Cost- benefit analysis is a systematic accach used in design for manufacturing to evaluate te economic compebility of different design options. It helps manufacturers choose thee mogt cost- effective solution while maintailing quality and functionality. This article provides a step-by- step exampla to ilustrate how te process works.

Step 1: Identifikace Design Alternatives

Te first step impeves listing all possible design options for a product. These alternatives bound vary in materials, manuturing processes, or appliures. For exampla, a company might consider three different materials for a consistent: plastic, aluminum, and steel.

Step 2: Odhad Costs

Next, estimate the costs associated with each alternative. Costs include material examses, manuturing labor, tooling, and any additionalouheads. For instance, plastic may have a low material cott but higher assembly time, while steel might bee more exessive but easier to produce.

Step 3: Odhadované výhody

Výhody jsou základem faktorií such a s product durability, performance, and succeomer concentration. These benefits can be quantified treamgh metrics like lifespan or contragance costs. For exampla, steel might offer longer durability, reducing substitut costs over time.

Step 4: Calculate Net Present Value

Calculate te ne present value (NPV) for each alternative by subtracting thee estimated costs from thee benefits, settled for thee time value of money. This helps comparate options over thee product 's lifecycle.

Step 5: Mace a Decision

Te final step impeves selecting the alternative with the highett NPV, indicating the mogt cost- effective choice. Consider ther factors such as risk and strategic fit before finalizing te decision.
