A business process is generally defined as a network of activities that uses resources to transform inputs into outputs with an overall goal of satisfying customer requirements. Companies are being driven to design new business processes and to improve existing ones by increasing competition in a global environment. And the importance of a process focus creates a need for structured approaches ...

Saccharamyces cerevisia known as baker’s yeast is a product used in various food industries. Worldwide economic competition makes it a necessity that industrial processes be operated in optimum conditions, thus maximisation of biomass in production of saccharamyces cerevisia in fedbatch reactors has gained importance. The facts that the dynamic fermentation model must be considered as a constra...

Sexual selection is the mechanism that favors an increase in the frequency of alleles associated with reproduction (Darwin, 1871). Darwin distinguished sexual selection from natural selection, but today most evolutionary scientists combine the two concepts under the name, natural selection. Sexual selection is composed of intrasexual competition (competition between members of the same sex for ...

In this paper a new form of duality for probabilistic cellular automata (PCA) is introduced. Using this duality, an ergodicity result for processes having a dual is proved. Also, conditions on the probabilities defining the evolution of the processes for the existence of a dual are provided. The results are applied to wide classes of PCA which include multi-opinion voter models, competition mod...

there are many agreements for transferring technology, but license agreement is the most important agreement in this regard. according to the mentioned agreement, the owner of patent or technology as licensor grants the license to licensee in specific duration and in a given territory. exclusive rights of licensor and the objectives of competition law, including the welfare of consumers or prev...

The Trading Agent Competition (TAC) is an international forum which promotes high-quality research regarding the trading agent problem. One of the TAC competitive scenarios is Supply Chain Management Procurement Challenge (SCM-PC) where three agents compete by buying components, assembling PCs from these components and selling the manufactured PCs to customers. The idea of SCM-PC is the develop...

Evolutionary processes proved very useful for solving optimization problems. In this work, we build a formalization of the notion of cooperation and competition of multiple systems working toward a common optimization goal of the population using evolutionary computation techniques. It is justified that evolutionary algorithms are more expressive than conventional recursive algorithms. Three su...

This paper presents simulations of long-term co-evolution in simple artificial ecosystems composed of different plant species. Artificial plants and plant communities, evolving in a 3D environment, are based on a multi-agent model. This multi-agent approach allows to define communication processes existing at plant and organ levels. A model of a particular chemical interaction between plants is...

We present a hybrid method to efficiently solve Google Machine Reassignment problem (MRP), the problem proposed at ROADEF/EURO Challenge 2012 competition. We study, implement, combine and empirically examine different local search neighborhoods to solve the set of available instances. Intensification and diversification of search is achieved through the suitable change of the objective function...
