The evaluation and selection of a turbine blade material involves several x-abilities and attributes. A designer should consider lifecycle issues as well as design and manufacturing strategies simultaneously at conceptual design stage without missing any of the information. In the proposed methodology the comparison is made between different turbine blade materials based on different x-abilities and attributes. The proposed methodology compares the materials using concurrent engineering approach and multi attribute decision making approach (MADM). In the concurrent engineering approach four x-abilities namely quality, manufacturing, environment and cost are considered. To maintain uniformity attributes considered in MADM approach are same as concurrent engineering approach. Both the methodologies show that ST12TE is the best material for turbine blade for the given set of attributes and x-abilities.

AbstractDecision making in material selection plays important role in selecting appropriate material based on design and manufacturing attributes. Proposing a new material is always a challenging task so the researchers used Decision making assistance tools. In the Present paper the application of Multi-Attribute Decision Making (MADM) methods are applied to the piston material selection for optimal design process. Comparative study of subjective and objective criteria weights on selected MADM methods are done. Sensitivity analysis is conducted to prove the consistency in performance score ranking order as the criteria weights for each alternative varies.

Product development process involves conceptual design selection, which is an activity engaging with numerous types of data including technical-customer specifications and current design developments. This paper presents a conceptual design selection which employs a new technique which accommodates Concurrent Engineering (CE) – Multi Criteria Decision Making (MCDM) strategies. This new technique combines Concurrent Network (CE-ANP), Quality Function Deployment (QFD) and Analytical Hierarchy Process (AHP), referred as CoNQA. To illustrate this technique, a case study is presented involving aerospace application which is the selection of wing spar material. The result shows that the proposed new technique proved to be a sound method which considers product performance, product specification, technical specifications and selection of the best alternative in the selection process. This new method should be a useful aid for designers in collaboration with engineers to perform systematic and parallel technique involving early consideration of technical-customer requirements during conceptual design, hence to establish good product design and increase product competitiveness.

One of the three studied variant solutions of forest road conceptual design was selected based on the linear distribution of criteria, as the method of multicriteria optimization. The selection was performed with 25 parameters classified as economic, technical, production and social criteria. The parameters of technical criteria were grouped into design, construction and building parameters. Based on calculated nominal values of parameters by the given criteria, their ranking, comparison, point rating and scoring, the selected most favorable solution was variant 1.

Many highly accurate computer simulation tools have been developed for assembly line design, such as for simulation of assembly processes, but these tools require much input information and are generally utilized only in detailed design stages. This paper proposes a rapid analysis method for manual assembly line design, which can be utilized in the conceptual design stage. This method is based on a layout tool where design engineers can construct assembly line models using 2- and 3-D views. This method provides design evaluation techniques for multiple important criteria such as volume flexibility, visibility, and so on, using the layout data. Spatial evaluation and quantitative efficiency analyses can be simultaneously performed, which enhance collaborative decision-making in the conceptual design stage.

Mathematics Method

Selecting the favorable conceptual design scheme is the first step to make a new product development (NPD) successfully. To guarantee reliability and rationality of decision-making about multiple design schemes in conceptual design stage under the impact of uncertainties and qualitative information, we have employed KJ method to cluster the evaluation factors into 5 clusters such as emotion, ergonomics, aesthetics, core technology, and impact; and fuzzy mathematics method to deal with uncertainties and qualitative information effectively. The weights of evaluation factors were calculated by analytical hierarchy process (AHP). Fuzzy mathematics method is the comprehensive evaluation method and quantitative analysis which based on the “maximum membership degree evaluation”. All design schemes are ranked and selected according to the multiple evaluation score of parts with their weights. Finally, a case study for decision-making is presented to demonstrate the application of the evaluation method.
