M3O-Multi-Objective-Optimal-Operations

M3O is a Matlab toolbox for designing the optimal operations of multipurpose water reservoir systems. M3O allows users to design Pareto optimal (or approximate) operating policies for managing water reservoir systems through several alternative state-of-the-art methods. Version 1.0 of M3O includes Deterministic and Stochastic Dynamic Programming, Implicit Stochastic Optimization, Sampling Stochastic Dynamic Programming, fitted Q-iteration, Evolutionary Multi-Objective Direct Policy Search, and Model Predictive Control. The toolbox is designed to be accessible to practitioners, researchers, and students, and to provide a fully commented and customizable code for more experienced users.

List of methods available

- Deterministic Dynamic Programming (DDP);
- Stochastic Dynamic Programming (SDP);
- Implicit Stochastic Optimization (ISO);
- Sampling Stochastic Dynamic Programming (SSDP);
- Evolutionary Multi-Objective Direct Policy Search (EMODPS);
- Fitted Q-Iteration (FQI);
- Model Predictive Control (MPC);

How to handle <filename>.mex files in MATLAB

M3O uses some <filename>.mex files built from the associated <filename>.c files (i.e., nakeinterp1mx.c and rtenslearn_c.c) which are used to speed up the computation efficiency.

To build up the .mex files from <filename>.c, run mex -v <filename>.c in MATLAB. If MATLAB cannot find a valid compiler, then you may need to install one on your machine by following this link.

Simlake test case and sys_param

M3O comes with a test-case using synthesized data to demonstrate the value of each algorithms. To run the test case, simple run main_test.m in MATLAB. A global structure variable sys_param is shared by the inner functions of the toolbox via the global command. Under the sys_param there are two subfields, namely the ‘.simulation’ which holds generic settings for running the dynamic simulation of supplied case study, and .algorithm which holds the specific algorithmic settings for each algorithm. For more details see the HELP FILE.

Libraries

M3O relies on external code in the lib directory, including the rtree-c code by P. Geurts for the implementation of the Extremely Randomized Trees (Extra-Trees), SLMtools by John D’Errico, and NSGAII implementation by Aravind Seshadri.
