Work instruction device, work instruction system, and work instruction method

A work instruction system comprising a work instruction device, a production device, a performance input terminal, and a sensor configured to acquire worker dynamics, wherein

• the production device transmits, to the work instruction device, a history of an operation state of the own device for each time point,
• the performance input terminal transmits, to the work instruction device, production performance information for specifying performances of start and end time points of a manufacturing process for each manufactured object,
• the sensor transmits the acquired worker dynamics information to the work instruction device, and
• the work instruction device comprises:
• a communication unit configured to communicate with each of the production device, the performance input terminal, and the sensor;
• a facility operation history acquisition unit configured to collect the history of an operation state via the communication unit;
• a production performance collection unit configured to collect the production performance information via the communication unit;
• a worker dynamics acquisition unit configured to collect the worker dynamics information via the communication unit;
• a production loss occurrence pattern extraction unit configured to analyze the history of an operation state, the production performance information, and the worker dynamics information based on a predetermined method to generate a production loss occurrence pattern;
• and
• a work instruction generation unit configured to estimate occurrence of a production loss based on a work plan for a work corresponding to a date and time, a facility, and a worker corresponding to the production loss occurrence pattern to generate work instruction information including information on a cause of the production loss.

A work instruction method using a work instruction device, wherein

• the work instruction device comprises:
• a processor;
• and a storage unit configured to store shop-floor data including production performance information for each manufactured object manufactured at a manufacturing shop-floor, worker dynamics information obtained from a sensor attached to a worker at the manufacturing shop-floor, and information on an operation history of a facility at the manufacturing shop-floor, and
• the processor performs:
• a production loss occurrence pattern extraction step of analyzing the shop-floor data based on a predetermined method to generate a production loss occurrence pattern;
• and
• a work instruction generation step of estimating occurrence of a production loss based on a work plan for a work corresponding to a date and time, a facility, and a worker corresponding to the production loss occurrence pattern to generate work instruction information including information on a cause of the production loss.
