How to Reduce Manufacturing Waste
In the latter decades of the 20th century, the creation of new lean production methods set the standard for process improvement and created the framework for the Lean Manufacturing movement. By increasing value and reducing the amount of work required to perform tasks, many companies experienced a transformation that allowed them to significantly improve competitiveness within their industries.
A core principle in lean methodology is the removal of waste within an operation. And in any business, one of the heaviest drains on profitability is waste. Lean waste can come in the form of time, material, and labor. But it may also be related to the utilization of skill-sets as well as poor planning. In lean manufacturing, waste is any expense or effort that is expended but which does not transform raw materials into an item the customer is willing to pay for.
By optimizing process steps and eliminating waste, only true value is added at each phase of production. Today, the Lean Manufacturing model recognizes 8 types of waste within an operation; seven originally conceived when the Toyota Production System was first conceived, and an eighth added when lean methodology was adopted within the Western World. Defects impact time, money, resources and customer satisfaction.
Examples of Defects within a manufacturing environment include lack of proper documentation or standards, large variances in inventory, poor design and related design documentation changes and an overall lack of proper quality control throughout the process workflow. Formalized document control and design change documentation, thorough and documented quality methods in all production phases and checklists that have been audited to ensure proper adherence to the BOM are effective ways to control defect waste.
And standardized work at each production cell or point in the production line will help reduce this type of waste as well. Excess processing is a sign of a poorly designed process. This could be related to management or administrative issues such as lack of communication, duplication of data, overlapping areas of authority and human error. It may also be the result of equipment design, inadequate job station tooling or facility layout. Process mapping is a lean waste elimination tool that helps define an optimized workflow that can eliminate over processing.
As a key method within lean production, process mapping is not limited to the performance of production tasks. It also includes reporting, signoff and document control. When components are produced before they are required by the next downstream process, overproduction occurs.
This has several negative effects. And it can hide defect s that could have been caught with less scrap if processes were balanced to allow detection earlier as earlier use of the WIP components would have revealed the defect in time to correct the issue. Takt time is used to balance production rates between cells or departments. Measured and process-mapped jobs result in reduced setup time allowing efficient small batch flow. Waiting can include people, material equipment prior runs not finished or idle equipment mechanical downtime or excess changeover time.
All waiting costs a company has in terms of direct labor dollars and additional overhead costs can be incurred in terms of overtime, expediting costs and parts. In many ways, waiting is the opposite of overproduction.
However, it can be mitigated or eliminated with many of the same remedies. Waiting is often the result of poor process design and can be addressed through proper measurement of takt time and the creation of standard work.
Inventory is considered a form of waste because of the related holding costs. This is true of raw materials, WIP and finished goods. Over purchasing or poor forecasting and planning can lead to inventory waste. Purchasing, scheduling and forecasting can have a version of standardized work in the form of defined minimums and maximums and order points that are mapped to the process flow and takt time. Common causes of Inventory Waste include:.
Poor plant design can cause waste in transportation. It can also trigger other wastes such as waiting or motion and impact overhead costs such as higher fuel and energy costs and higher overhead labor in the form of lift drivers as well as adding wear and tear on equipment.
It may also result from poorly designed processes or processes that have not been changed or updated as often as required. Value stream mapping and partial or full changes in factory layout can reduce transportation waste. This is a full documentation of all aspects of the production flow and not just the mapping of a specific production process.
This results in changes to reduce or eliminate transportation waste. Motion costs money. This not only includes raw materials but also people and equipment. It may also include excess physical motion such as reaching, lifting and bending. All unnecessary motion results in non-value-added time and increases cost.
Again, referencing core Lean Manufacturing methodology, process mapping should include facility layout and optimized workplace design that includes analysis of the distance of motion within the space as well as the location of parts, supplies and tools within the space as well.
As an effective process map is developed, proper utilization of the space can be captured with well designed and documented standard work. The eighth waste is the only lean manufacturing waste that is not manufacturing-process specific. This waste was added to allow organizations to include the development of staff into the lean ecosystem. As a waste, it may result in assigning employees the wrong tasks or tasks for which they were never properly trained.
