5、系統(tǒng)的。結(jié)合目標(biāo)，影響因素和物流中心布局的條件，探討了近年來大中小城市應(yīng)用SLP物流中心的布局的急劇增加.根據(jù)物流關(guān)系和非運(yùn)銷在物流中心之間的工作單位的關(guān)系，作者決定根據(jù)工作單位的位置,繪制出初始位置關(guān)系圖。通過基于移動(dòng)線及其他因素進(jìn)一步修正和調(diào)整，筆者得到可行的布局規(guī)劃。最后，本文以江蘇省醫(yī)藥物流中心為例，對(duì)其進(jìn)行了設(shè)計(jì)、分析、評(píng)價(jià)，為服務(wù)體系布局提供一定的理論依據(jù)和方法參考。關(guān)鍵詞：SLP 物流中心 布局 設(shè)計(jì)2.1引言自進(jìn)入二十一世紀(jì)，物流產(chǎn)業(yè)在中國得到了迅速的成長(zhǎng)，物流中心的數(shù)量也急劇增加。全國各地許多大型和中型城市正計(jì)劃設(shè)立物流中心。物流中心是綜合性的，大量材料區(qū)域性集中,它是一個(gè)中

6、介于生產(chǎn)和銷售之間的的企業(yè)，整合了商品流,物流,信息流和現(xiàn)金流。物流中心的合理布局獲得了越來越多的關(guān)注，這也是許多學(xué)者研究的熱點(diǎn).首先，人們用他們的經(jīng)驗(yàn)和感覺去設(shè)計(jì)物流中心。在上世紀(jì)50年代，從傳統(tǒng)的小系統(tǒng)到大的復(fù)雜系統(tǒng)的開發(fā)，只有經(jīng)驗(yàn)是很難設(shè)計(jì)物流中心的。因此，與不同學(xué)科的融合發(fā)展，系統(tǒng)工程的概念和系統(tǒng)的分析方法已經(jīng)在布局規(guī)劃中使用，以及一些更先進(jìn)的設(shè)計(jì)方法已經(jīng)逐漸顯露.其中最具代表性的方法是在1961年由美國的R。Muther提出系統(tǒng)布局規(guī)劃（SLP)。設(shè)施布局問題研究是在SLP的基礎(chǔ)上從定性的階段發(fā)展到定量階段。 SLP也被廣泛應(yīng)用于各種生產(chǎn)系統(tǒng)和服務(wù)的系統(tǒng)。最后，它提高了SLP的水平。

7、2.2目標(biāo)，影響因素和物流中心布局的條件2。2.1物流中心布局的目標(biāo)確定物流中心的位置后，物流中心布局的總體目標(biāo)是使物流活動(dòng)過程中的人員、設(shè)備和物質(zhì)空間處于最合適的分配和最有效的組合。具體目標(biāo)可以是物流總成本最小，工作單位間彼此接近關(guān)系密切，簡(jiǎn)化運(yùn)輸路線，縮短相似工作單位之間的距離,避免迂回運(yùn)輸?shù)鹊取?.2.2物流中心布局的影響因素布局設(shè)計(jì)對(duì)生產(chǎn)性能或服務(wù)系統(tǒng)的性能有顯著影響。對(duì)于一個(gè)物流中心，其布局對(duì)物流，信息流，物流運(yùn)作效率，成本，以及整個(gè)系統(tǒng)的安全性有直接影響。所以,對(duì)物流中心布局的影響因素如下：1。物流中心的性質(zhì)和功能。由于物流中心的性質(zhì)和功能不同，所以選擇設(shè)備種類和數(shù)量是不同的。物流

8、中心的規(guī)模和布局也不一樣。據(jù)其核心功能，物流中心有三種類型:中轉(zhuǎn)物流中心，倉儲(chǔ)物流中心,配送物流中心。2.物流中心的基本操作流程。物流中心的主要活動(dòng)是采購、倉儲(chǔ)、配送、流通加工、包裝、返回等.其操作過程對(duì)人員，設(shè)備和物流路線有影響.3。工作單位之間的物流關(guān)系和非物流關(guān)系。物流的關(guān)系是，有工作單位之間的物流聯(lián)系。與人際交往、行政事務(wù)等活動(dòng)可以表示為工作單位之間的非物流關(guān)系.關(guān)系緊密程度高的工作單位應(yīng)相互靠近。2。2。3SLP在布局物流中心的適用條件在適用于SLP物流中心布局需要明確的5個(gè)基本要素，即P（物流產(chǎn)品)，Q（物流量)、R（物流路線）、S（服務(wù)部門），和T(物流作業(yè)時(shí)間或技術(shù)）.前兩個(gè)基

