The modeling idea is sound, but it needs 9-dimensional z-variables instead of the 8-dimensional variables defined in notations 24.1. Examples of the correct model (with 9-index variables) are: (1) Diaby, M., "Linear Programming Formulation of the Set Partitioning Problem," International ...
Despite many algorithmic developments, the solution of integer linear programs may still carry a substantial computational cost. Recent research has made it apparent that the user of ILP software may be able to reduce this cost by paying careful attention to the formulation of the ILP model. Here...
This paper demonstrates how to overcome this inadequacy by formulating the problem as a multi-component Markovian decision process and then solving it as an associated linear programming model. The proposed methodology is illustrated by using a simple, but realistic, example for determining the optimal...

While the AC-OPF is a non-linear programming problem, this can be transformed into a mixed-integer linear programming environment by the proposed model without loss of accuracy. The global optimality of the solution for the approximated model can be guaranteed by existing algorithms and software. ...
