What advantages and limitations of project management were identified in the simulation

Access Check

Advantages of Simulation One of the primary advantages of simulators is that they are able to provide users with practical feedback when designing real world systems. This allows the designer to determine the correctness and efficiency of a design before the system is actually constructed. Consequently, the user may explore the merits of alternative designs without actually physically building the systems. By investigating the effects of specific design decisions during the design phase rather than the construction phase, the overall cost of building the system diminishes significantly.

  4. After carefully weighing the ramifications of each design, the best circuit may then be fabricated.

As an example, consider the design and fabrication of integrated circuits. During the design phase, the designer is presented with a myriad of decisions regarding such things as the placement of components and the routing of the connecting wires.

Advantages and Disadvantages of Simulation in Operation Research

It would be very costly to actually fabricate all of the potential designs as a means of evaluating their respective performance. Through the use of a simulator, however, the user may investigate the relative superiority of each design without actually fabricating the circuits themselves.

By mimicking the behaviour of the designs, the circuit simulator is able to provide the designer with information pertaining to the correctness and efficiency of alternate designs. After carefully weighing the ramifications of each design, the best circuit may then be fabricated. Another benefit of simulators is that they permit system designers to study a problem at several different levels of abstraction.

By approaching a system at a higher level of abstraction, the designer is better able to understand the behaviours and interactions of all the high level components within the system and is therefore better equipped to counteract the complexity of the overall system. This complexity may simply overwhelm the designer if the problem had been approached from a lower level.

As the designer better understands the operation of the higher level components through the use of the simulator, the lower level components may then be designed and subsequently simulated for verification and performance evaluation. For example, with respect to circuits, it is often useful to think of a microprocessor in terms of its registers, arithmetic logic units, multiplexors and control units.

A simulator which permits the construction, interconnection and subsequent simulation of these higher level entities is much more useful than a simulator which only lets the designer build and connect simple logic gates.

Working at a higher level abstraction also facilitates rapid prototyping in which preliminary systems are designed quickly for the purpose of studying the feasibility and practicality of the high-level design.

ADVANTAGES AND DISADVANTAGES OF SIMULATION Quantitative Techniques for management

Thirdly, simulators can be used as an effective means for teaching or demonstrating concepts to students. This is particularly true of simulators that make intelligent use of computer graphics and animation. Such simulators dynamically show the behaviour and relationship of all the simulated system's components, thereby providing the user with a meaningful understanding of the system's nature. Consider again, for example, a circuit simulator.

By showing the paths taken by signals as inputs are consumed by components and outputs are produced over their respective fanout, the student can actually see what is happening within the circuit and is therefore left with a better understanding for the dynamics of the circuit.

Such a simulator should also permit students to speed up, slow down, stop or even reverse a simulation as a means of aiding understanding. This is particularly true when simulating circuits which contain feedback loops or other operations which are not immediately intuitive upon an initial investigation. During the presentation of the design and implementation of the simulator in this report, it will be shown how the above positive attributes have been or can be incorporated both in the simulator engine and its user interface.
