Manufacturing Resource Planning (MRP II) - Integration of manufacturing with IT

MRP and MRP2 are predecessors of ERP. An effective organization works with a unified database system. This post is intended to explain the need and benefits of such systems.   I. Definition: " MRP II is an integrated information system that synchronize all aspects of the business." MRP II system co-ordinates: Sales Purchasing Manufacturing Finance and; Engineering by adopting a focal production plan and by using one unified database to plan and update activities in all the systems.   Divisions: MRP can be divided into three parts which are composed of: Product Planning functions which take place at the top management level Operations planning handled by staff units Operations control functions conducted by manufacturing line and staff supervisors   Checkpoints among the three divisions provide feedback regarding adequacy of overall resources completeness of resource commitments quality of performance in carrying out the plans   Advantages of MRP II: MRP information systems helped managers determine the quantity and timing of raw materials purchases. Information systems that would assist managers with other parts of the manufacturing process, MRP II, followed. While MRP was primarily concerned with materials, MRP II was concerned with the integration of all aspects of the manufacturing process, including materials, finance and human relations. MRP is concerned primarily with manufacturing materials while MRP II is concerned with the coordination of the entire manufacturing production, including materials, finance, and human relations. While MRP allows for the coordination of raw materials purchasing, MRP II facilitates the development of a detailed production schedule that accounts for machine and labor capacity, scheduling the production runs according to the arrival of materials. Process: It involves developing a production plan from a business plan to specify monthly levels of production for each product line over the next five years. (Long term planning) Production department is then expected to produce at the committed levels, sales dept to sell at these levels and finance department to assure adequate financial resources to built this product. Production plan guides the master schedule and gives the weekly quantities of specific products to be built. If capacity is not adequate, then the schedule or capacity is changed. Once settled, this MPS is then used in MRP to create material requirement and priority schedules for production. Then the CRP assures that capacity is available at scheduled time periods. Execution and control activities ensures that master schedule is met.   Important terms and concepts: The forecasting function seeks to predict demands in the future. Long-range fore­casting is important to determining the capacity, tooling, and personnel requirements. Short-term forecasting converts a long-range forecast of part families to short-term fore­casts of individual end items. Resource planning is the process of determining capacity requirements over the long term. Decisions such as whether to build a new plant or to expand an existing one are part of the capacity planning function. Aggregate planning is used to determine levels of production, staffing, inventory, overtime, and so on over the long term. For instance, the aggregate planning function will determine whether we build up inventories in anticipation of increased demand (from the forecasting function), "chase" the demand by varying capacity using overtime, or do some combination of both. Optimization techniques such as linear programming are often used to assist the aggregate planning process. Rough-cut capacity planning (RCCP) is used to provide a quick capacity check of a few critical resources to ensure the feasibility of the master production schedule. Although more detailed than aggregate planning, RCCP is less detailed than capacity requirements planning (CRP), which is another tool for performing capacity checks after the MRP processing. Capacity requirements planning (CRP) provides a more detailed capacity check. Long range planning involves three functions: resource planning, aggregate planning, and forecasting. Intermediate includes production planning functions. The plans generated in the long- and intermediate-term planning functions are imple­mented in the short-term control. You would want MRP 2 if you want the following:
1) You want the right materials landing on the right dock with the right quantities at the right time.
2) You want your receiving, storing, assembling and shipping of product to accurately flow.
3) You want to efficiently handle the movement of materials between multiple warehouses and destinations.
4) You want to be able manage high-volume vs low-volume materials differently.
5) You want to accurately fulfill orders in increased volume Eg: Company is in the industrial goods wholesale distribution business.
Company has larger warehouses in China and in the India.
Company has 10 commercial outlets in the India and in Canada.
Each Outlet stocks high-volume products
Each warehouse aggregates product from around the world.
Company takes customer orders over the web, via customer service and walk-in outlet traffic.
Each warehouse fulfills orders from all sources.  The MRP would help operations and accounting manage material coordination around the world to ensure (1) efficiency and (2) profitability. It accomplishes these goals by providing insight into predictive purchasing, insight into material availability, and accountability of order execution. Another important concept is material costing. MRP helps provide insight into accurate material costing (product costs, freight, duties, taxes, handling, etc...). Accurate material costing provides insight into product and customer profitability.   Benefits of MRP II in engineering, finance and costing Better control of inventories Improved scheduling Productive relationship with suppliers Improved design control Better quality and quality control Reduced working capital for inventory Improved cash flow through quicker deliveries Accurate inventory records

