OPTIMIZATION OF PLANT INTERNAL TRANSPORTATION ACCORDING TO THE CONTACT SCHEDULE

Abstract

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The presented article is a continuation of research on development of an alternative model for organization of transportation according to the contact schedule i n the conditions of a metallurgical enterprise. The mathematical model is based on a dynamic transport problem with delays (DTPD). It is shown in what way an optimal transportation plan is obtained and minimization of transportation costs is ensured with the agreed production programs of supply shops and consumer shops. The improvement of the system of transportation of empty cargo flow according to the contact schedule with the help of DTPD, as the authors argue, allows to abandon the strict assignment of cars to a specific transportation, supply of empty cars is carried out according to the most favorable option for a consumer (with a minimum of transport and production costs). The cars can be delivered to the consumer for loading onto the cargo front from under any used load. The use of a dynamic transportation problem with delays as the basis of a mathematical model for development of an optimal plan for transportation of cars according to the contact schedule helps to more than halve the transport and production costs of the shops of the metallurgical plant.
