Lean production aims at operational improvement by the elimination of waste and variability reduction. The lean practice known as help chain, which contributes to the lean goals is an underexplored topic.

A system dynamics SD -based methodology is described for analysing the impact of lean manufacturing strategies on a company's business performance, using business model canvas BMC perspective. A case study approach is used to describe the methodology which consists of conceptualising a SD model on the basis of BMC. The base SD model is elaborated to include variables and concepts that consider the effects of lean manufacturing metrics on business performance. In the modelling experimentation, the lean manufacturing metrics are made to take on likely values one would expect if certain lean practices are initiated or improved. The experimental results provide one with the likely impact on business performance, if one were to improve lean manufacturing practices. The simulation results for the case study show that lean improvements, on the short-run, have a significant impact on business performance, but in the long run, the impact is only marginal.
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.
The term "Lean" was coined in by John Krafcik , and defined in by James Womack and Daniel Jones to consist of five key principles: 'Precisely specify value by specific product, identify the value stream for each product, make value flow without interruptions, let customer pull value from the producer, and pursue perfection. Insights relating to value streams , efficiency reduction of "waste" , continuous improvement and standardised products can most likely be traced back to the beginning of humankind. However, Fredrick Taylor and Henry Ford documented their observations relating to these topics, and Shigeo Shingo and Taiichi Ohno applied their enhanced thoughts on the subject at Toyota in the s. American industrialists recognized the threat of cheap offshore labor to American workers during the s, and explicitly stated the goal of what is now called lean manufacturing as a countermeasure. Henry Towne, past President of the American Society of Mechanical Engineers , wrote in the Foreword to Frederick Winslow Taylor's Shop Management , "We are justly proud of the high wage rates which prevail throughout our country, and jealous of any interference with them by the products of the cheaper labor of other countries.

The goal of lean production is to save costs, produce products in various quantities, and cancel out all kinds of wastes. The lean production system, developed as an alternative to the western style production system, also takes place in the literature as an alternative application of traditional production systems. In this context, the main purpose of this study is to determine the feasibility and awareness of the lean production concept, which is widely accepted and applied in various sectors especially in developed countries, in Turkey.
- Сюрреализм. Я в плену абсурдного сна. Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца. Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо.
- Уберите ногу. Взгляд Беккера упал на пухлые пальцы мужчины.
В руке он сжимал ключ, взятый из лаборатории систем безопасности. Чатрукьян опустился на колени, вставил ключ в едва заметную скважину и повернул. Внизу что-то щелкнуло.
Он недвусмысленно гласит, что если компьютер переберет достаточное количество ключей, то есть математическая гарантия, что он найдет правильный. Безопасность шифра не в том, что нельзя найти ключ, а в том, что у большинства людей для этого нет ни времени, ни необходимого оборудования. Стратмор покачал головой: - Это шифр совершенно иного рода. - Иного рода? - Сьюзан смотрела на него вопрошающе.
