چکیده

In this article we propose to introduce a new selection parameter in Genetic Algorithms (GAs) for a class of constrained reliability design problems. Our work demonstrates two major points. The first one is that the populations are quickly included in the space of the feasible solutions for a sufficiently large selection of parameter value. The second one is that the value of the selection parameter controls the exploration strategy of the feasible space. These two properties illustrate that an adapted choice of the selection parameter value allows to improve the performance of GA. Furthermore, our numerical examples tend to show that, with an adapted choice of the selection parameter, these GAs are in practice more efficient than previously proposed GAs for this class of problems.

An improved genetic algorithm for multidimensional optimization of precedence-constrained production planning and scheduling

Integration of production planning and scheduling is a class of problems commonly found in manufacturing industry. This class of problems associated with precedence constraint has been previously modeled and optimized by the authors, in which, it requires a multidimensional optimization at the same time: what to make, how many to make, where to make and the order to make. It is a combinatorial,...

Reliability Optimization for Complicated Systems with a Choice of Redundancy Strategies (TECHNICAL NOTE)

Redundancy allocation is one of the common techniques to increase the reliability of the bridge systems. Many studies on the general redundancy allocation problems assume that the redundancy strategy for each subsystem is predetermined and fixed. In general, active redundancy has received more attention in the past. However, in real world, a particular system design contains both active and col...

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...
