| Footage description: | Film shots of burning buildings and of firemen fighting the fire. Commentary by Roy Nelson introduces the programme. Nelson goes on to point out the importance of having fire stations near, potential fires and illustrates the problem by drawing a network of three villages whrch are to be protected by a single fire station. He works out the optimum location for this. Over shots of Rotterdam and of some of its fire stations, Nelson gives background information on the study done by the University of Twente to optimise the location of that city's fire stations. He goes on to explain how the system works now. Sjverd Baas, a member of the team which developed the fire station location plan, explains the fire fighting situation in Rotterdam before the study. He uses a map and film shots of the city to illustrate his points. Baas goes on to explain how his team went about developing their network model. Shots of Rotterdam streets and of a map of the city. Roy Nelson explains that before the Rotterdam problem could be solved, it was necessary to be able to solve P centre problems. He points out that these were not well understood until the early 1970s. Nicos Christofides, Imperial College, London, explains how to solve P centre problems (to any desired accuracy) with an iterative algorithm. Using diagrams, he works out a two centre solution for a network of six villages. He briefly explains what would happen if the distance parameters changed. Roy Nelson takes the solution above further and explains how to find P centres and the critical distances in the general case. He draws a diagram of a three village network and works out one, two and three centre solutions. Sjverd Baas explains how the location algorithm was applied in practice in Rotterdam. He points to a map of Rotterdan as he talks. Roy Nelson summarises the programme, over shots of fire engines on call out in Rotterdam. |
