1. Description of the subject area (2 tasks)

     We consider here two tasks: one solvable and other perspective to minimize losses from downtime of the broken territorially distributed objects of the urban network of housing and communal services (HCS), which are served by one (for the solvable task) or by several (for the perspective task) mobile repair teams (MRTs).

     To solve these tasks is needed the databases of roads networks (DBRNs) for corresponding cities. Each such task is solved in two stages. In the first of them are found optimal routes of passing any possible pairs of target points (TPs) by transport vehicles (TVs), which deliver MRTs to destinations, and in the second stage — optimal order of passing all TPs.

     Both of these tasks can be solved numerically by using the new science-intensive network technology called "Information technology of automation of control of discrete technological and information processes (in short IT AC DTIP)", because optimizable process has all necessary properties for that. This process is discrete and is classified as a time-limited process. Its elements in terms of DTIP are:

  • network of city roads a network demand;
  • MRTs and TVs — devices of service.
