Overview[ edit ] Business operations encompass three fundamental management imperatives that collectively aim to maximize value harvested from business assets this has often been referred to as "sweating the assets": Increase the value of the business assets Secure the income and value of the business The three imperatives are interdependent. The following basic tenets illustrate this interdependency: The more recurring income an asset generates, the more valuable it becomes.
In the decades after the two world wars, the techniques were more widely applied Operational research essay problems in business, industry and society. Since that time, operational research has expanded into a field widely used in industries ranging from petrochemicals to airlines, finance, logistics, and government, moving to a focus on the development of mathematical models that can be used to analyse and optimize complex systems, and has become an area of active academic and industrial research.
This revealed unappreciated limitations of the CH network and allowed remedial action to be taken. In the World War II era, operational research was defined as "a scientific method of providing executive departments with a quantitative basis for decisions regarding the operations under their control".
About operational research scientists worked for the British Army. Early in the war while working for the Royal Aircraft Establishment RAE he set up a team known as the "Circus" which helped to reduce the number of anti-aircraft artillery rounds needed to shoot down an enemy aircraft from an average of over 20, at the start of the Battle of Britain to 4, in Britain introduced the convoy system to reduce shipping losses, but while the principle of using warships to accompany merchant ships was generally accepted, it was unclear whether it was better for convoys to be small or large.
Convoys travel at the speed of the slowest member, so small convoys can travel faster. It was also argued that small convoys would be harder for German U-boats to detect.
On the other hand, large convoys could deploy more warships against an attacker. Their conclusion was that a few large convoys are more defensible than many small ones. As most of them were from Bomber Command they were painted black for night-time operations.
At the suggestion of CC-ORS a test was run to see if that was the best colour to camouflage the aircraft for daytime operations in the grey North Atlantic skies.
Other work by the CC-ORS indicated that on average if the trigger depth of aerial-delivered depth charges DCs were changed from feet to 25 feet, the kill ratios would go up.

Blackett observed "there can be few cases where such a great operational gain had been obtained by such a small and simple change of tactics". All damage inflicted by German air defences was noted and the recommendation was given that armour be added in the most heavily damaged areas.
This recommendation was not adopted because the fact that the aircraft returned with these areas damaged indicated these areas were not vital, and adding armour to non-vital areas where damage is acceptable negatively affects aircraft performance.
Their suggestion to remove some of the crew so that an aircraft loss would result in fewer personnel losses, was also rejected by RAF command. They reasoned that the survey was biased, since it only included aircraft that returned to Britain.
The untouched areas of returning aircraft were probably vital areas, which, if hit, would result in the loss of the aircraft. When Germany organised its air defences into the Kammhuber Lineit was realised by the British that if the RAF bombers were to fly in a bomber stream they could overwhelm the night fighters who flew in individual cells directed to their targets by ground controllers.
It was then a matter of calculating the statistical loss from collisions against the statistical loss from night fighters to calculate how close the bombers should fly to minimise RAF losses. By comparing the number of flying hours put in by Allied aircraft to the number of U-boat sightings in a given area, it was possible to redistribute aircraft to more productive patrol areas.
Comparison of exchange rates established "effectiveness ratios" useful in planning. The ratio of 60 mines laid per ship sunk was common to several campaigns: They analysed, among other topics, the effectiveness of artillery, aerial bombing and anti-tank shooting.
You can help by adding to it. March With expanded techniques and growing awareness of the field at the close of the war, operational research was no longer limited to only operational, but was extended to encompass equipment procurement, training, logistics and infrastructure.
Operations Research also grew in many areas other than the military once scientists learned to apply its principles to the civilian sector. With the development of the simplex algorithm for linear programming in  and the development of computers over the next three decades, Operations Research can now "solve problems with hundreds of thousands of variables and constraints.
Moreover, the large volumes of data required for such problems can be stored and manipulated very efficiently.MCCCD Directory. Use the MCCCD Directory to search for Faculty and Staff district-wide.
