Along with the technology evolution and the enormous growth in product complexity, product components are not only various in type but also unstable in the demand. Thus, the enterprise won’t be able to manufacture each component of every product by oneself. In order to upgrade the enterprise’s whole efficiency, the procurement of components needed will mainly obtained by manufacturing or outsourcing. Decision attributes which are often used are cost, time, and quality. However, in the reality, there are lots more attributes that are also important in decision making. Therefore, we need to construct a model which can consider multiple decision attributes in finding the optimal decision of component procurement. This will help the DMs (decision makers) to make accurate and efficient decision which can also meet the market needs and increase the enterprise’s competitiveness. In this research, we will construct a model of component procurement decision. In which, the goal setting and state evaluation in human behavior mechanism flow chart from habitual domains will be used as the core structure of this research. While the product structure diagram (PSD) will be used to decompose the product into components. Then, we will give a solution to the decision of component procurement by both constructing decision net and obtaining the distance value. Finally, we will also build a program of component procurement decision making in order to demonstrate the results and the examples.
