Troj-Variantné Spracovanie A Vyrovnanie Observácií A Určovaných Odhadov/ Three-Variant Processing and Adjustment of Observations and Determined Estimations

Abstrakt Predmetný článok sa zaoberá trivariántnym spracovaním a určením odhadov neznámych parametrov v geodetickej sieti observovanej technológiu využívajúcou signály globálnych navigačných satelitných systémov v rokoch 2004, 2008 a 2011. Cieľom práce je zhodnotiť vplyv použitej metódy vyrovnania na odhad parametrov prvého a druhého rádu geodetickej siete a prezentovať výsledky analýzy pretvorení s grafickou vizualizáciu jednotlivých spracovaní a analýz. Na spracovanie a vyrovnanie observácií boli použité MNŠ a robustné M-odhady podľa Hubera a Hampela. Pri analýze stability bodov poukázali všetky 3 metódy spracovania na posun bodu 5005 v epoche 04-08, čo potvrdzujú aj grafické vizualizácie pomocou konfidenčných elipsoidov chýb. Abstract The present article deals with three-variant processing and finding estimates of unknown parameters in a geodetic network by the technology of global navigation satellite systems in 2004, 2008 and 2011. The assessment of the impact of a used method of adjustment on the estimation of parameters of the first and second order of the geodetic network and the presentation of results of a deformation analysis with graphical visualisation of individual processing and analyses are the objectives of this paper. An LSM method and robust M-estimates according to Huber and Hampel were used for the processing and adjustment of observations. All three processing methods showed a displacement of point No. 5005 in the epoch 04-08 in the analysis of the stability of points, which is also confirmed by graphical visualisations using confidence error ellipsoids.

Integrated Risk Management and its Influence to the Increasing of the Firm’s Value

Successful business subject should to manage its risks in long term and to achieve sufficient profit for covering of unexpected losses. Management of risks is process that is used in business practice for identification, management and avoiding of risks in area of business. With aim to evaluate influence of integrated risks ́ management we used method of value stream analysis. This method serves for identification of risks, resulting from wasting of sources in production or administrative processes. During research and measurement we dealt with stocking process of production lines in the frame of internal material flow. According monthly observing of process of production lines stocking we found out 5 mistakes, for which we recommended possible solution that could help to optimize searching process and eliminate mistakes, which caused losses in the company.
