A Survey of Concurrency Control Algorithms in the Operating Systems
Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...

متن کاملImproving Picking Productivity by Redesigning Storage Policy Aided by Simulations Tools
Order picking is defined as the process of clustering and scheduling orders, assigning stock on location to order lines, releasing orders to the floor, picking the articles from storage locations and the disposal of the picked articles (De Koster et al. 2007). Picking is the most labourintensive operation in warehouses with manual systems and a very capital-intensive operation in warehouses wit...
متن کاملCost Function Modelling for Semi-automated SC, RTG and Automated and Semi-automated RMG Container Yard Operating Systems
This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...
