Enriching descriptive information in ranking and sorting problems with visualizations techniques

Abstract

International audiencePurpose - Most of the proposed decision aid methods provide the user only with a prescriptive approach (quantitative analysis) without any descriptive approach (qualitative analysis). It is therefore not possible to justify and recommend ways of improvement. The purpose of this paper is to introduce visualization techniques to complement prescriptive approaches. Design/methodology/approach - Visual techniques have been developed for the FlowSort sorting method, namely the FS-GAIA and stacked bar diagrams. Findings - It is found that with visual techniques, fine details can be captured, e.g. detection of incomparability (with FS-GAIA) and the composition of a score (with stacked bar diagrams). Research limitations/implications - In the future, it is expected that other multi-criteria decision methods will be complemented by prescriptive approaches. Practical implications - A real case study is introduced in order to illustrate the practicality of the visual techniques. In this paper, the innovation performances of small and medium enterprises from the French Lorraine region are assessed. Social implications - It is expected that the quality of the decisions taken are improved because of being better informed. Originality/value - The paper, using a real case study, provides important new tools to enhance decision quality

Marketing Approach of Brazilian Wind Energy Sector

“…These practices are concrete actions executed by the enterprises to define their strategy, to guide and to impel the innovation processes and to make evolve the organization or its methods of work. After further research work, (Assiélou 2008;Morel and Boly 2008;Rejeb et al 2008;Sepulveda et al 2010;Nemery et al 2012;Boly et al 2013). A general referential framework of internal innovative practices for an ideal company has been proposed.…”

“…Note that the list can be enhanced or modified as new innovation management practices emerge. Multicriteria computation of the index follows a flow-sort algorithm as described in Nemery (2012), which uses the firm's answers of the form, and the set of weights described in Table 1. Once the IIP index obtained for the set of evalu- Regarding the geographical context, there is no significant differences between both countries, as the average IIP for the French companies is of 0.266 and for the Argentinian companies is of 0.262.…”

Visual management of performance with PROMETHEE productivity analysis

“…Moreover, MCDM can also help to analyse the performance of actions (also called alternatives). For example, da Rocha et al (2016) evaluated the operational performance of Brazilian airport terminals using Borda-AHP, Longaray et al (2015) used MACBETH to evaluate Brazilian university hospitals, Nemery et al (2012) evaluated the innovation capacity of small and medium enterprises (SMEs), Ishizaka and Pereira (2016) developed a hybrid ANP-PROMETHEE method for evaluating employee performance and Galariotis et al (2016) used MAUT to evaluate French local governments.…”

“…It is important to have an understanding of the current situation, but the required analytical process can be complicated. Possible corrective strategies also need to be identified and discussed and it has been proposed that visual analytical tools offer a way of presenting, justifying and explaining them effectively and transparently (Nemery et al 2012;Ishizaka and Pereira 2016). Visual representation permits users to take in a large amount of information simultaneously as it maximises human capacity to perceive, understand and reason about complex data and situations.…”

Which energy mix for the UK (United Kingdom)? An evolutive descriptive mapping with the integrated GAIA (graphical analysis for interactive aid)–AHP (analytic hierarchy process) visualization tool

“…The GAIA method was initially proposed to complement PROMETHEE which is widely used in strategic decision making [3]. GAIA has recently been combined with Geographical Information Systems [4] and FlowSort [5].…”
