5. Break-Even Analysis
A standard approach to choosing among alternative processes or equipment
Model seeks to determine the point in units produced (and sold) where we will start making profit on the process or equipment . 14

6. Break-Even Analysis (Continued)
Break-even Demand=
Purchase cost of process or equipment
Price per unit - Cost per unit or
Total fixed costs of process or equipment
Unit price to customer - Variable costs per unit
This formula can be used to find any of its components algebraically if the other parameters are known 14

7. Break-Even Analysis (Continued)
Example: Suppose you want to purchase a new computer that will cost $5,000. It will be used to process written orders from customers who will pay $25 each for the service. The cost of labor, electricity and the form used to place the order is $5 per customer. How many customers will we need to serve to permit the total revenue to break-even with our costs?
What is Break-even Demand: 14

8. Manufacturing Process Flow Design
A process flow design can be defined as a mapping of the specific processes that raw materials, parts, and subassemblies follow as they move through a plant
The most common tools to conduct a process flow design include 15

9. Virtual Factory Defined
A virtual factory can be defined as a manufacturing operation where activities are carried out not in one central plant,

10. Capacity Capacity - number of units produced per time period
If 6 workers are employed for a process with 11 machines and each machine produces 25 parts per hour, what is the weekly capacity for a one shift operation?
