How do you use Arena's data modules and analysis tools to check and improve input data quality?

1 Data modules overview

Arena provides several data modules that help you define, store, and manipulate input data for your simulation models. These include Input Analyzer, Process Analyzer, Output Analyzer, and Data Analyzer. Each module has its own purpose and functionality, but they can also work together to create a comprehensive data analysis workflow. Let's briefly review what each module can do for you.

2 Input Analyzer

Input Analyzer is a tool that helps you fit probability distributions to your input data. You can use it to import data from external sources, such as Excel or text files, or generate data from scratch. Input Analyzer can also perform goodness-of-fit tests, compare different distributions, and export the fitted expressions to Arena or other applications. You can use Input Analyzer to validate your input data by checking if it follows a reasonable and realistic distribution.

3 Process Analyzer

Process Analyzer is a tool that helps you design and compare alternative scenarios for your simulation models. You can use it to create scenarios with different input parameters, run multiple replications, and generate summary reports and graphs. Process Analyzer can also perform statistical tests, such as confidence intervals and hypothesis tests, to compare the performance of different scenarios. You can use Process Analyzer to verify your input data by checking if it produces consistent and significant results.

4 Output Analyzer

Output Analyzer is a tool that helps you analyze the output data from your simulation models. You can use it to import data from Arena or other sources, such as Excel or text files, and perform various statistical analyses, such as descriptive statistics, frequency analysis, correlation analysis, and regression analysis. Output Analyzer can also generate charts and tables to visualize and summarize your output data. You can use Output Analyzer to validate your output data by checking if it matches your expectations and assumptions.

5 Data Analyzer

Data Analyzer is a tool that helps you manipulate and transform your input and output data. You can use it to perform operations such as sorting, filtering, grouping, aggregating, and calculating new variables. Data Analyzer can also create pivot tables and charts to display and explore your data. You can use Data Analyzer to verify your input and output data by checking if it contains any errors or outliers.
