Question 5. [22 points] GatorMove is a company that provides 3PL shipping service for GreenSeeds. GatorMove makes deliveries from GreenSeeds’ manufacturing plant to its central warehouse. Based on the historical performance, transportation lead time provided by GatorMove is normally distributed with a mean of 5 days and a standard deviation of 2 days. Currently, GatorMove charges GreenSeeds $1/unit for shipping cost. GreenSeeds use the EOQ model to determine its optimal quantity per shipment. Other relevant information can be found below: Average demand at the warehouse 150 units/day The standard deviation of daily demand at the warehouse 20 units/day Fixed ordering cost $250/order Unit cost $40/unit In-transit inventory carrying rate 15% On-site inventory carrying rate 20% Probability of not stocking out during the lead time 90% Operating days at the warehouse 360 days/year What is the total annual logistics cost (including transportation, on-site inventory, and in-transit inventory holding) associated with the current system?

Consider the closed system below. Let the controller gain Kp = [Kp], the actuator time constant ta = [ta], and the plant time constant, tp = [tp]. Find the command transfer function, C(s)/R(s), for the case where the actuator block is neglected. Then, find the root of the characteristic polynomial in the command transfer function for this case. Enter the root in Canvas with 3 decimal places. Make sure to include a negative sign if the root is negative. 

Suppose the plant shown in the diagram below has parameter values I =[I] and c = [c]. Determine the smallest value of the gain, KP, required so that the steady-state command error will be no greater than ess = [ess] rad/s if  is a unit-step input. Report your answer with 1 decimal place.

For the control system below assume that the proportional gain must be greater than zero. Determine the minimum value of KP needed for stability. Use the following parameter values: a = [a], b=[b], and c=[c]. Report your answer with one decimal place. 

For the block diagram below let a = [a] and b= [b]. Perform the following: a) Find the command transfer function C(s)/R(s) b) Find the disturbance transfer function D(s)/R(s) c) If K = [K] find the roots of the characteristic polynomial. Input the real part of one of the roots. If the real part of the root is negative, include a negative sign. Put your answer in canvas with three decimal places.
