The abstract is accepted in the track 3.
Some comments need to be considered when writing the paper, which are:
- The author need strong support when used word like (lack).
- The author need to mentioned in some word which research method will bed used in the abstract.
- As we know there are life cycle assessment and Life cycle costing, but life cycle phases should be clarified because the author mentioned on the 2nd last sentence ( Results demonstrated that operation and manufacturing phases ....) what does it mean by manufacturing?. Is the assessment from product manufacturing or he/she means maintenance through building life cycle.
