A method and system for determining analyzing an inventory purchasing opportunity with respect to inventory health. A method may include receiving an offer to purchase units of an inventory item via a purchasing channel for a purchase price per unit; determining a rate of sales demand of the item; and determining a breakeven holding time of existing units of the item, where a cost of holding a unit until the breakeven holding time equals, within an equality threshold, a difference between a sales channel value and the offer purchase price. The method may additionally include determining a healthy inventory level of the item that exceeds a target inventory level by a function of the sales demand rate and the breakeven holding time, and, if a current inventory level of the item exceeds the healthy level, declining to purchase units of said inventory item for the purchase price.

A system provides automatic escalation of demand parameters to determine a reliable demand parameter for a level within a sales hierarchy. The system measures difference in demand parameters between a level of interest within the sales hierarchy and a plurality of other levels within the sales hierarchy. The system also compares the differences in demand parameters of the other levels. The system further determines an escalation path for a demand parameter based on the comparison.

The present invention provides a PDCH channel configuration method and device. The method includes: calculating the single-slot theoretical rate of the cell according to the single-channel rate of the cell and the high coding ratio corresponding to the single-channel rate; Carry out quantitative evaluation of the service perception level to obtain quantitative evaluation parameters; determine the single time slot of the cell according to the first correspondence between the pre-statistical cell traffic value, time delay and single-user single-slot rate, and the quantitative evaluation parameters Demand rate: Calculate the theoretical channel value of the cell according to the multi-slot capability parameters of the terminals in the cell and the number of concurrent terminals within the preset time period; calculate the theoretical channel value of the cell based on the theoretical single-slot rate, single-slot demand rate, and theoretical channel value of the cell , calculating the required channel value of the cell; performing channel configuration of the cell according to the current channel value of the cell and the required channel value. The present invention formulates a PDCH configuration scheme according to the actual situation of the cell, reflecting user perception.

The invention discloses a bus transfer rate control method and device for a communication module. The method comprises the following steps that the communication demand rate of a system or the network connection rate of the communication module is acquired; the bus transfer rate satisfying the communication demand rate of the system or the network connection rate of the communication module is figured out; the transfer rate of a bus connected with the communication module is set to be the bus transfer rate figured out. According to different network use conditions, the rate of the bus is controlled dynamically; under the condition that user usage is not affected, the power consumption of equipment on the bus is lowered, the standby and runtime capacities of the mobile equipment are improved, and user experience is improved; meanwhile, by using the bus transfer rate control method and device, the cost is low.

The invention relates to a sediment oxygen demand (SOD) determination device based on electromagnetic dynamic, and a using method. The SOD determination device comprises a testing room, a dynamic room, a magnetic rotor, a magnetic pole, a motor, a dissolved oxygen probe socket, support fixing interfaces and a storage battery, wherein the testing room is in a cylinder structure with the bottom end opened and the runway-shaped cross section; the dissolved oxygen probe socket is formed on one side of the top of the testing room; the support fixing interfaces are arranged at the two ends of the top of the testing room respectively; the dynamic room is a cylindrical barrel and reversely fixed at the top of the testing room; the motor connected with the magnetic pole is arranged in the dynamic room, and is externally connected with the storage battery by a connecting line; the magnetic rotor is placed in the testing room, and is in magnetic connection with the magnetic pole; a hand-held support is connected and fixed to allow the device to be submerged in water and to be filled with overlying water; the dissolved oxygen probe is inserted and sealed; the device is then fixed at the bottom of the water; overlying water circulation of the testing room is adjusted and controlled; and an SOD is determined. The device is simple in structure, easy to dismount, small and exquisite in size, and convenient to carry, and can effectively determine the SOD under the action of different hydrodynamic forces.