Optimisation Explained

Though it has been more than a year for me to research in the optimization techniques, and everytime there is a new concept coming over in this field, it every single time puzzles me into finding the best method to find the best values after the global or local search. For readers who are intersested in research work can explore this field more and come up with great ideas which are sometimes from nature itself! So here is a brief overview of a common and recent optimization technique- SWARM PARTICLE OPTIMISATION:     WHAT IS SOFT COMPUTING? Soft computing techniques is nothing but a collection of computational techniques in science and engineering disciplines, which attempt to analyze very complex phenomena, for which conventional computational methods may not be suitable.   Soft computing undertake different approach compared to hard(conventional) computing in that, unlike hard computing, it has tolerance for imprecision, uncertainty, partial truth and approximation. The architectural model of soft computing is generally based on physiological phenomena, biological processes and also social and behavioural theories of human and living creatures. The principle of soft computing is the arrangement of the computation for exploitation of the tolerance of the imprecision, uncertainty approximation for achieving robustness and low cost. Soft computing does the role of identifying sharing in different agents those are able to combine distinct processes to tackle the problems in their related domains. Moreover the soft computing can be looked at as the initiation of the emerging field of concept based intelligence.     WHAT ARE THE MAJOR COMPONENTS OF SOFT COMPUTING? Artificial Neural Network (ANN) Fuzzy Logic Evolutionary Computation Artificial Intelligence Machine Learning     WHAT IS BASICALLY AN OPTIMISATION TECHNIQUE? The optimisation techniques achieve global optima with the help of local as well as global searches. Local search algorithms may converge in a few attempts but may not use knowledge of a global perspective of problem landscape. The combinations of global and local searching algorithms made intelligently for exploiting the advantages of both types by dropping the disadvantages. For building such competent algorithms in solving hard problems quickly, reliably and accurately one of the possibility is hybridization of algorithms..       PARTICLE SWARM OPTIMISATION (PSO) PSO is inspired by social cognition and behavior of bird flocking as well as fish schooling. In nature there is synergetic social behavior and cooperative intelligence present in forming the phenomenon like schooling of fish, flocking of bird and herding of animal. Even though having restricted capability of individual the difficult goal is achieved with the help of teamwork and information fusion. The individual performance is based on information sharing among many members and the information sharing among many members and the environment around. The easy behavioural interaction among individual leads the whole population towards global goal. So, accomplishing a goal by collective efforts and experience sharing among individuals nothing but swarm intelligence.   The optimization mechanism contains personal or local best, global best, position or displacement and velocity with respect to particles. The memory is utilized in keeping information of position, velocity, and the best position found in search space of the particles in current iteration. Also, every particle remembers its earlier velocity and earlier best position for applying these in its movements.   This post is meant to just give an overview of optimization technique. It will appreciable to hear fron the researchers in this field and also the interested readers who would be eager to exploit this area in their research work.

Designing Mechatronics System

According to Wikipedia, "Mechatronics is a multidisciplinary field of engineering that includes a combination of mechanical engineering, electrical engineering, telecommunications engineering, control engineering and computer engineering." When beginning with a simple mechatronics system, the following three steps are to be followed: 1. Designing of a simple system 2. Setup of the designed system. 3. Implementation of the mechatronic system Mechatronics system design: It includes an integrated and optimal design of a physical system, including: 1. Sensors 2. Actuators 3. Electronic components 4. Embedded digital control system Initial conceptual design phase: When designing a mechatronics system, it is necessary to consider the following points for building the concept and basis of your design: 1. Which problem has to be solved mechanically? 2. Which problem has to be solved electronically? 3. Decisions about dominant mechanical properties. 4. Yielding a simple model that can be used for controller design. 5. Rough idea about sensors, actuators and interface. A basic mechatronic system is made up of following components: 1. Sensing Unit: This includes the sensors, filters, amplifiers, modulators, signal conditioners, etc. 2. Controller: This part mainly senses, makes decisions and gives output commands. An accurately designed controller results in a cheaper mechatronics system. 3. Actuating unit: They include actuators like solenoid valves. Note: It is worth keeping in mind a good mechatronics system has a real system approach, in which, no after thoughts or add-ons are allowed. The mechanical part is mainly used for giving motions whereas the electronics part is used for intelligence, i.e, information processing. A badly designed physical system and a sophisticated controller, may result in bad performance of the overall system. Some examples of mechatronics system is: 1. Automatic Water Valve Controller 2. Automatic Coffee Dispenser 3. Robots 4. Remote controlled Aircraft and many more.....

