Batch sojourn time in polling systems on a circle
Tim Engels, Ivo Adan, Onno Boxma +1
In this paper, we analyze a polling system on a circle. Random batches of customers arrive at a circle, where each customer, independently, obtains a uniform location. A single ser…
Same-day or next-day? Transparent time-dependent shipment pricing for e-fulfillment
Uta Mohring, Melvin Drent, Ivo Adan +1
We develop a parsimonious model of an e-commerce fulfillment center that offers time-dependent shipment options and corresponding fees to utility-maximizing customers arriving acco…
Exact results for the order picking time distribution under return routing
Tim Engels, Ivo Adan, Onno Boxma +1
This paper derives exact expressions for the Laplace-Stieltjes transform of the order picking time in single- and 2-block warehouses. We consider manual warehouses that deploy retu…
A finite compensation procedure for a certain class of two-dimensional random walks
Ivo J. B. F. Adan, Ioannis Dimitriou
Motivated by queueing applications, we consider a certain class of two-dimensional random walks for which their invariant measure is written as a linear combination of a finite num…
An exact analysis and comparison of manual picker routing heuristics
Tim Engels, Ivo Adan, Onno Boxma +1
This paper presents exact derivations of the first two moments of the total picking time in a warehouse for four routing heuristics, under the assumption of random storage. The ana…
An M/M/c queue with queueing-time dependent service rates
Bernardo D'Auria, Ivo J. B. F. Adan, René Bekker +1
Recent studies indicate that in many situations service times are affected by the experienced queueing delay of the particular customer. This effect has been detected in different…
