Abstract: An operation management system including a controller configured to execute: a position obtaining process to obtain positional information from each registered mobility; a correlating process to correlate each registered mobility and specification information stored in a storage device with each other; a travel-history storing process to store, in the storage device, a traveled route which is a travel history of each registered mobility, so as to be correlated with map information; and a road-surface-condition obtaining process to calculate a road surface condition including a position and a shape of a rut corresponding to the traveled route based on information on a detection value of a sensor of each of registered mobility, the type of a road surface included in the map information, the specification information, and the traveled route and to store, in the storage device, the road surface condition so as to be correlated with the map information.

Abstract: A workable high strength shape memory alloys comprising:Al: 11.5-13.5%,Ni: 2-6%,Mn: 1-5%,Ti: 0.1-5%,each on the weight basis, and the balance of Cu and inevitable impurities.In the modified alloy composition, the workability can be improved without increasing the martensitic transformation temperature.
