Process Flexibility Design in Unbalanced Networks

Abstract: Several design guidelines and flexibility indices have been developed in the literature to inform the design of flexible production networks. In this paper, we propose additional flexibility design guidelines for unbalanced networks, where the numbers of plants and products are not equal, by refining the well-known Chaining Guidelines. We study symmetric networks, where all plants have the same capacity and product demands are independent and identically distributed, and focus mainly on the case where each pro… Show more

“…The constraint (13)- (15)guarantees that the solution is an inscribed sphere of the intersection of Ω ξ (x) and [λ 1 , λ 2 ] WN . The above LP shares almost the same structure as our lower bound model (9), which implies that a similar result as Theorem 1 can be shown. Considering the space limitation, we omit the detailed discussion here.…”

“…Let x * be the optimal solution of the exact model (2), and let SL * be the corresponding optimal joint service level. Let y • be the optimal solution to the lower bound model (9). From our discussion in Section 3.1, y • corresponds to a feasible capacity investment solution that is feasible to the exact model (2), in which we denote its service level by SL • .…”
