The layout of a plant or facility is concerned with the physical placement of resources such as equipment and storage facilities, which should be designed to facilitate the efficient flow of customers or materials through the manufacturing or service system. The layout design is very important and should be taken very seriously as it can have a significant impact on the cost and efficiency of an operation and can involve substantial investment in time and money. The decisions taken with regards to the facility layout will have a direct influence on how efficiently workers will be able to carry out their jobs, how much and how fast goods can be produced, how difficult it is to automate a system, and how the system in place would be able to respond to any changes with regards to product or service design, product mix, or demand volume. In many operations the installation Continue reading

Method Study Procedure
Method study is the systematic recording and critical examination of existing and proposed ways of doing work, as a means of developing and applying easier and more effective methods and reducing costs. So it is the process of analyzing the methods involved in work flow to increase productivity. It deals with doing the work in a better way, with less time and effort. That is why it is also termed as work simplification. Method study procedure is an organized approach and its investigation rests on the following six basic steps: Select the work to be analyzed. Record all facts relating to the existing method. Examine the recorded facts critically but impartially. Develop the most economical method commensurate with plant requirements Install the new method as standard practice. Maintain the new method. The above basic method study procedure was first developed and articulated by Russell Currie at Imperial Chemical Industries (ICI). Continue reading
Intermittent Manufacturing Systems
In Intermittent manufacturing systems, the goods are manufactured specially to fulfill orders made by customers rather than for stock. Here the flow of material is intermittent. Intermittent production systems are those where the production facilities are flexible enough to handle a wide variety of products and sizes. These can be used to manufacture those products where the basic nature of inputs changes with the change in the design of the product and the production process requires continuous adjustments. Considerable storage between operation is required, so that individual operations can be carried out independently for further utilization of men and machines. Examples of intermittent systems are: machine shops, hospitals, general office etc. Characteristics of intermittent manufacturing systems are: Most products are produced in small quantities. Machines and equipment are laid out by process. Workloads are generally unbalanced. Highly skilled operators are required for efficient use of machines and equipment. In-process inventory Continue reading
Mass Production Systems
Mass production (also called flow production or repetitive flow production) is the production of large amounts of standardized products on production lines. It was popularized by Henry Ford in the early 20th Century, notably in his Ford Model T. Mass production is notable because it permits very high rates of production per worker and therefore provides very inexpensive products. Mass production is capital intensive, as it uses a high proportion of machinery in relation to workers. With fewer labor costs and a faster rate of production, capital is increased while expenditure is decreased. However the machinery that is needed to set up a mass production line is so expensive that there must be some assurance that the product is to be successful so the company can get a return on its investment. Machinery for mass production such as robots and machine presses have high installation costs. One of the descriptions Continue reading
Principles of Material Handling
Material Handling is the art of implementing movement of materials-economically and safely. In the classic sense, Material Handling is the act of creating Time and Place utility, as distinct from Manufacturing, which creates form utility. The proper application of Material Handling knowledge will result in the smooth integration of all the process in an enterprise into one efficient Production Machine. The principles presented here represent an accumulation of experience equivalent to untold years of practice. They are adapted from those stated in the literature, with certain changes made for clarification and with several new one added to round out the coverage of the field. In reviewing the principles it will be found that nearly every one applies to several aspects of Material Handling and aids in accomplishing one or more objectives. 1. Principle of Planning: All Handling activities should be planned. Description: If there is one principle on which all Continue reading
Differences Between Manufacturing and Service Operations
Generally speaking, process efficiency is the most important to manufacturing operations while production and marketing are inseparable to service operations. Manufacturing’s tangible output can be consumed overtime, less labor and more equipment are used in production, since automation has increased capital intensity while as a result reduced customer contact. Consumers rarely take part in the manufacturing process, many manufacturing operations have emphasized efficiency while compromising flexibility, the methods for monitoring and using resources are sophisticated while producing. On the other hand, service operations are different from those of manufacturing operations. Consumption and production of services takes place simultaneously or closely, and there are more labor and more customer participation, which means service businesses, usually are more customer-oriented. while elementary methods are frequently used for monitoring and using resources. To be specific, there are mainly six differences between manufacturing operations and service operations. 1. Basic organize style in operation Basically, manufacturing Continue reading
