2. Tobacco commercial enterprises can build a variety of forms and scale of logistics distribution system, such as the distribution center through the cart distribution of goods to the transfer station, the distribution center and the transfer station respectively through the car distribution to the household mode. At present, the division of China's tobacco logistics distribution area is mainly based on administrative divisions. When setting up distribution nodes (secondary distribution station and determining the service scope of secondary distribution station), the distribution scope of secondary distribution station is not determined according to the information provided by GIS system. Therefore, some distribution centers (or transfer stations) have the problems of high logistics operation cost, more application personnel, more vehicles and low loading rate, which lead to the obvious unreasonable phenomenon when dividing the distribution lines in the logistics area, and finally lead to the aggravation of the sorting task and increase the labor cost
taking the distribution cost as the objective function, this paper establishes a mathematical programming model of logistics distribution area division, and proposes an efficient algorithm to determine the location and distribution scheme of distribution center and transfer station through the solution of the model, so as to determine their respective distribution areas< According to the current situation of tobacco distribution center construction in China, it can be determined that a city (including subordinate towns) only has one tobacco distribution center, and the city can be divided into several economic regions, Select several economic regions to set up transfer stations (the number is less than the number of economic regions)
therefore, the modeling idea of this paper is to break the ownership of administrative regions, divide the original distribution regions into several economic regions, and the distance between regions can be calculated by their center distance. The transportation cost of various schemes, the construction and operation cost of transfer station are calculated in detail, and the corresponding mathematical programming model is established
2.2 assumption and variable definition
it is assumed that the tobacco distribution area is composed of M counties (or urban areas) and N towns (or townships, suburbs, etc.), and the tobacco distribution center has been built in a certain urban area, so it is necessary to set up several transfer stations (less than m-1) among the remaining M-1 counties (or urban areas). The number of tobacco retail households and tobacco demand in each region are known
definition of parameters and variables:
decision variables or 1,; At that time, it was said that the transfer station would be set up in the region. At that time, it was said that the transfer station would not be set up in the region
distribution area demand variable: the demand of the first distribution unit
delivery transfer (distribution) capacity of transfer station (including distribution center): the distribution capacity of the first distribution unit
distribution relationship variable of each region: indicates that the point is a distribution center or transfer station and distributes to the region; It means that the point is not a distribution center or a transfer station or does not distribute to the distribution area
the variable is the output from the first distribution unit to the second distribution unit in the distribution area
is the loading capacity of trolley, box / car
refers to the loading capacity of large vehicles, in cases / vehicles
fuel consumption for 100 km, L / 100 km
the fuel consumption of the car is 100 km, L / 100 km
is the price of diesel oil, yuan / L
is the annual maintenance fee of the cart, yuan / year
is the annual maintenance cost of the car, yuan / year
is the distance from the center of the region to the center of the region (for convenience of calculation, the position coordinates of the center of each region can be taken)
is the distance from the distribution center to the regional center< br /> λ It is the transfer capacity coefficient (constant) of the transfer station
2.3 model establishment
based on the above definition, the corresponding cost items can be expressed and constitute the overall objective function
the above cost items can be defined as:
(a) the distribution cost of part of the logistics area of the distribution center car distribution
(b) the distribution fee and annual maintenance fee of the cart from the distribution center to the transfer station
(c) car distribution cost and car annual maintenance cost of transfer station
(d) the cost of building a transfer station
according to the actual operation of tobacco, the following constraints can be determined:
(a) when the distribution unit is a distribution center or transfer station, the demand is equal to the distribution volume
(b) ensure that the total demand of the distribution unit is equal to the total distribution volume
(c) ensure that there is only one distribution unit for any ordinary unit
(d) ensure that the distribution volume of the distribution unit is equal to the sum of the demands of the corresponding ordinary units
(E) the distribution volume of the distribution center or transfer station is equal to the sum of the demand of the ordinary unit and the unselected transfer station
(f) ensure that the distribution capacity is equal to the demand
3 the algorithm for solving the distribution area partition model
Step 1: generate the initial population according to the number of distribution centers and transfer stations for genetic coding
Step 2: calculate the fitness of the population
Step 3: the combination of optimal selection and roulette selection is used to delete and chromosomes to generate new species
Step 4: cross the population with crossover probability PC to check whether the constraint conditions are met and generate new species
Step 5: the population is mutated with mutation probability PM to check whether the constraint is met and form a new species group
Step 6: judge whether the termination rule is satisfied: when the maximum number of iterations or the optimal solution is reached, stop if the requirements are met, otherwise turn to step 3
Step 7: decode the calculation results
Step 8: select all the calculated results after decoding and compare them to select the one with the smallest result.