World's Thinnest Electric Generator

A Generator that is Wearable!!! This is how a basic generator looks like. With a lot of moving parts, complicated functions and robust in size, it occupies a lot of space. Now take a look at this type of generator: This is the world's thinnest generator, with no moving parts. Moreover its wearable and only a few atoms thick! Concept This generator works on piezoelectricity. The word piezoelectricity simply means electricity resulting from pressure. This generator uses a piezoelectric material that produces current when stretched or compressed. Researchers at Columbia University and Georgia Tech, has shown this piezoelectric effect in atomically thin film of Molybdenum disulphide (MoS2). This is the first time anyone has shown this effect, although the property has been predicted. Working: As shown in the above fig, the blue atoms show a single layer of molybdenum and yellow spheres show sulphur atoms. When they are stretched positive and negative charges are squeezed. The device was created by placing thin layers of MoS2, a material made up of a single layer of atoms, on flexible plastic substrates and using optical techniques to determine how the material's crystal lattices were oriented. This process is required because MoS2's crystalline structure makes the material piezoelectric only in certain orientations. It is also highly polar, meaning that an odd number of atomic layers are needed to ensure the piezoelectric effect isn't canceled out. Metal electrodes were then patterned onto the flakes and the current flows as the samples were mechanically deformed were measured. Confirming theoretical predictions published last year, the team found that the output voltage reversed sign when the direction of applied strain was changed, with the voltage disappearing entirely in samples with an even number of layers. An interesting fact: What's intriguing is, Molybdenum disulphide, which is not piezoelectric in its bulk form, exhibits piezoelectric properties when thinned to layers! MoS2 is a part of family of transition metal dichalcogenides. Such films are often called 2D materials, for example, graphene. Theorists have also predicted that all materials falling under this family may exhibit piezoelectric effect when made into atomically thin films. In addition to all this, MoS2, which is brittle and ceramic in its bulk form, is optically transparent and bendable in its 2D counterpart! This work underscores how material properties change when at nanoscale thus giving more scope of development and how the world becomes different when size of material shrinks to size of a single atom! Advancements: The work, though, far from commercial due to certain drawbacks, has paved way for development and use in many applications, namely: 1. Wearable device, integrated into clothing. 2. Power sources 3. Sensors in robots 4. Human machine interfaces This new research has indeed made the adage 'compact technology', a reality!

Anti-Lock Braking System(ABS) And Electronic Brake Force Distributor(EBD)

