Opis:: The purpose of the work presented here is a comparative analysis of two methods of solving the problem of optimizing the working time and path length of operators for manual harvesting of raspberries over an area of one hectare. An analytical solution is a method of solving mathematical problems based on finding an exact formula that describes a phenomenon or process. A simulation solution is the opposite of a numerical solution, which is based on calculating an approximation using statistical methods. An analytical and simulation approach will be presented to show how to calculate the number of workers needed, the minimum working time and the length of the path taken by raspberry fruit pickers. The results obtained for the two methods are compared.

Opis:: In Poland, the genus Rubus comprises 95 species. Given the commercial production of the fruits as well as their medicinal properties and apicultural and ornamental importance, raspberries are commonly cultivated plants of great economic value. Rubi idaei folium exhibits a wide spectrum of pharmacological activities. The aim of the present study was to determine the content of some bioactive compounds and compare the antioxidant activity in R. ideaus leaves. The highest and lowest content of chlorophyll was found in the ‘Laszka’ and ‘Glen Ample’ varieties, respectively. The content of total fat, carbohydrate, and total protein was 2.1%, 6.2%, and 20%, respectively. Saturated fatty acids were dominated by palmitic, arachidonic, tetracosanoic, and stearic acids. Omega 3, omega 6, and omega 9 acids were mainly represented by α-linolenic acid, linolenic acid, and oleic acid, respectively. The highest antioxidant activity was determined in the leaves of the ‘Radziejowa’ variety, and the lowest level was found for the ‘Glen Ample’ variety. The high antioxidant activity and the content of bioactive compounds indicate that raspberry leaves can be used as drinkable infusions or extracts applied as additives to some food products.
