Recent research has recognised that multicriteria decision making (MCDM) should take account of uncertainty, risk and confidence. This paper takes this research forward by using linguistic variables and triangular fuzzy numbers to model the decision maker’s (DM) risk and confidence attitudes in order to define a more complete MCDM solution. To illustrate the computation process and demonstrate ...

--------------------------------------------------------ABSTRACT----------------------------------------------------------The significance of decision making from the maintenance perspective has long been acknowledged by the manufacturing industry. Appropriate maintenance alternative decision making increases machine reliability and enhances both productivity and product quality. By contrast, p...

In the real-world problems, we are likely confronted with some alternatives that need to be evaluated with respect to multiple conflicting criteria. Multi-criteria decision-making (MCDM) refers to making decisions in such a situation. There are many methods and techniques available for solving MCDM problems. The evaluation based on distance from average solution (EDAS) method is an efficient mu...

The soil is not always suitable or competent to support a direct shallow foundation in construction. In many cases, avoid costly deep foundations, it indicated replace, improve, reinforce such soil. This paper focuses on evaluating the contribution sustainability between different improvement techniques and outcome of their application single-family house as an alternative one built. life-cycle...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

one of the most effective tools for decline cost and time, quality improvement and consequently project performance enhancement especially in construction projects, is value engineering. there are linguistic judgments in many cases of value engineering studies in construction projects such as interior design, mechanical installations design, and etc. therefore multiple attribute decision-making...

Concepts of decision design are introduced via Multiple Criteria Decision Making (MCDM), Knowledge Management (KM) and optimisation. Decision-making conflict is defined as the absence of a prominent tradeoffsfree alternative. Because tradeoffs are properties of alternatives (the measured) and not of criteria (the measures), designing an optimal decision involves designing a tradeoffs-free alter...

  Multiple criteria decision making (MCDM) problem is one of the famous different kinds of decision making problems. In more cases in real situations, determining the exact values for MCDM problems is difficult or impossible. So, the values of alternatives with respect to the criteria or / and the values of criteria weights, are considered as fuzzy values (fuzzy numbers). In such conditions, th...

In today’s highly competitive manufacturing environment, an effective supplier selection process is very important for the success of any business organization. Selection of the best supplier is always a difficult task for the purchasing manager. Suppliers have varied strengths and weaknesses which require careful assessment by the purchasing manager before selecting and ranking them. Any suppl...
