As the electronic engine technologies advances, the engine management tool has drawled attention for being one of the main efficiency improvement methodologies and for being applied on Diesel and Otto cycle engines. With the creation of hybrid vehicles there comes the need to manage several engines simultaneously in order to optimize the energy consumption and to reduce the waste emission, among other improvements. To accomplish this objectives are necessary to adapt this system to the driver's needs and to improve its controls. In order to doing so, we propose an intelligent approach for controlling this managing system using of artificial and computational intelligence techniques such as Bayesian Nets, Neural networks and Genetic Algorithms.

Anti-Collision Fuzzy Logic System for Automobile Vehicles

From simple collisions to major tragedies, car accidents happen every day. Automobile industry has been investing a lot in security systems (e.g., airbags, ABS brakes, vehicle proximity warning systems). However, drivers are still the ones who have to act in order to avoid collisions, by using the brakes or maneuvering the car. The purpose of this project is to develop an anti-collision logic that can be used on automobile vehicles to avoid collisions with both static and moving objects by interfering on the vehicle behavior. The control system is based on a fuzzy modeled controller using the MATLAB and Simulink tools from Math Works. The prototype chosen to test the logic was the Robotino, a mobile robot system made by Festo Didactic, and used for educational, training and research purposes. Robotino is able to integrate to Simulink tool natively, and provides out-of-the-box sensors and actuators, so the developers are able to focus the efforts on the software itself.

FMEA to Improve the Project Management

The FMEA methodology, widely used in projects through the application of DFMEA (Design FMEA), and processes for implementing the PFMEA (Process FMEA), represents a great opportunity to be used in Project Management, recording the experiences and lessons learned in current or past projects in order to prevent the recurrence of project failure. In this paper we are proposing the improvement of RFMEA (Risk FMEA) to prevent the automotive program mistakes. The main goal of the application of FMEA methodology on project management is to generate an organized way to document the experiences of existing projects and to transform the tacit knowledge of the team that develops projects into explicit knowledge, as well as, prevent future projects from existing critical failure modes. Due to globalization and the consequent need to launch products in the shortest possible time, project management has been essential for business survival.

SCRUM applied to foundry simulation projects

2023-02-10
2022-36-0068
Process simulation has a growing role in the casting industry, considered as an essential tool by most foundries that aim to develop systems that deliver quality parts, with the highest possible yield and lowest scrap rate. The challenges of performing casting simulation as part of tool construction projects for permanent molds are presented here. Real schedules from tooling companies are analyzed and their bottlenecks are explored. Using the concepts of agile project management and the Scrum framework applied to a cast part, it was possible to verify that integration between tool construction and simulation can increase quality and robustness with no impact to product development time.

Relation Among Virtual, Conventional and Rapid Prototyping Technologies.

In the process of development of a product, is important that the technologies of virtual, conventional and rapid prototyping can be used alternatively, this way it makes possible and facilitates the right development of a product. During the planning of the project, that happens before the beginning of any other activity, it is very important the knowledge of different process of prototyping, to decide what process will be used and which stage of the project it will satisfy the required necessities. Some mistakes in the choice of the process, or in not using the prototyping resource, will result in more time and costs for developing and less reliability of the project. So, the techniques of prototyping when used in a rational way, can be very important for making decisions during the development of the product.
