With three dimensional finite element method, the author analysed and calculated the stress of the dam section with erecting bay in the Zuojiang water resources pivotal project.

Single machine group scheduling with resources dependent setup time;

The objective function is to minimize total resource consumption of setup time and jobs under makespan constrains.

In this model, the setup time of a group is a strictly decreasing function of the amount of resources consumed, and the processing time of a job is a strictly increasing linear function of its starting time.

Single machine group scheduling problem with setup times;
