Warranty Period And Product Price Optimization For Remanufactured Products, Yuxi Liu
Warranty Period And Product Price Optimization For Remanufactured Products, Yuxi Liu
Theses and Dissertations
This study considers a remanufactured electrical product under a tiered warranty policy. Warranty is key in ensuring a good manufacturer—consumer relationship. Manufacturers hope to minimize warranty costs while consumers believe that good warranty promises better product quality and reliability. This Thesis presents an optimal warranty period from the perspective of a manufacturer to maximize the total expected profits, while ensuring sustained consumer relation. We use real data from a local company with a global supply chain to provide a numerical example.
Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Theses and Dissertations
This thesis presents methods for efficiently controlling a buffer that is located between two non-synchronized manufacturing processes. Several machines with different cycle times and/or batch sizes perform each manufacturing process. The overall operation cycles every T time units. The first objective of the problem is to minimize the average buffer inventory level during one cycle. The second objective is to minimize the maximum inventory level observed at any point during the cycle. This new optimization problem has not been previously considered in the literature. An integer program is developed to model this problem. In addition, two heuristic methods—a simulated annealing …
Pragmatic Divestment Of Kc-135 Navigators In The Special Operations Air Refueling Mission, Andrew P. Nation
Pragmatic Divestment Of Kc-135 Navigators In The Special Operations Air Refueling Mission, Andrew P. Nation
Theses and Dissertations
In the late 1990s, the Air Force eliminated over 200 KC-135 navigators, leaving 50 remaining for the aircraft's most complex Special Operations Air Refueling (SOAR) mission. As the Air Force unveils the KC-46 Pegasus, this mission will continue but without a position for the navigator. Instead, navigators will undergo divestment as the SOAR mission transfers to the KC-46. Current plans indicate navigators will not only remain as the KC-46 arrives, but inbound navigators will continue arriving until 2018. This thesis applies the Delphi method, a process eliciting analysis anonymously from a panel of experts, in order to examine the elements …
