The impact of stochastic lead times on the bullwhip effect – an empirical insight

Nielsen P., Michna Z.

Management and Production Engineering Review

2018

Vol. 9, No. 1

65--70

In this article, we review the research state of the bullwhip effect in supply chains with stochastic lead times. We analyze problems arising in a supply chain when lead times are not deterministic. Using real data from a supply chain, we confirm that lead times are stochastic and can be modeled by a sequence of independent identically distributed random variables. This underlines the need to further study supply chains with stochastic lead times and model the behavior of such chains.

Lead times - their behavior and the impact on planning and control in supply chains

Nielsen P., Michna Z., Sørensen B. B., Dung N. D. A.

Management and Production Engineering Review

2017

Vol. 8, No. 2

30--40

Lead times and their nature have received limited interest in literature despite their large impact on the performance and the management of supply chains. This paper presents a method and a case implementation of the same, to establish the behavior of real lead times in supply chains. The paper explores the behavior of lead times and illustrates how in one particular case they can and should be considered to be independent and identically distributed (i.i.d.). The conclusion is also that the stochastic nature of the lead times contributes more to lead time demand variance than demand variance.
