Value-Focused Thinking (VFT) provides a systematic approach to structure complex decisions for subsequent analysis. It is powerful complement decision analysis and its application has been growing in recent years. This paper discusses the of VFT Brazil three problems different contexts: water management, information system/information technology (IS/IT) strategic planning, disposal plaster waste. article describes how was used these identify alternatives stall them, which led developing...

This paper puts forward a proposal for multicriteria decision model prioritizing technologies that are critical power generation in the energy sector. It deals with context of imprecise information regarding importance criteria; then an integration surrogate weights PROMETHEE method is undertaken order to approach this context. In type strategic problem, how deal always challenge. The use presents significant contribution and it can facilitate assignment ranking which requires decision-maker...

Sound decision-making processes for investments in water supply systems need to be developed. This arises from the problem observed developing countries of a growing demand projects coupled with lack financial resources available invest them.

A structured evaluation of the construction industry's suppliers, considering aspects which make their quality and credibility evident, can be a strategic tool to manage this specific supply chain. This study proposes multi-criteria decision model for suppliers' selection from industry, as well an efficient procedure selected suppliers. The is based on SMARTER (Simple Multi-Attribute Rating Technique Exploiting Ranking) method its main contribution new approach structure process selection,...

The losses in the urban water supply networks have become a growing concern. There are several alternatives for quantification, detection and monitoring of losses. However, general, companies budgetary other constraints that hinder implementation. Therefore, this paper presents model to aid selection subset preventive maintenance actions control while accounting companies' restrictions. combines an additive multi-attribute value analysis by applying SMARTER method evaluate with Integer...
