Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction machinery and equipment in and out of storage, and in particular to an electric power construction machinery and equipment in and out of storage management method based on intelligent warehousing. Background Art

[0002] The management of the in and out of the warehouse of electric power construction machinery is the core link of the supply chain management of the power industry. Especially in the context of the growing demand for power equipment and materials, efficient inventory management technology is particularly important. For online delivery, the management system of electric power construction machinery needs to ensure that each material is accurately picked and sent out from the warehouse in a timely manner to ensure the smooth progress of the power project and the timeliness of maintenance work. In terms of the recovery and re-warehousing of returned construction machinery, the challenges faced by the management of electric power construction machinery include how to quickly and accurately reclassify, inspect and store the returned materials. This is not only related to the accuracy of inventory, but also affects the reuse rate and cost control of materials. The returned construction machinery materials need to undergo strict quality inspections to ensure that they meet the standards for reuse. In addition, for damaged or outdated materials, there needs to be an effective processing process to avoid inventory backlogs and waste of resources. Efficient logistics distribution and precise inventory control are the key to ensuring the stable operation of the supply chain in the power industry.

[0003] In the prior art, when it is determined that the returned power construction equipment is intact based on the reason for returning the construction equipment, if a new construction team happens to make an appointment to use power construction equipment of the same type as the returned power construction equipment, then the warehouse needs to first recycle the power construction equipment to the warehouse, and then send the power construction equipment to the new construction team. Since the power construction equipment is not damaged, the material warehouse only repackages the returned power construction equipment and sends it to the new construction team. For the power construction equipment, this process is just a matter of repackaging and reshipping. The first holder is the construction team that returns the construction equipment, and the last holder is the new construction team. This eliminates the need for warehouse middlemen, reducing the efficiency of warehouse distribution.

[0004] This scheme proposes that when the construction team is judged to be the second construction team through the reason for withdrawing the construction equipment, the time of withdrawing the construction equipment of the second construction team is predicted, and the delivery time judgment strategy, delivery type judgment strategy and delivery distance screening strategy are respectively implemented to calculate the optimal delivery method for the first construction team.

[0085] The present invention has the following beneficial effects:

[0086] 1. The method for managing the entry and exit of electric construction machinery based on intelligent warehousing sets two types of reasons for returning construction machinery, obtains the reasons for returning construction machinery of the construction team, obtains the keywords in the reasons for returning construction machinery of the construction team from the material warehouse, obtains the second keyword group, and compares it with the first keyword group set by the material warehouse, obtains the number of identical elements in the two keyword groups, and obtains the number of damaged words. As long as the number of damaged words is greater than 0, it means that the electric construction machinery returned by the construction team is damaged. At this time, the electric construction machinery returned must be recycled into the warehouse. When the number of damaged words = 0, it means that the electric construction machinery returned is intact, and the electric construction machinery returned can be sent to a new construction team under certain conditions. By judging whether the electric construction machinery returned is intact according to the reasons for returning construction machinery, the first screening is performed according to the reasons for returning construction machinery, so as to facilitate the subsequent judgment of whether the electric construction machinery returned will be sent to a new construction team, thereby improving the efficiency of warehouse distribution, reducing the number of electric construction machinery entering and leaving the warehouse, and improving the efficiency of warehouse operation.

