A publicação do novo marco legal do saneamento básico no Brasil – LEI Nº 14.026, de 15 de julho de 2020 definiu novos prazos iminentes para encerramento dos 3326 “lixões” e aterros controlados no território nacional. A importância do fim das atividades ou s adequação das áreas de disposição irregular de RSU é primordial para a eliminação/redução da contaminação dos compartimentos ambientais. Com as dificuldades financeiras e índices de avaliação de qualidade de áreas de disposição subjetivos – IQR (CETESB) e IQDR (INEA) pouco foi feito pelos gestores municipais nessas áreas. A fim de superar a subjetividade na utilização desses índices e direcionar ações efetivas, este trabalho propõe um novo Índice de Qualidade de Áreas de Disposição Irregular de RSU (IQUADI), baseada na Análise Hierárquica de Processo (AHP), definindo-se intervalos específicos para os critérios selecionados a partir de levantamento bibliográfico e documental. Os resultados finais mostram aos responsáveis pelos passivos ambientais se as atividades na área serão encerradas ou continuarão e quais medidas a serem adotadas. Verificaram-se divergências legais nos limites usualmente utilizados e novos limites foram propostos para os critérios componentes do IQUADI. A aplicação comparativa (estudo de caso) do IQUADI e do IQR no aterro controlado de Volta Redonda permitiu concluir que o IQR apresenta 58% de subjetividade para a seleção dos pesos de cada critério, ao contrário do IQUADI que apresentou valores específicos para cada intervalo selecionado integrante dos critérios. Subjectivity reduction in the MSW disposal areas classification through a new index applying Hierarchical Process Analysis: Quality Index of Irregular MSW Disposal Areas – IQUADIA B S T R A C TThe new legal framework publication for basic sanitation in Brazil in July 2020 defined new imminent deadlines for the closure of the 3326 “dumps” and controlled landfills in the national territory. The importance of the end of activities or the adequacy of MSW irregular disposal areas is essential for the elimination / reduction of contamination of environmental compartments. With the financial difficulties and the subjectivity of the quality assessment indexes of disposal areas - IQR (CETESB) and IQDR (INEA), little has been accomplished by municipal managers in these areas. In order to overcome the subjectivity in the use of these indices and direct effective actions, this work proposes a new Quality Index for MSW Irregular Disposal Areas (IQUADI), based on the Analytic Hierarchy Process (AHP), defining specific intervals for the selected criteria from a bibliographic and documentary survey. The final results show those responsible for environmental liabilities whether activities in the area will be closed or will continue and what measures must be performed. Legal differences have been identified in the limits usually used and new values were proposed for the criteria that compose IQUADI. The comparative application (case study) of  IQUADI and IQR in the controlled landfill of Volta Redonda allowed us to conclude that the IQR presents 58% subjectivity for the selection of the weights of each criterion, in contrast to the IQUADI which presented specific values for each interval selected integral to the criterion.Keywords: municipal solid waste, closure, quality index, analytical hierarchy process.

From January 2020, the International Maritime Organization has regulated ship emissions to reduce sulfur content. As an alternative to this, LNG bunkering was proposed, and infrastructure and ships were deployed. Therefore, we used analytic hierarchy process AHP techniques to determine optimal methods of LNG bunkering for shipyard safety. First, we conducted a literature survey on the concept and type of LNG bunkering, global LNG bunkering trends, and features of Japan and South Korea cases and compared them. Thereafter, an expert survey was conducted, and survey data was analyzed using AHP techniques. Finally, we derived optimal methods applicable to shipyard industry. The analytical results revealed that the derived priority of the optimal LNG bunkering method of shipyard was in the order of the STS method, TTS method, and the PTS method. The result of this study can serve as a theoretical basis to make LNG bunkering safer and more economical in shipyards to prepare for the expansion of demand of LNG-fueled ships and LNG. However, this study inevitably has limitations of ranking reversals paradox as it was conducted by experts, assuming no weights to STS, TTS, or PTS.

Hierarchy Process

Quality function deployment (QFD) is a methodology that extracts client demands (CDs) and inducting them in the final service/product. Once CDs are extracted from client the traditional QFD approach uses absolute importance to identify the degree of importance for each CD. Direct evaluation of CDs based on absolute weighting without tradeoffs is easy to perform, but may lead to serious deviations from reality. An alternative to avoid this problem is to adopt the analytic hierarchy process (AHP) approach. In this paper, an integrated model combining AHP and QFD has been delineated as a quality achievement tool in healthcare. A case study is performed on the healthcare services provided by government general hospital, Indore District, Madhya Pradesh, India and data has been analyzed to benchmark the proposed framework by computing the degree of relative importance for CDs through AHP and incorporating them in subsequent deployment matrices.

Decision Support Method

It is possible to produce different database designs based on the same set of requirements to a database. In this paper, we present a decision support method for comparing different database designs and for selecting one of them as the best design. Each data model is an abstract language that can be used to create many different databases. The proposed method is flexible in the sense that it can be used in case of different data models, criteria, and designs. The method is based on the Analytic Hierarchy Process and uses pairwise comparisons. We also present a case study about comparing four designs of SQL databases in case of PostgreSQL? database management system. The results depend on the context where the designs will be used. Hence, we evaluate the designs in case of two different contexts - management of measurements data and an online transaction processing system.

Hierarchy Process

The paper investigates how different hierarchy structuring in analytic hierarchy process (AHP) may affect the final results in the decision-making process. This problem is analyzed in a case study of the Rila monastery forest stands in Bulgaria. There were three similar and mutually overlapped hierarchies defined. A decision maker evaluated all of them and after analyzing final results and consistency performance, he selected and revised the most appropriate hierarchy structure. Consistency check assisted in detecting the judgments which have strongly violated evaluation procedure. These mistakes are interpreted as a consequence of a large number of required pair-wise comparisons. The paper emphases the importance of properly defining hierarchy structure and recommends using consistency analysis as a guide and not as a directive for the revision of judgments.
