“…In the same way, one also noticed that, once the minimum buffer capacity mentioned in Resano and Pérez [5,6] was reached, a continuous supply of transport and assembly pallets to machines was assured. In the context of this work, the validation of the simulation model proposed was confirmed, on the basis of these two presuppositions [18,28,29].…”

“…With this objective in mind, a support system for decision-making was developed; this enables the automatic generation of different simulation models. In the initial stage of simulation, the user is able to interact with the system to be developed, through the introduction of various parameters such as [18,28,29]: the four-door car ratio (x); the processing time for each machine; the production sequence in accordance with each type of car (two-or four-door); the speed and length of the intermediate buffers formed by conveyors; simulation time; the number of pallets circulating on the first three closed loops. Figure 30.7 shows an example of a screenshot of the simulation model developed in Arena ® incorporating the abovementioned parameters.…”

“…A simulation-based decision-making process allows for the modeling and analysis of the performance of complex systems and processes [6,[23][24][25][26]. Simulation constitutes an instrument, providing the user with possibilities that include developing a model based on a real system, predicting actions ensuing from previously collected data, predicting areas with the potential for improvement, and evaluating the impact of different types of strategies on these and other areas [27][28][29][30][31][32][33]. For these reasons, simulation was employed extensively within the five distinct phases in our research method.…”

To remain competitive, companies must continuously improve the processes at hand, be they administrative, production, or logistics. The objective of the study described in this paper was to develop a decision-making tool based on a simulation model to support the production of knits and damask fabrics. The tool was used to test different control strategies for material flow, from the raw material warehouse to the finished product warehouse, and thus can also be used to evaluate the impacts of these strategies on the productivity. The data upon which the decision support tool was built were collected from five sectors of the plant: the raw material warehouse, knit production, damask production, finishing work, and the finished product warehouse. The decision support tool met the objectives of the project, with all five strategies developed showing positive results. Knit and damask production rates increased by up to 8% and 44%, respectively, and a reduction of 75% was observed in the waiting time on the point of entry to the finishing work area, compared to the company’s existing system.

“…Simulation has also been used to try to create models that allow the grouping of parts to be machined [34,35]. The principles do not differ markedly from others used in the assembly lines [36], but they do not fully integrate the needs considered as main requirements in the problem now formulated. A very deep review of the literature revealed that there is a clear gap in this matter, which justified the accomplishment of this work.…”

The production of stamping dies requires the manufacture of numerous components, many of which have similar dimensions. However, because they are almost all different, this brings added problems in the acquisition of materials, and in their machining, the main process used in the manufacture of these components. Most SMEs do not have production systems properly organized to manage the machining of these components in the most cost-effective way. The purpose of this work is to provide a novel tool able to re-organize the machining operations in the production of dies for stamping operations, saving time and allowing an easy way to extend the autonomous machining time. This work follows an empirical approach resulting from the experience and attempts to optimize machining operations in the production of stamping dies. A flowchart was developed, acting as guidelines to select if the set of parts to be manufactured can integrate the approach designed. The approach is validated by two case studies presented in the paper.
