Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
The site selecting method of the present embodiment provides a kind of Cold Chain Logistics home-delivery center based on goods damage, it is as shown in fig. 1, described
Method includes:
Step S100, alternative point of several addresses as home-delivery center is chosen in target area；
Step S200, determine supplier to each home-delivery center and each home-delivery center to the transport item of each demand point
Part；
Step S300, goods damage cost is determined according to traffic condition, by the logistics assembly including the goods damage cost
Originally it is input in mathematical model, and site selection model is constructed as condition lower than predetermined value using Logistics Total Cost；
Step S400, the site selection model is solved using simulation software, exports the addressing result of home-delivery center.
The network of Cold Chain Logistics is generally divided into three-level, including several suppliers, home-delivery center and demand point.Fresh product
Freezer first near supplier is pre-chilled, and then carries out long-distance Refrigerated Transport toward home-delivery center by large-scale refrigerator car,
After home-delivery center carries out processing transfer, cold-storage delivery finally is carried out from home-delivery center toward demand point.Due to the life of different categories
The requirement that fresh product transports the storage and transportations such as temperature, humidity, time is different, therefore the present invention is just for the fresh product of certain category,
Its Cold Chain Logistics network of research and establishment.And the building of Cold Chain Logistics network mainly considers following problems: how to determine home-delivery center
Quantity and position and supplier to home-delivery center, home-delivery center to demand freight volume so that the object of Cold Chain Logistics running
It is minimum to flow totle drilling cost.Here, the Logistics Total Cost of Logistics Operation includes the construction cost of home-delivery center, transfer cost, transport
The refrigeration cost of delivery process and transportation cost, the goods damage cost of fresh product.Meanwhile in the logistics network for constructing fresh product
When, it be in view of factors such as the availability of supplier, the product demand in market, the storage capacitys of home-delivery center.As it can be seen that cold chain
The addressing of home-delivery center has with many factors and contacts in the presence of close in logistics network.
Specifically, multiple addresses are chosen on the map of target area as the alternative of home-delivery center first in the present embodiment
Point, since fresh product cargo is during transit link, if traffic condition is relatively good, goods damage situation is relatively fewer, at present
Goods damage occur mainly in dispatching link.Therefore it needs to be determined that supplier is to each home-delivery center and each matches in the present embodiment
Send center to the traffic condition of each demand point.Preferably, traffic condition specifically includes that supplier between each home-delivery center
Haulage vehicle energy consumption for cooling, and dispatching stage incubator in soaking time.After determination knows traffic condition, just
The goods damage situation in transport and delivery process that can determine cargo, so that it is determined that goods damage cost out.
In the present embodiment, the goods damage cost of cargo needs to consider the rate that kinds of goods addle；The rate that the kinds of goods addle
It is related with the soaking time in dispatching stage incubator.Specifically, due to having addled since fresh product is in storage and transport process
Part other intact parts can be impacted, so the rate that kinds of goods addle can be more next with the growth of storage and transportation time
Faster, the growth of exponential type can be presented in the rate that addles.In the problem of fresh product cold chain transportation is studied, Allan Buddhist nun is generallyd use
This black formula (Arrhenius equation) indicates the rates that addles of kinds of goods, as follows: Q (t)=Q0e-θt,
Wherein Q0It is quality when cargo does not addle also at the beginning, Q (t) is the quality of cargo t moment, and θ indicates transport way
The velocity coefficient that addles of middle cargo.
Further, due to having certain Insulation in dispatching link, goods damage will not be generated early period.But with the time
Passage, after ice melting in incubator, cargo will addle.Therefore, in order to more precisely embody the corruption of cargo
Bad situation assumes that the time ice melting in dispatching stage incubator is t'(soaking time in the present embodiment).To the rate that addles
Coefficient θ segmentation consideration, such as:
According to above-mentioned formula, when the time time t of cargo transport ice melting in incubator is within t', cargo
Addle velocity coefficient θ be 0, i.e. cargo does not addle substantially.And melt when the time t of cargo transport is greater than ice cube in incubator
When the time of change is t', then the velocity coefficient θ that addles of cargo is a, then according to the formula of the above-mentioned rate that addles it is found that cargo can be sent out
Life is significantly addled, and as the time elapses again backward, the degree of addling can be more serious.
The present embodiment obtains the goods damage situation of cargo based on the rate that addles of cargo, and obtains goods damage cost.It is selected in building
Goods damage cost is also taken into account when the model of location, to construct more reasonable site selection model.
Further, in this embodiment site selection model be to be constructed lower than predetermined value as condition using Logistics Total Cost.
