A work assistance device that assists works for resolving a plurality of problems for simultaneously occurring in a system having a plurality of devices for producing products, the work assistance device including a processor configured to acquire, at occurrence of the plurality of problems, actual historical information on a processing time desired to previously produce the product in each of the devices; perform maximum a posteriori probability estimation of a processing time desired to produce the product in each of the devices, based on prior distribution stored in a storage unit and the acquired actual historical information on the processing time; and determine a work priority order of each of the devices based on the estimated processing times, and output the work priority order.

A system for monitoring maintenance for manufacturing apparatuses in a facility is provided. The system includes at least one manufacturing apparatus, the manufacturing apparatus including an RF identification tag and a module, and a control system. The control system is configured to receive, from the module, operational status information that indicates time periods during which the manufacturing apparatus is in operation, determine a cumulative time duration of operation for the manufacturing apparatus, retrieve a predetermined maintenance interval for the manufacturing apparatus, determine whether the cumulative time duration of operation exceeds the predetermined maintenance interval, and in response to a determination that the cumulative time duration of operation exceeds the predetermined maintenance interval, i) output a signal that causes the manufacturing apparatus to discontinue operation, and ii) cause instructions for completing a required maintenance procedure to be displayed on a display device in communication with the control system.

A method for maintaining, commissioning and checking systems in warehouses, where a service technician has sight of the system in question and, by way of a mobile computer, makes wireless contact with the controller of the system in order to take control thereof, where taking control by the mobile computer is permitted by a central controller only if the service technician can have sight contact with the corresponding system, for which purpose localization services of a local radio network are used for the determination of the position and/or of the orientation of the mobile computer of the service technician.

In a method for error detection and monitoring an electronically closed-loop or open-loop controlled machine part, operating parameters and monitoring parameters of machine parts are recorded and stored. A comparison group of comparable machine parts and comparable operating parameters is determined based on the recorded and stored operating parameters and a machine part to be compared. A statistical analysis procedure is used for creating a threshold value based on the determined comparison group, and for detecting a variance of at least one state or at least one of the monitoring parameters based on the threshold value. The variance is assigned to the machine part.

A method of directing a vehicle body through a paint process includes obtaining, by a vehicle manufacturing system, process operation data from a vehicle body process. The process operation data is indicative of an operation state of an identified machine performing a selected body operation as part of the vehicle body process. The method includes determining, by the vehicle manufacturing system, whether a recognized fault has occurred based on the process operation data, identifying a potential vehicle body imperfection based on a paint process model and the recognized fault, and providing, by the vehicle manufacturing system, a notification to the paint process of the potential vehicle body imperfection for the vehicle body, where the notification includes location information of the potential vehicle body imperfection, a remedial action for addressing the potential vehicle body imperfection, a recommended resource allocation, or a combination thereof.

An alert notification device of a dental processing machine includes a receiver, a first extractor, and a notifier. The receiver receives error information from the dental processing machine. The first extractor extracts from the error information received by the receiver, as first extracted error information, error information that occurred in a predetermined first time. The notifier notifies a management device to be used by a maintenance company to perform maintenance of the dental processing machine, of an alert concerning the first extracted error information.
