Description

Technical Field

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

[0002] The inbound and outbound management of power construction equipment is a core component of supply chain management in the power industry. Efficient inventory management techniques are particularly crucial, especially given the growing demand for power equipment and materials. For online shipments, the power construction equipment management system must ensure that each item is accurately picked and dispatched from the warehouse on time, ensuring the smooth progress of power projects and timely maintenance work. When it comes to the recycling and restocking of returned equipment, challenges in power construction equipment management include quickly and accurately reclassifying, inspecting, and storing returned equipment. This not only impacts inventory accuracy but also material reuse rates and cost control. Returned equipment and materials undergo rigorous quality inspections to ensure they meet reusable standards. Furthermore, an effective process is required for handling damaged or obsolete materials to avoid inventory backlogs and resource waste. Efficient logistics and precise inventory control are key to ensuring the stable operation of the power industry's supply chain.

[0003] In the existing technology, when the returned power construction equipment is judged to be intact based on the reason for returning the construction equipment, if a new construction team happens to make an appointment to collect 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 changing the packaging and reshipping. The first holder is the construction team that returned the construction equipment, and the final holder is the new construction team. The warehouse middlemen are redundant, which reduces the efficiency of warehouse distribution.

[0004] This solution proposes that when the construction team is judged to be the second construction team based on the reason for returning the construction equipment, the time when the second construction team returns the construction equipment 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 equipment based on intelligent warehousing sets two types of reasons for returning construction equipment, obtains the reasons for returning construction equipment by the construction team, obtains the keywords in the reasons for returning construction equipment by 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 to obtain 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 equipment returned by the construction team is damaged. At this time, the electric construction equipment must be recycled and put into the warehouse. When the number of damaged words = 0, it means that the electric construction equipment returned is intact and can be sent to a new construction team under certain conditions. By judging whether the electric construction equipment returned is intact based on the reasons for returning construction equipment, the first screening is performed based on the reasons for returning construction equipment, which facilitates the subsequent judgment of whether to send the returned electric construction equipment to a new construction team, thereby improving the efficiency of warehouse distribution, reducing the number of electric construction equipment 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 by the second construction team into return by designated transport units and self-mailing. When the method for returning construction machinery by the second construction team is return by designated transport units, the midpoint of the time interval 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 by the second construction team is self-mailing, since the application time and the actual time for returning the electric construction machinery vary according to the 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 on 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 of the first and second application times, Specifically, the processed application time is recorded as the marked application time; all the waiting periods for returning construction machinery with marked application times in the historical records of returning construction machinery are obtained, and the mean is calculated to obtain the average waiting period for returning construction machinery with marked application times, and then the average waiting period for returning construction machinery with the first category of application times and the average waiting period for returning construction machinery with the second category of application times are obtained, and the average waiting period for returning construction machinery of the category of application time at the current application moment of the second construction team is obtained to obtain the time for returning construction machinery, and the time for returning construction machinery is obtained by dividing the application time for returning construction machinery into two categories and calculating the average waiting period for returning construction machinery in each category. The waiting period for returning construction machinery is calculated more accurately and the time for returning construction machinery is predicted, so as to facilitate the subsequent second screening of the construction teams returning construction machinery by time, thereby improving the efficiency of warehouse distribution.

[0088] 3. The method for managing the entry and exit of electric construction equipment 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 construction equipment to obtain the shipping time, and the time period between the appointment time and the shipping time is recorded as the shipping waiting interval. The time for returning the construction equipment obtained by executing the construction equipment return time prediction strategy is obtained, and the second construction team corresponding to the time for returning the construction equipment in the shipping waiting interval 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 construction equipment to the first construction team, thereby improving the efficiency of warehouse distribution, reducing the number of electric construction equipment 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 receive electric construction machinery, screens all third construction teams whose types of returned electric construction machinery are equal to the types of materials, and records them as marked construction teams. The construction teams that have returned 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 set of returned construction machinery, obtain the number of materials for which the first construction team has made an appointment to receive electric construction machinery, and divide the number set of returned construction machinery 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 set of returned construction machinery. 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 material quantity, and the sum of all elements in the combination is equal to the material quantity; when there is a combination, it means that the quantity in the combination can just meet the demand of the first construction team to make an appointment to collect 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 based on the material quantity to obtain the fourth construction team. The fourth construction team can then send the returned electric construction machinery to the first construction team, and send the returned electric construction machinery directly to the first 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.

