Robustness is the property of being strong and healthy in constitution. When it is transposed into a system, it refers to the ability of tolerating perturbations that might affect the system's functional body. In the same line robustness can be defined as "the ability of a system to resist change without adapting its initial stable configuration". [1] "Robustness in the small" refers to situations wherein perturbations are small in magnitude, which considers that the "small" magnitude hypothesis can be difficult to verify because "small" or "large" depends on the specific problem.[ citation needed ] Conversely, "Robustness in the large problem" refers to situations wherein no assumptions can be made about the magnitude of perturbations, which can either be small or large. [2] It has been discussed that robustness has two dimensions: resistance and avoidance. [3]
In commerce, supply chain management (SCM) deals with a system of procurement, operations management, logistics and marketing channels, through which raw materials can be developed into finished products and delivered to their end customers. A more narrow definition of supply chain management is the "design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronising supply with demand and measuring performance globally". This can include the movement and storage of raw materials, work-in-process inventory, finished goods, and end to end order fulfilment from the point of origin to the point of consumption. Interconnected, interrelated or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain.
Logistics is a part of supply chain management that deals with the efficient forward and reverse flow of goods, services, and related information from the point of origin to the point of consumption according to the needs of customers. Logistics management is a component that holds the supply chain together. The resources managed in logistics may include tangible goods such as materials, equipment, and supplies, as well as food and other consumable items.
A supply chain, sometimes expressed as a "supply-chain", is a complex logistics system that consists of facilities that convert raw materials into finished products and distribute them to end consumers or end customers. Meanwhile, supply chain management deals with the flow of goods within the supply chain in the most efficient manner.
Distribution is the process of making a product or service available for the consumer or business user who needs it, and a distributor is a business involved in the distribution stage of the value chain. Distribution can be done directly by the producer or service provider or by using indirect channels with distributors or intermediaries. Distribution is one of the four elements of the marketing mix: the other three elements being product, pricing, and promotion.
Vendor-managed inventory (VMI) is an inventory management practice in which a supplier of goods, usually the manufacturer, is responsible for optimizing the inventory held by a distributor.
Reverse logistics encompasses all operations related to the upstream movement of products and materials. It is "the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturing and refurbishing activities also may be included in the definition of reverse logistics." Growing green concerns and advancement of green supply chain management concepts and practices make it all the more relevant. The number of publications on the topic of reverse logistics have increased significantly over the past two decades. The first use of the term "reverse logistics" in a publication was by James R. Stock in a White Paper titled "Reverse Logistics," published by the Council of Logistics Management in 1992. The concept was further refined in subsequent publications by Stock (1998) in another Council of Logistics Management book, titled Development and Implementation of Reverse Logistics Programs, and by Rogers and Tibben-Lembke (1999) in a book published by the Reverse Logistics Association titled Going Backwards: Reverse Logistics Trends and Practices. The reverse logistics process includes the management and the sale of surplus as well as returned equipment and machines from the hardware leasing business. Normally, logistics deal with events that bring the product towards the customer. In the case of reverse logistics, the resource goes at least one step back in the supply chain. For instance, goods move from the customer to the distributor or to the manufacturer.
A supply network is a pattern of temporal and spatial processes carried out at facility nodes and over distribution links, which adds value for customers through the manufacturing and delivery of products. It comprises the general state of business affairs in which all kinds of material are transformed and moved between various value-added points to maximize the value added for customers. In the semiconductor industry, for example, work-in-process moves from fabrication to assembly, and then to the test house. The term "supply network" refers to the high-tech phenomenon of contract manufacturing where the brand owner does not touch the product. Instead, she coordinates with contract manufacturers and component suppliers who ship components to the brand owner. This business practice requires the brand owner to stay in touch with multiple parties or "network" at once.
The bullwhip effect is a supply chain phenomenon where orders to suppliers tend to have a larger variability than sales to buyers, which results in an amplified demand variability upstream. In part, this results in increasing swings in inventory in response to shifts in consumer demand as one moves further up the supply chain. The concept first appeared in Jay Forrester's Industrial Dynamics (1961) and thus it is also known as the Forrester effect. It has been described as "the observed propensity for material orders to be more variable than demand signals and for this variability to increase the further upstream a company is in a supply chain". Research at Stanford University helped incorporate the concept into supply chain vernacular using a story about Volvo. Suffering a glut in green cars, sales and marketing developed a program to sell the excess inventory. While successful in generating the desired market pull, manufacturing did not know about the promotional plans. Instead, they read the increase in sales as an indication of growing demand for green cars and ramped up production.
