Interval estimation of the work duration deviations while time management in the projects design engineering of vessels
(2014) Prykhodko, S. B.; Приходько, С. Б.; Kudin, O. A.; Кудин, О. А.
The application of interval estimation of deviation of work duration under the time management of projects of design vessels documentation development has been studied. The aim of the study is to determine the possibilities to apply the interval estimation of deviation of work duration on the basis of normalizing transformations. This will reduce the probability of exceeding the time and budget of projects of design vessels documentation development. The Johnson’s normalizing transformations and rules of interval arithmetic are applied to determine the deviation of work duration in projects of design vessels documentation de-velopment. Three types of interval deviation of work duration in projects of design vessels documentation development are determined. The example of usage of interval estimates of deviation of work duration is given on the basis of Johnson’s normalizing transformations in projects of design vessels documentation devel-opment. The research results can be used under the time management of projects of design vessels documentation development. This improves the reliability of estimation of work dura-tion deviation and helps to make the informed decisions to change the schedule of projects of design vessels documentation development.
