Publication number: 20230359949Abstract: A recovery assistance device according to an embodiment includes an analysis unit and a learning unit. The analysis unit generates a first procedure plan related to recovery work of a first failure by solving an optimization problem on the basis of first information related to the first failure. The learning unit acquires feedback information related to work procedure adopted for the recovery work of the first failure and generates a learning result reflecting the feedback information with respect to the first procedure plan. In a case where a second failure occurs, the analysis unit further generates a second procedure plan related to recovery work of the second failure using the learning result.Type: ApplicationFiled: September 25, 2020Publication date: November 9, 2023Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Shohei NISHIKAWA, Shunsuke KANAI, Satoshi SUZUKI, Chao WU, Manami OGAWA, Kazuaki AKASHI, Naomi MURATA

Publication number: 20230274216Abstract: A delivery plan creation device according to an aspect of the invention creates a delivery plan including an order of delivery of fuel to each of destinations using a delivery vehicle and an amount of fuel to be supplied. The delivery plan creation device includes a database, a storage unit, and a processor. The database holds environment information including destination information related to the destination and delivery vehicle information related to the delivery vehicle. The storage unit stores a trained model created by training a neural network having at least an input layer and an output layer in advance based on different environment information. The processor includes an acquisition unit and a creation unit. The acquisition unit accesses the database to acquire the environment information and create an input condition that is a premise of the delivery plan from the environment information.Type: ApplicationFiled: August 21, 2020Publication date: August 31, 2023Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Kazuaki AKASHI, Shunsuke KANAI, Satoshi SUZUKI, Chao WU, Shohei NISHIKAWA, Naomi MURATA, Manami OGAWA
