Irene Toth Interview, 2008
No full textIrene Toth, a member of the board of trusttees of WCPC and an amatuer historian discusses both the history of the West Creek area and her life in Cleveland since 1928. Also discussed are the positive environmental effects of the project and the social identification of the naturalist group she is a part of. Toth also examines the group\u27s future and transition from a single-issue committee to a conservancy advocate

Solving real-world ATSP instances by branch-and-cut
No full textRecently, Fischetti, Lodi and Toth [15] surveyed exact methods for the Asymmetric Traveling Salesman Problem (ATSP) and computationally compared branch-and-bound and branch-and-cut codes. The results of this comparison proved that branch-and-cut is the most effective method to solve hard ATSP instances. In the present paper the branch-and-cut algorithms by Fischetti and Toth [17] and by Applegate, Bixby, Chvátal and Cook [2] are considered and tested on a set of 35 real-world instances including 16 new instances recently presented in [12]. © Springer-Verlag Berlin Heidelberg 2003

Helyn Toth interview, 13 July 2011
No full textThis is Helyn Toth\u27s second interview, a follow-up to her interview about growing up on the Hunt Farm in Everett, Ohio. In this interview, Helyn focuses on the nearby Point Farm, (now called the Point-Biro Farm), that was started in the early 1880s by her great-grandfather Nathanial Point. On the Point Farm, the Point family mainly raise dairy cattle and shipped the unprocessed milk to milk companies in Akron
Classical Exact Algorithms for the Capacitated Vehicle Routing Problem
No full textIn this chapter we present an overview of the early exact methods used for the solution of the Capacitated Vehicle Routing Problem (CVRP). The CVRP is an extension of the well-known Traveling Salesman Problem (TSP), calling for the determination of a Hamiltonian circuit with minimum cost visiting exactly once a given set of points. Therefore, the foundation of many exact approaches for the CVRP were derived from the extensive and successful work done for the exact solution of the TSP. However, even if tremendous progress has been made with respect to the first algorithms, such as the tree search method by Christofides and Eilon [17], the CVRP is still far from being satisfactorily solved. Our analysis encompasses more than three decades of research and examines the main families of approaches, from direct tree search methods based on Branch-and-Bound to column generation and Branch-and-Cut algorithms presented around the year 2000. The wide variety and richness of methods proposed in these early decades of CVRP history is witnessed by the good number of survey works that analyzed the relevant literature. Following the first comprehensive work of Laporte and Nobert [39], several review papers were devoted to the analysis of exact algorithms for the VRP as those of Laporte [36], Toth and Vigo [52, 53], Bramel and Simchi-Levi [15], Naddef and Rinaldi [47], Cordeau et al. [20], and Baldacci, Toth, and Vigo [10,11]. More recent Branch-and-Cut-and-Price algorithms, which have successfully combined and enhanced those described in the following, will be covered in detail in Chapter 3

The application of international standards of quality management in a local governance
No full textCilj ovog rada je da ukaže na mogućnosti primene generičkih i specifičnih međunarodnih standarda menadžmenta kvaliteta razvijenih u tehničkom komitetu međunarodne organizacije za hstandardizaciju ISO/TC 176 u jednicama lokalne samouprave. U ovom radu pod generičkim standardima se posmatraju standardi koji se mogu primeniti u organizacijama bez obzira na njihovu delatnost, veličinu, tip, način organizovanja ili neku drugu specifičnost. U ovom radu pod specifičnim, za jedinice lokalne samouprave, analiziraće se međunarodni standardi posebno razvijeni za primenu u jedinicama lokalne samouprave. Razvoj i primena međunarodnih standarda u jedinicama lokalne samouprave imaju brojne specifičnosti. Zakoni koji definišu osnivanje, rad i organizovanje jedinica lokalne samouprave su različiti od zemlje do zemlje. Međunarodni standardi koji se odnose na menadžment i obezbeđenje kvaliteta, i koji se razvijaju u okviru ISO/TC 176 nisu dovoljno poznati zaposlenima u jedinicama lokalne samouprave, a potrebe tržišta koje je prepoznao sekretarijat ovog tehničkog komiteta u definisanju posebnih standarda (ISO18091: 2015) i tehničkih specifikacija (ISO TS 17582 : 2014) govore da će se standardi u oblasti menadžmenta kvaliteta u lokalnoj samoupravi dalje razvijati.The aim of this paper is to point out the possibility generic and specific application of international quality management standards developed in the technical committee of the international organization for standardization ISO / TC 176 in local government units. Generic standards are observed in the paper, the standards that can be applied in organizations regardless to their activity, size, type, and way of organization or some other specificity. Specific local government units and international standards specially developed for implementation in local government units will be analyzed in this paper. The development and application of international standards in local government units have numerous specificities. Laws that define the establishment, operation and organization of local government units vary from country to country. International standards relating to management and quality assurance developed within ISO / TC 176 are not sufficiently familiar to employees in local government units, and the market needs recognized by the secretariat of this technical committee in defining specific standards (ISO18091: 2015) and technical specifications (ISO TS 17582: 2014) indicate that standards in the field of quality management in local government will continue to develop
Algorithm 750: CDT A Subroutinefor the Exact Solution ofLarge-Scale, Asymmetric Traveling Salesman Problems
No full textThe FORTRAN code CDT, implementing the algorithm of Carpaneto, Dell'Amico and Toth 1995afor the Asymmetric Travelling Salesman Problem, is presented. The method is based on the Assignment Problem relaxation and on a subtour elimination branching scheme. The effectiveness of the implementation derives from reduction procedures and parametric solution of the relaxed problems associated with the nodes of the branch-decision tree
