This recommendation was not adopted because the fact that the aircraft were able to return with these areas damaged indicated the areas were not vital, and adding armour to non-vital areas where damage is acceptable reduces aircraft performance.
SIMULATION AND OR (OPERATIONS RESEARCH) IN COMBINATION FOR PRACTICAL OPTIMIZATION
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. Blackett's team made the logical recommendation that the armour be placed in the areas which were completely untouched by damage in the bombers which returned.
They reasoned that the survey was biased, since it only included aircraft that returned to Britain. The areas untouched in returning aircraft were probably vital areas, which, if hit, would result in the loss of the aircraft.
When Germany organized its air defences into the Kammhuber Line , it was realized 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 minimize 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: German mines in British ports, British mines on German routes, and United States mines in Japanese routes. They analyzed, 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.

He has authored nine other books. Yadav A.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". Operational research may have originated in the efforts of military planners during World War I convoy theory and Lanchester's laws. Percy Bridgman brought operational research to bear on problems in physics in the s and would later attempt to extend these to the social sciences.
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.
