• for each item of all items, determining, based on shipment dates and shipment quantities corresponding to the shipment dates of the item, a shipment interval duration between consecutive two shipments of the item, and updating the shipment interval duration to shipment quantity-associated information of the item, wherein the shipment quantity-associated information comprises the shipment dates and the shipment quantities;
• determining at least one to-be-processed item from the all items based on shipment quantity-associated information of the all items, wherein each to-be-processed item of the at least one to-be-processed item is an item whose shipment frequency is less than a preset threshold;
• for each to-be-processed item of the at least one to-be-processed item, determining a replenishment attribute value of the to-be-processed item based on a current time and shipment quantity-associated information of the to-be-processed item, wherein the replenishment attribute value is used to represent urgency of replenishment of the to-be-processed item at the current time;
• in response to the replenishment attribute value of the to-be-processed item being greater than a preset replenishment attribute threshold, determining the to-be-processed item as a target to-be-processed item, and determining a target inventory quantity of the target to-be-processed item based on the replenishment attribute value of the target to-be-processed item and a target inventory quantity determination model;
• and
• for the target to-be-processed item, determining a target replenishment quantity of the target to-be-processed item based on the target inventory quantity and a net inventory quantity corresponding to the current time of the target to-be-processed item;
• wherein in a case where the shipment quantity-associated information comprises at least one shipment interval duration, the determining at least one to-be-processed item from the all items based on shipment quantity-associated information of the all items comprises:
• for each item of the all items, determining a variation coefficient of the item based on the at least one shipment interval duration corresponding to the item, wherein the variation coefficient is used to represent fluctuation of the at least one shipment interval duration, and the at least one shipment interval duration and the shipment interval duration between the consecutive two shipments are comprised in a set of shipment interval days corresponding to the item;
• and
• determining the at least one to-be-processed item based on a preset variation coefficient threshold and the variation coefficient of the item;
• wherein the determining a replenishment attribute value of the to-be-processed item based on a current time and the shipment quantity-associated information of the to-be-processed item comprises:
• determining a target data processing method based on the shipment quantity-associated information of the to-be-processed item;
• and
• processing the current time and the shipment quantity-associated information based on the target data processing method to obtain the replenishment attribute value of the to-be-processed item;
• wherein the determining a target data processing method based on the shipment quantity-associated information of the to-be-processed item comprises:
• determining the at least one shipment interval duration based on shipment quantities corresponding to all shipment dates in the shipment quantity-associated information;
• in a case where the at least one shipment interval duration satisfies a preset uniform distribution, determining the target data processing method to be a mean estimation method;
• and
• in a case where the at least one shipment interval duration does not satisfy the preset uniform distribution, determining the target data processing method to be a quantile estimation method.

A non-transitory storage medium storing a computer-executable instruction, wherein the computer-executable instruction, when being executed by a computer processor of at least one of a server and a terminal device, is used to perform a method for controlling item inventory;

• wherein the method for controlling item inventory comprises:
• for each item of all items, determining, based on shipment dates and shipment quantities corresponding to the shipment dates of the item, a shipment interval duration between consecutive two shipments of the item, and updating the shipment interval duration to shipment quantity-associated information of the item, wherein the shipment quantity-associated information comprises the shipment dates and the shipment quantities;
• determining at least one to-be-processed item from the all items based on shipment quantity-associated information of the all items, wherein each to-be-processed item of the at least one to-be-processed item is an item whose shipment frequency is less than a preset threshold;
• for each to-be-processed item of the at least one to-be-processed item, determining a replenishment attribute value of the to-be-processed item based on a current time and shipment quantity-associated information of the to-be-processed item, wherein the replenishment attribute value is used to represent urgency of replenishment of the to-be-processed item at the current time;
• in response to the replenishment attribute value of the to-be-processed item being greater than a preset replenishment attribute threshold, determining the to-be-processed item as a target to-be-processed item, and determining a target inventory quantity of the target to-be-processed item based on the replenishment attribute value of the target to-be-processed item and a target inventory quantity determination model;
• and
• for the target to-be-processed item, determining a target replenishment quantity of the target to-be-processed item based on the target inventory quantity and a net inventory quantity corresponding to the current time of the target to-be-processed item;
• wherein in a case where the shipment quantity-associated information comprises at least one shipment interval duration, the determining at least one to-be-processed item from the all items based on shipment quantity-associated information of the all items comprises:
• for each item of the all items, determining a variation coefficient of the item based on the at least one shipment interval duration corresponding to the item, wherein the variation coefficient is used to represent fluctuation of the at least one shipment interval duration, and the at least one shipment interval duration and the shipment interval duration between the consecutive two shipments are comprised in a set of shipment interval days corresponding to the item;
• and
• determining the at least one to-be-processed item based on a preset variation coefficient threshold and the variation coefficient of the item;
