Measures Of Effectiveness

Wednesday, March 18th, 2009

One advantage of process layouts is their ability to satisfy a variety of processing requirements. Customers of materials in these systems requires different operations and different paths through the system. Materials oriented systems necessitate the use of variable path material handling equipment to move materials from work center to work center, and in customer oriented systems, people must ravel or be transformed from work center to work center. In both cases, transportation costs or time can be significant. Because of this factor, one of the major objectives in process layout is to minimize transportation costs, distance, or time.

This is actually accomplished by locating departments with relatively high interdepartmental work flow as close together as possible. other concerns in choosing among alternative layouts includes initial costs in setting up the layout, expected operating costs, the amount of effective capacity created, and the case of modiying the system if the need arose.

Pollution

Sunday, March 1st, 2009

The term pollution refers to any unwanted contaminant in the environment that poses health risk. Environmental pollutants do not only contribute to the spread of communicable diseases but also to many chronic diseases. Rapid population growth often results to mass consumption, competition and the depletion of the natural resources, and a;though advancement in science and technology has helped mankind speed up communication and other processes, ironically, it has damaged the environment as well.

Water pollution Just like air, water is vital to life. In spite of knowing its importance to life, people keep on dumping wastes of all sorts to the bodies of water. When pollutants are channeled into non flowing bodies of water such as lakes, accelerated growth of algae results in bacterial decomposition that consumes the oxygen present.This oxygen deficit kills fish and other lakes inhabitants which are important sources of food., Polluted water can cause diseases such as cholera, typhoid fever, dysentery, amoebiasis and hepatitis.Pollution can also trigger red tide, a condition when water turns into red due to the one celled microorganisms called dinoflagellets which produce toxins that contaminate shellfish. People who happen to eat contaminated shellfish will suffer from PSP or the paralytic shellfish poisoning.
