The Flexible and Interactive Tradeoff (FITradeoff) method is a multicriteria decision making/aiding (MCDM/A) method that uses partial information about the decision maker's (DM's) preferences in order to build a recommendation. This method preserves the strong axiomatic structure of the traditional tradeoff procedure, with an interactive and flexible process that demands less cognitive effort from the DM. Although FITradeoff has already been applied for aiding several practical decision situations, there is no previous study that tests the performance of this method with respect to expected theoretical benefits such as time and effort reduction. In this context, this paper presents the results of a simulation experiment that aims to analyze the behavior of FITradeoff in a wide range of scenarios. Computational constraints were identified in the simulation process, such as the number of simulations for each iteration. Despite the memory limitation of the software used, the number of total simulations performed was greater than what is commonly found in literature. We investigate how the performance of FITradeoff can be affected by changes in number of criteria, number of alternatives and weight pattern, and therefore it is possible to have a deeper understanding of the method and its main features. Therefore, this work focuses on studying, through simulations, the behavior of the multicriteria method FITradeoff, developed by De Almeida et al. (2016), filling a lack in the literature by analyzing said method in a wide array of scenarios by a simulation process in order to bring a better understanding of the method, as well as to validate it in a simulation study.
For the transition towards a circular economy (CE), organisations have to be prepared to adapt to major changes. Thus, the concept and implementation of change management (CM) will be essential to an organisation’s success during this transformative period. Studies have shown that organisational CE barriers were more significant than individual CE barriers. To overcome such obstacles, the most appropriate set of managerial practices should be carefully considered. These barriers also have the potential to influence the agricultural sector, which seeks to adopt more sustainable ways of production. The goal of this paper is to propose a solution framework based on CM strategies to overcome organisational challenges posed by a CE, especially for agribusinesses. To accomplish this objectively, a systematic literature review and a content analysis were conducted. The common errors in CM within the implementation process and the main CE barriers were identified and classified. An in-depth analysis of the issue’s roots led to a solid understanding of how to tackle such CM problems. This paper presents an overview of organisational CE barriers verified in the agricultural context, the common errors in CM, and the correlation between these findings. The two areas were then combined in a matrix that shows the connection between common errors in CM errors and CE barriers. Based on this result, a solution framework called 3CE2CE was developed that provides a step-by-step guide on how organisations can successfully undergo transformation processes towards a CE with the principles of CM.
