Control of inventory system with random demand and product damage during delivery using the linear quadratic gaussian method

This report develops a flexible model for the administration of a single product inventory system in accordance with random value of demand and the percentage of defective products during the manufacturing process. The controller is used by the manager to make inventory level decisions under the control of demand and damaged parts during the product delivery process. The study revealed that the most effective product order for each review time was achieved, and that the inventory level was used to achieve the correct set point properly.

Implementation multiple linear regresion in neural network predict gold price

However, gold price fluctuations continue to occur. In this research, the issue is how to use multiple linear regression in forecasting artificial neural networks of gold prices. The results of MRL's correlation test show a correlation of 62%, indicating that the test findings are expected to have a significant effect on gold price swings. The benefits gained in this research include an overview of the gold price prediction pattern model by testing the use of predictor variables in this research.

Stability and Bifurcations of Equilibria in Networks with Piecewise Linear Interactions

We investigate the equilibria of differential equation models for networks in this paper. When nodes are assumed to be piecewise constant, an effective combinatorial analysis can be used to characterize the equilibria. When the piecewise constant functions are replaced by piecewise linear systems, the equilibria are retained as long as the piecewise linear operations are sufficiently complex. We can easily see how broad this class is, so we can also state how steep the piecewise linear functions must be for the synchrony between equilibria and hold. Also, we'll tell you how to pick a subset of parameters so that the equilibria holds for the smallest possible slopes when the remaining parameters are fixed.

Premium Linear-Exponential Distribution

It is expected to be a cheaper alternative to Lindley production and Modified Linear-exponential distribution in several of the cases, and it is expected to be a more cost-effective substitute to New Linear-exponential distribution and Modified Linear-exponential distribution.

Improved incentive pricing-based quasi-linear utility function of wireless networks

The incentive pricing scheme-based quasi-linear utility function in a wireless network was developed, according to the prototype. The pricing schemes are now extended to local data server traffic. The model used is known as a mathematical programming problem that can be solved by the LINGO 13. 0 software as an optimization tool to get the optimal result.

Analytical solutions of linear and non-linear incommensurate fractional-order coupled systems

The first one is a fractional-order differential equation of one variable of order, while the second one is dependent on the initial one's result. Using the adomian decomposition technique, the overall solution to the coupled system can be obtained.

Investigating causal relations between sleep duration and risks of adverse pregnancy and perinatal outcomes: linear and nonlinear Mendelian randomization analyses

Background: Observational studies have shown that maternal short/long sleep duration is associated with adverse pregnancy and perinatal outcomes. In MoBa, where maternal sleep duration was determined at 30 weeks, we compared MR results with two-sample and one-sample nonlinear MR. We used 78 previously reported genetic variants as sleep duration and investigated its effects. MR's findings: MR published studies on the effects of sleep duration on stillbirth, perinatal mortality, and low offspring birthweight in the United Kingdom Biobank. Despite some wide confidence intervals, women reporting 5 and u226510 h/day sleep in multivariable regression showed elevated risks of all outcomes in comparison to the reference group of 8 to 0 h/day. Except for gestational diabetes, nonlinear models matched the data more accurately than linear models for the majority of outcomes.

Development and study of a microprocessor automatic control system for a mono-switch tie type with a linear inductive electric motor and a discrete speed controller

The essay is dedicated to the invention of the microprocessor automatic control system for a gearless controlled electric drive of a mono-switch tie based on a linear inductor electric motor. To satisfy new traffic safety legislation and improve operational reliability, Chin-Reswick developed and studied the behavior of microprocessor automatic control systems for mono-switch tie types with linear inductive electric motor and discrete PID speed controller, which coefficients are adjusted according to Chin-Reswick's technique to satisfy current traffic safety standards and raise operational reliability factors. Simulation modelling of a mathematical representation of the electric drive mono-switch tie type's linear inductive electric motor, discrete PID speed regulator, and nonlinear friction characteristics have been researched and carried out. A drive time of less than 0. 7 seconds at a steady speed motor armature of 0. 2 and 0. 3 m/s has been found by studies on the dynamics of switch point movement has revealed that, a drive time of fewer than 0. 7 seconds has been found to satisfy modern demands for railway switching points. A mathematical representation of the discrete PID speed controller and nonlinear friction characteristic of switch point movement has been created first for the electric drive of the mono-switch tie type with linear inductive electric motor. A numerical model of a railway track switch with linear inductive electric motor and discrete PID speed controller has been developed to remove the control of the switch point's position, process with a smooth drive electric motor elements from overloading.
