Why AGV? - Det Effektive Hospital
This is why AGV´s are used in Hamburg Eppendorf & Klagenfurt AGV as part of global logistic considerations in a hospital MMG engineering company l l l l l l Founded in 1999 30 engineers and employees for administration 13 technical employees for service & maintenance in 5 projects Head office in Berlin Branch office in Vienna Our focus: technical solutions as part of global logistic considerations in a hospital – especially for AGV systems and pneumatic tube systems.

12 - Why AGV? l Hospitals often ask the same questions l l l l l l l Can AGV help us to structure our processes better? Can AGV support us using our existing infrastructure? Can AGV reduce dependency on employees and manual labor? Can AGV increase the reliability of our transportation? Can AGV offer flexibility for future reorganisations of the hospital? Can AGV help us save money? As shown in the case of Hamburg and Klagenfurt, the answer is: MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 13 - Calculating economic efficiency l l l As the first step in an AGV planning project the economic efficiency has to be proved To determine the economic efficiency for an AGV system in a hospital, we compare a manual transportation system with an AGV system. For both systems the same basic data is used. l l l Distances Number of (AGV) trips Costs l l l l Installation Maintenance Energy Evaluation of required infrastructure MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 14 - Calculating economic efficiency The basic data is then filled into the calculation sheet to evaluate the costs and other aspects needed according to the guidelines of the Evaluation of economic efficiency of Automated Guided Vehicles (VDI 4450). Calculating economic efficiency Next the data is entered into the spreadsheet to calculate the economic efficiency of the AGV system. The decision for an AGV system is generally made with an ROI around 7 years. AGV systems have a lifetime of about 20 years. MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 16 - Calculating economic efficiency Results Klagenfurt hospital: l The calculated ROI is ~ 5,5 years. l Due to the AGV around 37 less employees are needed l ~ 1 M EUR saved in labor costs per year l The real ROI will be longer, but still with less than the lifetime of the AGV Hamburg University hospital: l The ROI is ~ 3 years. l Due to the AGV around 47 less employees are needed l ~ 1,65 M EUR saved in labor costs per year MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 17 - Non-monetary reasons for choosing AGV l Hamburg University Hospital l l l l Modern reputation Goal to become most modern hospital in Europe Possibility to optimize processes and thus save time Klagenfurt: l l l Technical necessities Technical system needed to make the use of heavy roll containers (for e.g.) possible AGV enables more flexibility for the layout of the hospital (e.g. to separate the service departments from the hospital wards). MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 18 - AGV planning tools l l l Both hospitals chose an AGV system The next step was to bring this idea to life by means of effective planning We used a number of tools developed by MMG to do so: l l l Checklist for the main interfaces and basic necessities AGV timetable Number of vehicles calculation MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 19 - AGV planning – design phase AGV planning target – optimal implementation of AGV into a hospital with its specific needs This includes: l Review and confirmation of the built environment, l Review of corridor and door sizes required for all vehicle types, l Interfaces: l l l l Human interfaces including avoidance of malicious use, Facilities management (FM) interfaces (e.g. repairs and maintenance), Information technology (IT) interfaces, Other electronic system interfaces (e.g. security, fire and emergency, call systems, doors, lifts, etc.) MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 20 - AGV planning – design phase AGV planning target – optimal implementation of AGV into a hospital This includes: l Roll container requirements, usage for specific items and RFID-recognition of roll containers, l Minimum parking and storage requirements l Evaluation of future developments, so as not to limit AGV and roll container functionality. MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 21 - AGV planning – design phase MMG developed its own checklist that has been established successfully in many AGV projects. Main aspects are: Architecture Mechanical equipment Elevators IT Other existing systems In the design phase every question needs to be answered. MMG mbH 2013, Weitergabe an Dritte nur mit schriftlicher Zustimmung seitens MMG - 22 - AGV planning – evaluation phase At the same time, it is necessary to calculate and evaluate the basic data of the AGV 1. AGV timetable For this it is necessary to evaluate the following data: Ø Number of trips between the sending / receiving stations for each category of goods, Ø Distances – horizontal and vertical Ø Duration of each trip, Ø Decisions about time slots for the trips on a 24 hour basis. The AGV timetable is based on the day with the maximum number of trips (for example a Thursday with max. occupancy).
