Linear programming and sensitivity analysis: An AI-based CAI on operations research

Linear Programming and Sensitivity analysis (LIPS) is a computer aided instruction software package. It is specifically designed as a supplement to Computer Science students taking up INTROPE classes. The main topics included are the several algebraic methods of solving linear problems. Discussion on Sensitivity analysis can also be found in the system. The analysis is limited to the following cases: changes in the right hand side, addition of new constraints, and changes in the objective function. LIPS uses AI representation schemes in modelling domain knowledge. The domain knowledge includes the decision points regarding lesson flow and drill sequencing
