5、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 移動線及其他因素進一步修正和調(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，對其進行了設(shè)計、分析、評價，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2.1引言自進入二十一世紀(jì)，物流產(chǎn)業(yè)在中國得到了迅速的成長，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，它是一個中介于生產(chǎn)和銷售之間的的企業(yè)，整合了 商品流，物流，信息流和

6、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。首先，人們用他們的經(jīng)驗和感覺去設(shè)計物流中心。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)驗是很難設(shè)計物流中心的。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，以及一些更先進的設(shè)計方法已經(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。2.2目標(biāo)，影響因素和物流中心布局的條件2

7、.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，簡化運輸路線，縮短相似工作單位之 間的距離，避免迂回運輸?shù)鹊取?.2.2物流中心布局的影響因素布局設(shè)計對生產(chǎn)性能或服務(wù)系統(tǒng)的性能有顯著影響。對于一個物流中心，其 布局對物流，信息流，物流運作效率，成本，以及整個系統(tǒng)的安全性有直接影響。 所以，對物流中心布局的影響因素如下：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。物流中心的規(guī)模和布局也不一樣。據(jù)其核心

8、功能，物流中 心有三種類型：中轉(zhuǎn)物流中心，倉儲物流中心，配送物流中心。物流中心的基本操作流程。物流中心的主要活動是采購、倉儲、配送、流 通加工、包裝、返回等。其操作過程對人員，設(shè)備和物流路線有影響。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)時間或技術(shù)）。 前兩個基本要素是最重要的。不

9、同的物流產(chǎn)品對倉儲、裝卸、物流等物流活動有 不同的要求。最終，它會導(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)，決定了物流運作的時間。物流中心的工作數(shù)量反映所有單位的物流 強度；物流路線、距離、和物流強度的影響，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)這個我們可以安排它的位置。通過進一步的 修改和調(diào)整，根據(jù)移動線路等因

10、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是采購、倉儲、配送、流通加工、包裝、返回等。 在規(guī)劃設(shè)計之前，必須明確物流的主要運作流程。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)分析用物流強度來描述工作單位之間的物流關(guān)系是合理的。物流強度分為五個行 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。如果兩個單位有活動頻繁，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等級：A，E，

11、I，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)每個關(guān)系的一定的權(quán)重，計算工作單元i和工作單位j （i, j = 1,2,n和j豐i）之間的復(fù)合相關(guān)性。表2.1物流強度等級物流強度標(biāo)志物流路線的比例（）物流量（%）絕對重要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絕對重要2-5E極其重要3-10I重要5-15O一般重要10-25U不重要45-80X

13、的布局計劃通過進一步修改和調(diào)整根據(jù)實際面積，移動，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、移動路線、實際地面條件，設(shè)計 并分析其特點。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，是一個第三方醫(yī)藥物流企業(yè)。它主要提供藥品 交易平臺，采購、儲存、揀選、包裝、配送、信息處理、和許多進入企業(yè)的增值 服務(wù)。物流中心計劃覆蓋125個區(qū)域的單位。其建筑面積為180000平方米，倉 儲面積約為80000平方米。醫(yī)藥物流中心有其自身的特點。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

14、品。這三種類型的藥物必須分開存放， 使用不同的存儲設(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 個工作單位。（1）工作區(qū)；（2）到達分揀區(qū)；（3）自動存儲/檢索系統(tǒng)（AS / RS）； （4）冷藏區(qū)；（5）精神藥品儲存區(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)。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。測定的物流關(guān)系和非物流關(guān)系的相對重要性。Y的醫(yī)藥物流中心，兩個關(guān) 系的權(quán)重為1： 1。量化物流強度等級和非物流關(guān)系的緊密程度。通常情況下，A = 4, E = 3,I = 2， O = 1，U = 0， X = -1。

15、當(dāng)?shù)墓ぷ鲉卧臄?shù)量是N，可以使用以下等式來計算的總匹配數(shù)：P = N （N - 1）/ 2。在這里，N = 9 SOP = 36。計算工作單位之間的復(fù)合關(guān)系（見表2.4）。切換復(fù)合相關(guān)分?jǐn)?shù)（見表2.4）到復(fù)合關(guān)聯(lián)密切程度等級（參見表2.5）。 然后，繪制復(fù)合相關(guān)圖表（參見圖2.3）。確定所有的工作單位的相對位置。根據(jù)圖2.3，工作單位的復(fù)合物的相關(guān) 性越高，它們的距離越短（見圖2.4）。分析移動線。物流中心的移動線因不同的土地和物流產(chǎn)品而不同。有五種 類型，即I, L, U, O和 S。I型是最簡單的，它適用于矩形物流中心的入口到出口。S 型是最復(fù)雜的，很適用于安排一個很長的物流路線。Y醫(yī)藥物

16、流中心是接近長方 形。Y醫(yī)藥物流中心的主要活動是備貨，倉儲，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)系序號11工作區(qū)2到達分博區(qū)3AS / RS4冷藏區(qū)56揀貸區(qū)包裝加工區(qū)3駛堇和發(fā)布9服務(wù)區(qū)寸aJn一01工作區(qū)L.