9、本要素是最重要的.不同的物流產(chǎn)品對(duì)倉儲(chǔ)、裝卸、物流等物流活動(dòng)有不同的要求.最終，它會(huì)導(dǎo)致不同的物流路線。更為不同的是,采用不同的物流設(shè)備和技術(shù)，決定了物流運(yùn)作的時(shí)間。物流中心的工作數(shù)量反映所有單位的物流強(qiáng)度;物流路線、距離、和物流強(qiáng)度的影響,這反映在物流成本與效率。因此，SLP可以在基于物流產(chǎn)品類別,物流量和其它因素物流中心的布局中使用。2。3基于SLP布局的主要步驟在SLP的引導(dǎo)下，第一個(gè)步驟是使用量化的方法來分析工作單位之間的物流關(guān)系和非物流關(guān)系，然后找到工作單位之間重復(fù)的關(guān)系。工作單位之間的密切程度決定了工作單位之間的距離。根據(jù)這個(gè)我們可以安排它的位置。通過進(jìn)一步的修改和調(diào)整,根據(jù)移動(dòng)線

10、路等因素,我們可以得到可行的布局方案.具體布局程序如下。2.3。1物流操作流程和工作單位的設(shè)置 物流中心的主要活動(dòng)是采購、倉儲(chǔ)、配送、流通加工、包裝、返回等。在規(guī)劃設(shè)計(jì)之前，必須明確物流的主要運(yùn)作流程。然后，我們分析了相應(yīng)的P，Q，R，S和T的元素。根據(jù)分析，我們可以劃分工作單位.2.3.2工作單位之間的相關(guān)分析用物流強(qiáng)度來描述工作單位之間的物流關(guān)系是合理的。物流強(qiáng)度分為五個(gè)行列:A，E，I，O和U，如表2。1所示。我們可以使用由R.Muther提出的關(guān)系緊密程度來形容工作單位之間的非物流關(guān)系。如果兩個(gè)單位有活動(dòng)頻繁，他們的關(guān)系親密程度高，反之亦然。首先，關(guān)系密切程度分為六個(gè)等級(jí)：A，E，I，

11、O，U和X，如表2。2所示。然后，列出密切的關(guān)系（見表2。3）的原因。利用這些信息，我們可以確定工作單位之間的相關(guān)性。根據(jù)相關(guān)度越高，距離越近。2。3。3工作單位之間的綜合關(guān)聯(lián)分析整合物流關(guān)系和非物流關(guān)系。根據(jù)每個(gè)關(guān)系的一定的權(quán)重，計(jì)算工作單元i和工作單位 j （i, j = 1， 2，, n和j i）之間的復(fù)合相關(guān)性。表2.1物流強(qiáng)度等級(jí)物流強(qiáng)度標(biāo)志物流路線的比例（%)物流量（）絕對(duì)重要A1040極其重要E2030重要I3020一般重要O4010不重要U表2.2關(guān)系密切程度的分類標(biāo)志關(guān)系密切程度比例（%）A絕對(duì)重要2-5E極其重要310I重要5-15O一般重要1025U不重要45-80X忽略

12、(或負(fù)的密切程度）自由決定的序號(hào)原因1使用普通的原始記錄2共用設(shè)備或場(chǎng)地3物料搬運(yùn)4頻繁的接觸和文件交換5安全與污染6連續(xù)工作流程7可管理的8其他表2。3親密關(guān)系的原因2。3.4確定所有工作單位的相對(duì)位置，并最終得到可行的布置方案設(shè)計(jì)一個(gè)物流中心的布局,第一步不是直接考慮占地面積和所有的工作單位的形狀，而是考慮單位之間的復(fù)合相關(guān)性。如果兩個(gè)工作單位的復(fù)合相關(guān)性較高,它們之間的距離更短，反之亦然.在布局過程中,根據(jù)序列的綜合相關(guān)度，定位不同的工作單元.如果有些工作單位在同一水平上,我們用分?jǐn)?shù)決定他們的相對(duì)位置。根據(jù)上面的步驟，我們可以得到初步的理論位置的單位，然后,我們得到最終可行的布局計(jì)劃通過

