The LCC module allows users to define life cycle costs other than
those predicted by the RCMCost and AvSim modules. These costs may
be integrated with predicted costs in the LCC cost breakdown
structure to provide a time-dependent analysis of a system's whole
life cycle cost process.
The items may be further subdivided until the cost of each element
can be defined as a mathematical equation. At a simple level this
can be the number of man-hours multiplied by a cost rate. The
elements of cost will then be added together to give the total cost
for each item and a grand total for the system through its full
life. Life Cycle Cost analysis is used to evaluate the through-life
cost of new plant or equipment. The user builds a hierarchical Cost
Breakdown Structure (CBS) through an unlimited number of indenture
levels, starting at the conception stage and continuing through
research and development, design, operations and maintenance and
ending with system disposal.
The CBS can be directly linked to cost predictions produced by
the RCMCost or AvSim modules. Other costs may be defined as
time-dependent cost equations or simple numerical values. Global
variables may be defined and utilised in the cost equations.
High level costs are determined either by summating the cost
values for child nodes in the CBS or by applying a user-defined
cost equation. The syntax of cost equations is easy to understand
and the construction of cost equations is assisted by an
intelligent code-recognition utility that automatically reveals
global variable lists as the user types in an equation.
Phase-dependent cost equations may also be defined. Phases are
shared between the LCC and AvSim modules.
