BlueM.Opt Usage

BlueM.Opt | Usage | Development

Demonstration videos

• Basics: demonstration using a mathematical test case
• Simulation-based optimization: demonstration using a simulation model
• SensiPlot: demonstration of sensitivity analysis
• Hybrid: demonstration of simultaneous optimization of both continuous and nominally discrete variables

Quickstart

1. Start BlueM.Opt.exe
2. Select an App (e.g. BlueM.Sim)
3. Select an appropriate Dataset
4. Select a Method (algorithm) (e.g. PES or SensiPlot)
5. optionally adjust or load the settings
6. Press the Start button

Notes

Dataset locations and simulation results

BlueM.Opt creates copies of the dataset for carrying out the simulations. These copies are located in the directory containing BlueM.Opt.exe and are called Thread_01, Thread_02, etc. Once the objective function values have been calculated, the dataset together with the simulation results in these folders are deleted/overwritten.

In order to view hydrographs and/or obtain the full simulation results of specific solutions, select a solution by clicking on it in any of the diagrams and then click the button in the Selected solutions dialog. This will cause the selected solution(s) to be simulated again, but this time in a subfolder of the original dataset named "solution_X", where X is the solution ID.

When using SensiPlot, the setting Save individual datasets causes each indivual datasets to be simulated in a subfolder of the original dataset named "sensiplot_X", where X is the solution ID. If the aforementioned setting is deactivated, the dataset modifications and simulations are carried out using the original dataset.

Microsoft.ACE.OLEDB.12.0 Provider

BlueM.Opt stores optimization results in a MS Access database. This requires a corresponding driver to be installed on the machine. If you have Microsoft Office installed, this driver is usually already installed. However, if you have the 32bit version of Office installed, you will have to additionally install the x64-version of the driver for BlueM.Opt, which is a x64 program, to work.

A missing driver will result in the following or similar error message when setting the method:

The Microsoft.ACE.OLEDB.12.0 Provider is not registered on the local machine

Der Microsoft.ACE.OLEDB.12.0 Provider ist nicht auf dem lokalen Computer registriert

To fix this, download and install AccessDatabaseEngine_X64.exe from here: https://www.microsoft.com/en-US/download/details.aspx?id=13255
