in this paper, we study wsn design, as a multi-objective optimization problem using ga technique. we study the effects of ga parameters including population size, selection and crossover method and mutation probability on the design. choosing suitable parameters is a trade-off between different network criteria and characteristics. type of deployment, effect of network size, radio communication...

In this paper, we propose a Software-as-a-Service (SaaS) infrastructure for industry logistics, which is normally constructed with the technology of SOA. We then propose a logistic cloud and design with service pools in it and discuss with some related works and references discussions. In the last section, we implement a SaaS-based global logistic tracking system (SGLTS) structure by abstract t...

The research project entitled Design and Management of Global Supply Chains (GLOBOP) focuses on the specific model configuration stages with productive multi location and new productive implantations, which affect the design of productive and logistic systems, and the associated supplier network design. This research project aims to offer a methodological and technical solution for those compan...

The four-parameter logistic model is often used to describe dose-response functions in many toxicological studies. In this study, under the four-parameter logistic model, optimal designs to estimate the EDp are studied. The EDp is the dose achieving p% of the expected difference between the maximum and the minimum responses. C-optimal design works the best for estimating the EDp, but the best p...

If language users are rational, they might choose to structure their utterances so as to optimize communicative properties. In particular, information-theoretic and psycholinguistic considerations suggest that this may include maximizing the uniformity of information density in an utterance. We investigate this possibility in the context of syntactic reduction, where the speaker has the option ...

background: we designed an algorithmic model based on the logistic regression analysis and a non-algorithmic model based on the artificial neural network (ann). materials and methods: the ability of these models was compared together in clinical application to differentiate malignant from benign breast tumors in a study group of 161 patients' records. each patient’s record consisted of 6 s...

a design discharge is an important issue in the design process of pressurized irrigation networks. underestimating the desing discharge affect, the required pressure and offtake discharge, increase the cost of the network. because of the lack of a standard and reliable method for this propuse, usually different approches are used by designers. the network fails to provide the required flow rate...

Distribution network design as a strategic decision has long-term effect on tactical and operational supply chain management. In this research, a supply chain design problem based on a two level capacity location allocation problem (TLCLAP) is presented. A product must be transported from a set of seaport to meet stores demands, passing out by intermediate warehouses. The objective is to locate...