13、進(jìn)一步修改和調(diào)整根據(jù)實(shí)際面積，移動(dòng),和其他因素.2。4案例分析本文以醫(yī)藥物流中心為例，根據(jù)藥品物流、移動(dòng)路線、實(shí)際地面條件，設(shè)計(jì)并分析其特點(diǎn).本文合理劃分各功能區(qū),解決問題的撤離,節(jié)約土地,符合有關(guān)規(guī)定，旨在驗(yàn)證可行性和SLP合理性。2.4.1商業(yè)背景Y醫(yī)藥物流中心位于江蘇省,是一個(gè)第三方醫(yī)藥物流企業(yè)。它主要提供藥品交易平臺(tái)，采購、儲(chǔ)存、揀選、包裝、配送、信息處理、和許多進(jìn)入企業(yè)的增值服務(wù).物流中心計(jì)劃覆蓋125個(gè)區(qū)域的單位。其建筑面積為180000平方米，倉儲(chǔ)面積約為80000平方米。醫(yī)藥物流中心有其自身的特點(diǎn)。藥品可以分為三種類型，即常溫藥，需要冷藏的藥品和精神藥品。這三種類型的藥物必須分

14、開存放，使用不同的存儲(chǔ)設(shè)施,并給予不同的關(guān)注。因此本文將醫(yī)藥物流中心分為以下幾個(gè)工作單位。（1）工作區(qū)；(2)到達(dá)分揀區(qū);（3）自動(dòng)存儲(chǔ)/檢索系統(tǒng)（AS / RS)；（4）冷藏區(qū)；(5）精神藥品儲(chǔ)存區(qū)；(6）揀貨區(qū);（7）包裝加工區(qū);（8）收集和發(fā)布；和（9）服務(wù)區(qū)。2.4.2 SLP的應(yīng)用分析物流關(guān)系（見圖2.1）和非關(guān)系的物流（見圖2.2）工作單位之間。 測(cè)定的物流關(guān)系和非物流關(guān)系的相對(duì)重要性. Y的醫(yī)藥物流中心，兩個(gè)關(guān)系的權(quán)重為1：1. 量化物流強(qiáng)度等級(jí)和非物流關(guān)系的緊密程度。通常情況下,A = 4，E = 3，I = 2，O = 1，U = 0,X = 1。 當(dāng)?shù)墓ぷ鲉卧臄?shù)量是N，可

16、中心的主要活動(dòng)是備貨，倉儲(chǔ)，分揀，包裝，配送，信息處理等諸多增值服務(wù)。為此，本文擬設(shè)計(jì)Y醫(yī)藥物流中心L型與U型組合（見圖2.5）.最終可行的布局方案。調(diào)整后，最終布置圖見圖2.6。圖2.1工作單位之間的物流關(guān)系圖2。2工作單位之間的非物流關(guān)系表2。4復(fù)合單位之間的相關(guān)性工作單位配對(duì)關(guān)系密切程度綜合物流相關(guān)物流關(guān)系非物流關(guān)系等級(jí)分?jǐn)?shù)等級(jí)分?jǐn)?shù)分?jǐn)?shù)等級(jí)12U0U00U13U0U00U14U0U00U15U0U00U16U0U00U17U0U00U18U0U00U19U0E33O23A4I26E24E3O14I25E3O14I26O1U01U27U0U00U28U0X-11X29U0U00U34O1O

19、結(jié)論本文著重于物流中心的布局，提出了利用SLP物流中心的布局設(shè)計(jì)，并增加了移動(dòng)線分析。通過本文的分析，主要結(jié)論如下。物流中心布局的總體目標(biāo)是使物流活動(dòng)過程中的人員、設(shè)備、材料和空間處于最合適的配置和最有效的組合。同時(shí),物流中心布局的主要影響因素的性質(zhì)、功能、基本操作流程的物流中心，物流關(guān)系,非物流關(guān)系單位之間的關(guān)系。通過案例分析,在明確P,Q，R，S和T元素情況下,它是在物流中心的布局時(shí)使用的SLP是可行和合理的.它為物流中心布局問題的研究提供了一個(gè)很好的參考依據(jù).有必要指出的一些局限性和不足。當(dāng)繪制的工作單位圖的相對(duì)位置時(shí)，人們必須不斷的調(diào)整和修改計(jì)劃以滿足相應(yīng)的條件。更重要的是,不同的設(shè)計(jì)

20、師的方式解決沖突可能會(huì)導(dǎo)致不同的設(shè)計(jì)方案。如何使用計(jì)算機(jī)仿真技術(shù)來比較方案得到布局計(jì)劃和其他計(jì)劃是我們的一個(gè)未來的研究方向。參考文獻(xiàn)Xue S (2006) Study on medicinal logistic center design and simulation.

