SSAPTI: Synergistic Sustainability Assessment of Passenger Transport Interiors

The present framework implements a simplified LCA method titled SSAPTI for assessing passenger transport cabin interiors using the synergistic application of MCDA and LCA approaches. This framework uses a sequenced process flow to translate cabin product data into a set of impacts based on a combination of objective product material data and subjective expert judgements regarding the life cycle and strategic importance of the products assessed to the user's organisation. The following set of sheets constitutes the presented framework: - "c1. Cabin Inventory": offers the space for detailed product data records, which include material and weight identification for each product component. - "c2. Sustainability Assessment": used as the central space for integrating quantitative assessment elements: sustainability impact of cabin materials, impact category weights, circularity effects. - "c3. Circular Economy": provides the space to model the circular scenarios of cabin product life cycle. - "c4. Qualitative LCA": facilitates qualitative assessment of cabin product life cycle activities based on expert judgement since SSAPTI use cases presume objective life cycle data unavailable. - "c5. Strategic Criteria": uses expert judgement to qualitatively assess the importance of each cabin product for the business using non-technical criteria to adjust priorities. - "c6. Results Aggregation": the central space where the interim results from each assessment block are pulled into a single final score for each product reflecting its sustainable priority level. - A set of supporting sheets that enable the 6 core sheets: -- "s1. LCIA Method Selection": a summary of relevant LCIA method features informing the decision about its inclusion in this framework. -- "s2. IC Generalisation": provides the reference to IC organisation where several IC used by the individual methods are merged into one general IC to enable method comparability. -- "s3. Importance Weighting": derivation of the importance weights for both the individual IC and qualitative LCA stages using MCDA. -- "s4" sheets provide the space for importing the normalised outputs from selected LCA databases (EcoInvent is used for SSAPTI) and selected LCIA methods. Each sheet houses a single method and the associated MCDA-based functionality for transforming the raw LCA database outputs into relative cabin product impacts based on material weights. -- "s5. Method Comparisons": offers the comparison between all included LCIA methods per each IC to inform the user's prioritisation strategy. -- "s6. Qualitative Evaluation": contains the functional block performing the analysis for Qualitative LCA and Strategic Criteria sheets; is not intended for user's review or amendment. -- "s7. References" outline the list of sources used throughout this framework. The presented sheets may be used as information source, or be amended by the user to reflect the needs of their specific project. Amendments may be performed in the cells containing blue text on yellow background only, which applies to all sheets in this framework. Any sheets that do not contain blue text on yellow background shall not be amended.本框架实现了一种简化的生命周期评估（Life Cycle Assessment，LCA）方法，命名为SSAPTI，用于结合多准则决策分析（Multi-Criteria Decision Analysis，MCDA）与LCA方法的协同应用，评估客运交通舱室内饰。该框架采用按序工作流程，将舱室产品数据转化为一系列影响评估结果，其依据为客观的产品材料数据，以及结合专家主观判断的、被评估产品的生命周期特性及其对用户组织的战略重要性。本框架包含以下工作表组： - "c1. 舱室库存（Cabin Inventory）"：用于存储详细的产品数据记录，涵盖各产品组件的材料与重量标识信息。 - "c2. 可持续性评估（Sustainability Assessment）"：作为整合定量评估要素的核心模块，包含舱室材料的可持续性影响、影响类别权重、循环效应等内容。 - "c3. 循环经济（Circular Economy）"：用于建模舱室产品生命周期的循环场景。 - "c4. 定性生命周期评估（Qualitative LCA）"：由于SSAPTI的应用场景往往无法获取客观的生命周期数据，因此该模块支持基于专家判断的舱室产品生命周期活动定性评估。 - "c5. 战略准则（Strategic Criteria）"：采用非技术准则，基于专家判断对各舱室产品的业务重要性进行定性评估，以调整优先级。 - "c6. 结果汇总（Results Aggregation）"：核心汇总模块，将各评估模块的中期结果整合为各产品的单一最终得分，用以反映其可持续优先级水平。 - 一组支撑6个核心工作表的辅助模块： -- "s1. 生命周期影响评估方法选择（LCIA Method Selection）"：汇总相关生命周期影响评估（Life Cycle Impact Assessment，LCIA）方法的特性，为该框架选取适用方法提供决策依据。 -- "s2. 影响类别泛化（IC Generalisation）"：提供对影响类别（Impact Category，IC）组织方式的参考，将各方法使用的多个独立影响类别整合为通用影响类别，以实现不同方法间的可比性。 -- "s3. 重要性权重赋值（Importance Weighting）"：基于多准则决策分析方法，推导各影响类别以及定性LCA阶段的重要性权重。 -- "s4"系列工作表：用于导入选定LCA数据库（SSAPTI采用EcoInvent数据库）与选定LCIA方法的标准化输出结果，每个工作表对应单一方法，并集成基于MCDA的功能，可将原始LCA数据库输出转化为基于材料重量的相对舱室产品影响值。 -- "s5. 方法对比（Method Comparisons）"：针对各影响类别，对所有纳入的LCIA方法进行对比分析，为用户的优先级制定策略提供参考。 -- "s6. 定性评估（Qualitative Evaluation）"：包含用于分析"c4. 定性生命周期评估"与"c5. 战略准则"工作表的功能模块，不面向用户进行修改或调整。 -- "s7. 参考文献（References）"：梳理本框架全程引用的文献列表。 本框架提供的工作表可作为信息来源，也可由用户根据特定项目需求进行修改。仅可在带有黄色背景的蓝色文本单元格中进行修改，这一规则适用于本框架的所有工作表。不包含黄色背景蓝色文本的工作表均不得修改。
