Control Strategy A Joint Framework

The SC process is disturbed by all those external changes in the marketplace (i.e., demand, prices, cancellations, returns, interest rates, materials availability and costs) and also by the dynamics of internal SC operations (i.e., processing times, equipment breakdown, material consumption). The information about these disturbances as well as the information required to describe the current state of the SC (i.e., stocks, capacity availability, loans, sales, accounts receivables and payables, etc.) are captured and sent as input to the controller. 

The controller is composed by a forecasting module and a control algorithm. Using the disturbances data collected, estimations of parameters in future periods are produced by the forecasting module. For those parameters which are considered
