| Tiivistelmä: | The basic one-depot vehicle-routeing problem belongs to the class of combinatorial optimization problems which can be solved principally by complete enumeration, i.e. the creation of all feasible solutions and selection of the best. A generalized chain-exchange principle for the basic problem is presented which can be numbered among the improvement procedures removing just one or two customers. The chain-exchange process is shown for problems with up to 100 customers, which can be solved on microcomputers with justifiable use of computing time. |
