GetResourceQtyTime( resource, start, end )
  Returns the resource qty time(work time * resource qty) from the calculated start time to calculated end time.
  The capacity can be calculated by taking the resource quantity into account.
ResourceLoadByResourceQtyTime( resource, start, end, condition )
  Returns the resource qty time(work time * resource qty) from the calculated start time to calculated end time.
  The load can be calculated by taking the resource quantity into account.
ResourceLoadIF ( resource, start, end, condition )
  Returns the resource load of use instructions filtered by condition expression from the calculated start time to calculated end time.
  If there is no operation, the value will be 1, and if the load is 100%, the value will be zero.
