Model mismatch in multi-objective optimisation and preservation of trade-off order.

A multi-objective resource-constrained optimization of time-cost trade-off problems in scheduling project

This paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. The net present value (NPV) maximization and making span minimization are this study objectives. And since this problem is considered as complex optimization in NP-Hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Presenting a Multi-Objective Mathematical Model for Time-Cost trade off Problem Considering Time Value of Money and Solve it by MOPSO Algorithm

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...

Resource-awareness and trade-off optimisation in P2P video streaming

Recently, various P2P platforms have become widely popular tools for delivering both real-time and on-demand video services over the internet. However, these P2P TV approaches do experience some limitations, which adversely affect their performance. For instance, most P2P applications are designed to balance CPU load and memory but not network resources or vice versa. Through an experimental-ba...
