Variance-based approximations of transaction waiting times in autonomous vehicle storage and retrieval systems

Zhang, Li; Krishnamurthy, Ananth; Malmborg, Charles J.; … - In: European Journal of Industrial Engineering 3 (2009) 2, pp. 146-169

Approximation strategies for transaction waiting times are proposed for use in Autonomous Vehicle Storage and Retrieval Systems (AVS/RSs) with non-Poisson arrival rates and non-exponential service times. The proposed modelling tools dynamically adjust approximations based on the variance of the...

Performance modelling of autonomous vehicle storage and retrieval systems with generally distributed service times

Zhang, Li; Krishnamurthy, Ananth; Malmborg, Charles J.; … - In: European Journal of Industrial Engineering 5 (2011) 4, pp. 448-470

This paper proposes extensions of system conceptualisation models for autonomous vehicle storage and retrieval systems (AVS/RSs) to deal with non-exponential lift service times when the number of lifts and vehicles are both design variables. These extensions are based on an adaptation of a...
