Обоснование выбора технологии перегрузочных работ с учетом особенностей функционирования объекта
The development of the domestic economy from the beginning of the 21st century is characterized by the growth of energy resources export volumes, including coal. That circumstance determined the increased demand for the design, research and modernization of export bulk cargo terminals. Growth of customers requirements and outdated standards, regulations and specifications define the need to improve design’ quality. An article covers issue of justification of material handling technology in the stockyard area of the export bulk cargo terminal within organizational and technical design. These terminals have a large throughput capacity and a unidirectional material flow which determine their narrow specialization and increased demands of ensuring reliability for terminals’ functioning. Providing of material handling technology in the stockyard area based on using specialized high-performance equipments with stream-flow transportation – stackers and reclaimers, as well as their combined type – stacker-reclaimers. That circumstance defined appropriateness of the problem research of equipment selection type (separate or combined) taking into account special aspects. To solve this problem, we used simulation methods that allowed to create a simulation model of the stockyard area functioning and to carry out experiments of parameters variation. The results allowed to estimate the range of incoming and outgoing flow intensity, which determines preference of choosing schemes with separate or combined equipment’ type. A formalized selection process by using the qualimetry methods based on a system of criteria was offered in reason of accounting special aspects of functioning within justification of the most effective material handling technology with increased accuracy. Mathematical tool, which used in proposed selection procedure, allows to taking into account many parameters, including qualitative characteristics, in spite of difficulty to present them in concrete values form. Thus, accounting special aspects of functioning becomes possible, which in general allows to substantiate the most effective material handling technology.
