Question 1

Simulation is used in manufacturing management to determine production schedules,inventory Levels and to do capacity planning.

Accepted Answer

Simulation is a useful tool in manufacturing management and can be used to determine a variety of factors including production schedules, inventory levels, and capacity planning. By using simulation, manufacturers can better predict and prepare for changes in their production process, leading to more efficient and profitable operations.

Question 2

In a simulation model time can be advanced by fixed or variable time increments.

Accepted Answer

Time can be advanced in simulation models by fixed or variable increments depending on the requirements of the model and the specific simulation software being used. Some models may require fixed increments to maintain consistency and accuracy, while others may benefit from variable increments to simulate more complex and dynamic systems.

Question 3

General-Purpose Simulation Software (GPSS)is really a computer language that allows programmers to build their own simulation models.

Accepted Answer

GPSS is indeed a computer language designed to create simulation models.

Question 4

Simulation models are classified as discrete if they are based on mathematical equations.

Accepted Answer

Simulation models are classified as continuous if they are based on mathematical equations. Discrete simulation models are based on events or transactions that occur at distinct points in time.

Question 5

Special-Purpose Simulation Software is specially built to run specific applications that have provisions in manufacturing models to allow for specifying the number of work centers,their descriptions,arrival rates and even batch sizes.

Accepted Answer

Special-Purpose Simulation Software is designed to run specific applications that have pre-built models with provisions for specifying various parameters such as work centers, arrival rates, batch sizes, etc. This makes it easier for users to simulate real-world manufacturing scenarios and study their impact on various performance metrics.

Question 6

Time incrementing is a concept of a simulated clock.

Accepted Answer

Time incrementing is a fundamental aspect of creating simulated clock in software engineering, which involves stepping forward in time by a predetermined interval or "tick."

Question 7

As stated in the textbook,there are five different categories of probability distributions that can be used for a simulation study.

Accepted Answer

There are more than five categories of probability distributions, including discrete, continuous, univariate, multivariate, and others, which can be used in simulation studies.

Question 8

In order to develop the random number intervals for a simulation study we need to know the probability distributions in the situation to be simulated.

Accepted Answer

In order to generate random numbers that accurately simulate a situation, it is important to know the probability distribution of the variables involved, so that appropriate random number intervals or distributions can be developed.

Question 9

When we have performed a simulation run of a model another simulation experiment might be called for that requires a change in parameters or variables.

Accepted Answer

When we perform simulation runs of a model, we might need to change parameters or variables to answer different research questions or scenarios. Therefore, another simulation experiment might be called for with different settings.

Question 10

Decision rules in a simulation are a set of conditions under which the behavior of the simulation model is observed.These rules are either directly or indirectly the focus of most simulation studies.

Accepted Answer

Decision rules are an important aspect of simulation studies as they determine the behavior of the model under specific conditions. Therefore, the statement is true.

Question 11

The run length of a simulation depends on the purpose of the simulation.

Accepted Answer

The run length of a simulation is determined by the purpose and goals of the simulation. Different simulations may require different run lengths to achieve the desired outcomes.

Question 12

In a simulation model time cannot be advanced by variable time increments.

Accepted Answer

In a simulation model, time can be advanced by variable time increments, unlike in discrete event models where time is advanced in discrete increments. This allows for a more continuous and flexible representation of events in the simulated system.

Question 13

Spreadsheet simulations have become obsolete due in part to specialized computer simulation languages like SLAM or SIMAN.

Accepted Answer

This statement is false. Spreadsheet simulations are still commonly used and have not become obsolete, although specialized computer simulation languages have expanded the options for simulation modeling.

Question 14

Simulation models are classified as continuous if the simulation occurs at specific event points,like a piece of machinery in a factory breaking down.

Accepted Answer

Simulation models are classified as continuous if the simulation occurs over a continuous time period, while discrete event simulation models occur at specific event points.

Question 15

Regardless of the computer language chosen for a simulation model,too much data from a simulation can be dysfunctional to problem solving.

Accepted Answer

Too much data can lead to information overload and make it difficult to identify and analyze the most important aspects of the simulation. It is important to carefully select and manage the data collected during a simulation in order to effectively solve the problem at hand.

Question 16

A simulation model does not have to be validated to provide accurate information.

Accepted Answer

Validation is crucial to ensure that the simulation model accurately represents the real system being simulated. Without validation, there is a risk of relying on inaccurate or misleading information from the simulation, leading to poor decision-making.

Question 17

Operations and supply management simulations are most usually the continuous type.

Accepted Answer

Continuous simulations are not the most common type in operations and supply management; discrete-event simulations are more frequently used to model specific events and processes.

Question 18

An empirical probability distribution used in a simulation study is one derived from a standard mathematical distribution like the normal or Poisson probability distributions.

Accepted Answer

An empirical probability distribution is derived from observed data, not from a standard mathematical distribution.

Question 19

Run length and run time are the same thing.

Accepted Answer

The answer of Run length and run time are the...

Question 20

The first step in the major phase "constructing the simulation model" is to determine which properties of the system should be fixed (called parameters)and which should be allowed to assume different values (called variables)throughout the simulation run.

Accepted Answer

This statement is true. One of the first steps in constructing a simulation model is to identify the parameters and variables of the system to be modeled. Parameters are fixed properties of the system that do not change during the simulation run, while variables are properties that can vary over time or in response to different conditions. Defining these parameters and variables is essential to creating an accurate and effective simulation model.
