Companies, in short, were not aware that improving relations with both suppliers and customers end assumed to reach a greater volume of business and at a lower cost. Currently, meet the real demand of the consuming public is the main goal of most of the companies, at the same time that minimize the delivery times, the amount of stored goods and costs. To meet these ends, many use called pull method of logistics management. According to this system, the demands of the market dictate the functioning of enterprises, including its logistics. The production is now based on actual demands that allow to know, for example, who will be the final consumer of a product that is beginning to produce.

Of economies of scale has passed a more limited production, which reduces the stocks in the warehouses and the costs required to maintain them. However, the market wasn’t able to consume such quantities, and customers did not feel satisfied, since their tastes and preferences were not taken into account. Produced the so-called whip effect: higher production, more stock and retail service the truth, that there are many enterprises, especially SMEs in the Venezuelan case that have neglected the importance of having a good logistics, much of this product in the absence of a good organizational culture, not considering its scope, what this represents, in addition to not have some means to optimize its function. Unaware of some managers, logistics coordinates and planned various activities in order that the product reaches its final user in time, shape adequate and at the lowest cost and effectiveness possible El Dr. David Simchi-Levi, prolific researcher of logistics and Professor at the Massachusetts Institute of technology, defined a clear and precise logistics as: a set of approaches used to efficiently integrate suppliers, manufacturers, stores and shops so that merchandise will occur and spread in the right amounts, at the right places and at the right time in order to minimize the overall costs of the system, at the same time that service level requirements are satisfied.

Cattleya Plant

Flowers sprout above the pseudobulbs (example Encyclie), at its base or the same pseubobulbo (Erie example). The variability of form of different orchids, nature is dictated by the fact that often have to live in extreme conditions. This makes Orchid belonging to the same genus, have adapted the body itself in extremely different ways. Here are some examples: Dendrobium cucumerinum what has transformed their leaves in sort of sausage to accumulate water reserves to survive periods of drought. Dendrobium senile whose shaft is coated by a thick fluff that serves the plant to limit perspiration and therefore the dehydration. BLADES can be arranged in several ways in the plant. They are normally alternate in the shaft and the shape can be very various: elliptic, lanceolate, linear, triangular, etc. Often they are fleshy and in this case assume the function of organs of collection in the vegetative rest periods.

ROOTS the roots of orchids are different according to gender. We see in detail: orchids stocked only aerial root (epiphytic orchids) what grow enclaved trees used as backup. The roots are in the air and have the feature of having a type of headgear in the terminal part and are coated by a spongy tissue called velamen what endowed of chlorophyll, photosynthesis develops and absorbs damp vapor of the atmosphere. The best-known and remembered epiphytic Orchid types are: Cattleya, Vanda, Odontoglossum. Well firm and in-depth orchids on the ground (terrestrial orchids), disseminated in climates warm, where the roots are firm on Earth and through them, the plant absorbs nutrients. There are so-called formations in terrestrial orchids tubers formed from the merger of some roots that we can find black color when they have fueled the year-round or white button when they are intended to provide nutrients to the button of the following year. They are typical ejemplo:Cymbidium, Cypripedium, Paphiopedilum. There are also the intemedias which are semiepifitas orchids, plants that live on the branches and trunks of other plants or litofilas or rock what live on rocks covered by a subtle layer of fragments plants, mosses and lichens that have roots that are intermediate between those epiphytes and those landmines.
