Abstract:

The cost of spare parts takes up a large proportion of equipment maintenance cost, so it is an important factor affecting the life cycle cost of the equipment. To control life cycle cost of the equipment and improve the cost benefit, it is put forward that the procurement project of spare parts is chosen by the life cycle cost technology. The basic conception and relations among overseas procurement, domestic procurement, development and equipment substitution are analyzed. The life cycle cost models for the four procurement projects are set up. Take the procurement of spare parts of some ship imported equipment as the instance, and the sequence of the procurement projects is made by life cycle cost technique. The instance shows that the life cycle cost technique is one of the effective decisionmaking methods of spare parts procurement, which is worth application and popularization in engineering.
