Consider the various forecasting methods in Exercise 2.6. Compute their forecasting errors using MAD and BIAS. Based on the forecast errors, which method would you recommend and why?
Exercise 2.6
The monthly sales data for the year 2011 for Datastream, Inc., which produces network routers for small companies, are given in Table 2.18. The sales manager wants a forecast of sales for the first quarter of year 2012 (months 13-15). Compute the forecasts using the following methods:
(a) Last value method
(b) Averaging method
(c) Three-month moving average method
(d) Exponential smoothing with α = 0.25
(e) Holt's method with α = 0.4 and β = 0.5
(f) Given the sales pattern for 2011, do any of these methods seem inappropriate for obtaining the forecasts? Is there another method you would recommend to get a better forecast for months 13, 14, and 15.
The water is now let out through the nozzle splashing out to the ground until the pipe is empty. Find the water's initial exit velocity, the average kinetic energy in the exit flow, and the total entropy generation for the process.
The roadway is to be widened which will require a slope face cut at a steeper angle. Assume zero cohesion along the joints. What engineering parameter must the joint surfaces possess (magnitude) to be stable
Calculate the density in g/cm^3 of Ba and its atomic radius.
A gas mixture consists of 5 kg of O2, 8 kg of N2, and 10 kg of CO2. Determine (a) the mass fraction of each component, (b) the mole fraction of each component, and (c) the average molar mass and gas constant of the mixture.
English bond is a type of brick laying technique. explain how its laid
Problem: A 24F-V4 Douglas Fir-Larch glulam is used to span 32 ft, carrying an ASD load combination (D+S). The load is uniform over a simple span, and the beam is laterally supported so that lateral torsional buckling is prevented.
The upstream velocity is 6.5 m/s. Estimate the drag force and the lift force acting on the plate. Indicate clearly the sign convention. You may have to draw more streamline and equipotentials to obtain a good accuracy
Why does self-heating cause a problem with RTDs? Why is it of lesser importance with thermistors?
Check the adequacy of the wall. Determine a suitable wall geometry if the given geometry is unsatisfactory. Sketch a drainage scheme for the wall.
The four forces shown act on the rollers of an in-line skate. Determine the equivalent force-couple system, with the force acting at O (the ankle joint of the skater).
Resolve F into components along the u and v axes and determine the magnitudes of these componentss.
The intercooler in the previous problem uses cold liquid water to cool the nitrogen. The nitrogen flow is 0.1 kg/s, and the liquid water inlet is 20?C and is setup to flow in the opposite direction from the nitrogen, so the water leaves at 35?C. F..
