Management of Inventory for Periodically Reviewed Goods Using Discrete Higher Order Sliding Mode

Abstract: This paper describes control of inventory systems with nonperishable goods. The inventory system considered is a periodic review system where system is reviewed periodically and orders issued are replenished by the supplier after some time called lead time. The objectives expected from such a system are that the customer demand is fulfilled and the desired stock is maintained. The customer demand is considered as an uncertainty into the system and control law based on discrete sliding-mode control is developed for replenishing orders. The control law based on higher order sliding-mode control is also developed which estimates the future sales to issue the replenishment orders, thus smoothing the orders issued. The state-space model is developed and simulations are done for replenishment orders, the on-hand stock and the supply to meet the demand. The results validate the required objectives.

Comparison of wind speed, wind directions, and weibull parameters for sites having same wind power density

Abstract: Energy sustainability is one of the main issues of present world because of the fast depletion of fossil fuels such as coal, petroleum, natural gas, etc. For energy sustainability, renewable energy sources like solar, wind, and biomass are successfully being exploited. The installed capacity of wind power has already reached 32.7 GW, which is about 55% of total renewable energy power plant capacity installed in India. To establish a wind power plant, wind power density of a site is to be estimated. Wind power density is an important parameter which indicates the wind energy potential of a site before installing a wind power plant. Wind is statistically represented by Weibull parameters k (shape parameter) and c (scale parameter). In this paper, sites with same wind power density are selected and their monthly mean wind speed, monthly standard deviation of mean wind speed, and Weibull parameters are compared. The Akal (Rajasthan) site is compared with Uswad (Maharashtra) site and Bassi (Rajasthan) site. Also, Lamba (Gujarat) site is compared with Taralkatti (Karnataka). Average, quadratic average, cubic average, and median of monthly Weibull parameters are calculated and compared. For the considered sites with same wind power density, the variation in calculated statistical parameters are found to be less. Percentage variation in statistical values of monthly Weibull parameters for Bassi and Usawad (in reference to Akal site) and Taralkatti (in reference to Lamba site) are calculated. Wind pattern for all considered sites are shown by drawing wind rose diagram using excel spreadsheet.

Unified integral inequalities comprising pathway operators

Abstract: In this article, we established generalized version of unified integral inequalities, comprising pathway fractional operators related to bounded functions whose bounds are also bounded functions. We reduce these results in some useful particular forms and also some well-known inequalities of the literature.

Comparative Study of Buck-Boost, Cuk and Zeta Converter for Maximum output Power Using P&O technique with solar

Abstract: The comparison amongst the Zeta, Buck-Boost and Cuk converter having application in a solar-based system using P&O technique for tracking the maximum power point. The converter along with their pros and cons are described and simulated for their output power comparison. The simulation results conclude that among Buck-Boost, Cuk and Zeta converter. The Zeta converter works best with the solar-powered systems by tracking the maximum power without any secondary fluctuation.
