assessment (LCSA). As the LCC expands from the financial LCC (fLCC) to
the environmental LCC (eLCC) to the social LCC (sLCC), the system
boundary expands and starts including activities whose financial equivalents
are increasingly uncertain. The Design-of-experiments (DOE) approach to
Global Sensitivity Analysis (GSA) provides a simple procedure to systemat-
ically determine the sensitivity of the LCC to key parameters, while taking
into account potential interactions. By doing so, a more intuitive grasp of the
relative importance of each of the parameters is provided to decision-
makers. This approach has been applied here to the case of biodiesel produc-
tion in Vietnam, but can be readily generalized to a wide range of LCC
applications as well.
