From Reactive to Proactive Planning of Ambulance Services (REPRO)

Period: 01.03.2012 - 29.02.2016
Coordinator: Prof.dr. R.D. van der Mei

In life threatening emergencies where every second counts, the on time arrival of an ambulance can mean the difference between life and death. For emergencies the following quality requirements are made in practice: in 95% of the cases, the arrival time of an ambulance is not allowed to be longer than 15 minutes. To achieve such short arrival times at affordable rates a sophisticated planning of necessary ambulance rides is necessary. In realizing an efficient planning of ambulance rides many questions play a role, both at a tactical, strategic, as at an operational level. Typical questions are: In which way can the number of calls, depending on time and location, be predicted accurately? How can we properly anticipate and respond to peaks in demand for ambulances? How many pitches for ambulances do we need and what are the optimal locations?  The problem is that the existing planning methods usually assume that the demand for and availability of ambulances are known in advance, but those methods are usually very sensitive to changes in these input parameters. It is the underestimation of these uncertainties that leads to inefficient and therefore expensive, planning of ambulance rides. To solve this problem groundbreaking research is needed that focuses on the development of new, scalable, planning methods which are robust to changes in environmental factors [by explicitly taking into account the uncertainty factor in the ambulance service process, both in real time and in non real time. 


Relization of Reliable and Secure Residential Sensor Platforms (RRR)

Period: 01.08.2010  - 30.07.2015
Coordinator: Prof.dr. R.D. van der Mei
Members: Drs. M. Onderwater, dr. M.C. van Lieshout

The research in the RRR project is on wireless sensor networks (WSNs) and the data that is produced by such networks, with a special focus on residential applications. We look at a variety of topics within this setting, for instance optimal caching strategies, distributed data storage, sensor middleware components, and integration of WSNs into a business context. For these topics, we expect to use techniques from statistics, queueing theory, data mining, and software engineering. The project partners are CWI, University of Twente, Thales, Munisense B.V., and ADT Fire & Security.
