The United States Department of Defense has developed a project with the goal of developing a Pre-positioned Expeditionary Assistance Kit (PEAK), supplying essential services in times of crises.  The PEAK includes: power generation, water purification, communication and a cooking system. The kit must leverage existing technology and make maximum use of commercial, off-the-shelf (COTS) technology.  Power must be generated through renewable resources.

Warrior Innovative Design (WID) has completed four milestones (MS) to complete this project. MS1 includes an investigation of the problem statement to develop specifications, criteria, and constraints. WID developed and analyzed four comparable designs in MS2 that could meet the needs of a PEAK. Two different decision matrix processes were used to select the final design in MS3.  The first decision matrix with yes or no entries was applied to all four designs to find out whether or not each design met the demands of the specifications and constraints. The second decision matrix was called a Pugh Analysis, with number entries applied to all designs using these criteria. The weighing percentage was assigned a numerical value to each category of criteria used to justify the decision making process.

Design 1 was confirmed by the Pugh analysis to be the best design. The descending order was Design 4, Design 2, and Design 3.  Final design, Design 1, has an ultraviolet water purifier, a solar cooker and a 1 kW solar power generator. The alternative components can be found under Section 2 of this report under the Alternative Design Concepts section. The Failure Mode and Effect Analysis (FMEA) method was used for conducting the safety analysis in MS3.

The improvement of the final design was developed in MS4.  WID worked on improving the final design in weight and volume since MS3. The overall cost and weight of the final design is approximately US$37,040.5 and732.6 lb, respectively.
