Description

Technical Field

[0001] The invention relates to the technical field of information prices of materials and machinery, and in particular to a method for publishing information prices of materials and machinery for construction projects. Background Art

[0002] Labor, materials and machinery are collectively referred to as labor, materials and machinery consumed or used in construction projects. The information prices published by the Cost Station Information Price Journal are the guiding prices for the main labor, materials and machinery required for construction projects. They are an important reference for the entire engineering industry practitioners to make estimates, budgets, bidding, tenders, contracts, settlements, final accounts and other engineering costs. The scientific rationality, authenticity and reliability of its prices are of great significance to the stability of the entire industry, and are also the basis for government financial investment evaluation and audit review. However, there are thousands of information prices for labor, materials and machinery published every month, and the quotations for labor, materials and machinery in various regions vary depending on the level of economic development. The result is that the monthly information price release is not only time-consuming and labor-intensive, but also untimely. In addition, the price sources of some labor, materials and machinery quotations are not close to the truth, that is, there are outliers, which leads to many doubts about the rationality of the information prices.

[0003] At present, the compilation and release of information prices usually involves the staff of the cost station sending letters to invite suppliers to quote, manually summarizing quotations, multiple people calculating to compile information prices, applying for leaders to review information prices offline, and finally uploading and publishing the information prices on official websites or journals. The above-mentioned existing technologies have the following technical problems: (1) The existing technologies can only manually collect quotations for materials and machinery, resulting in incomplete market quotations and a waste of manpower and time; (2) There are many information prices to be released, and manual summarization and calculation are time-consuming and labor-intensive; (3) Offline review cannot respond quickly, which ultimately delays the release of information prices by more than one month, making it difficult to timely reflect and guide the real price changes in the materials and machinery market.

BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 The present invention is a flowchart of the steps of a method for publishing information prices of construction project materials and machinery. DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The present invention provides a method for publishing information prices of construction engineering materials and machinery, comprising the following steps:

[0055] S1. Collect quotations of materials and machinery from multiple suppliers through the preset information template of materials and machinery.

[0056] Preferably, in step S1, a labor, material and machinery information template is preset through an Excel spreadsheet; the labor, material and machinery information template includes the name, specification, classification, unit, quotation, type and other labor, material and machinery related information; wherein, the above classification specifically refers to the international classification of labor, material and machinery, the labor, material and machinery information template includes a variety of international classifications of labor, material and machinery, and the automatic classification standards for labor, material and machinery are complete. By applying automatic coding technology, labor, material and machinery can be standardized.

[0057] In step S1, the information template of materials and machinery is pushed to multiple suppliers in the market of materials and machinery on a monthly or quarterly basis; further, the suppliers download the information template of materials and machinery, fill in the information template of materials and machinery, and upload the information template of materials and machinery in batches, thereby collecting the quotations of materials and machinery from multiple suppliers. The above-mentioned information template of materials and machinery can be pushed to one or more different platforms related to quotation of materials and machinery: for example, different platforms related to quotation of materials and machinery such as Cost Pass and Price Inquiry and Purchasing Platform, and also platforms related to quotation of materials and machinery in different regions.

[0058] In addition, step S1 also includes: automatically aggregating the collected quotations for labor, materials and machinery, and automatically aggregating all quotations for labor, materials and machinery separately, for example, aggregating the quotations for labor, materials and machinery corresponding to the same type of labor, materials and machinery into the same data set, and so on.

[0059] S2. Calculate the price of labor, materials and machinery quotations to obtain the calculated price of labor, materials and machinery: by setting the required conditions such as price source and calculation method, automatically start batch calculation of the collected and summarized labor, materials and machinery quotations to generate the draft price for compiling the information price, i.e. the calculated price.

