· A life cycle cost analysis is important when making decisions about capital equipment (replacement or new acquisition) (Lee 2003 ), it reinforces the importance of locked in costs, such as R&D, and it offers important benefits. We concentrate on techniques for LCCA in Section 6.3 of this Chapter. Fig. 6.7.

According to the results obtained from the optimization curve, the absolute ORT of the drilling machine at the case study’s mine is 115 months of operation. However, the ORT has a practical range of 110 to 122 months, during which the total ownership cost remains almost constant.

This two-day course provides participants with a solid foundation in the application of life cycle costing (LCC) methods to mining plant and equipment. It focuses on teaching participants how to use LCC principals to solve real world problems and to assess investments using reliability financial modelling and sensitivity analysis.

· In accounting, life cycle costing involves gathering all the expenses an asset will generate throughout its existence. This encompasses the initial investment, future additional investments, recurring annual costs, and disposal expenses. Efficiently managing an asset’s life cycle enhances its longevity and functionality.

· The answer is that TCR C OS and TCR M OS represent different cost concerns, and both of these concerns are important under different circumstances. For example, machine A’s ownership cost is $160,000 with designed service time of 80,000 h, and machine B’s ownership cost is $120,000 with designed service time of 50,000 h.
