making it easier to comprehend how the model is structured, how it can be changed, and how results can be interpreted. If a network structure is embedded in a linear program, the problem is a network ...

On the basis of forecast consumption, a linear-programming model can yield a plan for optimal flow rate of a gas pipeline. The compressibility of natural gas allows the use of line pack to ...

This paper focuses on multi-objective diet models in Class 2a. For completeness, Class 2b is discussed in Supplementary Appendix A. All references mentioned in Class 2 use linear goal programming ...
