In this paper the application of a hierarchical fuzzy system (HFS) based on MPSS and SVC in multi-machine environment is studied. Also the effect of communication lines active power variance signal between two ∆PTie-line regions, as one of the inputs of hierarchical fuzzy multi-input PSS and SVC (HFMPSS & SVC), on the increase of low frequency oscillation damping is examined. In the MPSS, to ha...

Planning of sewer systems typically involves limitations and problems, regardless whether traditional planning methods or optimization models are used. Such problems include non-quantifiability, fuzzy objectives, uncertainties in decision-making variables which commonly applied the any process. Particularly, have prevented inclusion these models. Consequently, theoretical optional solution math...

Environmental management and planning problems cover important real life areas. These problems may include the scarcity of groundwater resource, the optimality of a multi-reservoir system, the management of forest resources, the air quality monitoring networks, the municipal solid waste policies, etc. Management and planning targets by authorities consist in allocations at appropriate places an...

Process planning is an activity for designers to evaluate manufacturability and manufacturing cost in the early design stage of mechanical parts production where important parameters that affect the machining process should be analyzed in detail. This paper deals with the systematic determination of the detailed methods involved in the manufacturing of parts from raw materials to a finished pro...

a theorem was recently introduced to establish a relationship betweengoal programming and fuzzy programming for vectormaximum problems.in this short note it is shown that the relationship does not exist underall circumstances. the necessary correction is proposed.

This paper investigates the optimization problem of multi-product aggregate production planning (APP) with fuzzy data. From a comprehensive viewpoint of conserving the fuzziness of input information, this paper proposes a method that can completely describe the membership function of the performance measure. The idea is based on the well-known Zadeh’s extension principle which plays an importan...

Battery storage system is emerging as an essential component of hybrid power system based on renewable energy resources such as solar and wind in order to make these sources dispatchable. Accurate modeling of battery storage system is essential in order to ensure optimal planning of hybrid power systems incorporating battery storage. Majority of the system planning studies involving battery sto...

Agriculture in Russia has some specifics such as large distribution, inclement climate and big market competition. Appearing of resources-economy, precision and management technologies demanded from agriculture companies new planning and control methods. The paper is dedicated to assembly charts planning in agriculture with multi-agent approach. For resources distribution we used method of virt...
