[0002] In today's society, various construction projects often involve numerous stakeholders, including design firms, construction companies, regulatory agencies, and owners. As projects grow in complexity and scale, the question of project responsibility becomes increasingly prominent. Therefore, it's crucial to clearly identify the specific links that lead to quality issues and safety incidents, and identify the individuals responsible. This ensures subsequent quality tracking and accountability.

[0003] How to accurately locate and identify the construction links that cause problems and the relevant construction personnel are important issues that we need to address in depth. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a method and system for determining construction retrospective responsibility based on multi-dimensional analysis.

[0005] The purpose of the present invention can be achieved by the following technical solution: A method for determining construction retrospective responsibility by multi-data fusion analysis, comprising the following steps:

[0006] Step S1: Obtain construction standard data and construction personnel corresponding to each construction stage in the construction project, build a standard responsibility model for each construction stage based on the construction standard data, and build a responsibility chain based on the standard responsibility model for each construction stage and the construction personnel corresponding to each construction stage;

[0007] Step S2: setting architectural problems in the construction project, and setting keywords, impact factors, and impact coefficients corresponding to the architectural problems;

[0008] Step S3: Regularly obtain real-time data of each construction stage, and input the real-time data into the standard responsibility model corresponding to the construction stage to generate an error value;

[0009] Step S4: Set an input port to obtain the problem details input by the user, and obtain the building problem corresponding to the problem details based on the keywords, and mark the building problem as the target problem; if the target problem does not exist, generate an early warning information; generate a accountability group based on the impact factor, impact coefficient, error value and responsibility chain corresponding to the target problem.

[0010] Furthermore, the process of obtaining the construction standard data and construction personnel corresponding to each construction stage in the construction project and constructing the standard responsibility model for the construction stage based on the construction standard data includes:

[0011] The said construction project consists of several construction phases;

[0012] The construction phases include the preliminary preparation phase, the foundation construction phase, the main construction phase and the completion acceptance phase;

[0013] Each construction phase consists of several corresponding construction projects;

[0014] The construction projects corresponding to the preliminary preparation stage include scheme design formulation projects, construction plan formulation projects, construction personnel determination projects, construction material preparation projects, construction site confirmation projects and safety measures confirmation projects;

[0015] The construction projects corresponding to the foundation construction stage include foundation treatment projects, foundation pouring and enclosure stages, and foundation acceptance projects;

[0016] The construction projects corresponding to the main construction phase include beam and column casting and reinforcement projects, reinforced concrete casting and consolidation projects, masonry and wall masonry projects and structural acceptance projects;

[0017] The construction projects corresponding to the completion acceptance stage include completion acceptance projects, document sorting projects and handover projects;

[0018] Generate a serial number according to the construction stage, and generate a sub-serial number of the construction project corresponding to the construction stage according to the serial number;

[0019] For example, if the sequence table of the early preparation stage in the construction stage is marked as "A", then based on the sequence number "A", the subsequence numbers of the construction projects corresponding to the construction stage are generated, that is, the subsequence number of the scheme design formulation project is marked as "A1", the subsequence number of the construction plan formulation project is marked as "A2", the subsequence number of the construction personnel confirmation project is marked as "A3", the subsequence number of the construction material preparation project is marked as "A4", the subsequence number of the construction site confirmation project is marked as "A5", and the subsequence number of the safety measures confirmation project is marked as "A6";

[0020] Obtain construction standard data corresponding to each construction stage, that is, obtain construction standard data corresponding to each construction project;

[0021] The construction standard data includes construction data and document data;

[0022] The construction data is the drawings used to describe the building during the construction process, i.e., construction drawings;

The task item is the name of the relevant license and qualification certificate file, and the task details are the content of the relevant license and qualification certificate file. If the task details do not contain the content of the relevant license and qualification certificate file, the task details are NULL.

[0028] It should be noted that it is normal for the task details to not be NULL.

[0029] Furthermore, the process of building a responsibility chain based on the standard responsibility model of each construction stage and the construction personnel corresponding to each construction stage includes:

[0034] Generate a responsibility code for a construction worker based on his / her work number, appointment date, departure date, and subsequence number of the construction project he / she is responsible for.

[0035] The responsibility code is "JOB_ID+NUM+START_TIME+END_TIME";

[0036] It should be noted that if the responsibility code of construction worker A is queried and construction worker A has not resigned, the resignation time of construction worker A is NULL, that is, END_TIME is NULL;

[0037] It should be further explained that if construction worker B is responsible for two or more construction projects, a corresponding responsibility code will be generated, that is, if construction worker B is responsible for n construction projects, then n corresponding responsibility codes will be generated;

[0039] Obtain the sub-serial number of the construction project corresponding to the sub-standard model, and mark the sub-serial number as the key serial number; obtain the responsibility code whose JOB_ID is equal to the key serial number, and the responsibility code corresponds to the sub-standard model.
