Question 2: (25 marks) A Decision Support System (DSS) is a computerized system used for assisting the process of decision making. The essence of a DSS is its ability to integrate a variety of data sources and systems such as spreadsheets, relational databases, expert systems, and artificial intelligence (AI) to provide comprehensive support to decision-makers. You are required to design a conceptual model for a Decision Support System (DSS) for a mid-sized retail company that wants to improve its inventory management and customer satisfaction. Your design should include the following components: (5 marks) Spread sheet module: Design a spreadsheet model that the company can use to track inventory levels, sales patterns, and restocking needs. Describe how this spreadsheet will be used for predictive analysis based on historical data. (5 marks) Relational database module: Outline a relational database schema that can store customer information, transaction history, and product details. Explain how the relational database will interact with the spreadsheet module and how it will support the DSS in terms of data storage and retrieval. (5 marks) Expert system module: Propose an expert system that could help in automating some decision-making processes like identifying products for promotional offers or bundling based on buying patterns. Explain the four components of expert system and how each component will contribute to the process of decision making. (5 marks) AI module Suggest how AI could be incorporated into the DSS for advanced analytics such as demand forecasting and customer segmentation. Describe what machine learning models could be useful and how they would process data from both the spreadsheet and the database. (5 marks) Explain how each component of the DSS and how they integrate to support decision- making in the retail context. You can also draw a diagram illustrating the flow of data between the spreadsheet, database, expert system, and AI components. A reflection on how each component contributes to the overall effectiveness of the DSS and the potential benefits it could bring to the retail company.