It may also be the result of poor management of communication. By engaging employees and incorporating their ideas, providing training and growth opportunities and involving them in the creation of process improvements that reflect the reality they experience and the skills they possess, overall operational effectiveness is improved.
The elimination of this type of waste can improve all others. Cloud computing, deep analytics and machine learning work in conjunction with devices, sensors and software adaptors to connect a factory and allow it to leverage hidden capacity for improved efficiency. With a fully connected manufacturing operation, this suite of integrated technologies operates with the same value goals as do the core principles of Lean Production methodology.
And with this integrated, smart factory those values are baked in digitally, allowing Lean Manufacturing production systems to reach for even greater heights.

Some types of commonly observed wastes in manufacturing facilities include waste from overproduction, defects, inventory, unnecessary motion and transportation, waiting times, over-processing, and unused time and creativity of employees. Here are 8 ways to reduce manufacturing waste:.
Сьюзан, я люблю .
Я не могу этого сделать. - Скрестив на груди руки, он вышел из ее кабинета. Мидж горящими глазами смотрела ему вслед.
Я должен был сейчас отдыхать в Смоуки-Маунтинс. Он вздохнул и задал единственный вопрос, который пришел ему в голову; - Как выглядит эта девушка. - Era un punqui, - ответила Росио.
Пьер Клушар спал глубоким сном и не видел склонившегося над ним человека. Игла похищенного у медсестры шприца блеснула в темноте и погрузилась в вену чуть выше запястья Клушара. Шприц был наполнен тридцатью кубиками моющего средства, взятого с тележки уборщицы. Сильный палец нажал на плунжер, вытолкнув синеватую жидкость в старческую вену.
Клушар проснулся лишь на несколько секунд.
Но невозмутимость Стратмора, очевидно, подверглась тяжкому испытанию. - Кто тебе это сказал? - спросил он, и в его голосе впервые послышались металлические нотки. - Прочитал, - сказал Хейл самодовольно, стараясь извлечь как можно больше выгоды из этой ситуации. - В одном из ваших мозговых штурмов. - Это невозможно. Я никогда не распечатываю свои мозговые штурмы. - Я знаю.
Забудьте про пленку, - сказал Бринкерхофф. - Вводите ключ и кончайте со всем. Джабба вздохнул. На сей раз голос его прозвучал с несвойственным ему спокойствием: - Директор, если мы введем неверный ключ… - Верно, - прервала его Сьюзан. - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов.
Таким он его еще никогда не. Фонтейн, которого он знал, был внимателен к мелочам и требовал самой полной информации. Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались.
Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения. Он не чувствовал никакой боли - один лишь страх. Пуля ударила в кафельную плитку азульехо чуть сзади. Осколки посыпались вниз и попали ему в шею.
Беккер когда-то сам заблудился в его узких проходах. Набирая скорость на последнем отрезке Матеус-Гаго, он увидел впереди горой вздымающийся готический собор XI века.
Он дышал. Он остался в живых. Это было настоящее чудо. Священник готовился начать молитву.
Чтобы ключ никто не нашел, Танкадо проделал то же самое с Цифровой крепостью. Он спрятал свой ключ, зашифровав его формулой, содержащейся в этом ключе. - А что за файл в ТРАНСТЕКСТЕ? - спросила Сьюзан.
- Я, как и все прочие, скачал его с сайта Танкадо в Интернете. АНБ является счастливым обладателем алгоритма Цифровой крепости, просто мы не в состоянии его открыть. Сьюзан не могла не восхититься умом Танкадо.
Не открыв своего алгоритма, он доказал АНБ, что тот не поддается дешифровке.
Они двигались уже не по узкому боковому притоку, а по главному руслу. Когда улица сделала поворот, Беккер вдруг увидел прямо перед собой собор и вздымающуюся ввысь Гиральду. Звон колоколов оглушал, эхо многократно отражалось от высоких стен, окружающих площадь.
