چکیده:
In this paper, we develop an integrated bi-objective model of a two-stage supply chain composed of a vendor and a buyer under an imperfect production process. In the stochastic inflationary condition the first objective is to minimize the expected costs of the proposed supply chain model and the second objective is to minimize buyer’s shortage variance. We assume lead time and ordering cost are controllable parameters and lead time crashing cost is considered as a function of both order quantity and reduced lead time. An effective solution procedure is developed to determine the optimal policy of the proposed model. Finally, a numerical example and sensitivity analysis are proposed to show the performance of the model.

Later, Pan and Hsiao (2005) proposed an integrated inventory model with backorder price discount and controllable lead time wherein lead time crashing cost is a function of both ordering quantities and reduced lead time.
Glock (2012) considered a single-vendor single-buyer inventory model with lot-size-dependent lead time and lead time reduction and assumed vendor’s set up cost can be decreased with an extra crash cost with a piece-wise linear function.
Therefore, based on the above-mentioned conditions, we extend the previous research by proposing an inflationary bi- objective integrated vendor-buyer inventory model with stochastic demand and controllable lead time and ordering cost in which allowable shortage is a mixture of backorder and lost sale.
We first minimize the joint expected annual cost as a main objective when ordering cost, ordering quantity, reorder point, number of shipment and lead time are the decision variables, and then reduce shortage variance as a second objective.
