Question: Consider the situation of the emergency room mentioned in Problem. Determine the sequence in which patients should be treated in order to minimize the weighted value of the mean flow time.
Problem: Six patients are waiting in a hospital emergency room to receive care for various complaints, ranging from a sprained ankle to a gunshot wound. The patients are numbered in the sequence that they arrived and are given a priority weighting based on the severity of the problem. There is only one doctor available.
a. Suppose that the patients are scheduled on an FCFS basis. Compute the mean flow time and the weighted mean flow time, where the weight is the priority number associated with each patient.
b. Perform the calculations in part (a) for SPT sequencing.
c. Determine a sequence different from those in parts (a) and (b) that achieves a lower value of the weighted mean flow time.
Problem: A sector with central angle θ is cut from a circle of radius R = 6 inches (see figure), and the edges of the sector are brought together to form a cone. Find the magnitude of θ such that the volume of the cone is a maximum.
A gilt and a corporate bond have the same principal and the same coupons and coupon dates. How will their prices compare?
Let x4y3 - ty + 2 = 3xt2 - x7, where x is a variable and y and t are parameters. Check whether the two conditions of the Implicit Function Theorem hold at point A = (1, 1, 1)
Estimate the population total by using "the estimator based on partial selection probabilities" (modified Hansen-Hurwitz estimator). Estimate the variance
A $1000 bond that pays annual coupons at 4.5% redeems at par in exactly 3 years from now. If the yield to maturity is currently 5%, calculate the price change (?P), predicted by modified duration, for a 100 basis point decrease in yield.
