Design of an Ideal Plant Layout

Design of an Ideal Plant Layout
Design of an Ideal Plant Layout Approach to proper layout: When a new plant is erected, a good deal of expertise is used by management to design a proper layout. A comprehensive approach with regard to the placement of machineries, location of stores, inspection cabins, tool rooms, maintenance wings, receiving and shipping departments, toilets, canteens and other handling equipments, is necessary for achieving quick and smooth production at the least cost. There is no set pattern of layout for all plants. What is suitable for a giant plant will not be fit for a small factory. What goes well with a processing industry may not match a job industry. But, the basic principles governing a plant layout are more or less the same. Cost of Production: The all time concern of big industries is the ever rising cost of production. Their priority would be mass production or continuous production to factorise the economy of scale. This is possible where industries are involved in producing highly standardized products. Industries involved in the production of customized or specialized products, catering to premium customers, cannot go for mass production since it is not a feasible option. They have to dedicate separate lines of production for different products. Invariable of the type of production, all industries need to cut down their costs wherever possible. The only possible solution is to design a suitable layout that facilitates uniform and minimum movement of materials thus avoiding wastage, minimization of production delays and avoidance of bottlenecks. An ideally laid plant layout reduces manufacturing costs through reduced materials handling, reduced personnel and equipment requirements and reduced in-process inventory. It is amazing how industries in Japan have mastered the art of employing Just-in-time concept, which focuses on continuous improvement and increases the rate of return on investment by reducing the in-process inventory and associated costs. The importance of plant layout would be better appreciated if one understands the influence of an efficient layout on the manufacturing function. An efficient plant layout would definitely incorporate the following aspects: Economies in handling-cut down material handling costs that account for 30-40 percent of the manufacturing cost Effective use of available space-especially in urban areas, where every inch of available space is an asset. Minimization of production delays-on time delivery schedules and speedy execution will help. Improved quality control-to reach expected standards of production Minimum equipment investment-by planned machine balance and location Identification and rectification of bottlenecks-don’t allow materials to pile up at any place of production, don’t allow workers to be lethargic, keep the machines in the best of condition to speed up operations Better production control-facilitated by a planned layout Better supervision-a good plant layout enables the supervisor to have a hawks eye on the entire shop floor Improved utilization of labor-process flow should be planned in such a way that workers should be equipped all the time without any lull Improved employee morale-by providing better working conditions, employee facilities, increased earnings, reduced accidents etc. , Scope for Expansion: A good plant layout must also have scope for expansion or revision in future. Even best layouts become obsolete over a period of time, so revisions ranging from minor alterations to a complete dismantling of the existing structure and installation of a new layout become necessary from time to time. Manufacturers, who are keen to survive the global competition, must consider revising their layouts which should fall in line with technological and market...

Types of Production Systems -I

Types of Production Systems -I
Types of Production Systems -I Continuous Production What is continuous production? The manufacture of products requiring the sequential performance of different processes on a series of multiple machines receiving the material for manufacture through a closed channel. For example, continuous production is generally conducted in the paper and chemical business. Characteristics 1. Dedicated plant and equipment with zero flexibility. 2. Material handling is fully automated. 3. Process follows a fixed sequence of operations. 4. Component materials cannot be readily identified with final product. 5. Planning and scheduling is a routine action. Technical Web Testing 101- Introducing the tools, techniques and thought processes that help you become more technical, and test more thoroughly. Benefits 1. Standardisation of product and process sequence. 2. Higher rate of production with decreased cycle time. 3. Higher capacity utilisation due to line balancing. 4. Manpower is not required for material handling as it is completely automatic. 5. Person with limited skills can be used on the production line. 6. Unit cost is lower due to high volume of production. Limitations 1. Flexibility to accommodate and process number of products does not exist. 2. Very high investment for setting flow lines. 3. Product differentiation is limited. Mass Production What is mass production? The manufacture of a product on a large scale. The mass production of items is often done by using an assembly line, or another efficient means of production. The process is often carefully determined, to try to produce the greatest quantity of items while using the fewest resources (such as labor and/or time). Mass production has become popular since the assembly line became prominent in the 1900s, although the process embodies principles of efficiency that have been around much longer. Characteristics: 1. Standardisation of product and process sequence. 2. Dedicated special purpose machines having higher production capacities and output rates. 3. Large volume of products. 4. Shorter cycle time of production. 5. Lower in process inventory. 6. Perfectly balanced production lines. 7. Flow of materials, components and parts is continuous and without any back tracking. 8. Production planning and control is easy. 9. Material handling can be completely automatic. Benefits 1. Higher rate of production with reduced cycle time. 2. Higher capacity utilisation due to line balancing. 3. Less skilled operators are required. 4. Low process inventory. 5. Manufacturing cost per unit is low. Limitations Following are the limitations of Mass Production: 1. Breakdown of one machine will stop an entire production line. 2. Line layout needs major change with the changes in the product design. 3. High investment in production facilities. 4. The cycle time is determined by the slowest...
