Supply chain process
This is an excerpt from the paper...
A supply chain process is made up of the flow of materials, information, and services and the monitoring and control of this flow, which includes raw materials, procurement, production, inventory management, order processing, warehousing, transportation, and distribution (Chapter 7: Simulation). The development of functions to support these operations is known as supply chain management (SCM). Systems can be developed from the top down, starting with a model at a high abstraction level and refining it by a number of steps until the desired level of detail is reached, or from the bottom up, starting with subsystems that are detailed descriptions of some aspect of the system, and composing these subsystems into a model of the entire system. Modeling and simulation is one of the key technologies of the 21st century which can be applied to a wide spectrum of disciplines, particularly for streamlining company operations of many kinds (Crosbie). Supply chain management is an important facet of the operation of modern companies and simulations of supply chain management is becoming a routine part of such operations. Modeling is used to understand systems of all kinds, and can consist of mathematical equations, rules of procedures, or graphical representations of manufacturing processes, for example (Crosbie, Chapter 7: Simulation). With a well-designed model system, it is possible to produce computer programs that can implement the model and simulate the system. Simulatio

tems to be implemented (Simulation). Programs can make simulations to give details of the effects of adding, subtracting or deleting products or entire projects and resources; for altering the priority of projects; for making changes to the timing and the resource requirements of projects; for assuming different market penetration rates for different products; and for applying different policies for assignment of resources to different projects.
Supply Chain Simulation tools were developed by the Demand Activated Manufacturing Architecture (DAMA) project to enable the U. S. ITC (which includes fiber, textile, apparel, and retail industries) to reduce the time in the supply chain, which it does by enabling the rapid exchange of information among business partners (Lovejoy and Cuirran). It includes computer-based decision support tools for cooperative business management practices with everyone in the supply chain benefitting from the decisions made. There is a tool for mid- and high-level planners which performs supply and demand analysis using supply chain information exchanged among strategic partner businesses in a customer-supplier relationship. It analyzes the trade-offs between demand forecasts, material availability, l
