Operation support system for construction machine and construction machine
An operation support system for a construction machine includes a memory that stores a program and a processor configured to execute the program stored in the memory to perform a process. The process includes generating multiple operation patterns or multiple arrangement patterns for the construction machine such that a rating regarding a predetermined target index becomes relatively high, obtaining environmental information of the construction machine to be supported, and outputting, based on the multiple operation patterns or the multiple arrangement patterns, an operation pattern or an arrangement pattern with which the rating regarding the predetermined target index of an operation of the construction machine to be supported becomes relatively high under an environment corresponding to the obtained environmental information.
