Trade-offs occur frequently within sociotechnical systems and allow the system to maintain its output in the face of the variable performance of its constituent components. Trade-offs also occur between systems that must interact with each other. Some of these intersystemic tradeoffs may threaten the integrity of one or both systems particularly if the allowable magnitude of the trade-off is no...

the concept of decision making, factors influencing it and the related outcomes have always attracted researchers. the purpose of this study is to investigate the effect of sacred values on decision making, decision difficulty and the resulting negative emotions. thus, a sample of 288 students from the university of guilan were chosen as subjects and were required to complete a standard questio...

Web-based systems are software systems with a Web interface. In recent years it has successfully penetrated into our everyday life. Development of such systems has also opened a new area in software engineering: Web engineering. Many studies found that Web development often experiences much shorter cycle time than traditional software development. It conflicts with some non-functional requireme...

In this paper, the Preference Range and Uncertainty Filtering (PRUF) Method is proposed for visualizing multi-attribute design problem solutions under uncertainty. This method enables decision makers to perform real-time trade-off investigations by incorporating preference ranges and uncertainty at the input level. In a real world case, designers must consider potentially complex trade-off deci...

The analysis of trade-offs between competitive priorities is one of the core issues in manufacturing strategy research. However, past studies focused mainly on empirical validation of the trade-off concept. There has been limited research on practical aspects of trade-off management, especially methods for trade-off improvement and the incorporation of trade-off analysis into manufacturing stra...

The analysis of spectroscopic optical coherence tomography (SOCT) signals suffers the trade-off between time resolution and frequency resolution. Various joint time-frequency distributions (TFDs) can optimize this trade-off. Synthesized signals were generated and experimentally acquired data were obtained to compare and validate several different TFDs under different SOCT imaging schemes. Speci...

This research paper adapts intelligent water drops (IWD) algorithm to solve the discrete timecost-quality trade-off problem (DTCQTP) in software projects which is never solved before by this algorithm. Project manager's goal is getting an optimal allocation of time, cost and quality of each task/activity in the software project such that total time and cost of the project is minimized while pro...

We consider the well known problem of finding two identical elements, called a collision, in a list of n numbers. Here, the (very fast) comparison based algorithms are randomized and will only report existing collisions, and do this with (small) probability p, the success probability. We find a trade-off between p and the running time t, and show that this trade-off is optimal up to a constant ...

The time - cost tradeoff problem is one of the most critical issues in the project scheduling field and so far, a lot of research has been done with a variety of quantitative and qualitative approaches on this subject. In this research, we intend to provide a two - objective mathematical model which balances crash and delay for activities. So that it provides the right tools for decision makers...
