Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...
An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...
Whey is co-product of cheese production and is produced at 9:1 whey to cheese ratio. Whey is broadly classified into two types, sweet and acid whey. Large cheese manufacturers have developed whey processing techniques to convert sweet whey into value added products such as protein powders and emulsifiers. Acid whey...
Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...
Organizations are constantly looking for innovative strategies to face more stringent competitive environments and the ever increasing market globalization. An alternative these organizations can pursue to respond to these challenges is to optimize their supply chain network (SCN). Important considerations when optimizing a SCN involve determining locations for plants and...
A flexible flowshop, comprised of one or more stages having unrelated parallel machines, is investigated in this research. Unrelated parallel machines can perform the same function but have different capacity or capability. Since this problem is motivated by industry research, dynamic job release times and dynamic machine availability times have...
Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...
The application of lean to new product development (NPD) processes has been claimed to generate positive impact on NPD performance. There are very few empirical studies, however, on how organizations should apply lean practices or on the exact nature of the impact of lean on NPD performance. To further understand...
Small business energy analysts often specialize in one aspect of the business. This specialized focus is done by necessity due to scarcity of resources and to maintain a proprietary market niche. However, this specialized focus results in a growth inhibitor due to their lack of ability to address all the...
This research is an effort to explore the nature of good work, a concept that describes work that is beneficial to the physical, psychological, and social dimensions of its stakeholders, including and especially the worker. This effort is divided into four distinct parts. First, the construct of good work is...