28、c industry in China has been rapidly growing up and the number of logistics centers has increased dramatically.Many large- and medium-sized cities across the country are planning to set up logistics centers. Logistics center is a comprehensive, regional concentration of large quantities of materials

29、, and it is an intermediary between production and marketing enterprises, integrating commodity flow, logistics, information flow, and cash flow . The reasonable layout of logistics centers has taken more and more attention, and it is also the research focus of many scholars.At first, people use the

30、ir experience and feeling to design the logistics centers. In the 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, with the integration development of the diverse discipline, the system engine

31、ering concept and system analysis method have been used in layout planning , and some more advanced design methods have gradually emerged. One of the most representative methods is systematic layout planning (SLP) proposed by American R. Muther in 1961. Study on facilities layout problem is develope

32、d from qualitative stage to quantitative stage on the basis of SLP . SLP is also widely applied to various production systems and service systems . Finally, it improves to move line SLP.The Goals, Influencing Factors, and Conditions of LogisticsCenter LayoutThe Goals of Logistics Center LayoutAfter

33、determining the location of a logistics center, the overall goal of logistics center layout is to make the personnel, equipment, and material space in the logistics activity process be in the most appropriate allocation and the most effective combination . The specific goals can be the minimum total

34、 cost of material flow, work units1 of high relationship close degree close to each other, simplifying transport routes, shortening.Influencing Factors of Logistics Center LayoutLayout design has a significant effect on a production performance or service system performance.For a logistics center, i

35、ts 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 of a logistics center. Because the nature and function of the logistic

36、s centers is different, it is different to choose equipment type and quantity. The size and layout of logistics centers are also not the same.According to its core function, the logistics center has three types: transit logistics center, storage logistics center, and distribution logistics center.Th

37、e basic operation process of a logistics center. The main activities of the logistics center are purchasing, warehousing, distribution, circulation processing, packing, returning, and so on . The operation process has an influence on the move line of personnel, equipment, and material. To realize th

38、e efficient logistics, the basic operation process of a logistics center should be in consideration when layout designing.Logistics relationship and non-logistics relationship between work units. Logistics relationship is that there is logistics contact between work units. And interpersonal contact,

39、 administrative affairs, and other activities can be expressed as non-logistics relationship between work units. Work units of high relationship close degree should be close to each other.Application Conditions of SLP in the Layout of Logistics CenterIt is necessary to specify five basic elements, n

40、amely P (logistics products), Q (logistics quantity), R (logistics routes), S (service sectors), and T (logistics operation time or technology) before applying SLP to logistics center layout. The first two basic elements are the most important. Different logistics products have different demands on

41、storage, loading, and other logistics activities. Ultimately, it leads to different logistics routes. What is more, using different logistics equipment and technology determines logistics operation time. The work quantity of the logistics center reflects the logistics intensity of all work units; lo

42、gistics routes, distance, and logistics intensity have an influence on layout, which is reflected in the logistics cost and efficiency . Therefore, SLP can be used in the layout of a logistics center based on logistics product category, logistics quantity, and other factors.The Main Steps of Layout

43、Based on SLPUnder the guidance of SLP, the first step is to use quantification method to analyze the logistics relationship and non-logistics relationship between work units and then to get the composite correlation between work units. The close degree relationship between work units determines the

44、distance between work units. According to that, we can arrange its location. Through further amendments and adjustment based on the move line and other factors, we can get the feasible layout plan. The specific layout procedure is as follows.Logistics Operation Process and Work Units SettingsThe mai

45、n activities of the logistics center are purchasing, warehousing, distribution,circulation processing, packing, returning, and so on. It is necessary to make clear the main logistics operationprocess before layout designing. And then, we analyze the corresponding P, Q, R, S, and T elements. Based on

46、 the analysis, we can divide the work units.Interrelation Analysis Between Work UnitsIt is reasonable to describe the logistics relationship between work units by logistics intensity. Logistics intensity is divided into five ranks: A, E, I, O, and U, as shown in Table 2.1.We can use relationship clo

47、se degree proposed by R. Muther to describe the nonlogistics relationship between work units. If two work units have frequent activity, their relationship close degree is high and vice versa. First, the relationship close degree is divided into six levels: A, E, I, O, U, and X, as shown in Table 2.2

48、.Then, list the reason for close relationship (see Table 2.3). Using these two kinds of information, we can determine the correlation between work units. According to the correlation, the higher the degree is, the closer their distance is.The Composite Correlation Analysis Between Work UnitsIntegrat

49、e the logistics relationship and the non-logistics relationship. According to the certain weight of each relationship, calculate the composite correlation between work unit i and work unit j (i, j = 1, 2,., n and j / i).closeTable 2.1 Logistics intensity rankinteitvty rankl 碾isficE mutt礦1 jifiities

52、t PlanTo design a logistics center layout, the first step is not directly considering the floor space and shape of all the work units but the composite correlation between work units. If two work units composite correlation is high, their distance is shorter and vice versa. During the layout, accord

53、ing to the composite correlation degree in sequence, we locate different work units. If some work units are at the same level,we determine their relative position by scores.According to the above steps, we can get the preliminary theory position of all work units, and then, we get the final feasible

The logistics center plans to cover 125 units of area. Its construction area is 180,000 m 2, and its storage area

57、is about 80,000 m2.Medicine logistics center has its own characteristics. Medicines can be divided into three types, namely the normal drugs at room temperature, some medicines requiring refrigeration, and psychiatric drugs. These three types of drugs must be stored separately using different storag
