ΕΠΙΛΥΣΗ ΠΡΟΒΛΗΜΑΤΩΝ ΧΩΡΟΘΕΤΗΣΗΣ ΚΕΝΤΡΩΝ ΠΑΡΟΧΗΣ ΥΠΗΡΕΣΙΩΝ ΣΕ ΔΙΚΤΥΟ

THE SUBJECT OF THIS THESIS IS THE SOLUTION OF THE FACILITY LOCATION PROBLEM (FLP) IN SUCH WAY THAT ANY DEMAND POINT CAN BE SERVICED BY A FLP IN A TIME-DISTANCE LESS THAN A GIVEN T (PROBLEM (F)). PROBLEM (F) BELONGS TO THE WELL KNOWN CATEGORY OF NP-HARD PROBLEMS AND UNTIL NOW IT IS TACKLED UNDER THE FRAMEWORK OF THESET COVERING PROBLEM (SCP). IN THIS THESIS THE PROBLEM (F) IS SOLVED UNDER THEFRAMEWORK OF THE THEORY OF EXTERNALLY STABLE SETS (ESS) OF GRAPH THEORY. THE THESIS CONSIST OF SIX CHAPTERS. CHAPTER ONE PRESENTS SOME ELEMENTS OF GRAPH THEORY AND THE METHODOLOGY OF IMPLICIT ENUMERATION ALGORITHMS. CHAPTER TWO DISCUSSES A SURVEY OF THE DIFFERENT LOCATION-ALLOCATION PROBLEMS AND THE WELL KNOWN MODELS. CHAPTER THREE ANALYZES THE MOST IMPORTANT PAPERS IN THE CORRESPONDING LITERATURE. IN CHAPTER FOUR WE DEVELOP TWO NEW ALGORITHMS FOR THE GENERATION OF THEFAMILY OF MINIMAL ESS WHICH LEADS TO TWO ALGORITHMS FOR THE FINDING OF THE MINIMUM ESS. CHAPTER FIVE SOLVES THE PROBLEM IN QUESTION WITH THE USE OF THE ALGORITHMS OF CHAPTER FOUR TO REAL LIFE LOCATION PROBLEMS. FINALLY CHAPTER SIX PRESENTS OUR COMPUTATIONAL EXPERIENCE, AND A COMPARATIVE STUDY BETWEEN THE PROPOSED ALGORITHMS AND THE ALGORITHMS OF CHAPTER THREE.
