Objective: The objective of our project is to create a simple, yet effective, model of a solar dehydrator. Our model will have an efficient design and will be easily replicable for a child with the assistance of an adult. We hope that by designing this solar dehydrator we help children learn about solar energy and healthy food choices.

Decision Process

In this section we will compare the alternative solutions listed in section 4.2 based on the criteria listed in section 4.1. A Delphi matrix will be used to compare the solutions and their relative scores will be used to make our final decision. The designs are judged on a 0-50 scale. A higher score means that the design fulfills the specific requirements of that criterion. The criteria are then weighted relative to their importance in the overall design requirements, and these numbers are multiplied together to provide a final score. This final score can then be compared to the final scores of other criteria and used to determine our final decision. The Delphi matrix can be seen below in table 4-1.
