Uso de modelo de referência para melhoria do processo de fabricação de papel kraft

Abstract

The paper industry is struggling to stabilize and maintain the quality standards demanded by customers. These difficulties vary depending on the degree of organization and automation of the production process. Through quality testing can determine how the process variables can influence the final product. In the case of Kraft paper production, product quality is evaluated through the analysis of mechanical strength, watery mass level, humidity, among others. Another relevant factor is the raw material used in the manufacture of paper, which has different origins (mechanical pulp, pulp and industrial and domestic waste paper), thus directly influencing the process control. The information generated during the production control and quality can take timely corrective actions and limited effect. Regulating the flow of data leads to better quality information to control production. An alternative may be to use a reference model used in the Process of Product Development to organize a production process and discipline. With the aid of a reference model seeks to have a broader view and look at each step of production, which do not have the tools and traditional methods of production management (eg, MASP). Was use of interviews (conducted with individuals responsible for the control of production) as well as questionnaires (answered by the same people) in order to know the details of paper production at the company studied. We performed comparison of the information obtained through interviews and questionnaires with the observation and monitoring of the production process seeking to verify the accuracy of the information. We collected laboratory data quality company to identify non-compliances that should be controlled. All this information was used to feed the Reference Model Fractal Clover in the search for improvement in the manufacturing process of the Kraft paper. The results showed that the company is studying is extremely dependent on tacit knowledge of employees. Clover Fractal model indicated some possibilities for improvement, respecting the philosophy of the company. The model predicted ways to harness the tacit knowledge of people involved in the production (which is a knowledge of the strengths of the company) and suggested raising the level of instrumentation, production equipment seeking to improve the control of the production process.
