Supply replenishment points

The only way to avoid this is by strict analysis of the supply chain from the customer order to final product delivery. Definition of the optimized (theoretical) process and sequential work towards a high service level approach allow the identification of gaps, and of opportunities which might not always be the cheapest (ship versus train versus plane) but could be the most effective way to reduce capital costs and shorten planning scope - an important aspect, especially in volatile customer markets with long production processes on the (chemical) supplier side. As in the case of CIP, this needs clear parameters, KPIs, commitment from all players, and regular tracking. The most important parameters are the lead time for all products, optimal lot sizes, replenishment points, and safety inventories. 

It liberates vapors (4) of the inhibitors whose particles are transported via diffusion to the article and adsorb on its surface resulting in layer 5. Liberation, transportation and adsorption velocities of the inhibitor on the article surface should be reasonable from the point of view of protecting the article against corrosion. This means that formation of adsorption layer 5 is to occur before the onset of the corrosion process or at least before it becomes stationary. Since the protecting system is not absolutely leak proof, losses of the inhibitor from layer 5 may occur. New inhibitor supplied from composite 3 replenishes this unavoidable volatilization of the inhibitor vapors. The adsorption equilibrium in layer 5 is in line with the schema ... 

Data. Working with data is a challenge for all. In traditional, supply-centric processes, the most common data input is customer orders. The second most common data source comes from customer shipments, or replenishment data. While market data—point-of-sale (POS) data and channel shipments—is growing in frequency and availability, it is not being effectively used today in 95 percent of organizations. Ironically, in the consumer products industries, POS data has been available for 32 years, but fewer than 10 percent of companies use channel data to drive their demand forecasts. 

Consumption Use of material at points in the supply chain. These are replenished by "pull" signals throughout the chain. 

Note also that the last example in the chapter essentially entails determining the placement of safety inventory in the supply chain (since the reorder point specifies inventory carried over and above the level required to meet expected demand over the replenishment lead time), albeit a simple, serial supply chain. Magnanti et al. (2006) present a general formulation of fhis problem, specifically a non-linear optimization formulation subject to linear constraints, to solve for the optimal placement of safety stocks in a general supply chain network. Magnanti et al. actually generalize the problem... 

Supply chain visibility— According to Blackhurst et al. (2005) supply chain visibility refers to the sharing of information in real-time across the supply chain stages and among their partners. The net effect of visibility is to make the supply chain more responsive, increase availability and reduce inventory risk. For example, Dell shares customer demand information with its suppliers so that they can maintain proper inventory of needed parts. Wal-Mart shares points-of-sales (PoS) data with its suppliers so that they can forecast and plan their replenishment strategies. 

As pointed out by Charnov et al. (1976), foraging animals tend to depress the availability of resources through their foraging activities. Thus, effective resource distribution may depend upon the manner in which foragers search for, exploit, and depress resource units. We separate resource depression states into four major classes (i) the resource unit is removed from the foraging site coincident with its exploitation, (ii) resource remains within the sensory field but has no resource value (e.g., an already mated female), (iii) resource remains within sensory field and replenishes itself (e.g., flower produces new nectar after original supply has been extracted), and (iv) resource becomes less vulnerable to attack and/or exploitation as a result of previous use (e.g., previously damaged birch leaves Haukioja, 1980). 

The approach adopted was to move most of the parts to point-of-use storage, managed directly by those doing the rebuilds. These technicians are responsible for building up their own kits and reordering replenishment parts to the supply chain. This approach was not implemented without some... 

Products that are relatively inexpensive and do not change much exhibit stable demands. They are also known as functional products. At the other extreme are products that evolve rapidly due to new technology and/or new composition, positioned for volatile demand, and are expensive. They are known as innovative products, and companies need to be very responsive to customer needs to remain competitive in such products. As Fisher (1997) points out, the stmctuie and operations of supply chains for innovative products need to be markedly different from those of functional products in terms of inventory positioning and replenishment, capacity configuration, logistics contracts, information sharing, and collaboration.
