Newport Crude Oil Tank Farm Program Fuzzy Optimization

The investment decisive-making for Harbor engineering is a very complicated process, and it comes down to many fuzzy factors. Compared with the traditional investment techniques, the technique of fuzzy optimization can more effectively quantify various kinds of fuzzy factors that influence analysis and decision-making. The analytic results can be more faithful to reality and enhance scientific and accuratedecision-making.The essay is based on a true engineering project. From the selecting of influential factors, to compiling of available options, we can finally choose the best solution through evaluating various available options for deciding the location of Xingang crude oil tankers zone applying the fuzzy optimization technique. From the viewpoint of method, the first step is to determine the available investment options or opportunity set of the locations of crude oil tankers zone involving some six representative factors such as the unit engineering expense, unit operating cost, constructing period, the location land features, unit constructing engineering amount, unit land opportunity cost. These factors stem from the economic, societal and environmental regulations and rules. The second step is to specify how to choose among these available options. We have now three available options: TaoYuan, Xi Shan and Filling Sea. The third step is to establish the relative optimal matrix based on preferablerelationship and weight set of various influential factors, to evaluate every unit of the opportunity set using fuzzy dynamic programming technique. Finally we can choose the optimal option: TaoYuan. It can be learnt from the decision-making process that many project designs involving the similar problems in harbor engineering can be adopt fuzzy analysis technique to quantify fuzzy factors and provide fundament and methods for scientific decision-making.We can deduce from above that fuzzy optimization technique is a practical application of a new programming method. It is of realistic importance to increase the scientific and accurate decision-making through applying the fuzzy optimization technique for the investment decision-making of harbor engineering. Fuzzy optimization technique has a bright future as a new method used in reality.
