The Covariance Function Of The Virtual Waiting-Time Process In An M/G/1 Queue, Teunis J. Ott

Research Reports from the Department of Operations

Let R(t) be the covariance function of the stationary virtual waiting-time process of a stable M|G|1 queue. It is proven that if R(t) exists, i.e., if the service-times have a finite third movement, then R(t) is positive and convex on [0,∞), with an absolutely continuous derivative R' and a bounded, non-negative second derivative R". Also, lim R(t) = 0 and R" can not be chosen monotone. Contrary to a finding by Beneš (1957) it is proven that ∫₀^∞ R(t) dt < ∞ if and only if the service-times have a finite fourth moment.

Scheduling Intermittently Arriving Jobs To Minimize The Weighted Number Tardy, Keki R. Dadachanji

Research Reports from the Department of Operations

The problem of scheduling n jobs on one machine to minimize the weighted number tardy is considered, when job arrival times, processing times, due dates and weights are given constants. It is assumed that jobs may be interrupted at any time, and later resumed without penalty. A taxonomy of special cases for this problem is developed. Polynomial-bounded algorithms are given for some of the special cases and some other special cases are shown to belong to the set of NP-complete problems. A branch-bound solution is presented for the case in which all jobs have the same weight. The algorithm is …

Optimal Design Of Networks With Node Weighted Functions, Shailesh J. Mehta

Research Reports from the Department of Operations

The design of optimal networks on a set of points is an interesting and important problem. However, the majority of work done so far is in flow problems and on graphs with arc weights. In this dissertation, the problem of constructing optimal networks with node weights is considered. The objective function depends on the weights assigned to the nodes and the degree of the nodes. Special cases of the general design problem of constructing networks or graphs with node weights and arc weights are also treated. The intent of the research was to develop polynomially bounded algorithms. The general design …

Economic Lot Size Determination In Multi-Item, Multi-Level Production-Inventory Systems With Acyclic Network Structures, Phiroz P. Darukhanavala

Research Reports from the Department of Operations

The research presented here is oriented toward a company organized as a multi-level, production-inventory system, which can be represented by an acyclic network structure. In our model, we consider dependent stochastic demand and incorporate the concept of service level along with the associated costs of carrying safety stocks at different levels of the manufacturing chain. We develop and test an algorithm that specifically derives the dependent demand distributions and then computes optimal order quantities based on a trade-off between setup, holding, and safety stock costs at all levels. The algorithm, which is iterative in nature, can be easily incorporated into …

Antipollution Activities In Input-Output Analysis: An Application To Water Quality Management, Kwang-Soo Lee

Research Reports from the Department of Operations

This thesis is concerned with the following problems involved in the analysis of economic systems with antipollution activities: (i) a mathematical formulation of the problem of determining their equilibrium, (ii) a solution technique for this model, (iii) approximation of interregional transaction figures, and (iv) the formulation of a general model for water quality management of a watershed basin economy. Extending the Leontief input-output model, an economic system with pollution abatement activities is formulated as a complementarity problem with upper bounding constraints. The complementarity problems for M-matrices are studied, and it is shown that the model is always feasible and that …

Corporate Tax Structures And A Special Class Of Set Partitioning Problems, Chien-Hua Lin

Research Reports from the Department of Operations

This thesis discusses a special integer program, a complete set partitioning problem in context of a real world situation; namely, that of paying unemployment compensation tax. In the United States, employers are required to pay contribution to a state administered unemployment compensation fund to protect the employees in the event of unemployment. A corporation can often be considered as a composition of subsidiaries, each with their own accounting data. In many states including Ohio, these subsidiaries may be treated individually or in various aggregations, each aggregation becoming a subsidiary, prior to computing the contribution payment. The payment is a function …

Optimal Rearrangement Of Objects, Ashok Kumar Mittal

Research Reports from the Department of Operations

This dissertation deals with finding an optimal way of changing a given arrangement to a (specified) new arrangement. Two types of problems are considered. In the first type of problem, there is no extra storage space available for storage of the objects. The rearrangement is done by a sequence of pairwise exchanges. In the second type of problem there is extra storage space available for storage. The rearrangement in this case is done by a vehicle which moves one object at a time. Problems are further classified by type of arrangement as basic cycles, cycles--and general arrangement- and by the …

Critical Path Problem Under Assignment Constraints With The Number Of Men Less Than The Number Of Activities, S. Kumar, D. Wagner, R. Chandrasekaran

Research Reports from the Department of Operations

The paper concerns the problem of determining the shortest time of project completion under the constraint that the number of men available is less than the number of activities to be performed. Additionally, it is assumed that men differ in skills. In order to solve this problem, two related problems are formulated. The first one does not take into account the constraint that a man cannot perform more than one job at a time. The second one is discrete in time and is used to make a solution of the former problem feasible. An iterative procedure for solving the basic …

Delegation Of Task Functions By Dietitians To Dietetic Technicians, James Lumsden

Loma Linda University Electronic Theses, Dissertations & Projects

Dietetics has been identified as one of the professions in which there is a shortage of qualified personnel. The need to delegate selected task functions to extend professional skills and contain costs has been recognized in many professions faced with a manpower shortage.

This research was done to determine the degree to which dietitians will utilize dietetic technicians in the role proposed by the American Dietetic Association. A questionnaire was the instrument utilized to collect data from the 197 randomly selected hospitals in the continental United States. Task functions identified in the proposed job descriptions for the dietetic technician in …

An Analysis Of The Program For Education Professions Development Act, Part E, Fellowship Students At Utah State University, Ronald Max Rees

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

From the time of the first school through the current schools of today, one of the greatest concerns of educators has been the development of curriculums. "Among the most important educational policies of schools are those pertaining to curriculum." (Kirst and Decker, 1972, p. 28) This concern has been echoed by many educators across the country including those at Utah State University. At Utah State the responsibility of the curriculum for the Education Professions Development Act, Part E, program (EPDA) belongs to the Business Education Department. The fiveyear old EPDA, Part E, program at Utah State University has been deeigned …

Some Algorithms For Solving Extreme Point Mathematical Programming Problems, S. Kumar, D. Wagner

Research Reports from the Department of Operations

The paper concerns some algorithms for solving extreme point mathematical programming problem formulated in [4]. The algorithms discussed consist in determining lower and upper bounds of the objective function and accomplishing the search for the optimal solution. The direction of search depends upon the choice of the starting point. It can be either lower or upper bound. Algorithms making use of the two possible search direction are discussed in detail. In order to illustrate the application of these algorithms, two numerical examples are solved. Some other algorithms based on different approaches are also briefly discussed.

Design And Testing Of A Generalized Reduced Gradient Code For Nonlinear Optimization, Leon S. Lasdon, Allan D. Waren, Arvind Jain, Margery W. Ratner

Research Reports from the Department of Operations

Generalized Reduced Gradient (GRG) Methods are algorithms for solving nonlinear programs of general structure. An earlier paper [1] discussed the basic principles of GRG and presented the preliminary design of a GRG computer code. This paper describes a modified version of that initial design, including the experiences that led to the modifications. This paper also is intended to serve as partial system documentation. The code is compared computationally with an interior penalty function code, and anticipated future work on the algorithm is outlined.
