Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic flow chart of a control method of a transportation device according to a first embodiment of the present invention, and as shown in fig. 1, the control method of the transportation device may specifically include the following steps:

step 101: a first container for containing information of a transportation device, a second container for containing information of goods to be dispensed, and a third container for containing clamping information are obtained.

In step 101, the first container is used for containing information of a transportation device, where the transportation device may be a distribution vehicle or a logistics robot, and the information of the transportation device at least includes: the number of the transportation device, the capability parameters, and the corresponding deliverer. Wherein the capability parameter is used for representing the loading capability of a distributor corresponding to the transportation device. The second container is used for containing information of goods to be delivered, and the information of the goods to be delivered at least comprises the following components: cargo number, cargo quantity, delivery destination, etc. The information of the goods to be distributed in the second container takes groups as units, and the number of the goods in each group of the information of the goods is at least one. The third container is used to contain the information of the card positions, which are used to facilitate the structure of the transport device for loading the goods, and are generally arranged at the platform of the distribution center. The screens information includes at least: the card position number and the earliest idle time of the card position. The first container, the second container and the third container may be a set or a list, etc. Wherein the first container, the second container and the third container are preferably a list.

Step 102: and when the goods information of the unloaded goods exists in the second container, taking the goods information of the second container as target goods information.

Before step 102, it may be determined whether cargo information of unloaded cargo exists in the second container; if yes, go to step 102; otherwise, the flow ends.

In step 102, when there are multiple sets of goods information of unloaded goods in the second container, the goods information in the second container may be sorted according to the number of goods in each set of goods information, and each set of goods information is sequentially used as target goods information according to the obtained order, so as to determine a transportation device and a position lock for loading the goods corresponding to the target goods information. For example: the cargo information in the second container can be sorted according to the cargo quantity, and each group of cargo information is used as the target cargo information according to the cargo quantity.

Step 103: and determining a target transportation device according to the target cargo information.

In step 103, a target transportation device may be determined according to a preset correspondence between the transportation device in the first container and the cargo information in the second container and the target cargo information. It is understood that the target transportation device refers to a transportation device for loading the goods corresponding to the target goods information.

In order to make the loading efficiency of the target cargo information higher, the correspondence between the transportation device in the first container and the cargo information of the second container may be predefined before step 103. When defining the corresponding relationship between the transportation devices and the cargo information, each transportation device in the first container may be sorted according to the capability parameter; then sorting each group of goods information in the second container according to the number of the goods; and finally, distributing the cargo information of the second container to the transportation devices of the first container one by one according to the sequence of the transportation devices in the first container and the sequence of the cargo information in the second container, distributing the cargo with the largest quantity of the cargo in the second container to the transportation device with the largest energy parameter in the first container, and forming the corresponding relation between the transportation devices in the first container and the cargo information in the second container.

It should be noted that the capability parameter is used to indicate the loading capability of the corresponding dispenser of the transportation device. To facilitate the description of the capacity parameter, a description of the number of loads per unit time of the dispenser (which may be simply understood as several transporters are loaded) may be used. Since the deliverer of each transporter is fixed, there is a one-to-one correspondence between the transporter and the deliverer, and thus the capability parameter can be identified as an attribute of the transporter. And the higher the capability parameter of the transporter, the stronger the loading capability of the transporter.

Step 104: and according to the preset sequencing of the earliest idle time of each clamping position in the third container, taking the clamping position which is the earliest idle position in the third container as a target clamping position, distributing the target clamping position to the target transportation device, and controlling the target transportation device to dispatch to the target clamping position at the earliest idle time so as to finish the loading process of the goods corresponding to the target goods information.

In step 104, the earliest idle time of the card is used to indicate the time corresponding to the adjustment of the card from the use state to the idle state. The earliest free time for each detent is the time at which the transport device reaches the detent when each detent in the third container is first dispensed. When each card in the third container is again dispensed, the earliest free time of each card can be understood as the time when the transport unit completed loading at the last dispensing, the time when the transport unit completed loading at the last dispensing being the sum of the time when the card was last reached and the time required to load the goods. Because when the first distribution, every screens all is in idle state, and the last distribution promptly the conveyer is the time of accomplishing the loading is 0, the time that the conveyer arrived the screens is the earliest idle time of every screens promptly. To facilitate the allocation of the cards to the transport means, the earliest sequence of idle times for each card in the third container needs to be predefined before step 104.

