Some Efficient Dynamic Programming Algorithms For The Optimal Sequencing And Scheduling Of Water Supply Projects, Augustine O. Esogbue, Thomas L. Morin

Research Reports from the Department of Operations

The sequencing and scheduling aspects of some important capacity expansion problems encountered in water resources development are studied. Dynamic programming algorithms are developed for both project timing problems and combined project selection and timing problems involving durable high cost water supply projects, which in the aggregate are subject to continuous-time demand requirements. The structure of the problems is successfully exploited in order to produce computationally efficient algorithms to solve problems of the dimension encountered in water resources systems. The computational superiority of these algorithms over conventional dynamic programming algorithms is discussed and illustrated via a numerical example.

Parallel Operations Of Sequential Service Lines With Interline Transfer, Joseph A. Svestka, K.P. K. Nair

Research Reports from the Department of Operations

Scientific analysis of servicing processes has resulted in the development of sequential servicing where in a unit requiring service is processed through a fixed number of stages sequentially. A detailed study of such a system has been presented by Baling. In this paper a large servicing system consisting of a finite number of identical sequential service lines is considered. These lines are operated in parallel but interline transfers of units are made whenever advantageous. Using time homogeneous Markov Chain, a model is developed for analyzing the operation of such a system. It is shown that interline transfers of units result …

A Generalized Upper Bounding Method For Doubly Coupled Linear Programs, James K. Hartman, Leon S. Lasdon

Research Reports from the Department of Operations

The constraints of large linear programs can often be partitioned into independent subsets, except for relatively few coupling rows and coupling columns. The individual subsets may, for example, arise from constraints on the activity levels of subdivisions of a large corporation. Alternatively, such blocks may arise from activities in different time periods. The coupling rows may arise from limitations on shared resources or from combining the outputs of subdivisions to meet overall demands. The coupling columns arise from activities which involve different time periods (e.g storage), or which involve different subdivisions (e.g. transportation or assembly). The case with only coupling …

A Taxonomic Analysis Of Financial Ratios, Denis Moffet

Research Reports from the Department of Operations

Operations research techniques have been applied in fields like portfolio management, inventory control, and capital budgeting, but their use in accounting remains underdeveloped. This paper seeks to undertake a taxonomic analysis of financial ratios by developing a formal system for classifying the most commonly used financial ratios, identifying the most important dimensions measured within that set of ratios, and determining the relative importance of each ratio in measuring each dimension.

Measurement Of Output In A System Of Social Agencies, Arnold Reisman, Samuel J. Mantel Jr., Burton V. Dean, Norman C. Eisenberg, Elliot Markus, Allan L. Service

Research Reports from the Department of Operations

An on-going research project being performed at the Jewish Community Federation of Cleveland is described. Background of the project is given. The basis and components of a proposed output measurement mechanism are discussed briefly so that the details of implementing that measurement model may be considered in perspective. Three aspects of the implementation process are examined: the generation of service-client package values, the development of quality criteria weights and utility curves, and the collection of the requisite objective data. In each case, an objective is defined, the conceptual and mechanical details of the implementation process are given, and the results …

Some Manpower Planning Models Based On Educational Attainment, Warren L. Balinsky

Research Reports from the Department of Operations

This paper is concerned with analytical solutions to manpower planning models. Dynamic feed-forward models are developed and analyzed. Optimal closed-form solutions minimizing given objective functions for the above models are developed. The models considered treat people as the only flow variable. The flow originates with some particular population of eligible persons and then traces them through the educational and economic sectors of the model. An objective function is developed, composed of educational costs and manpower "inventory" or penalty costs. The educational costs are for teacher and administrative salaries, investment in buildings and grounds, etc. The manpower penalty costs are for …

A Generalized Upper Bounding Algorithm For Multicommodity Network Flow Problems, James K. Hartman, Leon S. Lasdon

Research Reports from the Department of Operations

An algorithm for solving min cost or max flow multicommodity flow problems is described. It is a specialization of the simplex method, which takes advantage of the special structure of the multicommodity problem. The only non-graph or non-additive operations in a cycle involve the inverse of a working basis, whose dimension is the number of currently saturated arcs. Efficient relations for updating this inverse are derived.

