Application of Statistical Distribution Theory to Launch-on-Time for Space Construction Logistic Support
The Center for Space Construction (CSC) has acquired historical launch vehicle data for analyzing space launch vehicle logistic support of space construction. This analysis will include...
DYCAM: A Computer Aided Engineering Tool for Space Construction Planning
Planning and management of construction activities in space have not received sufficient attention up to the present. Space Station Freedom, a number of large platforms and extraterrestrial...
The Selection of Constructors for Space Construction
The process of space construction is defined by the construction goal and by the construction system selected to accomplish that goal. The goal provides the tasks that must be executed,...
A Language Model for Space Construction Control
The optimal construction system for many space construction projects is a mixed construction ensemble. Such an ensemble consists of humans, robots with varying degrees of teleoperation...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
Alternatives for the U.S. Manned Space Program
There are a number of directions the U.S. space program could take. Should a space station be built? Should a lunar outpost be constructed? Should the U.S. plan a manned trip to Mars?...
Evaluation Plus History Equals Sewer Renovation
Sewers built in the 1920's were overflowing in the Fort Worth Zoo after moderate rain events. Data from A Sanitary Sewer Evaluation Survey (SSES), plus the Maintenance History...
Creatively Cost Sharing a Large Flood Control Dam
The passage of Public Law 99-662 in November of 1986, commonly known as the Water Resources Development Act of 1986, added a new dimension to Federal development of water resource projects....
Rehabilitation Model for Water Distribution Systems
This paper presents an optimization model for determining the minimum cost rehabilitation and replacement of pipes in water distribution systems. The advantages of the proposed model include...
Balancing Needs: Growth & Infrastructure Rehabilitation
Long range planning must include more than construction of facilities to meet new demands for service. A conscious effort must be made to balance the need for additional facilities with...
Cost-Effective Maintenance and Replacement Scheduling
The paper discusses operations research approaches to scheduling maintenance on components of water resources infrastructure. Cost and reliability objectives are explicitly considered....
Models for Optimal Maintenance of Hydraulic Structures
Corrective maintenance includes the unscheduled repairs required to return a structure from a failed state to an operating or available state. Corrective maintenance is determined by the...
Economic Assessment of Infrastructural Development for the Gurara River in Nigeria
Based on the preliminary designs of the hydraulic structures for the proposed Gurara river water development project in Nigeria, an economic feasibility analysis is presented. The cost...
Financing Small Water Supply Projects in Colorado
In order to meet the water supply needs of Colorado communities and the requirements of the Safe Drinking Water Act of 1986, the Colorado Water Resources and Power Development Authority...
Key Environmental Development Issues
Those in the business community who may be affected by environmental factors include: buyers and sellers of businesses, existing facilities, and real property; their lenders, brokers,...
Appropriate Cost Factors for System Reliability
This paper examines the development of appropriate costs to be associated with various levels of failure of water distribution networks and water supply systems. A clear distinction is...
Environmental Permitting a Major Expressway Facility in Florida
As general consultant to the Tampa-Hillsborough County Expressway Authority, Howard, Needles, Tammen and Bergendoff (HNTB) was responsible for the environmental permitting required for...
Weighting Factors for Transferable Discharge Permit Programs That Group Several Pollutants
Transferable discharge permit (TDP) programs for controlling several pollutants may manage such pollutants as several individual commodities or as a single weighted sum of the various...
Real-Time Optimized Control of a Water Distribution System
The paper presents the design of a fully automated real-time computer control scheme for least cost operation of a water distribution system. The scheme includes modules for optimized...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
