Abstract

Paper aims: This paper aims to support decision-makers of the public slaughterhouse of Sumé in the preliminary selection of machinery for animal slaughter operations based on quantitative technical and economic criteria derived from equipment specifications.

Originality: The originality of this study lies in the integrated application of the Modified Preference Selection Index (MPSI) and the Weighted Aggregated Sum Product Assessment (WASPAS) methods to a real-world public slaughterhouse context. The study contributes by using MPSI to generate data-driven criterion weights and WASPAS to rank machinery alternatives in a transparent selection framework.

Research method: The research adopts a multicriteria decision-making (MCDM) approach, employing the MPSI method to determine criterion weights and the WASPAS method to rank machinery alternatives using quantitative technical and economic data obtained from manufacturers’ manuals, catalogues, and technical sheets, with contextual validation provided by a slaughterhouse inspector.

Main findings: The integrated MPSI-WASPAS model identified a favourable set of machinery alternatives with superior overall performance across the evaluated technical and economic criteria.

Implications for theory and practice: The study reinforces the applicability of hybrid MCDM methods in public infrastructure contexts and provides a transparent decision-support framework for preliminary equipment screening in public slaughterhouse projects.
