**Design**for assembly (

**DFA**) is a process by which products are designed with ease of assembly in mind. If a product contains fewer parts it will take less time to assemble, thereby reducing assembly costs. This is usually where the major cost benefits of the application of

**design**for assembly occur.

## What is DFM and DFA?

Design for Assembly (

**DFA**) techniques aim to reduce the cost and time of assembly by simplifying the product and process through such means as reducing the number of parts, combining two or more parts into one, reducing or eliminating adjustments, simplifying assembly operations, designing for parts handling and2

## What does it mean to design for cost?

**Design**-to-

**Cost**(DTC), as part of

**cost**management techniques, describes a systematic approach to controlling the

**costs**of product development and manufacturing. The basic idea is that

**costs**are designed "into the product", even from the earliest concept decisions on and are difficult to remove later.

## What is the design for the environment?

**Design for the Environment**(DfE) is a

**design**approach to reduce the overall human health and

**environmental**impact of a product, process or service, where impacts are considered across its life cycle. Different software tools have been developed to assist designers in finding optimized products or processes/services.

## What is Design for America?

**Design for America**is an idea incubator, a motivated community, and a way of approaching complicated challenges. DFA shapes the next generation of social innovators.

## What is design for disassembly?

**Design for Disassembly**is a

**design**process that allows easier access to the materials, parts and products of a builidng when it is renovated and/or

**disassembled**. It provides flexability whilst renovationg,

**disassembly**or converstion.

## What is the meaning of robust design?

**Robust**product

**design**is a concept from the teachings of Dr. Genichi Taguchi, a Japanese quality guru. It is defined as reducing variation in a product without eliminating the causes of the variation. In other words, making the product or process insensitive to variation.

## What is the Taguchi loss function?

The

**Taguchi loss function**is graphical depiction of**loss**developed by the Japanese business statistician Genichi**Taguchi**to describe a phenomenon affecting the value of products produced by a company. This means that if the product dimension goes out of the tolerance limit the quality of the product drops suddenly.8

## What is the loss function?

In mathematical optimization, statistics, econometrics, decision theory, machine learning and computational neuroscience, a

**loss function**or cost**function**is a**function**that maps an event or values of one or more variables onto a real number intuitively representing some "cost" associated with the event.9

## What is the training loss?

**Training loss**is the error on the

**training**set of data. Validation

**loss**is the error after running the validation set of data through the trained network.

**Train**/valid is the ratio between the two. Unexpectedly, as the epochs increase both validation and

**training**error drop.

## What is the cost function?

A mathematical formula used to predict the

**cost**associated with a certain action or a certain level of output. Businesses use**cost functions**to forecast the expenses associated with production, in order to determine what pricing strategies to use in order to achieve desired profit margins.11

## What is the profit function formula?

A

**profit function**is a**function**that focuses on business applications. If x represents the number of units sold, we will name these two**functions**as follows: R(x) = the revenue**function**; C(x) = the cost**function**. Therefore, our**profit function equation**will be as follows: P(x) = R(x) - C(x).12

## What do you mean by cost function?

What is a

**Cost Function**? Definition: A**cost function**is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total**cost**of production given a specific quantity produced.13

## What are the cost drivers?

A

**cost driver**is the unit of an activity that causes the change in activity's**cost**.**cost driver**is any factor which causes a change in the**cost**of an activity. — Chartered Institute of Management Accountants.14

## What is the cost equation?

A

**cost equation**is a mathematical**formula**that a company can use to predict the expenses associated with the production and sale of a certain amount of goods. The**formula**typically incorporates constant overhead**costs**as well as variable**costs**that depend on the volume of sales.15

## What is the cost formula?

Total

**cost formula**. July 31, 2017. The total**cost formula**is used to derive the combined variable and fixed**costs**of a batch of goods or services. The**formula**is the average fixed**cost**per unit plus the average variable**cost**per unit, multiplied by the number of units.16

## What is the formula for revenue?

Sales

**revenue**is one of the key indicators of the well-being of a company. Sales**revenue**is generated by multiplying the number of a product sold by the sales amount using the formula: Sales**Revenue**= Units Sold x Sales Price. The more sales a company makes, the more money available within the business.
