Operations is hoping for a deservedly long operating cycle, but the refinery linear programming (LP) model is predicting significant current profits if the unit is operated to push constraints. What ...

An operations planning and economics improvement project at ConocoPhillips's Lake Charles, La., refinery successfully developed and implemented high-quality kinetic process models used for unit ...

The feasibility pump is a well-established primal heuristic for mixed integer programming (MIP) that alternates between solving a linear programming (LP) relaxation of the original problem and ...
