+# Cost Modelling
+
+Key issues in selection:
+
+- Component function, including materials and shape, form, and assembly
+- Manufacturing process may greatly affect material properties, such as yield strength
+- Similarly, the material will likely decide the manufacturing process
+- Cost of a material and manufacture
+
+The main requirement for a product to be viable is 
+
+$$cost < price < value$$
+
+Cost modelling equation:
+
+$$C = \frac{mC_m}{1-f} + \frac{C_t}{n} + \frac{1}{\dot n} \left[ \dot C_{oh} + \frac{C_c}{L\cdot t_{wo}} \right]$$
