In a surprise upset at the College of Engineering and Engineering Technology’s fall Senior Design…
DeKalb, Ill. — You could say a team of NIU’s graduating engineering students did their homework—and then some.
Taking top honors in the College of Engineering and Engineering Technology’s Spring 2018 Senior Design Day, the team is expected to save Aurora Specialty Textiles Group, Inc. roughly $100,000 a year.
Their efforts went beyond simply savings, with all those involved praising the team’s professionalism.
“They were super enthusiastic, and that was contagious,” said Marcia Ayala, vice president of the Yorkville-based textile company.
Tasked with increasing the company’s production times and improving cleaning methods, the team of Industrial and Systems Engineering graduates bested 38 other teams in NIU’s capstone competition. Faculty representatives chose the winning teams from each department, while the Engineering and Technology Alumni Society chose the overall winner.
Made up of Alexandra Hurtado of Aurora, Anthony Skrapits of Manhattan, Ill., and Alison Ward of Bolingbrook, the winning Range II Changeover Optimization project won both the overall Award of Excellence and first place in the Industrial and Systems Engineering category.
In the competition, teams tasked with real-world problems from local businesses and industries present recommendations typically applied at a later date.
“This company immediately applied the recommendations. Everything the team suggested, they implemented,” said Ehsan Asoudegi, assistant professor of Industrial and Systems Engineering, who advised the team along with Purush Damodaran, chair of Industrial and Systems Engineering.
“They took their jobs very seriously,” he said. “They worked long hours. They were very capable and communicated with everyone in the company, from lower to higher levels.”
Through observing and meeting with employees, the team found ways to cut down on the time in which machines were shut down for changeovers, or periods of time in which machines must be cleaned and prepped for various inks and chemicals. The changeover time was slightly longer than an hour, which translated into lost production time.
“I think through their efforts, we’ll get 30 to 50 percent improvement,” said John Schuster, director of operations for Aurora Specialty Textiles Group, Inc. He spoke in a video shown during the team’s final presentation.
“We got a lot of enthusiasm from every shift,” he said. “That is what I think led to the success of this project.”
The team estimates the yearly added production hours will create a savings of $80,000 to $95,000 annually.
Another $13,500 could be saved through new cleaning procedures, the team reported.
“I know from an industry standard, people aren’t going to do anything unless it’s practical,” team member Hurtado said. “You can try to explain theories, but it has to be super simple. You have to show actual savings. We crunched the numbers.”
By spending roughly $5,000 to $6,000, the company can see significant savings, the team found.
The team identified tasks that could be done before, during and after changeover times to cut down on those times and suggested the use of automatic spinning brushes with longer handles for cleaning instead of the abrasive pads employees were using. The new cleaning tools not only made the task quicker, but prevented employees from having to “crouch in these weird positions for a long time,” Hurtado said.
“Sometimes, people are so deep into the process, it’s difficult for them to step back and see what would help,” she said. “They need fresh eyes.”
