Continuous-flow Manufacturing
Continuous-flow manufacturing, or repetitive-flow manufacturing, is an approach to discrete manufacturing that contrasts with batch production. It is associated with a just-in-time and kanban production approach, and calls for an ongoing examination and improvement efforts which ultimately requires integration of all elements of the production system. The goal is an optimally balanced production line with little waste, the lowest possible cost, on-time and defect-free production. This strategy is typically applied in discrete manufacturing as an attempt to handle production volumes comprising discrete units of product in a flow which is more naturally found in process manufacturing. The basic fact is that in most cases, discrete units of a solid product cannot be handled in the same way as continuous quantities of liquid, gas or powder. Discrete manufacturing is more likely to be performed in batches of product units that are routed from process to process in the factory. Ea ...

Discrete Manufacturing
Discrete manufacturing is the production of distinct items. Automobiles, furniture, toys, smartphones, and aeroplanes are examples of discrete manufacturing products. The resulting products are easily identifiable and differ greatly from process manufacturing where the products are undifferentiated, for example oil, natural gas and salt. Discrete manufacturing is often characterized by individual or separate unit production. Units can be produced in low volume with very high complexity or high volumes of low complexity. Low volume/high complexity production results in the need for a flexible manufacturing system that can improve quality and time-to-market speed while cost cutting, cutting costs. High volume/low complexity production puts high premiums on inventory controls, lead times and reducing or limiting material costs, materials costs and waste reduction, waste.

Batch Production
Batch production is a method of manufacturing where the products are made as specified groups or amounts, within a time frame. A batch can go through a series of steps in a large manufacturing process to make the final desired product. Batch production is used for many types of manufacturing that may need smaller amounts of production at a time to ensure specific quality standards or changes in the process. This is opposed to large mass production or continuous production methods where the product or process does not need to be checked or changed as frequently or periodically. Characteristics In the manufacturing batch production process, the machines are in chronological order directly related to the manufacturing process. The batch production method is also used so any temporary changes or modifications can be made to the product if necessary during the manufacturing process. For example, if a product needed a sudden change in material or details changed, it can be done in be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Just In Time (business)
Lean manufacturing is a production method aimed primarily at reducing times within the production system as well as response times from suppliers and to customers. It is closely related to another concept called just-in-time manufacturing (JIT manufacturing in short). Just-in-time manufacturing tries to match production to demand by only supplying goods which have been ordered and focuses on efficiency, productivity (with a commitment to continuous improvement) and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow and throughput times by further eliminating activities which do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service. Lean manufacturing is particularly related to the operational model implemented in the post-war 1950s and 1960s by the Japa ...

Kanban
Kanban (Japanese: カンバン and Chinese: 看板, meaning signboard or billboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. The system takes its name from the cards that track production within a factory. Kanban is also known as the ''Toyota nameplate system'' in the automotive industry. Kanban became an effective tool to support running a production system as a whole, and an excellent way to promote improvement. Problem areas are highlighted by measuring lead time and cycle time of the full process and process steps. One of the main benefits of kanban is to establish an upper limit to work in process (commonly referred as "WIP") inventory to avoid overcapacity. Other systems with similar effect exist, for example CONWIP. A systematic study of various configurations of kanban systems, such as Generalized Kanban or ...

Process Manufacturing
Process manufacturing is a branch of manufacturing that is associated with formulas and manufacturing recipes,Difference Between Discrete and Process Manufacturing BatchMaster Blog. and can be contrasted with , which is concerned with discrete units, bills of materials and the assembly of components. Process manufacturing is also referred to as a 'process industry' which is defined as an industry, such as the chemical or petrochemical industry, that is concerned with the processing of bulk resources into other products.

Muda (Japanese Term)
is a Japanese word meaning "futility; uselessness; wastefulness", and is a key concept in lean process thinking, like the Toyota Production System (TPS) as one of the three types of deviation from optimal allocation of resources (the others being '' mura'' and '' muri''). Waste in this context refers to the wasting of time or resources rather than wasteful by-products and should not be confused with Waste reduction. From an end-customer's point of view, value-added work is any activity that produces goods or provides a service for which a customer is willing to pay; ''muda'' is any constraint or impediment that causes waste to occur. There are two types of muda: * Muda Type I: non value-adding, but necessary for end-customers. These are usually harder to eliminate because while classified as non-value adding, they may still be necessary. * Muda Type II: non value-adding and unnecessary for end-customers. These contribute to waste, incur hidden costs and should be eliminated. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Changeover
In manufacturing, changeover is the process of converting a line or machine from running one product to another. Changeover times can last from a few minutes to as much as several weeks in the case of automobile manufacturers retooling for new models. Reducing changeover times became a popular way to reduce waste in Lean manufacturing after Taiichi Ohno and Shingo Shigeo popularized the SMED (Single Minute Die Exchange) method in the, now famous, Toyota Production System (TPS). The terms ''set-up'' and ''changeover'' are sometimes used interchangeably however this usage is incorrect. Set-up is only one component of changeover. Example: A soft drink bottler may run 16oz glass bottles one day, perform a changeover on the line and then run 20oz plastic bottles the next day. The 3 Ups Changeover can be divided into the 3 Ups: Clean-up ''Clean-up product, materials and components from the line. It may range from minor, if only the label of a package is being changed (for example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Production Planning And Control
Production planning is the planning of production and manufacturing modules in a company or industry. It utilizes the resource allocation of activities of employees, materials and production capacity, in order to serve different customers.Fargher, Hugh E., and Richard A. Smith. "Method and system for production planning." U.S. Patent No. 5,586,021. 17 Dec. 1996. Different types of production methods, such as single item manufacturing, batch production, mass production, continuous production etc. have their own type of production planning. Production planning can be combined with production control into production planning and control, or it can be combined with enterprise resource planning. Overview Production planning is the future of production. It can help in efficient manufacturing or setting up of a production site by facilitating required needs. A production plan is made periodically for a specific time period, called the planning horizon. It can comprise the following ac ...