[0090] 5. The method for managing the entry and exit of electric power construction equipment based on intelligent warehousing, for any combination, obtains any fourth construction team in the combination, obtains the first waiting time according to the time when the fourth construction team returns the construction equipment and the time when the reservation is made, 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 average, obtains the average waiting time of each combination, obtains the combination with the smallest average waiting time, obtains 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 electric power construction equipment returned in the target construction equipment return group is sent to the first construction team, speeds up the time from the reservation to the 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 shipment 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, compares the third waiting time with the average waiting time, and 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 returned by 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 applicable when the time for shipment from the warehouse is much less than the time for 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. Providing an in-and-out warehousing method that can be adjusted by the material warehouse is convenient for the material warehouse to better manage the in-and-out of electric construction equipment and improve the efficiency of in-and-out warehousing.

[0093] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0094] Example 1, refer to Figure 1 , a method for managing the entry and exit of electric power construction tools based on intelligent warehousing, comprising:

[0095] Obtaining the location information of the warehouse used to store electric construction equipment;

[0096] The electric power construction machinery and tools are inventory materials stored in the material warehouse;

[0097] Record the order information of each construction team through the warehouse order module;

[0098] Record the construction team information applying for after-sales processing through the warehouse return and exchange module;

[0099] The warehouse entry and exit management module is used to manage the power construction machinery and tools entering and leaving the warehouse based on the data from the warehouse order module and the warehouse return and exchange module;

[0100] Obtain the reasons for the construction team applying for the withdrawal of construction equipment, execute the strategy for determining the reasons for the withdrawal of construction equipment, and determine the type of reasons for the withdrawal of construction equipment, where the reasons are divided into first and second types.

[0101] Among them, the return of construction equipment refers to the construction team returning the purchased power construction equipment to the material warehouse;

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

[0103] For each second construction team:

[0104] Obtain the method for returning the construction equipment of the second construction team, execute the prediction strategy for the time of returning the construction equipment, obtain the time when the second construction team's returned power construction equipment begins to be transported, and record it as the time of returning the construction equipment;

[0105] The construction team that has made an appointment to receive electric power construction machinery and equipment but has not yet received the reserved electric power construction machinery and equipment will be recorded as the first construction team;

[0106] Execute the delivery time judgment strategy to determine whether the time condition for sending the electric power construction equipment returned by the second construction team to the first construction team is met;

[0107] If the time condition is met, the second construction team that meets the time condition will be recorded as the third construction team;

[0108] Execute the distribution type judgment strategy to determine whether the types of electric power construction equipment returned by the third construction team are equal to the types of electric power construction equipment reserved for the first construction team, and match the corresponding third construction team based on the number of electric power construction equipment reserved for the first construction team;

[0109] The third construction team that is successfully matched is recorded as the fourth construction team;

[0110] Implement the delivery distance screening strategy to select the fastest delivery method from the warehouse and the fourth construction team;

[0111] If the time conditions are not met, the warehouse will send the electrical construction equipment to the first construction team.

[0112] The strategy for determining the reason for returning the construction equipment includes:

[0113] The first type of reason is the return of construction equipment due to damage to the electric construction equipment;

[0114] The second type of reasons are reasons for returning construction equipment excluding damage to electric construction equipment;

[0115] Obtain keywords related to damage of electric power construction equipment set in the material warehouse to form the first keyword group;

[0116] Obtain the reasons for the construction team's return of construction equipment;

[0117] Obtain keywords related to the reasons for the withdrawal of construction equipment to form a second keyword group;

[0118] Obtain the number of identical elements in the first keyword group and the second keyword group, and record it as the number of broken words;

[0119] When the number of broken words is greater than 0, the reason for the construction team to return the construction equipment is the first type of reason;

[0120] When the number of damaged words = 0, the reason why the construction team returned the construction equipment is the second type of reason.

[0121] By setting two types of reasons for returning construction machinery, the reasons for returning construction machinery by the construction team are obtained. The materials warehouse obtains the keywords in the reasons for returning construction machinery by the construction team to obtain a second keyword group, which is compared with the first keyword group set by the materials warehouse to obtain the number of identical elements in the two keyword groups and 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 can be sent to a new construction team under certain conditions. By judging whether the electric construction machinery returned is intact based on the reasons for returning construction machinery, the first screening is performed based on the reasons for returning construction machinery, which facilitates the subsequent judgment of whether to send the returned electric construction machinery to a new construction team. This improves the efficiency of warehouse distribution, reduces the number of electric construction machinery entering and leaving the warehouse, and improves the efficiency of warehouse operation.

[0122] The execution of the construction equipment retreat time prediction strategy includes:

[0123] The return of construction equipment includes two methods: sending it out by yourself or sending it back to a designated transport company.

[0124] When the second construction team returns the construction equipment by designated transport units, the midpoint of the time interval selected by the second construction team for the designated transport units to return the equipment is obtained and recorded as the time of returning the construction equipment.