[0087] 2. The method for managing the entry and exit of electric construction machinery based on intelligent warehousing divides the methods for returning construction machinery of the second construction team into return by designated transport units and self-mailing. When the method for returning construction machinery of the second construction team is return by designated transport units, the midpoint time of the time period for return by designated transport units set by the second construction team is obtained to obtain the time for returning the construction machinery; when the method for returning construction machinery of the second construction team is self-mailing, since the application time and the actual time for returning the electric construction machinery vary due to the different habits of each construction team, and are also related to whether the time for applying for the return of the construction machinery is on a weekday or a weekend, the application time categories are divided into two categories, namely, the first application time is on a weekday, and the second application time is on a weekend. For any one of the first application time and the second application time Specifically, the processed application time is recorded as the marked application time; all waiting periods for construction machinery return of the marked application time in the historical records of construction machinery return are obtained, the mean is calculated, and the average waiting period for construction machinery return of the marked application time is obtained, and then the average waiting period for construction machinery return of the first category of application time and the average waiting period for construction machinery return of the second category of application time are obtained, and the average waiting period for construction machinery return of the category of application time in which the second construction team currently applies is obtained to obtain the time of construction machinery return, and the application time for construction machinery return is divided into two categories, and the average waiting period for construction machinery return is calculated in each category. The waiting period for construction machinery return is calculated more accurately, and the time of construction machinery return is predicted, so as to facilitate the subsequent second screening of the construction teams returning the construction machinery through time, thereby improving the efficiency of warehouse distribution.

[0088] 3. The method for managing the entry and exit of electric power construction machinery based on intelligent warehousing obtains the appointment time for collection by the first construction team, obtains the time when the material warehouse agrees to send out the electric power construction machinery to obtain the shipping time, and the time period between the appointment time for collection and the shipping time is recorded as the shipping waiting period. The time for returning the construction machinery obtained by executing the prediction strategy for the time for returning the construction machinery is obtained, and the second construction team corresponding to the time for returning the construction machinery in the shipping waiting period is obtained. The second construction team is recorded as the third construction team, and the second construction team is screened for the second time by time to obtain the second construction team whose time meets the conditions for sending the returned electric power construction machinery to the first construction team, thereby improving the efficiency of warehouse distribution, reducing the number of electric power construction machinery entering and leaving the warehouse, and improving the efficiency of warehouse operation.

[0089] 4. The method for managing the entry and exit of electric construction machinery based on intelligent warehousing obtains the types of materials for which the first construction team has made an appointment to use the electric construction machinery, screens all third construction teams whose types of electric construction machinery returned are equal to the types of materials, and records them as marked construction teams. The construction teams that return the construction machinery are screened for the third time by the types of materials to obtain marked construction teams, obtain the number of construction machinery returned by each marked construction team, obtain the number of construction machinery returned, obtain the number of materials for which the first construction team has made an appointment to use the electric construction machinery, and divide the number of construction machinery returned into multiple combinations based on the standard of being equal to the number of materials. The combination contains one or more elements in the number of construction machinery returned. When there is only one element in the combination, this element is equal to the number of materials. When the combination contains more than 2 elements, it means that each element in the combination is less than the quantity of materials, and the sum of all elements in the combination is equal to the quantity of materials; when there is a combination, it means that the quantity in the combination can just meet the demand of the first construction team for appointment to use the electric construction machinery. When there is no combination, the warehouse must send the electric construction machinery to the first construction team, and conduct a fourth screening of the construction teams returning the construction machinery according to the quantity of materials to obtain the fourth construction team. The fourth construction team can send the electric construction machinery that has returned the construction machinery to the first construction team, and send the electric construction machinery that has returned the construction machinery directly to the first construction team, so as to improve the efficiency of warehouse distribution, reduce the number of electric construction machinery entering and leaving the warehouse, and improve the efficiency of warehouse operation.

[0090] 5. The method for managing the entry and exit of electric power construction machinery based on intelligent warehousing, for any combination, obtains any fourth construction team in the combination, obtains the first waiting time according to the time of returning the construction machinery and the appointment time of the fourth construction team, obtains the distance from the fourth construction team to the first construction team, obtains the delivery distance, calculates the delivery distance*unit time, obtains the first delivery time, calculates the sum of the first delivery time and the first waiting time, obtains the second waiting time, obtains the second waiting time of each fourth construction team in the combination, calculates the mean, obtains the average waiting time of each combination, obtains the combination with the smallest average waiting time, obtains the target construction machinery return group, then, the target construction machinery return group is the group with the fastest delivery time, by calculating the target construction machinery return group with the fastest delivery time, the electric power construction machinery returned in the target construction machinery return group is sent to the first construction team, speeds up the time from appointment to receipt of the first construction team, and improves the service satisfaction of the first construction team.

