Process control systems

The present study draws from two major bodies of literature: (1) research on leadership, which recognizes the important role of leaders in driving organizational performance and that leadership style may differ across individuals; and (2) the MCS literature, including RM concepts, in which control systems are viewed as mechanisms to “assist the organization in managing its risk and to promote effective governance processes” (Krogstad et al., 1999, p.

The purpose of this research is to model the factors affecting a production and inventory system that combines returns and remanufacturing, and to evaluate effective control strategies in order to improve the performance of the system. In this regard, the main steps adopted to conduct the modelling process initially involved an investigation of reverse logistics and closed loop supply modelling as reported in the literature. An investigation of previous models developed contributed to our research by increasing the knowledge required to conduct the modelling.

Enterprise Resource Planning (ERP) system is one of the most popular forms of IT for businesses at present. Deriving from efforts to rationalize lead times and possession stock costs, the 80’s manufacturing resource planning (MRP II) is developed into ERP system considered as the standard that integrates business processes throughout the organization, which in turn enhances operational efficiency (Akkermans, Bogerd, Yücesan, & Van Wassenhove, 2003; Davenport, 1998). Callaway (1999) states that the ERP system promises to achieve benefits in both tangible (e.g.

In eukaryotes, pre-rRNA processing depends on a large number of non-ribosomal trans-acting factors that form large and intriguingly organized complexes. A novel nucleolar protein, Nop53p, was isolated by using Nop17p as bait in the yeast two-hybrid system. Nop53p also interacts with a second nucleolar protein, Nip7p. A carbon source-conditional strain with the NOP53coding sequence under the control of theGAL1promoter did not grow in glucose-containing medium, showing the phenotype of an essential gene. ...

Histidine-containing protein (HPr) is a central metabolic sensor in low-GC Gram-positive bacteria and plays a dual role in sugar uptake by the phos-phoenolpyruvate–sugar phosphotransferase system and in transcriptional control during carbon catabolite repression. The latter process is mediated by interaction between HPr and the carbon catabolite repression master transcription regulator, carbon catabolite protein A (CcpA), a member of the LacI-GalR family of DNA-binding proteins.

Hundreds of Thousands of $$$ Worth of Network Equipment can be Rendered Junk in a Flash! The issue of protecting networks from security breaches has attracted considerable attention but organisations also need to guard against environmental risks such as lightning. Damaged or destroyed equipment, which is integrated into manufacturing or data storage processes, can cause physical damage, as well as high consequential losses due to downtime. Lightning strikes can also delay production due to data loss and damage process control computers or computer-based warehouse and storage systems.
