Organics To You - Optimization Of Produce Bins, Rassaniya Lerdphayakkarat, Chuan Chieh Lu, Jon Roschke, Juliana Suzuki, Jessie Truong

Engineering and Technology Management Student Projects

Organics to You (www.organicstoyou.org ) is a produce delivery company that focuses on bringing organic local food from local farms straight to the homes, schools, and businesses of its clients. Each week a "Small Bin" is created using different varieties of local produce from various farms. Customers receive a bin that contains 12-14 varieties of produce with 2-6 "servings" of each variety (e.g., 1 melon, 4 apples, 1 head of lettuce, 2 lbs potatoes, etc).

Our objective is to optimize the contents of the “Small Bin”. The decision we want to make is how much of each variety do …

Engineering and Technology Management Faculty Publications and Presentations

The national laboratories in countries that are latecomers to advanced technological development are considered a significant source of scientific knowledge and technology for local industries that the national government deems strategic and for developing the country’s infrastructure. This knowledge comes from both inside and outside the national laboratories. We investigate the relative impact of internal and external sources of knowledge on the performance of the national laboratories of a rapidly developing country, whose stated missions are 1) satisfying the needs of targeted local technology users; 2) commercialization of technology; and 3) developing a long-term R&D capability for the country. We …

Dissertations and Theses

Innovation is one of the most important sources of competitive advantage. It helps a company to fuel the growth of new products and services, sustain incumbents, create new markets, transform industries, and promote the global competitiveness of nations. Because of its importance, companies need to manage innovation. It is very important for a company to be able to measure its innovativeness because one cannot effectively manage without measurement. A good measurement model will help a company to understand its current capability and identify areas that need improvement.

In this research a systematic approach was developed for a company to measure …

Technology Forecasting For Wireless Communication, Timothy R. Anderson, Tugrul Unsal Daim, Jisun Kim

Engineering and Technology Management Faculty Publications and Presentations

Wireless communications technologies have undergone rapid changes over the last 30 years from analog approaches to digital-based systems. These technologies have improved on many fronts including bandwidth, range, and power requirements. Development of new telecommunications technologies is critical. It requires many years of efforts. In order to be competitive, it is critical to establish a roadmap of future technologies. This paper presents a framework to characterize, assess and forecast the wireless communication technologies. A DEA-based methodology was used for predicting the state-of-the-art in future wireless communications technologies.
