Smooth implementation and controlling conflicting goals of a project with the usage of all related resources through organization is inherently a complex task to management. At the same time deterministic models are never efficient in practical project management (PM) decision problems because the related parameters are frequently fuzzy in nature. The project execution time is a major concern o...

risk management is one of the nine project management processes, which provides positive results and minimizes the probability and consequences of adverse effects in the project.  in this article a zero-one linear programming model with multiple objectives is used to characterize the potential risks. the proposed model has two main objectives. the first objective is the minimization of the expe...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

with the implementation of the affordable care act (aca), access to insurance and coverage of preventive care services has been expanded. by removing the barrier of shared costs for preventive care, it is expected that an increase in utilization of preventive care services will reduce the cost of chronic diseases. early detection and treatment is anticipated to be less costly than treatment at ...

faults in computer networks may result in millions of dollars in cost. faults in a network need to be localized and repaired to keep the health of the network. fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. in this paper, we propose a novel approach based on imperialist competitive alg...

introduction: allocation of the new (expensive) drugs for difficult refractory diseases and financial protection of the patients is an important challenge in the national health systems worldwide especially in developing countries.â  trastuzumab (herceptin) as one of the effective but expensive drugs, put major financial burden for the iranian patients and government. so the ministry of health ...
