What are the factors that should be considered in a supply chain?
There are at least nine crucial factors to consider. 1. Determine Goals and Objectives and Create Buy-In. It's essential to have a clear idea of what the organization hopes to achieve as well as an honest assessment of the time, effort and cost. Supply chain network design is not an exercise that can be conducted in isolation;
What is supply chain network design?
Supply chain network design is an excellent technique for optimizing and managing an organization's supply chain. The modeling approach allows the analysis of different scenarios as well as helping determine the best supply chain decisions. While SCND is relatively costly, the benefits far outweigh the initial expense. Mathematical coding models are powerful, but they depend on high-level OR skills while drag-and-drop modeling offers greater visibility that's more easily internalized. OR and IT support is essential, as is the involvement of line managers and personnel involved in supply chain decisions.
Why should SCND be tackled in a professional and organized manner?
Because it analyzes and impacts the organization's entire supply chain, from start to finish, SCND should be tackled in a professional and organized manner. Many factors need to be considered, such as goals, objectives, costs, buy-in and the best way to model the organization to closely reflect actual performance.
What is the third task after defining and modeling the supply chain?
The third major task after defining and modeling the supply chain is data preparation. In most organizations, there's a wealth of data. However, additional sources of data may need to be identified and acquired, especially relating to forecasts and future market trends.
What is the first task in supply chain analysis?
The first task is to define the existing supply chain network in some detail. This is an important, if relatively time-consuming, process. The level of detail required varies depending upon the type of analysis, but it's better to work with the greatest level of detail possible, as this means there are fewer errors.
What is modeling platform?
Modeling platforms are powerful and flexible but generally require advanced coding skills. Some use drag-and-drop modeling, which is easier to configure and simplifies mathematical modeling. 4. Formally Defining the Existing Supply Chain Network.
How does a supply chain develop?
A supply chain naturally develops in an ad hoc fashion as new products are introduced or when changes are made to existing products. While supply chain managers are aware of this and endeavor to consolidate sourcing, a degree of complexity and fragmentation is almost always inevitable.
What is network ready operating system?

Is Wi-Fi network secure?
While it is possible to eliminate the expense of Ethernet cabling by opting for a wireless network solution, Wi-Fi networking is the least secure method of sharing data and connections. The encryption methods built into most commercial routers, Wireless Encryption Protocol (WEP), Wireless Protected Access (WPA) and the more recent WPA2, can be cracked by skilled hackers. Designing a network with hard-wired Ethernet connections eliminates the risk of intrusion to only those with physical access to the network. Unfortunately, this risk expands dramatically when the local network is connected to the Internet.
How to achieve network design?
To achieve a network design that delivers value to the business and aligns with its goals and directions, network designers must follow a structured approach. This approach must start from the top level, focusing on business needs, drivers, and directions, to generate a business-driven design. In addition, with the top-down approach, network designers and architects can always produce business-driven network architecture that facilitates, at later stages, the selection of the desired hardware platforms and technol-ogy features and protocols to deploy the intended design. This makes the network design more responsive to any new business or technology requirements. Furthermore, considering the different design principles discussed in this chapter and considering the different requirements (business, functional, and mission-critical applications) can help network designers to plan and make the right design choices that ultimately will make the network be seen as a “business enabler.”
How to develop a successful network design?
To develop a successful network design, a proper planning approach is required to build a coherent strategy for the overall design. Network designers can follow two common planning approaches to develop business-driven network designs and facilitate the design decisions:
What is scalable network design?
In fact, what can be considered as a successful scalable network is not only measured by the network size factor but also by how stable and reliable the net-work is and how easily this network can be managed and troubleshot. For example, a network may be designed in a way that can expand to thousands of routers, but at the same time, a failure in one link or device can introduce a high degree of processing and CPU utilization across the network, which may lead to instability. This design cannot be considered a successful scalable design, even though it can grow to a large number of routers. Similarly, a network may be designed to grow to a large scale while at the same time being difficult to manage and troubleshoot, with any issue potentially taking a long time to be fixed. This network cannot be considered a successful scalable design either.
What is network design?
Network design can be defined as the philosophy that drives how various components, protocols, and technologies should be integrated and deployed based on certain approach-es and principles to construct a cohesive network infrastructure environment that can facili-tate the achievement of tactical or strategic business goals. Previous sections in this chapter described the end-to-end process of a network design (PPDIOO) and the approaches that you can use to tackle different network designs (top down and bottom up).
What are constraints in network design?
Constraints are factors or decisions already in place and cannot be changed and often lead to a direct or indirect impact on the overall design and its functional requirements. In reality, various design constraints affect network design. The following are the most common constraints that network designers must consider:
What are functional requirements?
Specifically, functional requirements identify what these technologies or systems will deliver to the business from a technological point of view. For example, a Multiprotocol Label Switching (MPLS)-enabled service provider might explicitly specify a functional requirement in a statement like this: “The provider edge routers must send VoIP traffic over 10G fiber link while data traffic is to be sent over the OC-48 link.” It is implied that this service provider network needs to have provider edge (PE) routers that support a mechanism capable of sending different types of traffic over different paths, such as MPLS Traffic Engineering (MPLS-TE). Therefore, the functional requirements are sometimes referred to as behavioral requirements because they address what a system does.
What is the importance of classifying the industry?
Classifying the industry in which the business belongs or identifying the business’s origins can aid in the understanding of some indirect requirements, even if these are not mentioned explicitly. For example, information security is almost always a must for a banking business whenever traffic crosses any external link. So by default, when planning a design for a business based in the banking industry, the design must sup-port or offer security capabilities to gain acceptance from the business. In addition, industry-specific standards apply to IT infrastructure and services need to be considered. (For instance, healthcare organizations may consider complying with the IEC-80001-1 standard. 2 )
