O processo logístico, como o conhecemos atualmente, apresenta algumas limitações, pois tem-se revelado ineficiente e insustentável. Efetivamente, a inexistência de partilha de recursos e a dificuldade de implementar melhorias, tornam o serviço deficitário. Como exemplo desta ineficiência, verifica-se que, a quantidade de viagens efetuadas sem ou com pequenas cargas representam uma percentagem significativa das viagens efetuadas. Partindo deste paradigma surgiu um novo modelo logístico, a Physical Internet (PI). Este modelo pressupõe a utilização de uma rede logística global aberta, que permita a partilha de informação e de meios. A PI utiliza caixas modulares padronizadas, que são a base da transformação logística. Assim sendo, com este trabalho analisou-se a eficiência de uma das componentes da PI, nomeadamente o impacto que as caixas modulares padronizadas poderão ter nos problemas de carga de camiões, conhecidos na literatura como “container loading problem” (CLP). Este trabalho permitiu verificar que os tempos de processamento dos problemas logísticos, recorrendo à utilização das caixas da PI, é significativamente inferior. Principalmente à medida que o volume ocupado pelas caixas é mais próximo do volume do contentor.
Logistics, as we know it today, has shown some limitations, as it proven to be inefficient and unsustainable. Actually, there’s a lack of resource sharing and a struggle to implement changes that make it deficient. As an example, there is a significant part of the trips that are made with empty or almost empty loads. With this paradigm in mind, a new model emerged, the Physical Internet (PI). This model uses an open global logistics network that allows that information and resources could be shared. PI uses standard modular boxes that are the key for the logistics change. This work looks at the efficiency of one part of the PI, in particular, the influence of standard modular boxes in the Container Loading Problem (CLP). Whit this work it was possible to prove that the processing time of the problems using the PI is significantly shorter. Especially when the volume occupied by the boxes comes close to the container volume.
