[naeini1] in this paper, a new method is proposed to find the fuzzy optimal solution of fuzzy multi-objective linear programming problems (fmolpp) with fuzzy right hand side and fuzzy decision variables. due to the imprecise nature of available resources, determination of a definitive solution to the model seems impossible. therefore, the proposed model is designed in order to make fuzzy decisi...

With the development of social spiritual civilization, people pay more and attention to physical health. The construction sports facilities is an important way improve national quality, which helps promote exercise. So, demands around world are in climax. blind crazy expansion can alleviate people’s demand for exercise a certain extent, but there also risks environmental damage economic waste. ...

This paper presents a Taylor series approach for solving linear fractional de-centralized bi-level multi-objective decision-making (LFDBL-MODM) problems with asingle decision maker at the upper level and multiple decision makers at the lower level.In the proposed approach, the membership functions associated with each objective(s) ofthe level(s) of LFDBL-MODM are transformed by using a Taylor s...

The purpose of this paper is to develop a new two-stage method for fuzzy multi-objective linear program and apply to engineering project portfolio selection. In the fuzzy multi-objective linear program, all the objective coefficients, technological coefficients and resources are trapezoidal fuzzy numbers (TrFNs). An order relationship for TrFNs is introduced by using the interval expectation of...

evaluating and selecting alternatives investment projects needs considering all relevant and important aspects. in traditional methods, the focus is just on tangible monetary criteria. also in the traditional methods, either all the information’s about factors must be known precisely or sufficient objective data must be available for applying probability theory. in this paper, a combinative app...
