Seasonal Trends In Supply Chains
نویسنده
چکیده
Supply chains in industry have a very complex structure. The influence of many parameters is not known. Therefore the control of the material flow is rather difficult. In order to recognize these relationships between the parameters, initially very simple models have to be established. For this examination a linear supply chain with 4 stages will be designed. In all stages the stock is closed-loop controlled to a nominal stock. In particular, the seasonal trend on the control is considered. Therefore the only decision which can be done in the entire supply chain is the quantity of an order. It will be shown that the period of the trend has a significant influence to the quality of the controlling. A good quality of control results only for long periods of the seasonal trend.
