The Software ''Technological Diary'', which was elaborated in 1992, wa
s determined to improvement of activity of sugar factory by computatio
n and storage of laboratory dates in computer. This proceeding simplif
ies, accelerates and improves work in factory laboratory. There is pro
cessed approximately 500 dates during one day of campaign. The control
activity of a operational technologist is improved by complex view of
technology. This view makes the quick processing of necessary indices
possible. It comes to saving of operational costs. The elaborated set
s of programmes are the basis for individual proposals destinated for
further sugar factories. The modifications of computer programme for i
ndividual sugar factories will be a consequence of different equipment
of laboratories, practices and technology in a sugar factory.
