Write a paper that includes the following:
Determine Riordan’s manufacturing strategic positioning and explain its effect on the electric fan supply chain.
Create a process flow diagram for the electric fan supply chain.
Select two metrics to evaluate performance of the electric fan supply chain.
Create a sales forecast using the expert judgment forecasting technique.
Develop an aggregate production plan, master schedule, and materials requirement plans for electric fans based off your sales forecast.
Describe how sales and operations planning would enable Riordan to maximize profitability.
Explain the effect on Riordan if a key piece of equipment went down on their electric fan production line creating a bottleneck that leads to a 5% capacity reduction. Engineers estimate it will take 4 weeks for this piece of equipment to be repaired. How would this impact the aggregate production plan, the master schedule, and ultimately Riordan’s customers? What are some short-term solutions to the 10% capacity constraint?
[en] Melexis specializes in developing robust sensorless actuators integrated circuits for automotive applications like water-oil-fuel pumps, engine cooling fans and hvac (heating, ventilating, and air conditioning) blowers.
This master thesis intends for the iterative development of a realistic electro-mechanical system model for existing hvac blowers, controlled without sensors (sensorless control loop), via electronics that measure motor current and motor voltage (self-sensing solution). It aims to predict the behavior of the fan for various control algorithms. Purpose is to accelerate future designs with efficient and robust control algorithms for self-sensing fans and pumps.
In order to reach these objectives, the first step is to select the modelling tool, then to create a model (first in open-loop, then in closed-loop) with available BLDC (brushless direct current) motor systems knowhow from Melexis application engineers. This is done by performing iterative fitting with real system behaviour and simplifying the model to the essence.
Furthermore, this document presents a way to find the electrical and mechanical motor’s parameters which are necessary to run the model. Finally, the model allowed to perform a parametric analysis for hvac blowers enabling to better understand the key parameters influencing the behavior of such systems.

This project will display the configuration, development, advancement, control and assessment of an automatic switching speed electric fan. This further venture of a smart electric fans than before that utilizing "clever innovation''. The microcontroller base programmed fan framework introduced in this task is obliged to satisfy the necessity of advances "tomorrow will be better than today". The electric fan naturally switches the speed as indicated by the environment temperature changes. Generally, electronic gadgets create enough heat due to internal loss. There is a necessity to decrease heat to so that electronics devices won’t lose their characteristic. The heat can be minimized in various methods. One of the method is temperature dependent dc fan implementing microcontroller. When environment temperature sensed by the sensor crosses the threshold value fan is switched on and temperature is reduced. The fan will remain on till the temperature reduces below the threshold value. This general idea is used in this project.
Called the , it uses a small fan powered by an electric motor which draws the cloth towards its heated base, through a combination of direct suction and the lowering of air pressure between fabric and plate. Steam is generated in a chamber above the plate, which is blown onto and through the fabric by the internal fan to remove the creases. The steam is then re-cycled back into the body of the iron by the fan.
