Clone of SIM-1: Modeling a Basic Retail Inventory System

Objective: This exercise will introduce the fundamental principles of stock and flow dynamics in a supply chain. We will learn how to model a simple inventory system using two essential tools: Microsoft Excel for discrete, day-by-day simulation, and Insight Maker for continuous, visual system dynamics modeling. 

Key Data:

·         Initial Inventory: You begin with 1,000 in stock.

·         Supply: Your supplier delivers a constant 100 per day.

·         Sales: You sell a constant 80 per day.
