This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water...
Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...
To address several challenges faced in healthcare, the Triple Aim (3A) was targeted by institutions to improve health outcomes and patient experience while reducing the costs of health. Process improvement techniques in manufacturing, such as Lean systems, were applied as tools to achieve the 3A framework. Unfortunately, the high level...
Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...
Highway work zones are extremely dangerous environments due to the presence of workers near high-speed traveling vehicles. This dynamic environment results in a disproportionate number of accidents that cause injury and casualty to both drivers and workers due primarily to vehicular intrusions into work zones. Several emerging work zone intrusion...
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...
Teamwork has become a popular operational strategy applied as part of workforce management plans in manufacturing and service industries. Teamwork has been commonly used in organizations to pursue different goals such as increase business operations agility, boost company productivity, improve quality in operations, increase company flexibility, promote collaborative learning, hasten...
Air traffic flow management over the U.S. airpsace is a difficult problem. Current management approaches lead to hundreds of thousands of hours of delay, costing billions of dollars annually. Weather and airport conditions may instigate this delay, but routing decisions balancing delay with congestion contribute significantly to the propagation of...
In this research, the comparative performance of permutation and non-permutation schedules is investigated in an assembly flow shop (AFS) with shift production, where a limited buffer storage is available between two machines. Most of the traditional scheduling problems consider continuous production, i.e., production occurs for 24 hours (3 * 8-hour...
YouTube has turned creating, watching, and interacting with videos into a mainstream activity and has substantial impact on modern society as the most popular video sharing site in the world. However, there is a lack of published research using statistically designed experiments which can aid content creators in making and...
