Abstract: This paper addresses the crude oil procurement planning problem in distributed multiple supplier/refinery supply chain,and develops under constraints of limited resources An optimal JIT procurement model to minimize the total costs and cycle time Subsequently,the non-linear programming model is transformed into a linear programming one,which is further solved by a hybrid of the Analytical Hierarchy Process and the multiple objective programming approach Finally,numerical computations demonstrate that the approach proposed for curde oil procurement planning is efficient and applicable.

Key words: supply chain, procurement optimization, just in time, multiple objective programming, analytic hierarchy process
