A comparison of strategies to dampen nervousness in MRP systems

Article Abstract:

There are different ways of evaluating the quality of strategies directed at the problem of nervousness or order instability for Material Requirements Planning(MRP) systems. Nervousness can be partly disruptive in multi-level manufacturing processes when there is a new order size or the level of timing changes. The article presents and examines five different techniques for treating nervousness resulting from the interaction of decisions made on lot-sizing and on the planning horizon.

Carlson, R.C. A Lot-Sizing Algorithm for Reducing Nervousness in MRP Systems

Article Abstract:

The Wagner-Whitin (1958) algorithm is modified to dual with nervousness problems in materials requirements planning. Nervousnes means frequent changes in due dates or manufactured items. A wide variety of nervousnes situations may be covered with the modified algorithm. There is a potential for wider use. Tables are given.

A Lot-Sizing Algorithm for Reducing Nervousness in MRP Systems

Article Abstract:

The problems of nervousness in Material Requirements Planning (MRP) Systems is studied. A generalized solution methodology was developed for dealing with problems in which new setups are added to production schedule and existing setups are cancelled. Tables describing several problems are included.
