Reverse Logistics Network Modelling
Reverse logistics is for all operations related to the reuse of products and materials. It is "the process of moving good (economics), goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturing and Refurbishment (electronics), refurbishing activities also may be included in the definition of reverse logistics."Hawks, Karen"What is Reverse Logistics?" ''Reverse Logistics Magazine'', Winter/Spring 2006. In order to model reverse logistics network from an economics point of view, the following simplified reverse logistics system has to be set. In this model, the products are gathered from the consumers and transferred back to the producers, hence the direction of the flow in the distribution supply chain is reversed and the model is expanded with the recovery centre. First of all, the used products are collected from the consumers and moved to the recovery centre, where the condition of the products are examined according to t ...

Good (economics)
In economics, goods are anything that is good, usually in the sense that it provides well-being, welfare or utility to someone.Alan V. Deardorff, 2006. ''Terms Of Trade: Glossary of International Economics'', World Scientific. Online version: Deardorffs' Glossary of International Economics"good" an Goods can be contrasted with bads, i.e. things that provide negative value for users, like chore division, chores or waste. A bad lowers a consumer's overall welfare. Economics focuses on the study of economic goods, i.e. goods that are scarce; in other words, producing the good requires expending effort or resources. Economic goods contrast with free goods such as air, for which there is an unlimited supply.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. Goods are the result of the Secondary sector of the economy which involves the transformation of raw materials or intermediate goods into goods. Utility and characteristics of goods The c ...

Remanufacturing
Remanufacturing is "the rebuilding of a product to specifications of the original manufactured product using a combination of reused, repaired and new parts". It requires the repair or replacement of worn out or obsolete components and modules. Parts subject to degradation affecting the performance or the expected life of the whole are replaced. Remanufacturing is a form of a product recovery process that differs from other recovery processes in its completeness: a remanufactured machine should match the same customer expectation as new machines. In 1995, the United States Environmental Protection Agency (EPA) implemented the Comprehensive Procurement Guideline (CPG) program to promote waste reduction and resource conservation through the use of materials recovered from solid waste, and to ensure that the materials collected in recycling programs will be used again in the manufacture of new products. The EPA is required to designate products that are or can be made with recovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refurbishment (electronics)
In electronics, refurbishment is the practice of restoring and testing a Used good, pre-owned electronic device so that it can be re-sold. Refurbished electronics are therefore pre-owned electronic devices (usually smartphones, Tablet computer, tablets, or laptops), that have been tested by a reseller to confirm that they are fully working. Other refurbished electronics include smartwatches, Video game console, games consoles, and cameras. Usually, a refurbished electronic device is one that has been previously returned or re-sold to a retailer for any reason. They are then tested, and if necessary, repaired by a specialist refurbisher (or sometimes by the original manufacturer). Refurbished electronics may also be referred to as renewed, reconditioned, recycled, recertified, or "like new" electronics. Competing definitions In many countries, the word "refurbished" is not legally protected (although France has introduced a legal definition as of 2022). This means that differen ...

Binary Data
Binary data is data whose unit can take on only two possible states. These are often labelled as 0 and 1 in accordance with the binary numeral system and Boolean algebra. Binary data occurs in many different technical and scientific fields, where it can be called by different names including '' bit'' (binary digit) in computer science, '' truth value'' in mathematical logic and related domains and '' binary variable'' in statistics. Mathematical and combinatoric foundations A discrete variable that can take only one state contains zero information, and is the next natural number after 1. That is why the bit, a variable with only two possible values, is a standard primary unit of information. A collection of bits may have states: see binary number for details. Number of states of a collection of discrete variables depends exponentially on the number of variables, and only as a power law on number of states of each variable. Ten bits have more () states than three dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
