Demand-supply chain model

Beech s (1998) demand-supply chain model, along with Comergent s (2003) demand chain model, have each progressed towards a value chain management model (Mudimigha, Zairi, Ahmed, 2004). Sampson (2000) demonstrated that service supply chains were bi-directional, and that communication between customers and suppliers, and vice versa, must occur. Thus, a partnering between participants occurred (Vokurka, 1998). Sampson also indicated bi-directional supply chains were typically short lived, but had just-in-time implications with inherent value-added expectations. To measure such information, new metrics tools have been devised. New methods to capture online measurement data (or Web... 

A detailed supply-chain model, which showed that two days inventory was required to supply the forecast market demand, determined chlorine storage tank number and size. The minimum number of drums and cylinders of liquid chlorine required to be held on-site was also calculated from the supply-chain model. This approach was also extended to calculation of the number and size of storage tanks for products such as caustic soda, sodium hypochlorite and hydrochloric acid.

Real data from the case study described in Section 5.1 was used to list the applicability of the integrated supply chain model (Additional material is available from the CRC Press website http //www.crcpress.com/product/ isbn/9781498708586). The case study considered 24 periods, and each period was one month. The demand data used for this model were approximate... 

The supply chain model s boundary is specified by a set of assumptions and is explained in this sechon. The supply chain is assumed to operate with installation-specific ordering policies in the class of periodic review, order-up-to S policy. A single product is assumed to flow in the supply chain from manufacturer to customers. Retailers face deterministic and dynamic customer demand, and the lead hme for information processing is assumed to be negligible or zero. The model considers a finite time horizon. Time is assumed to be discrete, and a unit is assumed to be one day. This model does... 

Several simulation-based optimization models in the context of supply chain management can be found e.g. in the area of supply chain network optimization (Preusser et al. 2005) or to simulate rescheduling of production facing demand uncertainty or unplanned shut-downs (Tang/Grubbstrom 2002 Neuhaus/Giinther 2006). A basic approach of simulation-based optimization is presented by Preusser et al. 2005, p. 98 illustrated in fig. 24.
