SOFTWARE
Simulink Design OptimizationSimulink Design Optimization™ provides interactive tools, functions, and Simulink® blocks for estimating and tuning Simulink model parameters using numerical optimization. An interactive tool lets you automatically estimate model parameters such as friction and aerodynamic coefficients from test data to increase model accuracy. You can preprocess test data, select model parameters to estimate, start an optimization, and validate estimation results.

1. INTRODUCTION1.1 SYSTEMS APPROACH A critical element of sustainable economic development
(Planning, management and desIgn) To critically analyze the true economic costs, benefits and
environmental consequences of projects Systems analysis involves the construction and linkage of
mathematical models of the physical and economic subsystems associated with resource allocation systems
Most systems models are based on statements of basic conservation laws (mass, energy, and momentum), but they can also be empirical or statistical.
Systems analysis models are generally broken down into two categories: simulation models and optimization models.

1.2 SIMULATION AND OPTIMIZATION MODELS
Simulation models are used to predict a system’s response to a given design configuration with great accuracy and detail, and to identify the probable costs, benefits, and impacts of a project (predicts the outcome of a single, specified set of design or policy variables)
Optimization models provide a means of reducing the number of alternatives which need to be simulated in detail, i.e., screening them. Optimization models are generally used for preliminary evaluation or screening of alternatives and to identify important data needs prior to
extensive data collection and simulation modeling activities.
1.3 Model Building Process The process of developing the mathematical simulation and
optimization models which represent the system under investigation consists of several steps :
1. The first step, problem identification2. a general outline and purpose of the model must be
established3. The analyst will need to identify the appropriate type of
model for the system4. In the next step, conceptualization and development
(appropriate computational techniques are also determined and implemented for the problem)
5. Calibration of the mathematical model is then performed to determine reliable estimates of the model parameters
