- A model of integration ISO 9001 with Lean six sigma and main benefits achievedPublication . Sá, José Carlos; Vaz, Sílvia; Carvalho, Orlancina; Lima, Vanda; Morgado, Luísa; Fonseca, Luís; Doiro, Manuel; Santos, GilbertoThe main purpose of this article is to depict the integration of Lean tools with requirements of ISO 9001:2015 standard as an operationalisation and support tool for a Quality Management System (QMS). The research was carried out through a questionnaire, which was sent to 2040 Portuguese companies. From the two hundred responses, 77 of them were validated (companies certified by at least one quality management system and which simultaneously have lean six sigma (LSS) tools and/or techniques implemented) corresponding to the sample of this study. Additionally, the research was also based on a case study in a footwear company where the model was applied. This research proposes a model for integrating Lean tools and requirements of ISO 9001:2015. This integration allows the QMS to become more practical and dynamic, reinforcing the creation of value for the organisation. As main benefits, we can highlight, among others: improvement of problem solving, waste reduction, improvement in internal communication, and increase in productivity. Thisarticle aims at becoming a relevant contribution to business management as it displays the main tools and methodologies to implement and sustain a QMS.
- Production Process Analysis and Improvement of Corrugated Cardboard IndustryPublication . Pereira, Maria Teresa Ribeiro; Neves, A.S.L.; Silva, F.J.G.; Godina, R.; Morgado, Luísa; Pinto, Gustavo FilipeThis work was developed into a corrugated cardboard industrial company. In this sector are produced plans resulting from the union between corrugated cardboard produced and the sheets printed in the previous sector. The PDCA cycle was the main methodology used in this work. Firstly, the initial state of the production was analyzed by data collection in both existent lines and it was concluded that a great variability of the parameters was being used in the process for similar works. The main problems in the process were identified and it was concluded that warp and detached plans were the main reasons for concern. It was implemented a set of measures to reduce these incidences. Control charts were implemented to the starch glue and through the analysis of these charts and cause-effect diagrams several changes to the starch glue circuit and to its own recipe were implemented. The steam pressure of the boiler was reduced from 12 bar to 8 bar and a table with temperatures regarding each paper weight was implemented. The results obtained show that the percentage of waste in the sector was reduced from values ranging between 9 and 12% to values around 4%. Regarding starch glue consumption, it dropped from 11 g/m2 to 8 g/m2. The energy consumption, namely gas, showed a saving of 9%. Thus, this work represents an important contribute to the sector, allowing energy savings and quality and competitiveness improvements.
