This assignment requires completing various problem sets related to service blueprints, probability calculations, system reliability, and backup strategies, and then submitting the work either through Excel files or Word documents. The tasks encompass creating service process blueprints for banking services, analyzing failure points in ATM withdrawals, calculating system operation probabilities, determining minimum component performance levels, evaluating robot component reliabilities, and assessing combined probabilities for research project success. The assignment emphasizes understanding process mapping, failure analysis, probability theory, and reliability engineering, applying these concepts through practical problem-solving scenarios documented in Word and Excel formats.

The following comprehensive analysis addresses each problem outlined in the assignment, integrating principles of operations management, reliability engineering, and probability theory to provide detailed solutions and insights.

Question 1: Service Blueprint for Making a Savings Account Deposit

A service blueprint for making a savings account deposit at a bank teller involves delineating the sequential steps taken by the customer and bank personnel, highlighting both front-stage activities and back-stage processes. The process begins when the customer approaches the teller counter, presenting their deposit slip and funds. The teller then verifies the amount, enters the details into the banking system, processes the deposit, and provides a receipt. Back-stage activities include the teller accessing the account database, validating funds, and updating the account balance. Supporting systems like cash counting, accounting software, and security protocols operate behind the scenes. Visualizing these steps in Word enables a clear understanding of the service delivery process, potential bottlenecks, and opportunities for enhancing customer satisfaction.

Question 2: Service Blueprint for Applying for a Home Equity Loan

The process of applying for a home equity loan involves multiple steps, from initial inquiry to final approval. The customer begins with submitting an application form either online or in person, providing documentation such as proof of income, property details, and credit information. The bank's loan officers then evaluate the application, perform credit checks, appraise the property, and assess risk. These activities involve back-end processes, including data verification, credit analysis, and approval workflows. Communication with the customer occurs at various points, offering updates or requesting additional information. Creating this blueprint in Word allows for identifying critical moments and potential delays, facilitating process improvements and better customer service.

Question 3: Steps for Making an ATM Cash Withdrawal and Potential Failure Points

The steps involved in withdrawing cash from an ATM include:

  1. Insert bank card into ATM
  2. Enter PIN on the keypad
  3. Select 'Withdraw Cash' from menu
  4. Enter withdrawal amount
  5. Confirm transaction
  6. ATM processes request and dispenses cash
  7. Card is returned or retained for security reasons
  8. Print receipt if requested

Potential failure points include:

  • Card jam or reader malfunction — the card might get stuck or the reader may malfunction, preventing access.
  • Incorrect PIN entry — multiple wrong attempts could lock the card.
  • Insufficient funds — account balance may be inadequate for the requested withdrawal.
  • Cash dispenser jam — cash may not be dispensed properly.
  • Network or system failure — transaction processing might fail due to connectivity issues.
  • Receipt printer malfunction — receipt may not print, causing confusion.

This analysis, documented in Word, underscores the importance of identifying failure points to improve ATM reliability and customer experience.

Question 4: System Operation Probabilities

Given the system structure with components having reliability 0.90 and switches with specified reliabilities, the probability calculations are as follows:

  1. For the system as shown: If it is a series system, the probability that the system operates is the product of the reliabilities of its components, i.e., \(0.90 \times 0.90 = 0.81\).
  2. With backup components having a 0.90 probability and a switch at 100% reliability, the probability that the backup system operates increases, often modeled using the reliability of a parallel system: \(1 - (1 - 0.90)^2 = 0.99\).
  3. For backups with 0.90 reliability and a 99% reliable switch, the combined system reliability can be computed considering both parallel and series configurations, leading to integrated probability calculations involving complex probability formulas.

Due to the complexity, precise probability values require detailed schematic analysis, but approximations demonstrate that system reliability significantly improves with backups and high-reliability switches.

Question 5: Minimum Reliability of Components for System Performance

The system performance depends on all components functioning, modeled by the product of individual reliabilities. To achieve a system reliability of 0.92 with three identical components, we solve:

\[ r^3 = 0.92 \]

\[ r = \sqrt[3]{0.92} \approx 0.974 \]

Therefore, each component must have a minimum reliability of approximately 0.974 to ensure the overall system meets the 0.92 performance criterion.

Question 6: Reliability of a Robot's Components and Backup Strategies

Individual component reliabilities are A: 0.98, B: 0.95, C: 0.94, D: 0.90. The overall robot reliability, assuming all components are in series, is:

\[ R_{robot} = 0.98 \times 0.95 \times 0.94 \times 0.90 \approx 0.787 \]

Plugging the values in, the overall reliability is approximately 0.787. To improve reliability, a backup component with the same reliability can be added to each component. The backup component's placement depends on which one improves the overall reliability the most. The component with the lowest reliability (D: 0.90) will benefit most from the backup, increasing the probability of success significantly.

Adding a backup with reliability 0.90 results in combined reliability calculations between series and parallel configurations. For the backup of component D, the new reliability would be higher, approximately calculated by:

\[ R_{D} = 1 - (1 - 0.90)^2 = 0.99 \]

This high reliability of the backup boosts overall system reliability to approximately 0.902 when applied optimally.

Similarly, adding a backup with 0.92 reliability to component C yields a comparable increase, with precise calculations guiding the optimal choice for maximum reliability enhancement.

Question 7: Probability that the Research Task Fails to Complete on Time

The probability that all three teams fail to complete the task on time is calculated by considering the complementary probability that at least one team succeeds:

P(all fail) = 1 - [P(team 1 succeeds) + P(team 2 succeeds) + P(team 3 succeeds) - ...]

Since teams work independently, the probability that each fails is 1 minus their success probability:

\[

P_{\text{fail}} = (1 - 0.9) \times (1 - 0.8) \times (1 - 0.7) = 0.1 \times 0.2 \times 0.3 = 0.006

\]

Thus, the probability that the task will not be completed in time (i.e., all teams fail) is approximately 0.006, or 0.6%.

Question 8: Submission of Excel or Picture of Work

This task involves attaching the completed Excel files or images demonstrating the detailed solutions for the above problems.
