Description
Technical Field
The invention relates to the technical field of logistics distribution, in particular to a cold chain logistics distribution method, a system and equipment.
Background
The logistics distribution is generally divided into three hierarchical systems. The first layer is the international and domestic long-distance logistics fast delivery, the second layer is the trunk distribution, and the third layer is the regional distribution. The same city distribution belongs to the level of regional distribution, provides special vehicle distribution service for single or multiple cargoes in a specified city range at fixed time and fixed quantity for customers, and aims to solve the problem of 'last kilometer' of logistics.
In the third-level distribution of the related art, some of the distribution systems employ a store distribution system or a store self-picking system, and other of the distribution systems employ a self-picking point or a self-picking cabinet system, and a receiver receives a notification and then self-picks up the product. But neither of these solutions meets the cold chain stream requirements of fresh and like products. Because stores and self-lifting cabinets and the like in the prior art only support common goods, the temperature requirements of the goods requiring cold chain logistics such as fresh goods and the like are high, if the two schemes are adopted to solve the problem of the distribution of the cold chain logistics, the construction cost is very high no matter the store meeting the requirements is built or the self-lifting cabinet suitable for the cold chain logistics is built.
If no new store or self-lifting cabinet is built, the goods are directly sent to the customer. In the prior art, goods are distributed to a client, and a mode that a plurality of couriers are responsible for a certain area is adopted, for example, an A courier and a B courier are responsible for a first area. The distribution time of the cold chain logistics is directly related to the consumption of cold chain energy consumption, so that the cost of the cold chain logistics is affected, and the lower the storage temperature is, the larger the consumption of cold energy in unit time is, and the higher the cost of the cold chain logistics is. The time requirement of the cold chain logistics is more strict than that of common goods, and the customer usually specifies a time for receiving the goods, so that the difficulty is higher. In order to meet the high requirement, the processing method in the prior art is to input more distribution staff based on the original logistics distribution in one area, for example, input the C courier and the D courier in the first area. However, due to irregular orders, the scheme of the prior art for increasing personnel investment has high labor cost, for example, orders of certain months are large, the four couriers cannot complete the work, and only two couriers are needed for certain month to complete the work.
In addition, in the manner that a plurality of couriers in the prior art are responsible for a certain area, the same number of orders are generally allocated to each courier. Due to the delivery of goods to the gate, the workload of couriers required for different orders is different, so that the manpower is not effectively utilized.
In summary, how to meet the requirement of timing distribution of the cold-chain logistics, and effectively utilize manpower to reduce the manpower cost is a technical problem that needs to be solved by those skilled in the art.

Detailed Description
The core of the invention is to provide a cold chain logistics timing distribution method, which ensures that customers receive goods at regular time and improves the use efficiency of manpower.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for timing delivery of a cold chain logistics, the method includes the following steps:
s101: for each predetermined delivery area, dividing each order of the delivery area into one or more preset time periods according to the required delivery time of each order of the delivery area.
Each delivery area can be predetermined, and can be set and adjusted at any time according to actual conditions. For example, at intervals of 4 to 6 months, the individual delivery areas may be adjusted according to the order distribution.
After each delivery area is determined, each order of the delivery area is divided into one or more preset time periods according to the required delivery time of each order of the delivery area for each preset delivery area.
The demand delivery time refers to the time the customer requires to receive the goods, such as a certain order, and the customer requires to receive the goods at 9 am. The required delivery time is typically selected by the customer at the time of the order. Orders with different required delivery times can be divided into different time periods according to the required delivery time of each order in the delivery area. For example, when implementing the solution of the present invention, the duration of each hour may be generally selected as a time period, for example, the upper half hour and the lower half hour of 2 pm are used as a time period, that is, the time period from 2 pm to 3 pm, and when orders with the time between 2 pm and 3 pm are required to be delivered, the orders may be divided into the time periods. Of course, when the duration of each time period is one hour, the customer-selectable demand delivery time is also typically spanned by one hour at the time of customer placement.
S102: and for each time period, weighting each order according to the address interval between each order and the picking time of each order in the time period, and calculating the weighted order quantity in the time period.
