A programação de operações como instrumento de melhoria na interface operacional: um estudo de caso na empresa Vale

Abstract

Rail transport is consolidating more and more as a powerful instrument of national economic development, where the railways are increasingly challenged to provide quality services at competitive prices. For this programming operations should serve as a tool for operational improvement, since problems of railway scheduling resources are of great complexity. Aimed at reconciling demand and time scheduling an operation can be understood as a detailed timeline that shows when the work should begin and when they should end. The research aims to develop a graphical programming tool in production that can increase operational integration between rail and loading terminal of the company's North Valley system. From a case study of an applied nature of the research focuses on a quantitative and qualitative analysis of exploratory and descriptive nature. A trade-off analysis between operational indicators of the loading process is performed in order to confirm that the application of this tool is able to meet the objective of the research
