A Decision Support Model Using Life Cycle Cost (Lcc) Analysis To Select Cost-Effective Alternatives For Hazardous Materials, Blaine F. Burley, Kirk A. Phillips

Theses and Dissertations

This research focuses on the development of a decision support model to select cost-effective alternatives for hazardous materials using life cycle cost (LCC) analysis. The model provides an effective decision-making tool to evaluate the economic feasibility of using alternatives for hazardous materials. Given a specific operation, the users of this model can enter site-specific cost data to determine the total LCCs of using baseline hazardous materials (i.e., hazardous materials currently being used in an operation), as well as the total LCCs of using various alternatives. This thesis postulates that the material having the lowest total LCC is considered to be …

Hands-On Structural Engineering Experiences With The "Anex" Mini-Laboratory, Richard A. Behr, Colin Othniel Benjamin, Azam A. Mirza

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The ANEX facility has been developed to allow nearly real-time comparisons of analysis results with experimental data gathered on small-scale structural models. ANEX has been used successfully for in-class demonstrations, student-designed experiments, and comprehensive design/build competitions in an introductory structural analysis course at the University of Missouri-Rolla. An expert system is now being developed to guide ANEX users and to act as a trouble-shooter and advisor in the event that analytical and experimental results do not correlate acceptably well. ANEX, using only simple, small-scale model structures, is able to enrich structural engineering instruction by introducing students to the sophisticated capabilities …

Knowledge-Based Prototype For Improving Scheduling Productivity, Colin Othniel Benjamin, Daniel L. Babcock, N. B. Yunus, John B. Kincaid

Engineering Management and Systems Engineering Faculty Research & Creative Works

The development of efficient construction plans and schedules presents continuing challenges to construction schedulers. Knowledge-based systems offer considerable potential as computer-based planning tools to aid the development of realistic project plans and schedules. This paper outlines the development of a knowledge-based prototype system for construction planning and scheduling and evaluates its effectiveness as a tool for improving the productivity of inexperienced construction project schedulers. The prototype, developed using the M.1 knowledge engineering shell, incorporates data bases, algorithm, and heuristics that mimic the decision process of expert construction project schedulers and identifies a work breakdown structure and precedence relationships. Inexperienced schedulers …

Optimal Allocation Of Water Among Industries In Dar Es Salaam City, Tanzania, J. I. Matondo

Tanzania Journal of Engineering and Technology (TJET)

Dar es Salaam is the city with the largest number of industries in Tanzania. However, the water demand for these industries is more than the supply. Therefore, there is a water use competing problem among the industries. Dynamic programming technique has been applied to optimally allocate the available water among the industries with the objective of maximizing the net benefits. Results reveal that, industries with the highest net return per unit of water will get the first priority of being allocated water.

Measurement Of Air Force Fire Department Productivity: An Evaluation Of Efficiency/Effectiveness, Timothy A. Byers, Susanne M. Waylette

Theses and Dissertations

This research was sponsored to develop a method of evaluating the productivity of Air Force Fire Departments. Using the tasks developed by the Fire Department Workshop, input and output measures were defined and used in a new model of efficiency called Constrained Facet Analysis (CFA). The advantage of this methodology over others considered was that it can simultaneously evaluate multiple inputs and multiple outputs using empirical data with no a priori weighting. The results of the analysis provided an efficiency rating for each fire department and information about marginal rates of substitution and marginal rates of productivity for inefficient units …

Bulletin Ma 20 - Sheep Yard Plans - Flocks Up To 500, D. Bicknell

Animal production and livestock published reports

Manjimup Regional Office

Owners of small flocks often use much more labour per sheep than do owners of large flocks. Most of the difference in labour use is the design of sheep sheds and sheep yards, and a smaller affect from the mob size and experience in handling sheep.

This booklet gives some detail on design and construction of yards and a number of yard plans to handle up to 500 or so sheep. Many of the plans are from an Australian Wool Corporation publicatiot1 "Wool Harvesting Notes".

Computer Usage In The Construction Industry And Construction Education, Stephen Douglas Stulken

Dissertations and Theses @ UNI

The rapid growth of computer usage in American society, and in the construction industry in particular, has important implications for construction education programs. There is a lack of current information about computer usage in the construction industry. Without this information, construction educators are less likely to provide students with relevant computer competencies that relate to the needs of the construction industry.

The objective of this study was to determine to what extent construction education programs provide the necessary computer competencies for their students. This was accomplished by comparing the current status of computer usage in the construction industry with computer-related …

Lot Feeding Of Beef Cattle. 1. Introduction, W J O Wilkie

Journal of the Department of Agriculture, Western Australia, Series 4

"LOT FEEDING" of cattle is the name given to the operation of bringing cattle in from pasture and giving them the total ration they are to receive in open or partly roofed yards.

The roof would be intended to protect the feed trough and not the cattle.

Well Designed Cattle Yards, W J O Wilkie

Journal of the Department of Agriculture, Western Australia, Series 4

GOOD yards are those in which cattle can be handled quietly, safely and efficiently.

The manner of handling is as important as the design of the yards.

Too much dog or whip can make cattle difficult, in even the best of yards.

A Crush For Tuberculin Testing Of Cattle, A L. Ripper

Journal of the Department of Agriculture, Western Australia, Series 4

ALWAYS a useful asset on any farm where livestock are kept, a strongly-constructed crush is essential where tuberculin testing makes it necessary to deal with dry stock, bulls and young animals that have not been previously handled.

The crush described in this article was specially designed for tuberculin testing, but will serve equally well for vaccinating, branding, de-horning or any operation where restraint is necessary.

Let's Look At Herringbone Dairies, R A. Bettenay, F. Fielder

Journal of the Department of Agriculture, Western Australia, Series 4

THE first of the modern type herringbone dairies in Western Australia was constructed by Mr. F. Tucker of Ruabon, in 1957.

Since then there has been strong interest in this system, and there are now at least six such sheds operating in the district between Ludlow and Augusta. Many more are being constructed.

Shearing Shed Design, W L. Mcgarry, D. A. Young, M. Butler

Journal of the Department of Agriculture, Western Australia, Series 4

PLANNING the layout of a shearing shed requires a good deal of thought to ensure its maximum working efficiency.

If the contemplated structure is to serve the dual purpose of storage-shearing shed, it is better to plan a shearing shed that can be used for storage, rather than a storage shed with a view to its utilisation as a shearing shed.
