Integrated operational supply chain planning in Industry 4.0

The scenario of isolated companies competing with each other has evolved to a holistic vision, where companies collaborate and work together to maintain supply chain competitiveness. Integrated supply chain planning, although challenging, is necessary to foster competitive advantage and to ensure companies' survival in difficult times. Concepts and technologies introduced by the Fourth Industrial Revolution support such integrated planning models. This paper presents a systematic literature review on integrated supply chain planning aiming to identify research streams, opportunities and the impact of Industry 4.0. The study identified the lack of research on supply chain planning which considers Industry 4.0 concepts and opportunities. Five prevailing research streams stand out: 1) approaches to deal with complexity; 2) the consideration of uncertainty; 3) raw material inventory control and procurement processes; 4) the necessity of considering environmental impacts; 5) particular models for dealing with limited lifetime products. Finally, the following future research opportunities were identified: 1) improving decision-making models to consider stochastic and dynamic behaviours; 2) extending the models to include larger networks with more variables; 3) developing more efficient solving approaches.