After step 104, after the target transportation device completes the loading process of the goods corresponding to the target goods information, determining a target delivery path of the target transportation device; and controlling the target transportation device to travel according to the corresponding target delivery route so as to deliver the target goods information loaded by the target transportation device to the corresponding destination correspondingly.

Referring to fig. 4 to 6, in determining the target delivery path of the target transportation device, the origin of the target transportation device and the delivery destination of each group of goods on the target transportation device may be determined first; and then determining a target delivery path of the target transport device by utilizing an operational optimization algorithm according to the origin of the target transport device and the delivery destination of each group of goods on the target transport device. Meanwhile, the receiving time of each delivery node in the target delivery path can be determined; for example: the time of arriving at each distribution node can be estimated according to the travel time between two distribution nodes, the time (service time) of each distribution node needing to stay and the departure time. And then, according to the receiving time of each distribution node in the target distribution path, the receiving time is sent to the receiving terminal corresponding to each distribution node, so that the condition that a distributor confirms the receiving time of the client one by one is avoided.

In addition, after step 104, the earliest free time of the target card may be determined and the ranking of the earliest free time of each card in the third container may be updated according to the earliest free time of the target card. The earliest free time of the target position-blocking can be understood as the sum of the time of the target transportation device reaching the target position-blocking and the time required for loading the corresponding goods of the target goods information.

When the sum of the time required for loading the goods corresponding to the target goods information is determined, firstly, the goods quantity of the target goods information and the capability parameter of the target transportation device are determined; the capacity parameter is used for representing the loading capacity of the transportation device corresponding to the target transportation device; and then determining the time required by the target transportation device to load the goods corresponding to the target goods information according to the goods quantity of the target goods information and the capability parameter of the target transportation device. Since the time required for loading the cargo information by different distributors is different and the distributors and the transportation devices are in one-to-one correspondence, the loading capacity of the distributors can be described by the capacity parameter. The time required by the target transportation device to load the goods corresponding to the target goods information is determined based on the number of the goods to be loaded and the capability parameter of the transportation device, so that the accuracy rate is higher.

In general, the more the number of items to be loaded, the longer the time required for loading, the general trend can be described as: when the number of the goods is less, the time required for loading is steadily increased along with the increase of the number of the goods; however, as the number of the goods increases when the number of the goods is large, the time required for loading increases rapidly. Therefore, it is not suitable to describe the relationship between the cargo quantity of the target cargo information and the required time for loading the cargo corresponding to the target cargo information by using a simple linear relationship, and for this purpose, the following model is proposed to describe the relationship between the cargo quantity of the target cargo information and the required time for loading the cargo corresponding to the target cargo information:

wherein t represents the time required for loading the goods corresponding to the target goods information; x represents the cargo quantity of the target cargo information; x is the number of₀Inflection point, x, representing the amount of cargo loaded₀Is an empirical value; x is the number of_maxRepresents an upper limit of the amount of the loaded goods; a is₁,a₂,a₃,a₄Are all constants.

Under the condition that the quantity of the goods of the target goods information is the same, along with the increase of the capacity parameter, the time required for loading the goods corresponding to the target goods information is steadily reduced and tends to be a stable value, so that the relation between the capacity parameter of the transportation device and the time required for loading the goods corresponding to the target goods information is described by using the following formula:

wherein y represents a parameter of the capacity of the transport device or called the number of loads, a₅,a₆,a₇Are all constants.

In summary, formula 3) can be obtained according to formula 1) and formula 2), and formula 3) is a model that comprehensively considers the cargo quantity of the target cargo information and the capability parameter of the transportation device. The time required for the target transportation device to load the goods corresponding to the target goods information can be determined based on the following formula 3):

it is understood that the ranking of the earliest free time of each card in the third container is formed based on the quantity of goods of the target goods information and the capability parameter of the transporter.

