Techniques are described for automatically analyzing contingencies in information predicting taxi demand. This is to generate representative information regarding current or future taxi demand, and for using such generated representative taxi demand. Contingent demand information may be generated for a variety of types of useful measures of taxi demand rates, such as for projecting expected likelihood of finding a passenger at each of several road locations. Generated representative contingent taxi demand information may be used in various ways to assist taxi and livery service drivers plan optimal routes and schedules. The historical and / or recent contingent demand data may be used to generate the representative traffic flow information. This may include data readings from mobile data sensors in the one or more vehicles, data sensors in or near the roads, or aggregate data sources collected from one or more sensors or through publicly available data sets.

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 method for traffic management and resource allocation on a shared access network including estimating a bandwidth capacity of a gateway, determining a demand rate of an IP gateway, allocating bandwidth to the IP gateway based on the demand rate, traffic priority, or traffic weighting, allocating bandwidth to the IP gateway in advance of demand when excess bandwidth is available, scheduling traffic at the IP gateway based on traffic priority, service plan of a VSAT, or physical layer properties of the VSAT, performing priority queue servicing of traffic at a gateway using a real time traffic priority queue, a non-real time traffic priority queue, two or more modulation and coding queue groups, and a code block queue.

The invention discloses a method for assessing the availability of naval equipment, which includes obtaining the demand rate of equipment maintenance site components at any time; calculating the number of site components under repair according to the component demand rate of the site; and calculating the site components according to the component demand rate of the site The in-transit quantity of parts; according to the parts demand rate of the site, calculate the number of maintenance guarantee delays and transportation guarantee delays of the parts at the site; obtain the supply mean and variance of the parts at the site; calculate the Obtain the expected shortage of parts; calculate the availability of parts based on the expected shortage and variance of parts, combined with the mean and variance of parts supply; and calculate the availability of equipment. The method of the technical solution of the present invention has accurate model algorithm and fast calculation speed, is suitable for establishing a time-varying availability model of equipment at any level, has small errors when the availability is low and the repair probability is high, and has a wide range of applicability.

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.
