Mobile Computing at Munich Airport: from Cost-Benefit Analysis to Implementation. Course Outline

Transcription

1 GI12-3 Mobile Computing at Munich Airport: from to Implementation Wolfgang Haller Stephan Plabst Munich Airport International has been using CAD and GIS since This class describes recent efforts to implement mobile computing technologies, including Autodesk Envision TM and Tablet PCs, to support facility management and other business processes. We will discuss the cost/benefit approach we used to evaluate the technologies. We will also demonstrate with actual examples how these technologies, combined with AutoCAD, Autodesk MapGuide, GPS, and a wireless LAN, can be implemented to improve the management of airports and other large facilities. Course Outline Scenario at the Munich Airport International Theoretical approach Different ways to introduce new technology Mobile computing Cost-benefit analysis Analysis of existing business processes Selected pilot processes Realizing new workflows Realized Prototypes Pavement Management Technical building management Scenario at the Munich Airport International Overview of the Airport The new airport of Munich went operational in It is now Germany s second largest airport and number nine in Europe.

2 Scenario at the Munich Airport International Various Business Processes In many ways airports operate in similar fashion to small cities: they cover large areas of land, have numerous departments responsible for the maintenance of specific infrastructure segments. Pavement, buildings, power network, water/wastewater systems and traffic are all elements whose proper management and safe operations are relied upon by airports and cities alike. So their business processes are not only to handle passengers, cargo and aircraft, but also building and infrastructure-management. Scenario at the Munich Airport International Modern Technology as Chance for the Future CAD/GIS was introduced in As the buildings had been completely designed on the drawing board, a lot of data had to be captured. Surveyors delivered data from the very beginning. So over 1 million measured points could be put into the database. AutoCAD, Map, MapGuide and Oracle are the most important systems for graphical data. In 2003 Munich Airport started with mobile computers using CAD/GIS data. Different Ways to Introduce new Technology In a company the introduction of new technology is only possible if you can prove its profitability. Different approaches for this are: Feasibility study Cost-benefit analysis Developing a prototype

5 Selected Pilot Processes Door inspection Key cylinder inspection Technical building management Check and planning of the electrical installations Sales / Customer service Pavement Management Cleaning management Investigating the current process (1) The business processes were examined by following the respective operatives doing their work Afterwards the workers were interviewed and asked to describe the current workflow for their business process How often per year? How many people? Needing how long? Using how many material or machines? Investigating the current process (2) Example: Pavement Management Typical damage on a concrete slab Paper acquisition list for these damages

6 Defining a new Workflow for the Process (1) Based on the existing workflow, the business processes were redesigned using mobile computing To calculate the gain compared to the old way, different factors were estimated How much faster? How many people less? What savings on material and machines? What improvements in process quality? And thus the cost effectiveness could be calculated Defining a new Workflow for the Process (2) Example: Pavement Management using mobile computing with MapGuide, Oracle and GPS Cost Effectiveness and Payback Period 3,5 350% 3 300% 2,5 250% Payback Period [Years] 2 1, % 150% 100% Cost Effectiveness 0,5 50% 0 0% Technical Building Management Pavement Management Sales / Customer Service Key Cylinder Inspection Check and Door Inspection planning of the Electrical Installations Cost Effectiveness Payback Period

7 Realized Prototype Pavement Management (1) Supported with mobile computers, the new process looks like this: The workers drive in their car and look for damages of concrete slabs. At a damage they locates their position using GPS. As WLAN is available, MapGuide shows the drawing of the apron with a red point-symbol at the current position. By double-clicking the point-symbol, alphanumeric data (information about the damage) can be entered into the Oracle-database. The damage is registered. Realized Prototype Pavement Management (2) A laptop with GPS for localization of the damage Position of damage shown in MapGuide Realized Prototype Pavement Management (3) Other workers have to repair the damage. But it is difficult to find it (as all the slabs look the same). The workers now use a mobile computer and take a car to drive to the apron where the damage is. MapGuide shows the map (the damage again is marked with a red point-symbol); a green pointsymbol shows the current position of the worker. While driving into the direction of the damage (red point-symbol) the green point-symbol moves closer. When red and green point-symbols have (almost) the same position, the damage is reached and can be repaired.

8 Realized Prototype Pavement Management (4) Position of damage Position of car Realized Prototype Technical Building Management (1) The new process with mobile computers is shown in the following charts: Helmut and Robert keep the floor plans and electrical data up-todate; they save their work in dwg-files. Johann copies the files he needs to his tablet pc. Then he drives to the terminal building to make his inspections; he checks the lights, emergency exits, technical installations etc., He uses Envision and its redlining to mark his information in the floor plan. He inserts the information into a work order (in Excelformat) and sends it by directly to the workshop. Marcus opens the mail, finds a work order and a floor plan showing the location.
