まとめ
この研究では,イランの石油化学産業における安全,健康,福祉の指標の評価のためのVZPLIの拡張方法 (EMA-VZPLI) が導入されています. 新しい方法は,標準のIAM-VZPLIと比較してより正確な評価を提供し,有能なリーダーシップを重要視しています.
科学分野:
- 労働衛生と安全
- 産業工学
- リスク管理
背景:
- 国際社会保障協会 (ISSA) が採用したビジョン・ゼロ (Vision Zero) 戦略は,VZプロアクティブ・リーディング・インジケーター (VZ Proactive Leading Indicators, VZPLI) と呼ばれる14の安全・健康・福祉 (SHW) インジケーターを利用しています.
- これらのVZPLIの評価は,産業における職場の安全と福祉の改善に不可欠です.
研究 の 目的:
- イランの石油化学産業におけるSHW VZPLIの地位を,VZPLIの標準的なISSA評価方法 (IAM-VZPLI) を使用して評価する.
- VZPLIのより正確な評価のために,新しいモデルであるVZPLIの評価のための拡張方法 (EMA-VZPLI) を提案し,検証する.
主な方法:
- この研究では,ベスト・ワースト・メソッド (BWM) と意思決定試験・評価研究室 (DEMATEL) を含む多基準意思決定 (MCDM) のテクニックと,公理的な設計 (AD) を組み合わせた統合的アプローチが採用されました.
- 評価の不確実性を処理するために,これらの方法の中で,躊躇する模糊 (HF) セットが使用されました.
- Hesitant Fuzzy Best-Worst Method (HFBWM) とInterval-Valued Hesitant Fuzzy DEMATEL (IVHF-DEMATEL) を用いて,指標の重みと関係を決定した.
主要な成果:
- 優秀なリーダーシップ (C2) は最も重要な指標で,調達 (C10) は最も重要でない指標でした.
- 能力のあるリーダーシップ (C2) と目に見えるリーダーシップのコミットメント (C1) が依存度が最も高いことを示した.
- 福祉の指標は,調査された石油化学企業の安全と健康の指標よりも弱かったことが判明しました.
結論:
- EMA-VZPLIモデルは,IAM-VZPLIと比較して,石油化学企業のランキングで大きな違いを示した.
- 提案されたEMA-VZPLI方法は,VZPLIを評価するためのより正確で信頼できるアプローチを提供し,それによってVision Zero戦略の有効性を高めます.

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision Making
228
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.

The Availability Heuristic
6.4K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance
154
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...
