This paper presents a hierarchical fuzzy evaluation approach to product lifecycle sustainability assessment at conceptual design stages. The purpose is to advocate the emerging use of lifecycle engineering methods in support of evaluation and selection of design alternatives for sustainable product development. A fuzzy evaluation model is developed with a hierarchical criteria structure to represent different sustainability considerations in the technical, economic and environmental dimensions. Using the imprecise and uncertain early-stage product information, each design option is assessed by the model with respect to the hierarchical evaluation criteria. Lifecycle engineering methods, such as lifecycle assessment and lifecycle costing analysis, are applied to the generation of the evaluation criteria. This would provide designers with a more complete lifecycle view about the product’s sustainability potentials to support decision-making in evaluation and selection of conceptual designs. The proposed approach has been implemented in a sustainable design decision-support software prototype. Illustrative examples are discussed in the paper to demonstrate the use of the approach and the prototype in conceptual design selection of a consumer product.

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.

This paper deals with the detailed conceptual design development of an autonomous vehicle, with the primary goal of transporting people with mobility problems or visual weakness, and thus avoid the risk of falls, tiredness, and fatigue; this aims to satisfy the needs of an increasing population with disabilities. An alternative solution is set for transfer based design methodology, which addresses each of the established requirements. The design stages established by Pahl & Beitz are described in detail, from the design proposal to functional prototype. The result of this work after evaluating the technical and financial analysis is a proposal of the functional design of the autonomous vehicle, which will be used in the main entrances of the Polytechnic University of Guanajuato (UPGTO). Regarding the autonomy of the vehicle, a vision system can be integrated if necessary as futre work, which will ensure its functionality and safety throughout its way; and thus be able to move through the main entrance towards the desired site.

To solve the problem of anticorrosion design in early stage of manufacture, a formal method of anticorrosion design was proposed, and a formal model of conceptual design of anticorrosive materials was established by using hierarchical structure, individual color sets and unified color sets. Basing on the reasoning matrices which were established by using polychromatic sets theory, a formal reasoning method was proposed to realize the formal reasoning from the functional requirements to the selection of final scheme. This formal method of conceptual design for anticorrosion based on the polychromatic sets can make the design process of anticorrosion standardized, and facilitate the formal description of the reasoning process and its expression and operation in computer. The method made some useful explorationfor the CAPP integration design of anticorrosion.

Rapid progress in the development of highly efficient nanoparticle-based construction technologies has not always been accompanied by a corresponding understanding of their effects on human health and ecosystems. Here, we compare toxicological effects of pristine TiO2, ZnO and SiO2, and coated SiO2 nanoparticles and evaluate their suitability as additives to consolidants of weathered construction materials. First, WST-1 and LDH assays were used to determine the viability of human alveolar A549 cells at various nanoparticle concentrations (0–250 μg mL−1). While the pristine TiO2 and coated SiO2 nanoparticles did not exhibit any cytotoxic effect up to the highest tested concentration, the pristine SiO2 and ZnO nanoparticles significantly reduced cell viability. Second, as all the developed nanoparticle-modified consolidants increased the mechanical strength of weathered sandstone, the decisive criterion for the selection of the most suitable nanoparticle additive was as low toxicity as possible. We believe that this approach will be of high importance for industry to identify materials representing top functional properties and low toxicity at an early stage of the product development.

This paper presents the application of methodology for ten bar single degree mechanisms and selecting the best among them at the conceptual design stage itself. This saves lot of time for one wants to carry away analysis for getting desired output of the mechanism at the design stage. The methodology has been applied to Tiscler robot hands successfully and has obtained the best mechanism in motion distribution among the links of the chain.
