The impact of inventory stored at different stages of the supply chain is significant. Determining the minimum and maximum levels of inventory and the amount of order to be placed are major challenges for decision makers. An (s, S) ordering policy specifies these decision variables by placing an order when the level of inventory is below s units, and by specifying the amount of the order by the difference between maximum inventory level (S) and the current inventory position. Provided that determining optimal values of (s, S) is computationally expensive, simulation-based optimisation is a potential tool for analysing alternatives and finding these optimal values. Infinitesimal perturbation analysis (IPA) is used by (Gavirneni, 2001) in a capacitated supply chain. Besides computing the appropriate order up-to level, they also measured the benefit of sharing the inventory parameters of the retailer’s ordering policy and demand data with the supplier which reduced the supplier’s cost by 1%–35%. Simulated annealing and ranking & selection procedure can be combined to find optimal value...
On the same note, it is well acknowledged that the competitiveness of any organization fundamentally depends on the workforce. Indeed, the workforce is recognized as the heart or living organism of any organization including hotels. It goes without saying that there is minimum likelihood that a restaurant where workers operate in unsafe conditions or are mistreated will offer services and products of the highest quality. Scholars note that employees always desire to work in institutions or restaurants that have high standards of integrity and strive to do the appropriate thing (Fox & Vorley, 2004 pp. 33). This is especially so for the new generation workforce, as well as in attracting the best talent in the industry. A reputation for responsibility and integrity has been recognized as crucial in motivating, as well as recruiting staff especially considering that individuals care about the principles and values that their employers wish to uphold. Scholars note that operating voluntarily to high ethical standards pertaining to environment and social responsibility can result in competitive advantage (Schlegelmilch et al, 2004, pp. pp 254). Customers and civil society groups have been increasingly vigilant in determining whether there is an ethical lapse in the manner in which employees are treated within the supply chain of any organization (Fox & Vorley, 2004 pp. 33). In fact, they have been pressurizing restaurants and other business entities to cut ties with any organization in their supply chain that is not ethical in its treatment of employees. Scholars note that the impression that a restaurant or business entity would create in terms of public relations both on the stakeholders and the customers is highly dependent on the ac...
Inventory management has traditionally been considered as a necessary resource that every company needed. Its primary purpose was to evaluate and control inventory from the raw material level, through the production process and control stage, to the final out-door delivery. These older models of inventory management had several issues, such as inefficient control system, long cycle time, and bureaucratic process. Beginning in the late 1980s, many corporate businesses became deeply interested in developing new inventory management system that will reduce operation cost and expand market chare. Today, the business world is still improving its inventory system. The most effective systems are now not just count products and manage production schedule, but obtain lower prices by making large purchases, and increase inventory turnover. Today, forward-looking corporations build their serious efforts at inventory management systems through implementing new technologies, involved digitization, Internet, high-speed data network, and other e-sources that became available after business outsourcing and globalization.

Prior to the start of the Littlefield simulation we developed a strategy based off the first 50 days of data. We made projections of the following elements of data to primarily set up our monitoring framework and to make our decisions – job arrivals rate, inventory levels (reorder point and reorder quantity with supplier’s lead time), overall lead time and machine utilization. In addition we included the interest rate earned on cash as an additional criterion and adopted an opportunistic contract switching approach into our decision framework to maximize the revenue.
This software can be used to optimize the supply chain cycles and warehouse management according to the company’s unique needs. The software packages contains stuff to better handle the supply chain management, purchasing, requisitioning and procurement, inventory management, and order entry and processing management. This software package allows Dirt Bike the ability to integrate all of their sales and purchasing systems to make the process go faster.
Organizations that supply goods and services to consumers all have one thing in common; inventory on hand and a management system to control the flow of goods. Heizer and Render (2014) stated that organizations must determine whether to produce goods or to purchase them and once the decision is made, the organization must then forecast the demand for these products. This function is especially critical in the automobile, hospitality (food & beverage, lodging) and retail industries. Supply and demand are the key components in determining what type of inventory and how much to carry on-hand, but the most expensive part of inventory is the carrying cost, also known as the cost of storing the inventory (Young,
Launched by Jeff Bezos, the Amazon.com website started in 1995 and is today considered as one of the most prominent retail website on the internet with a record turnover of US$ 14.87 billion in 2007. Jeff Bezos’s intention was to create an internet based company with the most dedicated product portfolio on the internet where customers could find anything they might want. Amazon’s success is based on technology, services and products (Jens et al., 2003).
Another method is forecast demand, which is based on service level via profit margin calculations. Bean will have to consider the contribution margin in case an item is bought vs. the liquidation costs spent if the item is not demanded. To calculate the item’s probability distribution of demand is a critical ratio of under stocking costs that is relative to the sum of under stocking and overstocking costs. This calculation determines at what point it is optimal to hold the stock in order to balance overstocking and under stocking costs. Critical ratio is combined with the corresponding forecast error and the number of items to stock is the product of these two numbers and the frozen
This report has clearly in detail described the meaning, benefits as well as the need and challenges of the RFID in the supply chain system. While RFID comes with a larger magnitude of benefits than the bar code, it’s an expensive medium and comes at a price that may be prohibitive to many businesses. On the one hand, RFID is advantageous in different areas of the supply chain and does not require line-of-sight scanning; it helps in labor reduction, enhances visibility of products and processes , and helps in inventory management. On the other hand, RFID is an expensive solution, lacking benchmarks or standards, suffers from some adverse deployment issues, and suffers from major privacy concerns. However with the ultimate aim to see the establishment of item-level tracking which should act to revolutionize SCM practices, RFID is here to stay.

Inventory management is a method through which a business handles tangible resources and materials to ensure availability of resources for use. It is a collection of interdisciplinary processes including a full circle of the demand forecasting, supply chain management, inventory control and reverse logistics. Inventory management is the optimization of inventories of manufactured goods, work in progress, and raw materials. According to Doucette (2001) inventory management can be challenging at times; however, the need for effective inventory management is largely seen more as a necessity than a mere trend when customer satisfaction and service have become a prime reason for a business to stand apart from its competition. For example, Wal-Mart’s inventory management is one of the biggest contributors to the success of the company; effective and efficient inventory management is of critical importance.
Inventory management is defined because a science mostly established art of guaranteeing that just enough inventory share is command with a company to fulfill demand (Coleman, 2000; Jay & Barry, 2006). it's mostly regarding specifying the size and keeping of stacked product. Inventory management is usually needed at completely distinct spots within a service or within multiple spots of a supply network to guard the standard and planned course of production up against the random disruption of running low upon materials or product. The scope of inventory administration also concerns the good lines between replenishment period interval, carrying costs of inventory, asset management, investment forecasting, inventory valuation, selection visibility,

Inventory or stock refers to the goods and materials that a business keep for the final purpose of resale or manufacturing. Inventory is a major part of the supply chains. In the manufacturers, inventory includes raw materials used to make and collect products. In resellers, it includes products that acquire to resell to customers. In either case, we need inventory to earn revenue. There are five basic reasons for keeping an inventory, which is Time, Seasonal Demand, Uncertainty, Economies of scale, and Appreciation in Value. Inventory proportionality is the goal of demand-driven inventory management.
