Cost , of inventory

Just-in-Time. Just-in-time closely followed the reintroduction of SPG into the American workplace. The efficacy of JIT was limited in the United States to an emphasis on keeping component inventories low to reduce the cost of inventory (16). More importantiy, however, JIT should be used to focus management attention on quahty problems. 

The working capital includes the cost of inventories, such as raw materials, materials-in-process, products, etc as well as suppHes, accounts receivable less accounts payable, prepaid expenses, other cash needs such as payroll, and some start-up expenses, eg, materials and wages. Typical inventories can be taken as one month s supply of raw materials, products, and materials-in-process. The materials-in-process can be valued at one month s sales. Other operating cash can be estimated as the actual cash need for one month. 

Raw-materials, intermediate, and finished-product inventories Cost of handling and transportation of materials to and from stores Cost of inventory control, warehouse, associated insurance, security arrangements, etc. 

Most people agree that general expenses incurred in administration, selling, distribution, etc., should not be included in the cost of inventory. In fact, many feel that no costs should be absorbed before they have been incurred. In general, method 2 is favored by engineers and method 3 by most accountants. However, the accountancy convention is to value at either cost or market value, whichever is the lower. In the methods considered, either ac tual or standard costs can be used. Note that method 3 shows a higher profit than method 2 when sales volume exceeds the produc tion rate and a lower profit when the production rate exceeds sales volume.

This would reduce the cost of inventory space, management, and insurance (it would also result in customers receiving fresher products where this is a factor). Furthermore, in applications where certificates of analysis are required prior to shipping or acceptance, time saved may translate into material holding and/or labor savings (e. g., for truck driver s or tanker crew s idle time awaiting authorization to depart). 

Step 2. Let the business costs be split up into two categories (1) the carrying cost or the cost of inventory and (2) the cost of production. Let D be the number of units produced in one run, and let Q (annual production level) be assigned a known value. If the problem were posed so that a minimum level of inventory is specified, it would not change the structure of the problem. 

In the short term, more advanced companies meet the overall supply chain demand while simultaneously minimizing the overall costs of inventory, production, and missed sales opportunities. Further, with frozen production periods they avoid unnecessary changeovers, smoothen the whole production, purchasing, and maintenance process, and achieve superior adherence-to-plan and productivity performance. Nevertheless, if required, they can react promptly to unforeseen changes thanks to reduced changeover times, flexible suppliers, and powerful IT tools that adjust the plans quickly. 

In contrast to open formularies, closed formularies are strictly controlled. Only certain agents are available and strict therapeutic substitution with the most recognized agent within a pharmacological class is standard procedure. The purpose of this type of formulary is to assure availability of all needed products at the least cost of inventory investment. Because this mechanism of control maintains the least costly of products, it is ostensibly the most cost effective. However, significant restrictions on medication use often produce dissatisfaction and dissension among the health care practitioners and patients. Further, Horn et al. (1996) suggest that strictly controlled formularies may increase overall health care costs. 

Let = E[yp] be the expected cost of inventory policy 1 in period t. The assumption behind steady-state simulation is that as t increases. The mean plot estimates as a function of... 

Victor Fung refers to the firm s capabdity as the soft 3 of the supply chain. He explains that if a product that leaves a plant costing 1 ends up at retail for 4, the 3 represents the cost of inventory, forecast error, exchange rates, retail markup, and other factors. There is a much better chance at reducing the 3 than the 1. Li Fung focuses on creating a customized value chain for each order ([82]). This represents a classic example of a pure supply chain company. 

Extensive results have been reported in the literature on drying of wood as well. Again, all quality indicators are positive. Several vendors worldwide have already commercialized the vacuum-superheated steam-drying systems. It is noteworthy that besides enhancement of the product quality, the drying times are reduced two- to five-fold resulting in significant reduction in cost of inventory in the dryer. 

Retailers pushed supply chain costs back on manufacturers, and manufacturers pushed the costs back on suppliers. In Figure 2.8, the pushing back of inventory costs is detailed in the consumer value chain. This has happened, year over year, for the past 20 years. The cost of the total supply chain is going up. The irony is that the weaker players of this supply chain— both in brand presence and in cost of capital—are at the end of the chain. The second irony is that upstream companies are forced to eat these costs with a markup in yearly negotiations. Year over year, these added costs of inventory and write-offs become embedded in the cost of goods sold. 

Cost of inventory at site depending on the time required for obtaining fresh supplies. 

This can be done by properly recording the replacements of spares carried out and other items consumed over 6 months to 1 year. The figures for stock levels could be higher than the figures recommended by vendors and can increase the cost of inventory. However, it is better to be on the safer side. 

Spares shall be procured from original equipment manufacturer and fitted at the earliest to reduce chances of interruptions in plant activities due to breakdowns. However, some simple spare parts may be developed in-house, e.g. anti-vibration pads, level indicators, and shaft sleeves for pumps for cost reduction. Sometimes, old spares may be reconditioned and fitted to start the plant soon or if new spares are not available immediately (e.g. impeller or shaft of a blower). This approach may only temporarily save some cost of inventory as a sudden breakdown may still occur. 

It can save cost of inventory and space required and facilities required for safe storage. It needs very reliable suppliers who shall be preferably near by the premises. 

For example, if a shovel costs a hardware store 30 to purchase, the holding cost rate is 20%, the annual demand is 2,000 shovels, the order quantity is 100, and the order cost is 100, then we can calculate the total cost of inventory as ... 

Order quantity rules were created to minimize the total costs of inventory. They can be used with both independent- and dependent-demand inventories. There are a wide variety of order quantity rules, which consider many different costs and situations. One of the simplest rules and the best known is the economic order quantity (EOQ). This rule minimizes the costs of holding inventory and the costs of ordering inventory. It is derived from the inventory total cost equation given in Equation 1. 

The EOQ is that quantity which minimizes the overall cost of inventory. The variables include those in Table 28.1. 

TOP (Table of Pulls) Units of end product per day used for supply chain planning. The TOP for a product is the agreed-to peak sales level. When the TOP equals the MSR, customer satisfaction is guaranteed. Sometimes a company may lower the TOP below the MSR. This could be a tradeoff between customer service and the cost of inventory. The TOP for an end product is used to plan 3C replenishment to support the customer service objective. 

Even though the per imit cost of the item is lower with the foreign supplier, the TCO is less with the domestic suppher when we take into account the cost of inventory and cost of quality.
