This chapter explores demand forecasting in production systems. It outlines the importance of reliable forecasting for planning and decision-making, introduces types of demand profiles, and explains quantitative and qualitative forecasting methods. Core methodologies include decomposition of demand into trend, seasonality, and residual elements and exponential smoothing techniques. Evaluation metrics such as error mean and mean absolute deviation (MAD) are detailed to assess forecasting accuracy.

This document provides guidance for integrating environmental, social, and governance (ESG)-related risks into the COSO Enterprise Risk Management (ERM) framework to help organizations manage and disclose such risks effectively. It defines ESG-related risks, such as environmental and social challenges, and emphasizes the evolving global risk landscape by illustrating growing investor and stakeholder interest. The methodology highlights ERM processes from governance to performance, while explaining methods to assess, mitigate, and report risks. Organizations are encouraged to address ESG ris...

This document provides a foundational overview of machine learning, discussing concepts such as supervised, unsupervised, semi-supervised, and reinforcement learning. It describes the machine learning process from data collection and cleansing to model training and deployment. Key distinctions between machine learning and rule-based systems are highlighted, emphasizing scenarios where machine learning is preferred. Real-world cases and examples showcase the application of learning methods in different tasks with varying complexities.

This document provides an overview of multi-layer perceptrons, focusing on concepts such as forward propagation and activation functions. It explains different loss functions, including binary cross-entropy and mean squared error, along with optimization techniques such as stochastic gradient descent and momentum. Emphasis is placed on training challenges like overfitting and solutions such as dropout and early stopping. Detailed discussions on backpropagation and its role in training neural networks are also included.

This document highlights the development of a decision support system for the Arab Tunisian Bank (ATB). Agile methodologies, particularly SCRUM, were employed in conjunction with Business Intelligence tools to create an optimized DataWarehouse and Datamart for analyzing client risk and asset classifications. The solution involved designing conceptual models, exploring ROLAP, MOLAP, and HOLAP approaches, and implementing Extract-Transform-Load (ETL) processes. The outcomes included enhanced data management and reporting capabilities for better financial risk assessment and client monitoring.

This document introduces Docker Compose as a tool for defining and running multi-container Docker applications using a YAML configuration file. The example Voting App is used for demonstration, which involves multiple microservices (Voting App, Redis, Worker, PostgreSQL database, and Result App). It highlights the simplicity of deploying complex stacks with a single command and discusses how Docker Compose facilitates container networking, volume preservation, and efficient container management. Key features like environment variables, efficient container recreation, and common commands for...
