DNV GL Maros 9.03.01

Maros 9.3.1 is now able to handle bottlenecks. Previously, Maros has validated the production profile of all product streams against the design capacity of each node and its respective parallel blocks. This makes sense during the design-phase where analysts are planning to design an unconstrained production system. However, during the operational-phase, design is fixed which does not give flexibility to change the capacities. To overcome this challenge, the new feature will allow these bottlenecks to be simulated and analysed.

This is added to the features released in Maros 9.3: an alternative to the existing flow method, more stability and more usability features. The new flow solver is part of the initial implementation of optimisation methods in Maros. The solver is a Mixed Integer Linear Programming (MILP) type of a solver based on the revised simplex method. This method focuses on setting up an objective function which represents the target to be optimised. The objective function would typically refer to an export node which will be used as a reference for the flow calculation. Other nodes could be selected as part of the flow calculation – for example, the user could try to minimise the amount of gas flared by adding a minimisation function to the flare
