Students arrive at the Administrative Services Office at an average of one every 15 minutes, and their requests take on average 10 minutes to be processed. The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times.
What percentage of time is Judy idle?
How much time, on average, does a student spend waiting in line?
How long is the (waiting) line on average?
What is the probability that an arriving student (just before entering the Administrative
Services Office) will find at least one other student waiting in line?
Burrito King (a new fast-food franchise opening up nationwide) has successfully automated burrito production for its drive-up fast-food establishments. The Burro-Master 9000 requires a constant 45 seconds to produce a batch of burritos. It has been estimated that customers will arrive at the drive-up window according to a Poisson distribution at an average of one every 50 seconds. To help determine the amount of space needed for the line at the drive-up window, Burrito King would like to know
the expected average time in the system
the average line length (in cars), and
the average number of cars in the system (both in line and at the window).
Problem 3
The Bijou Theater shows vintage movies. Customers arrive at the theater line at the rate of 100 per hour. The ticket seller averages 30 seconds per customer, which includes placing validation stamps on customers’ parking lot receipts and punching their frequent watcher cards. (Because of these added services, many customers don’t get in until after the feature has started.) What is the system waiting time if a second window was opened with each server doing all three tasks?
The percentage of time Judy is idle is 1 - (1/15)/(1/10) = 1 - (2/3) = 1/3 = 33.33%. the average time a student spends waiting in line is (1/15)^2 / (2 * (1/10) * ((1/10) - (1/15))) = 1/45 = 0.0222 minutes. the average line length is (1/50) / ((1/45) - (1/50)) = 2.7273 cars. the system waiting time would be (100/60) * (30/60) / (100/60) = 0.5 minutes.
To calculate the answers to the questions for each scenario, we will use the formulas for queueing theory. Here are the calculations for each scenario:
1. For the Administrative Services Office:
- To find the percentage of time Judy is idle, we can use the formula: 1 - (arrival rate/service rate). In this case, the arrival rate is 1 every 15 minutes, and the service rate is 1 every 10 minutes. So, the percentage of time Judy is idle is:
1 - (1/15)/(1/10) = 1 - (2/3) = 1/3 = 33.33%.
- To calculate the average time a student spends waiting in line, we can use the formula: (arrival rate^2)/(2 * service rate * (service rate - arrival rate)). In this case, the arrival rate is 1 every 15 minutes, and the service rate is 1 every 10 minutes. So, the average time a student spends waiting in line is:
(1/15)^2 / (2 * (1/10) * ((1/10) - (1/15))) = 1/45 = 0.0222 minutes.
- To find the average length of the waiting line, we can use the formula: arrival rate^2 / (2 * service rate * (service rate - arrival rate)). In this case, the arrival rate is 1 every 15 minutes, and the service rate is 1 every 10 minutes. So, the average length of the waiting line is :
(1/15)^2 / (2 * (1/10) * ((1/10) - (1/15))) = 1/45 = 0.0222 students.
- To calculate the probability that an arriving student will find at least one other student waiting in line, we can use the formula: arrival rate / service rate. In this case, the arrival rate is 1 every 15 minutes, and the service rate is 1 every 10 minutes. So, the probability is:
(1/15) / (1/10) = 2/3 = 0.6667.
2. For Burrito King:
- To find the expected average time in the system, we can use the formula: 1 / (service rate - arrival rate). In this case, the arrival rate is 1 every 50 seconds, and the service rate is 1 every 45 seconds. So, the expected average time in the system is :
1 / ((1/45) - (1/50)) = 2250 seconds.
- To calculate the average line length, we can use the formula: arrival rate / (service rate - arrival rate). In this case, the arrival rate is 1 every 50 seconds, and the service rate is 1 every 45 seconds. So, the average line length is:
(1/50) / ((1/45) - (1/50)) = 2.7273 cars.
- To find the average number of cars in the system, we can use the formula: arrival rate / (service rate - arrival rate). In this case, the arrival rate is 1 every 50 seconds, and the service rate is 1 every 45 seconds. So, the average number of cars in the system is:
(1/50) / ((1/45) - (1/50)) = 2.7273 cars.
3. For the Bijou Theater:
- To calculate the system waiting time with two servers doing all three tasks, we need to consider the arrival rate and the service rate. The arrival rate is 100 customers per hour, and the service rate is 2 customers per minute (since each server averages 30 seconds per customer). We can use Little's Law to calculate the system waiting time: waiting time = (number of customers in the system) / (arrival rate). The number of customers in the system can be calculated using the formula: arrival rate * (service time + waiting time). In this case, the arrival rate is 100 customers per hour, the service time is 30 seconds, and the waiting time is what we are trying to find. So, the system waiting time would be :(100/60) * (30/60) / (100/60) = 0.5 minutes.

