2、 . Therefore, SLP can be used in the layout of a logistics center based on logistics product category, logistics quantity, and other factors.2.3 The Main Steps of Layout Based on SLPUnder the guidance of SLP, the first step is to use quantification method to analyze the logistics relationship and no
3、n-logistics relationship between work units and then to get the composite correlation between work units. The close degree relationship between work units determines the distance between work units. According to that, we can arrange its location. Through further amendments and adjustment based on th
4、e move line and other factors, we can get the feasible layout plan. The specific layout procedure is as follows.2.3.1 Logistics Operation Process and Work Units SettingsThe main activities of the logistics center are purchasing, warehousing, distribution,circulation processing, packing, returning, a
5、nd so on. It is necessary to make clear the main logistics operation process before layout designing. And then, we analyze the corresponding P, Q, R, S, and T elements. Based on the analysis, we can divide the work units.2.3.2 Interrelation Analysis Between Work Units西华大学建设与管理工程学院本科生毕业设计英文翻译 It is r
6、easonable 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 close degree proposed by R. Muther to describe the nonlogistics relationship between work units
7、. 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. Then, list the reason for close relationship (see Table 2.3). Using these two kinds of inf
8、ormation, we can determine the correlation between work units. According to the correlation, the higher the degree is, the closer their distance is.2.3.3 The Composite Correlation Analysis Between Work UnitsIntegrate the logistics relationship and the non-logistics relationship. According to the cer
9、tain weight of each relationship, calculate the composite correlation between work unit i and work unit j (i, j = 1, 2, n and j i).Table 2.1 Logistics intensity rankTable 2.2 The classification of relationship close degreeTable 2.3 The reason for close relationship2.3.4 Determine the Relative Positi
10、on of All the Work Units and Get the Final Feasible Layout 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 dist
11、ance is shorter and vice versa. During the layout, according to the 西华大学建设与管理工程学院本科生毕业设计英文翻译 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
12、preliminary theory position of all work units, and then, we get the final feasible layout plan through further amendments and adjustment based on the actual area, move line, and other factors.2.4 Case AnalysisThis paper uses a medicine logistics center as an example to design and analyze according t
13、o the characteristics of medicine logistics, move line, and the actual ground condition. This paper rationally divides each function areas, solves the evacuating problem, saves land, meets the relevant regulations, and aims to verify the feasibility and rationality SLP.2.4.1 Business BackgroundY med
14、icine logistics center located in Jiang su Province is a third-party medicine logistics enterprise. It mainly provides a medicine trading platform, stocking, storage, picking, packing, distribution, information processing, and many valueadded services for entering enterprises. The logistics center p
15、lans to cover 125 units of area. Its construction area is 180,000 m2, and its storage area 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 psy
16、chiatric drugs. These three types of drugs must be stored separately using different storage facilities and paid different attention to. So this paper divides Y medicine logistics center into several work units as follows.(1) office area; (2) arrival and sorting area; (3) automatic storage/retrieval
17、 system(AS/RS); (4) cold storage; (5) psychiatric drugs storage; (6) picking area; (7)packing and processing area; (8) gathering and distribution; and (9) service sectors.2.4.2 Application of SLP1.

18、een work units.2. Determining the relative importance of logistics relationship and non-logistics relationship. For Y medicine logistics center, the weight of two relationships is 1:1.3. Quantifying the logistics intensity rank and the non-logistics relationship close degree. Usually, A = 4, E = 3,
19、I = 2, O = 1, U = 0, X = 1.4. When the number of work units is N, the total matching number can be calculated using the following equation: P = N(N 1)/2. Here, N = 9 so P = 36.5. Calculating the composite correlation between work units (see Table 2.4).6. Switching the composite correlation scores (s
20、ee Table 2.4) to the composite correlation close degree rank (see Table 2.5). Then, drawing the composite correlation chart (see Fig. 2.3).7. Determining the relative position of all the work units. According to Fig. 2.3, the higher the work units composite correlation is, the shorter their distance
21、 is (see Fig. 2.4).8. Analyzing the move line. The move lines of the logistics centers are different for their different land areas and logistics products. There are five types, namely I,L, U, O, and S. Type I is the most simple, and it is suitable for the rectangular logistics center whose entrance
22、 is to the exit. Type S is the most complex, and it is suitable to arrange a long logistics route. Y medicine logistics center is nearrectangular.The main activities of Y medicine logistics center are stocking,storage, picking, 西华大学建设与管理工程学院本科生毕业设计英文翻译 packing, distribution, information processing,a
23、nd many valueadded services. So this paper intends to design Y medicine logistics center combining type L with type U (see Fig. 2.5).9. The final feasible layout plan. After adjustment, the final layout plan is shown in Fig. 2.6.Table 2.4 The composite correlation between work unitsRelationship clos

27、logistics relationship and non-logistics relationship. So the final feasible layout plan is comprehensive. What is more, the main activities of Y medicine logistics center are stocking, storage, picking, packing, distribution,information processing, and many value-added services. Its storage area is
28、 about 80,000 m2. Therefore, we put the three warehouses nearly in the middle considering the warehouse layout priority principle. This is helpful for the quick contact with the other circumjacent area, and this helps to improve the logistics centers operational efficiency. At the same time, the cla
29、ssification of warehouses contributes to the different storage requirements of different customers. And there is enough space for adjustment, greatly improving the flexibility of the storage system. The designed move line of Y medicine logistics center, combining both the layout of work units and th
30、e principle of avoiding circuitous transportation, can well ensure smooth logistics activities. Different storages can also use different move lines.西华大学建设与管理工程学院本科生毕业设计英文翻译 2.5 ConclusionThis paper focuses on the layout of the logistics center, proposes the use of SLP to design the layout of the lo
31、gistics center, and adds to the move line analysis.Through the analysis of this paper, the main conclusions are as follows.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 th
32、e most effective combination.At the same time, the main influencing factors of logistics center layout are the nature, function, basic operation process of a logistics center, logistics relationship, and non-logistics relationship between work units. Through the case analysis, after making clear the
33、 P, Q, R, S, and T elements, it is feasible and reasonable to use SLP in the layout of a logistics center.It provides a good reference for other logistics center layout problem. It is necessary to point out some limitations and shortages. When drawing the relative position of the work units figure,
34、people have to constantly adjust and amend the plan in order to meet the corresponding condition. What is more, different designers way of solving conflicts may lead to different design plans. How to use the computer simulation technology to compare SLP layout plan with other plans is one of our fut
