Implementando a Lógica de Produção Puxada: Uma Pesquisa-Ação

ABSTRACT Context: there is little empirical evidence of the relationship between the implementation of lean techniques (such as the pull system) and their real effect on supply chain performance. Objective: the purpose of this paper is to describe the process of implementing the pull production logic in the supply chain, reporting the historical evolution of indicators, such as inventory levels and lead times over 23 months of intervention. Methods: an action research project was carried out describing chain intervention steps in 2017-2019, divided into phases as follows: planning, data collection, implementation of the action, analysis and evaluation of the results. Results: the main contribution was to demonstrate that the production shift from push to pull had a positive impact on lead time, inventory, and planning routines indicators. Inventory levels were reduced by more than 30% and lead times were down approximately 40%. In addition, sales forecast assertiveness increased. Conclusion: this paper may provide a reference for organizations that want to make similar changes in their supply chains and significantly change the planning routine of their suppliers and distributors by implementing the pull logic.

Lean Construction Technique

Lean construction is as an effective management tool to enhance the productivity in construction field. Large research is being done in recent past and is an on-going process to adopt lean principles from manufacturing industry to the construction industry. In order to improve the efficiency, reduction of waste, the lean construction has been introduced as new management tool. There are many challenges in implementing the lean concept in construction industry in India. Due to lack of attention and illiteracy towards the lean management principle, stake holders associated to this like builder, contractor, and engineering and project management firms etc. are still in process of adopting this principle for construction project. In this project report efforts are made to find out main barriers towards the implementation of lean techniques in Indian construction industry with the help of questionnaire survey and actual site implementations are made to develop a process map for on-going projects. Results of the survey showed that some of the lean techniques should be given more focus to enhance the process. The framework results show that the NVA (Non Value Added) and ENVA (Essential Non Value Added) activities have the highest impact on the project duration. Therefore with implementation of the proposed lean techniques, the NVA and ENVA activities have found to be improved and their durations can be reduced considerably.

This work aims to improve cost reduction, standardization, and assembly cycle time optimization of a packaging machine using lean techniques. Amongst various tools of lean manufacturing techniques like waste elimination, standardized work approach, visual management, etc., are used. Among the eight types of waste, waste related to the packaging machine like incorrect processing, waiting, and unused employee creativity were identified and reduced. Kaizen is done for value engineering purposes. The work instruction manual is created to avoid the waste of incorrect processing and optimize the machine’s cycle time.

Improving internal logistics of a bus manufacturing using the lean techniques

PurposeThis study aims to improve the reception and positioning of materials in the warehouse, as well as the internal logistics of a bus manufacturing company by acting upon the processes of supply line management.Design/methodology/approachThis study is based on the action research methodology which, through a practical approach, intends to generate transferrable knowledge to other organizations whose situations are similar to that of this study. The practical actions and the knowledge acquired co-create the changes needed for the improvement processes.FindingsThrough these improvements, it is possible to standardize supply and eliminate the retention of picking carts on the line, simplify the management of materials provided in supermarket boxes, improve the control of materials and facilitate the process of picking and materials storage. A kanban card-based supply system was also expanded to the bus assembly line, allowing more control over valuable materials.Originality/valueThis study has demonstrated how the implementation of lean techniques on a bus assembly line can lead to increased consistency of supply to the line and improved working conditions, both in the production and warehouse areas. Furthermore, it has set a new standard of the internal logistics processes and the inclusion of process recording in the working instructions.

Lean Manufacturing Towards Sustainability

This paper intends to capture the attention of the lean researchers towards a shift of priorities of the various techniques implemented in lean and its journey of 40 years in the global scenario. In particular, the paper focuses on the implementation of lean techniques in India under the banner of sustainability. The paper focuses on three industries, a textile industry representing industrial revolution 1.0, an automotive spare parts industry representing industrial revolution 2.0, and an electrical/electronics industry representing industrial revolution 3.0, named ‘A', ‘B', and ‘C', respectively, and analyses the priorities of the eight best techniques of lean in the sustainability phase. The techniques are Kaizen, Poke-Yoke, 5S, Kanban, Just-in-Time, Jidoka, Takt-Time, and Heijunka. The industries ‘A' and ‘C' have Poke-Yoke as the most critical technique and have been ranked one whereas in industry ‘B' 5S emerges as the most prolific technique in the Indian context of these industries.

