A Remark on the Smoothing Problem

In Hoffman, A. J., Walter Jacobs. 1954. Smooth patterns of production. Management Sci.1 86–91, the problem of smooth patterns of production—with which we presume the reader is familiar—a formula was found for the solution of the problem in the special case that the requirements are increasing. In this note, we point out that a similar formula holds if the requirements increase up to a certain value, then decrease.
