Objectives
Description:
Transmit knowledge about the new paradigms of Integrated Product Development and Concurrent Engineering. The course also deals with the enabling technologies to apply those paradigms, namely CAD, CAE, CAM, CAPP, PDM systems. The main output of this course is a project work developed by the student along the semester applying and using all the referred to technologies.
Knowledge
- Fundamental principles of Integrated Product Development (IPD)
-Enabling technologies for IPD
- Organization and Management of product data (PDM)
- Team organization and management.
Do
- Solution evaluation and selection of the adequate technologies
- Use specialized software to support the case studies of product development
- Team work management
Soft skills
- Team work
- Time management
- Technical writing
- Oral presentations
- Develop critical thinking
Prerequisites
The students must have good acquaintance with personal computers and the most common software. Knowledge of Solidworks is highly desired.

Teaching method
The course encompasses a number of lectures of different themes and subjects as the starting point for the research required to the students. The presentations use multimedia technologies and will be available on the site of the course.
Tutorial classes on the different software tools for the Integrated Product Development, the students will perform several activities with a number of examples. Support by the tutors is provided during the course of these activities.
In order to provide a systematic progress of the student, all the classes are compulsory. The student has to attend at least to 10 out of 14 classes in each type (Lectures and Tutorials) during the semester. This attendance influences the grading.
Evaluation method
1.1 - Relevant participation and sistematic presence in classes 1.05 - Relevant participation with some presence in classes 1.0 - Good presence in classes, but low intervention 0.9 - Few presences in class (<15% of total)
- Continuous evaluation in the tutorial classes where the students perform different activities (CP);
- A term paper (individual) based on one of the proposed topics. The intention is to evaluate the synthesis capability of the sutdent. The student will be invited to give a short class on the topic, using the first part of the official lecture. In the 2nd part the Professor will comment, correct and add complementaty material (TM);
- Final Project concerning the Development of a given product, developed by a group of students. This intends to evaluate the knowledge integration capability, their capacity to deal with complex situations and team work (TF).
- Oral presentation and discussion of Final Project (TFO).
- The attendance to classes and the active intervention of students in the classes referred to in the secon item defines an affecting factor to the overall grade (FM):
