Approaches for solving some scheduling and routing problems
No full textWe study approaches for finding good solutions, and lower bounds, for three difficult combinatorial optimisation problems.The supply ship travelling salesman problem is a simplification of a situation faced by a naval logistics coordinator who must direct a support vessel tasked with resupplying ships in a fleet. It is a generalisation of the travelling salesman problem in which the nodes are in motion, each following some predetermined route. We apply dynamic programming state-space relaxation
techniques, producing lower bounds for the problem that are 73% to 84% of the best solution, on average. We also apply heuristics to find good solutions to this NP-hard problem, showing that restricted dynamic programming approaches outperform simple 2-opt and 3-opt local search procedures
for instances with 20 nodes.We introduce the supply ship scheduling problem, another roblem inspired by a support vessel environment. We wish to minimise the number of mobile machines required to process a set of jobs; each job is in a different stationary location and features a fixed start time. Jobs may be simultaneously processed by multiple machines, obtaining a speed-up in processing time. We represent the problem as a directed graph and use the minimum flow in a transformed network to determine the minimum number of machines. We present a neighbourhood structure based on the maximum cut, applying it
within descent and tabu search procedures. We construct a restricted dynamic programming based approach, but this is outperformed by the tabu search algorithm.The task allocation problem, arising in distributed computing, is to assign a set of tasks to a set of processors so that the overall cost is minimised. Costs are incurred from processor usage, interprocessor communication and task execution. We construct, and try to improve, semidefinite programming relaxations to find lower bounds for variants of this NP-hard problem. We develop a branch-and-bound approach to find optimal solutions, but this is only effective for small instances
The Origins and Development of the Indian Removal Policy
No full text158 leaves.The problem. The purpose of this work is to present a descriptive narrative of the men, problems and events which made up American Indian policy from 1800 to 1840. A primary objective is to trace the origins and mark the major developments of the Federal Government's policy of removing Indian tribes to the western side of the Mississippi River. Andrew Jackson's role in these developments will be stressed.
Procedure. After a brief review of pre-Jeffersonian Indian policy, the thesis traces the events which led from the formulation of the removal concept at the beginning of
the 19th century to its final culmination in the late 1830's. By combining primary sources such as government documents and
collected correspondence with recent secondary books and articles, the thesis focuses on the formulation of removal and not the actual removal operations.
Findings. The study finds that while removal was considered prior to the War of 1812, it was not until Indian military power east of the Mississippi was broken in that conflict, that removal came to be seen as the final
solution to the Indian "problem" in the 1820's. James Monroe, John C. Calhoun and other federal leaders actually defined the policy which Andrew Jackson implemented. Jackson used
this foundation, supported states' rights and allowed Congress to provide the necessary legislation for removal
Attitudes Toward Women as Administrators in the Des Moines, Iowa Public Schools
No full text113 leaves. Advisor: Dr. Richard LampshireThe problem. In a profession dominated in numbers by women, few women find their way to the top. There are relatively few women in positions of leadership or administration in education. The purpose of this study was to determine the attitudes of the school related community toward women as administrators in the Des Moines, Iowa public schools.
Procedure. Five segments of the Des Moines community were the population for this study. Sample groups were taken from: (1) students in fourth, eighth, and eleventh grades;
(2) parents of children in these grades; (3) teaching faculty from the schools attended by these students; (4) present administrators in these buildings; (5) personnel from the College of Education, Drake University. Sample groups were given an opinionnaire prepared by the author and consisting of twelve statements which describe tasks, roles or characteristics of administrators. Results were tabulated and the data analyzed. Textual summaries and tables appear in numerical and percentage form for ease of interpretation.
Findings. The study shows that men and women are considered equally able at public relations, at having ambition and a career commitment, at having insight into the needs of people. Women are perceived as working as well under women as under men, as being able to satisfy the community in assuming principalship of a school. Men and women are viewed as being equally able to make decisions and to organize effectively. Males are believed to be better disciplinarians by parents, students and older teachers, not, however, by the majority of the teaching faculty nor by administrators. Women are considered to be more sensitive, taking things more personally than men. Most segments of the study believed that young girls need successful women as models to emulate, and most segments also do not perceive the Des Moines schools as having a particular problem of sex bias or discrimination.
Conclusion. The findings of this study, when viewed as a whole, do not show any consistent negative attitudes toward women as administrators in the Des Moines, Iowa public Schools. On most of the questions asked, men and women were regarded by the subjects as equally able to perform tasks of leedership
