In the paper on hand, we give a detailed problem description and model the problem as a binary linear programme.
Process variables are optimized simultaneously with the plant structure by formulating the whole optimization problem as a non linear programme (NLP).
"It's really just a linear program".
We also show that the codon-scrambling problem is analogous to the well-known travelling salesman problem, and obtain an exact solution to it by using De Bruijn graphs and a modern mixed integer linear programme solver.
Among others, the optimisation task has been formulated as integer linear programme [5, 6], network flow programme [7 10], quadratic Boolean programme [11], energy minimisation [12, 13], generalised clique graphs [14, 15] and maximum weight-independent set problem [16].
Finally, DEA model is designed and resolved as standard linear programme.
They include econometric [ 41, 42] to linear programme models [ 38, 40, 43] and alternatives such as systems dynamics and stochastic models which take account of uncertainty [ 30, 44].
CVaR is minimized using linear programmes, while a multiobjective genetic algorithm is designed for minimizing VaR, considering two scenarios for each currency.
The proposed site layout problem with multiple construction stages is formulated as a binary-mixed-integer-linear programme, which can be solved by a standard branch-and-bound algorithm using the commercial software package LINGO.
This is because i) active-set methods are usually the fastest ones for quadratic and linear programmes of small and median size; and ii) expensive computations, like solving systems of linear equations, can be shared in the active-set method.
