Abstract: A replenishment quantity determination method and apparatus, a device, a storage medium, and a program product are provided. The method comprises: obtaining the inventory information of a warehouse and the product information of a product stored in the warehouse, and determining a target product; determining a total inventory quantity according to a substitution chain to which the target product belongs; determining a target inventory quantity and an inventory lower limit value according to the product information; if the total inventory quantity is less than the inventory lower limit value, and the inventory usage form of each product in the substitution chain comprises a bidirectional usage relationship, determining a replenishment ratio of the product; and according to each replenishment ratio, the target inventory quantity, and the total inventory quantity, determining the replenishment quantity of each product having the bidirectional inventory usage relationship in the substitution chain.

Abstract: A material conveying method, device and system and a storage medium. The method specifically includes: first determining a target conveying route from a plurality of candidate conveying routes according to a route planning model; then generating a conveying instruction according to the target conveying route and user order information; and finally sending the conveying instruction to a conveying device to enable the conveying device to convey a material from a source node of supply to a user node via the target conveying route, where the candidate conveying routes refer to routes from a source node of supply to a user node via at least one candidate warehouse. The present method can realize warehouse route planning and material transportation control.

Abstract: A route determination method, apparatus, server, and storage medium for cold chain distribution, and the method includes: receiving a route determination request from a terminal device, where the route determination request includes: location information of each customer point in a set of customer points to be distributed and location information of a distribution center (21); determining at least one target distribution route according to the location information of each customer point in the set of customer points to be distributed, the location information of the distribution center, scenario constraints and transportation cost constraints (22); and pushing the at least one target distribution route to the terminal device (23).

Abstract: Disclosed are a digitized automatic control method for oil-pumping and a digitized balance-shifting pumpjack, said pumpjack comprising a main motor (15), a decelerator (8), a crank (9), a connecting rod (6), a walking walking beam (3), a balance arm (7), a derrick (5), a horsehead (2), a substructure (12), brake device (13), a beam hanger (1), a load sensor (17), a stroke process measurer, a safety stop device, and a digitized control box (14). A movable counterweight box (28) moves leftward and rightward on the balance arm (7), automatically balancing load at the suspension center in various operating conditions, and pumpjack's frequency of stroke is automatically adjusted according to variations in pump fullness. Features include safety and reliability, convenience of operation, enhanced oil well production, balance rates, energy conservation and consumption reduction.
