Two Essays On Distribution, Fulfillment And Pricing Decisions For Retailers With E-Commerce Channel, Khosro Pichka
Two Essays On Distribution, Fulfillment And Pricing Decisions For Retailers With E-Commerce Channel, Khosro Pichka
Theses and Dissertations
E-commerce has grown rapidly in the past decade. In 2015, e-commerce was accounted for 7.2 percent of all retail sales in the U.S., which is massively higher than 0.2 percent in 1998 (U.S. Department of Commerce 2017). Worldwide e-commerce sales also show the same trend and reached $2.356 trillion in 2018 and are expected to grow steadily (Statista 2017). This trend has impacted major areas of operations management including supply chain management and revenue management. Today, e-commerce companies cannot satisfy their customers’ demand using traditional distribution systems. Therefore, retailers with e-commerce channels (e-tailers), cooperate with third party logistic service providers …

ABSTRACT
STRATEGIC NURSE ALLOCATION POLICIES UNDER DYNAMIC PATIENT DEMAND
by Osman T. Aydas
The University of Wisconsin-Milwaukee, 2017
Under the Supervision of Professor Anthony D. Ross
Several studies have shown a strong association between nurse staffing and patient outcomes. When a nursing unit is chronically short-staffed, nurses must maintain an intense pace to ensure that patients receive timely care. Over time this can result in nurse burnout, as well as dissatisfied patients and even medical errors. Improved accuracy in the allocation of nursing staff can mitigate these operational risks and improve patient outcomes. Nursing care is identified as the single …
Manufacturing Site Selection In The Global Context, Mahsa Mardikoraem Mardikoraem
Manufacturing Site Selection In The Global Context, Mahsa Mardikoraem Mardikoraem
Theses and Dissertations
The decision making regarding global site selection has been always a challenging and strategic problem. Recently, due to the globalization of the problem many new factors such as political, social, regulatory, government, environmental consideration, etc. gained importance in the decision making process. One of the goals in this thesis is to identify the relevant factors in manufacturing site selection and incorporate them into the data analysis. The collection of a wide range of factors that impact the manufacturing site selection problem at a country level, the quantification of these factors, and incorporation of them into the decision making process needs …
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 …
Production Scheduling In Integrated Steel Manufacturing, Wanxi Li
Production Scheduling In Integrated Steel Manufacturing, Wanxi Li
Theses and Dissertations
Steel manufacturing is both energy and capital intensive, and it includes multiple production stages, such as iron-making, steelmaking, and rolling. This dissertation investigates the order schedule coordination problem in a multi-stage manufacturing context. A mixed-integer linear programming model is proposed to generate operational (up to the minute) schedules for the steelmaking and rolling stages simultaneously. The proposed multi-stage scheduling model in integrated steel manufacturing can provide a broader view of the cost impact on the individual stages. It also extends the current order scheduling literature in steel manufacturing from a single-stage focus to the coordinated multi-stage focus. Experiments are introduced …
