For the collection and clinical usage quantities of regional blood changing randomly, it is hard to efficiently adjust regional blood supply and demand balance extent with quantitative way. To solve this problem to some extent, a vague set based adjustment model is proposed. Blood stock level of regional blood center being chosen as expressing indicator and the ideal blood stock level interval as criteria, and considering the fuzzy characters of the indicator being subject to its criteria interval, vague set similarity measure function is applied to found a vague set based measure function for regional blood supply and demand balance extent. With the introduction of adjustment factor, derived from the measure
function, an adjustment model for regional blood supply and demand balance is established. With the application of the model, and referring to the literature published blood stock operation data of several regional blood centers in China, a determination method of the aimed lower and upper limit of blood center stock control level is obtained. The aimed lower and upper limit of blood center stock control level can be an operable reference to blood center stock operation, which is helpful for regional blood center to effectively manage its blood stock level according to different regional blood supply and demand balance goal.
