To perform work assignment including order without useless movement of each worker and allowing reduced operation needed for totaling processing of paper media and for making a work plan in consideration of the detailed content thereof.
From a plurality of work slips 1 each integrated with a wireless tag 12 storing slip information including work details, a work date and a workplace in work information described on a paper medium 11, the pieces of slip information on respective work slips 1 are collectively read with a wireless tag reader 21, and are stored in a work slip storage part 341 of a management terminal 3. On the basis of the identification information on a worker inputted from a manager and stored in a worker information storage part 343, the pieces of slip information, and movement cost calculated from map data and required for every combination of movements between two workplaces stored in a movement cost storage part 344, a traveling route for each worker which provides the minimum total of movement costs and an equal movement amount for each worker is set as an objective function of an traveling salesman problem, and an optimization algorithm such as a genetic algorithm is used to derive the traveling route.
