Digital Transformation of Logistic and Maintenance for Water/City-Gas Supply Infrastructures

This paper deals with application of cutting-edge information technology represented by Digital Transformation, DX, for maintaining critical infrastructures such as water and city-gas supply systems. Among many stakeholders related to such infrastructure, we have focused on system maintenance for the end-user by focusing on manufacturing, wholesale and retail, logistic, and on-site construction that formulate a very complex System of System. First, this paper describes a successful example of DX application to the water supply system. Second, the approach and means of this example were applied to an obsolete system of a city-gas supply system with successful results in relatively short period of time. In this DX application, there were several issues to overcome during the execution of reformation but finally the goal of this attempt has been attained by improving the process and increasing the profit. This has proven that appropriate application of the DX is useful and provides a powerful tool for improving business. Typical successful results are: 1) Service time has increased to 24 hours a day and 365 days a year. 2) Number of workforce has decreased from 37 to 27, and 3) Number of errors decreased to 1 to 4 out of 200 orders.
