Quantifying The Effects Of Customer Predictability On Battery Energy Storage System Cost And Emissions, Mudit Bhadresh Purohit
Quantifying The Effects Of Customer Predictability On Battery Energy Storage System Cost And Emissions, Mudit Bhadresh Purohit
Theses
Electricity providers are using variable pricing to encourage customers to shift energy consumption from “peak” times. This presents a great opportunity for the customers to reduce their bills using this variable pricing strategy coupled with a battery energy storage system (BESS). The schedule of charging and discharging the BESS depends on the forecasted customer demand data. Forecasts are bound to have a certain degree of error associated with them, and hence it becomes important to understand the effect of these forecasting errors on the cost and the emissions associated with scheduling of the BESS. In this work, a method has …
Using Reduced Graphs For Efficient Hls Scheduling, Stephanie Soldavini
Using Reduced Graphs For Efficient Hls Scheduling, Stephanie Soldavini
Theses
High-Level Synthesis (HLS) is the process of inferring a digital circuit from a high-level algorithmic description provided as a software implementation, usually in C/C++. HLS tools will parse the input code and then perform three main steps: allocation, scheduling, and binding. This results in a hardware architecture which can then be represented as a Register-Transfer Level (RTL) model using a Hardware Description Language (HDL), such as VHDL or Verilog. Allocation determines the amount of resources needed, scheduling finds the order in which operations should occur, and binding maps operations onto the allocated hardware resources. Two main challenges of scheduling are …
Home Energy Management System For Demand Response Purposes, Isra Adam Hussein Haroun
Home Energy Management System For Demand Response Purposes, Isra Adam Hussein Haroun
Theses
The growing demand for electricity has led to increasing efforts to generate and satisfy the rising demand. This led to suppliers attempting to reduce consumption with the help of the users. Requests to shift unnecessary loads off the peak hours, using other sources of generators to supply the grid while offering incentives to the users have made a significant effect. Furthermore, automated solutions were implemented with the help of Home Energy Management Systems (HEMS) where the user can remotely manage household loads to reduce consumption or cost. Demand Response (DR) is the process of reducing power consumption in a response …
Optimization Of Residential Battery Energy Storage System Scheduling For Cost And Emissions Reductions, Zachary Olivieri
Optimization Of Residential Battery Energy Storage System Scheduling For Cost And Emissions Reductions, Zachary Olivieri
Theses
The introduction of dynamic electricity pricing structures such as Time of Use (TOU) rates and Day Ahead Pricing (DAP) in residential markets has created the possibility for customers to reduce their electric bills by using energy storage systems for load shifting and/or peak load shaving. While there are numerous system designs and model formulations for minimizing electric bills under these rate structures the use of these systems has the potential to cause an increase in emissions from the electricity system. The Increase in emissions is linked to the difference in fuel mix of marginal generators throughout the day as well …
Modeling And Analysis Of Or Nurse Scheduling Using Mathematical Programming And Simulation, Clayton Tontarski
Modeling And Analysis Of Or Nurse Scheduling Using Mathematical Programming And Simulation, Clayton Tontarski
Theses
Nurse scheduling is a complex problem. The act of assigning each nurse to a specific shift for each day of a scheduling horizon, while ensuring to fulfill the demand of the operating rooms (ORs) is very time consuming. Current methods used in practice often develop solutions that are suboptimal, resulting in low nurse utilization, low nurse satisfaction, patient delays, or overtime pay for nurses. In this paper we propose an approach that utilizes simulation, simulation-based optimization, and mathematical programming as tools for solving complex nurse scheduling problems. We discuss how the simulation-based optimization generates multiple alternative shift plans, defined as …
Optimization Of Inpatient Hemodialysis Scheduling Considering Efficiency And Treatment Delays To Minimize Length Of Stay, Manuel Tolentino Peña
Optimization Of Inpatient Hemodialysis Scheduling Considering Efficiency And Treatment Delays To Minimize Length Of Stay, Manuel Tolentino Peña
Theses
Inpatient dialysis units face an uncertain daily demand of hemodialysis procedures for end-stage renal disease (ESRD) patients hospitalized for health conditions that may or may not be directly related to their renal disease. While hospitalized, these patients must receive hemodialysis in addition to any medical services needed for their primary diagnosis. As a result, when demand for inpatient dialysis is high, treatments and procedures required by these inpatients may be delayed increasing their length of stays (LOS). This research presents an optimization approach for daily scheduling of inpatient hemodialysis to maximize the efficiency of the dialysis unit while minimizing delays …
Heterogeneity-Aware And Energy-Aware Scheduling And Routing In Wireless Sensor Networks, Mahesh Kumar Vasanthu Somashekar
Heterogeneity-Aware And Energy-Aware Scheduling And Routing In Wireless Sensor Networks, Mahesh Kumar Vasanthu Somashekar
Theses
