Through the aid of the Powersim software Study extension as the structure of the management of the warehouse can be adapted in order to represent the Supply Chain in a manifacturing industry.
Locally political it rations them that they create stable corrections to the organizational units characterizes them can, through interactions with other functions and organizations to cause to oscillations and instability.
The instability can carry to lack of confidence between the partners of a Supply Chain with consequent behaviors that get worse the same instability.
The model is developed in stages. The simplified assumptions are studied one to the time and solo after the behavior of every version is analyzed totally.
This iterativo process depends on the understanding of the fundamental relations between the structure and the behavior of the dynamic system that in the long run door to the development of effective the useful model.

Figure 4.4 extension the political diagram of structure of a manifacturing company.
The company maintains a stock of ended warehouse and satisfies the orders in the moment in which they arrive.
Figure 4.4 - Political structure of the management of the warehouse

In this model it begins them is assumed that the customers are sensitive to the delivery - the orders that the society cannot satisfy immediately are lost in the moment in which the customers other suppliers try.
In this model it begins them the orders of the customers are exogenous (that is independent from the structure of the model).
The production begins. The supply of the WIP (work in process) is increased from production starts and diminished from production installments.
The manufacturing control and the decisions taken to care of the management of the warehouse from the company include order fulfillment (implementation of the orders that determines the ability to satisfy the orders of the customers based on the adequacy of the warehouse) and production scheduling (organization of the production that determines the production rate begins based them on the forecast of the question and the position of the enclosed warehouse the WIP inventory).
The model includes three important negative feedbacks (negative feedbacks).
The Stockout loop regulated shipments and the variations of the warehouse: if the warehouse is inadequate, some articles will go supply outside and the deliveries will fall to of under of the orders.
In the event extreme the shipments will go to zero when the warehouse is emptied completely. Inventory Control and WIP Control loops modify the production in order to move the level of warehouse and WIP towards their wished level.
In this model it begins them do not consider stock of materials neither restrictions of ability.
