The plant utilization can be calculated by dividing the total time spent on production by the total available time. In this case, the total time spent on production is calculated by multiplying the number of units produced per day by the achievable cycle time, which is 44 units * 10 minutes/unit = 440 minutes. The total available time is calculated by multiplying the number of full-time workers by the working hours after accounting for breaks, which is 100 workers * 8 hours = 800 hours. Converting the total available time to minutes gives us 800 hours * 60 minutes/hour = 48,000 minutes. Dividing the total time spent on production by the total available time and multiplying by 100 gives us (440 minutes / 48,000 minutes) * 100 = 0.9167 * 100 = 91.67%. Therefore, the correct answer is 91.67%.

Delphi forecasting is a forecasting method that involves collecting the opinions and judgments of a group of experts. This method is considered more reliable than individual statements because it combines the collective wisdom and knowledge of multiple experts. By incorporating diverse perspectives and expert opinions, Delphi forecasting aims to reduce biases and errors that may be present in individual forecasts. This collaborative approach helps to ensure more objective and accurate outcomes in the forecasting process.

In order to determine the theoretical number of machines required, we need to consider the total available working hours in a day and the time it takes to complete each unit.

Each shift operates for 8 hours, and there are 3 shifts in a day, so the total available working hours are 3 x 8 = 24 hours.

The setup time for each machine is 1 hour in each shift, so the total setup time in a day is 3 x 1 = 3 hours.

Therefore, the total productive working hours in a day is 24 - 3 = 21 hours.

The daily demand is 3780 units, and the sum of task times is 100 seconds.

To calculate the number of machines required, we divide the total productive working hours by the time it takes to complete each unit:

Number of machines = (Total productive working hours x 3600 seconds) / (Daily demand x sum of task times)

Number of machines = (21 x 3600) / (3780 x 100)

Number of machines = 5

Hence, the correct answer is 5.

The two sources of costs in queuing analysis are waiting customers and capacity. Waiting customers refer to the cost incurred due to customers waiting in line, such as the loss of productivity or customer dissatisfaction. Capacity refers to the cost associated with the resources required to handle customers, such as staffing, equipment, or space. By managing these two factors effectively, businesses can optimize their queuing systems and minimize costs.

This layout arranges workstations in a U-shaped formation, allowing for efficient flow of materials and minimizing movement and transportation time. It promotes better communication and coordination among workers and provides a clear view of the entire production process. This layout is particularly suitable for small batch production and helps in reducing waste and improving productivity.

In a simple exponential smoothing problem, the smoothing constant (α) determines the weight given to the previous forecast. The fact that the previous forecast was six units less than the actual demand suggests that the model was not able to fully capture the demand pattern. To adjust for this, a smaller α value is needed to give more weight to the actual demand and less weight to the previous forecast. Since the next forecast is 66.9, which is closer to the actual demand, it indicates that the model is improving. Among the given options, 0.15 is the most reasonable choice for α as it strikes a balance between giving weight to the previous forecast and adjusting for the forecasting error.

Strategic planning decisions involve the development of organizational objectives and the setting of frameworks to achieve those objectives.

Strategic planning decisions help guide the overall direction of the organization and align its resources and activities towards achieving its long-term goals.

Mr. A collects data in subgroups of size 7, which is typically used for measuring process stability. The Xbar-R chart is used to monitor the process mean and variability over time. The Xbar chart is used to monitor the process mean, while the R chart is used to monitor the process variability. Therefore, Mr. A would use the Xbar-R chart to measure the subgroup variability in the manufacturing industry.

A P-Chart is used in this case because it is used to monitor the proportion of defective items or occurrences in a process. In this scenario, the team is monitoring the number of applications with incomplete fields, which can be considered as defective applications. The P-Chart will help track the proportion of incomplete applications received each day and determine if the process is in control or if there are any significant variations.

Management by objectives is not associated with the concept of 'lean production' because lean production focuses on eliminating waste and improving efficiency in the production process, while management by objectives is a goal-setting and performance management technique that focuses on aligning individual goals with organizational objectives. Although management by objectives can be used in conjunction with lean production principles, it is not inherently a part of lean production itself.

