The Mystery Of Linear Programming Explained: Second Edition, Jack Yurkiewicz

Faculty Working Papers

Sir Arthur Conan Doyle's Sherlock Holmes explains to Watson and the reader how to use Solver, an application of Excel used to solve mathematical programming problems. Holmes walks his audience through modeling the problem in Excel, using Solver to get the optimal solution, a description of variables, a discussion of shadow prices and right-hand sensitivity analysis, and an explanation of reduced costs.

A Comparison Of Public Agency And Casino Employee Turnover Rates In Las Vegas, Timothy A. Clemens

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary focus of this professional paper is to determine and then compare turnover rates between public agencies and the gaming industry in the Las Vegas area. The paper's intention is to discover what differences and similarities in employee turnover rates exist between public agencies and casinos. A secondary focus is to determine if the public sector can provide any lessons to lower employee turnover to the Las Vegas gaming industry. This secondary focus is based on the assumption that public agencies have higher employee retention (and, therefore, a lower rate of turnover) than those found within the Las Vegas …

Introduction: Are We Requiring What Our Students Most Need?, Michael Alan Netzley

Research Collection School of Social Sciences

Why devote a special issue to the topic of writing requirements for business students?The answer, I believe, is relatively simple: any such requirement mustreflect what business professionals should know and do in a knowledge economy.Because communication practices are changing radically, our requirements, too,must be reexamined. This issue provides a forum for such reexamination.

When Is Command-And-Control Efficient? Institutions, Technology And The Comparative Efficiency Of Alternative Regulatory Regimes For Environmental Protection, Peter Z. Grossman, Daniel H. Cole

Scholarship and Professional Work - Business

The nominal efficiency of a regulatory regime is determined by comparing its social costs and benefits; the regime is nominally efficient if it produces benefits in excess of its costs. Thus, a regulatory regime can be at once nominally efficient and relatively inefficient. A regulatory regime that is nominally efficient in the early days of pollution-control efforts, when increments of environmental quality are relatively cheap, may (but will not necessarily) grow less efficient over time - producing less return on each dollar invested - as increments of environmental quality grow increasingly expensive. A regulatory regime that is more efficient in …

Road Rescue Implements A Continuous Process Improvement Framework, John Olson, Paul Savory

Department of Industrial and Management Systems Engineering: Faculty Publications

Continuous improvement programs traditionally focus on making small incremental improvements to a system. Unfortunately, their success can be limited due to the rapid changing environment within which most small companies operate. Improvement efforts should be flexible enough to capitalize on incremental and radical changes to a system. This paper presents a case analysis of how Road Rescue, an ambulance manufacturer, uses a continuous improvement framework to capitalize on both radical and incremental improvement opportunities. Results include a 10% increase in throughput, reduced cycle time of 44%, increased customer satisfaction, and higher quality.

Commissioners Annuity Reserve Valuation Method (Carvm), Keith P. Sharp

Journal of Actuarial Practice (1993-2006)

This paper describes the commissioners annuity reserve valuation method (CARVM) and highlights the fundamental contrast with insurance valuation. Numerical examples illustrate methods of applying CARVM to particular annuity designs. The application of NAIC Actuarial Guideline 13 on bailouts is given particular attention.

Credibility Calculations Using Analysis Of Variance Computer Routines, Dennis H. Tolley, Michael D. Nielsen, Robert Bachler

Journal of Actuarial Practice (1993-2006)

In this paper we present a method of calculating Buhlmann-Straub credibility factors using standard statistical techniques developed for the analysis of variance. Emphasis is placed on using readily available statistical packages such as SAS and SPSS. Additionally many other computational tools such as EXCEL can be programmed to make such calculations. An example and some sample SAS programs are provided.

A Fuzzy Approach To Grouping By Policyholder Age In General Insurance, Richard J. Verrall, Yakoub H. Yakoubov

Journal of Actuarial Practice (1993-2006)

In general insurance, policyholder age is often treated as a factor with the number of levels requiring that the individual ages of the policyholders be grouped. Although the groups are usually defined by the existing underwriting structure, it should be investigated as part of any premium rating exercise that uses a model to assess past claims experience. It is possible that an incorrect grouping by policyholder age could bias the results of the risk premium estimation. On the other hand, it may not be computationally feasible to use separate ages in the premium model, making some form of grouping necessary. …

Airline Overbooking In The Multi-Class Case, Joseph Coughlan

Articles

This paper presents an airline overbooking model at a class level for one servcie compartment-cabin. Class level demand data i sused to determine the number of bookings that can be taken for each class. The model is optimised through the use of mulit-dimentsional search routines. The control level model developed is tested with data supplied by Ireland's national airline, Aer Lingus. The model shows a significant improvement over previous methods employed by Aer Lingus and was subsequently adopted by the airline.

