The control charts of a new type known as proposed by the author in referen-ce[1] cause selecting control charts

further divide the assignable causes under Shewhart’s meaning into those to be controlled and those not to be controlled

and then can select out the former only and exert control over them

but neglect the latter. According to the number of assignable causes not to be controlled

the cause selecting control charts can be divided into the single and the multiple ones.On the basis of reference[1]

this paper offers the multiple cause selecting control charts illustrating its computing methods and theoretical basis.The multiple cause selecting control charts are more flexible and more adaptable than the single ones

and it is possible to reduce the computations of cause selecting control charts in their applications.