A Wireless Sensor Network (WSN) is a group of specialized transducers, called sensor nodes, with a communication infrastructure intended to monitor and record conditions at diverse locations. Since WSN applications are usually deployed in an open environment, the network is exposed to rough weather conditions, such as rain and snow. Another problem that WSN applications need to deal with is the energy constraints of sensor nodes. Both problems adversely affect the lifetime of WSN applications. A lot of research has been conducted to prolong the lifetime of WSN applications considering energy constraints of sensor nodes, but not much research has …
Simulation Analysis Of Capacity And Scheduling Methods In The Hospital Surgical Suite, Sarah Ballard
Simulation Analysis Of Capacity And Scheduling Methods In The Hospital Surgical Suite, Sarah Ballard
Theses
With health-care costs rising and an aging population, the health-care industry is progressively faced with the problem of growing demand and diminishing reimbursements. Hospital administration is often faced with a lack of quantifiable data regarding surgical suite capacity and the impact of adding new surgical procedures. With the inherent variation in surgery due to unique procedures and patients, accurately measuring maximum capacity in the surgical suite through mathematical models is difficult to do without making simplifying assumptions. Several hospitals calculate their operating room (OR) efficiencies by comparing total OR time available to total surgical time used. This metric fails to …
Efficient Job Scheduling For A Cellular Manufacturing Environment, Joshua Dennie
Efficient Job Scheduling For A Cellular Manufacturing Environment, Joshua Dennie
Theses
An important aspect of any manufacturing environment is efficient job scheduling. With an increase in manufacturing facilities focused on producing goods with a cellular manufacturing approach, the need arises to schedule jobs optimally into cells at a specific time. A mathematical model has been developed to represent a standard cellular manufacturing job scheduling problem. The model incorporates important parameters of the jobs and the cells along with other system constraints. With each job and each cell having its own distinguishing parameters, the task of scheduling jobs via integer linear programming quickly becomes very difficult and time-consuming. In fact, such a …
Faculty Scheduling Using Genetic Algorithms, Kevin Soule
Faculty Scheduling Using Genetic Algorithms, Kevin Soule
Theses
The problem of developing a class schedule for a faculty has been proven to be NP-complete. Therefore when the schedule is large enough, finding just one feasible solution can be impossible for any direct search algorithm within a reasonable time. This project is geared toward investigating the possibility of using genetic-based algorithms to solve faculty scheduling problems of 100 courses or larger quickly. Multiple versions of genetic algorithms and heuristics are tested. Many parameter levels for these algorithms are optimized for fastest convergence.

A Dynamic Web Server Based Appointment Calendar, Jane Zhong
Theses
The most advanced server side technology, Microsoft .NET Framework and Microsoft SQL, will be used to develop a dynamic web server based calendar to handle appointment and meeting scheduling. It s a new calendar in architecture and functions compared to the traditional calendars. The existing commercial calendars, such as Outlook calendar, iCal and MeetingMaker, have a common weakness: unique calendar software should be installed in the user s computer. They are all not web based calendars. Some existing web calendars, like Yahoo calendar, have very limited functions. In this proposal, a web server based calendar is proposed to overcome this …
A Dynamic Scheduling Monitor For A Manufacturing Process, Gregory Weilnau
A Dynamic Scheduling Monitor For A Manufacturing Process, Gregory Weilnau
Theses
Dynamic scheduling is the ability to create an effective schedule based on the current state of a manufacturing factory. I have developed such a scheduler for an injection molding department. The molding department provides the "factory" for which the schedule is created. In order to test my scheduling algorithm, I have developed three modules that form a complete factory model. A user interface allows access to the factory system. A factory database system permits the user to create and maintain the data that is required. The schedule and run module creates a schedule and then, simulates the schedule being run …
A Computer Simulation Of Processor Scheduling In Unix 4.2bsd, Michael D. Grossman
A Computer Simulation Of Processor Scheduling In Unix 4.2bsd, Michael D. Grossman
Theses
This project is a study of the processor scheduling system in UNIX 4.2BSD. This study involved a computer simulation of the processor scheduling system. The preliminary work for the simulation included choosing a system, choosing and running a set of test processes on that system, gathering statistics from these runs, and constructing a model of the scheduling system. The model was then tuned to perform like the real system by introducing overhead into the model. The overhead was added using several variables in the model. Tuning consisted of adjusting the values of these variables until the performance of the model …

Theses
To determine the effects of scheduling on instrumental music programs in the public school districts of Saint Louis County, Missouri, a questionnaire was distributed to fifty-two instrumental music teachers in twenty-eight districts . We proposed to find common concerns shared by instrumental music teachers with regard to the scheduling of their classes. Our respondents concurred on specific scheduling situations that cause either alteration or complete elimination of their programs. Elementary curriculum is crowded with numerous non-academic offerings which compete for student time. Missouri has recently mandated additional secondary requirements in math and science without raising fine arts credits. This has …
