Keywords非線形大域結合写像 / モデル化 / 計測 / 制御 / 社会実験
Research Abstract

eL-Platformにおいて,製品、中間製品、サービスの環境リスク物質排出量の推計値は,組み込まれている原材料や資源・エネルギーを個別に選択して積算されている.分析と制御を行うために,入れ子構造となっている環境リスク物質排出量の積算メカニズムを多数の構成要素が影響を与えあう非線形大域結合写像として捉えて一般的な形でモデル化する必要がある.
本年度に開発されたモデル化と制御の手法については,国際会議において成果の発表がなされ,理論と社会実験の融合に向けた取り組みについて,大いに関心を持たれた.
通常,積上げにおいて,組み込まれる全てのデータが準備されているとは限らないため,環境リスク物質排出量が登録されていない製品,中間製品,サービスが存在する場合,従来のLCAデータの流通プラットフォームでは推計値が求まらないために機能しない.そこで,欠損データに仮の値を設定することとなるが,一般に認証済みの信頼できるデータと欠損データが存在するため推計値の信頼性が保証できない.
本年度において,検証済みのデータや,欠損データが属するカテゴリでの確率・統計的手法により,欠損データの代替値を得る枠組みをシステムに組み込んだ.

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本年度に開発されたモデル化と制御の手法については,国際会議において成果の発表がなされ,理論と社会実験の融合に向けた取り組みについて,大いに関心を持たれた.

Strategy for Future Research Activity

現在,信頼度向上に向けて不確実性と不確定性を取り扱うために,各構成要素に対する合理的な配分のあり方を研究している.シャープレイ値が有力な候補であるように考えているが,リスク評価にあるようなCvarなどの手法も今後,考慮しながら推進していく必要性を感じている.

Expenditure Plans for the Next FY Research Funding

年度末に行った出張の旅費が想定したより少し費用がかからなかったため.
消耗品などの購入に当てる.
