“…When using THOR, the simultaneous input of data into the process from multiple decision makers is also permitted, enabling these to express their judgment values in scales of ratios, intervals or ordinals, in addition to the execution of the decision making process without necessarily attributing weights to the criteria (Gomes, 2005;Cardoso et al, 2009). …”

This article approaches the problem of selecting the non-dominated alternative for the destination of the natural gas reserves in the Mexilhão field in the Santos Basin, Brazil. Major aims of the case study reported here were to create a mechanism for assisting in the process of analyzing and selecting the best options for the destination of natural gas, and to enable the decision agent to choose the investment options best aligned to the expectations and objectives observed in the company strategies. The decision analysis employed in the study made use of the TODIM method and the THOR multicriteria decision support system. The application of both demonstrated that a decision analytic framework can be extremely useful when recommending options for upstream projects, owing to the fact that it can clearly identify the most important alternatives in the face of the scenarios tested and in relation to the criteria expressed. Keywords: energy resources in Brazil; multicriteria decisions; prospect theory. ResumoEste artigo tem como propósito selecionar a melhor alternativa para usar o gás natural proveniente das reservas do campo de Mexilhão existente na Bacia de Santos. O principal objetivo do estudo é a criação de mecanismos que permitam a análise e posteriormente possibilitem a escolha da alternativa não-dominada de destinação do gás natural; e dar apoio ao decisor na seleção da melhor alternativa de investimento considerando as expectativas e os objetivos estratégicos da companhia. O estudo é feito fazendo uma comparação das sugestões a partir dois sistemas, um implementando o Método THOR e outro o método TODIM. A aplicação simultânea dos métodos permite auxiliar o decisor neste processo em função dos cenários e dos conjuntos de critérios identificados.Palavras-chave: fontes de energia no Brasil; decisão multicritério; teoria dos prospectos.

“…Although the inherent subjectivity of value judgements for the weightings is a basic assumption of MCDA techniques [23], the influence of the specific personal management context of the participants has not been tested. The research question was therefore raised: Do the professional exposures and experiences of individuals, with respect to the size of the corporation where they are employed and their years of employment, influence their opinions of the relative importance of the sustainable development dimensions?…”

Industries are increasingly under pressure to incorporate the objectives of sustainable development into company policies and decision-making processes. This study introduces a framework of sustainability assessment criteria that are relevant to projects and developments in industry. The study attempts to establish whether the professional exposure and experience of decision-makers at different management levels influence the individual's perceptions of the relative importance of the three main dimensions of the framework. The study finds that exposure and experience do not influence the weighting values. The study further highlights the importance of distinguishing between internal decision-making within industry and external decision-making where assessments are used for public reporting. That is, the context within which the three dimensions are weighted greatly determines individual and societal perceptions. OPSOMMINGIndustrieë is toenemend onder druk om die doelwitte van volhoubare ontwikkeling in maatskappybeleid en besluitnemingsprosesse te inkorporeer. 'n Raamwerk van volhoubare assesseringskriteria word voorgestel wat relevant is vir projekte en ontwikkelinge in die industrie. Hierdie studie beoog om te bepaal of professionele blootstelling en ondervinding van besluitnemers 'n invloed het op individuele persepsies van die relatiewe belangrikheid van die drie hooffasette van die raamwerk. Die studie vind dat ondervinding en blootstelling geen invloed uitoefen op die relatiewe gewigte nie. Die studie lig verder die belangrikheid uit om te onderskei tussen interne besluitneming binne maatskappye, en eksterne besluitneming waar assessering gebruik word vir publieke rapportering. Met ander woorde, die konteks waarin gewigte op die drie dimensies geplaas word, bepaal grootliks individuele-en gemeenskapspersepsies.

“…A comparison of TODIM against THOR (Gomes, 2005) in real state market evaluation has pointed out that both approaches have been capable in practice to assist professionals in the real estate market to evaluate the alternatives more clearly in relation to the criteria defined by the experts. The analysis of the alternatives using both THOR and TODIM led to ranks orders for extreme values.…”

ABSTRACT. Evaluation of real estate properties is an important factor in any economy. The appraisal process is rather subjective, based on the appraiser's experience and intuition. Attempts are being made to help appraisers produce more stable and reliable results. In the paper the authors present an integrated approach to the problem based on the multicriteria decision making framework. The process is carried out through three phases using the multicriteria method TODIM. An "adjusted value" iterative procedure for market value estimation is proposed. The final property price ensures that the overall quality of the alternative obtained through the TODIM method is not farther from the comparable properties on the market than the stated threshold. The process is illustrated through an application in the city of Volta Redonda (Brazil). The results are compared with the "proportional approach". The "adjusted value" approach showed significant improvement compared to the "proportional" adjustment of market values.

Using MCDA methods THOR in an application for outranking the ballast water management options

Abstract: The Multicriteria Analysis Methodology has been developed in order to support and guide decisionmakers in the evaluation and selection of alternatives/solutions. In this case, it is used to compare alternatives for the management ballast water (BW) exchange systems and treatment methods.
