Example 3
Data matching module algorithm model
And the data matching module is used for performing data matching on the approximate calculation list and the purchase list input into the data matching pool. First-stage matching is carried out, if automatic matching is successful, the matching is stored in a matching success table, if the matching is not successful, identification is carried out and temporarily stored in a matching buffer area, manual intervention adjustment is carried out, data after the matching is successful again enters second-stage matching, until complete matching is achieved, the complete corresponding relation between the approximate calculation and the purchase list is established, and the data are transmitted to an early warning management module.
The general calculation list and the purchasing list of the construction project in the metallurgical industry are respectively detailed in a building installation expense list (building installation expense list for short) and an equipment list and separately purchased. The list of the building and installation expenses is generally prepared by using 'valuation rules of a metallurgical industry construction engineering quantity list (2013 edition)', and the specification of the list is a national industry standard and is an industry standard observed by design houses, construction units and construction units. In the pricing rule of the metallurgy list, the serial number of the standard list is 12-bit code, and the equipment list has no relevant national standard.
Based on the analysis of the actual situation of the list data, the list of the installation cost of the building and the list of the equipment are considered separately when a matching algorithm is designed.
General principle of building installation fee list matching: if the list code exists, the hierarchical matching is carried out by using 9 bits (the stream code is removed from 12 bits, and the last 3 bits are the stream code), 6 bits and 4 bits in sequence according to the list code, and the accurate matching is firstly carried out, and then the fuzzy matching is carried out. If no list code exists, the list is matched accurately according to the list name, the item characteristics and the unit, and then fuzzy matching is carried out. The exact match according to the list name, item feature and unit means that the list name, item feature and unit are completely equal. The fuzzy matching means that the word segmentation scores according to the weight through a fuzzy matching algorithm, and the highest scoring pair is used as a matching item. See in particular the description of the fuzzy matching algorithm below.
When matching, matching the approximate calculation list with the purchase list, wherein logically, four matching relations exist: one procurement list corresponds to one approximate calculation list (one-to-one for short), one procurement list corresponds to a plurality of approximate calculation lists (one-to-many for short), a plurality of procurement lists correspond to a plurality of approximate calculation lists (many-to-many for short), and one procurement list does not find the corresponding approximate calculation list (no matching for short). The corresponding standard is as follows: if the first 9 digits of the numbering are completely the same, the correspondence is judged.
If the matching is one-to-one or one-to-many, the program judges that the matching is successful.
If the condition is many-to-many, the list name, unit and item characteristics are required to be added in sequence, so that the condition of more accuracy is used for finally converting the many-to-many into one-to-one or one-to-many successful matching.
The characters of the measurement units are different and have the same meaning, and standardized treatment is firstly carried out, such as treatment according to ton, T, T and 1000 KG.
The method for managing the engineering quantity list data matching and the overgross calculation early warning of the metallurgical engineering project solves the problem of the association loss of the procurement engineering quantity list and the gross calculation engineering list data through a matching algorithm, reconstructs the association relation, realizes the comparative analysis of the procurement winning engineering quantity, the unit price and the gross calculation engineering quantity list, and achieves the real-time and dynamic overgross calculation early warning and overlimit early warning, thereby achieving the aim of fine management of cost control.
