abstract increase in aquatics demand is one of the major goals for production policies. hence analysis of demand structure and aquatics consumption patterns is very applicative and useful for policy makers. using the almost ideal demand system (a.i.d.s), the demand function for types of aquatics and chicken meat in urban and rural societies in kerman city were estimated. applying time series da...

This paper studies the impact of demand-prioritization on Space-Division Multiplexing Elastic Optical Networks (SDM-EON). For this purpose, we solve static Routing, Modulation Level, Spatial Mode, and Spectrum Assignment (RMLSSA) problem using 34 different explainable strategies. Although previous works have applied heuristics or meta-heuristics to perform demand-prioritization, they not focuse...

it is necessary to consider the impact of demand uncertainty to model the comprehensive approach for supply chain network design. this paper presents four echelons, multiple commodity, and strategic–tactical model for designing supply chain network. uncertain demand, transportation mode selection with lead time configuration has been considered. a numerical example has been implemented to verif...

We apply the Weber-Fechner’s law, which represents the relation between the magnitude of physical stimulus and the magnitude of psychological sense in human being, to the utility function. We conclude that the utility function of n-types of goods is of separable type u(x1, x2, · · · , xn) = u1(x1) + u2(x2) + · · · + un(xn), which give the relation of the demand function in the form pi = dui/dxi...
