DISCRETE EVENT SIMULATION INTEGRATED WITH VALUE STREAM MAPPING AS A TOOL FOR SUSTAINABLE INNOVATION IN THE PUBLIC SECTOR.

This paper presents a proposal for integration between Discrete Event Simulation (SED) and Value Stream Mapping (VSM) with the objective of promoting sustainable improvements in administrative processes of a federal public institution, from the perspective of a Lean Public Administration (EPA) and aligned with the Sustainable Development Goals (SDGs). The case study was carried out in a sector responsible for the settlement of invoices, whose projected demand of 160 monthly invoices had not been met. From the modeling of the current process and the simulation of a future state based on lean principles and digitization of documents, a 15% reduction in lead time and the complete fulfillment of the projected demand was observed. The results demonstrate the potential of the integrated approach between SED and VSM as an innovative practice in search of operational efficiency and sustainability in the public sector.
