This paper proposes a hybrid policy for a stochastic inventory system facing regular demand and surge demand. The combination of two different demand patterns can be observed in many areas, such as healthcare inventory and humanitarian supply chain management. The surge demand has a lower arrival rate but higher demand volume per arrival. The solution approach proposed in this paper incorporate...

in this present study the dissolved air flotation (daf) system was investigated for the treatment of kermanshah oil refinery wastewater. the effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (cod) removal was examined experimentally. all the experiments were done under a...

Introduction The ability to forecast the onset, duration and severity of droughts, floods, and disease outbreaks with reasonable accuracy, especially in terms of their prospective human welfare effects, is critical to the design of timely and cost-effective early warnings and emergency response systems that can minimize the suffering of populations adversely affected by such relatively slow-ons...

This research presents a decentralised incentive-based demand response (DR) program using blockchain technology. Consumers self-report baseline to the system operator (SO), smart contract confirms validity of data execute transactions and finally validators record information on network. During DR event, set consumers are randomly selected deliver required load reduction. The signalled consumer...

in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...