The most simple and reliable method: query from the bar code of cigarettes

1, Find this bar code

< RRRRR}

other methods

1. identify from transparent paper

< / OL >

transparent paper is a kind of cigarette film, which is the packaging material of cigarette package and small package, generally BOPP film, is a kind of special film


real smoke: from the appearance, transparent paper has high transparency, plastic film is thin and bright, and the surface luster is good. When you touch it with your hand, it feels smooth, soft and elastic, and the film is thin. It is very flat and tight with the inner master paper

fake cigarette: generally, the transparent paper is poor in ground, and the transparency and smoothness are not enough. What we use is general film, which is thicker, the brightness is not enough, and the inner packaging paper is also uneven. If we look at the cigarette box through the film, we will feel that the transparency is poor. If we touch and push it, we will feel that the film is thick and hard

Real tobacco was identified from cut tobacco: the cut tobacco had natural color, good gloss and oily feeling. Because the stem was not easy to burn, it was easy to extinguish, so the regular manufacturer puffed the stem ring proction

fake tobacco: cut tobacco is cigarette waste or untreated inferior procts. In order to confuse consumers, sulfur fumigation and hydrogen peroxide are generally used for decolorization. Although the cut tobacco appears yellow and bright, careful observation will find that the color of cut tobacco is dark and the surface is rough

To identify the real smoke from its combustibility: it has good combustibility, and can burn still after ignition without flameout

fake cigarette: on the one hand, because the proportion of chlorine and potassium in cut tobacco is not coordinated, the combustibility of cigarette is affected; On the other hand, because the stem in the fake cigarette is not puffed, and there are stem sticks and stem blocks in it, there is often flameout phenomenon

4. Identify from the ash

after general consumers smoke, they think it is good smoke when they see the ash is whiter. In fact, this is also a misunderstanding. In fact, the color of soot is affected by the drying degree of tobacco leaves. When the tobacco leaves are dry, the soot will be gray white after burning, otherwise it will be black and difficult to smoke

judging from the ash, we should observe whether there are more stems in the cut tobacco ring combustion, when more stems appear, the cigarette may have false

5. compares aroma and taste to

true smoke: all grades of tobacco are generally in line with their corresponding grade standards. The smell of genuine tobacco has a open package aroma, and the natural aroma and flavor of tobacco are soft and pleasant. p>

fake cigarettes: it is impossible for counterfeiters to consider the taste problem. Although the packaging of fake cigarettes is various, the cut tobacco and the taste of fake cigarettes are the same. After opening the package, there was obvious discomfort and irritation in the nose. Appearance: the package of real cigarette is square and smooth, and the laps are neat, clear and smooth. The package of small box and strip box of fake cigarette is irregular, with rough and dim lap

5. 1、 What are the departments of tobacco distribution? What kind of process do they run
answer: 1. The Tobacco Distribution Department is the logistics center (prefecture level tobacco company)
2. The storage and Distribution Department of the logistics center (tobacco factory arrival) scans the code before entering the warehouse → the order department collects the order according to the inventory information (telephone sales visit) → the storage and Distribution Department of the logistics center scans the code after leaving the warehouse according to the order information → all the outgoing cigarettes enter the sorting workshop for sorting One line one yard sorting work → logistics center delivery department will deliver cigarettes to retail customers (cigarettes in other counties should be distributed at three levels, prefecture level tobacco companies → cigarette marketing department in other counties → retail customers)

Second, is tobacco distribution like government departments? If there are provincial, municipal and county levels, is there district level? Are they allocated uniformly at the provincial level to the municipal level, and then at the municipal level to the county level, or to the districts under their jurisdiction? What level of distribution center do wholesalers and retailers take their tobacco from? City level, county level, district level
A: 1. District level
2. Municipal companies can directly place orders with tobacco factories to organize the source of goods (according to the sales plan issued by provincial companies)
3. Tobacco wholesalers are only prefecture level tobacco companies, and any other organizations and indivials are not wholesalers, so tobacco companies can only order from tobacco factories; All other cigarette retailers should order from prefecture level and municipal tobacco companies, and the tobacco companies are responsible for delivering cigarettes to their customers< Third, is the price of tobacco distribution fixed or will it change according to the size of the seller
A: the selling price of cigarettes is strictly uniform and will not change with the size of retail customers
