Optimized material requirements planning for semiconductor manufacturing

Journal of the Operational Research Society, 2012
This paper describes a custom operational research algorithm, which is run nightly by IBM to create a material requirements plan for its semiconductor fabrication facility in Vermont, USA. To model alternative manufacturing processes and part substitutions, this application interweaves linear programming and heuristic methods to reap the benefits of ...

The Impact of Material Requirements Planning and Distribution Requirements Planning on Materials Management

1989
Material requirements planning (MRP) and distribution requirements planning (DRP) have been two of the most significant developments in production control and materials management for the past several decades. Other scheduling and control concepts and methods now being developed are based on these systems.

Determining Net Requirements for Material Requirements Planning

Journal of the Operational Research Society, 1991
This paper presents a design guideline for netting systems that determine net requirements, for push-type production ordering. Two alternative netting systems (full and single) are formulated in an N stage production and inventory system. The performances of the two alternatives are discussed through numerically analysing production ordering variations

Fuzzy Material Requirement Planning

2010
In this paper, we mainly discuss the convenience of incorporating fuzziness into material requirement planning (MRP) systems. Then, we formulate a MRP model in fuzziness environments. Customer demands and capacity data are assumed to be fuzzy, which is more appropriate in this model.

Fundamentals of material requirements planning

Management Research News, 2001
Outlines the concept of material requirements planning (MRP), showing how the tool offers management the capability to identify the products that were actually going to be produced. Explains how the system formalized and integrated various production and strategic requirements while quantifying usable output in an efficient manner.

Hierarchical material requirements planning

International Journal of Production Research, 1981
Abstract This paper reports on a simulation study of hierarchical planning methods, which can be utilized in connection with material requirements planning. The company considered produces one final product having a complex structure. The factory is functionally organized. Two different cases have been studied.