After dividing each order of each delivery area into one or more preset time periods, for each time period, weighting each order according to the address interval between each order and the picking time of each order in the time period, and calculating the weighted order quantity in the time period.
The time of taking the order refers to the time of taking out and distributing the goods in the cold chain logistics vehicle to the customer. The pickup time of different orders is different, for example, the address of a certain order is in a cell, and the cell does not allow the cold chain logistics vehicle to enter, so that the time taken by the courier to take out the goods and send the goods to the customer can be longer. For an order at a location or area, the pickup time of the order at the location or area may be determined from historical data for the location or area and entered into a database. Of course, the data in the database can be adjusted according to the actual situation. The address spacing between orders may also affect the weighting factor, e.g., two or more closely spaced orders, which may be set lower. The weighting coefficient of the corresponding order can be determined according to the address interval and the picking time of each order, and the weighted orders in the time period can be calculated by multiplying each order by the corresponding weighting coefficient and summing.
In one embodiment of the present invention, step S102 may include the following two steps:
the first step: determining a goods taking coefficient corresponding to each goods taking time according to the goods taking time of each order in the time period;
and a second step of: and multiplying each order by a respective goods taking coefficient, multiplying the orders with the address intervals within the interval threshold by a preset interval coefficient according to the address intervals between each order in the time period, and calculating the weighted order quantity in the time period.
Different picking times can correspond to different picking coefficients, for example, after multiplying a certain picking time by a value, the picking coefficient corresponding to the picking time is obtained. And corresponding goods taking coefficients can be distributed for different goods taking time according to different time ranges, for example, the goods taking time is less than or equal to 5 minutes, the corresponding goods taking coefficient is 1, more than 5 minutes and less than or equal to 15 minutes, the goods taking coefficient is set to be 2, and the goods taking coefficient exceeding 15 minutes is set to be 3. Of course, there may be other ways to set the relationship between the pickup time and the pickup coefficient, for example, in implementation, the first step may include:
and for each order in the time period, when the picking time of the order exceeds the standard picking time length, determining that the picking coefficient of the order is greater than 1, otherwise, determining that the picking coefficient of the order is less than 1.
In this embodiment, the standard picking time length may be set and adjusted according to the actual situation, for example, set to 3 minutes, and for each order in the time period, when the picking time of the order exceeds the standard picking time length, it is determined that the picking coefficient of the order is greater than 1, otherwise, it is determined that the picking coefficient of the order is less than 1. For example, the pick-up time of a certain order is 8 minutes, and the pick-up coefficient of the certain order may be determined to be 2, that is, the certain order is equivalent to the original two orders.
And multiplying each order by a respective goods taking coefficient, multiplying the orders with the address intervals within the interval threshold by a preset interval coefficient according to the address intervals between each order in the time period, and calculating the weighted order quantity in the time period. The interval threshold may be set and adjusted according to practical situations, for example, 100 meters may be generally used as the interval threshold. For orders whose address intervals are within the interval threshold, the orders may be multiplied by a preset interval coefficient. For example, there are two orders that are only 10 meters apart, and assuming that the two orders are still 1 after multiplying by the pick factor, when the spacing factor is 0.5, the two orders correspond to the original one. And finally, determining the weighted order quantity of the time period according to the goods taking coefficient and the interval coefficient.
After the weighted amount of orders for the period of the area is determined, the operation of step S103 may be performed.
S103: when the weighted order number of the time period of the delivery area exceeds the distributable order number of the time period, calling and/or additionally dispatching one or more cold chain logistics vehicles from other delivery areas with supporting capability according to the difference value between the weighted order number of the time period of the delivery area and the distributable order number so as to finish cold chain logistics distribution of the time period of the area; wherein, other delivery areas with supporting capability are areas with corresponding weighted orders smaller than the distributable orders in each delivery area except the area.
The number of orders available for distribution over the time period for the area is typically determined by how many distribution personnel are in the area. The more the distribution staff, the higher the amount of orders that can be distributed. For example, the total of 120 orders in the time period of the area is weighted to determine that the weighted order number is 100, the duration of the time period is 1 hour, and it is assumed that each courier can normally distribute 20 orders in 1 hour, and the total of 4 couriers in the time period of the area is provided, the distributable order number in the time period of the area is 80 and is lower than 100.