The Kano model is a tool used in the define phase of a Six Sigma project to prioritize Critical-to-Quality (CTQ) factors. The Kano model categorizes CTQ factors into three categories: basic, performance, and excitement. Basic factors are expected by customers and their absence leads to dissatisfaction, while performance factors are desired by customers and their presence leads to satisfaction. Excitement factors are unexpected by customers and their presence leads to delight. By understanding the different categories of CTQ factors, the Kano model helps in prioritizing them based on their impact on customer satisfaction and business goals.

Based on the information provided, the project has three paths: A—B—C, A—D—C, and A—E—C. The length of path A—B—C is 25 days, which means that this is the expected duration of the project. Therefore, the correct statement is "The expected duration of the project is 25 days."

The breakeven point occurs when the total revenue equals the total cost, resulting in zero profit. In this case, the total revenue can be calculated by multiplying the selling price per unit (Rs. 25) by the number of units sold. The total cost can be calculated by multiplying the variable cost per unit (Rs. 10) by the number of units sold, and adding the fixed costs. Since the profit is Rs. 75,000, the fixed costs can be calculated by subtracting the total cost from the total revenue. By rearranging the equation, we can solve for the breakeven point, which is 20,000 units.

The correct answer is "Available to promise." Available to promise is a term used in supply chain management to refer to the uncommitted inventory balance in the first period of a Master production schedule. It is calculated for each period in which a MPS receipt is scheduled. This term indicates the quantity of inventory that is available to be promised to customers or to fulfill future orders.

It provides a hierarchical representation of the project team, including the project manager, functional managers, and team members. This structure helps to clarify roles and responsibilities within the project and ensures effective communication and coordination among team members. It also helps to identify the reporting lines and authority levels within the project organization.

Nash equilibrium refers to a situation where no supply chain partner can improve their utility by unilaterally changing their strategy, given the strategies chosen by the other partners. In this hypothetical scenario, all supply chain partners have reached a point where they have maximized their utility and any change in strategy would not result in any further improvement. Therefore, the correct answer is Nash equilibrium.

Fixed-sequence robots are most useful in product-focused production systems. In a product-focused system, the production process is organized around specific products or product lines. This means that the production is repetitive and standardized, with a fixed sequence of operations required to produce the product. Fixed-sequence robots are designed to perform a specific set of tasks in a predetermined order, making them well-suited for product-focused systems where the production process follows a fixed sequence.

The given advantages and disadvantages indicate that the model being discussed is the mixed model assembly. This model allows for reduced inventory and improved service levels by producing multiple product variants in smaller batches.

In this case, Mr. Ram is using the C & E matrix to collect subjective data and make quantitative estimates of the key process input variables on key process output variables. This will help him understand the most important factor that needs improvement in order to enhance the overall process efficiency and reduce defects.

Mean Absolute Deviation is the average of the errors made by the forecast over a period of time without considering the direction of error. This means that it calculates the average magnitude of the errors, regardless of whether they are positive or negative. It is a measure of the overall accuracy of the forecast, indicating how far off the forecasted values are from the actual values on average.

The efficiency of balance in an assembly line is calculated by dividing the sum of task time by the cycle time and multiplying by 100. In this case, the sum of task time is 30 seconds and the cycle time is 20 seconds. Therefore, the efficiency of balance is (30/20) * 100 = 1500/20 = 75%.

Fourth party logistics refers to a strategic relationship between an organization and its clients where the organization provides management and oversight services for the client's logistics and transportation providers. Unlike third-party logistics, which involves outsourcing logistics operations to a third-party provider, fourth party logistics focuses on managing and coordinating multiple logistics providers on behalf of the client. This arrangement allows the organization to have greater control and visibility over the entire supply chain process.

The first order exponential smoothing technique uses a weighted average of past demand values to forecast future demand. The forecast for each month is calculated using the formula: Forecast = (1-alpha) * Actual + alpha * Forecast (where alpha is the smoothing constant). In this case, the actual demand for the last four months and the forecasted demand for the previous month are given. By plugging in the values and solving the equation, we find that the forecasted demand for the month of Sep-2015 is 50.7.

The statement "A certain percentage of rejects from a supplier is acceptable" is not associated with JIT Purchasing because JIT Purchasing focuses on reducing waste and improving efficiency in the supply chain. Accepting a certain percentage of rejects would lead to inefficiencies and potential disruptions in the production process.
