Proposta de sequenciamento e alocação de tarefas em um contexto de máquinas paralelas idênticas para a minimização do uso de solventes químicos: estudo de caso

Abstract

Chemical solvents have many uses in the industrial environment, especially the coating industry. In this medium has as common use the aid in the dilution of resins and for cleaning production from one batch to another. In this medium has as common use the aid in the dilution of resins and cleaning production from one batch to another, with some solvents being combatable with the other or not, so the order of which product to produce first becomes extremely important for the companies. definitions of equipment cleaning costs. Thus, this work proposes, using Lingo software, to use exact methods in order to contribute to an option to reduce the use of chemical solvents in a parallel machine environment. After a 50hour computational implementation, peertopeer compatibility results were achieved from 32 (actual data) to 83 times (simulation result), an increase of 160%, as well as reducing the average between total production times. from 698.14 to 622.00 minutes, providing a reduction of 12.2%. Therefore, the solution method used was able to expose a new option of sequencing and allocation of activities in the machines of a chemical industrial production that offers a reduction on the use of solvents as well as the cost.
