Logistics and Transportation

We're very aware of the social and financial worth of communication and logistics in society and the world. That's why Slefty never neglects our quality and correction standards for your project's analysis and execution.

We have what you need
  • Warehouse Design

    Designing a warehouse is much more than designing a storage volume. The form, space and equipment must be synchronized so that the building's operation is smooth and free of over costs. Slefty is able to contribute with:


    • Viability Study
    • Layout Design
    • Civil Engineerin Design
    • Building Services Engineering
    • Performance Design and Specifications
  • Traffic engineering

    Road networks in urban environments are highly impactful for the local population. Don't build yours before making sure they'll result in user satisfaction, with the least risk of complaint. Consult Slefty's solutions to arrange your efforts the best possible way. We can contribute with:


    • Create scenarios in urban environment to know today the outcomes of future changes
    • Predict congestions and create solutions for them
    • Analyse people and vehicles flow
    • Smart Cities flow control implementation
    • Analytics and data gathering
  • Warehouse Simulation

    From the layout design to the operation, warehouse simulation provides important dynamic information for decision making and optimization within a logistics warehouse. Nothing better than using a computational tool to predict what happens in your warehouse without making real experiences. The simulation can thus contribute to:


    • Reduce and avoid queues from trucks to employees
    • Optimize layout to reduce transportation times and conflits
    • People and materials occupacy levels
    • Balance capacity between floor space, people, machines and docks
    • Obtain KPI's for future scenarios