The control method of the transport device in the embodiment of the invention is based on a greedy thought, according to the preset sequencing of the earliest idle time of each clamping position in the third container, the clamping position which is earliest to be idle in the third container is used as a target clamping position, the target clamping position is distributed to the target transport device, and the target transport device is controlled to be dispatched to the target clamping position in the earliest idle time so as to finish the loading process of the goods corresponding to the target goods information. The sorting of the earliest idle time of each card position in the third container is formed based on the quantity of the goods of the target goods information and the capability parameters of the transport device, the method can improve the estimation accuracy of the time required for loading the goods corresponding to the target goods information, has low calculation complexity, and can quickly calculate the scheduling result of the transport device.

Fig. 2 is a schematic flow chart of a control method of a transportation device according to a second embodiment of the present invention, and as shown in fig. 2, the control method of the transportation device may specifically include the following steps:

step 201: a first container for containing information of a transportation device, a second container for containing information of goods to be dispensed, and a third container for containing clamping information are obtained.

In step 201, the first container is used to contain information of a transportation device, which may be a distribution vehicle or a logistics robot, and the information of the transportation device at least includes: the number of the transportation device, the capability parameters, and the corresponding deliverer. Wherein the capability parameter is used for representing the loading capability of a distributor corresponding to the transportation device. The second container is used for containing information of goods to be delivered, and the information of the goods to be delivered at least comprises the following components: cargo number, cargo quantity, delivery destination, etc. The information of the goods to be distributed in the second container takes groups as units, and the number of the goods in each group of the information of the goods is at least one. The third container is used for containing the screens information, the screens function is the structure that the conveyer of being convenient for loaded the goods sets up, the screens generally sets up in platform department. The screens information includes at least: the card position number and the earliest idle time of the card position. The first container, the second container and the third container may be a set or a list, etc. Wherein the first container, the second container and the third container are preferably a list.

Step 202: judging whether goods information of unloaded goods exists in the second container; if yes, go to step 203; otherwise, the flow ends.

Step 203: and when the goods information of the unloaded goods exists in the second container, taking the goods information of the second container as target goods information.

In step 203, when there are multiple sets of goods information of unloaded goods in the second container, the goods information in the second container may be sorted according to the number of goods in each set of goods information, and each set of goods information is sequentially used as target goods information according to the obtained order, so as to determine a transportation device and a position lock for loading the goods corresponding to the target goods information. For example: the cargo information in the second container can be sorted according to the cargo quantity, and each group of cargo information is used as the target cargo information according to the cargo quantity.

Step 204: and determining a target transport device according to the preset corresponding relation between the transport device in the first container and the cargo information in the second container and the target cargo information.

In order to make the loading efficiency of the target cargo information higher, the correspondence between the transportation device in the first container and the cargo information of the second container may be predefined before step 204. When defining the corresponding relationship between the transportation devices and the cargo information, each transportation device in the first container may be sorted according to the capability parameter; then sorting each group of goods information in the second container according to the number of the goods; according to the sequence of the transporting devices in the first container and the sequence of the goods information in the second container, the goods information of the second container is allocated to the transporting devices of the first container one by one, the goods information with the largest quantity of goods in the second container is allocated to the transporting device with the largest energy parameter in the first container, and the corresponding relation between the transporting devices in the first container and the goods information in the second container is formed.

It should be noted that the capability parameter is used to indicate the loading capability of the corresponding dispenser of the transportation device. To facilitate the description of the capacity parameters, a description of the number of loads of the dispenser (which may be simply understood as several transporters are loaded) may be used. Since the deliverer of each transporter is fixed, there is a one-to-one correspondence between the transporter and the deliverer, and thus the capability parameter can be identified as an attribute of the transporter. And the higher the capability parameter of the transporter, the stronger the loading capability of the transporter.

Step 205: and sequentially taking the screens which are earliest vacant in the third container as target screens according to the preset sequencing of the earliest vacant time of each screen in the third container, distributing the target screens to the target transport device, and controlling the target transport device to dispatch the target screens at the earliest vacant time so as to finish the loading process of the goods corresponding to the target goods information.

In step 205, the earliest idle time of the card is used to indicate the time corresponding to the adjustment of the card from the use state to the idle state. The earliest free time for each detent is the time at which the transport device reaches the detent when each detent in the third container is first dispensed. When each card in the third container is again dispensed, the earliest free time of each card can be understood as the time when the transport unit completed loading at the last dispensing. To facilitate the allocation of the cards to the transport device, the earliest sequence of idle times for each card in the third container needs to be predefined before step 205.

