What is the difference between optimization and simulation

According to Chong and Zak , optimization theory and methods deal with selecting the best alternative in the sense of the given objective function. In optimization, it only produces one solution. One of the application of optimization is in budgeting, where users want to minimizing cost or maximizing utility. Whereas simulation is using model numerically to enter the desired input so that it can show how the input affect the output of the system Law and Kelton, The application area is numerous, some of them are to design and analyze manufacture system, to evaluate military system or tactic, to decide order policy, to analyze financial or economic system, etc.

Both methods have their own advantages and disadvantages compared to the other. Optimization offer high quality analytical solutions and powerful tactical and strategic applications, whereas simulation has the advantages by offers practical scenarios with minimal assumptions and also offer the ease to manage parameter of uncertainty to produces a long term strategy.

Data simulation tools are used in businesses of all sizes and in all industries to analyze current processes and determine where to focus on improvements. Here are some simulation system examples :. Simulation modeling requires keen observation and data analysis—in some cases, large amounts of data—to get an accurate picture of the system.

Simulation and optimization can therefore be seen as two complementary approaches to solving business problems.

Optimization is used more often to determine an optimal system design. Constraints : Successful optimization depends on properly identifying the constraints placed on various parameters—for example, a business might have a maximum number of employees it can hire to work on production lines. With simulation, the analyst starts with realistic values for inputs and modifies them within reasonable ranges to determine what happens with the outputs. This variability can make a large difference in the accuracy of the results.

This is one of the advantages of optimization. Simulation, by contrast, is considered more exploratory. We offer a suite of supply chain planning, network optimization, order allocation, and general planning solutions that are purpose-built for business users rather than data scientists.

Definition of Modeling A model is a representation of a physical object or process. Modeling Examples As mentioned, modeling can be performed with both physical and mathematical models.

What Is Simulation? Difference Between Optimization Modeling and Simulation It's important to understand that each approach is valid, offering differing insights and information. Using Optimization Modeling and Simulation Together The differences between optimization modeling and simulation can come in handy at times. Explore Our Solutions We offer a suite of supply chain planning, network optimization, order allocation, and general planning solutions that are purpose-built for business users rather than data scientists.