[0091] 6. The method for managing the entry and exit of electric power construction machinery based on intelligent warehousing sets a threshold time to quantify the additional costs required for shipping from the warehouse, such as labor costs, packaging material costs, etc., obtains the warehouse distance, calculates the warehouse distance * unit time + interval time + threshold time, obtains the third waiting time, and compares the third waiting time with the average waiting time. When the average waiting time > the third waiting time, the warehouse will ship the goods to the first construction team, and the fourth construction team will return the electric power construction machinery to the warehouse. When the average waiting time ≦ the third waiting time, the electric power construction machinery of the fourth construction team in the target returned construction machinery group will be returned to the warehouse. The equipment is sent to the first construction team. This method is suitable for when the time of shipment from the warehouse is much shorter than the time of sending the electric construction equipment returned by the fourth construction team to the first construction team. In this case, the equipment is shipped from the warehouse to the first construction team. The threshold time is a variable value set by the material warehouse. For example, when the threshold time is longer, it means that the material warehouse is more inclined to send the construction equipment returned by the fourth construction team to the first construction team. When the threshold time is shorter, it means that the construction team is more inclined to ship from the warehouse to the first construction team. A warehousing and access method that can be adjusted by the material warehouse is provided to facilitate the material warehouse to better manage the warehousing and access of electric construction equipment and improve the efficiency of warehousing and access.

[0102] The construction team whose reason for returning construction equipment belongs to the second category will be recorded as the second construction team;

[0103] For each second construction team:

[0150] Obtain elements whose quantity is equal to the quantity of materials in the set of the quantity of construction equipment to be withdrawn, and form each element whose quantity is equal to the quantity of materials into a combination;

[0151] In the set of the number of withdrawn construction tools, elements whose number is less than the number of materials are obtained. Among all the elements whose number is less than the number of materials, two or more elements are selected so that the sum of the selected elements is equal to the number of materials. The elements whose sum is equal to the number of materials are combined into a combination.

[0152] If the combination exists, the match is successful;

[0153] If no combination exists, the warehouse will send the electric construction machinery to the first construction team.

[0154] Get the types of materials that the first construction team has reserved for electric construction machinery and tools, filter out all third construction teams whose types of electric construction machinery and tools are equal to the types of materials, record them as marked construction teams, perform a third screening on the construction teams that have returned construction machinery and tools by material types, get marked construction teams, get the number of construction machinery and tools returned by each marked construction team, get the number set of returned construction machinery and tools, get the number of materials that the first construction team has reserved for electric construction machinery and tools, divide the number set of returned construction machinery and tools into multiple combinations based on the standard of being equal to the number of materials, and the combination contains one or more elements in the number set of returned construction machinery and tools. When there is only one element in the combination, this element is equal to the number of materials. When the combination contains two or more elements, this element is equal to the number of materials. When there is an element, it means that each element in the combination is less than the quantity of materials, and the sum of all elements in the combination is equal to the quantity of materials; when there is a combination, it means that the quantity in the combination can just meet the demand of the first construction team for appointment to use the electric construction machinery. When there is no combination, the warehouse must send the electric construction machinery to the first construction team, and conduct a fourth screening of the construction teams that return the construction machinery according to the quantity of materials to obtain the fourth construction team. The fourth construction team can send the electric construction machinery that returns the construction machinery to the first construction team, and send the electric construction machinery that returns the construction machinery directly to the first construction team, so as to improve the efficiency of warehouse distribution, reduce the number of electric construction machinery entering and leaving the warehouse, and improve the efficiency of warehouse operation.

