High Performance Queueing And Scheduling In Support Of Multicasting In Input-Queued Switches, Weiying Zhu
High Performance Queueing And Scheduling In Support Of Multicasting In Input-Queued Switches, Weiying Zhu
Electrical & Computer Engineering Theses & Dissertations
Due to its mild requirement on the bandwidth of switching fabric and internal memory, the input-queued architecture is a practical solution for today's very high-speed switches. One of the notoriously difficult problems in the design of input-queued switches with very high link rates is the high performance queueing and scheduling of multicast traffic. This dissertation focuses on proposing novel solutions for this problem. The design challenge stems from the nature of multicast traffic, i.e., a multicast packet typically has multiple destinations. On the one hand, this nature makes queueing and scheduling of multicast traffic much more difficult than that of …
Use And Effectiveness Of Contract Schedule Incentives In Air Force Materiel Command, Rodrick A. Koch
Use And Effectiveness Of Contract Schedule Incentives In Air Force Materiel Command, Rodrick A. Koch
Theses and Dissertations
Are contract schedule incentives utilized by our acquisition contracting workforce, and if so what are their effectiveness? This research shows there is not widespread use of these types of incentives. There is also disagreement on their perceived effectiveness. Surveying, via email, the population of contracting officers and buyers within Air Force Materiel Command yielded responses from every center and many large acquisition systems. Only 8.5% of responses showed that they use schedule incentives. These respondents claim that schedule incentives are somewhat effective, yet of the 91.5 % that have not used them, 2-to-l say they would not be effective. The …
Data Analysis And Its Impact On Predicting Schedule & Cost Risk, Steven M. Cross
Data Analysis And Its Impact On Predicting Schedule & Cost Risk, Steven M. Cross
Theses and Dissertations
Many databases rely on documents (research) of the past to input data to create a comprehensive database. The Selected Acquisition Report (SAR) is one such document. The SARs are pervasive documents that have undergone decades of scrutiny by Congress and watchdog organizations such as the Government Accountability Office. Since the SAR has undergone such massive evolutionary changes, creating an accurate acquisition database presents a daunting task for the analyst and researcher alike. This research concerns itself with one such database. From this prior research database, we look to fill in missing data. We first conduct a literature review to determine …
Improving Intercontinental Ballistic Missile Maintenance Scheduling Through The Use Of Location Analysis Methodologies, Dale L. Overholts Ii
Improving Intercontinental Ballistic Missile Maintenance Scheduling Through The Use Of Location Analysis Methodologies, Dale L. Overholts Ii
Theses and Dissertations
The events of September 11, 2001 have led to increased security requirements for all ICBM-related activities. Missile maintenance managers must explore new scheduling techniques to sustain weapon system readiness levels in light of published security enhancements. The problem of improving missile maintenance scheduling is modeled as a two-stage heuristic that utilizes the maximal covering location problem methodology. Maintenance activities are categorized and weighted according to published priority designation and mission impact. The model’s first stage seeks to select two security umbrellas that maximize the weighted sum of maintenance activities. Stage two seeks to determine a maintenance schedule comprised of launch …
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 Robust Reactive Scheduling System With Application To Parallel Machine Scheduling, Jean-Paul M. Arnaout
A Robust Reactive Scheduling System With Application To Parallel Machine Scheduling, Jean-Paul M. Arnaout
Engineering Management & Systems Engineering Theses & Dissertations
In this turbulent world, scheduling role has become crucial in most manufacturing production, and service systems. It allows the allocation of limited resources to activities with the objective of optimizing one performance measure or more. Resources may be machines in a factory, operating rooms in a hospital, or employees in a company, while activities can be jobs in a manufacturing plant, surgeries in a hospital, or paper work in a company. The goal of each schedule is to optimize some performance measures, which could be the minimization of the schedule makespan, the jobs' completion times, jobs' earliness and tardiness, among …
A Dynamic Web Server Based Appointment Calendar, Jane Zhong
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 …
