A two-phase constrained Chaotic Bee Colony approach towards managing coopetition in supply chain

Abstract

Competitive models give superiority to maximize only the buyer's profit which does not satisfy all members in supply chain whereas Coordinative models give superiority to whole supply chain over buyer's profit. In this paper, we have considered coopetition in supply chain. The competition in one buyer — multiple suppliers system for the supplier selection process has been considered by applying mixed-integer nonlinear programming in first phase. On the other hand, the total cost of the supply chain is minimized rather than only the buyer's cost to implement cooperation. Artificial Bee Colony and Chaotic Bee Colony are used separately in the second phase as optimization technique. Finally, the proposed model is illustrated by a numerical example from literature. A better result is found for buyer's cost by applying the proposed two-phase method while it's giving comparable result for total supply chain cost.
