Environmentally extended input–output analysis. Environmentally extended input–output analysis (EEIOA) is used in environmental accounting as a tool which reflects production and consumption structures within one or several economies. As such, it is becoming an important addition to material flow accounting.
Material flow analysis. Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales.
Quality, cost, delivery (QCD), sometimes expanded to quality, cost, delivery, morale, safety (QCDMS), [1] is a management approach originally developed by the British automotive industry. [2] QCD assess different components of the production process and provides feedback in the form of facts and figures that help managers make logical decisions ...
A material passport allows the owner of a product/construction to know exactly what it is made of. This is of importance at the end of its useful life, to enable the most effective re-use of the materials. It allows the owner to view a product/construct as a depot, inventory of valuable materials. Furthermore, the process of creating a material ...
Material efficiency is a description or metric ( (M p) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [1] Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.
After obtaining the random sample, the following steps are carried out for the ABC analysis. Step 1: Compute the annual usage value for every item in the sample by multiplying the annual requirements by the cost per unit. Step 2: Arrange the items in descending order of the usage value calculated above. Step 3: Make a cumulative total of the ...
A multi-level bill of materials (BOM), referred to as an indented BOM, is a bill of materials that lists the assemblies, components, and parts required to make a product in a parent-child, top-down method. It provides a display of all items that are in parent-children relationships. When an item is a sub-component, of a (parent) component, it ...
Economy-wide material flow accounts ( EW-MFA) is a framework to compile statistics linking flows of materials from natural resources to a national economy. [1] EW-MFA are descriptive statistics, in physical units such as tonnes per year. EW-MFA is consistent with the principles and system boundaries of the United Nations System of National ...
