This software allows users to calculate the life cycle cost (LCC) of equipment based on reliability, maintainability, and availability models. It accepts cost inputs like acquisition, operation, maintenance, and other costs. The LCC is calculated as the sum of these costs minus any revenues. The software contains modules for equipment data, cost calculation, sensitivity analysis, report generation, and more. It uses mathematical formulas and simulations to analyze how the LCC would be impacted by varying parameters over the life of the equipment.

1. Predicting the Life Cycle Cost
using Mathematical and
Software Models

2. Introduction
• This Software is used to calculate the Life Cycle Cost (LCC) of an equipment based on
Reliability, Maintainability, and Availability using appropriate methods to simulate, which
would otherwise have to be done manually and is difficult to analyze.
• This tool helps to analyze the LCC based on various governing parameters like Acquisition
Cost, Operational Cost, and Maintenance Cost etc.
• Various reports can be generated using this software for good decision-making
• The software is developed using J2EE and MySql
• The software is developed with the applicable mathematical formulas. Costs are derived or
calculated with a given cost estimating methods

3. Description
• The Software is designed to map any given system architecture into corresponding cost
elements based on reliability, availability and maintainability of the components.
• Each part of the system is configurable in its subcomponents and the importance of any
component in estimating the cost of system can be identified.
• To estimate LCC of an equipment, the tool accepts the cost inputs such as acquisition,
operation, maintenance and other costs of the equipment.
• The LCC of equipment is the sum of the Acquisition Cost, Operational Cost, Maintenance Cost
and Other Costs. Any revenues accrued shall be deducted from the LCC. LCC is calculated for
various parameters like operating hour per year etc. Where ever applicable the calculations
are done by considering inflation rate

4. Description contd..
• The system uses database for storing the information related to various cost elements of
various equipments and also provides a data base for equipment details.
• Generally LCC is done by a particular scientist at a given point of time, hence data base is
created with author name (scientist) as the main element to retrieve the details of the
equipment, costs etc.
• The software contains several modules. They can greatly enhance the calculation the LCC of
an equipment or system. Users can choose these modules according to their needs to
calculate the LCC of a system
