The selection of oil and gas exploration need to take many factors into account, so the model building of portfolio optimization must be multipurpose. According to the characteristic of oil and gas exploration, this passage applies the NAV to measure the profit of portfolio and adopts the variance of the NAV to measure the risk of portfolio, and this passage applies multiattribute evaluation to evaluate the project index to measure the portfolio profit and risk. Then this passage builds the multi-objective model to optimize and study the portfolio of oil and gas exploration.
