Countless operations decisions that have both long-term and short-term impacts on the organization’s ability to produce goods and services that provide added value to customers must be made. If the organization has made mostly good operations decisions in designing and executing its transformation system to meet the needs of customers, its prospects for long-term survival are greatly enhanced. Major operations decisions areas include inventory, capacity, quality, scheduling, process type, technology, location, layout, and supply chain management. Each of these nine decision areas will be discussed in this section.

Inventory decisions

The key question that must be answered for inventory is “How much?” Understanding the best inventory levels to carry is critical to the organization because too much inventory and too little inventory are both costly to the organization. Inventory that exceeds what is needed to satisfy customer demand imposes unnecessary costs such as storage, deterioration, obsolescence, theft, and money tied up in inventory that cannot be used for other purposes. Too little inventory means the organization cannot meet 100 per cent of its customer demand and sales revenues are delayed or lost.

For example, a restaurant that specializes in serving fresh fish needs to make careful purchasing decisions so it has enough fresh fish each day to serve its customers, but not so much that unsold fish must be severely discounted or discarded at the end of the day. Computer companies such as Dell must carefully manage its computer chip inventory so it can meet current customer orders, but not be stuck with too much inventory if a new computer chip comes out or if vendors reduce prices.

Capacity decisions

The question managers must answer for the capacity decision area is the same as the question for inventory: “How much?” Determining the organization’s capacity to produce goods and services involves both long-term and short-term decisions. Long-term capacity decisions involve facilities and major equipment investments. In 2007, Airbus introduced its Super Jumbo Jet that carries up to 850 passengers and costs USD 3 billion. The Super Jumbo provides huge amounts of passenger carrying capacity, but before an airline purchases this jet, it needs to decide if it has enough passengers to generate the revenue to pay for the plane and earn profits for the airline. A large single airplane like the Super Jumbo may not be the right capacity decision for an airline that serves numerous medium sized cities. On the other hand, an airline that serves passengers traveling between New York City, USA and Shanghai, China might find the Super Jumbo to be a perfect choice for meeting demand because of the large populations in each city.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials

Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