Supply chain security activities aim to enhance the security of the supply chain or value chain, the transport and logistics systems for the world's cargo and to "facilitate legitimate trade". Their objective is to combine traditional practices of supply-chain management with the security requirements driven by threats such as terrorism, piracy, and theft. A healthy and robust supply chain absent from security threats requires safeguarding against disturbances at all levels such as facilities, information flow, transportation of goods, and so on. A secure supply chain is critical for organizational performance.
Behavioral operations management examines and takes into consideration human behaviors and emotions when facing complex decision problems. It relates to the behavioral aspects of the use of operations research and operations management. In particular, it focuses on understanding behavior in, with and beyond models. The general purpose is to make better use and improve the use of operations theories and practice, so that the benefits received from the potential improvements to operations approaches in practice, that arise from recent findings in behavioral sciences, are realized. Behavioral operations approaches have heavily influenced supply chain management research among others.
Postponement is a business strategy employed in manufacturing and supply chain management which maximizes possible benefit and minimizes risk by delaying further investment into a product or service until the last possible moment, or where a manufacturer produces a generic product, which can be modified at a later stage before the final distribution to the customer. An example of such a strategy is Dell Computers' build-to-order online store. One of the earliest references to the concept was in a paper by Walter Zinn and Donald J. Bowersox in the Journal of Business Logistics in 1988, which highlighted five types: labelling, packaging, assembly, manufacturing and time postponements.
A supply-chain network (SCN) is an evolution of the basic supply chain. Due to rapid technological advancement, organizations with a basic supply chain can develop this chain into a more complex structure involving a higher level of interdependence and connectivity between more organizations, this constitutes a supply-chain network.
Although logistics has been mostly utilized in commercial supply chains, it is also an important tool in disaster relief operations. Humanitarian logistics is a branch of logistics which specializes in organizing the delivery and warehousing of supplies during natural disasters or complex emergencies to the affected area and people. However, this definition focuses only on the physical flow of goods to final destinations, and in reality, humanitarian logistics is far more complicated and includes forecasting and optimizing resources, managing inventory, and exchanging information. Thus, a good broader definition of humanitarian logistics is the process of planning, implementing and controlling the efficient, cost-effective flow and storage of goods and materials, as well as related information, from the point of origin to the point of consumption for the purpose of alleviating the suffering of vulnerable people.
Supply chain risk management (SCRM) is "the implementation of strategies to manage both everyday and exceptional risks along the supply chain based on continuous risk assessment with the objective of reducing vulnerability and ensuring continuity".
Merge-in-transit (MIT) is a distribution method in which several shipments from suppliers originating at different locations are consolidated into one final customer delivery. This removes the need for distribution warehouses in the supply chain, allowing customers to receive complete deliveries for their orders. Under a merge-in-transit system, merge points replace distribution warehouse. In today's global market, merge-in-transit is progressively being used in telecommunications and electronic industries. These industries are usually dynamic and flexible, in which products have been developed and changed rapidly.
Third-party logistics is an organization's long term commitment of outsourcing its distribution services to third-party logistics businesses.
Supply chain financing is a form of financial transaction wherein a third party facilitates an exchange by financing the supplier on the customer's behalf. The term also refers to the techniques and practices used by banks and other financial institutions to manage the capital invested into the supply chain and reduce risk for the parties involved.
In commerce, global supply-chain management is defined as the distribution of goods and services throughout a trans-national companies' global network to maximize profit and minimize waste. Essentially, global supply chain-management is the same as supply-chain management, but it focuses on companies and organizations that are trans-national.
Global supply-chain governance (SCG) is a term that originated around the mid-2000. It is a governing system of rules, structures and institutions that guide, control, and lead supply chains, through policies and regulations, with the goal of creating greater efficiency. Governing systems are put into place by different actors, such as international organizations and individual firms, within the global supply chain. The global supply chain is the process of transforming raw materials into an end product, which often occurs in several different countries, moving products and services from producers to consumers. Through increased globalization and international codependency, this process is expanding. This has led to the idea that there should be governing system in place to help guide these global supply chains to perform more efficiently.
Supply chain resilience is "the adaptive capability of the supply chain to prepare for unexpected events, respond to disruptions, and recover from them by maintaining continuity of operations at the desired level of connectedness and control over structure and function".
