Order inserting problem based on fulfilling difficulty coefficient

With constraints of production capacity and limited resources,the increasing of customer＇s in- dividuation demand and uncertain factors lead to order inserting. And in decision of order variation pro- duction priority is a key issue. In order to ensure the problems encountered in inserting decision to be better solved, the concept of fulfilling difficulty coefficient was introduced in this paper. Based on this, an effective method of two-step goal-programming model for multi-attribute decision making was put for- ward and experienced. Firstly, the fulfilling difficulty coefficient was calculated with the method of grey relation analysis. Secondly,optimization model was established with the goal of minimizing the deviation between order comprehensive weight and influence factorst weight, At last,comprehensive order weight vector and order inserting sequence are respectively obtained.
