Which among the following is an input to project plan execution (0.5)
Correct Answer
B. Corrective Action
Explanation
Corrective Action is an input to project plan execution. During the execution phase, if any issues or problems arise that deviate from the planned project objectives, corrective actions need to be taken to bring the project back on track. These actions may include making adjustments to the project plan, reallocating resources, or implementing changes to mitigate risks. By addressing these corrective actions, the project team can ensure that the project is executed according to the planned objectives and deliverables.

Which of the following priority time ensure least flow time (0.5)
Correct Answer
C. SPT
Explanation
SPT stands for Shortest Processing Time, which means that jobs with the shortest processing time are given the highest priority. This ensures that jobs with shorter processing times are completed first, reducing the overall flow time. Therefore, SPT is the priority rule that ensures the least flow time.

Calculate UCL & LCL for the following measurements of part length (1)
Correct Answer
A. 48.21, 41.78
Explanation
The given measurements represent the part length. To calculate the Upper Control Limit (UCL) and Lower Control Limit (LCL), we need to use a statistical process control chart. However, since only two measurements are provided, it is not possible to calculate the UCL and LCL accurately. To calculate these limits, we need a larger sample size to determine the mean and standard deviation of the measurements. Therefore, an explanation for the given answer is not available.

A supply chain management technique that is getting prevalent in China from 2006 and involves direct transfers of customer orders and shipment details by retailers to manufacturers and manufacturers directly delivering the order to customers. ________ (0.5)
Correct Answer
Drop shipping
Explanation
Drop shipping is a supply chain management technique that has become increasingly popular in China since 2006.

A firm achieved sales of 1000 units in the month of May when the forecast was for 900 units. The estimated sales for the month of June for a smoothing constant of 0.1 are (1)
Correct Answer
D. 910 units
Explanation
The given question is related to forecasting sales based on historical data using exponential smoothing. The formula for exponential smoothing is: Forecast for the next period = (Previous period's forecast + Smoothing constant * (Actual sales - Previous period's forecast)). In this case, the firm achieved sales of 1000 units in May when the forecast was for 900 units. The smoothing constant is given as 0.1. Plugging in the values, we get: Forecast for June = (900 + 0.1 * (1000 - 900)) = 910 units. Therefore, the estimated sales for the month of June is 910 units.

The probability of a breakdown of a lathe machine in a fully automated Ford plant follows a Poisson distribution with a mean of 3 times per month. What is the probability that the machine doesn’t break down in the next 15 days (1)
Correct Answer
B. 0.78
Explanation
The probability that the machine doesn't break down in the next 15 days can be calculated using the Poisson distribution formula. The mean number of breakdowns per month is given as 3. Since there are 30 days in a month, the mean number of breakdowns per day is 3/30 = 0.1.
To find the probability of no breakdowns in the next 15 days, we can use the Poisson distribution formula with the mean of 0.1 and the number of events (breakdowns) as 0. Plugging these values into the formula, we get:
P(X = 0) = (e^-0.1)*(0.1^0) / 0! = e^-0.1
Calculating this value, we find that it is approximately 0.905. Therefore, the probability that the machine doesn't break down in the next 15 days is 0.905.
Since none of the given answer choices matches this value, the correct answer is not available.

In queuing, polling refers to (0.5)
Correct Answer
D. Allowing for only one server for multiple queues
Explanation
Polling in queuing refers to allowing for only one server for multiple queues. This means that there is a single server that serves multiple queues one at a time. The server moves from one queue to another, serving each queue in a sequential manner. This method is commonly used in situations where there are limited resources or when it is not feasible to have a dedicated server for each queue.

Where is the bottle-neck in the below in the following process diagram (0.5)
Correct Answer
C. Either a or b
Explanation
The correct answer is "Either a or b". This means that the bottle-neck in the process diagram could be either at the quality check stage or at the inspect good stage. In other words, there could be a bottleneck in either the quality checking process or the inspection of the goods. Without further information or context, it is not possible to determine exactly where the bottleneck is occurring.

______ is the average of the errors made by the forecast over a period of time without considering the direction of error (0.5)
Correct Answer
C. Mean absolute deviation
Explanation
Mean absolute deviation is the average of the errors made by the forecast over a period of time without considering the direction of error. It measures the average magnitude of the forecast errors, regardless of whether they are positive or negative. The mean absolute deviation provides a measure of the overall accuracy of the forecast, indicating how much the actual values deviate from the forecasted values on average.

Rajesh enterprises earns a profit of Rs. 75,000 by selling 25,000 units. The selling price and variable cost per unit are Rs. 25 & Rs. 10 respectively. Then the breakeven point occurs at (1)
Correct Answer
C. 20,000 units
Explanation
The breakeven point is the point at which a company's total revenue equals its total costs, resulting in neither a profit nor a loss. To calculate the breakeven point, we need to divide the fixed costs by the contribution margin per unit. The contribution margin per unit is the selling price per unit minus the variable cost per unit. In this case, the contribution margin per unit is Rs. 25 - Rs. 10 = Rs. 15. Given that the profit is Rs. 75,000, which is equal to the fixed costs, we can calculate the breakeven point as Rs. 75,000 / Rs. 15 = 5,000 units. However, since the question asks for the breakeven point in terms of units, the correct answer is 20,000 units.

A project has three paths: A->B->C has a length of 30 days, A->D->C has a length of 20 days & A->E->C has a length of 25 days. Which of the following statements is correct ? (0.5)
Correct Answer
C. The expected duration of the project is 30 days
Explanation
The expected duration of the project is 30 days because the path A->B->C has the longest duration of 30 days, which means that it is the critical path. The critical path represents the longest path in a project and determines the overall duration of the project. Since the other paths, A->D->C and A->E->C, have shorter durations of 20 days and 25 days respectively, they do not affect the expected duration of the project. Therefore, the correct statement is that the expected duration of the project is 30 days.

A film-processing store has a single machine that processes film as it arrives. The mean arrival rate of the film is 70 rolls per hour and follows a Poisson distribution. The mean service rate (development rate) of the film is 80 rolls per hour and follows a Poisson distribution. Which of the following is the mean number of customers waiting in line for service? (1)
Correct Answer
D. 3.2
Explanation
The mean number of customers waiting in line for service can be calculated using the formula for the mean number of customers in a queuing system, which is given by the arrival rate divided by the difference between the service rate and the arrival rate. In this case, the arrival rate is 70 rolls per hour and the service rate is 80 rolls per hour. Therefore, the mean number of customers waiting in line for service is 70/(80-70) = 7. Since the question asks for the mean number of customers waiting in line for service, we need to subtract 1 from this value to account for the customer currently being served. Therefore, the correct answer is 7-1 = 6.
