Embodiment 1

[0034] The BIM software commonly used throughout the life cycle of the building is distributed to each level of the functional area according to the design stage, so that each link corresponds to the corresponding software library.

Embodiment 2

[0036] Statistics the attenuation value of the model in the entire project connected to the software at the same level by the superior software, that is, the attenuation value of the downward propagation from the superior functional area The superior software and the subordinate software that connect each decay value are connected to form a design node, so that every two software that occurs in the flow of information corresponds to a unique attenuation value.

Embodiment 3

[0038] Write a permutation combination algorithm to freely combine the attenuation value of different lists, a total of m combination methods are generated, and the sum of the combined attenuation value and Lt are: where t∈ [1,2,... m], m of attenuation value and embedding in the new list for sorting processing.

Abstract

The invention discloses a BIM information flow minimum attenuation path calculation method based on weight free combination, and the method comprises the steps: 1, classifying the whole life cycle process of a building according to functions, and distributing common BIM software to each stage of functional region; step 2, counting an attenuation value of the model in the whole project accessed from the upper-level software to the current-level software; step 3, marking attenuation values between the software when the model information is spread, generating a plurality of empty lists according to stages, and embedding the attenuation values with the same inheritance relationship into the same list; and step 4, permutation and combination are carried out on the attenuation values among the plurality of lists, and the path with the lowest sum of the attenuation values and the path with the lowest attenuation value are obtained. According to the method, inheritance attenuation values among mainstream BIM software in the industry are subjected to overall statistics, the BIM information flow path with the lowest attenuation value is optimized through free combination of the inheritance attenuation values, and a series of problems caused by key parameter loss in the process that current software inherits an upstream model are solved.

Description

Technical field [0001] The present invention belongs to the technical field of construction BIM life cycle work, specifically relates to a minimum attenuation path calculation method based on the free combination of attenuation value bim information flow. Background [0002] BIM is short for Building Information Modeling Building Information Modeling, which is a new method of building life cycle management, which can provide a basic model for the life cycle operation and maintenance of buildings. With the promotion of digital innovation in the construction industry in various countries, BIM's software system is becoming more and more perfect, but the software that can achieve similar functions has a high repetition rate. [0003] Attenuation value is an important measure of the completeness of the expression model in the BIM information flow, which can intuitively reflect the minimum attenuation path of the information flow in the model inheritance of the software chain.
