Abstract

The paper presents some results of optimization calculations for a cotton harvesting and transportation system to be implemented in the Syrian Arab Republic. The authors have determined that with account of the performance of the harvesters used and the harvesting time limitations, two cotton harvesters of the KhMP-1.8 brand (JSC Gomselmash, the Republic of Belarus) are required to get harvest from an area of 100 hectares. Gven a transportation distance of the cotton yield to its temporary storage site of 0.5...1 km, the ratio of machinery means will equal 2: 4 (two combine harvesters per four tractors: Al-Furat E470 tractor with a power capacity of 51.5 kW (the Syrian Arab Republic) with a Palazoglu i2-4 trailer (Turkey). For a transportation distance of 1.5...3 km the ratio will equal 2:5, while for 5 km - 2:6. In case of a transportation distance of 12 km, the ratio between combine harvesters and transportation vehicles amounts to 2:9. For distances of more than 14 km, a diagram of the functional dependence of the number of transportation vehicles calculated for a fixed number of combine harvesters by the criterion of optimality - the minimum of costs from mutual expectation - does not have an extremum even at a ratio of 2:10 and takes the form of an asymptote. In order to obtain an extremum, it is necessary to introduce additional vehicles, which is inexpedient; or make use of other more productive types of vehicles. For example, in most provinces of the Syrian Arab Republic, there are no off-road vehicles capable of travelling across plowed (cultivated) fields.
