Just-in-time or JIT means producing goods and services exactly when they are needed, like for example a new company opens that is producing steering shaft for automobiles. The company, under the JIT system, will set up the machines to produce the jobs in a row from those who collect the metals at one end, all of the way to those who ship the product at the other end of the factory. The people at each station, as they receive the product, take the job order, perform their duties on the product, and then transfer the product out to the next station after their work is completed. Along the way, the product is screened for infirmities, and if they exist, the line is stopped until the defect is repaired. In the end, the shipping agent will receive the product and ship it to the customer. All along Continue reading
Operations Management Techniques
Criteria for a Good Layout
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
Lean Supply Chain Management
Even though Toyota – the Japanese company – was the one who made the lean concept widely well-known with the Toyota production system (TPS), there is a fact shows that lean did not just emerging but it was partially used in the United States. For example in 1908, “Scientific management” made by Frederick W. Taylor was the concept of using scientific method such as standardization to apply with the working process. This scientific idea was criticized to be the initial stage of developing the lean concept, since it helped workers to work in system and ignored the unnecessary jobs. However, Henry Ford is considered to be the first person, who used the lean principles. In 1910, Ford has developed the concept of continuous flow – called Ford’s model T production system (MTPS) – for manufacturing assembly line. This MTPS was to have workers focusing on their individual jobs and moving 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
Just-in-Time (JIT) Production Technology
In today’s competitive global business environment, the goal of all manufacturing systems is long-term survival. A manufacturing company’s survival in an increasingly competitive market closely depends upon its ability to produce highest quality product at lowest possible cost and in a timely manner with shortest possible lead-time. In addition, these goals should be achieved by paying utmost respect to the humanity of the employees who make the system work. Sometime, the difficulty of achieving the goals lies in the complexity of manufacturing operations. It is not difficult to build the high quality product, but is extremely difficult to do so while maintaining excellent quality, and at some time respecting the humanity of people who do the actual work of building that product. A Just-in-Time (JIT) based approach, which is suggested here, is capable of achieving all above stated goals. Just-in-Time (JIT) Based Quality Management is both philosophy and guiding set Continue reading
Improvements In Productive Flow And Product Quality
The main objective of any business is profit making which it derives by making its products and services available to people. The business models therefore, can be described as value propositions for various stakeholders for which the management evolves strategies and methodologies to create goods and services in some particular arena and delivers the same to the desired target group or customers. It explains how the business would function, identify the goods and services that would be produced for identified customers, ensure the viability of the objectives and goals of the business to deliver values based services. In the contemporary environment of highly competitive business, innovative managerial practices become critical for increasing profitability without major capital investment. The essay would therefore focus on how the improvements in productive flow and product quality would impact on firms’ sales and profit. Productive Flow and Quality Product Productive flow broadly defines the streamlined Continue reading
