Volume 42, Number 13 New General Continuous-Time State-Task Network Formulation for Short-Term Scheduling of Multipurpose Batch Plants. Christos T. Maravelias and Ignacio E. Grossmann* Page 3073. In Table C4, parameter gs ($/kg) of states R1, R2, and I1 (entries in the second, third, and fourth columns of the last row) are all zero (instead of 10, 15, 25, respectively). In Table C5, parameter BMIN of task RII (entry in the second column of the last row) is 40 (instead of 80) and the parameter β of RI2 (entry in the fifth row of the fifth column) is 0.4 (instead of 0.04). In Table C6, parameter δiHS of RII (entry in the seventh column of the last row) is 0.4 (instead of 0.2). In Table C9, the entry in the fifth column of the first row is S21 (instead of S12). Table C10 is as follows (corrections are in boldface): Table C10. Data for Example 4 (BMAX and BMIN in tons, r in h, β in h/ton of Batch) task