It preferably, is that model is constructed using the minimum condition of Logistics Total Cost in practical application.In addition to packet in the Logistics Total Cost
Include other than goods damage cost, further includes: freight, the energy consumption for cooling of transport vehicle amount, food goods damage cost, heat preservation ice bag refrigeration at

With home-delivery center's construction cost and storage refrigeration cost.After constructing the site selection model, using simulation software to institute
It states site selection model and is programmed resolving, find out globally optimal solution, which is the addressing result of home-delivery center.Preferably,
Using Lingo software, (Lingo software can be used for solving Non-Linear Programming, and execution speed is very fast, be to solve in the present embodiment
The optimal selection of Optimized model) site selection model is solved.For example, alternative logistics distribution center address has 7,3 confessions
Quotient is answered to supply for it, 40 clients need product (i.e. demand point is 40), need to select 3 alternative points and match to establish logistics
Center is sent, the setting of relevant parameter is as follows:
Haulage stage unit cost h=0.3；Dispense stage unit transportation cost h'=0.5；When haulage stage unit
Between vehicle refrigeration energy consumption cost w=39.2；Fixed vehicle speed v=60 of the supplier to home-delivery center；Home-delivery center arrives demand point
Fixed vehicle speed v'=20；The specified cargo dead-weight a=200 of bulk transport vehicle；The capacity b=10 of dispatching stage crisper；Fresh-keeping ice
The cost d=10 of bag；The monovalent q=50 of fresh product；It addles velocity coefficient θ=0.3；Total customer demand is 471, specific every
The customer demand of a client is set at random.Parameter is substituted into the site selection model of building, recycles Lingo software to the example
It is solved, by 17068 step iteration, show that addressing result is 1,3, No. 4 alternative point, and minimum Logistics Total Cost is
5137.6。
Further, in order to understand influence of each parameter to Cold Chain Logistics Location of Distribution Centre in model, we are to model
In parameter carry out verifying analysis.Specifically, in the present embodiment using simulation software to the rate that addles in the site selection model
Soaking time in coefficient, customer demand, transport vehicle cargo dead-weight and dispatching stage incubator carries out sensitivity analysis, obtains
The soaking time to addle in velocity coefficient, customer demand, transport vehicle cargo dead-weight and dispatching stage incubator is to addressing result
Influence.It makes a concrete analysis of as follows:
(1) spoilage rate coefficient θ is analyzed
Since the rate difference that addles of variety classes kinds of goods, such as the freezing aquatic product product rate that addles are very fast, the agricultural productions such as vegetables
The product rate that addles is slower.Spoilage rate coefficient θ is now taken into different values, to analyze the variation with spoilage rate coefficient θ, logistics
The situation of change of totle drilling cost.To obtain influence of the spoilage rate coefficient to fresh product delivery center location strategy.According to this
Text it is assumed that spoilage rate coefficient θ will lead to the loss of fresh product in transportational process.Therefore spoilage rate coefficient θ is to fresh
The Location of Distribution Centre of product Cold Chain Logistics has important influence, as shown in table 1.
Table 1 addles influence of the velocity coefficient θ to Location of Distribution Centre
As shown in Table 1, the type of cargo, the difference of traffic condition, caused velocity coefficient θ variation of addling, with loss
Rate is continuously increased, and the totle drilling cost of Location of Distribution Centre is also constantly becoming larger.When the velocity coefficient θ that addles is 0.15 < θ < 0.25, match
Cost (removing goods damage) is sent to be gradually increased.As spoilage rate coefficient θ > 0.25, distribution cost (removing goods damage) is begun to decline, and is transported
Defeated cost is begun to ramp up, and the average dispatching distance of unit commodity is reduced, and the average transportation range of unit commodity increases, and supplier arrives
Home-delivery center's distance reduces, and the addressing of home-delivery center is closer to client.And when addressing scheme is identical (such as addressing result be 1,
4,7 when), goods damage cost with spoilage rate coefficient θ increase and increase.
(2) sensitivity analysis of customer demand
The demand of a client not instead of definite value, the variation of fluctuation is presented with the difference in month.Now setting is each
The customer demand of client's different times sums the demand of each client to obtain total customer demand of home-delivery center, then
Variation of the analysis with the total customer demand of home-delivery center, the situation of change of Location of Distribution Centre position, as shown in table 2.
Influence of 2 customer demand of table to Location of Distribution Centre
As can be drawn from Table 2, with the increase of customer demand, the addressing of home-delivery center can select closer apart from client
Alternative point.
(3) sensitivity analysis of transport vehicle cargo dead-weight
According to the above solving result, the present embodiment has chosen at present the refrigerator car of more typical different size model on the market
It is compared, analyzes its influence to Logistics Total Cost.Related data and solving result are shown in Table 3, table 4.
3 refrigerator car data decimation of table
Influence of the 4 transport vehicle cargo dead-weight of table to Logistics Total Cost
It can be seen from Table 4 that being suitable for being transported using small-sized refrigerator car, at this time when client's aggregate demand is smaller
