Application Of Fuzzy Set Technique To Agricultural Planning, S Kumar, Narasingh Misra, B C Ghosh

IIMB Management Review

In India, agriculture remains the dominant sector of economic activity with 74 percent work force depending on it. But the share of income from agriculture sector is less than the employment in it. Also the menace of unemployment and food requirement is increasing with growing population. Hence , there is a great need for increasing production and net profit levels on one hand and employment generation on the other. Irrigation planning plays an .mportant role in increasing agricultural production, net benefit, employment generation etc. as only 32 percent of the total cultivated area is irrigated in our country. Irrigation Planning …

Development And Validation Of A Model For Training Maintenance Supervisors For Productivity Improvements In Manufacturing Operations, Robert Reed Johnson

Dissertations and Theses @ UNI

The problem of this study was to develop and validate a training model for training maintenance supervisors. This training model focused on those areas, defined by industrial managers, where additional supervisory training was most likely to improve the performance of the maintenance departments.

Research of industrial and maintenance publications identified the maintenance function as having one of the lowest productivity levels in manufacturing organizations. Supervisor training was identified as a means to improve productivity in maintenance departments. An industrial survey completed by maintenance managers in manufacturing organizations in Iowa, Illinois, Minnesota, and Wisconsin identified those activities that were the responsibility …

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".

An Introduction To The Winograd Discrete Fourier Transform, Janice S. Agnello

Retrospective Theses and Dissertations

This paper illustrates Winograd's approach to computing the Discrete Fourier Transform (DFT). This new approach changes the DFT into a cyclic convolution of 2 sequences, and illustrates shortcuts for computing this cyclic convolution. This method is known to reduce the number of multiplies required to about 20% less than the number of multiplies used by the techniques of the Fast Fourier Transform. Three approaches are discussed, one for prime numbers, one for products of primes, and lastly one for powers of odd primes. For powers of 2 Winograd's algorithm is, in general, inefficient and best if it is not used. …

Methods And Techniques Used For Job Shop Scheduling, Yoo Baik Yang

Retrospective Theses and Dissertations

The job shop scheduling problem, in which we must determine the order or sequence for processing a set of jobs through several machines in an optimum manner, has received considerable attention. In this paper a number of the methods and techniques are reviewed and an attempt to categorize them according to their appropriateness for effective use in job shop scheduling has been made. Approaches are classified in two categories: a) analytical techniques and b) graphical methods. Also, it should be noticed that this report does not include all the attempts and trials, especially the heuristic approaches.
