This study presents the elements and methodology of the reinforcement learning model according to the agent-based conceptual model of hospital accreditation in Iran. The elements and methodology of the mentioned model will create a favorable study base for creating a smart and multi-agent hospital accreditation system and environment simulation trends to provide efficient guidelines to relevant agents and policymakers. Also, this study intends to provide an appropriate answer to the main research questions in which there are uncertainties related to the reinforcement learning elements and how to choose the reinforcement learning methodology in a multi-agent system of the socio-technical systems type.

To collect the information needed to know the elements and identify the hospital accreditation processes, agents, environment, and interaction between them, the systematic review of sources, review of scientific documents, and semi-structured interviews, through experts, to The face-to-face method has been used. Summarizing the interviews was done using grounded-theory-based methods, and a sequential and systematic approach. The sources for collecting the characteristics of the machine learning process using the systematic review method were from the document "Iran Hospital Accreditation Guide 2022". Also, the process of selecting the mentioned features was done through the correct selection of the output features of the model, which are the actions of the agent. The list of agent actions was extracted from the conceptual content of the document above in the form of a general non-binary tree based on the classification of the tree structure.

The extracted reinforcement learning model will seek to find the optimal chains of operational actions, in the conditions where the quantitative data of the hospital is available. The most important elements of the mentioned model are:Set of states: set of hospital accreditation factors such as input variables, output variables, indicators, parameters, and fixed numbers related to the metrics of each conceptual agent in the document "Iran Hospital Accreditation Guide 2022".Set of actions: actions of intelligent agents in each reinforcement learning episode, paths from the hierarchically clustered binary tree are operational actions that can be performed in the hospital and per set of state features.Reward function: "Obtaining the highest possible score in the hospital ranking system by performing the least number of necessary actions and actions."Policy function: Based on the learning process of each agent, it is based on a DQN deep neural network and gradient reduction algorithm.Operational Agents: the operational goal of each of the conceptual agents, is "maximizing the accreditation points of the metrics of the relevant field by recommending the least measures."The general cycle of the model: in this structure, each of the intelligent agents, a subset of the 9 conceptual agents, has a multi-layered neural network within its scope, and the characteristics of related states are entered into this neural network and Output, based on the definition of the special policy function of that agent, a map of optimal actions will be created according to the agent's current conditions and states.Neural network model: The neural network of the intelligent agent is derived from the conceptual agent "management and leadership" in which the input, hidden, and output layers of the network are specified.

Summarizing the background of related research showed that the approach to designing hospital accreditation models can be divided into two groups: "conceptual models without using intelligent agents" and "conceptual models using Intelligence and operating systems" should be divided. The investigations showed that these studies had the expected results and that the efficiency and effectiveness of the models and processes proposed by them had the necessary validity.

The aims of this study is to provide a conceptual model of hospital accreditation in Iran through qualitative research. The grounded theory model was compiled using the results of the analysis of the interviews. Then, with the help of the grounded theory model and the results of qualitative analysis, a state diagram was obtained. Using the state diagram, initial sampling, systematic review of sources and results of interviews, 9 conceptual agents "governance organizations, management and leadership, clinical personnel, support personnel, hospital infrastructure, assessor, standards, assessment method and service recipient" were identified. Finally, the conceptual model of agent-based, environment, behavioral rules of agents and their input and output interactions was presented. In future researches, reinforcement learning models can be designed according to the conceptual model of this study, so that by using it, software developers can develop a suitable framework for solving complex problems in the field of hospital accreditation. Because the field of hospital management systems is one of the desirable types of socio-technical systems that have high capacities.

Index of usability evaluates performance, user satisfaction and increased productivity in a product. Principles of usability are effectiveness, efficiency, safety, utility, learnability, Memorability. This Study Aims to Develop a Tool to Estimate and Evaluate the Usability of Web Applications in the field of Automation Research has been determined. After extracting, an initial questionnaire to assess the usability of the standard resource for indices of validity, internal consistency and reproducibility, respectively technique for determining the content validity, test-retest method and cronbach's alpha coefficient were used. The most important steps were as follow: (1) determine the scope and dimensions of the questions (2) preparing draft questionnaire (3) appoint the members of the expert panel (4) methods, how data analysis (5) determine the acceptance criteria of the questions (6) determine the content validity index (7) determine reliability of the questionnaire (8) determine reproducibility of the questionnaire. A 50-Item questionnaire was designed as the ultimate tool. The content validity index value of 0.763 was obtained ultimately for the questionnaire. Analysis of the questionnaire responses revealed that the lower backend errors related to the reliability coefficient alpha value was equal to 0.742. Finally, the degree of reproducibility of the questionnaire, using test-retest method, was equal to value of 0.993 (p <0.001). After the final questionnaire design, with good reliability and validity, it is noticeable that the designed tool is applicable on relevant softwares and may improve the quality and efficiency of the software and user interface.
