- Improving the production process in a bakery industry: a simulation approachPublication . Setti, Fabiane K.; Geraldes, Carla A.S.; Almeida, João P.; Trentin, Marcelo GThe present study brings forward a simulation-based study of the production process of a Portuguese company that produces a wide range of bread. The main objective of this study was to analyse the different production processes of the company, and to propose further improvements to these, through the use of discrete event simulation. A relevant set of data was collected and four productive processes were chosen to be modelled using the Simulation Modelling based on Intelligent Objects software (Simio). The analysis of the developed models identi ed the need for improvements and di erent scenarios were created to this purpose. Among the obtained results, the creation of di erent mixed production scenarios allowed the maximisation of the production level while maintaining the current existing resources. The results of this work can be implemented in the company to increase production level without increasing costs since they do not involve the purchase of new equipment. In conclusion, this study highlights the ability of the simulation technique to analyse manufacturing processes throughout the creation of di erent scenarios providing insights on the production process optimising companies' productive performance.
- Analysis and optimisation of a production line using discrete simulationPublication . Setti, Fabiane Kupchak; Geraldes, Carla A.S.; Almeida, João P.; Trentin, Marcelo G.This study presents a simulation-based procedure to analyse a production line of a metalworking company. We use a simulation tool, ProModel R software, to reproduce the existing production line layout of the company best-selling product which represents about 70% of the total sales. Our purpose is to get information about the existing system behaviour, and to find strategies to increase actual production level to meet the market’s demand. Based on an initial simulation model, different production scenarios were proposed and results have shown that it is possible to increase the production level allowing to meet the increasing demand for the product. The following changes in the production system were considered: (i) the use of intermediate stock of work-in-process items, (ii) the introduction of new equipment, and (iii) a mixed strategy where the introduction of new equipment is combined with the use of intermediate stock of work-in-process items. In summary, this research exhibits the flexibility of the simulation technique to address manufacturing problems throughout the creation of different scenarios providing some of the behaviour of the systems allowing the anticipation of final outputs.

We use a simulation tool, SIMIO software, to reproduce the existing production layout of the company. Our purpose is to gather relevant information about the actual production system behaviour, and to find strategies to increase the production level to meet the market demand. Based on initial simulation model, some production scenarios were developed involving the production of different products. The analysis of the developed models highlighted the need for improvements. Among the obtained results, the creation of different mixed production scenarios allowed to increase the production level while maintaining the current existing resources. The results of this work can be easily implemented in the company in order to increase the production level without increasing costs since they do not involve the purchase of new equipment.
