Finally, figure 10 shows distribution orders, production and purchase for each manager in the supply chain compared, with the demand signal.

Therefore, at the end of the week the RDC restores it’s the planned stock levels. Also some special seasons where some production needs to be cadea in advance to avoid production overload. In particular, the volume growth in Russia, China, Brazil and Thailand contributed to advances in market share. Extensions of the flagship Pepsi trademark helped to drive growth in a variety of local markets. I believe that production used to do a good job, same as sales This oscillatory distortion is explained next.

Operations Management, Manchester Busines School. In principle, the forecast is produced by operational managers using econometric standards, and the sales managers are responsible of fine tune it with expected demand volumes per zone and by product.

In fact, with one week of phase lag. The bullwhip effect is attributed mainly to two causes: They are sure that innovation was the driver of that growth, because in fact PCNA brought an array of new products to the marketplace. They have more thansales points. I have my own policy of inventories. In table 3 we can see the stock movement in the RDCs.

Notice for instance that during the 25th week, demand is low just after the summer season, which is amplified by distribution and production. This is because the coverage policy is 3 days of demand. As with any other beverages companies, EMSA is mainly interested in perfect order policies.


In the hypothetical infinite order delay pipeline delay nothing happens to the output latio the delay time has elapsed. The bullwhip effect can drive wrong decisions when the production or ej capacity is defined.

An optimal policy will manage an equilibrium point latiyo the variation of order quantities will be economical and equivalent to variations in inventories. They recognise that their main business is distribution since advertising depends on PepsiCo Headquarters. In our case the study behaviour is the Bullwhip Effect, and the causes of the behaviour are defined by the policies of the supply chain managers, that make decisions based on a given flow of information.

It can happen that a low forecast causes lost sales resulting in a difference between sales and ‘real’ demand.

We shall say that the maximum demand is for 60, units, that is, 20, units less than the previous policy, with the advantage of stability for the supplier. Work in process inventories is equal to 0 units, because production time is always less than a week.

We have shown that is possible to build such a model and to capture with relative simplicity but high degree of abstraction the complexities of a Supply Chain. Changes in forecast Now suppose that we could develop a forecast system that provides information for two weeks in advance, in such a way that the purchase manager can order raw materials in advance to receive them the week when they are needed.

Efecto Latigo by Manuel Granados on Prezi

Scenarios included changes in forecast policies and purchase orders. For this strategy it is central to keep the continuous expansion of its product latgo.

The production manager also decides about external production of components, specially for bottle production. The average level of education reached by a salesman is secondary school.


… more than classic ‘beer game’.

In Mexico most of the producers are state owned. I believe that we never follow them This is a case study about the modelling of a supply chain decision structure of a Mexican bottling company.

Purchase managers are also responsible for the supply of aluminium cans and plastic or glass bottles. The amplitude and frequency of these oscillations are uncorrelated with market oscillations. This delay may be modelled using a number of levels that equal the number of time steps in the delay time, i. Therefore, nothing is in process at the end of every week. That is, keeping inventories in all possible retailers, since product substitution against the competition is very frequent.

For instance, the SD model can be extended to study scenarios where more information flows are available, where some conflict of interest affecting the policies between internal and external managers are considered, such as performance measurements.

From figure 8 it is possible to see that finished goods inventories at the RDCs move before the finished goods efrcto the DCs. Even though the bullwhip effect has decreased we cannot declare it to be solved. Conclusions and further research In this paper it was not our intention to develop a technique to define the best policies, nor the best way to define new policies in order to improve supply chain behaviour.
