Translating shipowner requirements into multipurpose shipyard design priorities using PAPRIKA–QFD

Multipurpose shipyards integrate shipbuilding, ship repair, and ship recycling within shared physical and organisational systems, yet customer-driven approaches for translating shipowner requirements into technical priorities across these operational domains remain limited. This study applies and adapts a sequential Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA)–Quality Function Deployment/House of Quality (QFD/HoQ) procedure to an anonymised Indonesian multipurpose shipyard. PAPRIKA was used to derive trade-off-based weights for 30 shipowner requirements from 101 retained first-tier respondent profiles, and these weights were used directly as HoQ customer-importance weights. Twelve facility-oriented technical responses were assessed independently by three experts representing shipbuilding, ship repair, and ship recycling, enabling both integrated and domain-specific technical-importance analyses. Schedule reliability (20.42%), technical capability and quality assurance (19.34%), compliance and safety assurance (18.65%), and economic competitiveness (18.19%) received the highest shipowner-side criterion weights. In the integrated analysis, workforce development and support (14.27%), regulatory and engineering support (12.69%), and inspection and quality, health, safety and environment (QHSE) infrastructure (12.00%) were the three highest-ranked technical responses. However, domain-specific priorities differed substantially: workshop and controlled work-area capacity ranked first in shipbuilding, docking and surface-treatment capacities were prominent in ship repair, and environmental control and waste-management infrastructure ranked first in ship recycling. Robustness analyses retained the same three highest-ranked integrated responses under expert-exclusion and alternative aggregation scenarios. The results show that an integrated ranking can identify cross-cutting priorities, but should complement rather than replace domain-specific technical priorities. This study contributes a transparent application of PAPRIKA-derived preference weighting within a lifecycle-spanning multipurpose-shipyard HoQ, while providing relative technical priorities rather than quantitative facility-design outputs such as capacity sizing, layout, or investment sequencing.