[0060] Specifically, in step S2, the price of materials and machinery quotations can be calculated by the arithmetic average method. The arithmetic average method is suitable for price calculations with a large number of collected and summarized materials and machinery quotations and relatively small price deviations. By screening out abnormal materials and machinery quotations to obtain a reasonable calculated price, the rationality of the information price compiled later can be better guaranteed. Among them, the arithmetic average method includes the following sub-steps:

[0061] S21 a. Sort a group of quotations for labor, materials and machinery from low to high to obtain a quotation array a: a = (x1, x2, x3..., xn), where x is the quotation for labor, materials and machinery, and n is the number of quotations for labor, materials and machinery in the group.

[0062] S22a. Calculate the first quotation sample interval by the following formulas (1)-(8):

[0063] q1=Integer part of (n+1) / 4 (1)

[0064] q3=Integer part of 3(n+1) / 4 (2)

[0065] w1=decimal part of (n+1) / 4 (3)

[0066] w3=decimal part of 3(n+1) / 4 (4)

[0067] Q1=(1-w1)*xq1+w1*x(q1+1) (5)

[0068] Q3=(1-w3)*xq3+w3*x(q3+1) (6)

[0069] IQR=Q3-Q1 (7)

[0070] The first quotation sample interval = [(Q1-k*IQR), (Q3+k*IQR)] (8)

[0071] In the above formula (5), xq1 represents the corresponding order of the price of the materials and machinery in the quotation array a; in the above formula (8), k is the interval rationality coefficient, the value range of k is (0, 100), and the default value of k is 1. For example, a group of material and machinery quotations (i.e., the quotations of different suppliers for the same material and machinery) includes a total of 20 material and machinery quotations, then the above n = 20, correspondingly, q1 = 5, w1 = 0.25, xq1 corresponds to the fifth material and machinery quotation x5 in the quotation array a, and the same is true for xq3.

[0072] The first quotation sample interval is calculated by the above formulas (1)-(8) to screen out abnormal labor, material and machinery quotations with large deviations in the quotation array a, so as to better ensure the rationality of the information price compiled subsequently.

[0073] S23a, selecting the labor, material and machinery quotations in the first quotation sample interval in the quotation array a to obtain reasonable quotation samples and remove abnormal values ​​in the quotation array a.

[0074] S24a, calculate the average value A1 of the reasonable quotation samples by the following formula (9):

[0075] A1=∑cm / m (9)

[0076] In the above formula (9), c is the price of labor, materials and machinery of the reasonable quotation sample, m is the number of quotations of labor, materials and machinery included in the reasonable quotation sample, and the average value A1 of the reasonable quotation sample is the estimated price of labor, materials and machinery calculated by the arithmetic average method.

[0077] In addition, in step S2, the price of materials and machinery quotations can also be calculated by the normal distribution method. The normal distribution method is suitable for price calculations with a large number of collected and summarized materials and machinery quotations and relatively large price deviations. By screening out abnormal materials and machinery quotations to obtain a reasonable calculated price, the rationality of the information price compiled subsequently can be better guaranteed; wherein, the normal distribution method includes the following sub-steps:

[0078] S21 b. Select reasonable quotation samples through the above arithmetic average method.

[0079] S22b. Calculate the second quotation sample interval by the following formulas (10)-(12):

[0080]

[0081] Second quotation sample interval = [y1, y2] (12)

[0082] Among them, u is the sample mean of the reasonable quotation sample, σ is the sample standard deviation of the reasonable quotation sample, the value range of X is [0.9, 0.95], and the value of X is preferably 0.9. The above y1 corresponds to the pre-interval value, and y2 corresponds to the post-interval value. y1 and y2 are calculated by the inverse function formula of the normal distribution Calculated.

[0083] S23b. Select the quotations for labor, materials and machinery in the second quotation sample interval in the quotation array a to obtain a new reasonable quotation sample. It can be understood that the new reasonable quotation sample is the quotation sample after eliminating the abnormal quotations for labor, materials and machinery with relatively large price deviations in the quotation array a.

[0084] S24b, calculate the average value A2 of the new reasonable quotation sample by the following formula (13):

[0085] A2=∑dM / M (13)

[0086] In the above formula (13), d is the price of labor, materials and machinery of the new reasonable quotation sample, M is the number of quotations of labor, materials and machinery included in the new reasonable quotation sample, and the average value A2 of the new reasonable quotation sample is the estimated price of labor, materials and machinery calculated using the normal distribution method.

