Wright’s Savings Algorithm Jens Lysgaard (translated by Michael M. Sørensen) Department of Management Science and Logistics The Aarhus School of Business Fuglesangs Allé 4 DK-8210 Aarhus V September 1997 1. Introduction. In 1964 Clarke & Wright published an algorithm for the solution of that kind of vehicle routing problem‚ which is often called the classical vehicle routing problem. This algorithm is based on a so-called savings concept. This note briefly describes the algorithm and demonstrates

ALGORITHM Informal Definition: An Algorithm is any well-defined computational procedure that takes some value or set of values as Input and produces a set of values or some value as output. Thus algorithm is a sequence of computational steps that transforms the i/p into the o/p. Formal Definition: An Algorithm is a finite set of

CHAPTER 2 Cuckoo Search Algorithm This chapter provides a breif introduction to the area of Nature Inspired Algorithms and its classification. Among all the categories‚ Swarm intelligence will be the main area of focus. Various swarm intelligence techinques will be discussed in the later sections. Cuckoo Search Algorithm is also one of the latest swarm intelligence technique which is focused in this dissertation to solve the problem discussed in chapter 1. 1. Nature Inspired Algorithms Nature has always

Management of High Tech Services (HTS) would like to develop a model that will help allocate its technician’s time between service calls to regular contract customers and new customers. A maximum of 80 hours of technician time is available over the two-week period. To satisfy cash flow requirements‚ at least $800 in revenue must be generated through technician time during the two-week period. Technician time for regular customers generates $25 per hour. However‚ technician time for new customers

CHAPTER 1 INTRODUCTION Competitiveness in today’s marketplace depends heavily on the ability of a company to handle the several important challenges like reducing total supply chain operating cost and reducing lead-times‚ increasing customer service levels‚ and improving product quality. In Figure a typical non integral supply chain is shown‚ in which the goods flow starts as raw materials at natural resources and ends with products at final customers. Raw material winners keep

Euclidean algorithm In mathematics‚ the Euclidean algorithm‚ or Euclid’s algorithm‚ is a method for computing the greatest common divisor (GCD) of two (usually positive) integers‚ also known as the greatest common factor (GCF) or highest common factor (HCF). It is named after the Greek mathematician Euclid‚ who described it in Books VII and X of his Elements. The GCD of two positive integers is the largest integer that divides both of them without leaving a remainder (the GCD of two integers in
