Cellular Manufacturing
Cellular manufacturing is a process of manufacturing which is a subsection of just-in-time manufacturing and lean manufacturing encompassing group technology. The goal of cellular manufacturing is to move as quickly as possible, make a wide variety of similar products, while making as little waste as possible. Cellular manufacturing involves the use of multiple "cells" in an assembly line fashion. Each of these cells is composed of one or multiple different machines which accomplish a certain task. The product moves from one cell to the next, each station completing part of the manufacturing process. Often the cells are arranged in a "U-shape" design because this allows for the overseer to move less and have the ability to more readily watch over the entire process. One of the biggest advantages of cellular manufacturing is the amount of flexibility that it has. Since most of the machines are automatic, simple changes can be made very rapidly. This allows for a variety of scaling f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Just-in-time Manufacturing
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 In Western usage, the ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cross-training (business)
Cross-training in business operations, also known as multiskilling, involves training employees for flexible response to changing production schedules. Cross-training has been closely linked to cellular manufacturing—for example, in a book segment, "Cross Training in Cells and Flow Lines." That linkage is more thoroughly discussed in a book by Suri, which includes the benefits of posting in the work place a training matrix: Each employee in the area is listed as a row on the matrix, with various skills as columns. As an employee masters a skill, a check mark is entered in the matrix. Having multiple check marks becomes a visual source of recognition and pride by the employee. Sometimes, as an enabler of cross-training, the company adopts (perhaps as an element of a contract with the labor union) skill-base pay, which refers to a pay-for-skills incentive; for example, for each new skill mastered, the employee's wage rate is increased by some amount, such as $0.50 per hour.

Sick Leave
Sick leave (or paid sick days or sick pay) is paid time off from work that workers can use to stay home to address their health needs without losing pay. It differs from paid vacation time or time off work to deal with personal matters, because sick leave is intended for health-related purposes. Sick leave can include a mental health day and taking time away from work to go to a scheduled doctor's appointment. Some policies also allow paid sick time to be used to care for sick family members, or to address health and safety needs related to domestic violence or sexual assault. Menstrual leave is another type of time off work for a health-related reason, but it is not always paid. In most nations, some or all employers are required to pay their employees for some time away from work when they are ill. Most European, many Latin American, a few African and a few Asian countries have legal requirements for paid sick leave for employees. In nations without laws mandating paid sick leav ...

Employee
Employment is a relationship between two parties regulating the provision of paid labour services. Usually based on a contract, one party, the employer, which might be a corporation, a not-for-profit organization, a co-operative, or any other entity, pays the other, the employee, in return for carrying out assigned work. Employees work in return for wages, which can be paid on the basis of an hourly rate, by piecework or an annual salary, depending on the type of work an employee does, the prevailing conditions of the sector and the bargaining power between the parties. Employees in some sectors may receive gratuities, bonus payments or stock options. In some types of employment, employees may receive benefits in addition to payment. Benefits may include health insurance, housing, disability insurance. Employment is typically governed by employment laws, organisation or legal contracts.

Inventory
Inventory (American English) or stock (British English) refers to the goods and materials that a business holds for the ultimate goal of resale, production or utilisation. Inventory management is a discipline primarily about specifying the shape and placement of stocked goods. It is required at different locations within a facility or within many locations of a supply network to precede the regular and planned course of production and stock of materials. The concept of inventory, stock or work in process (or work in progress) has been extended from manufacturing systems to service businesses and projects, by generalizing the definition to be "all work within the process of production—all work that is or has occurred prior to the completion of production". In the context of a manufacturing production system, inventory refers to all work that has occurred—raw materials, partially finished products, finished products prior to sale and departure from the manufacturing system.

Production Flow Analysis
In operations management and industrial engineering, production flow analysis refers to methods which share the following characteristics: # Classification of machines # Technological cycles information control # Generating a binary product-machines matrix (1 if a given product requires processing in a given machine, 0 otherwise) Methods differ on how they group together machines with products. These play an important role in designing manufacturing cells Cellular manufacturing is a process of manufacturing which is a subsection of just-in-time manufacturing and lean manufacturing encompassing group technology.

Takt Time
Takt time, or simply Takt, is a manufacturing term to describe the required product assembly duration that is needed to match the demand. Often confused with Cycle time (software), cycle time, takt time is a tool used to design work and it measures the average time interval between the start of production of one unit and the start of production of the next unit when items are produced sequentially. For calculations, it is the time to produce parts divided by the number of parts demanded in that time interval. The takt time is based on customer demand; if a process or a production line are unable to produce at takt time, either demand leveling, additional resources, or process re-engineering is needed to ensure on-time delivery. For example, if the customer demand is 10 units per week, then, given a 40-hour workweek and steady flow through the production line, the average duration between production starts should be 4 hours, ideally. This interval is further reduced to account for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

No Value Added
No value added (NVA) is a management term loosely related to the lean manufacturing movement as codified in the 1980s by a landmark MIT study of the automobile industry, which explained lean production for the first time. No Value Added programs can be formal or whimsical. Generally, they involved seeking input and opinion from every level of the organization about rules, processes or process elements which are said to be "no value added". In one form, the proponent of an activity accused of being NVA must defend it, or suspend it. In a milder form, the proponent (or process owner) of an activity accused of being NVA is simply informed that it is seen in that light. Oddly, this milder form is often effective because in a large organization, the original reason for an activity can be long forgotten, similar to ''cabooses'' which came into use in the 1830s, but eventually had no useful purpose and became NVA. Some claim that this NVA is a jibe at ''Net Value Added'' accounting metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
