Optimization of sequence of performing heterogeneous repair work for transport systems by criteria of timeliness

摘要

For many transport systems a necessity of performing in time a set of heterogeneous repair work exists. Several works should be performed by one repair brigade in crossed time. And conditions for performing different repair works are characterized by uncertainties. There exists given term for each work and possible damages or the missed benefit if the performance of works isn't well-timed. Taking into account these factors the sequence of performing heterogeneous repair work essentially affects an efficiency of system. For transport systems the multiparameter dispatcher technology, criteria and method for optimizing sequence of performing heterogeneous repair work are proposed. The rational sequence of works is defined by criteria of timeliness on the base of the best choice from different dispatcher technologies and the used parameters (such as distribution work calls types on priorities, distribution of calls priorities on groups, appointment of technologies inside of groups). Effects are demonstrated by example.
