Study of inventory management based on triangular fuzzy numbers theory

In order to deal with the problem that demand, ordering cost and holding costs which are all uncertain are neglected in the inventory management area, inventory management problem with multi-fuzzy variable under uncertainty is studied. Firstly, the uncertainty existing in inventory management is described by fuzzy theory, then, an inventory cost mathematical model which includes many fuzzy parameters is set up. Secondly, the Signed distance is used to de-fuzzify the objective function. At last, by giving a demonstration, solving inventory problem with fuzzy method is more reasonable and feasible to the reality when uncertainty is considered, and is executive and useful in the real world.