Modeling And Simulation Of Urban Transportation Systems: A Survey, Juri Pill

Research Reports from the Department of Operations

This paper is essentially a survey of traffic network modeling techniques used in transportation studies and planning, a broad field with voluminous literature. It does not pretend to be exhaustive, but most of the relevant work is discussed, and an attempt is made to delineate an apparent trend in research approaches. Transportation research has grown in the past decade to the point where new journals have sprung up and funding is available; the problems of people movement are certainly not highest on the scale of current priorities, but improvements are in order. As with most other issues, transportation cannot be …

Deterministic And Stochastic R & D Resource Allocation Models, Donald C. Friedel

Research Reports from the Department of Operations

The primary concern of this dissertation is R&D resource allocation. Although the discussions are directed toward allocating resources to R&D projects, the techniques developed may be applied to any type of project whose characteristics comply with the assumptions imposed upon the models. Since resource allocations to projects are obtained indirectly from the scheduling of the projects, project scheduling plays a significant role in this paper. Project selection, a third problem of concern to R&D management, is also considered, to a lesser extent, throughout the thesis. Projects are assumed to consist of phases that are arranged either in a network fashion …

Analysis Of The Exploratory Development Project Evaluation Experiment, Burton V. Dean, Samuel Jackson Mathis, Benjamin Lev, Joseph A. Svestka, Mauricio Adler

Research Reports from the Department of Operations

This paper details an exploratory development project evaluation (EDPE) experiment aimed at developing and testing a method to obtain quantitative data using subjective judgments for evaluating research and development (R&D) projects. The experiment, conducted at the U.S. Army Materiel Command, utilized a modified DELPHI Method involving a panel of twelve members. Key findings include the panelists’ ability to reach consensus in two rounds, the sufficiency of a small number of factors for linear model formulation, and the absence of significant bias. The results suggest potential for further experimentation to validate the EDPE method’s predictive capability.

A Model For The Development Of Measures Of Effectiveness In Airlift Planning, Alexander Brandt

Research Reports from the Department of Operations

A mathematical model of a military airlift problem is formulated. The model includes an algorithm for the solution of the Traveling Salesman problem. The model's solution is utilized in the allocation of aircraft to routes so that the cost of an airlift operation is minimized. A procedure for finding the optimum solution to the Traveling Salesman problem is programmed for the UNIVAC - 1108 digital computer using the FORTRAN language. The computer program was given preliminary testing on 3 digit random number distance matrices and was shown to be operationally practical and economical. For illustrative purposes an example is presented …

Automated Information Retrieval Systems For Legal Research, Robert G. Baylor

Dissertations and Theses

Purpose. This study of automated information retrieval systems was undertaken to attempt to ascertain the extent and development of a total legal information system.

Overview. Historically, lawyers have searched the statutes and case law in the traditionally manual method. Given consistent high standards of editing, not too complex materials, and a collection of manageable size, this manual method will work to reasonable satisfaction, so long as a document never changes in meaning or significance. Lawyers point out that the present manual system is inadequate because with 30,000 new judicial decisions and 15,000 new statutes being promulgated each year …

A Theory Of Formal Organization And Its Acceptance By The Business Practitioner, Edgar Thomas Busch

Graduate Theses and Dissertations

Formal organization theory has evolved from the traditional school of thought through the scientific management and behavioral schools and into what is currently called open system theory. In spite of voluminous writing by the academician, no school of thought or no theory has been universally accepted. This may be due to the failure to consult the businessman who interprets and applies theoretical concepts to the practical situation. The purpose of this study was to help clear the theory jungle by determining the extent to which a sample of business practitioners agreed with basic factors of a comprehensive theory of formal …

Curriculums In The Operations Research Department At Case Western Reserve University, Patrice Breining

Research Reports from the Department of Operations

The courses within the Operations Research Department were classified into one of four major fields (i.e., Optimization Theory, Stochastic Systems Behavior, Information Processing, and Research and Development). Courses within a field must usually be taken in a pre-defined order. However, since those in different categories are almost independent, and those in Research and Development (R&D) do not usually require specific prerequisites, one can consider three independent oriented networks. These are used to design the average schedule which draws from each course category. The programs of study of 50 randomly selected students registered in the Department between Fall 1967 and Fall …
