Outline of Research at the Start

本研究はライフラインネットワークのモデル化に利用されている交差グラフに属する数種のグラフを対象に,最大影響度,および,最大迂回度要節点問題を解く効率的アルゴリズムを開発することを目的とする.これにより,コストパフォーマンスの高いメンテナンスによる大規模ライフラインネットワークシステムの安定性,信頼性向上への応用が期待でき,災害に強いネットワーク構築の支援となる.
1:台形グラフにおける最大迂回度要節点問題を解く効率的アルゴリズムの開発.
2:区間グラフにおける最大影響度要節点問題を解く効率的アルゴリズムの開発.
3:置換グラフにおける最大影響度要節点問題を解く効率的アルゴリズムの開発.

Outline of Final Research Achievements

We have developed the following graph algorithm that can be applied to the robustness of network operation.
An O(n^2) time algorithom for the influential hinge vertex problem on interval graphs; An O(n^2) time algorithm for the vertex connectivity problem on circular trapezoid graphs; An O(n^2) time algorithm for the all-pair shortest path problem on circular trapezoid graphs, An O(n^2) time algorithm for the detour hinge vertices of circular-arc graphs.

Academic Significance and Societal Importance of the Research Achievements

近年,日本は地震,台風などの自然災害が続出していることから,ライフラインネットワークの災害耐性,頑健性の向上が急務となっている.交差グラフ上の最大迂回度要節点問題や最大影響度要節点問題を解くアルゴリズム開発により,ネットワーク伝達において最も重要となる設備の識別が可能となる.これらの設備に対して稼働率を向上させることで,コストパフォーマンスの高いライフラインネットワークの頑健化,安定化が実現可能となる.本研究は,災害耐性強化を目的としたグラフ理論アプローチによるライフラインネットワークの頑健化に寄与するグラフアルゴリズムの開発を目的とする.
