2. SOME DETAILS OF TECHNICAL SOLUTION


POSTAL AREAS

3

Areas of delivery bases (approx. 247 DBases) Postal delivery districts/routes ( approx. 7.000 districts, containing about 200-600

Stops) ZIP Code Areas (approx. 2200) Other postal Areas (Regions …)

Facility Point / Delivery Base

Service Locations / AdressPoints

LOCATIONS

• Buildings with geocoded delivery adresses ( approx. 2,2 Millions)• Postboxes (approx. 15.000)• Facility Locations (delivery bases /start & end of each Route …, Post Offices, etc )• Postal Access Points (calculated Points connecting Building & street network …)



EXAMPLE / ROUTING SCREEN (OUR ROUTING ENGINE WORKS WITH THE ACCESS POINTS)

AdressPoints AccessPoints ( … closer to street-network than AdressPoints …)


We have finished our homeworks considering of• Geocoding of all AdressPoints (finished 3 years before start routing-project …)• Collecting Experiences with Routing tasks before start our project

(exange of informations with Norway Post /using GIRO, German Post /using GIRO) Foundations of our letter delivery system are changing very quickly

• 50.000 new Buildings/Adresses in each year in Austria detected …• Strong Fluctuating workload

(Christmas time is highly different to Summer Holiday season ...)• Strong Pooling/Merging Trend for Delivery Bases

( …to bigger Areas/Bases with more districts in new delivery bases)

Short Update-Cycles for Workload/Capacity model changes ( … yearly …) We expected Efficiency & Productivity improvements for working with new system Saving costs through high-grade new processing … Preparation for clearance of free Postal Market (in Austria since 2013 ..)

WHY WE NEEDED ROUTE OPTIMIZATION SYSTEM ?


2009 STARTING WITH MARKET ANALYSIS …

SHORT EVALUATION OF „BIG PLAYER OF POSTAL ROUTING“ SOLUTIONS

Implemented to USPS, Swiss Post … Implemented to Canada Post, German Post etc


Results of Evaluations of both Products• Both systems very well-engineered, but we still expected adaptations for Austrian

conditions after implementation …• We finally fear lot of Adaptations for communication with existing Pre-Systems

(Databases …)

OUR MOTIVATION FOR DEVELOPING OF OWN ROUTE OPTIMIZATION SYSTEM

Therefore our finally Decision : Start of Developing of our own Route Optimization System


WE STARTED 2009 WITH PROJECT PARTNERSHIP

Prisma Solutions(responsible for developing of GIS Clients, data management …) MyVision

(design of Interfaces and modeling of Capacity Patterns or Workload Patterns…) University of Vienna

(main task: Design of Optimization Solversusing Mix of: Heuristics, Windy Chinese Postman, Variable Neighborhood Search, Ant colony optimization (ACO) … etc)

PROJECT MAURITIUS


Variable Neighborhood SearchVariable Neighborhood Search (VNS) proposed by (Mladenović, Hansen, 1997[2]) is a metaheuristic method for solving a set of combinatorial optimization and global optimization problems. It explores distant neighborhoods of the current incumbent solution, and moves from there to a new one if and only if an improvement was made …http://en.wikipedia.org/wiki/Variable_Neighborhood_Search

Windy (Chinese) Postman ProblemThe windy postman problem is a generalization of the Chinese postman problem in which the edge-traversal costs are asymmetric. The problem is to compute a shortest tour that traverses every edge of a given graph at least once, and it is known to be NP-hard. http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.22.2569

Inspection of the Route • last control of all route segments (order of stops, positioning of AdressPoints …) before starts

remodeling, resizing• Last chance for small adaptations (add the path sketches to the existing route segments …)

MAURITIUS / MAIN FUNCTIONALITY BLOCKS

Path sketch:

… Add few seconds of service time to travel time …


Remodeling/Resizing/Reshaping„re- cutting“ ofdelivery districts

• Exchange of Adresspoints / stopsbetween two districts(blue one & red one…)

• Reorder of AdressPoints / Stopsbetween two districts



Changing of traffic Restriction & delivery Rules• Change of Restrictions (oneway etc)• Change of delivery Rules (zick-zack, u turns)



Generate new routing Scenarios for whole delivery base areas …(automatic, semi - automatic or manually)

• Downsizing of number of delivery districts (Example: from 50 to 48 districts …)• Upsizing of number of delivery districts (Example 48 to 50 / Reason: more workload

• Remodeling/Reshaping of existing delivery districts• to produce more compact & well balanced new district areas• to produce districts that respect specified boundaries (ZIP Code boundaries …)• to produce districts that respect user-specified work rules & constrains (only 8 hours tours …)

Further Options / Tasks …• Combination of downsizing & remodeling/rebuild• Merging of two or more delivery bases areas to unified new delivery area• Simulation / „what if Analysis „ …• Reduction of optimizing complexity / using street sections instead of single Adresses …

MAIN OPTIMIZING APPROACH USED BY AUSTRIAN POST (PART 1)


EXAMPLE / OPTIMIZING TASK: DOWNSIZING

Part of delivery base area with 15 districts

Before Delivery base Downsizing:

The same part of delivery base area

after rebuild & downsizing with 10 districts

After Delivery base Downsizing:


Generate new routing Scenarios for separate delivery districts

• Create routes with optimized (sequenced) new order of stops, that respect:• Traffic street network restriction (one way etc …)• User-specified, network oriented restrictions (zick-zack delivery, u-turn delivery …)• User-specified, service location oriented restrictions

(several service time spent on each stop point, time windows for servicing of stops …)

MAIN OPTIMIZING APPROACH USED BY AUSTRIAN POST (PART 2)
