The development of a new product is complicated multi-stakeholder process with significant risk failure. This particularly true in the medical device sector, where there are strict therapeutic, psychological, and normative constraints. article presents multi-criteria decision making called “Define, Prioritize, Measure, Aggregate” (DPMA). DPMA designed to help engineering managers during devices...

We investigate the dynamic stochastic multicriteria decision making (SMCDM) problems, in which the criterion values take the form of log-normally distributed random variables, and the argument information is collected from different periods. We propose two new geometric aggregation operators, such as the log-normal distribution weighted geometric (LNDWG) operator and the dynamic log-normal dist...

in last decades, the skillful planning of land resources has become a major issue for rural development. the development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. fuzzy logic is preferred to boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can the...

one of important problems in supply chains management is supplier selection. in a company, there are massive data from various departments so that extracting knowledge from the company’s data is too complicated. many researchers have solved this problem by some methods like fuzzy set theory, goal programming, multi objective programming, the liner programming, mixed integer programming, analyti...

nowadays the quality of life is one of the factors that have special standing in the context of urban planning studies. this factor became significant due to the increasing importance of quality of life in the monitoring of public policy and its role as an efficient tool in the management and planning. urban life quality is usually measured through the surveying and evaluation of subjective per...

extended abstract introduction the widespread and great inequalities in income generation, commonwealth, job opportunities and developmental facilities between urban and rural areas, have leaded the rural population towards the decline and in some instances the rural exodus. additionally, the rural poverty and deprivation has also caused major urban crisis, due to the vast rural migration and ...

the use of value engineering (ve) methodology in construction industry has grown significantly, mainly in view of its extensive benefits. the main task in evaluation phase of ve workshop is to assess alternative ideas, proposed for each function. this phase of ve, hence, could be deemed as a multi criteria decision making (mcdm) problem. this paper presents a fuzzy decision support system (dss)...
