[0022] As shown in Figure 1, food manufacturers and other similar businesses have traditionally often performed reprocessing during the manufacturing process (for example, measuring the moisture content of work-in-progress products and, if it does not meet the standards, reheating the product before proceeding to the next process).Until now, it has been necessary to manage reprocessing results separately from regular processing, and the processing costs incurred during reprocessing have been treated as "waste costs," which could not be managed using system-based processing results data or cost data, and detailed analysis has been performed manually, which has meant that analyzing the allowable range for reprocessing takes time and has not been possible to perform accurately.

[0023] Therefore, in this embodiment, a mechanism is provided for comparing the processing results and actual costs that involve reprocessing with the standard manufacturing process and standard costs.

[0024] For example, as shown in FIG. 2, in this embodiment, standard work results in the manufacturing process and working hours for the manufacturing process by item are set, standard costs incurred as direct expenses are held by cost item, working hours for the manufacturing process by item are set, and as work results in the manufacturing process, the work classification, working hours, and equipment operating hours for the work that has occurred are held by manufacturing item, and the cost amounts incurred as direct expenses are held by cost item, thereby listing items that deviate from the acceptable range (exceeding the upper limit) in terms of reprocessing results.

In FIG. 9 (1), the upper row displays the ratio calculated by "number of reworks ÷ number of manufactured items," while the lower row displays the value obtained from the standard manufacturing work master. If "rework > rework ratio," the result is highlighted (in red). Furthermore, in FIG. 9 (2), the result is calculated based on the actual number of reworks, using the standard manufacturing work master, as the estimated work time calculated by "number of reworks ÷ (standard manufacturing work master). number of manufactured items per unit × (standard manufacturing work master). direct rework work time." If "actual rework work time - normal work time < 0," the result is highlighted (in red).
