Simulação aplicada ao processo produtivo da Associação de Agentes Ecológicos de Dourados (AGECOLD)

Abstract

Given the large volume of recyclable solid waste generated daily and their disposability - both after-sale and post-consumer - without treatment in dumps, selective collection associations play an important role in the context of reverse logistics. The present work has the objective of developing a model of discrete event simulation that allows to study alternative scenarios to improve the production of a selective collection association of Dourados -MS, in order to contribute with the managers of the association to a systemic view of the effects that the changes will bring and subsidize the decision making through a dynamic analysis of the productive flow. For this, quantitative modeling - elaborated using the Arena® software - was used to analyze the results of the scenarios and support decisions. Thus, satisfactory results were obtained in the step of sorting the materials on the treadmill by increasing 1 employee and by 15% the material inputs, reducing press idleness and consequent increase of 20% of the quantities produced. already in the cardboard pressing stage, alternative models were modeled with 2 presses in operation, and with 1 employee occupying the rest hours, the results indicated an increase in the number of bales processed in one month by 50.3% and 44, 38%, reduction of unprocessed bundles by 94.16% and 95.26%, and the reduction of queuing time to be processed of 95.26% and 88.66%; respectively. In addition, the scenarios created for the cardboard remove the overload of the press, causing it to work within its capacity, which is 100%, wi th a percentage of 99%, since in the current scenario the press works 41% above its capacity total. Finally, the sales of the paper was verified with the entry of the proposed scenarios with an increase of R $ 9187.5 for 1 employee occupying the rest hours and R $ 10412.5 with 2 presses in operation.
