Lean construction researchers and practitioners have established a new paradigm for managing construction projects. This paradigm stems from insights gained by viewing project delivery as one kind of production and, inspired by the success of the Toyota Production System, leveraging Toyota's 'lean thinking' in the context of such one-of production. Premises of lean construction are that (1) production systems are riddled with variation, (2) variation can be good or bad, but most of it is bad, (3) most of this variation-good or bad-is self-inflicted; consequently 'lean' passionately promotes good- and relentlessly eradicates bad variation. This paper surveys a few of many lean construction means to manage variation. Lean thinking encompasses a lot more than thinking about variation, but that is the lens used here through which construction project management is viewed. Pairing these premises with lean variation-management tools may help readers broaden the insights they can gain from reading the lean construction literature.

Since Lean Construction has been introduced as a new management approach to improve productivity in the construction industry, much research is in progress to develop lean concepts and principles for better implementation and to get results of the successful adaptation of lean ideas from manufacturing for application in the construction industry. Currently, several construction companies in the USA are starting to implement lean construction with nebulous hopes of obtaining better results from their current projects than from past projects not employing lean construction. There are many difficulties in adopting lean concepts and systems into construction projects and implementing lean construction in real construction sites. Thus, there are demands to share information how other companies implement lean construction, to identify the benefits and barriers of lean implementation in the construction fields, and finally to improve their lean implementation. This study was the first exploratory study to assess lean construction implementation on overall projects. The case studies carried out the examination of the mutual relationships of lean planning systems, organization structure, attitudes of project participants and company strategy which played major influences on successful lean implementation

Successfully adapting to digital and customer-oriented transformation, the concept of lean manufacturing professes the philosophy of creating greater benefit while minimizing losses. These losses are operations that do not add value in the production process to ensure the efficiency, flexibility, and profitability of projects. In the context of broad automation and digitalization of all sectors of the economy, mechanisms for combining automation technologies and lean production are becoming available. Moreover, when it comes to the efficient use of financial, human, or material resources, it is clear that the use of Industry 4.0 technologies can be an effective tool for achieving the goals of lean production, as many of them pursue the same goal. In this context, this article aims to study the effectiveness of the implementation of project management concepts at the global level and identify the main factors influencing its effectiveness to ensure the achievement of lean production through LEAN technologies and Industry 4.0 technologies. To achieve this goal, several statistical indicators were selected and several statistical methods of analysis were used: pairwise correlation, regression analysis, methods of comparison, synthesis, and generalization. Statistical analysis was conducted according to a survey conducted by the Project Management Institute (PMI) in 2020. An economic-mathematical model of dependence of project effectiveness in different regions of the world on the level of implementation of project management approaches is built, which shows that the increase in project effectiveness by 85% is due to financial losses, technical training, and consumer orientation. These results allow project managers to develop appropriate strategies to improve project management approaches at all levels. It is established that LEAN technologies and technologies of Industry 4.0 have several tools that have a positive effect on minimizing losses following the concept of lean production. Besides, given that the technology of Industry 4.0 is focused on the automation of Lean Production technology, a mechanism for the introduction of lean production using these technologies and methods.

To maximize the operational efficiency of production and operations systems, Six Sigma and Lean Production System have been widely used. The main focus of Six Sigma is reducing variations, whereas that of Lean Production System is eliminating losses. To take advantage of the two approaches Six Sigma and Lean Production System was integrated into Lean Six Sigma, and the integrated approach has been used in recent years. In the implementation of Lean Six Sigma, the problems under consideration have often physical or technical contradictions which are difficult to be solved by conventional methods. To solve such contradictions TRIZ is useful in many cases. In this thesis, it is considered that how TRIZ can be applied to Lean Six Sigma. An integrated road-map of Lean Six Sigma and TRIZ is suggested and some cases are reviewed.

린 건설이 소개되어진 이후 많은 린 건설 관련 연구들이 진행되어지고 있다. 하지만 기존의 연구들은 린 건설 개념과 기법 개발에 중점을 두고, 기계적 합리성과 기술적 효율성만을 향상시키는데 그 초점을 맞추고 있으며, 린 건설의 인적 자원 측면에서의 연구는 거의 이루어지지 않고 있다. 따라서 도입 초기 단계인 국내의 린 건설의 활성화와 보급화를 위해서는 한번쯤 이러한 연구가 이루어져야 할 것으로 생각된다. 왜냐하면 린 건설 도입 초기 단계에 있어서 린 건설에 필요한 많은 기능들을 수행하고 이의 잠재성을 성공적으로 이끌어내기 위해서는 참여 건설 인력의 잠재성과 능력에 상당 부분 의존할 수 발 에 없기 때문이다. 본 연구에서는 국내 현장 조사에 앞서 미국 내 린 건설을 적용하고 있는 건설 현장의 원도급자와 하도업자를 포함한 작업 인력들에 대해 설문조사 및 인터뷰를 통해 린 건설이 인적자원과 어떠한 관련이 있으며 어떤 효과를 제공할 수 있는 지에 관하여 분석하고자 한다. 본 연구의 결과는 린 건설이 건설 현장에서 적절히 도입되고 수행되어질 경우 인적 자원의 능력 향상 및 작업 동기 유발에 큰 도움이 될 수 있음을 보여준다. 린 건설은 무엇보다도 공사 참여자들 간의 관계 개선에 중점을 두고 있기 때문에 린 건설을 수행하는데 있어서 인적자원과의 연관성을 잊어서는 안 될 것이다.

Purpose - This paper explores the contribution lean makes to service levels by addressing lean thinking application in logistics process improvement within a MNC soft drinks manufacturer situated in the United Arab Emirates, and identifies the most significant sources of wastes and their interdependence and highlights key attributes of successful lean implementation. Research design, data, and methodology - This case study examines key logistics employees' perceptions on lean methodology. Results - The results highlight the most significant types of wastes in logistical processes and illustrates ways to eliminate wastes and streamline process flow. The importance of the human role within lean methodology is also identified. Findings suggest that managers should follow both a micro and macro approach when implementing lean practices, as focusing on one waste often leads to ignoring the significance of other wastes. Conclusions - This study highlights the importance of implementing lean at both micro and macro levels and shows how staff involvement increases the efficacy of lean thinking. It offers guidance towards the efficiency of creating value stream mapping processes in situ, which considers different wastes and their interdependence. Managers with limited resources are encouraged to implement lean methodology taking cognizance of these factors.
