چکیده :

In this paper we define a supply channel model considering disruption between distributor and wholesaler /retailer which means that whole orders cannot be prepared .Here demand considered as random variable which r percent of demand that is more than in hand inventory considered as back order and (1-r) percent will be lost sale so we can satisfy customers when we face with extra demands .To be closer to real world definition we also considered budget in hand and supplier capacity random variables with normal distribution and to control randomness of constraints ,a confidence coefficient (ɵ) has been considered . As in disruption we face with some empty spaces in warehouse that create extra costs, we define warehouse , variable and determine its value by denovo method. Here we solved a bi- objective model which maximize profit and fill rate with Lp metric method and by using contour curves sensitivity analysis have been done during examples.
