As long as partial information is provided, the flexible elicitation procedure performs dominance tests based on a linear programming problem to explore the DM’s preferences as a vector space which is built using the DM’s partial information.

Abstract This paper contributes to the process of eliciting additive model scale constants in
order to support choice problems, thereby reducing the effort a decision maker (DM) needs
to make since partial information with regard to DM preferences can be used. Procedures
related to eliciting weights without a tradeoff interpretation of weights are justified based on
assumptions that DM is not able to specify fixed weight values or if DM is able to do so, this
would not be reliable information. As long as partial information is provided, the flexible
elicitation procedure performs dominance tests based on a linear programming problem
to explore the DM’s preferences as a vector space which is built using the DM’s partial
information. To provide evidence of the satisfactory performance of the flexible elicitation
procedure, an empirical test is presented with results that indicate that this procedure requires
less effort from DMs.

Additive model
1 Introduction
In multicriteria decision problems, the inter-criteria evaluating parameter is usually called
weights. This is one of the fundamental modeling issues widely discussed in the literature.
The additive model is widely used in the literature (Palha et al. 2016;Pergher and de Almeida
2017), and in such kind of models using weights means using scale constant or tradeoffs,
and declaring which committed relationship the decision maker (DM) is willing to establish
between two criteria. In other methods, weights may be about the relative importance among
the criteria.

... Thus, the model asks him for new relations of preference until a unique solution is found, that is, a situation in which the ideal alternative is found. The solution is found when the subset of potentially optimal alternatives has only one element [69]. Therefore, using the FITradeoff method allows for a more transparent and effective decision-making process [69]. ...

Background: Considering the global concern in balancing economic growth with environmental sustainability, the study proposes a model to support multicriteria decision-making. From the systematic literature review and bibliometric analysis, there was an increasing trend in studies on electronic waste due to governments, stakeholders, and the population to better address the management of this waste; Methods: We propose a decision model considering some aspects and phases that help from collecting information to support decision making, based on the FITradeoff ordering method, to support policy decisions for managing Waste from Electrical and Electronic Equipment (WEEE) collection systems.; Results: After applying the proposed model, validated based on the perception of a decision-maker working in a federal public agency, we obtained the final classification with ten positions of alternatives; Conclusions: This outcome can assist in decision making and management of the collection of WEEE. In addition, we made recommendations to manufacturers have more responsibility in the design and traceability of the product to guarantee its recovery after disposal effectively.
... However, through the steps and graphic tools presented by the software, he felt supported during the process of searching for the best result for his problem situation. Another important issue is that, according to De Almeida-Filho et al. (2017), in the traditional Tradeoff method, given n = 4 criteria, 3(n-1) = 9, questions are needed to reach a solution. ...

Reverse logistics is gaining prominence in a global, economic, social, and political context due to the increasing number of disposable products, a higher environmental concern, and the pursuit of competitive advantage. Thus, reverse flow inventory management is necessary for efficient operational control. However, many organisations are not able to identify and manage all their critical success factors (CSF) simultaneously. Thus, this paper proposes an integrative decision model to identify and prioritise CSFs. This model combines Soft and Hard operation research methods. The priority model can aid DMs to think creatively about their values in messy situations and express them in a structured way, requiring less cognitive effort because it uses partial information in its elicitation procedure. A case study in a Brazilian steel company was conducted to demonstrate the applicability of the proposed model. This model was able to generate practical, managerial, environmental, and social results.
... Some methods apply the tradeoff principle, in which the weights show the importance of a criterion compared to another criterion in a compensatory manner (de Almeida-Filho et al., 2017). Keeney and Raiffa (1976) presented the TRADEOFF weighting that consists of a mathematical function, which integrates information on multiple criteria so that the alternatives represent a value function. ...

Goal: This study aims to review and classify the main methods of criteria weights definition. Design / Methodology / Approach: From a systematized search were articles selected and analyzed, covering a timeline between 1949 and 2020. Results: Fifty sex methods were identified and discussed. Most (49) are subjective, eleven are objectives and three are hybrids. Considering the aggregation procedure, 33 are compensatory and 23 are non-compensatory. Most of the methods are for a single decision maker and just eleven are multidecision makers. The main contributions are published on European Journal of Operational Research journal. Limitations of the investigation: This work does not make a thorough technical analysis of the presented methods and it is not a notebook to indicate to researchers which method is the best for each type of situation. Some methods may not have been included. Practical implications: The selection and the definition of criteria weight is a fundamental question in the Multicriteria Decision Aid (MDCA) approach. The MCDA has a wide application on operation and production management. The diversity of published papers on this subject, the comprehension of its characteristics and applicability is a complex task for researchers and professionals who demand these techniques. Originality / Value: This work contributes to identify the state of the art of the models applied to the weight of the criteria, as well as to identify its characteristics and functionality regarding MCDA modeling.
... Considering these aspects, the multi-criteria approach that best fits the context under analysis is the single-criterion synthesis, which aggregates the criteria into a single synthesis criterion, such as the value or utility of the alternatives (Roy, 1996). Finally, the FITradeoff method Almeida Filho et al., 2017) was considered suitable for the present analysis for a number of reasons: ...

