Decision Model Method for the Selection of Lifting Methods for Large Spatial Roof Construction and an apparatus for controlling the same

摘要

The present invention collects the construction method information for the lifting work of the large space roof steel construction, compares the lifting work method of the collected large space roof steel construction, and analyzes the site information of the project construction site information collection and project analysis step (S10) and the step of deriving an influence factor (S20) of deriving an influence factor of the large space roof steel construction lifting work method by extracting and verifying from the information of the roof steel construction construction plan and the construction site for the large space project (S20), and the effect The influencing factors derived in the factor derivation step (S20) are hierarchically structured into upper and lower factors, and for AHP analysis of each influencing factor, the influencing factor AHP analysis request and the effect of the request on the subject side of the survey execution of a preset minimum number or more Influencing factor importance calculation step (S30) in which factor AHP analysis is performed, and the importance of each influencing factor calculated in the factor importance calculation step (S30) and corresponding indicators are collected in the information collection and project analysis step (S10). Site suitability index calculation step (S40) for calculating a site suitability index (SSI) for each of the lifted work methods, and for each lifting work method calculated in the site suitability index calculation step (S40). It provides a decision-making method for selecting a lifting work for a large space roof steel structure, characterized in that it comprises a decision model support method providing step (S50) for selecting and providing an optimized lifting work method from the site suitability index.
