Life-cycle related technical-environmental multi-parameter trade-off optimization of processes.

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;...

Multi-objective Optimization of Product Life-Cycle Costs and Environmental Impacts

Environmental life cycle assessment and optimization of buildings

The work aims to present initial efforts to the development of an integrated user friendly (architect-oriented) tool for the environmental assessment and optimization of buildings. The tool will focus on the preliminary design phase, where improvements, having a major influence on the building lifecycle, are still possible. A software tool for dynamic simulation of the building lifecycle will b...

A Multi-Mode Resource-Constrained Optimization of Time-Cost Trade-off Problems in Project Scheduling Using a Genetic Algorithm

In this paper, we present a genetic algorithm (GA) for optimization of a multi-mode resource constrained time cost trade off (MRCTCT) problem. The proposed GA, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. Beyond earlier studies on time-cost trade-off problem, in MRCTCT problem, resource requirements of each execution mo...
