The stability of the Master Production Schedule (MPS) is a critical issue in managing production operations with a Material Requirements Planning System. One method of achieving stability is to freeze some portion or all of the MPS. While freezing the MPS can limit the number of schedule...

By modifying the method of projection, the results of Hajek and Huskova are extended to show the asymptotic normality of signed and linear rank statistics under general alternatives for dependent random variables that can be expressed as independent vectors of fixed equal length. The score...

Investigation of more accurate and efficient methods of estimating the allowance for doubtful accounts was begun in the early 1950's by R. M. Cyert and R. M. Trueblood [Cyert, R. M., R. M. Trueblood. 1957. Statistical sampling techniques in the aging of accounts receivable in a department store....

In linear programming under uncertainty the two-stage problem is handled by assuming that one chooses a first set of constrained decision variables; this is followed by observations of certain random variables after which another set of decisions must be made to adjust for any constraint...

This discussion demonstrates the application of discrete optimal control theory to production planning problems. In particular we show that most of the previous models which have appeared in the literature on production planning (scheduling, smoothing and work force balancing) can be...

In an earlier issue of this journal, Charnes, Cooper, Niehaus and Stedry provided different problem formulations to take into account the multiple attributes that organizations may consider in assigning men to jobs. The present paper shows that their formulations for static multi-attribute...