[0125] The execution of the construction equipment retreat time prediction strategy includes:

[0126] When the second construction team returns the construction equipment by sending it out by themselves;

[0127] The time when the second construction team applies to return the construction equipment is recorded as the application time;

[0128] Set the first application time and the second application time. The first application time is on weekdays, and the second application time is on weekends.

[0129] For any one of the first and second application times, the application time is recorded as the marked application time:

[0130] The period from the time of application to the time of returning the construction equipment is recorded as the waiting period for returning the construction equipment;

[0131] Obtain the historical records of the second construction team's retired construction equipment;

[0132] Obtain all historical construction equipment return waiting periods whose application times are marked at the application time in the historical construction equipment return records, and record them as the first historical construction equipment return waiting period, the second historical construction equipment return waiting period, ... the tth historical construction equipment return waiting period;

[0133] Execute the following formula to calculate the average waiting time for construction equipment to be withdrawn;

[0134] (The first historical waiting period for construction equipment withdrawal + the second historical waiting period for construction equipment withdrawal + ... + the tth historical waiting period for construction equipment withdrawal) / t = the average waiting period for construction equipment withdrawal;

[0135] Get the average waiting time for returning construction equipment during the first and second application periods;

[0136] The average waiting time for returning construction equipment during the application time of the second construction team is obtained, and the time between the application time and the average waiting time for returning construction equipment is recorded as the time for returning construction equipment.

[0137] The second construction team's return methods for construction machinery are divided into return by designated transport units and self-mailing. When the second construction team's return method for construction machinery is return by designated transport units, the midpoint of the time period set by the second construction team for the return by designated transport units is obtained to obtain the time for returning the construction machinery; when the second construction team's return method for construction machinery is self-mailing, since the application time and the actual time for returning the power construction machinery vary due to the different habits of each construction team, and are also related to whether the time for applying for return of construction machinery is on a weekday or on 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 and second application time categories, the processed application time is recorded as Mark the application time; obtain all the waiting periods for construction machinery returns with marked application time in the historical records of construction machinery returns, calculate the mean, and obtain the average waiting period for construction machinery returns with marked application time, and then obtain the average waiting period for construction machinery returns for the first category of application time and the average waiting period for construction machinery returns for the second category of application time, obtain the average waiting period for construction machinery returns of the category of application time where the second construction team currently applies, and obtain the time of construction machinery returns. By dividing the application time of construction machinery returns into two categories, the average waiting period for construction machinery returns is calculated in each category, the waiting period for construction machinery returns is calculated more accurately, and the time of construction machinery returns 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.

[0138] The execution of the delivery time determination strategy includes:

[0139] The time when the first construction team makes an appointment to receive the electric construction equipment is recorded as the appointment time;

[0145] The execution of the delivery type determination strategy includes:

[0146] Obtain the type of electric power construction equipment that the first construction team has reserved for use, and record it as the material type;

[0149] Obtain the quantity of electric construction machinery and tools reserved for the first construction team and record it as the material quantity;

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

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

[0152] If a 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 made an appointment to receive electric construction machinery, filter out all third construction teams whose types of returned electric construction machinery are equal to the types of materials, record them as marked construction teams, filter out the construction teams that have returned construction machinery for the third time by the types of materials, get marked construction teams, get the number of returned construction machinery for each marked construction team, get the number of returned construction machinery sets, get the number of materials that the first construction team has made an appointment to receive electric construction machinery, divide the number of returned construction machinery sets 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 of returned construction machinery sets. 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 When there is an element, it means that each element in the combination is less than the material quantity, and the sum of all elements in the combination is equal to the material quantity; when there is a combination, it means that the quantity in the combination can just meet the demand of the first construction team to make an appointment to collect 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 material quantity to obtain the fourth construction team. The fourth construction team can then 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.

[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 unit journey time 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 duration, and record the result as the first delivery duration;

[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 withdrawal group.

[0167] For any combination, obtain any fourth construction team in the combination, obtain the first waiting time based on the time when the fourth construction team returns the construction equipment and the time of appointment for collection, 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] Get the average waiting time of the target construction equipment group;

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

[0175] When the average waiting time is greater than the third waiting time;

[0176] Then, the warehouse address is obtained and sent to each fourth construction team in the target construction equipment return group as the 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 is less than or equal to the third waiting time, the harvest address of the first construction team is obtained and sent to each fourth construction team in the target construction equipment return group as the construction equipment return 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 the 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 equipment to the warehouse. When the average waiting time ≦ the third waiting time, the electric construction equipment returned by the fourth construction team in the target construction equipment 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 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. This provides an in-and-out storage method that can be adjusted by the material warehouse, which is convenient for better management of the in-and-out storage of electric construction equipment and improves the efficiency of in-and-out storage.