Paper aims: This paper proposes a multicriteria decision approach for supplier selection using a multicriteria method based on Flexible and Interactive Tradeoff (FITradeoff) elicitation process, within the ranking problematic perspective. Originality: This paper develops a framework integrating the results of VFT (Value-Focused Thinking) method with the Triple Bottom Line (TBL) dimension and the veto concept to improve the decision process within a multicriteria perspective. Research method: This study provides a case study in a textile company in Campina Grande, northeast Brazil using data mainly from semi-structured interviews. It also employs quantitative techniques based on problem structuring methods and multicriteria decision making. Main findings: The VFT helped in identifying criteria that are not yet explored by the company, and in structuring the decision problem of how incorporate and balance the TBL dimensions. The recommendation obtained by using the proposed multicriteria decision framework is different from the group of suppliers currently used by the company. Implications for theory and practice: Clarify and identify different objectives and to specify the consequences of a decision problem, allowing the Decision Maker (DM) to obtain and prioritize an economic and sustainable solution for a given number of suppliers to be selected, saving his time and effort.
Chapter
With the advance coming from studies in the area of decision making, different models have emerged to assist in the interpretation of multicriteria decision problems. One of the most recent improvements in the MCDM/A mathematical models deals with the use of partial information about the preferences of the decision makers at the elicitation process. The FITradeoff method is a MAVT (Multi-attribute Value Theory) method that requires only strict preferences and uses partial information in judgments, reducing the amount of information required. Therefore, this study aims to improve the intra-criteria evaluation step of the FITradeoff method, by proposing a new approach for elicitation of marginal value functions based on partial information. The proposed approach is based on the traditional bisection method, but requires preference statements only. The results obtain show that the approach using the bisection method associated with the use of partial information appears to have a good performance, enabling the improvement of the process in terms of reducing the effort and time required.

The linear model practiced in developing countries as Brazil to solid waste management can no longer absorb the amount of waste generated by the cities’ economic activities, and it hinders the self-recovery ability of the environment leading to environmental problems. Consequently, it is necessary a transition to a circular economy model so that environmental problems may be avoided. Brazilian authorities have already been mobilized to seek ways to transitioning, and one way is centered on reverse logistics and shared responsibility for solid waste management laid down in Law No. 12,305/2010. However, this transition does not occur smoothly due to solid waste management in Brazil involves different segments of society, which implies different responsibilities for each segment, as well as a good interaction between them, but there is not an adequate approach to define the responsibilities. Therefore, this study seeks to develop a collaborative approach capable of defining responsibilities towards solid waste management. The proposed approach embedded three methods: Value Focused Thinking, Flexible and Interactive Tradeoff, and Shapley value. The approach was applied to a craft brewery located in a northeastern Brazilian city. The findings show that segments were able to define sustainable responsibilities for the tactical performance of solid waste management in transitioning to a circular economy.

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.

This paper presents a new version of the TOPSIS method for sorting problems. The proposed method, called Preference Disaggregation on Technique for Order of Preference by Similarity to Ideal Solution - Sort (PDTOPSIS-Sort), is based on nonlinear programming for inferring parameters and uses expert's holistic evaluations. The existing TOPSIS-Sort method demands a significant number of parameters from the expert, including the definition of boundary profiles and weights. The proposed method contributes to the literature by relieving the demand for cognitive effort observed in prior methods. Instead of providing boundary profiles for the limit between every two consecutive classes, the expert provides decision examples. In addition, the specification of weights is not required. A numerical validation of PDTOPSIS-Sort was undertaken based on results previously obtained from the literature for TOPSIS-Sort, which has been presented in detail as supplementary material. In addition, the first analysis of Brazilian corporate bonds supported by an MCDM/A model is presented. To do so, data were collected from the financial statements published by the issuers of these bonds. In total, the method proposed classified 50 debentures and the results were consistent with the preferences of the decision-maker, an investment-banking expert.

Water supply systems in urban areas may become deficient due to increasing demand, which accompanies population growth but is further jeopardized by equipment aging and problems related to maintenance management. Moreover, operating the system involves a large number of issues that a decision-maker must address simultaneously. Therefore, the use of tools to aid the decision process is quite relevant in providing a better understanding of the problem and to generate a recommendation that better meets the wishes of the decision-maker. This study presents a model based on the value-focused thinking approach, requiring only partial information in the multi-attribute analysis by using linear value functions and FITradeoff, entailing less effort to achieve the ideal alternative. The model was applied to the operations manager of the water supply company in the central region of Olinda in the state of Pernambuco, Brazil. Consequently, the model yielded a deep analysis of the manager’s reasoning, which was transcribed through the objective’s hierarchy, and reached a solution to the problems of the local water supply system.

