Eco-efficiency is generally defined as the ratio of an economic and environmental variable. This interpretation also cited in connection to its most popular implementation, known “BASF eco-efficiency portfolio analysis”. There is, however, something strange about this. A easily visualized a slope, but BASF’s method working with distance, which can be formulated weighted sum, not ratio. Upon clo...

Data Envelopment Analysis (DEA) is an eciency measurement tool for evaluation of similar Decision Making Units (DMUs). In DEA, weights are assigned to inputs and outputs and the absolute eciency score is obtained by the ratio of weighted sum of outputs to weighted sum of inputs. In traditional DEA models, this measure is also equivalent with relative eciency score which evaluates DMUs in compar...

The role of the information technology is growing rapidly in the world of business, to communicate with the customers effectively. Computer network is the back bone of any organization. It helps in effective utilization of resources such as time, money etc. Server plays an important role in the network, to store the data. A wide variety of servers exist in the market. This paper focuses on the ...

This paper presents a new method for scalarization of nonlinear multi-objective optimization problems. We introduce a special class of monotonically increasing sublinear scalarizing functions and show that the scalar optimization problem constructed by using these functions, enables to compute complete set of weakly efficient, efficient, and properly efficient solutions of multi-objective optim...

Long-term forecasting of key macroeconomic indicators such as population is very important for future development policy-making. Population plays an role in economic decision-making, social security and growth. So it to develop a good model predicting indicators. In order improve the growth model, we introduce new called Exlog Weighted Sum Model This combines both exponential logistic models. T...
