Abstract The aim of this paper is to extend the theory lower and upper solutions periodic problem associated with planar systems differential equations. We generalize previously given definitions we are able treat both well-ordered case non-well-ordered case. proofs involve topological degree arguments, together a detailed analysis in phase plane.
Optimal operation of hydropower reservoir systems often needs to optimize multiple conflicting objectives simultaneously. The conflicting objectives result in a Pareto front, which is a set of non-dominated solutions. Non-dominated solutions cannot outperform each other on all the objectives. An optimization framework based on the multi-swarm comprehensive learning particle swarm optimization a...
A Multi-objective optimization procedure has been developed to determine some kinetic parameters of free radical polymerization of vinyl acetate based on genetic algorithm. For this purpose, mathematical modeling of free radical polymerization of vinyl acetate is carried out first and then selected kinetic parameters are optimized by minimizing objective functions defined from comparing exp...
The kinetic theory of a self-gravitating system is considered in the BhatnagerGross-Krook approximation to the kinetic equation. This approach offers a unique and tractable setup for studying the central, collision-dominated region of the system, as well as its almost collisionless outer part. Stationary non-equilibrium states of the system are considered and several different self-similar solu...
design and expansion of distribution systems seems inevitable in view of the need to satisfy the rise in energy consumption in a technical and economical way. optimal location, sizing and determining the service area of substations is one of the principle problems in expansion of distribution systems. also uncertainty is one of the important factors that increase risk of exact decision makings....
In this paper, a general process is developed to find all non-dominated solutions of the multi objective combinatorial optimization (MOCO) problem. This process is based on the elastic constraints method and applies the identification of objective's bounds for it. Objectives bounds are determined by solving single objective integer programming problems. First the elastic constraints method is...
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
Solving a New Multi-objective Inventory-Routing Problem by a Non-dominated Sorting Genetic Algorithm
This paper considers a multi-period, multi-product inventory-routing problem in a two-level supply chain consisting of a distributor and a set of customers. This problem is modeled with the aim of minimizing bi-objectives, namely the total system cost (including startup, distribution and maintenance costs) and risk-based transportation. Products are delivered to customers by some heterogeneous ...
