“…The planning horizon is assumed to cover a set of period t∈ (0, 1, 2… T). Along this horizon disruption may occur and reconfiguration decisions are made only in the planning periods td t ∈ T. This disruption reconfiguration planning periods are assumed to be three periods following the works of Hendricks & Singhal, (2005), Losada et al, (2010Losada et al, ( , 2012, Sahebjamnia et al, (2015) and Torabi et al, (2015). The first period within reconfiguration planning horizon when disruption occurs is termed as 'onset period' and the remaining two periods are termed as 'recovery periods' as shown in figure 1.As our problem is long term strategic in nature where each period may represent one or more years, inventory decisions do not provide representative information and are not considered in the model i.e.…”
