rough sets theory is a mathematical approach for analysis of a vague description of objects presented by a well-known mathematician, pawlak (1982, 1991). this paper explores the use of rough sets theory in site location investigation of buried concrete water reservoirs. making an appropriate decision in site location can always avoid unnecessary expensive costs which is very important in constr...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

Introduction: Decentralized wastewater treatment facilities are an expensive approach for developing countries. Decentralized wastewater treatment plants (DWWTPs) are a flexible technology. They have low construction and operational costs. Site selection is the most significant stage in the implementation of a DWWTPS. Therefore, the present study aimed to perform a site selection among the prop...

network location models comprise one of the main categories of location models. these models have various applications in regional and urban planning as well as in transportation, distribution, and energy management. in a network location problem, nodes represent demand points and candidate locations to locate the facilities. if the links network is unchangeably determined, the problem will be ...

purpose: the traditional view regards limb selection in reaching a hemispheric specialization and an permanent biological phenomenon. however, recent studies have questioned this idea. instead, they suggest that the task conditions is also an effective factor. the present study includes two experiments in right and left handed children examining the effect of object location as a task condition...

Warehouse location selection is a multi-criteria decision problem including both quantitative and qualitative criteria and has a strategic importance for many companies. The conventional approaches to warehouse location selection problem tend to be less effective in dealing with the imprecise or vague nature of the linguistic assessment. Under many situations, the values of the qualitative crit...
