Question # 02
Economic Life may be defined as the productive life of an asset, project etc. The project concept is widely used, too, perhaps, with different meanings in subjects and areas as different as can be administration, engineering, economics, public law and science social. Each area attributed a different meaning it difficult to understand the term in a uniform way on all those who at some point we employ them. In this way it is used both to describe activities of a noun, mainly concrete physical units, civil works or plants industrial, to denote social, public health, education or similar. In this sense, expressions such as: Project Agriculture, Project Engineering, Project Investment, Transport Project Urban Life Project, Bill, Etc. The project definition: A unit of investment to build capacity producing goods or services, consistent from a technical and economic and can develop independently of other investments. It is an example of the interpretation of projects sense of investment project similar to the World Bank and the institutions under the United Nations Organization to assess development projects.

So Model A is better because its cost is only $500, while model B life cycle cost is about $1900.
Develop a general model that can be used to calculate the LCC for a car
When it comes to developing model for the calculation of Life cycle cost, there is no rocket science for it. It is obvious that the LCC evaluation is important when choosing the equipment, but it must be tailored to the type of equipment and application. This is not a quick comparison that can be used during a negotiation framework or submission process. You must first make sure you measure the current LCC and you do not just create comparative figures do not reflect the true cost of operating the equipment.
Calculating LCC traditional, if not used properly, can also penalize many theoretical concepts that have proven to significantly reduce operating costs and yield losses resulting from wear. For modeling the benefits of LCC, users must consider all costs, including operating costs, the cost of blockages and increased energy costs resulting from wear (yield ...
