Supply chain dynamics

Finally, all of the case chapters recognize customer centeredness as an imperative for successful organic growth. Each, to one degree or another, describes careful and detailed analysis of customer requirements as the primary consideration in the design of products, services, operations, supply chain dynamics, and customer support systems.

The biggest impact on the supply of parts on time was clearly the way the incoming unserviceable turbines were treated. Previously, these units were fed into the process to balance the workload of the whole operation. This meant that turbines could wait several days in the fully assembled state before being disassembled. Although this workload buffer was effective in managing capacity, it caused a major delay in the supply chain dynamics.

Modeling these problems require extensive information from key components of supply chain to characterize these components individually and collectively. Depending on the approach and its underlying objective, research effort that has been undertaken to address supply chain operation problems can be classified into two main t5q)es. The first type of supply chain operation research entails process simulation of various supply chain entities to capture the supply chain dynamics. In general, supply chain simulation models involve mathematical representation of the characteristics of these individual supply chain entities as well as behavioral relationships among them.

In another setting, the human players are provided with global information about the system. This means that all players are informed about inventory levels and orders placed for each of the components of the supply chain. Furthermore, they are encouraged to work out co-operative strategies to deal with the dynamics of the system. Compared to the local information structure, this usually results in lower inventory levels and less out-of-stock-situations for all participants. Typically, the stocks and the number of orders in this setting are much lower, resulting in much lower costs for operating the supply chain and lower costs for each player as well.

There are different ways in which an ICS can be implemented, however. The example above is illustrative of an endogenous form of ICS where producers are actively involved in ICS management. At the other end of the spectrum is an exporter-led model, whereby a buyer organises producers and controls the ICS through the implementation of external guidelines to regulate the supply chain and outsourced farmers (Pyburn 2004). Further research is needed to better understand the impacts and dynamics of these different expressions of ICS.

A sound approach for operational optimization of supply chains is to conceptualize them as dynamic systems and to apply classic knowledge of control theory to operate them (Perea-Lopez et al, 2001 [3]). Among many approaches. Model Predictive Control (MPC) frameworks have been proposed for supply chain operational management (Bose and Pekny, 2000 [4], Perea Lopez et al., 2003 [5], Mestan et al, 2006 [6]). 

Provimi Pet Food is the pet food division of Provimi, one of the world s largest animal feed manufacturing and commercial companies. The dynamic growth of the company in the last years resulted in the necessity to optimize the supply chain. The supply chain problem has special characteristics such as special logical constraints of homogeneous transport, complex cost function, and large size. The developed mathematical model and computational experiences are presented here.

The power dynamics along the supply chain appear to put buyers at a disadvantage. Some retailers express frustration that they do not receive adequate information from their chemical suppliers and wish information were more forthcoming, particularly pertaining to new materials being developed (Thorpe, 2003).
