Lean production not only successfully challenged the accepted mass production practices in the automotive industry, significantly shifting the trade-off between productivity and quality, but it also led to a rethinking of a wide range of manufacturing and service operations beyond the high-volume repetitive manufacturing environment. Holweg, Toyota production system was initially introduced by Japan after World War II when Japan required producing small batches of cars in many varieties in contrary to the Ford principle of mass production same cars with large production runs Conte Toyota concluded that the principle of mass Production is not efficient anymore, especially, after the collapse in sales that Toyota encountered and led to releasing large part of their workforce. This research work is regarding the problems facing by the construction industry in Gujarat, where India is the second fastest growing economy in the world.

Lean construction as a panacea for poor construction projects performance

Lean tools got their start in America as early as the s, when Henry Ford used Lean methodology to create the Model T assembly line. Lean methodology also has an expansive legacy outside the U. In addition to being the first to correctly implement the Lean tool Just-In-Time, for example, Toyota is also known for creating its own Lean Production System. Lean tools are utilized across many industries—from manufacturing to engineering to finance— and organizations often leverage them together with Six Sigma methods. Though there are some differences between the two frameworks, the underlying philosophies behind Lean and Six Sigma complement each other exceptionally well: Lean tools are designed to eliminate invaluable processes, while Six Sigma focuses on lessening variation within a process. When used together, the two are referred to as Lean Six Sigma, a process that reduces and manages different types of waste in organizations. Though there are several different types of Lean tools, this article will focus on seven of them, and how they can be applied.

Lean work structuring is process design integrated with product design and extends in scope from an entire production system down to the operations performed.

Lean Construction Technique: Why it Matters

Lean construction is a combination of operational research and practical development in design and construction with an adaption of lean manufacturing principles and practices to the end-to-end design and construction process. Unlike manufacturing, construction is a project-based production process. Lean Construction is concerned with the alignment and holistic pursuit of concurrent and continuous improvements in all dimensions of the built and natural environment: design, construction, activation, maintenance, salvaging, and recycling Abdelhamid , Abdelhamid et al. This approach tries to manage and improve construction processes with minimum cost and maximum value by considering customer needs Koskela et al.

An Introduction to Lean Construction

The purpose of this study is to ascertain the extent to which the practices of small and medium building contractors SMBCs conform to lean construction LC principles. Ultimately, practical results encourage a discourse on the true potentials and challenges to the holistic uptake of LC principles in the Ghanaian construction industry. This research is based on a qualitative case study approach. The data was obtained through face-to-face structured interviews. There was no indication that lean concepts were used on a company-wide basis in the Ghanaian construction industry.

Lean construction LC is a method of production aimed at reducing costs, materials, time and effort. Essentially, the methodology is to minimize the bad and maximize the good. Using the principles of lean-construction, the desired outcome would be to maximize the value and output of a project while minimizing wasteful aspects and time delay. This outcome is produced when standard construction approaches are merged with a clear and concise understanding of project materials and information and two sets of management archetypes, planning and control. This may seem complex to understand, but the essence of this system to use what is necessary without extra. This can only be done by strategic planning and action by a management group and with the help and aid of all workers.

Recurring problems in the delivery of construction projects have been time and cost overruns, poor quality, poor health and safety, waste and loss of value. This situation is worsened by the reluctance of construction organisations to fully implement lean construction technique which has proved to be an innovative solution to these problems. A well-structure questionnaire distributed by hand and electronically using the snowball sampling technique were used to gather data from the participants from both the private and public organisations. Frequency, percentage and factor analysis were used to analyse the collected data. It was found that the level of awareness of lean construction is high but it s adoption is low. Lean construction is a panacea for poor construction project performance because of it s cost related benefits, value and relationship benefits, environmental benefits, quality improvement benefits, motivation and productivity benefits, profitability and market benefits, time and work flow benefits, waste reduction benefits, and HS and rework reduction benefits.

В нашей стране происходит много хорошего, но немало и плохого. Кто-то должен иметь возможность оценивать и отделять одно от другого. В этом и заключается наша работа. Это наш долг. Нравится нам это или нет, но демократию от анархии отделяет не очень-то прочная дверь, и АНБ ее охраняет.

Бесчувственная демонстрация силы страной, уже добившейся победы. С этим Танкадо сумел примириться. Но он не смог примириться с тем, что этот взрыв лишил его возможности познакомиться с собственной матерью.

 - Коммандер, - сказала она, - если вы инструктировали Дэвида сегодня утром по телефону из машины, кто-то мог перехватить… - Один шанс на миллион, - возразил Стратмор, стараясь ее успокоить.  - Подслушивающий должен был находиться в непосредственной близости и точно знать, что надо подслушивать.  - Он положил руку ей на плечо.  - Я никогда не послал бы туда Дэвида, если бы считал, что это связано хоть с малейшей опасностью.

Прямо. - Встретимся в Стоун-Мэнор. Она кивнула, и из ее глаз потекли слезы. - Договорились.
