Abstract
With the rise of a consciousness in warehousing sustainability, an increasing number of autonomous vehicle storage and retrieval systems (AVS/RS) is diffusing among automated warehouses. Moreover, manufacturers are offering the option of equipping machines with energy recovery systems. This study analyzed a deep-lane AVS/RS provided with an energy recovery system in order to make an energy evaluation for such a system. A simulator able to emulate the operation of the warehouse has been developed, including a travel-time and an energy model to consider the real operating characteristics of lifts, shuttles and satellites. Referring to a single command cycle with a basic storing and picking algorithm for multiple-depth channels, energy balance and recovery measurements have been presented and compared to those of a traditional crane-based system. Results show significant savings in energy consumption with the use of a deep-lane AVS/RS.
Highlights
In recent years, an increasing consciousness in sustainable warehousing and energy efficient operations in warehousing has come about, due to both the growing of green awareness and energy resource scarcity [1]
Each satellite is charged when attached to its shuttle, so it is not involved in the calculation of the installed power
For each run of the simulation, energy consumption and energy recovery performances have been computed in order to evaluate energy sustainability of the system
Summary
An increasing consciousness in sustainable warehousing and energy efficient operations in warehousing has come about, due to both the growing of green awareness and energy resource scarcity [1]. The interest shown by companies on issues related to sustainability in logistics is highlighted by the increasing number of works on lean and green logistics [2] This trend has been especially verified with regards to Automated Storage and Retrieval Systems (AS/RS) [3,4], where energy saving, both in terms of energy efficiency and reduction of carbon dioxide emissions, has become one of the most significant performances to be achieved within a sustainable perspective [5]. Recent studies show that the traditional time-based perspective has been overcome by the importance of sustainable and energy efficient operations in material handling processes [6].