[0087] In addition, in step S2, the price of the materials and machinery quotations can also be calculated by the weighted average method. The weighted average method is applicable to the situation where the collected and summarized materials and machinery quotations have multiple different price sources, and the quotations of materials and machinery from different price sources have relatively obvious differences. Different price sources are given different weights by the weighted average method, so as to solve the differences in the quotations of materials and machinery from different price sources to obtain a reasonable calculated price, thereby better ensuring the rationality of the information price compiled subsequently; wherein, the weighted average method includes the following sub-steps:

[0088] S21 c. For the quotations of materials and machinery from different price sources, the average values ​​of each reasonable quotation sample are calculated by the above-mentioned arithmetic average method. Among them, different price sources can refer to the quotations of materials and machinery collected by the above-mentioned materials and machinery information template uploaded to each platform related to materials and machinery quotation. It can be understood that the quotations of materials and machinery collected by the same platform are regarded as the same price source; or different price sources can also refer to the quotations of materials and machinery from suppliers in different regions. It can be understood that the quotations of materials and machinery collected from suppliers in the same region are regarded as the same price source.

[0089] S22c. Calculate the weighted average value Aw using the following formula (14):

[0090] Aw=Pa′*Wa′+Pb′*Wb′+...+Pn′*Wn′ (14)

[0091] In the above formula (14), Pa' is the average value of the reasonable quotation samples of price source a', Pb' is the average value of the reasonable quotation samples of price source b', Wa' is the weight of price source a', and Wb' is the weight of price source b'; Wa'+Wb'+...+Wn'=1, that is, the sum of the weights of all price sources is 1, and the weighted average value Aw is the estimated price of labor, materials and machinery calculated by the weighted average method. Preferably, the more the number of labor, materials and machinery quotations included in the reasonable quotation samples of a certain price source, the greater its corresponding weight.

[0092] S3. Compile the estimated price according to the information price compilation conditions to obtain the information price of labor, materials and machinery: that is, according to the information price compilation conditions, automatically start batch compilation of the draft price (i.e. the estimated price) of the calculated information price to generate the information price for review.

[0093] Specifically, the conditions for compiling information prices may include tax rates, insurance premiums, draft price fluctuations, custom prices or compilation time, etc.

[0094] In step S3, the calculated price is compiled according to a certain information price compilation condition: for example, the calculated price is compiled according to the tax rate: information price = calculated price * (1 + tax rate); or, the calculated price is compiled according to the procurement premium: information price = calculated price + procurement premium; or, the calculated price is compiled according to the fluctuation of the manuscript price: information price = calculated price * (1 + the fluctuation rate of the manuscript price of this period relative to the manuscript price of the previous period); or, the calculated price is compiled according to the custom price: information price = calculated price + custom price.

[0095] In addition, in step S3, the calculated price can also be compiled based on the combination of multiple information price compilation conditions: for example, the calculated price can be compiled based on the two information price compilation conditions of tax rate and insurance premium: information price = calculated price * (1 + tax rate) + insurance premium; or, the calculated price can be compiled based on the two information price compilation conditions of manuscript price fluctuation and insurance premium: information price = calculated price * (1 + the fluctuation rate of the manuscript price of this period relative to the manuscript price of the previous period) + insurance premium.

[0096] S4. Review the information price through online review. Specifically, the information price compiled in the above step S3 can be pushed to the user end of the reviewer, so that the reviewer can review online whether the information price is reasonable and true. If so, the review is passed.

[0097] S5. The approved information price will be released to the public according to the release conditions.

[0098] Specifically, the publishing conditions may include publishing time, information price journal and / or publishing platform; for example, the publishing time may be set to the first day of each month to achieve scheduled publishing of information prices, the information price journal may include information price journals of different types of materials and machinery, and the publishing platform may include publishing platforms in different regions.
