Problems solved by technology

This often leads to great uncertainty in the selected index values ​​in terms of engineering scope and compliance with engineering characteristics, which fundamentally affects the accuracy of estimation.
The index data used at the same time is unstructured data, and it is impossible to accurately adjust the index value according to the project requirements (such as the brand and material of the main material) when adjusting the index value. In actual application, only by adjusting the index value Based on experience, adjust the overall coefficient
These reasons seriously restrict the accuracy and reliability of the index method estimation

Abstract

The invention discloses an index fast estimation method comprising the following steps: S1, an index base module acquires data of historical cases, and stores the data in a structured manner to form an index base; S2, a project management module decomposes a proposed project in the form of a tree structure to get a single construction of the proposed project, and stores the data of the single construction in a structured manner; S3, a retrieval module matches an index base for the proposed project according to key content, and gets similar case indexes most similar to the proposed project in the index base through calculation; S4, a storage module stores the data of the similar case indexes in a structured manner; and S5, an estimation adjustment module adjusts the similar case indexes according to the actual situation of the proposed project, and determines the cost indexes of the proposed project. The invention further discloses an index fast estimation system. Case index data sharing and matching and index-based fast evaluation are realized.

Description

technical field [0001] The invention relates to the field of computer information application management, in particular to a method and system for quickly estimating indicators. Background technique [0002] In the early stage of a project, investment estimation is an important basis for program selection and investment decision-making, an important condition for determining the level of project investment, research, analysis, and calculation of economic benefits of project investment, and the basis for correctly evaluating the rationality of construction project investment. The common methods for preparing investment estimates include: production capacity index method, proportional estimation method, coefficient estimation method, index estimation method, etc. Among them, the index estimation method that refers to the cost index of similar projects that have been completed in the past is the most commonly used method. At the same time, the indicator estimation method is re...
