The optimal scheduling of crude-oil operations in refineries has been studied by various groups during the past decade leading to different mixed integer linear programming (MILP) or mixed integer nonlinear programming (MINLP) formulations. This paper presents a new continuous-time formulation, called single-operation sequencing (SOS) model, which can be(More)
During the last 15 years, many mathematical models have been developed in order to solve process operation scheduling problems, using discrete or continuous time representations. In this paper, we present a unified representation and modeling approach for process scheduling problems. Four different time representations are presented, compared, and applied(More)
The aim of this paper is to introduce a methodology to solve a large-scale mixed integer nonlinear program (MINLP) integrating the two main optimization problems appearing in the oil refining industry: refinery planning and crude-oil operations scheduling. The proposed approach consists of using Lagrangian decomposition to efficiently integrate both(More)
Statistical asteroid-orbit-computation methods have proved to be important in problems such as computing the collision probability [1], performing dynamical classification, identifying asteroids [3], and aiding the recovery of lost objects. These methods will be of major importance during the Gaia mission (to be launched in 2012). Here we present novel(More)
