The paper lays out an experimental strategy for the nitriding process that optimizes a set of variables that have a bearing on the occurrence of nitriding cracks. The results demonstrate that several factors and interactions are relevant in the occurrence of nitriding cracks. The proposed strategy was found to be effective at achieving continuous improvement and stricter control.

The main objective of this research was to prioritize New Product Development (NPD) projects. NPD projects prioritization is a Multiple Criteria Decision Making (MCDM) problem. Analytic Hierarchy Process was applied to solve this decision-making problem. Mathematical Modeling, a research method of qualitative strategy was initially adopted. However, a mixed strategy was followed, as concepts of Case Study were included in the research. Therefore, that research did not the purpose to be exhaustive, that is, initially, one of research objectives was to model, with MCDM, a real case of NPD projects prioritization. Nevertheless, the decision-making model and results presented in this work can be considered by other companies, mainly from automotive sector.
