20.500.12556/RUL-179991 A non-compensatory framework integrating LCA and QFD for robust manufacturing sustainability decisions under uncertainty: an OCC paper machine case study Manufacturing decarbonization and sustainability improvement require decision-support methods that can prioritise actions across multiple, often conflicting dimensions, including product quality, process stability, resource efficiency, and environmental performance. In industrial practice, such decisions are further complicated by stochastic variability and the presence of dominant drivers, which limit the usefulness of conventional linear, weighted- sum scoring approaches. This paper proposes a non-compensatory decision framework with explicit stochastic uncertainty propagation that integrates quality function deployment (QFD) with life cycle assessment (LCA) to support robust, value-driven prioritisation of manufacturing improvement actions under uncertainty. The approach combines QFD-style influence factor modelling with LCA-based environmental indicators and employs a non- linear, non-compensatory aggregation scheme to reduce sensitivity to arbitrary weighting and to better capture dominant and tail-risk effects. Uncertainty is propagated using Monte Carlo simulation, and the stability of prioritisation outcomes is analysed using sensitivity measures. The framework is demonstrated on an industrial old corrugated container (OCC) paper machine line using operational data from plant information systems, including quality, process control, laboratory, and maintenance databases. Results show that the proposed integration yields more stable and interpretable prioritisation of improvement actions than conventional compensatory scoring methods, particularly under variable operating conditions. The proposed approach enables practical, data-driven sustainability decision-making in complex manufacturing processes under variable operating conditions and alternative process configurations. non-compensatory aggregation decision-support framework uncertainty analysis nekompenzacijska agregacija struktura za podporo odločanju analiza negotovosti true false true Angleški jezik Slovenski jezik Članek v reviji 2026-02-27 11:40:38 2026-02-27 11:40:45 2026-02-28 04:43:37 0000-00-00 00:00:00 2026 0 0 20 str. issue 4, art. no. 649 Vol. 14 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.94:502.131.1 2227-9717 10.3390/pr14040649 269790467 RAZ_Rihar_Lidija_2026.pdf RAZ_Rihar_Lidija_2026.pdf 1 E769F1DC17FC7363BA155BEA6F8753DC c7e9ae623dc4e47ade41bd1e57ee5a8ba7e39e2510d2a3e9072a3cc10160e166 638a3478-13c9-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228981 https://www.mdpi.com/2227-9717/14/4/649 1 70a5a5f8-13c8-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228979 Fakulteta za strojništvo 0 0 0
