A work assistance method 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 method causing a computer to execute a process, the process comprising:

• acquiring, 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;
• performing 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
• determining a work priority order of each of the devices based on the estimated processing times, and outputting the work priority order.
