Analysis of lumpiness phenomenon in MRP

Occurrence of chaotic behaviors because of fluctuations creation and their intensified transfer along the chain is one of the main causes of inefficiency of Material Requirements Planning (MRP) based supply chains. One of the reasons of the inefficiency is the lumpiness phenomenon. Through this phenomenon, some parts have an irregular production schedule, with nothing produced in some periods a...

Research of Optimization Algorithm about Multi-objective MRP and CRP

The efficiency of ERP is usually depressed because current algorithms, which just consider product requirement and stock factors but do not take whole correspondence between productive situation and resource into account, make CRP built on MRP and the resource of enterprise inconsistent so that MRP need be rebuilt. This paper takes integrated optimization of MRP and CRP as research intention, b...

Topic: Lean and Demand Driven MRP Lean Finds a Friend in Demand Driven MRP (DDMRP)

Deep Interactions with MRP

Using multilevel regression and poststratification (MRP), we estimate voter turnout and vote choice within deeply interacted subgroups: subsets of the population that are defined by multiple demographic and geographic characteristics. This article lays out the models and statistical procedures we use, along with the steps required to fit the model for the 2004 and 2008 Presidential elections. T...

Interactions between subunits of Saccharomyces cerevisiae RNase MRP support a conserved eukaryotic RNase P/MRP architecture

Ribonuclease MRP is an endonuclease, related to RNase P, which functions in eukaryotic pre-rRNA processing. In Saccharomyces cerevisiae, RNase MRP comprises an RNA subunit and ten proteins. To improve our understanding of subunit roles and enzyme architecture, we have examined protein-protein and protein-RNA interactions in vitro, complementing existing yeast two-hybrid data. In total, 31 direc...