27、 Design2.1 IntroductionSince entering the twentyfirst century， the logistic industry in China has beenrapidly growing up and the number of logistics centers has increased dramatically。Many large and medium-sized cities across the country are planning to set uplogistics centers。 Logistics center is a

28、 comprehensive， regional concentration oflarge quantities of materials， and it is an intermediary between productionand marketing enterprises, integrating commodity flow, logistics, information flow， andcash flow . The reasonable layout of logistics centers has taken more and moreattention， and it i

29、s also the research focus of many scholars。At first, people use their experience and feeling to design the logistics centers. Inthe 1950s, developed from the traditional small systems to big and complex systems,it is difficult to design the logistics centers only with experience. And so, withthe int

30、egration development of the diverse discipline, the system engineeringconcept and system analysis method have been used in layout planning , andsome more advanced design methods have gradually emerged。 One of the mostrepresentative methods is systematic layout planning （SLP) proposed by AmericanR。 M

31、uther in 1961。 Study on facilities layout problem is developed from qualitativestage to quantitative stage on the basis of SLP 。 SLP is also widely applied tovarious production systems and service systems 。 Finally， it improves to moveline SLP。2。2 The Goals, Influencing Factors, and Conditionsof Log

32、istics Center Layout2。2。1 The Goals of Logistics Center LayoutAfter determining the location of a logistics center, the overall goal of logisticscenter layout is to make the personnel， equipment， and material space in thelogistics activity process be in the most appropriate allocation and the most e

33、ffectivecombination . The specific goals can be the minimum total cost of material flow，work units1 of high relationship close degree close to each other， simplifyingtransport routes, shortening.2.2。2 Influencing Factors of Logistics Center LayoutLayout design has a significant effect on a productio

34、n performance or service system performance.For a logistics center， its layout has direct influence on logistics, information flow， the logistics operation efficiency, cost， and safety of the whole system。 So the influencing factors of logistics center layout are as follows:The nature and function o

35、f a logistics center。 Because the nature and function ofthe logistics centers is different， it is different to choose equipment type andquantity。 The size and layout of logistics centers are also not the same.According to its core function， the logistics center has three types: transitlogistics cent

36、er， storage logistics center， and distribution logistics center.The basic operation process of a logistics center. The main activities of thelogistics center are purchasing, warehousing， distribution, circulation processing，packing, returning, and so on 。 The operation process has an influence onthe

37、 move line of personnel， equipment, and material。 To realize the efficientlogistics， the basic operation process of a logistics center should be in considerationwhen layout designing。Logistics relationship and nonlogistics relationship between work units.Logistics relationship is that there is logis

38、tics contact between work units。 Andinterpersonal contact， administrative affairs, and other activities can be expressedas nonlogistics relationship between work units. Work units of high relationshipclose degree should be close to each other.2.2.3 Application Conditions of SLP in the Layoutof Logis

39、tics CenterIt is necessary to specify five basic elements， namely P （logistics products）, Q(logistics quantity), R (logistics routes), S （service sectors）, and T （logistics operationtime or technology） before applying SLP to logistics center layout. The firsttwo basic elements are the most important

40、. Different logistics products have differentdemands on storage, loading， and other logistics activities。 Ultimately， itleads to different logistics routes。 What is more, using different logistics equipmentand technology determines logistics operation time. The work quantity of thelogistics center r

41、eflects the logistics intensityof all work units； logistics routes，distance， and logistics intensity have an influence on layout， which is reflected inthe logistics cost and efficiency . Therefore， SLP can be used in the layout of alogistics center based on logistics product category， logistics quan

42、tity, and otherfactors。2.3 The Main Steps of Layout Based on SLPUnder the guidance of SLP， the first step is to use quantification method to analyzethe logistics relationship and nonlogistics relationship between work units and thento get the composite correlation between work units。 The close degre

