Safety factor is a multiplier that is applied to the standard deviation of demand to determine the safety stock level. Safety factor remains constant while maintaining the same customer service level, as it reflects the desired probability of not stocking out. The higher the safety factor, the higher the customer service level, and vice versa. The other factors do not remain constant while maintaining the same customer service level. Reorder point (ROP) is the inventory level that triggers a replenishment order. ROP increases with increasing forecast error, as more safety stock is needed to cover the demand uncertainty. Safety stock is the inventory that is carried to protect against forecast errors and demand fluctuations. Safety stock increases with increasing forecast error, as more buffer is needed to avoid stockouts. Inventory investment is the total value of the inventory that is held in the system. Inventory investment increases with increasing forecast error, as more inventory is required to maintain the same customer service level. References: Safety Factor | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

The discrete available-to-promise (ATP) method is a calculation based on the available-to-promise figure in the master schedule. For the first period, the ATP is the sum of the beginning inventory plus the MPS quantity minus backlog for all periods until the item is master scheduled again. For other periods, the quantity that is available for an item is based on the quantity available within an individual purchase. Therefore, the master production receipt quantity is committed to requests only for shipment before the next MPS receipt12. References:

The sales and operations plan (S&OP) is the most appropriate level to adjust when a major new customer is received from sales. The S&OP is a cross-functional process that aligns the demand and supply plans with the business strategy and financial goals. It also provides the basis for the masterproduction schedule (MPS), which is a more detailed and disaggregated plan for specific products or families. Adjusting the production volume or the forecast would not be sufficient to account for the impact of the new customer on the overall business objectives and resources. References:

The service part demand can be included in the gross requirements for the part. Gross requirements are the total demand for an item derived from all sources, such as customer orders, dependent demand, forecast, or safety stock. Service part demand is the demand for an item that is used to replace or repair a product after it has been sold to the customer. Service part demand is independent of the production of other items, and it can be forecasted based on historical data, warranty information, or customer contracts. Service part demand can be added to the gross requirements for the part, along with the dependent demand from the other part that uses it as a component.

Option A is not correct, because the low-level code of the part is not zero. Low-level code is the lowest level in the bill of material (BOM) at which an item appears as a component. An item that is not a component of any other item has a low-level code of zero. An item that is a component of another item has a low-level code equal to one plus the low-level code of the parent item. In this case, the part is a component of another part, so its low-level code is at least one.

Option B is not correct, because the material requirements for the part will not be understated. Material requirements are the net requirements for an item after deducting the available inventory and scheduled receipts from the gross requirements. If the service part demand is included in the gross requirements, the material requirements will reflect the true demand for the part. If the service part demand is not included, the material requirements will be understated, and the part may face stockouts or backorders.

Option D is not correct, because the part should have some safety stock. Safety stock is the extra inventory held to protect against uncertainties in demand, supply, or lead time. Safety stock can help reduce the risk of stockouts, improve customer service, and buffer against variability. The part should have some safety stock to account for the fluctuations in the service part demand, which may depend on factors such as product failure rate, customer behavior, or environmental conditions.
