Software Quality Assurance, Edward C. Soistman
Software Quality Assurance, Edward C. Soistman
Retrospective Theses and Dissertations
The problems associated with software development and use are investigated from a management point of view. Having identified the critical aspects of effective software management, an approach is suggested for the creation and implementation of a software quality assurance program, Particular attention is focused on the concept of Life Cycle Procurement as currently utilized by the Department of Defense. The research was accomplished in two phases. The first consisted of an extensive literature search, seminar attendance and participation in several working groups assigned the responsibility for establishing software quality assurance guidelines. The second phase involved direct participation in the development …
Energy Resource Allocation Optimization: A Mixed Integer Programming Fixed Charge Model, Mashaallah Khorsandi
Energy Resource Allocation Optimization: A Mixed Integer Programming Fixed Charge Model, Mashaallah Khorsandi
Retrospective Theses and Dissertations
A fixed charge model has been developed for a case study of a total energy power plant involving energy demands for chilled water, high temperature hot water, and electrical power. Using a FORTRAN computer program, which employs the Land and Doig branch and bound algorithm, the system model is solved for different sets of system demands for multiple energy users, and the following set of information is obtained to guide the decisions of operations personnel: 1. Recommend on/off status for each piece of equipment in the system. 2. Recommended rate of operation for each piece of machinery. 3. Required amounts …
Energy Resource Allocation Optimization--A Linear Programming Model, Paul F. Hutchins
Energy Resource Allocation Optimization--A Linear Programming Model, Paul F. Hutchins
Retrospective Theses and Dissertations
A linear programming model has been developed for a Central Energy Plant which minimizes operational costs for a system involving the generation of chilled water and high temperature hot water plus the generation and/or purchase of electric power with equipment using natural gas or fuel oil energy. The fundamental concepts developed herein are sufficient for the analysis of any combination of energy supplies, demands, and energy conversion equipment. Utilization of this model is demonstrated with a case study and computer program results for high and low temperature environments. The linear programming model approach establishes a well-defined framework for the analysis …
