and S3, randomly acquiring adjustable elements to perform random price adjustment until the real-time manufacturing cost is equal to the target manufacturing cost.
From the above description, the beneficial effects of the present invention are: the method comprises the steps of obtaining target construction cost, adjustment parameters, adjustable items and the lowest downward floating rate of unit price of materials set by a user, calculating to obtain the lowest construction cost and the lowest price of all adjustable elements reaching reasonable lowest values, fitting and retracting according to the current price and the lowest price in the adjustment parameters, then randomly obtaining the adjustable elements, and performing random price adjustment to enable the adjusted construction cost to be basically consistent with the target construction cost of the user.

acquiring other adjustable elements except the enterprise management fee and the profit in the adjustable items, arranging the adjustable elements in a price descending manner, and descending the adjustable elements according to the lowest descending rate of the unit price of the material in sequence until the adjustable elements reach a reasonable lowest value;
and taking the price of all the adjustable elements when reaching the reasonable minimum value as the minimum price of each adjustable element, and obtaining the minimum cost according to the engineering quantity and the minimum price of each adjustable element.
From the above description, the reasonable minimum value is the engineering cost obtained by comprehensively considering factors such as construction organization design, quality, construction period, past construction experience of contractors, adoption of new construction technology and the like, and the adjustable elements are floated down by considering the reasonable minimum value and the lowest floating rate set by the user, so as to ensure the rationality of the obtained minimum value.
Further, the step S2 is specifically:
s21, taking the current prices of all adjustable elements in the adjustment parameters as a first group of data, taking the lowest prices of all adjustable elements as a second group of data, generating a first proportion according to the fitting of the first group of data and the second group of data, and floating the lowest prices according to the first proportion to obtain a third group of data;

and S23, circularly executing the step S22 until the real-time construction cost after the floating and the target construction cost are within a preset difference value.
From the above description, it can be seen that the fitting indentation method is adopted to quickly and accurately approach the target manufacturing cost.

in this embodiment, the following are specific: acquiring target manufacturing cost, adjustment parameters, adjustable items and the lowest downward floating rate of the unit price of the material, if the adjustable items comprise enterprise management fees and profits, preferentially adjusting the rates of the enterprise management fees and the profits until the rates reach reasonable minimum values, as shown in fig. 4, the target manufacturing cost of a user is 16808976 yuan, the adjustable items comprise the material, the main material, equipment, the enterprise management fees and the profits, and the lowest downward floating rate of the unit price of the material is 15%;
acquiring other adjustable elements except enterprise management fees and profits in the adjustable items, arranging the adjustable elements in a price descending manner, and carrying out downward floating on the adjustable elements in sequence according to the lowest downward floating rate of unit price of the material until the adjustable elements reach a reasonable minimum value, wherein the adjustable elements are water, bulk cement 42.5 and the like in the graph as shown in figure 4;
taking the price of all adjustable elements reaching the reasonable minimum value as the minimum price of each adjustable element, and obtaining the minimum cost according to the engineering quantity and the minimum price of each adjustable element;
after step S1, if the lowest cost is greater than the target cost, generating and displaying a price adjustment failure prompt message, wherein the price adjustment failure prompt message includes price adjustment failure information, an adjustable cost range of the current project, and whether to apply the lowest cost or select manual price adjustment;
s2, fitting and retracting are carried out according to the current price and the lowest price in the adjusting parameters until the fitted real-time cost and the target cost are within a preset difference value;
in this embodiment, the following are specific:
s21, taking the current prices of all adjustable elements in the adjustment parameters as a first group of data, taking the lowest prices of all adjustable elements as a second group of data, generating a first proportion according to the fitting of the first group of data and the second group of data, and floating the lowest prices according to the first proportion to obtain a third group of data;
s22, judging whether the real-time construction cost after floating is within a preset difference value with the target construction cost, if so, stopping fitting, otherwise, taking out two groups of data closest to the target construction cost from all the data to perform fitting, generate proportion and float according to the proportion;

