Research on the evaluation method of whole process engineering consulting service modes based on uncertain...

Area of Science:

• Engineering Management
• Decision Science
• Artificial Intelligence

Background:

• The engineering construction industry demands comprehensive consulting services beyond single-stage support.
• Current engineering consulting services in China often lack lifecycle planning and control.
• Optimizing fixed asset investment and construction management requires integrated, whole-process solutions.

Purpose of the Study:

• To develop a scientific framework for evaluating whole process engineering consulting service modes (ECSM).
• To enhance multiple-attribute group decision-making (MAGDM) techniques for complex evaluations.
• To improve project quality and economic benefits through optimized decision-making.

Main Methods:

• Development of the interval neutrosophic number TODIM-MACONT (INN-TODIM-MACONT) technique for MAGDM.
• Application of interval neutrosophic sets (INSs) to manage fuzzy information in evaluations.
• Utilizing Information Entropy for weight determination under INSs.

Main Results:

• The INN-TODIM-MACONT technique effectively addresses MAGDM problems within INSs.
• Enhanced TODIM and MACONT techniques provide a robust framework for complex evaluations.
• A numerical analysis validated the proposed technique's efficacy in whole process ECSM evaluation.

Conclusions:

• The proposed INN-TODIM-MACONT technique offers a superior approach to whole process ECSM evaluation.
• This method significantly improves scientific decision-making in fixed asset investment and construction management.
• The study contributes a novel technique for optimizing project outcomes in the engineering consulting sector.