After step 205, after the target transportation device completes the loading process of the goods corresponding to the target goods information, determining a target delivery path of the target transportation device; and controlling the target transportation device to travel according to the corresponding target delivery route so as to deliver the target goods information loaded by the target transportation device to the corresponding destination correspondingly.

When determining the target delivery path of the target transportation device, the origin of the target transportation device and the delivery destination of each set of cargo information on the target transportation device may be determined first; and then determining a target delivery path of the target transportation device by using an operation optimization algorithm according to the origin of the target transportation device and the delivery destination of each group of cargo information on the target transportation device, as shown in fig. 4 to 6.

Step 206: and determining the time required by the target transportation device to load the goods corresponding to the target goods information.

In step 206, determining the cargo quantity of the target cargo information and the capability parameter of the target transportation device; wherein the capability parameter is used to represent a loading capability of the target transporter; and determining the time required by the target transportation device to load the goods corresponding to the target goods information according to the goods quantity of the target goods information and the capability parameter of the target transportation device. Since the time required for loading the cargo information by different distributors is different and the distributors and the transportation devices are in one-to-one correspondence, the loading capacity of the distributors can be described by the capacity parameter. The time required by the target transportation device to load the goods corresponding to the target goods information is determined based on the number of the goods to be loaded and the capability parameter of the transportation device, so that the accuracy rate is higher.

In summary, formula 3) can be obtained according to formula 1) and formula 2), and formula 3) is a model that comprehensively considers the cargo quantity of the target cargo information and the capability parameter of the transportation device. It will be appreciated that the model takes into account two influencing factors: the loading task amount and the operation proficiency of the distributor; the loading task quantity is converted into the quantity of goods to be loaded for description, and the operation proficiency of a distributor is converted into capability parameter description, namely the historical loading times of a loading worker. The model can improve the estimation accuracy of the time required by loading the cargo information.

Further, the time required for the target transportation device to load the goods corresponding to the target goods information may be determined based on the following formula 3):

step 207: and determining the next earliest idle time of the target clamping position according to the sum of the time required by the target transportation device to load the corresponding goods of the target goods information.

In step 207, the next earliest idle time of the target card may be understood as the time when the target transportation device completes the loading task of the goods corresponding to the target goods information or the earliest idle time corresponding to the next allocation of the target card. It can be understood that the next earliest idle time of the target position lock may be the sum of the time when the target transportation device reaches the target position lock and the time required for loading the corresponding goods of the target goods information.

Step 208: and updating the sequencing of the earliest idle time of each card position in the third container and the grouping number of the goods information of the unloaded goods in the second container according to the next earliest idle time of the target card position. After step 208, step 202 continues until all of the contents of the second container are loaded.

The second container is used for containing information of goods to be delivered, and the information of the goods to be delivered at least comprises the following components: cargo number, cargo quantity, delivery destination, etc. The information of the goods to be distributed in the second container takes groups as units, and the number of the goods in each group of the information of the goods is at least one.

After step 309, the method further comprises: after the target transportation device finishes the loading process of the goods corresponding to the target goods information, determining a target distribution path of the target transportation device; and controlling the target transportation device to travel according to the corresponding target delivery route so as to deliver the target goods information loaded by the target transportation device to the corresponding destination correspondingly.

When determining the target delivery path of the target transportation device, the origin of the target transportation device and the delivery destination of each set of cargo information on the target transportation device may be determined first; and then determining a target distribution path of the target transport device by using an operational optimization algorithm according to the origin of the target transport device and the distribution destination of each group of cargo information on the target transport device.

Step 310: and determining the quantity of the goods corresponding to the target goods information and the capacity parameter corresponding to the target transportation device.

In step 310, the capability parameter may be understood as the number of loads of the dispenser.

Step 311: and determining the time required by the target transportation device to load the goods corresponding to the target goods information according to the quantity of the goods corresponding to the target goods information and the capacity parameter corresponding to the target transportation device.

