Abstract - In this study, a technology called Value Stream
implementation process problems and advise them on success criteria to take into account and tasks to be prioritized when implementing Lean in their firms.
Mapping (VSM) is used to find and get rid of these unproductive operations, optimising the workflow in the process. Value Stream Mapping is regarded as a potent lean method for removing waste and making any organization's value stream lean and responsive. It is used to chart the flow of labour, resources, and information necessary to organise the tasks carried out by all project participants in order to deliver the finished product to the clients. The mapping of the present and future states is a component of VSM. The inefficiencies in the process and the inefficient, non-value-adding actions are revealed by mapping the existing state.
Framework for the selection of lean construction tools based on lean aims and functionality was the subject of research by Mughees Aslam et al. in 2020. Lean construction is regarded as a viable project management methodology to handle challenges in the construction sector and resolve some productivity and waste issues. Various lean tools have been developed to make the adoption of Lean Construction easier. Currently, the first choice of lean tools is mostly made based on objectives, with little thought given to how well it conforms to the building technique. This study intends to clarify constructors' first selection phase decision-making processes by shedding light on their mental models. Each Lean tool's goals and capabilities are listed in the study. The findings show that many tools have objectives that are practically identical but have distinct functionality. As a result, the selection criteria must take into account the functionalities of the lean tools. For the successful implementation of LC, the features of lean tools must be compatible with the relevant building processes. In the study, a framework for choosing the best lean tools was put forth. The main benefit of this study is that it will help constructors make better decisions when choosing the tool that would function best with their construction.

1. INTRODUCTION A literature review is a crucial component of every endeavor. It must be done in order to comprehend different project facets and will aid in the project's successful conclusion. This chapter considers and reviews research that has been done in the fields of Lean construction, workflow in construction, and value stream mapping. Research on a Lean Implementation Success Model for the Construction Industry was conducted by Sevilay Demirkesen et al. in 2020. This study's main goal is to put out a thorough success model for Lean implementation in the construction sector. A list of success criteria is defined within this framework, and these criteria are categorized into seven groups: financial, managerial, technological, workforce, cultural, governmental, and communication. When the relevance weights of these attributes have been determined by the five-person expert team, an analytical network process (ANP) model is then created to identify the connections between the success-related attributes. Eight seasoned civil engineers completed a two-part questionnaire to provide the information needed for the ANP model. The key success criteria for Lean implementation were determined to be market share, access to Lean tools and practices, and lean training. The study is anticipated to assist Lean practitioners and engineering managers in overcoming

Research on multi-objective optimization of batch and pull production for lean-based repeated scheduling was conducted by Dina A. Saad et al. in 2021. According to the study, repetitive scheduling using traditional approaches has a number of issues because of imposed resource continuity assumptions that add time and money. As a result of the unit's downtime in between tasks, it also results in a higher inventory of units with work in progress. In order to decrease Work in Progress, time, and cost, this research established a new batch- and pull-based repetitive scheduling technique that is lean-driven. It contains a builtin multi-objective optimization algorithm to choose the right number of crews and batches to use in order to cut down on time and expenses while taking resource and unit idleness