it should be noted that, during the first stage of uniform floating-down and the second stage of uniform floating-up, there may be some cases where some adjustable elements are the same as the original values of the initial adjustment, i.e. belong to the elements that have not been adjusted in terms of value, for the following reasons: the first stage of floating is influenced by elements, so that the first material can float completely, one quota is reasonable and lowest price, and no floating space exists when other materials of the quota float; while in the second stage, some elements are floated to the original value. Therefore, in the difference compensation stage, the adjustable elements which are not adjusted and the adjustable elements which are adjusted but can be adjusted are filtered out for random adjustment, then the adjustable elements which are not adjusted are subjected to preferential random adjustment, and then the adjustable elements which are adjusted but can be adjusted are subjected to random selection adjustment, so that the reasonability and the difference of the whole bidding scheme are ensured.

That is, step S1 is first floated to the lowest cost, step S2 is then floated to approach the target cost, and finally step S3 is used to complete the difference price.
In this embodiment, if the manufacturing cost of the adjustment parameter is consistent with the target manufacturing cost in step S1, the current price ratio of all the adjustable elements in the adjustment parameter is then randomly oscillated to positive and negative two accuracies, and then a value is randomly selected to replace the current price. Such as: the current price of the adjustable element is 1.00, the ratio is 1.1, the obtained value is 1.00 x 1.1-1.10, the plus and minus precision is oscillated, namely, plus or minus 0.01 is added to obtain three values of 1.09,1.10 and 1.11, and one of the three values is randomly selected to replace 1.00.
In this embodiment, as shown in fig. 2, the adjusted control price data is set aside, the data of the original "volume price column" in the project is the bid control price, the bidder adjusts the target price on the basis of the bid control price, and after obtaining the target price, the bidder compares the target price with the bid control price conveniently.
In this embodiment, as shown in fig. 3, according to the bidding document requirement, locking is performed for the non-adjustable part of the fee during the adjustment process. As shown in fig. 3, the variable FBFXHJ-SBHJ + DJCSHJ in the calculation formula in the row named safe civilization construction cost is converted into a numerical value by back calculation, so that the cost is fixed, and the back calculation mode is as follows: the control price amount is divided by the rate and multiplied by 100 to obtain the value, namely 100 × 118356/2.27 in fig. 3 is 5213920.7.
In this embodiment, the target cost includes not only the direct input of the user, but also the calculation and application after the input of the K value in the calculator, wherein the K value of each bidding unit is determined by the bidding document request randomly drawn by the electronic trading platform or randomly drawn at the bidding site.
In addition, since the user adjusts the price in the project bidding process, the price for each element does not exceed the original value in principle, that is, the price does not exceed the original value in either the floating in step S2 or the random adjustment in step S3.

s31, judging whether the real-time construction cost is the same as the target construction cost, if so, storing the adjustment scheme of the real-time construction cost finally obtained in the step S2, otherwise, judging whether the adjustable elements capable of being continuously adjusted exist, if not, storing the adjustment scheme of the real-time construction cost finally obtained in the step S2, and if so, randomly obtaining an adjustable element from all the adjustable elements capable of being continuously adjusted and carrying out random price adjustment;
s32, judging whether the adjusted adjustable element and the corresponding price meet the project cost limit condition, if yes, saving the adjustment and calculating to obtain the real-time cost after the adjustment, otherwise, abandoning the adjustment and marking the adjustable element as unadjustable;
s33, repeating the step S31 and the step S32 until the real-time construction cost is the same as the target construction cost or the adjustable element which can be continuously adjusted does not exist.
10. The project bid-based one-touch bidding terminal according to any one of claims 6 to 9, wherein when executing the step S1 in the computer program, if the manufacturing cost of the tuning parameter is consistent with the target manufacturing cost, the processor randomly selects a value to replace the current price after randomly oscillating the current price ratio of all tunable elements in the tuning parameter to plus or minus two accuracies.
