Ostrohliad O. Enhancing the effectiveness of the function of the part handling-and-storage system of the metallurgical enterprise industrial level based on logistic principles

The thesis is dedicated to solving a scientific problem of the enhancement of the effectiveness of the part handling-and-storage system of the metallurgical enterprise industrial level through the perfection of a logistical management of the process associated with execution of cargo operations, taking into consideration the influence of the external factors. We have reviewed the logistic part handling-and-storage system of the industrial level from the aspect of a system analysis. As a result, we have highlighted its principal subsystems, such as the logistical unloading part handling-and-storage system and the logistical shipment part handling-and-storage system, which are closely interrelated. Moreover, we have developed a method of a prompt adjustment of the plan of distribution of the cargoes coming into the metallurgical enterprise. The plan allows more effectively organising the function of the cargo fields of operations of an industrial enterprise in a cold period of year. In addition, we have offered an approach on a way of formalization of a dynamical transport problem in circumstances of division of the carriages into the field of loading, which is a kind of division providing a solution of the transport problem in blocks for each package of supplies. It takes into account the possibilities of the cargo field at the moment of arrival of each supply. Therefore, we have developed a simulated model of the logistical part handling-and-storage system of unloading of a raw material in circumstances of a change of temperature modes. The model offered by us allows perfecting the operation of the part handling-and-storage processes of the metallurgical enterprise, identifying a rational quantity of resources. Based on the experiments done by others, we have chosen the most sufficient mode of the logistic shipment part handling-and-storage system function. Besides, we have designed a simulated model of the logistical loading part handling-and-storage system allowing us to set a reasonable division of auto transport between the most intensive fields of shipment of finished products, taking into account a railway transport. The results of the completed researches allowed us to increase the effectiveness of the operation of the part handling-and-storage system of the metallurgical enterprises thanks to decreasing the expenditures associated with its function through reduction of the duration of the idle standing of the vehicles in circumstances of an abrupt alteration of the air temperature and estimation of a reasonable quantity of used transport and auxiliary resources.