When the weighted order number of the time period exceeds the distributable order number of the time period, one or more cold chain logistics vehicles are called and/or additionally dispatched from other delivery areas with supporting capability according to the difference value between the weighted order number of the time period and the distributable order number of the delivery area so as to complete the cold chain logistics distribution of the time period of the area. Other delivery areas with support capability are areas in which the corresponding weighted amount of orders is smaller than the amount of deliverable orders in each delivery area other than the area. For example, in the above example, the difference between the weighted amount of orders and the distributable amount of orders in the time period in the delivery area is 20 orders, and a cold chain logistics vehicle may be called from another delivery area having a supporting capability to complete the cold chain logistics distribution in the time period in the area. Of course, when there are no other delivery areas with support capability, or other delivery areas are insufficient to support the delivery of the area, one or more cold chain logistics vehicles may be additionally dispatched to support the delivery of the area for the period of time.
By applying the technical scheme provided by the embodiment of the invention, each order of the delivery area is divided into one or more preset time periods according to the required delivery time of each order of the delivery area for each preset delivery area; for each time period, weighting each order according to the address interval between each order and the picking time of each order in the time period, and calculating the weighted order quantity in the time period; when the weighted order number of the time period of the delivery area exceeds the distributable order number of the time period, calling and/or additionally dispatching one or more cold chain logistics vehicles from other delivery areas with supporting capability according to the difference value between the weighted order number of the time period of the delivery area and the distributable order number so as to finish cold chain logistics distribution of the time period of the area; wherein, other delivery areas with supporting capability are areas with corresponding weighted orders smaller than the distributable orders in each delivery area except the area.
Dividing the order of the delivery area by time period to complete delivery may enable the customer to receive the goods in the corresponding time period. And for each time period, weighting each order according to the address interval between each order and the picking time of each order in the time period, and calculating the weighted order quantity in the time period, so that the actual workload of the couriers needed in the time period can be determined, and the situation that the use efficiency of manpower is reduced due to the fact that the same quantity of orders are distributed to each courier is avoided. When the weighted order number in the time period exceeds the distributable order number, one or more cold chain logistics vehicles are called and/or additionally dispatched from other delivery areas with supporting capability, the distributable order number is determined by the delivery personnel in the area, and because the orders in each area are continuously changed, the manpower and material resources of the area with the distributable order number exceeding the weighted order number are called to the area needing supporting, so that the manpower cost is reduced, and the use efficiency of manpower is improved.
In a specific embodiment of the present invention, before step S101, the method further includes:
and aiming at each preset processing center, according to orders of the delivery areas of the processing centers at the time points of cutting orders, carrying out production and assembly of each order according to the principles of order priority of long delivery distance and order priority of short delivery time in each order.
Since the cold chain logistics distribution scheme of the invention is generally applied to cities, one or more processing centers can be preset for the cities according to the historical distribution of the cities. For example, 3 processing centers are preset according to the historic distribution of Shanghai. For each preset processing center, the production and assembly of each order can be carried out according to the order of the delivery area of the processing center at the time point of the cut-off, and according to the principles of order priority of the delivery distance and order priority of the demand delivery time. Of course, in implementation, the order of production may be adjusted according to other factors, such as priority production of goods that takes longer to order production. If there are multiple machining centers, different delivery areas may be assigned to different machining centers, with each delivery area being at a distance from each machining center. The order can be produced and assembled in the processing center, and in the process, the order can be executed according to the principle that the order with the far delivery distance is prioritized and the order with the near delivery time is prioritized. The delivery distance may be calculated from the time taken to reach the boundary of the delivery area from the machining center. The way in which delivery distance is measured in terms of time rather than in terms of coordinate distance may allow the solution to take into account road smoothness factors. According to the principle that orders with long delivery distance and orders with short delivery time are prioritized in each order, the production and assembly of each order are carried out, so that customers with long distance and short delivery time can receive goods at the delivery time.
