Maintenance and repair contract (MARC)
The MARC are maintenance contracts with the equipment
manufacturer which include guaranteed availability and…….
� Cost per Hours (CPH)
Here comes the customer question of…..
� ¿ It is a fair and reasonable price?
� ¿ Where can you get it?

The methodology is developed to respond questions and provide
and important tool to mining companies to make a decision
� Provide information necessary to conduct a negotiation
process with the equipment manufacturerprocess with the equipment manufacturer
� Baseline in case you can use own maintenance or mixed
maintenance (external/internal service)

Knowledge management
This methodology proposes in some stages the information from
the manufacturer of the equipment
The realization of an interrelation corresponding to integration
of information that includes an enrichment of information withof information that includes an enrichment of information with
values, points of view and experience
Step Description Knowledge management
1 Equipment model definition Information
2 Parts, operation and maintenance manual Informaction
3 Disassembly of major and minor componets (60 to 100 item) Information + interrelation=
Knowledge
4 Costs and frequency of change of new components Information
5 Costs and frequency of change of repair components Information + interrelation =
Knowledge
6 Replacement strategy for each disassembly (step 3) Information + interrelation =
Knowledge
7 Review of duplicity of costs by sub-components Information + interrelation =
Knowledge
8 Cost per hour (CPH) Information
9 Sum of cost per hour (CPH) Information

Methodology
(Step 1 to 9)
Evaluation period 10 years
Loader Wxx Base line + 0,6 %
Loader 9xx Base line + 8,7 %
Difference between proposed methodology and MARC
Electric truck Base line - 4,7 %
Mechanical truck 7xx Base line + 8,9 %
Evaluating the methodology for 2 models of equipment of 2 different
brands, this is considered to have a difference between – 5% to + 10%
which is considered reasonable as an estimate

Benefits
� It allows obtaining information from the equipment to make a
better technical-economic evaluation
� Captures the experience of the experts in equipment
� It allows to tabulate the expenses by changes of components
in detail form allowing a better projection
� To know if the cost per hour (CPH) is appropiate to the
equipment
Requirements
� To have the right staff who can be able to share experiences,
different points of views. Moreover, make relationship
between information and knowledge
