An information processing device includes a controller that: inputs information that is based on a raw material of a product that is produced at a plant to a physical model and acquires a first output result; inputs component information that is based on optical spectrum data that are obtained by spectroscopic sensing for the raw material and an output of the physical model to a machine learning model and acquires a second output result; and outputs information concerning a state of the plant based on the first output result and the second output result.

To improve utilization of materials and reduce wastage, there is provided a method for managing remnant materials from a manufacturing process. A digital remnant image of a remnant is obtained and processed to calculate size and shape data for the remnant. A CAD file of the remnant comprising the size and shape data can be created and stored. Remnant CAD files may be searchable so that subsequent design and manufacturing process may make use of the remnants. The remnants may be tagged with an ID, e.g. barcode, that allows the storage location of the remnant to be tracked for retrieval of the remnant when required.

An injection molding management system includes: a molding information storage unit configured to store molding information on the usage of each type of molding material used in forming product molding, for each kind of molding; a remaining product quantity calculator configured to calculate the remaining product quantity of each kind of molding; a total usage calculator configured to calculate the total usage of each type of molding material used in the injection molding machines, based on the molding information of each kind of molding and the remaining product quantity of molding; a stock quantity storage unit configured to store the stock quantity of molding material; and an order quantity calculator configured to calculate the order quantity of each type of molding material, based on the total usage and the stock quantity of the molding material.

A device and a method for analyzing a manufacturing apparatus are provided. The device includes a storing unit, a detecting unit, a calculating unit and a determining unit. The storing unit is for storing a supply amount of material. The detecting unit is for continuously detecting the manufacturing apparatus once the material is used during whole of a process to obtain a total usage. The calculating unit is for calculating a usage ratio of the total usage to the supply amount. The determining unit is for determining whether the manufacturing apparatus is operated in a usage trouble operation according to the usage ratio.
