The compressibility of natural gas allows the use of line pack to compensate for fluctuations of gas demand. On the basis of forecast consumption, a linear-programming model can ...

Advantages of Network Models over LP Models Many linear programming problems have large embedded network structures. Such problems often result when modeling manufacturing processes, transportation or ...

We present a novel linear program for the approximation of the dynamic programming cost-to-go function in high-dimensional stochastic control problems. LP approaches to approximate DP have typically ...

1. Formulate an LP model for this problem 2. Create a spreadsheet model for this problem and solve it using solver 3. What is the optimal solution 4.

We use the models of cognitive psychology and the early literature on linear programming models to understand how experts organize their thinking about models. We show that several different patterns ...

An operations planning and economics improvement project at ConocoPhillips's Lake Charles, La., refinery successfully developed and implemented high-quality kinetic process models used for unit ...
