Importance of logistics

A supply chain is a system of organizations, people, technology, activities, information and resources involved in moving a product or service from supplier tocustomer. Supply chain activities transform natural resources, raw materials and components into a finished product that is delivered to the end customer. In sophisticated supply chain systems, used products may re-enter the supply chain at any point where residual value is recyclable. Supply chains link value chains

In the 1980s, the term Supply Chain Management (SCM) was developed^[5] to express the need to integrate the key business processes, from end user through original suppliers. Original suppliers being those that provide products, services and information that add value for customers and other stakeholders. The basic idea behind the SCM is that companies and corporations involve themselves in a supply chain by exchanging information regarding market fluctuations and production capabilities.

The SCOR Supply-Chain Operations Reference model, developed by the Supply Chain Council, measures total supply chain performance. It is a process reference model for supply-chain management, spanning from the supplier's supplier to the customer's customer.^[3] It includes delivery and order fulfillment performance, production flexibility, warranty and returns processing costs, inventory and asset turns, and other factors in evaluating the overall effective performance of a supply chain.

The concept of Fourth-Party Logistics (4PL) provider was first defined by Andersen Consulting (Now Accenture) as an integrator that assembles the resources, capabilities and technology of its own organization and other organizations to design, build, and run comprehensive supply chain solutions. Whereas a third party logistics (3PL) service provider targets a function, a 4PL targets management of the entire process. Some have described a 4PL as a general contractor who manages other 3PLs, truckers, forwarders, custom house agents, and others, essentially taking responsibility of a complete process for the customer

Third-party logistics (3PL) involves using external organizations to execute logistics activities that have traditionally been performed within an organization itself.^[3] According to this definition, third-party logistics includes any form of outsourcing of logistics activities previously performed in-house. If, for example, a company with its own warehousing facilities decides to employ external transportation, this would be an example of third-party logistics. Logistics is an emerging business area in many countries.

Although there is some functionality overlap, the differences between warehouse management systems (WMS) and warehouse control systems (WCS) can be significant. Simply put, a WMS plans a weekly activity forecast based on such factors as statistics and trends, whereas a WCS acts like a floor supervisor, working in real time to get the job done by the most effective means. For instance, a WMS can tell the system it is going to need five of stock-keeping unit (SKU) A and five of SKU B hours in advance, but by the time it acts, other considerations may have come into play or there could be a logjam on a conveyor. A WCS can prevent that problem by working in real time and adapting to the situation by making a last-minute decision based on current activity and operational status. Working synergistically, WMS and WCS can resolve these issues and maximize efficiency for companies that rely on the effective operation of their warehouse or distribution center