The time required by the target transportation device to load the goods corresponding to the target goods information is determined based on the number of the goods to be loaded and the capability parameter of the transportation device, so that the accuracy rate is higher.

step 312: and determining the next earliest idle time of the target clamping position according to the sum of the time required by the target transportation device to load the corresponding goods of the target goods information.

In step 312, the next earliest idle time of the target card may be understood as the time when the target transportation device completes the loading task of the goods corresponding to the target goods information or the earliest idle time corresponding to the target card when the target card is allocated next time. It can be understood that the next earliest idle time of the target position lock may be the sum of the time when the target transportation device reaches the target position lock and the time required for loading the corresponding goods of the target goods information.

Step 313: and updating the sequencing of the earliest idle time of each card position in the third container and the grouping number of the goods information of the unloaded goods in the second container according to the next earliest idle time of the target card position. Step 306 continues after step 313.

For convenience of describing the control method of the transportation apparatus, the following variables are defined: assuming that the second container has n groups of information of the goods to be distributed, which is expressed as g₁,g₂,…,g_nThe number of the corresponding groups is

The number of vehicles available for transporting the corresponding cargo information is n, denoted as { v }₁,v₂,…,v_n}. The third container has a bit number of m, which is expressed as p₁,p₂,…,p_m}。

To facilitate the description of the control method of the transport apparatus, several assumptions are made as follows:

(i) the distributors correspond to the transportation devices one by one and can be used at any time;

(ii) the cargo information of the transporter is determined, i.e. the amount of loading tasks is constant during the scheduling of the transporter;

(iii) after the transport device on the screens finishes the loading task, the screens are immediately in an idle state, and the time for the transport device to leave and enter the screens is ignored;

(iv) the property of screens is the same, and cargo information of any group can be loaded in any screens.

Based on the greedy thought and the above assumptions, the specific processing procedure of the control method of the transportation device is as follows:

(1) arranging the cargo information of the cargo to be loaded in the second container from large to small according to the cargo quantity, and assuming that the result of the sequencing of the cargo information of the cargo to be loaded in the second container is { g }₁,g₂,…,g_n}；

(2) Sorting the transportation devices of the first container according to capacity parameters, wherein the transportation devices with large capacity parameters are arranged in front, and assuming that the sorting result of the transportation devices of the first container is { v }₁,v₂,…,v_n}；

(3) In order to improve the loading efficiency, the transportation device with large capacity parameter can be allocated to the cargo information with large quantity of cargos, namely, the following corresponding relation exists

{v₁→g₁,v₂→g₂,…,v_n→g_nAt this time, the number of the transportation devices to be dispatched is n, and the number of the cargo information groups to be loaded is n;

(4) after the transportation device of the first container is matched with the cargo information of the second container, each group of cargo information in the second container can be used as target cargo information, a target transportation device corresponding to the target cargo information is determined, and then the sum of time required for each target transportation device to load the cargo corresponding to the target cargo information is determined, and it is assumed that the time required for loading each cargo information in the second container is represented as

{v₁→g₁→t₁,v₂→g₂→t₂,…,v_n→g_n→t_n}；

(5) At the initial allocation stage of the card blocking, if the number m of idle card positions in the third container is greater than or equal to the number n of cargo information groups of the transportation device in the first container, the transportation device in the first container can arrive at the logistics service center at the time t to execute a loading task without extra waiting time, and the corresponding time of the cargo information loaded by the transportation device corresponding to the group number and the completion of loading is as follows:

{v₁→g₁→t+t₁,v₂→g₂→t+t₂,…,v_n→g_n→t+t_n}. If the free clamping number m in the third container is less than the cargo information grouping number n of the transport device in the first container, namely m<n, then the first m transporters in the first set are selected to arrive at the distribution center at time t for carrying out the loading task ({ v)₁→t,v₂→t,…,v_m→ t }). At this time, the corresponding group numbers of the cargo information loaded by the m transport devices and the corresponding time for completing the loading are as follows:

{v₁→g₁→t+t₁,v₂→g₂→t+t₂,…,v_m→g_m→t+t_mthe loading completion time is the earliest idle time of the corresponding screens, namely the earliest idle time of the screens is

