A problem facing the product development community is developing simultaneous solutions of response variables (to several properties) that depends on a number of independent variables or sets of responses. Harrington, among others, addressed this problem and presented a desirability function with a functional approach. Derringer and Suich altered their approach and illustrated how multiple variables can be transformed into a convenience function. This work redid the calculation performed by them using another software and made a comparative discussion of the results found.

The history of industry is marked by four industrial revolutions, and society is now in the consolidation of its fourth, which provides opportunities for sustainability, such as reduction in environmental impact and social inclusion. This article aims to identify the main authors, countries, articles, and research gaps on the theme "Industry 4.0 and Corporate Sustainability"; and to draw up a mind map with the research trends, through the analysis of the documents that are indexed in the Scopus database. Among the main trends that were identified in this article are: Industry 4.0 as a tool to support sustainability; Intersection and boundaries between sustainability and industry 4.0; Development of industry 4.0 along the lines of sustainability; Management applied in sustainable industry 4.0. The main contribution applied was the exposure of the possibilities that companies can implement, both in relation to sustainability in the development of innovative technologies, and the use of technologies to strengthen the pillars of sustainability.

Purpose: The present paper addressed the application of the Six Sigma method for process management to reduce the variability and scrap of packages manufactured at a company located in the city of Rio de Janeiro. Methodology/Approach: Exploratory research was conducted to understand the context, analyse, and create familiarity with the problems identified in the company, making them more explicit. Findings: Through Define, Measure, Analyze, Improve, Control (DMAIC) the company was able to identify the main causes of customer complaints and the factors that led to these complaints. Using management tools, it was possible to solve the problems with packaging outside the specifications, which was the reason for complaints from customers. The benefits of this research were the identification and analysis of the quality management tools. Research Limitation/Implication: The present research had as a limitation the application of the method is only one company, so it is proposed as a future study of the application in different production processes of different organizations. Originality/Value of paper: It was evidenced that there is a positive relationship between the application of Quality management methods and company billing, as there was an increase of 1.7% in company billing. In past surveys, new possibilities for improvement to be addressed emerged, making the team aware of the need to continue the process of continuous improvement.

Purpose: This paper aims to introduce an economic instrument called Theory of Pollution Credit Certificates in the management of municipal solid waste in Brazil, in order to create opportunities to achieve the goal established in the above mentioned policy at lowest possible social costs.        Methodology/Approach: The methodology adopted has as a starting point the “constructo” of a scenario in which a city comprised of five brazilian districts produces its urban solid waste made up of 50% organic material. In the proposed scenario, similar to what happens in practice, a fee for collection and treatment of organic material would be charged for two different situations. Findings: The result showed that the use of Pollution Credit Certificates Theory has a better cost-effectiveness for solid waste management because it allows reaching the environmental goal at a lower cost to society. Research Limitation/Implication: Subjectivity of the analysis, due to the “constructo” proposition in the studies. Originality/Value of paper: From the results obtained, we inferred that the use of the Pollution Certificates Theory for the management of brazilian municipal solid waste benefits from economies of scale as it allows in the scenario determined, that districts sell their spaces at the landfill and parallel to this, to promote the practice of composting organic waste in the municipality.