Processing information is a key ingredient for decision making. In most decision-making cases, information is distributed across various sources that may differ in reliability and accuracy. Various sources and kinds of uncertainty are encountered in the same decision situation. “Information imperfections” is a general term that encompasses all kinds of “deficiencies” (such as uncertainty, imprecision, ambiguity, incompleteness) that may affect the quality of information at hand. In discrete multicriteria decision making, where several alternatives are assessed according to heterogeneous and conflicting criteria, information used to assess such alternatives can also be imperfect. It is rather natural, in such a context, to seek additional information to reduce these imperfections. This paper aims at extending the Bayesian model for assessing the value of additional information to multicriteria decision analysis in a context of imperfect information. A unified procedure for processing additional information has been proposed in a previous work. It leads to prior and posterior global preference relational systems. It will be extended here to include pre-posterior analysis where concepts such as the expected value of perfect information and the expected value of imperfect information are adapted to multicriteria decision making choice problems.

This paper arose from the perceived need to make a contribution towards assessing a strategic information system by using a new method for eliciting the weights of criteria. This is considered one of the most complex and important stages in multicriteria models. Multicriteria models have been proposed to support decisions in the context of information systems given that problems in this field deal with many conflicting criteria. The new procedure for eliciting the weights of the criteria has the advantage of requiring less effort from the decision-maker and, thus, the risk of inconsistent answers is minimized. Therefore, a model based on this new procedure is proposed and applied using data from a glass packaging factory that needs to select a single information system from a set of systems previously identified as relevant. The results obtained are consistent both with the performance of alternatives and with the additive model used to evaluate the alternatives.

The subcontractor’s selection problem is currently treated as a supply chain problem with a prequalification procedure to balance the main objectives of the client: cost, quality, and time. Unfortunately, most of the selection processes are analysed under the same methodology without considering that variations in project, type of activity, and other attributes should affect the chosen method. To provide a novel form of treating subcontractor’s selection, we proposed an additive sorting method to categorize activities to be outsourced in civil construction based on ROR-UTADIS method, which is a modification of the UTADIS method that includes new forms of supplying preference information. It was applied in the construction of a brewery in Brazil. It was perceived that the method is applicable and intuitive for decision makers, even though there are quite a few points to be taken, analysed to avoid misclassification.

Production and inventory-related decisions, which significantly influence each other and sometimes involve multiple attributes, trade-off assessment and uncertainties, serve a key role in the performance of make-to-stock (mts) manufacturing systems that are controlled by a constant work in process (conwip) order release policy. To benefit from established production planning methods, a crucial task in this context is to define suitable production parameter settings for a given planning horizon. To address this problem, we present a multi-attribute decision model to determine appropriate settings for the planning parameters, namely, cycle time, throughput rate, holding cost and stockout cost. The proposed model uses discrete event simulation to evaluate the performance of a conwip/mts manufacturing system in relation to the work in process and finished goods inventory. Analysis of variance (ANOVA) and a Kruskal-Wallis test are conducted to verify the significant effect on the analyzed parameters. The compromise solution that is recommended for the conwip/mts problem is obtained by considering a multi-attribute expected utility function that is representative of a decision maker’s preferences and risk attitude regarding the probability distribution of the simulation outputs. In contrast with preview studies on planning parameter setting, the result compensates the low performance of one of the attributes as a result of the high performance of another attribute, based on the axiomatic structure of MAUT. Based on the real data of a multi-product assembly line, a numerical application is employed to visualize the steps of this decision model and to demonstrate its usefulness in practical issues.

Using pipelines to transport fuels is considered safe and financially viable. Multicriteria decision models are used as they lead to managing risk better and to more effective decision-making when assessing risk to hydrogen pipelines. Nevertheless, there is recurring concern about the possibility of accidents occurring due to failures in the storage structure and/or when transporting hydrogen. Given the uncertainties inherent when using these models, Monte Carlo simulations are conducted and the results are analysed based on Kendalls τ correlation coefficient. This coefficient was fundamental for understanding the behaviour of different rankings obtained by simulations, since information was generated on ranges of uncertainty and on recommendations to decision-makers. The article suggests steps on how best to conduct a sensitivity analysis and to ensure that results are robust, based on a model that uses graphs within Information visualization that support the decision-maker when ranking pipeline sections and to mitigate risks.

This paper presents two approximate methods for multiattribute utility measurement, SMARTS and SMARTER, each based on an elicitation procedure for weights. Both correct an error in SMART, originally proposed by Edwards in 1977, and in addition SMARTER is simpler to use. SMARTS uses linear approximations to single-dimension utility functions, an additive aggregation model, and swing weights. The paper proposes tests for the usability of these approximations. SMARTER, based on a formally justifiable weighting procedure developed by Barron and Barrett, uses the same procedures as SMARTS except that it omits the second of two elicitation steps in swing weights, substituting calculations based on ranks. It can be shown to perform about 98% as well as SMARTS does, without requiring any difficult judgments from elicitees. (C) 1994 Academic Press, Inc.

This work concerned with multi-attribute decision making problems with imprecise weights. A new dominance measuring-based method is proposed and compared with some existing methods. A series of simulations are conceived to study the performance of these methods in selecting the best alternative with different forms of imprecise weights. Results show that the new method performs better than the classical decision rules and other dominance measuring methods in terms of identifying the best alternative with ordinal weights. As to interval information, the new method also has a better performance.
