1. A management system, comprising: at least one delivery request indicating a plurality of devices, each comprising a respective quantity; a plurality of equipment to test the devices, each equipment comprising an equipment configuration; and a simulator configured to retrieve device configuration requirements of respective devices, map the devices to the equipment according to the respective device configuration requirements and the equipment configurations to obtain a mapping result, and calculate at least one performance index based on the mapping result and the quantity of respective devices, wherein the performance index comprises a CLIP (Confirm Line Item Performance), and the simulator calculates the CLIP according to: CLIP = MD TD , wherein MD is the number of devices with at least one of the equipment mapped, and TD is the total number of devices, and wherein the performance index comprises a CVP (Confirm Volume Performance), and the simulator calculates the CVP according to: CVP = MQD TQD , wherein MQD is the quantity of devices with at least one of the equipment mapped, and TQD is the total quantity of devices.
