Time series decomposition is a method that breaks down a time series of historical demand data into its components: trend, seasonality, cyclical, and random. It is appropriate for forecasting the demand for a product family when there is a significant trend and seasonality in the demand history, as it can isolate and estimate these components and project them into the future. Time series decomposition can also handle cyclical and random variations in demand, and it can be applied to different time intervals (such as monthly, quarterly, or yearly). The other methods are not suitable for this scenario. Econometric models are complex mathematical models that use regression analysis to relate demand to various explanatory variables, such as price, income, or advertising. They are not designed to capture trend and seasonality in demand. Computer simulation is a technique that uses a computer program to mimic the behavior of a real system under different scenarios and assumptions. It is not a forecasting method per se, but rather a tool for testing and evaluating different forecasting methods or policies. Weighted moving average is a simple method that uses the average of the most recent observations as the forecast for the next period, with more weight given to the recent observations than the older ones. It is not able to capture trend and seasonality in demand, as it assumes that demand is stable and does not change over time. References: Time Series Decomposition | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

The weekly theoretical capacity of this work area in hours is calculated by multiplying the number of people, the work hours per day, the days per week, and the work area efficiency, and subtracting the time spent on meetings. The formula is:

Capacity=(3×10×4×0.85)−(3×0.5×4)

Capacity=(102)−(6)

Capacity=96

The closest answer to this value is 120, which is option D.References:=

The primary outcome of frequent replenishments in a distribution requirements planning (DRP) system is that the level of required safety stock is reduced. Safety stock is the extra inventory that is held to protect against demand uncertainty or supply variability. Frequent replenishments mean that the inventory is replenished more often and in smaller quantities, which reduces the risk of stockouts and the need for safety stock. Frequent replenishments also improve the inventory visibility and accuracy, which enable better demand forecasting and inventory planning. By reducing the safety stock, the company can lower its inventory carrying costs, free up working capital, and increase its inventory turnover. The other options are not correct, as they are not the primary outcome of frequent replenishments, but rather possible benefits or drawbacks of frequent replenishments, depending on the situation:

• Lead times to customers decrease: This may or may not be true, depending on the distance between the distribution centers and the customers, the transportation mode and frequency, and the customer service level. Frequent replenishments may reduce the lead times if the distribution centers are closer to the customers and the transportation is fast and reliable. However, frequent replenishments may also increase the lead times if the distribution centers are far from the customers and the transportation is slow and infrequent.
• Transportation costs decrease: This may or may not be true, depending on the transportation mode, distance, and volume. Frequent replenishments may reduce the transportation costs if the transportation mode is economical, the distance is short, and the volume is high. However, frequent replenishments may also increase the transportation costs if the transportation mode is expensive, the distance is long, and the volume is low.
• More efficient load consolidation occurs: This is unlikely to be true, as frequent replenishments usually mean smaller shipments that are less likely to fill the capacity of the transportation vehicles. Load consolidation is the process of combining multiple shipments into one larger shipment to optimize the transportation efficiency and reduce the transportation costs. Frequent replenishments may reduce the opportunities for load consolidation and increase the transportation inefficiency and costs. References:

A company that uses two-level master scheduling has a master production schedule (MPS) for the end items (kits) and a final assembly schedule (FAS) for the components (tools). The forecasts that are input to master scheduling should reflect the total number of kits and the specific kit configurations, as these determine the demand for the components. The other options are not relevant for master scheduling, as they do not reflect the end item demand or the bill of materials structure. References: EXAM CONTENT MANUAL PREVIEW, page 10, section 4.1.2. Manufacturing Planning and Control for Supply Chain Management: The CPIM Reference, Second Edition, page 163, section 6.2.
