Conversion of fossil fuels to electrical power is the most popular method of electrical power generation. Due to the depletion of fossil fuels and the increase in air pollution, the necessity of using high efficiency power generation systems is increasing. High temperature fuel cells, such as solid oxide fuel cells (SOFC) and molten carbonate fuel cells (MCFC), have high efficiency. According t...

For linear construction projects, it has long been known that resource utilization is i]mportant in improving work efficiency. However, most existing scheduling techniques cannot satisfy the need for solving such issues. This study presents a flexible model for resolving linear scheduling problems involving different objectives and resource assignment tasks. The proposed model adopts constraint...

For planning to come of age, plans must be judged by a measure of quality, such as the total cost of actions. This paper describes an optimal-cost planner which guarantees global optimality whenever the planning problem has a solution. We code the extraction of an optimal plan, from a planning graph with a fixed number k of levels, as a weighted constraint satisfaction problem (WCSP). The speci...

This study aims to measure the production capacity and capacity utilization in pharmaceutical industry. The capacity utilization is the ratio of actual production level to the potential production level which shows the gap between real production and production capacity. Method: Through econometric methods, the short-run translog cost function is estimated with the cost share function of produ...

The maintenance strategy used in an electric power plant plays a crucial role its overall performance and operational efficiency. An effective describes the approach to exploiting various forms of (corrective, preventive, predictive, proactive, etc.) plant. In this paper, ineffective impacts strategies on plants were examined. Also, distinction between corrective, aggressive was considered. ter...

To improve the efficiency of industrial automation systems, many operators are considering the possibility of IP upgrades to provide centralised control/management and remote monitoring. When migrating to converged IP-based networks, acquiring an Ethernet communication framework will be necessary to provide higher bandwidths and longer transmission distances, which can require the installation ...

To be cost-effective, field service managers must balance the high cost of machine downtime with the high cost of cross-training technicians in multiple skills. We study a field service system with three job types requiring three different skills. Each server has a primary skill, the cost of which is considered sunk, and up to two secondary skills, which is a managerial decision. We model two i...

This study aims to measure the production capacity and capacity utilization in pharmaceutical industry. The capacity utilization is the ratio of actual production level to the potential production level which shows the gap between real production and production capacity.

The efficiency literature, both using parametric and non-parametric methods, has been focusing mainly on cost efficiency analysis rather than on profit efficiency. In for-profit organisations, however, the measurement of profit efficiency and its decomposition into technical and allocative efficiency is particularly relevant. In this paper a newly developed method is used to measure profit effi...

We propose a way to define the most expensive operation to be used in evaluations of complexity and efficiency for simulated distributed constraint reasoning (DCR) algorithms. We also report experiments showing that the cost associated with a constraint check, even within the same algorithm, depends on the problem size. The DCR research has seen heated debate regarding the correct way to evalua...
