background: healthcare authorities, in all around the world, are faced with resources limitations and limitless needs of citizens. therefore, optimal resources allocation, particularly in the health sector and emergency system, seems to be of great importance. the present study aimed to determine the optimality rate of patients' distribution to hospitals by emergency stations based on the trans...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...

optimal allocation of water resources is an essential service in agriculture that must be considered by farmers. one of the most significant factors in optimal allocation of water resources in agriculture is to define optimal farm cropping pattern. in this study, in order to determine optimal cropping pattern and water resources allocation in central district of mashhad city (toos village), the...

A health authority chooses a binary action for each of several individuals that differ in their pretest probabilities being infectious and the additive losses associated with two types decision errors. The is endowed portfolio tests sensitivities specificities. We derive simple necessary condition optimality test allocation. In special cases, precision parameters allocated are monotone individu...

the optimal allocation of the chahnimeh water resources among different sectors, viz. domestic, agricultural and environmental consumptions, was determined using the goal programming method in gams, based on the present condition in the area. results showed an increase of 15.4, 44.5 and 230% in allocation of water to domestic, agriculture and environment sectors, respectively, in this method as...

in this paper, a combinational optimization algorithm is introduced to obtain the best size and location of static compensator (statcom) in power systems. its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. the objective of the proposed algorithm is firstly to pr...

in a region, optimal allocation of lands to various agricultural products is one of the most important issue associated with optimal use of agricultural resources. meta-goal programming is one of the multiple criteria decision models. this programming provides more flexible decisions for decision makers than other goal programming. in the current study, optimal cropping pattern was determined u...
