Many roads in the United States have approached the end of their design and/or service lives. In a recent report published by the American Society of Civil Engineers (ASCE), 42% of highways in the United States are congested and cost the economy about $100 billion in wasted time and extra fuel consumption. Due to the poor condition of the national highway network, it has been given a grade “D” ...

one of the most effective tools for decline cost and time, quality improvement and consequently project performance enhancement especially in construction projects, is value engineering. there are linguistic judgments in many cases of value engineering studies in construction projects such as interior design, mechanical installations design, and etc. therefore multiple attribute decision-making...

Today mechanical engineering is one of the most dynamically developing industries. The products this industry are becoming more and complex, requiring continuous introduction new high technologies into production process. In addition, change in preferences consumers associated with an increase degree automation robotization their processes leads to need apply flexible product design approaches....

Agents and multiagent systems (MAS) have already proved suitable for dealing with the complexity of today B2B application scenarios. Application environments such as virtual enterprises (VE) and inter-organizational workflow management systems (WfMS) specially call for the integration of heterogeneous resources, services, and processes. In this article, we first recognize VE and workflow manage...

a supply chain is composed of a complex sequence of processing stages, ranging from raw materials supplies, parts manufacturing, components and end-products assembling, to the delivery of end products. in the context of supply chain management, supplier selection decision is considered one of the key issues faced by operations and purchasing managers to remain competitive. therefore, requiremen...

The minute ventilation/carbon dioxide production (VE/VCO2) slope has been widely demonstrated to have strong prognostic value in patients with chronic heart failure (CHF), and the risk of mortality is believed to increase when the VE/VCO2 slope is >32.8; however, there is little evidence concerning the prognostic value of the VE/VCO2 slope in Chinese patients. In the present study, the prognost...

Foundation work is one of the most crucial jobs in building construction. Therefore, an appropriate method needed to determine effective and efficient type foundation. One methods used paired comparison with a value engineering approach. In this case study, compare square pile foundation (existing) use triangular design round piles. The total budget Rp. 3.834.143,026,84. analysis shows that D-3...
