The accelerating trend toward Faster, Better, Cheaper (FEE) missions places increasing emphas is on the trade-offs between requirements and risk to reduce cost and development times, while still improving quality and reliability. The Risk/Requirenlents Trade-off Guidelines discussed in this paper are part of an integrated approach to address the main issues by focusing on the sum of prevention,...

In common models of project time-cost trade-off, time value of money is not considered and often time-cost trade-off is performed without considering time value of money. In real world, pass of time causes decrease in money value. Therefore, taking into account the time value of money in time-cost trade-off problem makes this problem is becoming more and more realistic. In this paper, we study ...

Time, cost and quality are considered as the main components in managing each project. Previous researches have mainly focused on the time-cost trade-off problems. Recently quality is considered as the most important factor in project�s success, which is influenced by time acceleration that is the less time is spent the more success is gained. In time-cost-quality trade-off problems, each act...

Many solutions to cost-sensitive classification (and regression) rely on some or all of the following assumptions: we have complete knowledge about the cost context at training time, we can easily re-train whenever the cost context changes, and we have technique-specific methods (such as cost-sensitive decision trees) that can take advantage of that information. In this paper we address the pro...

If cost reductions produce a cost-quality trade-off, healthcare policy makers need to be more circumspect about the use of cost-effective initiatives. Additional empirical evidence about the relationship between cost and quality is needed to design a value-based payment system. We examined the association between cost and quality performances for acute myocardial infarction (AMI) care at the ho...

This article analyses the conflict between trade values and other values ('trade and ... problems'), such as environmental protection, labour rights or free competition, as It Is addressed by the principal legal devices available to address such conflicts ('trade-off devices') In the dispute resolution context In the European Union, the GATT/World Trade Organization system and In the United Sta...

Although significant private investment is absorbed in different sectors of power systems, transmission sector is still suffering from appropriate private investment. This is because of the pricing policies of transmission services, tariffs, and especially for investment risks. Investment risks are due to the uncertain behaviour of power systems that discourage investors to invest in the transm...

this paper explores the capabilities of multi-objective particle swarm optimization algorithmin a simulation-optimization model for solving waste load allocation problems. the main goals are totaltreatment costs, violation of the water quality standards and equity. in this research, the water qualitysimulation model is coupled with a multi-objective optimization model, mopso. in order to derive...
