Consider a network of two legs. Leg 1 services Frankfurt to London with 20 seats capacity. Leg 2 services London to New York with 40 seats capacity. Passengers may book either a single leg journey or a two-leg journey. The time until departure is 100 days, the prices of each of the 3 tickets was detailed in the question, each with a different probability of booking requests being made. At any time we can accept a requested booking or reject the booking. What is the optimal policy to maximise the expected revenue?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It turns out this problem can be solved exactly with the Bellman equation, and I wrote a small app to visualise the optimal policy.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/ulv3kh-malcolm.shinyapps.io\/STOR-i_DP\/\" data-type=\"link\" data-id=\"https:\/\/ulv3kh-malcolm.shinyapps.io\/STOR-i_DP\/\">Optimal policy visualiser<\/a>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>RTA app I created an R app to visualise UK government data on serious and fatal road traffic accidents.
