Transportation Cask Life Cycle Cost Uncertainty Analysis
This paper demonstrates an uncertainty analysis methodology using random sampling. This methodology has been applied to a nuclear waste transportation code, and several transportation...

Analysis of RADTRAN Transportation Model
The RADTRAN computer model, used to estimate the risks of transporting waste to a high-level repository, is critically reviewed. Ignoring high consequence accidents, human error, sabotage,...

The Systems Integration Modeling System
The Systems Integration Modeling System (SIMS) is an analysis tool for the detailed evaluation of the structure and related performance of the Federal Waste Management System (FWMS) and...

A Systems Engineering Cost Analysis Capability for Use in Assessing Nuclear Waste Management System Cost Performance
The System Engineering Cost Analysis (SECA) capability has been developed by the System Integration Branch of the U.S. Department of Energy's Office of Civilian Radioactive...

Designed Experiments: An Interdisciplinary Approach to Space Education
The challenge of space is forcing engineering faculties to re-examine their roles in preparing college graduates to contribute to the space exploration and colonization effort. One of...

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...

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...

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...

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...

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...

Marginal Cost Techniques for Reservoir Optimization
Selection of the optimum water supply reservoir from multiple reservoir sites under consideration in a water resource planning study for the Houston Metroplex evaluated hydrology, engineering,...

Benefits from Floodplain Management Activities in Relation to Operating South Holston Dam
Floodplain management activities have primarily been directed toward avoiding floodplain siting where practical; where siting is unavoidable, elevating structures, facilities, or equipment...

Successful Siting Incentives
Citizen opposition to the siting of facilities that store, produce or use hazardous materials is both widespread and problematic. There are siting incentives that have worked to allay...

Buried Treasure
Kelly describes landfill mining feasibility studies at two New England communities. Recently, due to rising landfill closure costs, a concept of landfill mining has been tested and shown...

Choosing Display Hardware for Transportation Planning Packages
This paper reviews the popular transportation planning software packages on the market and their graphics capabilities. Hardware options that allow the user tp achieve high resolution...

A Graphical Database for Transportation Systems
A graphical database composed of programmable objects analogous to elements of a physical plant of a transportation network is presented. The discussion reviews the application of a graphical...
