Win probability estimation model that statistically computes the probability of winning a bid at a given price, and profit optimization models that compute the optimal price for a bid balancing the probability of winning a bid at a price with the profitability of the bid at the given price. In one stage, an expected profit margin of a product may be formulated as a function of its profit margin and win probability to compute its optimal profit margin. In another stage, an expected profit for one or more product accessories may be formulated as a function of the profit margin and their conditional win probability given the server win to compute their optimal profit margins. The conditional win probabilities for the product accessories may be modeled as a function of the utilities of the various purchase options that contain the product and that accessory.

The invention relates to a mass flowmeter for highly precisely measuring mass flow directly. The mass flowmeter comprises two parallel U-shaped measuring tubes with an identical structure, a vibration exciter, two detectors, four fixed distance plates, two flanges, two end connecting tubes, two splitters, a middle connecting tube and a casing. The mass flowmeter provided by the invention has the advantages that the performance and the mechanical quality factor of a resonant sensor are effectively improved, the influence of a flow field is greatly reduced, the mass flowmeter has small flow resistance and low pressure loss and is simple to install and process, the measuring tubes have excellent dynamic balance properties, the mass flow of liquid with high viscosity and high impurity content can be measured, the application range of the Coriolis mass flowmeter is further enlarged, and the requirement of industrial development on the accuracy and the range of flow measurement is met. The mass flowmeter has great promotion effects for saving raw materials, lowering the production cost, reducing environmental pollution, increasing the profit rate and improving the product quality.

The invention discloses an ERP (enterprise resource planning)-based contract reviewing method. Contract reviewing software is used for carrying out simulated stock preparation, simulated scheduling and price reviewing on stock demands of a sales contract (intension): the stimulated stock preparation is used for carrying out contrast and selection on uncompleted contract number, account payable, quality credit and delivery credit of each supplier for the same material through supplier abstracts and determining purchasing intension including current price, purchasing number, and delivery date through a supplier coordination order; the simulated scheduling is used for generating a process scheduling period according to the production period of parts to be machined, and the capacity scheduling is used for displaying equipment name, equipment model, equipment specification, production capability, and equipment numbers in each process selected for a parts process flow, and an adjustment working calendar is used for setting production classes and pre-scheduling periods according to equipment load rates; and the price reviewing is used for generating current cost according to the current price of the simulated stock preparation through product price analysis, the manufacturing cost of salary expense according to the salary standard, and the reviewing price according to the set management expense rate and profit rate.

The invention discloses a process for preparing biomass fuel by using rural town domestic waste and agricultural and forestry waste. The process comprises the steps of step one, waste leachate treatment and foul smell deodorization; step two, waste screening, sorting and coarse crushing; step three, non-organic matter magnetic separation, winnowing and fine crushing; step four, agricultural and forestry waste crushing and screening; step five, stirring of waste combustible materials, agricultural and forestry waste, sludge and water, compression molding, airing and biomass fuel obtaining; andstep six, waste organic matter adding of livestock and poultry manure, and organic fertilizer obtaining. According to the process, the biomass fuel can be directly used in a boiler, and the problem that the livestock and poultry manure pollutes the environment in a livestock farm is solved through the organic fertilizer; for the construction of waste treatment plants, the investment is small, thecost is low, and implementation is easy; the agricultural and forestry waste is collected with paying performed, so that the income of farmers is increased, and the pollution is reduced; the profit rate is high, and operating can last without government subsidy; the waste gas, the waste liquid and the waste residue are subjected to the environmental protection treatment so that new pollution can be avoided.

An electronic money system and a payment-accepting apparatus that further facilitate the use of cards substituting cash money. The electronic money use fee is computed on the basis of the information about the timing with which the amount of money data equivalent to an amount of money used are withdrawn from an information card, thereby allowing the user owning the information card to use an electronic money system regardless of whether time zones having different profit rates. Consequently, the user owning the information card always may pay by the information card, thereby enhancing the effectiveness of the information card that substitutes cash money.

The invention discloses a revenue curve generation method and apparatus, belongs to the field of computers, and aims to provide data support for validity of an operation decision. The method comprises the steps that a noble metal transaction client obtains evaluation time and an evaluation direction input by a user; the noble metal transaction client displays a transaction curve according to the evaluation time and the evaluation direction, wherein the transaction curve contains transaction signals; the noble metal transaction client records transaction details after operations are carried out according to the transaction signals in the transaction curve, wherein each transaction detail comprises a buying price, a selling price, a buying quantity and a selling quantity; the noble metal transaction client calculates revenue data of each transaction, wherein the revenue data comprises at least one of a total fund change situation, a net profit change situation and a profit rate change situation; and the noble metal transaction client displays the transaction data of each transaction in the form of a revenue curve. The method and the apparatus are used for transaction strategy evaluation.
