Network Analyst

Pubblicato: Martedì, 20 Maggio 2014 Scritto da Supergeo Italia

SuperGIS Network Analyst consente di eseguire delle analisi basate su un grafo stradale. Le analisi possono essere di vario tipo come un piano per i trasporti, la ricerca della via più breve per raggiungere un determinato punto o la ricerca della via più conveniente.

 

Caratteristiche

SuperGIS Network Analyst consente 7 tipi di analisi di rete (network analysis):

  • Shortest Path,
  • Closest Facility,
  • Service Area,
  • Superior Route Planning,
  • Location Analysis,
  • Vehicle Routing Problem,
  • Location Allocation.

 

Shortest Path

  • Support One to One, One to All, and All to All.
  • Support users to set up Start, flags and End on the map straightly.
  • Support to assign order, including return or not.
  • Support users to calculate by time or distance unit cost.
  • Support to present the result in table, containing road name, cost of each segment, and direction.
  • Support to assign Time Windows and whether or not to consider Time Windows in calculation.
  • Support to search the superior route of two flags by Dijkstra and A* algorithm, and provide an adjustable parameter to generate other replacement road.
  • Support to import files of different Weight settings.
  • Support to set up the connectivity of two intersected segments.
  • Support users to set up barriers on the map straightly.

 

Closest Facility

  • Support users to mark the point (event) used to search the closest facilities with cursor on the map.
  • Support users to type quantity of facility to search.
  • Support users to perform searching by time or distance unit.
  • Present in table the relevant attribute data of facility searching result.

 

Service Area

  • Support users to mark the point on their own.
  • Support users to set up searching range.
  • Support to present the result in road tree for demonstration.
  • Support to calculate by time or distance unit.

 

Superior Route Planning

  • Support users to mark the Start with cursor on the map.
  • Support users to set up whether or not to assign terminal.
  • Support users to set up whether or not to return.
  • The Superior Route Planning supports Nearest Neighbor, Farthest Insertion, Sweep, Simulated Annealing and Genetic Algorithm.
  • Support to set up distance, time, and weight values of early arrival time and late arrival time.

 

Location Analysis

  • Support 3 types of analyses, including Minimum Spanning Tree, Center Problem, Median Problem.
  • Support users to mark with the cursor the Flags and Barriers on the map.
  • Support to present in table the searching result.

 

Location Allocation

  • Allocate the facilities with the lowest cost to each demand point; can be used for allocating schools, hospitals, libraries, etc.
  • Support 3 problem types: Minimize impedance, Maximize coverage, Maximize attendance.

 

Vehicle Routing Problem

  • Support users to straightly mark vehicles and flags on the map.
  • Support to assign Time Windows, stay time and cargo weight of flag.
  • Support to set up Time Windows and maximum loading of vehicle.
  • Superior Route Planning supports Simulated Annealing and Genetic Algorithm.
  • Support users to calculate by time or distance unit cost.
  • Support to present in table the searching result, containing road name, segment cost and direction of each vehicle coming over, total distance and time of the vehicle.
  • Support to set up weight values of travel time, early arrival time, late arrival time and overloading.

 

Supported format

  • Support vector format in GEO (SuperGeo GEO Format) and Shapefile.
