Problems solved by technology

The sharp increase in the number of customers has made the queue crowding increasingly serious, and waiting too long will lead to a decline in consumer satisfaction. The current supermarket service window management system mostly adjusts the number of service counters open based on the manager's experience and real-time store traffic. The error rate of the error rate and the randomness of customers arriving at the supermarket will affect the judgment of the manager. At the same time, opening too many service desks will increase the operating cost of the supermarket and reduce the competitiveness of the supermarket. system to solve the above problems

Embodiment 1

[0035] A processing-based supermarket queuing simulation method, the specific steps of the method are as follows:

[0036] Create a queuing model through processing, and use the queuing model to pass the idle probability P of the supermarket service desk 0 Obtain the fullness probability P(n=C) of the supermarket service desk with the service intensity ρ, and determine the opening quantity of the supermarket service desk according to the fullness probability P(n=C);

[0037] For a supermarket checkout service system, the arrival interval of customers and the service time of cashiers to customers are random, so the supermarket checkout service system is a typical random service system, if the arrival interval of customers obeys the parameter λ Negative exponential distribution (thus the number of arrivals serves Poisson distribution), the service time of each customer obeys the negative exponential distribution with parameter μ, and the arrival of customers is independent of th...

Embodiment 2

[0058] The same invention provides a system corresponding to a processing-based supermarket queuing simulation method, the system includes a model building module, a data analysis module and a service desk opening module;

[0059] The model building module establishes the queuing model through processing, and the data analysis module uses the queuing model to pass the idle probability P of the supermarket service desk. 0 Obtain the fullness probability P (n=C) of supermarket service desk with service intensity ρ, and service desk opening module determines the opening quantity of supermarket service desk according to fullness probability P (n=C);

[0060] For a supermarket checkout service system, the arrival interval of customers and the service time of cashiers to customers are random, so the supermarket checkout service system is a typical random service system, if the arrival interval of customers obeys the parameter λ Negative exponential distribution (thus the number of a...

Embodiment 3

[0081] On the basis of Embodiment 2, first generate 50 customers with a Poisson distribution whose arrival interval obeys the parameter λ=0.6 through Python, and each customer generates a corresponding required service time that obeys the exponential distribution with the parameter μ=0.4, and Output the corresponding service desk;

[0082] Use the waiting time calculation module to calculate the average waiting time of customers queuing in the system:

[0083]

[0084] Use the stay time calculation module to calculate the average stay time of customers in the system:

[0085]

[0086] Compared with the queuing model of two service desks and two queues under the same situation of unlimited customer capacity, the average waiting time and average stay time of customers in the system will increase by about 4.286 unit time. Obviously, in this case, the single-queue model customers Experience satisfaction is better.

Abstract

The invention discloses a supermarket queuing simulation method and system based on proceeding, and belongs to the field of service systems. The supermarket queuing simulation method based on processing comprises the following specific steps: 1, carrying out supermarket queuing simulation on the basis of processing; establishing a queuing model through programming, obtaining a full-load probability P (n = C) of a supermarket service desk through the idle probability P0 and the service intensity rho of the supermarket service desk by utilizing the queuing model, and determining the opening number of the supermarket service desk according to the full-load probability P (n = C). By using the method or the system, the established queuing model can simulate the arrival time of the customer andthe time of the required service, and further the opening number of the service desks can be selectively adjusted by the management personnel, the accuracy of the simulation result is higher, the effect is better, the supermarket operation cost is effectively controlled, average queuing time of the customers is reduced, shopping service satisfaction of the customers is improved, and competitiveness of the supermarket is improved.

Description

technical field [0001] The invention discloses a processing-based supermarket queuing simulation method and a system thereof, and relates to the technical field of service systems. Background technique [0002] With the improvement of living standards, large supermarkets have penetrated into our lives at an unprecedented speed. The major supermarkets have produced fierce competition, and these competitions are not only the competition of product quality, but also the competition of service. Among the quality of service, the most important thing is the queuing checkout system. [0003] As the largest developing country in the world, my country is also the country with the largest population. Under the condition of limited resources, the per capita share is very low. With the rapid increase of the population, in China, population pressure has affected many aspects such as employment, transportation, and commodity resources. The sharp increase in the number of customers has ...
