From April 26th to 29th, 2013, the 31st "Tsinghua Challenge Cup" Exhibition was held in the South Square of the swimming pool.
In the exhibition, many teachers and students spoke highly of the exhibition works of the Department of Industrial Engineering. After the exhibition opened in the morning of 28th, Tsinghua President Chen Jining came to exhibition. He went straight to our exhibition area, listening to introduction of students from the Department of Science. He stopped in front of the "Shaking Bus" and the campus real-time bus display screen, asked technical details of the project; President Chen also showed great interest in the bus query software using his mobile phone. Then, Peng Qijia, the author of First prize works "i Travel Tsinghua", presented his work to Chen Jining. When Mr. Chen knew it was the first campus tour application, and was developed independently by the students, he was very happy and expressed his praise without hesitation. During the visit, President Chen spoke highly of the exhibition results of the Industrial Engineering Department, and confirmed the useful exploration of innovation teaching, experimental practice teaching and challenge teaching in recent years. He hoped that students would make full use of resources provided by the university, and turn their own ideas into practical results through hands-on practice. Besides, Tsinghua University Council Vice Chairperson Shi Zongkai also came to our exhibition area, and talked to our students, and encouraged everyone to make persistent efforts to create more excellent works.

In the exhibition, the Department of Industrial Engineering exhibited a total of 10 works, including a school SRT first prize work, a first prize work of "Challenge Cup", and 3 third prize works as well as 3 four course design works.
Among them, "Shaking Bus" - Offline Bus Inquiry System" and "Tsinghua Campus Bus Real-time Query System" (t.yygongjiao.com), the first prize works of SRT, were very popular with audiences. The two works were developed by iOptimize research group which was led by associate professor Jiang Hai. Especially, "Shaking Bus" was the only mobile phone application available in app store to perform "location to the location" offline query about bus and subway transfer. After the input of destination, users could get the bus and subway transfer just by shaking their phone. What"s more, the campus bus real-time query system developed by the research team was the first real-time bus positioning application. It helped users accurately understand campus bus real-time location and driving direction through satellite positioning, providing great convenience for school travel.

Besides, "i Travel Tsinghua-personalized Tsinghua campus tour recommended mobile applications", the first prize work of "Challenge Cup", attracted a lot of viewers. Compared to the characteristics of general tour guide application, such as personalized navigation, the lack of scenic area applications and unable to achieve online functionalities, "i Travel Tsinghua" was very fast and convenient, and was also more caring for individual needs of tourists. In detail, it offered a variety of personalized features such as self-selection points, increased space or time constraints, self-selected travel paths meeting the requirements, and ratings of attractions. In addition, the combination of two-dimensional code technology and web page introduction as well as scoring system, enabled the synchronization of the tour and the network explanation, which made it easy for visitors to score and thus provided a reference for other visitors.

Furthermore, "Pet Companion", "Green Humidifier" and "Challenge Cup" entries "Spare Parts for Intermittent Demand Forecasting Method and Inventory Strategy Research", "WebGIS-based Distribution Dispatching System", "Family Health management system Based on Portable Medical Electronic Equipment", "The Head of E Family- Home Appliances Energy Calculator" and "Interactive Social Networking Shopping Platform" were displayed through video, panels or physically at the exhibition. Thanks to the introduction and guidance by the Department of Science and Technology students, the ingenious ideas and excellent practicality of the works were widely acknowledged. Excitingly, many business executives left their contacts, hoping to get in touch with some of the authors through the Department of Science and Technology.
