“…Therefore, even for a common product, with no added innovation, the main difficulty for the designers is to identify the suitable elements to be used in the design and a suitable combination of these elements or parts (Lawson, 2006). While customer needs (quality) represent an essential criterion in product design (Deselnicu et al, 2016), cost is also another important criterion (Eversheim et al, 1998). In addition, the environmental performance or the social impact of a product design has become important criteria (Mendler and Odell, 2000).…”

Design is a process through which customer needs are transformed into product or service specifications, and then used to develop a model or prototype. The prototype is tested, and modifications are brought to it before the production process starts. Moreover, the design process may be divided into different stages, starting from the definition of the customer needs, going through the conceptual design phase and ending up with the detailed design. In this article, we address the conceptual design phase, where the customer needs are assumed to be known. The proposed approach considers, based on customer needs, primary and secondary design criteria. Each design criterion has a set of predetermined possible values (options) from which the designer may select. Making the best selection of all the design features while satisfying the customer needs in terms of cost, quality (customer preference) and environmental performance is a combinatorial problem and therefore a decision-making framework would be helpful for the designers. In this article, the design criteria are evaluated using fuzzy technique for order preference by similarities to ideal solution based on cost, quality and environmental sustainability. A multiobjective and a single-objective binary programming models are then developed and solved, and their optimal solutions are obtained. The multiobjective solutions provide the decision makers with the possible trade-offs, whereas the single-objective model solution can be used as a final decision-making tool. The proposed approach is implemented in a user-friendly software developed by the authors. A case study is conducted using a baby car seat for which three main and six secondary design criteria are considered. The obtained results show the effectiveness of the approach used.

“…Because of their foot deformities, their biomechanical characteristics are different than the rest of the population (Deselnicu et al, 2016a) and constitute important indicators for a better understanding and analysis of their particular footwear necessities (Deselnicu et al, 2016b;Deselnicu et al, 2008). The elderly people, with a lot of illnesses caused by age, are mainly disposed to osteopathy (Galasso et al, 2009).…”

The paper presents the results of a fieldwork study conducted in order to analyze the variation of different biomechanical parameters of elderly women in Romania. The study has an exploratory and descriptive nature and uses quantitative methodology. The sample consisted of 100 elderly women from Romania, ranging from 55 to over 75 years of age. The collected data was analyzed using a statistic analysis software program. The analysis of variance demonstrated significant differences across weight groups in terms of biomechanical parameters such as toe off phase and support phase in the case of elderly women.

“…The loss of the ability to walk due to foot problem, not only produces physical limitations, but also has a significant impact on the persons's mental, social, and economic status (Helfand, 2015;Herghiligiu et al, 2016;Sarghie et al, 2016;Ionesi et al, 2014;Deselnicu et al, 2015). The world population is heading toward 10 billion people (Walker and Mesnard, 2009;Bougourd, 2015).…”

This paper approaches the relationship between obesity and foot disorders, an important topic in designing and producing preventive or palliative strategies to improve the quality of life for the elders. In spite the growth of old people, they are constrained to accept the footwear that the market is offering, which doesn't meet their special requirements in case of feet parameters. The analyzed sample consisted in 67 women, aged between 52-84 years old. By comparing the values of body mass index for the analyzed group it is demonstrated that with age, the weight increases for a significant number of women, going from overweight to obese. The authors performed as well, a descriptive statistics and a Pearson correlation between the body mass index and several plantar footprints parameters obtained in a previous research. As an important instrument, the body mass index can be used by footwear producers to modify and customize the last and the elderly shoes. The results of this study are important in various stages of producing footwear, highly adapted to the needs of different pathologies for the elderly consumers.