What is Anti-lock braking system (ABS)? Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage. ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, ABS can significantly increase braking distance, although still improving vehicle control.   How does ABS work? The anti-lock brake controller is also known as the CAB (Controller Anti-lock Brake). Typically ABS includes a central electronic control unit (ECU), four wheel speed sensors, and at least two hydraulic valves within the brake hydraulics.   1. The ECU constantly monitors the rotational speed of each wheel; if it detects a wheel rotating significantly slower than the others, a condition indicative of impending wheel lock, it actuates the valves to reduce hydraulic pressure to the brake at the affected wheel, thus reducing the braking force on that wheel; the wheel then turns faster. Conversely, if the ECU detects a wheel turning significantly faster than the others, brake hydraulic pressure to the wheel is increased so the braking force is reapplied, slowing down the wheel. This process is repeated continuously and can be detected by the driver via brake pedal pulsation. Some anti-lock systems can apply or release braking pressure 15 times per second. Because of this, the wheels of cars equipped with ABS are practically impossible to lock even during panic braking in extreme conditions.   2. The ECU is programmed to disregard differences in wheel rotative speed below a critical threshold, because when the car is turning, the two wheels towards the center of the curve turn slower than the outer two. For this same reason, a differential is used in virtually all roadgoing vehicles.   3. If a fault develops in any part of the ABS, a warning light will usually be illuminated on the vehicle instrument panel.     What is Electronic brake-force distribution (EBFD)?     You’re driving at a safe speed on a moderately busy highway. It has not been snowing for long, but already the pavement is dusted with snow and becoming slippery. Suddenly, another motorist signals to enter your lane and makes a sharp veering motion. You are forced to slam on the brakes to avoid hitting the encroaching vehicle. The weight of your car is thrust forward from the heavy braking, putting added pressure on the front wheels to stop the car. Meanwhile, the sudden shift in weight has significantly reduced the amount of traction available for the back wheels. After a few seconds, the back wheels lock completely. You feel the back end of your car start to fishtail into the lanes on either side of you. Finally, the back-and-forth motion of the rear of the car overcomes the braking power of the front wheels and you spin around, face-to-face with oncoming traffic. Situations like this are potentially very dangerous. Electronic brake-force distribution is a vehicle safety feature that can prevent this kind of event.     How does EBFD work?   1. Electronic brake-force distribution is often installed with antilock braking systems (ABS). ABS installations that are supplemented with EBFD react more quickly and deliver more situation-specific braking commands than older ABS setups.   2. EBFD systems are usually made up of three subcomponents that are monitored and guided by an electronic control unit (ECU). These components include speed sensors for each wheel (sensors that monitor how fast the wheel is rotating), brake-force modulators (a mechanism that increases or decreases brake-force applied to a wheel), an acceleration / deceleration sensor that detects the vehicle’s forward and sideways acceleration/deceleration, and usually a yaw sensor (a sensor that monitors a vehicle’s movement along its vertical axis).   3. The electronic control unit interprets the information from the speed and yaw sensors, and then sends commands to the brake-force modulators. Similar to how ABS setups operate; the ECU in EBFD systems is attached to the hydraulic brake-force modulator. So, while the ECU and brake modulator serve different purposes, they are physically combined into one electro-hydraulic unit.   4. EBFD works by monitoring each wheel’s responsiveness to the brake, and then tailoring the amount of brake-force applied to each wheel. In vehicles without EBFD, when you apply the brakes the brake-force is evenly distributed across all four wheels. The danger here is that if, for example, one of your wheels is on ice and locks up, you lose 25% of your braking power. On a vehicle with EBFD, the system would sense that one of the wheels is not braking properly, and would redistribute the brake-force to the unaffected wheels to obtain optimal braking power. This way, you retain the maximum amount of braking power possible and reduce the risk of fishtailing or spinning around.   5. The yaw sensor installed with most EBFD systems also helps prevent oversteering and understeering. Oversteering occurs when a vehicle continues to turn beyond the steering input of the driver, while understeering refers to cases where the vehicle does not turn enough in response to driver commands. Both oversteering and understeering are the result of insufficient traction on the road. If you begin to oversteer or understeer, the yaw sensor will record unusual movement along the vehicle’s vertical axis, and your EBFD system will react by applying either the brakes on the inner wheel (to correct understeering) or the brakes on the outer wheel (to correct oversteering).

