This article puts forward a decision model for solving a supplier selection problem in a food industry by considering multiple objectives that influence the decision-making process. In times of increasing competitiveness, companies strive hard to improve their profitability, and selection of supply sources may help if an appropriate decision is made through a well-structured decisionmaking process. Preference modeling is conducted in a flexible and interactive elicitation manner with the decision-maker (DM), aided by FITradeoff method. Partial information is gathered about the DM’s preferences in such a way that less effort is spent on finding a final solution for the problem.

5. Conclusions

Given the increasing competitiveness of organizations, it is important to give special attention to key decisions that can improve a company’s results, such as how best to select suppliers. In this context, this paper presented a structured multiple criteria approach for tackling the problem of selecting a supplier of packaging material to a food company. Seven criteria were selected to represent the objectives related to this particular problem, and five vendors were evaluated with respect to these criteria. The preference modeling was conducted considering a purchasing manager’s preferences within a compensatory approach, aided by the Flexible and Interactive Tradeoff (FITradeoff) method.

The elicitation process in FITradeoff was conducted with the DM by means of a Decision Support System, in which the DM interactively answers questions, and then potentially optimal alternatives are sought by solving linear programming problems. FITradeoff DSS also provides graphical visualization for the DM at each step in a flexible way, so that the DM can holistically analyze the performance of the potentially optimal alternatives. This method has been supported by studies based on neuroscience [34].
