Problem 1: Based on readings, texts, additional literature research, and class discussions, identify and expand on three benefits of conducting life cycle analysis as part of the technological product design process. Next, compare the benefits by listing and discussing three major disadvantages or challenges of performing a life cycle analysis. Try to use literature to support your argument. Solution 1: Product life cycle analysis is a systematic technique that evaluates the different stages of the product life cycle. It takes into account all the operations that the product must undergo before its manufacture and then during its use and its final disposal. LCA tries to make the assessment in terms of the impact that each process will have on the environment. LCA is a systematic and detailed approach taking into account the entire inventory of materials used in the manufacture of a product, it then assesses the environmental impacts of all material inputs in terms of discharges and thus helps decision-makers to take an informed decision.Advantages: LCA as a tool for management and policy makers: LCA helps decision makers to evaluate the different alternatives available for a process and a product and thus regulate policies based on the documented study and available measures via LCA. By quantifying the impacts of various alternatives in terms of hazardous releases to air, land and water at different stages of the life cycle, a comparison can be made between two alternative products or rival products or processes. Because LCA is a detailed analysis, all aspects of the impact of a process can be assessed. For example, if we compare two products, the amount of solid waste in one may be higher than the other...... middle of paper ......the development of sustainable technologies in other regions or how these can be blocked in the different channels. There are developments in cleaner and greener energy production techniques, such as low carbon energy production, biofuels and other recent developments in the energy sector, and how which may affect motivations for cleaner and greener technologies can be included in today's study. ://www.eebguide.eu/?p=925 http://www.solidworks.com/sw/docs/SW2014_Datasheet_Sustainability_ENU.pdf http://www.stonecourses.net/environment/benelca.html http://www.stonecourses.net/environment/benelca.html http://www.eebguide.eu/?p=925 .epa.gov/sustainability/analytics/life-cycle.htm http://www.quantis-intl.com/life_cycle_assessment.php http://link.springer.com/article/10.1007/BF02978456?no-access=true https://engineering.purdue.edu/cdesign/wp/?p=308 http://www.mel.nist.gov/msid/conferences/talks/kramani.pdf