Diploma Project Idea- Proposed Advancement of A Pelton Wheel Turbine

FUTURE ADVANCEMENT IN PELTON WHEEL TURBINE 5.1 Introduction: The most common problem in the Pelton wheel turbine of most of the laboratories functioning is the problem in corrosion and problem in its repair during its breakdown due to its bulky nature. Common solutions for the above mentioned problems are: · Routine maintenance of Pelton wheel turbine · Careful handling of the Pelton wheel test rig · Keeping its parts lubricated regularly · Replacement of ineffective parts However there have been no permanent solutions given to such kinds of problem. So keeping in mind the inefficiency such problems cause, we have proposed a model wherein a flange with bearing is attached for rotational motion of the suction pipe. The suction pipe of Pelton wheel is constantly submerged in water which moreover increases the corrosion of the pipe. So the rotational motion of the pipe helps to lift the pipe and keep it away from water thus helping the pipe from getting corroded. The detail of the proposed model is given further. This model eliminates the cost incurred due to routine maintenance work, replacement of entire pipe and repairs. Thus this model will be helpful in the increased efficiency of Pelton wheel test rig in the laboratories. We have also discussed about the alternative methods that can be used which are readily available in market for construction of the basic concept of the proposed model. 5.2 Design of flange: A: Hub dimensions: Internal diameter of hub (d) = 120mm Outer diameter of hub (D) = 150mm Length of hub (l) = 0.5 (d) = 60mm B: Flange dimensions: Outer diameter of flange (D3) = 250mm Thickness of flange (t) = 0.2*(d) = 25 mm C: Bolt dimensions: Bolt circle diameter (D2) = 210 mm Diameter of hole for bolts (d2) = 18 mm 5.3 Design of bearing: A bush bearing is used between the two pipes in order to have motion of the inner pipe. The bush is made of Bronze. The design of bearing is as follows: Load (F) = 20 kN Speed (N) = 60 rpm Wear (w) = 0.03 mm Life (t) = 500 h From the table 5.1, pmax = 25 MPa vmax = 0.3 m/s pvmax = 1.636 MPa ms-1 From the SKF manufacturers catalogue (table 5.2), Inner diameter = 45 mm Outer diameter = 55 mm Length of bush = 80 mm We know that, p = F/dl = (20 x 103)/(45 x 80) = 5.55 MPa since 5.55 < 25 MPa, hence it is safe. v = π d N = (π x 45x 10 -3 x 60) / 60 = 0.282 m/s since 0.282 < 0.3 m/s, hence it is safe. pv = 5.55 x 0.28 = 1.554 MPa.ms-1 1.554 < 1.636 MPa.ms-1, hence the design is safe. Checking for wear, w = K x p x v x t = 30 x 10-6 x 5.55 x 0.282 x 500 =0.0234 mm. Hence, the design of bearing is safe 5.6 Other alternatives: Comparison of Flexible coupling and the stainless steel flexible pipe connector: In the market for achieving the transverse motion of the pipe we have stainless steel flexible pipe connector as shown in the figure. The cost of this stainless steel pipe connector is 157$ of 12 inch which is equal to rs.7850 which is very costly. So we have manufactured a localized flexible coupling whose cost is around rs.2040 which is very much cheap than what is available in the market. The approximate life of our coupling is around 3-4 years if kept in a good condition.

Is Mechanical Engineering Really Good for Girls?

Is Mechanical Engineering Really Good for Girls???     As I just checked my Shoutbox, I came across the most widely asked question by @Corrine Lovato: “Hello, I am 4th year High school student. And I'm going to take BS Mechanical Engineering. My problem is, I AM A FEMALE. :3 Did you think guys, it suits me? I DO REALLY REALLY LIKE AND LOVE TO BE A MECHANICAL ENGINEERING SOMEDAY.... Any Advice guys? It may help me ) Thank you!! Mechanical Engineers and to be Mechanical Engineers.”     This is the most talked about, discussed and opinionated question for every girl who wish to pursue mechanical engineering and also for every parent who is in two minds for a daughter who wishes to pursue mechanical engineering.   As soon as I finished my high school, I strongly wished to pursue “Mechanical Engineering” because I was always curious since my childhood to know how machines work and always in awe with the perfection they delivered the outcome. I believe, every girl who wishes to pursue this field goes through the following stages:     What Is Mechanical Engineering? Mechanical Engineering is a discipline in which you ought to learn something from every field of engineering. From the theory of machines to its designing, from electronics to how motors work, from programming to database information retrieval system. If I could sum it all up, I can be a branch which is a Jack of all fields. Also Mechanical Engineering is a branch where you find the least amount of girls or sometimes none at all!!       Do girls really have to go through the hard labour work while pursuing this course?? During the first two years, you have to complete your workshop duties which include working on lathe machines for manufacturing a component. It always seems tough at first, but it never is. And you always bound to get help from you fellow mates. But the finishing given to the component is always given the BEST by the girls!!!     How actually is a life as a female mechanical engineer?? Firstly, you will have very very few female friends. Most of the friends you get from other branches like computers or electronics, whom you get to meet either during lunch time or sometimes not at all! Secondly, you have no option left than to be with your male classmates. Believe me, male friends are more honest, helpful, selfless and dependable. Especially, the males who wish to uplift women than suppress them. It is always better to be focused and carve your own niche. Because in the end it’s all about you!!!       Is there any scope for girls in mechanical engineering?? As I said, in the end it’s all about you. The world is changing and so is mentality of people. After completion of Diploma in Mechanical Engineering, even being a “female”, I had a host of opportunities to work in well known companies. You can go for research work, designing, internships, teaching, shop work and anything that matches your interest. Or better you can pursue your higher studies and specialize in it. Remember :Where there is a will, there is a way!!!   Feel free to comment or ask about any doubts and questions!! Any suggestions or feedback are also welcome!
