Resumo: | This paper aims to apply the zip code concept in real data of a casting industry in Santa Catarina, in order to identify features and particularities of this process, as well as improving useful qualities for employees who monitories the company procedure, or even other people who work and deal with similar processes. The paper uses basically the construction of control charts, which are more suitable to the sample collecting features made in the company, besides calculating its capacity, what brings interesting issues for the main identified problems which must be improved. The paper limits to perform statistical analysis and consequently to build conjectures based on the information provided by the company, believing in the veracity of it, without setting aside any information or inference acquired through a more scientific, technical approach, not just empirical, of the data. This is the way theoretical concepts found in literature and practical procedures watched in the company will be discussed, always aiming for validations that indicate the route of new researches, as well as exploring new opportunities decurrently of the adoption of other procedures. Key Words: Cumulative-Sum Control Chart; Exponentially Weighted Moving Average Control Chart; Process Capability Ratios. |

Mais precisamente, nosso objetivo consiste em analisar a qualidade e a capacidade de produção da indústria, visando identificar particularidades e características do processo, assim como oportunidades de melhorias úteis aos operadores e responsáveis pelo monitoramento do processo na empresa, ou mesmo para outras pessoas que trabalhem e lidem com processos similares. Nesse estudo, utilizamos alguns dos principais tipos de gráficos de controle já consagrados na literatura, tais como o gráfico de controle para observações individuais; o gráfico da amplitude móvel; o gráfico da média móvel exponencialmente ponderada e o gráfico da soma cumulativa. O trabalho limita-se apenas a realizar análises estatísticas sobre os dados fornecidos para estudo e possivelmente construir conjecturas baseadas nas informações transmitidas pela empresa, esperando e acreditando na fidedignidade e veracidade das mesmas, sem, no entanto desprezar toda e qualquer informação e/ou inferência adquirida a partir de um olhar mais técnico científico e não tanto empírico dos dados. Nesse artigo, nós não temos a pretensão de desenvolver métodos e modelos estatísticos mais robustos para realizar tal estudo.