Multilife Premium Calculation With Dependent Future Lifetimes, Michel Denuit, Anne Cornet

Journal of Actuarial Practice (1993-2006)

Actuaries traditionally have calculated multi-life (joint life) premiums by assuming the independence of the future lifetimes of insured persons. Recent studies, however, demonstrate dependence of the future lifetimes of couples (such as husbands and wives). This dependence materially affects the values of multi-life annuities and insurances. Using the Frechet-Hoeffding bounds and Norberg's Markov model, we determine the effect of this dependence in lifetimes on the actuarial present values of a widow's pension benefit.

A Study Note On The Actuarial Evaluation Of Premium Liabilities, Claudette Cantin, Philippe Trahan

Journal of Actuarial Practice (1993-2006)

Several approaches have been used to estimate premium liabilities. The emphasis of these approaches has been on unearned premium and deferred policy acquisition expenses (DPAE), as such items represent the largest components of premium liabilities. The purpose of this paper is to provide a framework for the evaluation of premium liabilities and to augment the actuarial literature. We define and review the individual components of premium liabilities as well as the regulatory requirements and Canadian Institute of Actuaries recommendations and standards of practices related to premium liabilities. We also present an actuarial approach for estimating equity in the unearned premium, …

Carvm And Naic Actuarial Guidelines 33 & 34, Keith P. Sharp

Journal of Actuarial Practice (1993-2006)

Annuity valuation under the NAIC Standard Valuation Law is determined according to methods different from those methods used for life insurance. The CARVM assumption of efficient policyholder selection is clarified under NAIC Actuarial Guidelines 33 and 34 to allow for non-elective (e.g., death) benefits. In particular, Actuarial Guideline 34 is oriented toward variable annuities and prescribes methods to be used in the presence of a minimum guaranteed death benefit. In this paper these methods are examined and illustrated with examples.

Recognizing Actuarial Assumptions, Victoria Stachowski, Alice Underwood

Journal of Actuarial Practice (1993-2006)

As assumptions underlie every aspect of actuarial calculations, actuaries must be aware of the assumptions they are using and understand their importance and the possible effects of changing assumptions on the results of their calculations. This paper explores the nature of assumptions in: (i) mathematical models, (ii) data selection, (iii) actuarial methods, and (iv) the business environment. We examine reasons for making assumptions such as convenience, tradition, indications in the data, or lack of data. In addition, we discuss (i) how actuaries can judge whether these reasons are sufficient; (ii) methods that can help actuaries quantify the impact of their …

Determination Of Optimal Premiums As A Constrained Optimization Problem, Farrokh Guiahi

Journal of Actuarial Practice (1993-2006)

A simple stochastic model of an insurer's underwriting and related investment operations is used to determine the optimal amounts of written premiums for one period for the insurer's book of business. The written premium for each class is determined by the solution of a constrained optimization problem. The insurer's objective function is the expected profit on a book of business over the period. The insurer has a safety constraint where a certain portion of capital and surplus can be depleted with a small probability. This paper provides an explicit solution for optimum expected profit and corresponding written premiums by classes. …

Reinforce For Performance: The Need To Go Beyond Pay And Even Rewards, Fred Luthans, Alexander D. Stajkovic

Department of Management: Faculty Publications

Perhaps the most talked about, if not actually implemented. practical solution for making human resources more productive is pay for performance. Yet many researchers and practitioners doubt the true effectiveness of this approach. To help solve this controversy. we suggest drawing from reinforcement theory and behavioral management. This approach can be used to explain the simple statements: You get what you reinforce. but you do not necessarily get what you pay for. We first critically review the traditional pay for performance practices and address the question of whether rewards. not reinforcers. do more harm than good. Next, we discuss the …

Linking It Applications With Manufacturing Strategy: An Intelligent Decision Support System Approach, Ravi Kathuria, Murugan Anandarajan, Magid Igbaria

Business Faculty Articles and Research

Research has indicated the importance of matching Information Technology (IT) applications or manufacturing systems with the competitive strategy of a company. Selection of the right type of IT application is, however, a challenging task. When a company, with a given dominant process structure, emphasizes two or more competitive priorities, such as quality, product flexibility, etc., an unaided manager faces a complex decision problem in choosing from alternative IT applications available in the areas of product design through distribution. In this paper, we developed an Intelligent Decision Support System (IDSS) that would assist managers with: assessment of the relative importance of …