Enhancement of Production Rate and Flexibility in an Assembly Line by Execution of Various Lean Techniques - A Case Study

This research work mainly focuses on the flexibility and productivity improvement through the execution of different lean techniques in the valve assembly of medium scale manufacturing unit. The different types of wastes percentage are determined to find out the waste which mainly affects the productivity. The major wastes of motion waste by about 30% and unwanted distance of 250 square foot were reduced by implementation of kaizen in the valve assembly area. Value stream mapping was used to identify the bottleneck process and by eliminating the bottleneck process results in the reduction of excess motion and non-value added activity by 45%. Work-in-process aging and work-in-process inventory cost was calculated and the production level was estimated by using 95th Percentile calculation. The total lead time was reduced about 54minutes with reduction of transportation time 2.7minutes after the implementation of lean techniques and the productivity of the valve assembly was also increased to about 6% after reducing the non-value added activities.

Lean readiness assessment model – a tool for Humanitarian Organizations' social and economic sustainability

Purposepurpose of this study is to present a Lean Readiness Assessment Model (LRAM) for assessing the readiness of Humanitarian Organizations (HO) for adopting Lean Management (LM) (Johanson et al.) practices. Literature reveals that implementation of LM itself is a cost and most organizations have failed to adopt LM techniques due to a non-readiness status and a non-supportive organizational culture. This situation indicates that the assessment of organizations' readiness before implementation of lean techniques is necessary.Design/methodology/approachThis was an empirical quantitative study. Based on a synthesis of the literature, a conceptual model was developed by identifying seven critical success factors (CSFs). The CSFs were validated by HO professionals via a questionnaire-based survey. The data from the responses were analysed by applying partial least square structured equation modelling (PLS-SEM) using the SmartPLS3 software.FindingsA proven LRAM was constructed that consists of CSFs (independent and mediating variables), which have reflected positive coefficients and significant t >1.96 and p < 0.05 values. The CSFs that are significant include process management, planning and control management, customer relationship management, human resource management, communication and coordination management and a positive organizational culture. The CSFs of supplier relationship and top management and leadership had insignificant t and p values and were dropped from the final LRAM.Originality/valueThis is a unique and rare study in its nature which developed LRAM for HO sector. The contribution of this model is to improve the efficiency and sustainability (economic and social aspects) of an HO under scarce resource conditions.

Application of Lean Principles in Five-Star Hotels in Egypt

The hospitality industry faces the challenge to decrease or eliminate their costs and to be more efficient in the near future. In recent years, the hospitality industry showed growth continuously, applicability to implement Lean in the hospitality and tourism sectors to improve productivity and service quality. Nevertheless, the literature review highlighted there are little hotels and tourism organization implemented Lean in their operation. Reason for that, Lean technique used in a single department of the establishments, which lead to missing the overall approach of Lean. Globally, the implementation of Lean techniques has proven to be successful in improving quality while reducing turnaround times and costs within the hospitality industry. There appears to be limited publicly available current research regarding Lean implementation in Egyptian hotels, leading to the motivation for this study. Therefore, the aim of this paper is to identify the application of Lean principles in Cairo five-star hotels in Egypt. This research adopted a quantitative approach to achieve the aim, objectives. A questionnaire was used for data collection. 72.5% was the average response rate. Statistical Package for Social Sciences (SPSS, version 16) program was used for analysing data. The results indicated that awareness and knowledge of the hotel participants about Lean term not clear for them and they did not know its meaning. The results showed that hotels did not implement Lean principles in their operations. A major contribution of this research is related to enhance the understanding of Lean principles. This research added to the growing Lean principles literature through its review of the previous academic research, generation of new ideas and interpretation of rich data collected from the different sources.
