Logistics center is a comprehensive, regional concentration of large quantities of materials, 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 their 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 engineering 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 developed 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.2.2 The Goals, Influencing Factors, and Conditions of Logistics Center Layout2.2.1 The Goals of Logistics Center LayoutAfter 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 cost of material flow, work units1 of high relationship close degree close to each other, simplifying transport routes, shortening.2.2.2 Influencing Factors of Logistics Center Layout Layout design has a significant effect on a production 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:1. The nature and function of a logistics center. Because the nature and function of the logistics 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.2. The 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 the efficient logistics, the basic operation process of a logistics center should be in consideration when layout designing.3. Logistics relationship and non-logistics relationship between work units. Logistics relationship is that there is logistics contact between work units. And interpersonal contact, 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.2.2.3 Application Conditions of SLP in the Layout of Logistics CenterIt is necessary to specify five basic elements, namely 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 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; logistics 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.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 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 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.2.3.1 Logistics 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 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 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 close 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. 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.2.3.3 The Composite Correlation Analysis Between Work UnitsIntegrate 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).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 Position 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 distance is shorter and vice versa. During the layout, according 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 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 to 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 medicine 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 plans 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 psychiatric 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 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. Analyzing the logistics 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-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, 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 (see 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 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 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, packing, distribution, information processing,and many valueadded services.
