QUALITY CONTROL TOOLS IN THE ANALYSIS OF COVID-19 CAUSED PROBLEMS

Abstract

Quality control tools are taught in engineering careers to analyze and try to solve problems in the production of goods and in the performance of service businesses. Those tools can be used to analyze and understand many problems. The coronavirus pandemic has caused many problems around the world, like many people infected in people’s agglomerations in public transportation, in celebrations like parties, in political rallies and in public markets because of the people not wearing masks. A Pareto diagram clearly shows the most dangerous comorbidities in case of covid-19 infection. A lot of doctors and nurses have been contagious around the world in many cases because of lack of protection materials for them, hopefully health and safety procedures (check lists) and Poka Yoke devices are being created and implemented to reduced contagion. In this paper we identified and analyzed some covid-19 caused problems using basic quality control tools and for some cases we proposed solutions to them. Examples of a Pareto Diagram in analyzing the death rate in age ranges is used to explain the decrement in deaths in the United States of America if certain age groups are first vaccinated, an Ishikawa Diagram is used to analyze the ineffective distant learning in Mexico, a Check List is elaborated to avoid contagion in shopping and a Dispersion Diagram is used to find a relation between the number of contagious and the number of deaths in many countries of the world. Some other tools are briefly explained and some problems which could be analyzed with those are identified. The examples could enhance the interest of the students in learning the usefulness of those tools in a variety of fields.
