Final answer:
The planned-order release in an MRP report assists in ordering materials for production. The number of defective products compared to total production needs separate quality data, not provided in the cost data example.
Step-by-step explanation:
Planned-order releases are a crucial aspect of a Material Requirements Planning (MRP) system. These releases indicate the number of items that need to be ordered or produced in each period to meet the master production schedule demands. Typically, a factory manager uses the MRP report to understand not just the quantities but also the financial aspect of production, such as the amount spent on parts each period, as shown in the example given.
To determine the defect ratio, the manager needs to compare the number of defective products to the total number produced. While information on the amount spent provides some insight into operations, determining the number of defects requires an analysis of production quality data, which might be listed in a separate table (like Table 11.5 in the question), and not shown in the provided snippet. The data provided in the example shows different periods (Pd) with corresponding prices and the amount spent on items. To assist a factory manager in understanding defects versus production quantity, we would need additional information about units produced and the defect count for each period.