43、e relationshipbetween work units determines the distance between work units. According to that，we can arrange its location. Through further amendments and adjustment based onthe move line and other factors, we can get the feasible layout plan。 The specificlayout procedure is as follows.2。3。1 Logisti

44、cs Operation Process and Work Units SettingsThe main activities of the logistics center are purchasing， warehousing, distribution，circulation processing, packing， returning, and so on。 It is necessary to make clearthe main logistics operation process before layout designing。 And then， we analyzethe

45、corresponding P， Q, R， S， and T elements. Based on the analysis， we can dividethe work units.2。3.2 Interrelation Analysis Between Work UnitsIt is reasonable to describe the logistics relationship between work units by logisticsintensity. Logistics intensity is divided into five ranks： A， E， I， O, an

46、d U， asshown in Table 2.1。We can use relationship close degree proposed by R。 Muther to describe thenonlogisticsrelationship between work units。 If two work units have frequent activity，their relationship close degree is high and vice versa。 First, the relationship closedegree is divided into six le

47、vels： A， E， I， O, U, and X, as shown in Table 2。2.Then， list the reason for close relationship (see Table 2。3）。 Using these two kindsof information, we can determine the correlation between work units。 According tothe correlation， the higher the degree is, the closer their distance is。2.3。3 The Comp

48、osite Correlation Analysis BetweenWork UnitsIntegrate the logistics relationship and the non-logistics relationship. According tothe certain weight of each relationship， calculate the composite correlation betweenwork unit i and work unit j (i， j = 1， 2, n and j i).Table 2。1 Logistics intensity rank

49、Table 2.2 The classification of relationship close degreeTable 2。3 The reason forclose relationship2.3。4 Determine the Relative Position of All the Work Unitsand Get the Final Feasible Layout PlanTo design a logistics center layout， the first step is not directly considering the floorspace and shape

50、 of all the work units but the composite correlation between workunits。 If two work units composite correlation is high， their distance is shorter andvice versa. During the layout, according to the composite correlation degree insequence， we locate different work units. If some work units are at the

51、 same level,we determine their relative position by scores。According to the above steps, we can get the preliminary theory position of allwork units， and then, we get the final feasible layout plan through furtheramendments and adjustment based on the actual area, move line， and other factors.2.4 Ca

52、se AnalysisThis paper uses a medicine logistics center as an example to design and analyzeaccording to the characteristics of medicine logistics， move line, and the actualground condition. This paper rationally divides each function areas, solves theevacuating problem, saves land， meets the relevant

53、 regulations, and aims to verifythe feasibility and rationality SLP.2。4。1 Business BackgroundY medicine logistics center located in Jiangsu Province is a thirdparty medicinelogistics enterprise。 It mainly provides a medicine trading platform, stocking，storage， picking, packing, distribution，informat

54、ion processing， and many valueaddedservices for entering enterprises. The logistics center plans to cover 125 unitsof area. Its construction area is 180,000 m2, and its storage area is about80，000 m2。Medicine logistics center has its own characteristics。 Medicines can be dividedinto three types， nam

55、ely the normal drugs at room temperature， some medicinesrequiring refrigeration， and psychiatric drugs。 These three types of drugs must bestored separately using different storage facilities and paid different attention to. Sothis paper divides Y medicine logistics center into several work units as

57、gistics relationship （see Fig。 2.1) and non-logistics relationship（see Fig. 2。2)between work units。2。 Determining the relative importance of logistics relationship and non-logisticsrelationship. For Y medicine logistics center， the weight of two relationships is1:1。3。 Quantifying the logistics inten

58、sity rank and the non-logistics relationship closedegree. Usually, A = 4， E = 3, I = 2， O = 1， U = 0， X = 1。4。 When the number of work units is N， the total matching number can be calculatedusing the following equation： P = N（N 1)/2. Here， N = 9 so P = 36。5。 Calculating the composite correlation bet

59、ween work units （see Table 2.4)。6。 Switching the composite correlation scores （see Table 2.4) to the compositecorrelation close degree rank （see Table 2.5). Then, drawing the compositecorrelation chart （see Fig. 2。3)。7. Determining the relative position of all the work units。 According to Fig。 2.3，

60、thehigher the work unitscomposite correlation is， the shorter their distance is (seeFig. 2.4).8. Analyzing the move line. The move lines of the logistics centers are different fortheir different land areas and logistics products. There are five types， namely I，L， U, O， and S。 Type I is the most simp
