The scheduling framework is based on the Resource-Task Network, with the objective function that represents the profit taking into account the net income from production and water-related costs. Because of the bilinear terms appearing in the mass balance equations, the overall formulation is a mixed-integer nonlinear program, which is generally more difficult to solve than a mixed-integer linear program or a nonlinear program. A solution strategy that involves relaxation linearization is therefore developed to facilitate the computation. Two literature examples are used to illustrate the proposed approach. ? 2010 American Chemical Society.[SDGs]SDG6journal article10.1021/ie10075362-s2.0-79953323055https://www.scopus.com/inward/record.uri?eid=2-s2.0-79953323055&doi=10.1021%2fie1007536&partnerID=40&md5=102da4c227a9a4ce2373fe201ede2b32
