Summary
Functional unit: 
A color computer monitor, with a screen size of 17-inch. a six-year period for the lifetime is taken in the functional uni
Goal and scope of the summary: 
The environmental performance of a color computer monitor is investigated by implementing a Life Cycle Assessment. The goal of this study is to collect LCI data of foreground systems, to identify hot spots, and to introduce life cycle thinking at the product design stage. Secondary data are used in the background system, and site-specific data are collected in the foreground system.

Results show that the use phase is the most contributing phase.

The operating mode and the energy saving mode during the

overall use phase contribute to the total by 59% and by 9.9%,

respectively. In the production phase, the cathode ray tube assembly

process and the printed circuit board assembly process

are the most contributing processes. The sensitivity analysis on

the use pattern scenario shows that the contribution ratio of the

use phase ranges from 32% to 84%. Even in the home use case,

which is the best case scenario, the use phase is one of the most

contributing processes to the environmental performance of the

color computer monitor. There is no significant difference in

the choice of the impact assessment methodologies for identifying

the improvement opportunities.

For the external use of Life Cycle Assessment in a short-run product

for the market, it is recommended that Life Cycle Assessment

should be carried out in parallel with the product design stage. It

is also necessary to have a pre-existing, in-house database for a

product group in order to accelerate life cycle procedures.

Well, this is a very amazing

Well, this is a very amazing article of the study base because through the study complete the life cycle with the passage of time. Student are needed to superior writing for completing the assignment on the daily basis. Study is very important in our life.
