Modelo de Reprogramação de Produção em Flow Shop Híbrido Unidirecional Integrando Fabricante por Contrato e seus Clientes

Abstract

Contract Manufacturers (CMs) usually schedule their production considering the requirements and constraints of each purchasing industry separately. This strategy limits the quality of production rescheduling due to difficulties in evaluating capacity utilization opportunities and the need to renegotiate delivery commitments. This research aims to propose a novel unidirectional hybrid flow shop rescheduling model to address the integration of a contract manufacturer, responsible for production execution and inventory control, and its industrial customers, who manage delivery planning. The study was structured in three phases: identifying research gaps and opportunities, developing the conceptual model, and modeling a real hybrid flow shop using a multi-method approach. The results highlight the model’s potential to improve production execution and delivery performance, enhance partnerships among stakeholders, and reduce the need for renegotiation.
