Modularity is a degree to which a system’s component maybe separated and recombined. However, it can be used in different contexts and its definition changes accordingly. For example. In Biology, it is the concept that organisms or metabolic pathways are composed of modules. In Nature, modularity refers to the construction of a cellular organism by joining together standardized units to form larger compositions. In cognitive science, the idea of modularity of mind holds that the mind is composed of independent, closed, domain-specific processing modules, etc. But here we will be concentrating on Modularity in operations management, which refers to an engineering technique that builds larger systems by combining smaller subsystems. The growing concern for the environment has spurred a great interest in environmentally aware design and manufacturing amongst designers worldwide. Introducing Modularity in consumer products can help bring multiple manufactures come together creating differentiated assembly lines that can decrease the Continue reading

Seven Basic Tools of Quality
For the reason of human factor and human reliability, it is inevitable that there could be occurred some kind of faults and errors even in well planned and technically equipped organizations and systems. The errors or unplanned risks that might be happened during the project, can lead the customer to have negative opinion about the management team. Also some faults and risks might not being able to fix or might be too expensive to overcome it. Therefore a well prepared quality management plan is essential for an organization in order to ensure that the management plan that the project team works on, meet the customer satisfaction and their needs. At this stage Ishikawa’s seven quality tools are quite helpful to determine, identify and evaluate the problems, their causes and suggestions for a continuous improvement process. These tools can be listed as; Histogram, Flow Chart, Scatter Diagram, Pareto Chart, Cause and Continue reading
Facilities Planning – Meaning and Importance
One of the major strategy decisions that must be made by any organization is where to locate its producing and storage facilities. For manufacturers, the problem is broadly categorized into factory location and warehouse location; within this categorization, we may be interested in locating the firm’s first factory or warehouse or locating a new factory or warehouse relative to the locations of existing facilities. The general objective in choosing a location is to select that site or combination of sites that minimizes two classes or costs — regional and distribution or sites that minimizes two classes or costs — regional and distribution costs. Regional costs are those associated with a given locate and include land, construction, manpower, and state and local expenses and regulations. Distribution costs are those directly related to the shipping of supplies and products to customers and other branches of the distribution network. Since the location of Continue reading
Negative Aspects of Material Handling Systems
It is bad engineering and worse management practice to look only at benefits and to ignore limitations. Handling systems, at times, have consequences that may be distinctly negative. These too, should be evaluated before the changes are adopted. Some such possible disadvantages are 1) Additional capital investment: It must be verified that the cost of the handling system is more attractively invested in the system under consideration than in any other part of the business. It should be assured that the gains expected are not based upon a more mechanized system v/s present practice, but rather the proposed new system v/s the best version of present practice. 2) Loss of flexibility Proposed system must be flexible enough to be economically and quickly adapted to the likely range of changes in the product or production techniques. If not, change over cost and time loss must be included in the evaluation, or Continue reading
Introduction to Production Management
Meaning Of Production Management A few definitions of production management are being reproduced here under to understand the meaning of the term clearly: “Production management is the process of effectively planning and regulating the operations of that part of an enterprise which is responsible for actual transformation of materials into finished products”. Elwood S. Buffa has defined the term in a broader sense as: “Production management deals with decision making related to production process so that the resulting goods or services are produced according to specifications, in amounts and by the schedules demanded and at a minimum cost”. Production management, thus, is assigned with the following tasks. Specifying and accumulating the input resources, i.e., management, men, information, materials, machine and capital. Designing and installing the assembling or conversion process to transform the inputs into output, and Coordinating and operating the production process so that the desired goods and services may Continue reading
Factors Influencing Plant Layouts
The basic objective of any plant layout is to ensure a smooth flow of work, material, and information through a system. The basic meaning of plant is the space in which a business’s activities take place. The layout and design of that space impact greatly how the work is done-the flow of work, materials, and information through the system. The key to good plant layout and design is the integration of the needs of people (personnel and customers), materials (raw, finishes, and in process), and machinery in such a way that they create a single, well-functioning system. Recommended reading: Plant layouts – Definition and Objectives The following are some important factors, which influence the planning of effective layout to a significant degree. 1. Nature of the product: The nature of the product to be manufactured will significantly affect the layout of the plant. Stationary layout will be most suitable for Continue reading
