New product development (NPD) is a managerial process, performed by many activities. The purpose of this paper is to present the application of the analytic hierarchy process (AHP) to prioritise activities of NPD for manufacturing companies of electronic products. Mathematical modelling was the research method adopted. An electronics cluster located in the southeast region of Brazil was studied. Therefore, 10 of the 42 activities from an NPD model were suggested to be excluded for the electronics companies. These activities have less than 0.5% overall priority. The results from the AHP application were welcomed by the companies’ NPD experts.

A pesquisa-ação é um método de pesquisa qualitativa que cada vez mais se destaca como estratégia de pesquisa adotada em engenharia de produção. Contudo, esse método sofre com preconceitos a respeito do seu mérito científico, bem como com uma indefinição de como sua condução pode ser validada. Visando minimizar essas lacunas da literatura, a partir de uma pesquisa de cunho conceitual-teórico, o presente trabalho visa propor um processo para o planejamento e condução de pesquisas na engenharia da produção por meio da pesquisa-ação. Consideram-se como contribuições científicas do presente trabalho a discussão acerca das formas de iniciação e das etapas de validação das pesquisas que empregam o método da pesquisa-ação. Conclui-se que, dentro do paradigma científico do realismo, os critérios mais adequados para a validação da pesquisa-ação são a adequação ontológica, a validade contingente, a percepção múltipla dos participantes, a fidedignidade metodológica, a generalização analítica e a validade do construto.

The ISO 9001 standard is considered as an effective tool to support a quality management system (QMS). A steady growth in the number of ISO 9001 issued certificates is observed worldwide, confirming the interest of companies in this approach. However, information regarding this behaviour over time in the American Continent is scarce. This paper presents a set of qualitative and quantitative analyses related to the ISO 9001 certification (globally and at the country level of the Americas), the use of this standard in countries that were part of the ISO Survey 2011 and modelling the ISO 9001 certification for American countries, in order to characterise through mathematical models, the evolution of the certification process and to identify factors that influence the ISO 9001 issued certificates in the various countries analysed. Based on the work developed, a positive relationship was found between the number of issued certificates in each country per 1000 inhabitants and the indicators of economic development (Gross National Income Per Capita). It is determined that the total reserves of a country is an economic variable that directly affects the number of issued certificates, a finding not observed in other forecasting models.

Purpose – The purpose of this paper is to propose a systematic study to formulate the cost of prototypes manufactured through rapid prototyping (RP) an fused deposition modeling (FDM) 3D printer in a university lab. Design/methodology/approach – The paper has a theoretical-conceptual approach. This approach is carried out by studying and proposing a methodology for calculating the cost of pieces prototyped an FDM 3D printer. Findings – This work originated from a gap in literature to establish a way to calculate the price of RP pieces from FDM 3D printers in universities' labs, since no similar work has dealt with this RP technology and has not taken into account the costs of post-processing step. The results suggest that the formulation may be used to calculate price of prototyped pieces through FDM 3D printer. Research limitations/implications – The systematic approach proposed by this research to formulate cost for the RP pieces is initially oriented only to modelling technique by FDM 3D printer. Considerations on operator's and designer's hourly rates are those practiced in Brazil, which may differ from other countries. Originality/value – The paper's scientific contribution is a specific formulation to calculate price of prototyped pieces through FDM considering the post-processing way, which differs from previous published works. The formulation implies that the execution times and the amount of material used were obtained by internal calculation of the tested machine. This is different from what has been already studied by previous literature which considers an index that encompasses the machine operation cost in function of time. It is aimed that the results obtained here are accurate, since error margins of the process variables are reduced.
