Description

Technical Field

[0001] The invention relates to the field of engineering design and construction, and in particular to a method for generating an optimal temporary construction engineering design scheme based on comparison and selection. Background Art

[0002] Temporary construction projects refer to non-permanent buildings, structures and other facilities used for office, living and production that serve the construction project and are built or demolished as the construction project progresses. These facilities are built to meet temporary needs during the construction process. The design plan of temporary construction projects has a vital impact on the construction project and is of great significance to the smooth progress of the construction project. Therefore, there are high requirements for the design plan decision-making of temporary construction projects.

[0003] However, the design plan of temporary construction projects is complex and needs to consider the influence of many factors. Moreover, for the construction of the same project, the construction plan of the temporary construction project is not unique. In the current mature fields and construction enterprise groups, the design plan of temporary construction projects is not unified. When construction projects need to make decisions on temporary construction project plans, there are relatively few high-quality plans that can be referred to, which increases the difficulty of making decisions on temporary construction project plans. At present, the design plan for temporary construction projects usually requires relevant engineering personnel to make decisions, relying on the experience and judgment of construction personnel. It often takes a long time to decide on a temporary construction project construction plan and lacks a visual scientific basis. In addition, the selected temporary construction project construction plan is often not the best, which increases the time and economic costs of the overall project. Summary of the invention

[0004] The purpose of the present invention is to output a temporary construction engineering design scheme that meets the optimization standard based on weight and score comparison, output a temporary construction engineering design scheme suitable for the project to be designed, and provide a method for generating an optimal temporary construction engineering design scheme based on comparison.

[0005] The present invention provides a method for generating an optimal temporary construction engineering design scheme based on comparison and selection, comprising the following steps:

[0006] S1: Collect results through preset solicitation categories, randomly select three categories to solicit from mature fields or enterprises, so that the collected results cover the six categories and obtain temporary construction project design results;

[0007] S2: Perform a global quality control check on the temporary construction project design results obtained in S1, perform an overall score on the temporary construction project design results, screen out the excellent overall results, and then perform sub-item quality control on the overall results to screen out the excellent results

[0008] S3: Input the excellent results into the database, rank and score them in combination with the pre-constructed comprehensive scoring model, and generate a temporary construction project design results database;

[0009] S4: According to the project to be designed, the preferred results are selected from the temporary construction project design results database, and the final weight value of the preferred results is obtained by establishing a matrix. Combined with the ranking score in S3, the final weight value is calculated, and the temporary construction project design plan with the highest final weight value is selected as the output, and the optimal construction plan is output.

[0010] The mature fields or related enterprises mentioned refer to the engineering construction fields and engineering construction enterprises.

[0011] The excellent level refers to the quality level of the preferred solution judged by experts in combination with construction standards.

[0012] Preferably, in step S1, the temporary construction project design results are obtained, and the temporary construction project design results include six categories: project manager's residence, concrete mixing station, T-beam prefabrication yard or railway box beam prefabrication yard, steel bar intelligent processing plant, small component prefabrication yard or pipe segment prefabrication yard, and sand and gravel self-mining processing plant.

[0013] Preferably, step S1 obtains temporary construction project design results, and the collection directions of the temporary construction project design results are randomly selected from three of the six categories, and then collectors in mature fields or related enterprises are allowed to choose from them, so that the collected results cover the six categories as the temporary construction project design results obtained in S1.

[0014] Preferably, step S2 performs a global quality control check on the temporary construction project design results obtained in S1, and the review experts perform an overall score on the temporary construction project design results obtained in S1 according to the construction standards, and screen out the overall results of excellent level.

[0015] The construction standards mentioned above refer to the standards promulgated by the state, including JGJT 188-2009 Technical Code for Temporary Buildings at Construction Sites, GB50720-2011 Technical Code for Fire Safety at Construction Sites of Construction Projects, JGJ 146-2013 Environmental and Sanitation Standards for Construction Projects, JGJT 435-2018 Technical Standards for Modular Facilities at Construction Sites, and standard documents for the formulation of temporary construction project plans within the enterprise.

[0016] Preferably, step S2 performs sub-item quality control on the overall results, and the review experts perform sub-item quality control on the overall results according to the construction standards. The review experts perform sub-item quality control on the overall results according to the construction standards. The categories of sub-item quality control include spatial layout, plane layout, functional division, reasonable process flow, reasonable general layout, sufficient and appropriate site selection basis, accurate and appropriate estimated engineering quantity, reasonable estimated unit cost, appropriate and reasonable estimated total price, and no major omissions or errors. According to the results of sub-item quality control, excellent results are screened out.

[0017] Preferably, in step S3, the excellent-level achievements are ranked and scored in combination with a comprehensive scoring model, and the influencing factors of the comprehensive scoring model are construction period, quality, cost, and safety. The influencing factors of each excellent-level achievement are scored in an arithmetic descending order according to the ranking, and the score range is 100 to 80 points. Assuming that there are N excellent-level achievements, according to the ranking, the influencing factor of the first achievement is 100 points, and the difference in the scores of the influencing factors of subsequent achievements is (100-80) / (N-1). As the number N of excellent-level achievements increases, the ranking score is automatically adjusted, and the excellent-level achievements and the ranking score are input into the temporary construction project design achievement database.

[0018] Preferably, step S4 specifically includes the following steps:

[0019] Establish a selection decision matrix, with i as the vertical direction of the decision matrix, j as the horizontal direction of the decision matrix, and a as the influencing factor of the project to be designed. The influencing factors of the project to be designed should include construction period, quality, cost, and safety. If the project to be designed has special requirements, the influencing factors of the project to be designed can be increased or adjusted, and the influencing factors of the project to be designed are used as the horizontal index a of the decision matrix. i and longitudinal indicators and a j , a ij and a ji The specific weight value of the influencing factors of the project to be designed on the project to be designed is determined by the project personnel. i and a j If the impact on the project to be designed is the same, a ij =1, when a i Than a j When the impact is important ij >1,a ji The calculation formula is:

[0020]

[0021] According to the above a ij and a ji Establish a decision matrix, sum each column of the decision matrix to obtain the sum value of each column, normalize the decision matrix, and its matrix element is the single item value of each column divided by the corresponding sum value of each column to obtain a normalized decision matrix, sum each row of the normalized decision matrix to obtain the final weight value of the influencing factors of the project to be designed on the project to be designed;

[0022] S43: Take the final weight value as the full score, use the comprehensive scoring model to score the preferred results respectively, multiply the ranking score obtained in step S3 by the final weight value, if the project to be designed has special requirements, and the influencing factors of the project to be designed are added or adjusted, then return to step S3 to again rank and score the excellent results in combination with the comprehensive scoring model, wherein the influencing factors of the comprehensive scoring model are the influencing factors of the project to be designed. After obtaining the ranking score, add the result obtained by multiplying it with the final weight value to obtain the final score, and the preferred result corresponding to the highest score in the final score is the optimal construction plan to be selected.