In a specific embodiment of the present invention, before each preset machining center performs production and assembly of each order according to the order of the delivery area of the machining center at the time point of cutting, and according to the principle that the order with the far delivery distance and the order with the near delivery time is prioritized in each order, the method may further include:
judging whether the sum of the order quantities of the delivery areas belonging to each processing center exceeds the production threshold of the processing center at a first time point before the cut-off time point for each preset processing center;
if so, then a pre-production is performed at a first point in time.
Because of the specificity of the goods in the cold chain logistics, compared with the common goods, the production and assembly time is longer, and when the order quantity is larger in a certain time period, the situation that the production and assembly are not enough for customers to receive the goods on time may occur. In this embodiment of the invention, for each preset machining center, it may be determined at a first point in time before the cut-off point in time whether the sum of the order amounts of the individual delivery areas belonging to the machining center exceeds the production threshold of the machining center at the first point in time, and if so, the pre-production is performed at the first point in time. The first time point is a time before the time point of the cut-off, and can be set and adjusted according to actual conditions. For example, when the customer wants to receive goods from 2 pm to 5 pm, for example, the customer selects to receive goods from 3 pm when ordering the following items, the customer needs to order the items before 12 pm on the day, and 12 items are the time points of the order. For example, the first time point is 11 a.m., it is determined whether the order quantity exceeds the production threshold of the machining center at 11 a.m., when the production threshold is exceeded, it is indicated that the order quantity is large, and the production of the order can be started at 11 a.m., the pre-production is performed. In the pre-production, the production and assembly of each order may be performed according to the principle that the order with the longer delivery distance and the order with the shorter delivery time are prioritized. By adopting the scheme of pre-production, the cold chain logistics distribution can be performed on time even when the order quantity is large.
It should be noted that, in the foregoing pre-production at the first time point, in other embodiments of the present invention, the order quantity at the time point of the order may be estimated according to the increasing speed of the order before the time point of the order, and when the increasing speed of the order is faster, the pre-production is performed before the time point of the order. In pre-production, products with large or poorly produced production can be prioritized. The number of pre-produced products can be set and adjusted according to the actual situation, for example 60% pre-production.
Moreover, because of the different orders, the time consumed for the production and assembly is different, in one embodiment of the present invention, the pre-production at the first time point may include: pre-production is performed at a first point in time according to the principle of order priority that is time consuming to produce.
In one embodiment of the present invention, the predetermined delivery area may be determined by: one or more delivery areas are assigned to each machining center based on the distribution of the historical orders to equalize estimates of the order quantity for each delivery area. In assigning shipping areas to a machining center, the order volume may be quite different for areas of different area due to geographic location. The order quantity of different areas can be estimated, and when the delivery areas are allocated, the estimated value of the order quantity of each delivery area is equal, so that corresponding manpower and material resources are allocated to each delivery area.
Corresponding to the above method embodiment, the embodiment of the present invention further provides a cold chain logistics timing distribution system, and the cold chain logistics timing distribution system described below and the cold chain logistics timing distribution method described above can be referred to correspondingly.
Referring to fig. 2, a schematic structural diagram of a timing distribution system for cold chain logistics according to the present invention may include the following modules:
an order dividing module 201, configured to divide, for each predetermined delivery area, each order of the delivery area into one or more preset time periods according to a required delivery time of each order of the delivery area;
the order weighting module 202 is configured to weight each order according to an address interval between each order and a picking time of each order in each time period, and calculate a weighted order amount in the time period;
a delivery module 203, configured to call and/or additionally dispatch one or more cold chain logistics vehicles from other delivery areas with supporting capability according to a difference between the weighted order amount and the deliverable order amount of the time period in the delivery area when the weighted order amount of the time period in the delivery area exceeds the deliverable order amount of the time period, so as to complete cold chain logistics delivery of the time period in the area; wherein, other delivery areas with supporting capability are areas with corresponding weighted orders smaller than the distributable orders in each delivery area except the area.
In one embodiment of the present invention, the method further comprises a production assembly module for:
before each order of the delivery area is divided into one or more preset time periods according to the required delivery time of each order of the delivery area for each preset delivery area, production and assembly of each order are carried out according to the principle that the order with the long delivery distance in each order is prioritized and the order with the short required delivery time is prioritized according to the order of the delivery area belonging to the processing center at the cut-off time point for each preset processing center.
