Prioritizing Improvement Actions in a Fish Distribution Company: Integrating Elicitation by Decomposition and Holistic Evaluation with FITradeoff Method.

In this paper, a prioritization problem of strategic improvement actions of a Fresh Fish Distribution Company (FFDC) is approached. Improvement actions to be prioritized are defined based on critical success factors derived from the SWOT analysis of the company, conducted by multiple stakeholders of the organization. Four criteria were defined to evaluate these actions, and then the FITradeoff (Flexible and Interactive Tradeoff) multicriteria method is applied to aid the decision process and preferences assessment. This method works based on partial information of the DMs to elicit criteria scaling constants in additive models, considering structured elicitation process based on tradeoffs. Throughout an interactive Decision Support System (DSS), this work illustrates how the decision process can be carried out with FITradeoff based on an integration of two paradigms in preference modeling: elicitation by decomposition and holistic evaluations.
