose the equipment the method.(4)The channels planning of storage-area of logistics center.Firstly, elaborated the channels type of storage-area,as well as channel planning and design principle,Then introduced under the channel establishment way as well as the different establishment way channel area taking rate,may choose the channel in the practical application according to this point the establishment way;Finally proposed the person good channel,the handcart channel as well as the forklift channel width design model,and has conducted more detailed research to the forklift channel width,divides into the forklift channel the straight line channel,the T-shaped channel as well as thesmallest right angle channel,separately studies the above three kindof channels the width design method.4.The slotting planning of storage-area of logistics centerThis part mainly elaborated below the content(1)Slotting code and cargo serial number.Firstly,introduced the method of slotting code,the cargo serial number,which kind of goods as well as each method separately is suitable for,Then introduced the slotting code and the cargo serial number application should pay attention question.(2)Slotting planning thought and its principle.Firstly,propose the basic though of slotting planning,after namely the slotting planning concept as well as slotting carry on the planning can bring any advantage,Then introduced the basic principle of slotting planning,these principles are the basis of establish the slotting planning model.(3)The basic information of slotting planning.These basic information including storage space characteristic material and cargo characteristic material as well as cargo mobile information(cargo sales volume, reserve and so on).(4)The model establishment of slotting planning.Firstly,propose the goal of slotting planning,establish the model of slotting planning according to the goal,mainly considered two aspects the questions,firstly consideration the cargo velocity,secondly consideration the stability of goods shelf,the goal is make the velocity of high cargo to put in the slotting which is easy to sort takes,thus enhances the goods efficiency sorting,Let the heavy cargo put as far as possible on under,the light cargo puts on above,make the center of gravity of goods shelf always lowest,lets goods shelf stress be even,guarantee goods shelf structure stability.(5)The algorithm determination of slotting planning.Considered the slotting planning is more than an goals optimizations question,after analysis many kinds of algorithms advantages,finally chooses genetic algorithm to carry on the solution. Firstly,introduce the genetic algorithm solving the multi-goals optimization question method,Then according to the characteristic of the slotting planning model,propose the application compound trial-and-error method,the multi- sexes enter the method which the reduction and the restraint method unifies to carry on the solution,Finally carries on the coding using MATLAB,obtains the optimal solution of the slotting planning question.5.Demonstration.The method and the procedure proposed which the paper in apply to something storage-area of logistics center planning and design,and carry on the analysis to the planning.6.Summary and Prospect.Summarize the conclusion of the investigation and give some conceived plans.The innovation of this paper mainly manifests in the below aspect.1.The synthesis considered the cargo velocity as well as the cargo weight, build this simulated target model of slotting planning.propose the application compound trial-and-error method,the multi- sexes enter the method which the reduction and the restraint method unifies to carry on the solution.2.Use MATLAB7.0 to establish the slotting planning procedure,apply the coding method of natural number into the coding of slotting planning,uses inregularly method of crossover and mutation,after evolves 500 generations,obtains the final optimal solution of slotting planning.
