Exam 16: Simulation
How are both analysts and managers involved in the validation process?
Analysts and managers play distinct but complementary roles in the validation process, which is a critical component of project management, quality assurance, and decision-making in various business contexts. Here's how both are involved:
Analysts:
1. Data Gathering: Analysts are typically responsible for collecting and preparing the data that will be used in the validation process. They ensure that the data is accurate, relevant, and comprehensive.
2. Technical Expertise: Analysts often have specialized knowledge in statistical methods, data analysis, and modeling techniques. They apply this expertise to design and execute validation tests.
3. Initial Validation: Analysts perform the initial validation checks. They use their skills to analyze the data, run simulations, and test hypotheses to ensure that the models or systems in question are functioning as expected.
4. Reporting Results: After conducting their analyses, analysts compile reports detailing their findings, including any discrepancies or issues identified during the validation process.
5. Recommendations: Based on their findings, analysts may suggest improvements or changes to enhance the system or model's accuracy and reliability.
Managers:
1. Oversight: Managers oversee the validation process to ensure that it aligns with the organization's goals and standards. They provide guidance and set the criteria for what constitutes a successful validation.
2. Resource Allocation: Managers are responsible for ensuring that the validation process has the necessary resources, including personnel, time, and budget.
3. Decision Making: Managers use the information provided by analysts to make informed decisions. They assess the risks and benefits of proceeding with a particular system or model based on the validation results.
4. Stakeholder Communication: Managers often serve as the bridge between the technical team (analysts) and stakeholders. They communicate the outcomes of the validation process to higher management, clients, or regulatory bodies and explain the implications of the findings.
5. Implementation: If changes are recommended, managers are typically responsible for implementing these changes. They coordinate with various departments and ensure that the necessary adjustments are made to improve the system or model.
6. Quality Assurance: Managers are ultimately responsible for the quality and integrity of the validation process. They ensure that the process adheres to industry standards, best practices, and regulatory requirements.
In summary, analysts provide the technical expertise and conduct the detailed work of validation, while managers ensure that the process is aligned with organizational objectives, properly resourced, and that the findings are acted upon appropriately. Both roles are essential for a thorough and effective validation process.
Verification is the process of ensuring that the simulation model provides an accurate representation of the real system.
False
Simulation is an optimization technique.
False
A graphical tool that helps describe the logic of the simulation model is a
A static simulation model is used in situations where the state of the system affects how the system changes or evolves over time.
A discrete-event simulation reviews the status of the system periodically,whether or not an event occurs.
The time required to set up lighting for a portrait studio is uniformly distributed between 12 and 20 minutes.Use the following random numbers to generate the setup time for 10 customers.


The parameters of a simulation model are the controllable inputs.
Simulation models that must take into account how the system changes or evolves over time are referred to as dynamic simulation models.
Three airlines compete on the route between New York and Los Angeles.Stanton Marketing has performed an analysis of first class business travelers to determine their airline choice.Stanton has modeled this choice as a Markov process and has determined the following transition probabilities.
a. Show the random number assignments that can be used to simul ate the first class business traveler's nex airline is , and .
b. Assume the traveler used airline C last. Simul ate which airline the traveler will be using over her next 2 her flights are on each of the three airlines? Use the following random numbers, going from lett to right, to
71 95 83 44 34 49 88 56 05 39 75 12 03 59 29 77 76 57 15 53 37 46 85 24 53

Computer-generated random numbers are normally distributed over the interval from 0 to 1.
If customer 2 has a service time of 1.6,and if customer 3 has an interarrival time of 1.1 and a service time of 2.3,when will customer 3's service be completed?
For any waiting line system, (Average number of units in waiting line)= (Total waiting time)divided by (Total time of simulation).
The process of determining that the computer procedure that performs the simulation calculations is logically correct is called
