Computational Experience With A Traveling Salesmen Algorithm, Joseph A. Svestka, Vaughn E. Huckfeldt

Research Reports from the Department of Operations

A formulation of the traveling salesman problem with more than one salesman is offered. The particular formulation has computational advantages over other formulations. Experience is obtained with an exact branch and bound algorithm employing both upper and lower bounds (mean run time for 55 city problems is one minute). Due to the special formulation, certain subtours may satisfy the constraints, thus reducing the search. A very good initial tour and upper bound are employed. The determination of these as well as the pathology of the formulation and the algorithm are discussed. No increase in computation time over the one salesman …

Application Of Operations Research In Research Planning - A Case Study, Eric C. Johnson

Research Reports from the Department of Operations

In 1966 Kennecott Copper Corporation and its subsidiary, Chase Brass and Copper Company, launched a long range research effort--the Casting Laboratory-- designed to focus on the area of casting, specifically solidification and liquid metal processing. From the outset, the Casting Laboratory implemented formal activities for the identification and evaluation of research opportunities and activities so that the results could be used for long range planning of Casting Laboratory applied research programs. The author was responsible for these activities during 1967-1970. Drawing on specific activities carried out at the Casting Laboratory during the author's tenure there and activities in which he …

Timeliness Of Library Materials Delivery: A Set Of Priorities, Arnold Reisman, J.P. Herling, M.G. Fancher Beeler, G. Kaminski, S. Srinivasan

Research Reports from the Department of Operations

This paper describes work performed to obtain a set of aggregate priorities and of values for the timeliness of delivery of library materials. The priorities were expressed through a set of weights and utility curves for eleven categories of materials handled in whole or in part by approximately 800 libraries located in the Greater Cleveland area. To obtain the needed data a panel of librarians representing several types of libraries used the Delphi Method of arriving at consensus. The results described in this paper are being used as input information in a project aimed at establishing optimum library delivery truck …

Integer Programming : Dual Fractional Mixed Integer Programming (Gomory [2]), Harvey M. Salkin

Research Reports from the Department of Operations

This work represents the fourth chapter of a forthcoming textbook “Integer Programming” to be written by Harvey M. Salkin. The mixed integer programming algorithm developed by Ralph Gomory in 1960 and presented in this chapter is a direct extension of the integer programming algorithm discussed in Chapter 3. As before, the cutting plane technique utilizes the dual simplex method and allows fractional numbers in computation and is thus classified as "dual fractional." For ease of reference, we rewrite the basic approach.

Integer Programming : Dual Fractional Integer Programming (Gomory [3]), Harvey M. Salkin

Research Reports from the Department of Operations

This work represents the third chapter of a forthcoming textbook “Integer Programming” to be written by Harvey M. Salkin. This chapter concerns itself with a cutting plane algorithm for the integer program which utilizes the dual simplex method and allows fractional numbers in computation - hence the "dual fractional" reference. We outline the basic approach for the integer program extension to the mixed case appears in the next chapter.

An Efficient One-Dimensional Search Procedure For Barrier Function, Leon S. Lasdon, Richard L. Fox, Margery W. Ratner

Research Reports from the Department of Operations

Interior penalty functions are a popular approach for solving non-linear constrained optimization problems. Most current methods for minimizing such functions require a one-dimensional minimization along specified search directions, and this can be quite difficult, since the function approaches +∞ along the boundaries of the feasible set. A special purpose algorithm is described which alleviates this difficulty by using a simpler approximating function which also goes to infinity near the boundary. Numerical results are presented, showing that the number of function evaluations and computation time are reduced by factors of about three and two respectively. The ideas are easily extended to …

Mathematical Modeling Optimization And Simulation Improve Large-Scale Finished Goods Inventory Management, Michael S. Salvador, Muhittin Oral, Arnold Reisman, Burton V. Dean

Research Reports from the Department of Operations

This article describes an inventory control study conducted for a large manufacturing company involving the distribution of over 7,000 line items through six major warehouses and nearly 800 authorized distributors across the U.S. The study's success, rare in systems of this scale, addressed challenges including unfamiliarity with research methods, inadequate evaluation of parameters, and lack of practical recommendations. A task force comprising operations research faculty, graduate students, and company managers collaborated to optimize inventory control while maintaining a predetermined service level. The study focused on evaluating holding, setup, and shortage costs, with a particular emphasis on shortage costs. Extensive computer …
