Abstract: Considering the demand of energy consumption and inventory in refinery production schedule ，on account of a
refinery practical situation ， the global model which includes four process units such as atmospheric vacuum distillation ，
catalytic cracker ， solvent oil equipment and gas separation equipment were established ． The objective function of the
optimization is to maximize the profits of the whole refinery ． The decision variables are every output of the product ． The
constraints in the optimization include mass balance ， equipment processing and quality demand ． The energy consumption
constraint and inventory constraint with integral form was presented ．Transforming the model to nonlinear programming and
solving it by matrix least square method ，an example in the end proves the validity of this model ．

Key words: Refinery schedule , Production － inventory optimization , Compromise programming , Least square method
