Simulation, an imitation of system operations or real-world processes over time, is an act that requires building and development of a model that represents key characteristics, behaviors or functions of a selected abstract or physical system or process. The model mainly represents the system itself and simulation, on the other hand, represents the operation of the system over time. It always has been used in many contexts such as technology for performance optimization, training, education, testing, video games and safety engineering. Frequently, computerized experiments are used in studying the simulated models and their adaptivity. Its application to the real world has facilitated its improvement to conform more realistically to the world case scenarios. How does simulation influence the job and the business market?
In business and management, simulations are mathematical imitations of real-world systems. Although, most of them can be sufficiently complex hence requiring the
involvement of computers in their operations. If results of the mathematical model are valid, then the results of the simulation runs will imitate those of the actual system if it was given time to operate amply. Simulations are first developed through modeling after careful study of a certain system by analysts. Although for business simulation purposes, they begin with a statistically-based model which relies on empirical evidence. In some businesses, interviews are conducted through simulators placed on an unseen end to assess a user’s rational thinking and provide eligibility according to suitability.
What I find particularly interesting in a simulation is its ability in assessing and evaluating an applicant’s job potential. They are designed in a way that they are able to conduct cognitive tests, personality tests, and eligibility. Decisions from organizations can be made through work samples and simulations that help immensely in the decision making processes. Job simulations also come with pretty impressive advantages that make applicants fully involved. They provide and extend to applicants’ attention a realistic job preview. Applicants fully qualified for the job are a considerate click, and those who aren’t qualified find it challenging and opt out, hence saving a lot of valuable time and money.
Considering recent technological improvements, assessment and simulation tests through web-based simulations can now be accessed online, this ensures that each 
applicant goes through the same evaluation process and all applicants view the same tests and similar requirements. It also provides an eminent degree of candidate engagement. This is ascertained by the interactiveness and user-friendliness that web-based simulations come accompanied with.
