Our Co, Ltd. manufactures and sells generators. We not only distribute generators to rural areas but also provide services the difficulties after distributions. If some difficulties happen, we have to go there very often. We also sell generators in showrooms from rural areas. We had to plan to upload the location of our generator showrooms and used GIS and GPS maps from DPS because we want to know about the report step by step. After using these devices, we can work systematically more than before and DPS has also provided services for a long time.
