Key Points

  • The aim is to analyze and visualize information flow throughout the lifecycle of infrastructure projects to enhance productivity and decision-making.
  • Constructed a structural model focusing on information input and output in highway paving processes.
  • Extracted all generated and utilized information related to the project.
  • Created a management OD table for visualizing information flow.
  • Applied association analysis for quantitative evaluation of information flow.
  • Compared information flow under different project states to identify areas for improvement.
  • Visualized information flow within the paving project, revealing existing communication issues.
  • Highlighted potential for improved information utilization in infrastructure management.
  • Identified key areas for priority improvements in current project structures and information links.

Abstract

インフラ分野のdxを通じて，業務の生産性向上や意思決定の高度化を実現するためには，事業構造の分析や事業で利用・生成される情報の可視化が不可欠である．本研究では，高速道路舗装を対象として，ライフサイクルを形成する事業プロセスに対し，情報の入出力に注目した構造モデルの作成および利用・生成される全ての情報の抽出を行い，マネジメントod表を構築した．これにより，舗装事業における情報フローを可視化し，現状の情報連携の課題と，さらなる情報利活用の可能性を明らかにした．さらに，アソシエーション分析を適用し，情報フローの定量的評価を行った．異なる事業状態を想定して情報フローを比較することにより，現状の事業構造や情報連携における優先的な改善箇所を明示した．
