Organic Chemistry

1Formular the problem, put the situation (s) (s) already defined (s), nested if necessary in the form of problem, looking first solve the most critical and / or more viable in the opinion of management. This step is tricky since a high percentage of the solution is given by a sound approach, the wrong approach may lead to disastrous consequences for the organization. If I think about saving some money in this difficult time for business, I can do at any given time sacrificing service, if however, this can be reversed against my company in the medium to long term.

2 - Build model, somehow represent the problem to our case, mathematically, be aware that the best model is not necessarily the newest or the most complicated,well the model is measured by the way this reality and interprets the aid that can provide the decision maker.

3 - Collect data, this is one of the most wasteful and where help is needed from all areas of the organization, in case we need to know inventory maintenance costs and order, demand, time delivery from our suppliers, so the information we need is extensive and its quality depends on the validity of the model, as parodying systems engineers, if garbage in, garbage out. If this is true when "fed" a computer fortiori true in quantitative models.

4 - Solve the model, this is actually the easy part, if the above steps are properly carried out, is to work with data collected in the form previously built in this part some authors recommend driving scenarios, ie the data do fluctuate collected to analyze the possible influences of these changes and be alert in case the display, others recommend,be possible to see how the model behaves in situations that have already happened, in order to verify how far we have helped to make the best decision under the circumstances.
5 - Interpretation of results in this part of the management approach is essential because, NOTHING can replace entirely the opinion of the decision maker, the idea of the model is support, not replace the decision maker, here it is essential that whoever decision maker will shed prejudices and see the solution as objectively as possible, to not think that in proposing different solutions to the model that has been implementing this or previous decisions do not work. The true professional, can occur from attaining a college degree and / or experience and study in the field related to their work, what really sets it apart is its ability to analyze and evolve with the time.

7 - feedback and recreate the model, taking into account the circumstances of the environment or business may change, it is essential to be constantly checking the model, which does not detract from validity and shows seriousness and objectivity in making decisions, remember that or even "the most complex computer packages can let them decide," always the decision maker is the manager, this applies even more in terms of management models.

This part will create the model suggested in the broad sense of the word, however, it is important to emphasize that with regard to inventories most of them in there, so it is not usually necessary to "discover the warm water, so important is knowing when and where to use it. The models must afford to make mistakes on paper, decreasing the likelihood of such acts in real life, computer applications allow us to quickly see many options by simply changing the numbers according to reasonable assumptions we use in situations that may occur in the company.

6 - Implement the model, if the above steps were handled correctly, this should be the simplest, however, in practice occasionally presents problems for the rejection of some parts of the organization to change, because in all levels of the organization is common to see people not get out of preset routines, oppose and delay the implementation of new ideas.

In business there is a reality recognized by many, but unfortunately rationalized and implemented by few "who buys or sells or produces well." Having a good procurement policy, we will allow a fluid to the company management and lower costs , which obviously will improve its profitability. Because of this inventory should be studied from the time the purchase is planned, that is involved in the process of planning the company and its binding counterpart, control.

In the broadest sense of the word, inventories are usable resources are stored for later use at any given time. Some authors simply defined as idle assets in storage to use. Other authors define it as a current asset of vital importance to the functioning of the company.

There are many arguments to justify the possession or inventory, of which mention just a few.

S ystem fixed quantity: Q
I na continuous review system or system Q, the inventory level is evaluated after each transaction or continuously.
W hen the inventory level drops to a predetermined point or reorder point, put a fixed amount of order. As the order quantity is fixed, the time between orders varies depending on the random nature of demand

1.The level of service is the probability that all orders are filled with material stored during the lead time for replenishment reorder cycle.
2. The service level is the percentage of demand that is satisfied by the stock during a specified period (eg one year).
3. The service level is the percentage of time the system has available stock.

Reorder Point:
The reorder point is based on the concept of a probability distribution of demand during lead time. When an order has been lifted, the inventory system is exposed to that until you have one missing. Since the reorder point is generally greater than zero, it is reasonable to assume that the system will not be missing until an order has been lifted, the only risk of missing occurs during the replenishment lead time.
The figure shows a typical probability distribution of independent demand for delivery time. The reorder point in the figure can be placed high enough to reduce the likelihood of there being missing until any desired level. However, when calculating this probability, it will be necessary to know the statistical distribution of demand during lead time.
For pedagogical purposes, assume that the demand distribution is normal.
(assumption quite often and adjusted to reality)

The stock management, is responsible for what, the "how" of "when" and "at what price."
This action commits the overall business direction and marketing departments, commercial, manufacturing and purchasing.
The warehouse management should implement the principles that have been decided in inventory management, optimizing the corresponding physical flows within the.
Store design
To define the appropriate design of a store, you must consider:

To be stored
Financial resources available
Logical Design of Operating
Projected requirements
Types of Inventory:
According to the characteristics of the firm found five types of inventory.

Inventory of Goods:

Inventory of semi processed or finished products:

Inventory of Goods in Process Manufacturing:

Inventory of Raw Materials:

Inventory Supply Factory:
