Selection of a most appropriate material is a very important task in design process of every product. There is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations and in making right decisions. This paper proposes a novel multiple attribute decision making (MADM) method for solving the material selection problem. The method considers the objective weights of importance of the attributes as well as the subjective preferences of the decision maker to decide the integrated weights of importance of the attributes. Furthermore, the method uses fuzzy logic to convert the qualitative attributes into the quantitative attributes. Two examples are presented to illustrate the potential of the proposed method.

DFMEA is a significantly efficient tool to systematically evaluate risk in early stage of product design and development but some of knowledge and information are uncertain and imprecise. This research focuses on fuzzy logic approach to diminish weaknesses and applies to launch tube’s DFMEA. The methodology started from determine membership function of severity, occurrence, and detection and provide fuzzy rule base to arranged category of risk. Afterwards, center average index was selected as defuzzifier for risk value representation. Consequently, the prioritization based on risk value was done and chosen the first five risk value of potential failure modes to analyze causes then recommended appropriate actions. After application of fuzzy logic approach, the most vital potential failure mode is damaged launch tube due to detention force which is rated as first and second priority depending on potential cause or mechanism. The third priority is launch tube distortion. The mechanical load calculation and proper material selection are the recommended actions for overcoming those potential failure modes.

The selection of materials for a product in mechanical design holds a great importance as the selection of a specific material can impact the success or failure of the product. There are lot of methods and approaches that are available for material selection process, but majority of them work well with only material properties dealing in quantitatively measured properties. With so much amount of material being developed and researched each and every day, the selection of an optimum material has become a fuzzy characteristic. In this chapter, a simplified fuzzy logic is used as a simple, easy and effective method for choosing an optimum material in mechanical design problems. An illustration is carried out when the fuzzy logic is applied to the selection of material for aircraft wing's spar and how an optimum material is achieved.

Fuzzy logic is a moderately new method for tackling building control issues. This method is regularly used to execute frameworks beginning from simple, small or even inserted up to monster. Fuzzy set hypothesis has been usual model frameworks that are challenging to diagram precisely. As a system, fuzzy set hypothesis joins imprecision and subjectivity into the model definition and arrangement prepare. Probabilistic techniques are being utilized progressively in development building. However, when a parameter is communicated in phonetic as opposed to numerical terms, traditional likelihood hypothesis neglects to consolidate the data. The etymological factors can be converted into scientific measures utilizing fuzzy set and framework hypothesis. A development administration issue i.e., estimation of term of an action, is unrevealed utilizing this hypothesis. The proposed procedure is not touchy to little varieties in the participation values. This is an extremely alluring property. In any case, the strategy is delicate to the decision of the fuzzy relations. The instability in the fuzzy relations can be demonstrated alongside different wellsprings of vulnerability. The mean and difference of the parameters required in the issue under thought are evaluated here utilizing another technique. The strategy boosts the result of the whole of the enrolment relationship for a specific recurrence of event and the comparing recurrence of event. One of the primary favorable circumstances of the proposed method is that it can be effortlessly actualized in existing PC programs for venture planning. In Green building planning viewpoints, material choice assumes a significant part in accomplishing the building guidelines; it is possible that it might be of green or non-green materials. Keeping in mind the end goal to accomplish perspective consummately, essential Fuzzy logic approach is to be actualized in order to choose the best option among different accessible materials. This should be possible by dispensing the essential enrolment values based upon the past encounters and positioning them in a request in view of our development necessities all the while. By utilizing this approach, we can likely choose the best material in view of both subjective and quantitative perspective

Abstract.A new method was developed for continuous isotopic estimation of human whole body CO2 rate of appearance (Ra) during non-steady state exercise. The technique consisted of a breath-by-breath measurement of 13CO2 enrichment (E) and a real-time fuzzy logic feedback system which controlled NaH13CO3 infusion rate to achieve an isotopic steady state. Ra was estimated from the isotope infusion rate and body 13CO2 enrichment which was equal to E at the isotopic steady state. During a non-steady state incremental cycle exercise (5 w/min or 10 w/min), NaH13CO3 infusion rate was successfully increased by the action of feedback controller so as to keep E constant.
