A Note On Adjusting, David B. Montgomery, D.G. Morrison

Research Collection Lee Kong Chian School Of Business

Whenever a regression analysis is run, one of the key statistics which is reported is the coefficient of determination or, as it is more commonly kn R2. This quantity represents the proportion of the variance of the dependent variable that is associated with ("explained by") the set of independent vari- ables. However, this statistic is a biased estimate of the true coefficient of determination for the underlying population. Moreover, the bias in unadjusted R2 can be sizeable and may lead to serious misinterpretation of research results. The purpose of this note is to examine the magnitude of the bias in …

Bimatrix Markovian Decision Processes And Stochastic Ratio Games, Vijaykumar V. Aggarwal

Research Reports from the Department of Operations

Markov decision processes and stochastic games have been considered in this dissertation. An infinite planning horizon is assumed. Both discounted and undiscounted cash flows have been treated. In Markov decision process, a two-dimensional reward structure is considered and the objective criterion is to maximize the rate of return. It has been shown that a pure stationary optimal policy exists, whenever the rewards are finite and, in particular, the investment part of cash flow is positive. In the case of discounted cash flows, the optimal policy depends on the initial state the process is in. Finite algorithms have been proposed to …

A Decision Model Of The Countdown Process, Burton V. Dean

Research Reports from the Department of Operations

This paper examines two key decision problems in the countdown process: determining which tests and operations should be performed, and establishing their optimal sequence and duration. The authors posit that while potential actions can be enumerated at the start of the countdown, the actual sequence will depend on the system's state during the process. The paper aims to develop a methodology for solving these decision problems, viewing them as an adaptive process. Various modeling approaches are discussed, including game-theoretic models using "trees" to illustrate different countdown strategies, and search theory to find optimal action sequences. The authors also mention considering …

A National Planning Model For Higher Education, Vaughn E. Huckfeldt

Research Reports from the Department of Operations

This report presents the results of an initial research effort in the development of a national planning model for higher education. The design of the prototype model discussed in this report is based on existing or derivable (derived from basic data) institutional and student data and is designed to permit prototype planning studies to examine the impact of alternative federal programs on the accessibility of students to higher education, and to a lesser extent on the institutional viability (the ability to survive with a given level of funding). The model has assisted in identifying high payoff areas for future research …

Some Results For Hyper-Exponential And Hyper-Poisson Queues, Shailesh J. Mehta, S. Subba Rao

Research Reports from the Department of Operations

This paper examines steady-state queuing systems, focusing on hyper-exponential and hyper-Poisson queues. Explicit queue length probabilities, waiting time distributions, and related metrics are derived using an imbedded Markov chain technique for M|HE₂|1, HE₂|M|1, and M|HEₙ|1 systems. The analysis addresses stochastic service rates with multi-point distributions, providing solutions for busy period distributions in specific queuing models. A cubic equation for the Laplace transform of the busy period distribution is also presented, offering a detailed approach to understanding queue dynamics and performance metrics.

Job Satisfaction Of Police Officers In Second Class Cities In Kentucky, Joan Robertson

Masters Theses & Specialist Projects

The purpose of this study is to attempt to find out how the police officers in the second-class cities in Kentucky view their work. Questions asked concern relationships with the public, their supervisors, and co-workers; opinions of recent court rulings affecting their work; and their sentiments about salaries and plans to continue in police work. After assessing the job satisfaction of the officers, the results were correlated with other studies and recommendations are made directed toward increasing the officers' motivation and effectiveness in performing their duties.

Computational Experience With An Enumerative Algorithm For The Set Covering Problem With Base Constraints, Harvey M. Salkin, Chien-Hua Lin

Research Reports from the Department of Operations

An algorithm for the classical set-covering problem with additional "base" constraints is presented. The "base" constrained set covering problem is: Minimize cx, subject to Ex ≥ e, xj = 0 or 1 (j = 1,...,n), and Bx ≤ d. Here E is an m by n matrix of zeros and ones, e is an m column of ones, c and d are nonnegative vectors, and B is a nonnegative array having row diagonal structure. The algorithm is basically a zero-one single branch enumeration with linear programming and other feasibility criteria. A "heuristic" is used which sometimes finds an initial solution …

The Complementarity Problem Of Mathematical Programming, Arie Tamir

Research Reports from the Department of Operations

We consider the nonlinear complementarity problem: Find x in R^n such that: x ≥ 0 , f(x) ≥ 0 (1) x^T(f(x))=0 (2) where f is a given mapping satisfying f(0) = 0 and q is a vector in R^n. We say that the problem is feasible if (1) has a solution. f is said to be a Q-function if (1)-(2) has a solution for each q in R^n, and it is a P-function if the solution is unique for each q. Classes of functions are defined using properties of the complementarity problem (1)-(2), and sufficient conditions which guarantee that a …

Gochurch : A Simulation Model For Forecasting Church Growth, John J. Rasmussen

Research Reports from the Department of Operations

This paper examines the rapid growth of evangelical churches in America and introduces a simulation-based forecasting model, GOCHURCH, to aid in planning for future attendance. The model addresses the challenges faced by churches striving to meet aggressive growth targets while managing facility and program capacity. GOCHURCH predicts attendance numbers and provides structured descriptions of individuals influencing the growth process, using a Markovian framework to categorize the population into five states. A supporting questionnaire gathers data relevant to forecasting, and an initial simulation output demonstrates the model’s applicability to capacity planning. By analyzing membership trends and offering predictive insights, GOCHURCH helps …

Optimal Flows In Networks With Positive Gains, Klaus Truemper

Research Reports from the Department of Operations

Simple, yet powerful non-simplex algorithms are developed for max flow and min-cost flow problems in networks with positive gains. It is shown that these algorithms are computationally better than existing non-simplex algorithms. A strong relationship between the min-cost flow problem in pure networks and the max flow problem in networks with positive gains is used to demonstrate how algorithms for one problem can be transformed into ones for the other problem.

One Machine Sequencing To Minimize Mean Flow Time With Minimum Number Tardy, Hamilton Emmons

Research Reports from the Department of Operations

The problem of sequencing n jobs on one machine is considered, under the multiple objective of minimizing mean flow time with the minimum number of tardy jobs. A simple procedure is first proposed to schedule for minimum flow time with a specified subset of jobs on time. This is used in conjunction with Moore's Algorithm in a simple heuristic producing good and often optimal schedules. A branch-bound algorithm is presented to produce the optimal schedule efficiently with the help of several theorems which eliminate much branching.