{p₁→t+t₁,p₂→t+t₂,…,p_m→t+t_m}. And the remaining n-m groups of cargo information in the second container are represented by a variable k, wherein k is n-m. The number of the to-be-scheduled transport devices is n-m, and the matching relation between the to-be-scheduled transport devices and the residual n-m groups of cargo information in the second container is { v [ ]_m→g_m,…,v_n→g_n},m＜n。

(6) In the redistribution stage of the screens, if the grouping number k of the residual goods information in the second container is greater than 0, sorting the screens according to the earliest idle time, and assuming that the sorting result is

The first detent assigned to the earliest possible space is removed in accordance with the group sequence of the cargo information in the second container, i.e. the first detent

And updates the earliest free time of the card

Simultaneously updating cargo information of unloaded cargo in the second containerK is k-1. If the group number k of the cargo information in the second container is equal to 0, the cargo information in the second container is completely distributed, and the dispatching of the transport device in the first container is completed; if the number of groups of the cargo information in the second container is k>0, continuing to execute the step of card position redistribution.

Next, the processing procedure of the control method of the transport apparatus of the present application will be described exemplarily with reference to the drawings and tables. It should be noted that one order to be delivered corresponds to one group of information on the goods to be delivered.

The existing warehouse has a station number of 10 (numbers v1, v2, …, v10), i.e. the station number of the third container is 10, the covered area is divided into 20 distribution units (numbers s1, s2, …, s20), each distribution unit is equipped with a transport device (numbers p1, p2, …, p20), i.e. the number of transport devices of the first container is 10. Assume that the total number of units to be delivered on the day is 1200 units, i.e., the number of goods in the second container is 1200. The average capacity of the warehouse was 10 units/minute, and the warehouse was operated at 6: 00. If the production is not performed according to the distribution unit, the worst case is that: 7:58 there will be a first delivery unit to complete the production of all orders; if production is to be performed by the delivery units, the time at which the delivery units complete production is predicted as shown in Table 1, and it can be seen that the earliest 6:08 delivery unit has the first delivery unit to complete production of all orders.

TABLE 1 estimated production completion time for each delivery unit

For convenience of calculation, assuming that the transportation device is notified to the warehouse at intervals of 10min for picking up goods, the transportation device may be allocated to each delivery unit according to step 103 or step 204, and the time for completing loading may be estimated using the above formula 3), and this time is taken as the time for completing picking up goods, as shown in table 2, it can be seen that there is no vehicle waiting after arriving at the warehouse.

As can be seen from table 2, the dispenser does not need to wait while picking. If the dispenser is scheduled to arrive at a uniform time (e.g., 8:00), it will wait at least 1 hour for picking. However, in the actual distribution process, the distributors often distribute according to personal experiences and habits, and do not globally consider the overall distribution order, which may cause problems such as long driving route and long overall distribution time in the distribution process, and affect the distribution efficiency. In order to solve the unreasonable problem of manual sequencing, an operation and raising optimization algorithm can be adopted to carry out path planning from the global perspective. To more clearly illustrate the advantage of road engineering using the operational research optimization method, the following description is made with reference to test data, as shown in table 3. In order to more intuitively understand the distribution of the orders to be delivered, the data of table 3 is shown on a two-dimensional plane, as shown in fig. 4.

As shown in fig. 5, the delivery person performs actual delivery routes corresponding to the delivery according to his/her own delivery experience and habit. Fig. 6 shows the distribution path obtained by the operation and research optimization algorithm, and as can be seen from fig. 6, the distribution path planned by the operation and research optimization method can avoid walking around. After the distribution path is planned, the receiving time of each distribution node in the target distribution path can be determined; for example: the time of arriving at each distribution node can be estimated according to the travel time between two distribution nodes, the time (service time) of each distribution node needing to stay and the departure time. And then, according to the receiving time of each distribution node in the target distribution path, the receiving time is sent to the receiving terminal corresponding to each distribution node, so that the condition that a distributor confirms the receiving time of the client one by one is avoided.

In summary, the method is considered from the global perspective, the warehouse production flow, the delivery time of the deliverer, the distribution path planning, the estimated arrival time of the client point and the like are reasonably arranged, the distribution efficiency of the deliverer can be improved to a certain extent, and the overall working time of the deliverer is shortened.
