The early road to material requirements planning
Material requirements planning (MRP) systems became a prominent approach to managing the flow of raw material and components on the factory floor in the late 20th century. Its adoption was not an over night phenomenon, but was a slow progression over many decades. This article chronicles many developments and events during the formative years of MRP, highlighting changes in computer technology ...
متن کاملNet Change Material Requirements Planning
Defined and evaluated are concepts and characteristics of net change, a method that facilitates replanning and provides timely response to chunge in a transaction-oriented system. (MRP) entail an inherent massive data-handling task. Consequently , batch-oriented MRP systems tend to be untimely in their response to change since replanning can be done only periodically at best, probably once a we...
متن کاملFocusing material requirements planning (MRP) towards performance
This paper looks at the successes and disappointments of MRP. It studies numerous articles to determine what the key shortcomings of MRP are. Next, it investigates if these failures are correctable, and what the consequences of not correcting these de®ciencies means. This article considers alternatives that have been discussed in the current literature. Last of all this article discusses whethe...
متن کاملMaterial planning for production kits under uncertainty
A kit is a specific collection of components and/or tools needed for completing a procedure or producing a product. A multiperiod material planning system for production kits under the demand and procurement lead-time uncertainty is considered when component sharing among kits is plausible. Simulation experiments show that component sharing improves the system’s service measure of average kit a...
متن کاملCrop succession requirements in agricultural production planning
A method is proposed to handle crop succession requirements when determining the cultivated areas of n crops for a planning period of T years. For each year, the decision variables represent the areas where a sequence of m crops is cultivated, m ≥ 1. Here, m + 1 is the length of the longest forbidden sequence of crops not containing any forbidden subsequences. The crop succession constraints ar...
