Abstract Makespan minimization or throughput maximization, the most common objectives in batch process scheduling are related to economical aspects; energy consumption or sustainability are not directly taken into account ( Mendez et al., 2006; Hegyhati and Friedler, 2010 ). Some of the published methods consider utility cost ( Adonyi et al., 2003 ) or wastewater minimization (Halim and Srinivasan, 2010) during the optimization in addition to economical aspects, nevertheless, the overall energy requirements of a process have never been taken into account. In the present work, a scheduling method is proposed that also considers the energy demands of transfer of liquid materials. In the available mathematical models, transfer of intermediate materials has impact only on the overall processing time, and does not express the energy consumption of the transfer. Transfer time of intermediate materials is usually regarded as a fixed value, however, there is an energy –time tradeoff for pumping of intermediate, raw, or product materials. The energy cost of transfer depends on the height difference between the source and destination, the cross-section area of the pipe, viscosity of the material, and the available time. The proposed method integrates pumping strategies into the general scheduling problem to tackle the transfer energy demands. Although this energy is much smaller in magnitude compared to the usual heat energy requirements, still, it is worth investing effort in its reduction, since it is in the form of electrical energy.
