How to perform a simultaneous optimization with several response variables

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

Identification of Research gaps on Municipal Solid Waste Management from Data Indexed in the SCOPUS Database

This study aimed to identify the research gaps on the theme "Municipal Solid Waste Management", as from the analysis of articles indexed in the SCOPUS database. For this objective to be achieved, an applied research of exploratory nature and qualitative approach was carried out. It is noteworthy that, as method and technical procedures were adopted, respectively, the bibliographic research and the literature review. The data used in the analysis were obtained from the SCOPUS database in May 2018 and treated using Microsoft Excel® software. It is noteworthy that as a selection criterion, thirty papers indexed in this base that presented the highest number of citations were analyzed. As main results, it can be highlighted that the identified gaps were grouped into eight categories. Among the categories analyzed, one can highlight life cycle assessment, with ten gaps, and tools for municipal solid waste management, with eight. It is also noteworthy that the category "municipal solid waste management associated with other methodologies" occupies the second position, along with "tools for the management of municipal solid waste, indicating the lack of studies in the highlighted areas and pointing out the relevance of the theme for the academic environ

Scientific research trends about metaheuristics in process optimization and case study using the desirability function

This study aimed to identify the research gaps in Metaheuristics, taking into account the publications entered in a database in 2015 and to present a case study of a company in the Sul Fluminense region using the Desirability function. To achieve this goal, applied research of exploratory nature and qualitative approach was carried out, as well as another of quantitative nature. As method and technical procedures were the bibliographical research, some literature review, and an adopted case study respectively. As a contribution of this research, the holistic view of opportunities to carry out new investigations on the theme in question is pointed out. It is noteworthy that the identified study gaps after the research were prioritized and discriminated, highlighting the importance of the viability of metaheuristic algorithms, as well as their benefits for process optimization

Mapping Sustainability 4.0: contributions and limits of the symbiosis

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.

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

Using the attribute control chart to monitor a chemical manufacturing process

The chemical and pharmaceutical industries have quality as a prerequisite for the smooth running of their processes. Quality monitoring in this type of industrial activity is carried out using attribute control charts, among others. The aim of this article is to show a case study carried out in a company in the south of the state of Rio de Janeiro which used this type of control chart, more specifically the NP control chart, to monitor an antibiotic manufacturing process. The results showed the need for some adjustments and management actions will be taken to improve the process

Using statistical analysis to evaluate the water quality index in the Southern Region of the State of Rio de Janeiro
