In this paper, based on Effective Open-loop Process (EOP), an iterative procedure is proposed to tune decentralized PID controllers for multivariable systems. the EOP is obtained through the operation with matrices, regardless of the process order. From the definition of the constraints, it is possible to guarantee minimum bounds of gain and phase margins. the optimization problem subject to these constraints imposes stability restrictions under the actual EOP loop-gain transfer function between the process input and output. the iterative procedure solves only one optimization problem for each controller. Besides, the optimization problem is applied to all loops, and its solution is obtained by linear programming. Simulation studies illustrate the results.

An energy management algorithm to optimally control a rooftop solar photovoltaic device in combination with a battery storage and considering variable pricing is analyzed for single family houses. A discrete time dynamic programming controller is developed to minimize the electricity costs. It is shown in simulation, using real world measurement data, that considerable savings can be achieved withthe optimal controller. However, we also show the limitations of such discrete time approaches in realistic scenarios when load and generation changes in-between the samples where the controller is active. this can lead to a performance deterioration making the optimal controller worse than a standard approach.

this study aims to use alternative data on measuring bank branch performance within the NCR in the Philippines. It is also aimed to identify optimal solution in maximizing the bank branches performance as a community while minimizing the operating expense using goal programming approach. It was concluded that bank branch performance in NCR is largely dependent on the number of accounts and number of over-the-counter transactions. the result of this study is very timely as the banks in the country have already started charging its clients for over-the-counter transactions, such as withdrawals and inter-regional deposits. Since the number of over-the-counter transactions has a positive effect on branch performance, the management should think of ways on how it can entice its clients on transacting in the branch instead of using the digital platforms.

the traditional PID control algorithm requires tuning and optimization to achieve better control performance in the nonlinear time-delay system, which complicates the controller design. We proposed a new self-tuning and optimization algorithm for controller parameters based on Adaptive Dynamic programming(ADP). the algorithm uses neural networks to approximate the performance index functions and control strategies in dynamic programming to achieve online self-tuning and optimization of control parameters. Using ADP and Genetic algorithms tuning Proportional-Integral-Derivative(PID) control parameters and comparing the results can demonstrate the feasibility and effectiveness of our proposed approach.

this paper presents a new mathematic model proposed to optimized appointment scheduling problems in healthcare. We actually introduced an Integer programming model with a Tabu search approach while add a simulation model addressed in Appointment Scheduling (AS) healthcare operating system for the assessment in an emergency center of various patient flow control and timing scenarios to obtain minimum patient waiting time and patient satisfaction during their treatment in hospital.

Based on research findings, a significant obstacle for students in learning mathematics is their difficulty understanding word problems. Converting verbal explanations into mathematical equations becomes difficult, especially when several procedures are necessary. thus, this study developed a supplemental tool for grade 7 students that is designed to assist them in effectively converting English language phrases into mathematical expressions, thereby enhancing their learning experience. this study encompasses both a web application and a translation algorithm. the web application is an educational tool that delivers content that teaches the mathematical concept of “Translating English Phrases and Sentences into Mathematical Equations and Statements”. Meanwhile, the translation algorithm, developed using Stanza, a Python Natural Language Processing (NLP) package, is tasked with transforming given English mathematical phrases into their corresponding mathematical expressions. the system was created using the Rapid Application Development (RAD) software development model to implement progressive improvements within three development iterations, and it was then assessed for functional suitability, usability, and reliability using the ISO/IEC-25010 System and software quality model. the outcomes of the survey evaluation revealed that the system proved to be fitting for learning math phrase translations. It proved dependability, convenience, and usability. Furthermore, the algorithm’s precision was evaluated, with 175 predictions yielding an accuracy rate of 81.14%. In summary, this study introduces a valuable resource for math educators and learners, enhancing their comprehension of math phrase translations.
