Abstract

VILLAGRA, Andrea; DE SAN PEDRO, Eugenia; LASSO, Marta  and  PANDOLFI, Daniel. Multirecombinative Algorithm for Dynamic Scheduling of Maintenance of Oil Fields. Inf. tecnol. [online]. 2008, vol.19, n.4, pp.63-70. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000400009.

The development of a computer tool named PAE (Scheduling based on an Evolutionary Algorithm) that improves the dynamic schedules of the maintenance of oil fields, is presented. This tool uses a multirecombinative evolutionary algorithm generator of multiple solutions to this problem. The results were compared with information of historical schedules facilitated by the company. The obtained results have been satisfactory concluding that the use of this tool improves the total timing of the original schedule and dynamic re-scheduling is allowed keeping the same quality level in the results.  Finally, the benefit of this should be observed from two points of view: the decrease of the maintenance cost and the reduction of the probability of falling or contingencies in the production.

Keywords : oil fields; evolutionary algorithm; scheduling; maintenance.
