Studie práce se zádovými postřikovači s dopadem na návrh norem spotřeby času na Školním polesí Valšovice
Horák, Karel
The young stand protection against the forest weed is one of the frequent operations in forestry sector. During the protection treatment is widely used knapsack sprayer for pesticide application. Also in this field of operation together with the keeping the quality of the work, the innovation towards better ergonomic of the operator and/or lower amount of the agent application is noticed. Due to this innovation and development of new models of the sprayers the analyses of the operators is necessary to be able well set the salary and to be able to motivate the employees. Therefore the aim of the thesis was to analyse the operation with knapsack sprayers and based on the results to set the correct work standards.

Comparison of the Performance of Individual Wood Logging Methods
Pudlo, Pavel ; Macků, Jan (advisor) ; Štícha, Václav (referee)
The aim of the bachelor thesis was to perform literary research on the topic of the productivity of individual wood logging methods for forest cover and verify this productivity by comparison of the time dimensions either by using the harvester or working with the woodcutters. The main contribution of the thesis research results are own measurement. Measuring of the productivity of individual wood logging methods was carried out in the conditions given by the method cut to length by salvage cutting, that launched because of hit by bark beetle or strong wind. The measurement was carried out on five stands with harvester and on two stands with woodcutters. It was a measure of one harvester operator and four woodcutters. The measurement was done with the help of cameras that caught the working times of woodcutters and the harvester. The resulting times, due to the productivity and stem volume of the trees, recorded times by harvester were better and for that reason that method had proven to be more effective. In one of the monitored stands the effectiveness has not been demonstrated, because the operator has not logged in this forest cover enough m3 of the wood and the work was, therefore, loss making and time consuming. By the work of the woodcutters has the efficiency and shorter working times showed in two stands, where the measurement was carried out. Their productivity has been effective there, for example, with regard to the low number of trees and the larger crop density, the harvester technology would not be efficient.

Setting norms of consumption in the procurement operations department.
Millerová, Denisa ; Svobodová, Hana (advisor) ; Mejdrech, Vlastimil (referee)
The diploma thesis focuses on the problematics of setting the number of employees in the selected department (team) in a specific company. With respect to the severity of impact of this decision, the diploma thesis choses a sophisticated tool, norms of work consumption. To simplify their utilization a model is created to specify the number of employees. The basis for construction of the model is summarized in the theoretical-methodological part. Practical part of the diploma thesis presents the company, the department and the team and it defines preformed processes. Furthermore, it calculates (determines) individual elements needed for building the required model, namely the time normatives (norms) of the activities, probabilities of occurrence of certain activities and usable time fund of an employee. Lastly, the created model is tested by using real data from the last period and consequent recommendations are presented.
