 Abstract:
 Nickel is one the resources that often used by humans with its use increasing from each year. In order to increase nickel production, an integrated optimum system ne...

Inventory of raw materials is the initial process in planning and controlling production. Because by materials, it becomes one processes to produce an optimal production system. In order for material inventory be controlled, MRP method used its completion. case study at CV Ajax Sport, known that using produces value Rp. 139,911,944,- 12 weeks, with number orders F300 as many 71,716 units G300 6...

Material requirements planning (MRP) is an old field but still now plays an important role in coordinating replenishment decision for materials/components of complex product structure. As the key part of MRP system, the multilevel lot-sizing (MLLS) problem concerns how to determine the lot sizes for producing/procuring multiple items at different levels with quantita‐ tive interdependences, so ...

Purpose – To develop a methodology to augment enterprise resource planning (ERP) systems with the discrete event simulation’s inherent ability to handle the uncertainties. Design/methodology/approach – The ERP system still contains and uses the material requirements planning (MRP) logic as its central planning function. As a result, the ERP system inherits a number of shortcomings associated wi...

The Bacillus subtilis mrp (multiple resistance and pH) operon supports Na(+) and alkali resistance via an Na(+)/H(+) antiport, as well as cholate efflux and resistance. Among the individual mutants with nonpolar mutations in each of the seven mrp genes, only the mrpF mutant exhibited cholate sensitivity and a cholate efflux defect that were complemented by expression of the deleted gene in tran...

RNase mitochondrial RNA processing (MRP) is a site-specific endoribonuclease located in both the nucleus and mitochondria of vertebrate cells. The enzyme is a ribonucleoprotein whose RNA component has been shown to be encoded by a nuclear gene. Because RNase MRP is particular in its substrate requirement, RNA-RNA interaction has been proposed as important for the cleavage reaction. A secondary ...

The current market practices for most capital equipment manufacturers provide them with some special difficulties in production management tasks. These are, mainly: 1. Design changes during the necessary overlapping of the production process. 2. Some degree of uncertainty with supplier's due dates and quality specifications accomplishments. 3. Sensibility of changes and other incidences in the ...