Maintaining the machine is a non value-added activity.
True or false
In lean manufacturing, value-added activities are those that directly contribute to creating value for the customer, while non-value-added activities do not. Maintenance of a machine can be considered a value-added activity if it prevents breakdowns, improves efficiency, or ensures quality.
However, it's important to note that not all maintenance activities are value-added. If maintenance is excessive, poorly executed, or does not directly contribute to customer value, it can become a non-value-added activity. For instance, if a machine is over-maintained, meaning it receives more maintenance than necessary or the maintenance is not properly prioritized.
Therefore, whether maintaining a machine is a value-added or non-value-added activity depends on the specific context, the frequency and type of maintenance performed, and the impact it has on customer value, efficiency, and quality. In summary, maintenance can be a value-added activity if it contributes directly to customer value, efficiency, or quality.

False, Maintaining a machine can be both a value-added and non-value-added activity depending on the context and purpose of maintenance.It is not accurate to categorize all maintenance activities as non-value-added.
In the context of lean manufacturing or process improvement methodologies, non-value-added activities refer to tasks or processes that do not directly contribute to the creation of value for the customer. These activities are considered wasteful and should be minimized or eliminated whenever possible.
While some maintenance activities may fall under the category of non-value-added, such as excessive or unnecessary maintenance that does not directly contribute to the production process, maintenance itself can be a value-added activity in certain situations. Preventive maintenance, for example, aims to proactively maintain equipment to prevent breakdowns and maximize uptime, which directly contributes to operational efficiency and customer satisfaction.
In industries where machine reliability and product quality are crucial, scheduled maintenance, inspections, and repairs can be essential to ensure the smooth operation and optimal performance of equipment. By preventing unplanned downtime, maintaining machine accuracy, and extending equipment lifespan, maintenance activities can enhance productivity, reduce costs, and improve product quality, all of which add value to the overall manufacturing process.

TLS can use RSA and Diffie Hellman protocols for key exchange, while SSH, telnet, and FTPS are unrelated to TLS key exchange.
TLS (Transport Layer Security) is a cryptographic protocol that provides secure communication over a network. It ensures confidentiality and integrity of data exchanged between client and server. Two key exchange protocols used by TLS are RSA and Diffie Hellman.
RSA (Rivest-Shamir-Adleman): RSA is an asymmetric encryption algorithm widely used for secure key exchange. In TLS, RSA allows the server to generate a public-private key pair. The client then encrypts a shared secret using the server's public key, and only the server possessing the corresponding private key can decrypt it.
Diffie Hellman: Diffie Hellman is a key exchange algorithm that allows two parties to establish a shared secret over an insecure channel. TLS can use Diffie Hellman to generate a unique session key, which is used for symmetric encryption. It provides forward secrecy, as even if the long-term private keys are compromised, past communication remains secure.

The Advanced Research Projects Agency Network (ARPANET) was the precursor to the modern internet and was developed by the United States Department of Defense's Advanced Research Projects Agency (ARPA).
The plan for ARPANET was indeed presented in October 1967 by Lawrence Roberts, who was the program manager for the ARPA's Information Processing Techniques Office.
In December 1969, the first ARPANET network became operational. It connected four nodes: the University of California, Los Angeles (UCLA), the Stanford Research Institute (SRI), the University of California, Santa Barbara (UCSB), and the University of Utah.
This initial network was a packet-switched network, meaning that data was divided into packets and transmitted over the network independently before being reassembled at the destination.
However, it's important to note that the correct statement in option a mentions a three-computer network, not a four-computer network. This is because initially, only UCLA, SRI, and UCSB were connected. The University of Utah was added later in 1970, expanding the network to four nodes.
In conclusion, the plan for ARPANET was presented in October 1967, and in December 1969, the first three-computer network, consisting of UCLA, SRI, and UCSB, was up and running.

fluctuations in business activity commonly are referred to as cycles. which of the following industries is best described as counter cyclical?
Fluctuations in business activity that occur over time are often referred to as cycles. These cycles can be classified into three categories: expansion, peak, and contraction.
When we talk about counter cyclical industries, we refer to those that tend to perform well during economic downturns or contractions. These industries can be seen as inversely related to the overall business cycle. One example of a counter cyclical industry is the healthcare sector.
During economic contractions, people may reduce spending on non-essential goods and services. However, healthcare is considered an essential service, meaning that demand for healthcare services remains relatively stable or even increases during economic downturns.

