Abstract Non-informatics cost estimation is a tedious process and requires substantial amount of time manual operations. However, BIM adoption approaches have attracted significant attention with this respect. Since models are object-based built-in parametric information, it easier to capture the quantities building elements deliver more accurate estimates less errors omissions. As most current...

cellular manufacturing system is one of the most important applications of group technology. design of this system involves many structural and operational issues, in which the cell formation and production planning are two important steps. in this paper, a new mathematical model is proposed for integration of cell formation and production planning problems with the aim of minimizing the overal...

Squirrel-cage induction motors play an important role in the world’s industry. Hence there is a strong demand on their reliable and safe operation. Their faults and failures can lead to excessive downtimes and generate enormous costs due to reduced output, emergency maintenance and lost revenues. In this paper a FEM model of a three phase squirrel-cage induction machine is presented. It is used...

In this paper we present a new approach to benchmark the performance of shared memory systems. This approach focuses on recognizing how far off is the performance of a given memory system from a realistic ideal parallel machine. We define such a realistic machine model called the z-machine, which accounts for the inherent communication costs in an application by tracking the data flow in the ap...

This paper reports on a configuration for Virtual Desktops (VDs) which reduces the total hardware cost to approximately $32.41 per desktop, including the storage infrastructure. This number is achieved using a configuration with dual node, cross-mirrored, High Availability storage. In comparison to previously published reports, which tout the storage infrastructure costs alone of VDI at from fi...

Capital cost, resale value and running cost including maintenance costs, repairing costs, and operation costs of equipment are considered as crisp numbers in ordinary replacement problem. Nevertheless, in a special situation such as operating military equipments during wartime, the working efficiency of the machine and its related costs are no longer crisp but uncertain. This uncertainty can be...

The Controlled English we have developed for Caterpillar is designed to reduce translation costs by facilitating machine translation. It is also preferred by English-speaking readers of the resulting documents. The approach to machine translation and the resulting design of the Controlled English were optimized to Caterpillar's environment and requirements, including a very high document and tr...

This paper describes the implementation of an integrated monitoring system for a CNC machine tool and its machining processes such as drilling, milling, turning and grinding. The monitoring system uses a variety of sensors such as force, torque, vibration, acoustic emission, and temperature to monitor the machining processes and the physical condition of the machine tool. The major aim is to im...
