Supply Chain Management: Push and Pull Based Chains

The main elements of a supply chain include purchasing, operations, distribution, and integration. The supply chain begins with purchasing. Purchasing managers or buyers are typically responsible for determining which products their company will sell, sourcing product suppliers and vendors, and procuring products from vendors at prices and terms that meets profitability goals.

The timing of capacity changes also needs to be taken into consideration to achieve maximum efficenty given that demands of their products varies with seasonal changes. The ability to react to market demand changes quickly will determine manufacturers flexibility in keeping up with these demands. Manufacturers needs facilities to produce, whether warehouses to store its raw materials or finished goods, or manufacturing plants to produce their products. Services facilities are needed by certain manufacturing industries such as consumer electronics to cater for returns. Distribution centres also determine the efficenty of production distribution and un-nesessary inventory holding will result in higher holding cost. Such facilities require large investments and are integral of the manufacturer’s supply chain strategy and thus proper planning is needed when making these decisions regardong the size, location which affect the overall operations. How manufacturers run their productions also determine how successful will they be in terms of productivity and quality levels. Different types of equipment and processes also affect the cost and output of the manufacturing plant. Information systems that flow both upstream and downstream affects the forecasting, planning, inventory and production levels, they must be robust to ensure the manufacturing firm is able to react accordingly to changing demands and variations. In addition to their internal environment,

Supply chains must be managed to coordinate the inputs with the outputs in a firm to achieve the appropriate competitive priorities of the firm’s enterprise processes. The Internet offers firms an alternative to traditional methods for managing supply chains. A supply chain strategy is essential

Supply chains manage the movement of products from the acquisition of raw materials through production and finally distribution to the end user. A properly designed supply chain can create many opportunities to drive down cost and increase revenue opportunities. In order to create a supply chain that is sustainable and flexible it is necessary to identify and align company goals and initiatives with the manufacturing and distribution of products.

We prefer the EOQ/ ROP system as gains from reducing the order/ production size (gains in terms of less value of inventory being produced) which though lead to increase in setup cost far outweigh the gains from Blanchard’s current system (gains in terms of reduction of setup cost) while, costs are that of the value of inventory being produced.

Since Wal-Mart is a mass market retailer, its primary source of value that it adds to the company is derived from its supply chain. Wal-Mart has suppliers located all over the world and it purchases goods from a wide range of different types of vendors. Many of the company's primary vendors are directly connected to Wal-Mart's IT systems through what is referred to as an electronic data interchange (EDI). An EDI can instantaneous transmit data between Wal-Mart and their vendors. Such information can consist of order information, stock supplies, demand forecasting and many other key supply chain metrics. The advantages of such a system are clear as they can greatly assist creating efficiencies in the supply chain. However, not all suppliers have developed sufficient IT technologies to participate in an EDI program with Wal-Mart. Another option for greater coordination between parties in the supply chain is web-based supplier integration. Although the web-based systems are not quite as sophisticated as an EDI, they are more accessible for many of the smaller suppliers and they have shown to improve long-term coordination, cooperation, and commitment.

Integrated operations are controlled through collaborative planning, forecasting and replenishment through the use of effective is done through pathways such as resource optimization. This is a function of mathematical programming to determine how to most effectively meet the demands of the consumers while optimizing the resources and resource utilization. The results are multiple supply chains forecasted in to future time periods which then helps in determining which products should be produced, when they should be produced, and also helps in determining the most effective way in storing the materials across the supply chain.

Effective supply chain management can provide an important competitive advantage for a business marketer, resulting in improved communication and involvement among members of the chain, increased motivation, and decreased costs. Tracking the movement of and demand for components used to manufacture a product across a variety of potential and actual suppliers, provides insight and the ability to respond instantly to shortages, surpluses, and changes in market conditions. It seeks to optimize production, decrease manufacturing time, minimize inventory, streamline order fulfillment, and reduce cost.

Many companies produce products from parts of raw materials that are purchased from suppliers, till these products are reach the markets and presented for the customers, then you have the supply chain starting from the purchase of raw material from different areas , through the manufacturing steps and stages till is being sold by the consumer. Some of supply chains are well defined and easy to determined, while there are other supply chains complex to analyze. However, supply chains vary with the size of the facility such as; complexities, performance, abilities, flexibility, quality, speed, dependability and cost of preparing goods for manufacturing and the chain length distribution. So the supply chain is a network of wholesalers, retailers, distributors, workers in the transport, storage facilities, suppliers, and manufacturers who participate in the production, delivery and sale of the product to the last consumer. A supply chain is a group of facilities that coordinate activities among it and to avoid the competitors. Moreover, to ensure the supply chain management is operating efficiently and generating the highest level of customer

The supply chain is a system made amongst different companies producing and distributing the product. Specifically, the supply chain contains the steps it takes to deliver goods or services from the supplier to the customer.

Supply chains represent the procurement, production and distribution activities of an organisation. Within a supply chain, these activities are viewed as linked and reliant on one another to produce the final outcome. It is believed that if one component of the chain fails, the whole chain is broken and product/service delivery goals will not be achieved.

These influences the way companies plan their inventory, evolving to Collaborative Planning, Forecasting and Replenishment (CPFR).

Supply chain: Supply chain encompasses all activities associated with the flow and transformation of goods from the raw materials stage (extraction) through to the end user all well as the associated information flows. Material and

“The management of a network of relationships within a firm and between interdependent organizations and business units consisting of material suppliers, purchasing, production facilities, logistics, marketing, and related systems that facilitate the forward and reverse flow of materials, services, finances and information from the original producer to final customer with the benefits of adding value, maximizing profitability through efficiencies, and achieving customer satisfaction.”

A supply chain is a system of organizations, people, technology, activities, information and resources involved in moving a product or service from supplier to customer. Supply chain activities transform natural resources, 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.