[0155] The execution of the delivery distance screening strategy includes:

[0156] For any combination;

[0157] Get any fourth construction team in the combination;

[0158] Obtain the time when the fourth construction team's construction equipment is withdrawn;

[0159] Get the appointment time of the first construction team;

[0160] The length of the period formed by the appointment time for receiving the construction equipment and the time for returning the construction equipment is recorded as the first waiting time;

[0161] Get the time spent on a unit journey in the historical delivery records and record it as unit time;

[0162] Get the distance between the fourth construction team and the first construction team, and record it as the delivery distance;

[0163] Calculate the delivery distance * unit time, and record the result as the first delivery time;

[0164] Calculate the first waiting time + the first delivery time, and record the result as the second waiting time;

[0165] Obtain the second waiting time of each fourth construction team, calculate the average, and record the result as the average waiting time of the combination;

[0166] Get the average waiting time of all combinations, get the combination with the minimum average waiting time, and record it as the target construction equipment group.

[0167] For any combination, obtain any fourth construction team in the combination, obtain the first waiting time according to the time of returning the construction equipment and the appointment time of the fourth construction team, obtain the distance from the fourth construction team to the first construction team, obtain the delivery distance, calculate the delivery distance * unit time, obtain the first delivery time, calculate the sum of the first delivery time and the first waiting time, obtain the second waiting time, obtain the second waiting time of each fourth construction team in the combination, calculate the mean, obtain the average waiting time of each combination, obtain the combination with the smallest average waiting time, and obtain the target construction equipment return group. Then, the target construction equipment return group is the group with the fastest delivery time. By calculating the target construction equipment return group with the fastest delivery time, the power construction equipment returned in the target construction equipment return group is sent to the first construction team, which speeds up the time from purchase to receipt of the first construction team and improves the service satisfaction of the first construction team.

[0168] The execution of the delivery distance screening strategy includes:

[0169] Get the distance from the warehouse to the first construction team, recorded as warehouse distance;

[0170] Get the duration of the delivery waiting interval;

[0171] Set the threshold time for determining whether to ship from the warehouse;

[0172] Calculate warehouse distance * unit duration + interval duration + threshold duration, and record the result as the third waiting time;

[0173] Obtain the average waiting time of the target construction equipment group;

[0174] Compare the average wait time to the third wait time:

[0175] When the average waiting time > the third waiting time;

[0176] Then the address of the warehouse is obtained, and the address of the warehouse is sent to each fourth construction team in the target construction equipment return group as the construction equipment return address of the fourth construction team;

[0177] The warehouse sends electrical construction machinery and tools to the first construction team;

[0178] When the average waiting time ≦ the third waiting time, the harvest address of the first construction team is obtained, and the harvest address of the first construction team is sent to each fourth construction team in the target construction equipment withdrawal group as the construction equipment withdrawal address of the fourth construction team.

[0179] By setting a threshold time, it is used to quantify the additional costs required for shipping from the warehouse, such as labor costs, packaging material costs, etc., to obtain the warehouse distance, calculate warehouse distance * unit time + interval time + threshold time, and get the third waiting time. The third waiting time is compared with the average waiting time. When the average waiting time > the third waiting time, the warehouse will ship the goods to the first construction team, and the fourth construction team will return the electric construction machinery to the warehouse. When the average waiting time ≦ the third waiting time, the electric construction machinery returned by the fourth construction team in the target construction machinery return group will be sent to the first construction team. This method is applicable when the time for shipping from the warehouse is much shorter than the time for sending the electric construction machinery returned by the fourth construction team to the first construction team. In this case, the goods are shipped from the warehouse to the first construction team, wherein the threshold time is a variable value set by the material warehouse. For example, when the threshold time is longer, it means that the material warehouse is more inclined to send the construction machinery returned by the fourth construction team to the first construction team. When the threshold time is shorter, it means that the construction team is more inclined to ship from the warehouse to the first construction team. This provides an in-and-out storage method that can be adjusted by the material warehouse, so as to better manage the in-and-out storage of electric construction machinery and improve the efficiency of in-and-out storage.
