A technique for determining the optimum mix of logistics service providers of a make-to-order supply chain by formulating and solving a constrained nonlinear cost optimization problem
In this paper, a technique has been developed to determine the optimum mix of logistic service providers of a make-to-order (MTO) supply chain.A serial MTO supply chain with different stages/ processes has been considered.For each stage different logistic service providers with different mean processing lead times, but same lead time variances are