Define decomposition
Answer:
the state or process of rotting
Answer:
I’ve written an essay before about the role of decomposers in a food chain so I’ll just take it from that.
Explanation:
Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to collect inside them.
So, what is this so-called ‘autolysis’? Autolysis, also known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme.
Decomposition is the process by which bacteria and fungi break dead organisms into their simple compounds.

. What are the key components of the architecture Chubb has created?
Why was it important to standardize so much of the architecture?
What are the advantages and disadvantages of a standard EA at Chubb?
Describe how the new architecture supports the goals and strategy of Chubb.
2.The make vs. buy decision is important for every new IT application requested. What, in your opinion, are key reasons an IS organization should make its own systems? What are key reasons to buy an application?
3. When does cloud computing make sense for a large organization that has an IT organization/department? Give an example of cloud computing that might make sense for a start-up company.
The key components of the architecture created by Chubb are as follows:
Standardized technology stack: Chubb standardized the technology stack to ensure consistency and compatibility across different systems and applications.
This included standardizing hardware, operating systems, databases, programming languages, and frameworks.
Service-oriented architecture (SOA): Chubb implemented an SOA approach, where business functions are modularized into services that can be reused and integrated across various applications. This promotes flexibility, scalability, and agility in the IT infrastructure.
Enterprise data model: Chubb developed a standardized enterprise data model that defines the structure and relationships of data across the organization.
Integration middleware: Chubb implemented integration middleware to facilitate seamless communication and data exchange between different systems and applications. This allows for real-time information sharing and improved business processes.
Standardizing much of the architecture was important for Chubb for several reasons:
Efficiency and cost-effectiveness: Standardization reduces complexity, streamlines development and maintenance processes, and allows for economies of scale. It simplifies the management of IT systems and reduces duplication of efforts, leading to cost savings.
Interoperability:
Consistency and quality: By standardizing, Chubb ensures that best practices and proven technologies are used consistently across the organization. This helps maintain a high level of quality and reduces the risk of errors or inconsistencies in the IT landscape.
Advantages of a standard enterprise architecture (EA) at Chubb include improved efficiency, cost savings, increased interoperability, enhanced quality, and the ability to adapt and scale the IT infrastructure effectively. However, there are also disadvantages to consider. Standardization may limit flexibility and innovation, as it may be challenging to introduce new technologies or approaches that deviate from the standardized framework. Additionally, the process of standardization itself can be time-consuming and resource-intensive.
The new architecture at Chubb supports the company's goals and strategy by providing a robust and scalable IT infrastructure. It promotes efficient business processes, enables data-driven decision-making through better integration and analytics, and enhances collaboration and communication across different departments and business units. The standardized architecture also helps Chubb respond quickly to changing market conditions and customer needs by providing a flexible and adaptable technology framework.
Time-to-market: Buying an application can significantly reduce development time and speed up the deployment of new functionality or services. This is especially important when time is critical and market opportunities need to be seized quickly.
Cost savings: Purchasing an off-the-shelf application can often be more cost-effective than building a custom system from scratch, particularly for non-core or non-differentiating functionalities.
Expertise and support: Buying an application provides access to the expertise and support of the vendor, including regular updates, bug fixes, and ongoing maintenance. This can relieve the organization from the burden of continuous development and ensure the system remains up-to-date.
Cloud computing makes sense for a large organization with an IT organization/department in several scenarios:
Scalability: Cloud computing allows organizations to scale their IT infrastructure up or down as needed, making it suitable for handling varying workloads and demands. This scalability is particularly beneficial for large organizations with fluctuating resource needs.
Cost efficiency: Cloud services typically operate on a pay-as-you-go model, allowing organizations to avoid upfront infrastructure investments. This can lead to cost savings, especially for large organizations with significant computing needs.
Flexibility and agility: Cloud services provide a wide range of tools and resources that enable organizations to experiment, innovate, and adapt quickly to changing business requirements. This flexibility is valuable for large organizations with diverse operations and rapidly evolving markets.
An example of cloud computing that might make sense for a start-up company is using a cloud-based Software-as-a-Service (SaaS) solution for customer relationship management (CRM). Start-ups often have limited resources and need to focus on their core business. By using a cloud-based CRM application, they can quickly set up and manage customer data, sales pipelines, and marketing activities without the need to invest in hardware or hire a dedicated IT team. This approach allows them to leverage enterprise-level functionality and security while keeping costs low and focusing on business growth
