Planning drinking water for airplanes

摘要: The management of the Dutch national airline company KLM intends to bring a sufficient amount water on board all flights fulfill customer’s demand. On other hand, surplus after flight should be kept minimum reduce fuel costs. service passengers is measured with level. objective this research develop models, which can used minimize such that predefined level met. difficulty has overcome fact most available data consumption are rounded off nearest eighth tank. For wide-body aircrafts rounding may correspond about two hundred litres water. Part problem was also define good use as model parameter would give better control surplus. have been analyzed examine aspects we had take into consideration. Next, general framework developed in defined Quality Service for each flight: probability given leg. Three approaches will proposed find distribution function total flight. first approach tries fit based data, without any assumptions underlying shape distribution. second assumes normality and third uses binomial All methods validated numerically illustrated. We recommend approach, where determine an upper bound
