The increasing complexity of the enterprise has motivated the utilization of mathematical programming methodologies to deal with many of the decisions faced by companies. However, in many cases the combinatorial complexity of the decision problems is exacerbated by uncertainty in many of the model parameters, requiring the use of scenarios or stochastic programming strategies. Unfortunately, th...

For grey stochastic multi-criteria decision-making problem with criterion value as extended grey number, the study proposes grey stochastic multi-criteria decision-making approach based on Hausdorff distance. First, it provides definition and operation rule of extended grey number stochastic variable and expectation, then obtains expectation decision matrix about grey number based on grey decis...

environmental factors are one of the most sensitive issues that should be considered in many decisions. site selection is one of the most widely used spatial decision making problems and is influenced by many environmental factors. the purpose of site selection is to find a set of appropriate spatial alternatives for a particular application. site selection is a multi-criteria decision making p...

Selecting an MCDM method to use in any decision-making problem is always a difficult issue regarding that there no agreement generally on which the most appropriate one. This paper addressed proposal of hybrid approach for this problem. Under assumption superiority among well-established and accepted methods, we defined maximin strategy based fact lowest correlation between MCDMs proposed terms...

multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

abstract. today, there is no specific method or criterion for selecting contractors in the researches’ field. usually this selection is regarded as a matter of taste and as a result, there is no coordinated approach in the mentioned domain. sometimes, after signing the contract, the inappropriate selection became clear. the managers are in direct need of a pattern for selecting the contractors....

information accompanied with the technology supporting it is valuable asset in many organizations. as organizations are highly depended on it, implementing it effective governance is necessary for them. it governance areas affecting business are strategic alignment, risk management, performance management, resource management and providing value.  successful performances need a mix of structure...

data envelopment analysis (dea) is a nonparametric approach to estimate relative efficiency of decision making units (dmus). dea and is one of the best quantitative approach and balanced scorecard (bsc) is one of the best qualitative method to measure efficiency of an organization. since simultaneous evaluation of network performance of the quad areas of bsc model is considered as a necessity a...
