Step 4: Determining the sum of each row and the sum of each column.
The results were the total effects (R i +C j ) exerted and received by each factor and the new
difference (R i C j ) that contributed by each factor to the system can also be determined; they
are presented in Table 15.8.
Step 5: Determining the weight of each influential factor.
The weight of each influential factor can be determined (also see Table 15.8).

Step 6: Drawing the IRM (influence relation map).
The influence relation map is presented in Fig. 15.1. It is apparent that there are five causal
barriers, and they are: lack of advanced technologies (T 1 ), lack of special research and devel-
opment (R&D) funding (EC 3 ), lack of awareness and perceptions (SM 1 ), lack of supporting
policies and regulations (SM 2 ), and the unclear responsibility in administration (SM 3 ). The
other four barriers, including high energy consumption (T 2 ), high capital cost (EC 1 ), high
production cost (EC 2 ), and negative environmental impacts (EN 1 ) are effect barriers.
