Last planner system (LPS) has been recognized as one of the most formidable tools for implementing lean construction (LC) and improving construction productivity. The past 25 years have witnessed the sequential development of LPS but still, the construction industry is unable to utilize its full potentials. It was reported that users of LPS were only able to achieve 70% of their weekly assignments with much potential to perform better. Considering it is a complete lean construction tool, LPS is mostly implemented in isolation, thereby exposing many areas that are overlooked and poorly managed. In this study, an effort has been made in developing strategies to overcome LPS implementation challenges by integrating LPS with other available lean tools and techniques. A systematic literature review is carried out, followed by a conceptual development of findings and theories into a robust integrated LPS implementation model. Thirteen (13) major shortcomings in implementing LPS and sixteen (16) lean tools to overcome these shortcomings are identified. Presently, LPS is managed as a single entity. However, due to its vast diversity, all of its stages should be managed independently. In this study, lean tools are integrated within LPS stages to develop the innovative integrated last planner system (ILPS), allowing the management of LPS stages independently. Additionally, a guideline for sequential amalgamation of LPS with the lean tools at different stages is presented to smoothen the ILPS implementation process. The ILPS will facilitate the construction industry in utilizing LPS to its fullest potential. This newly developed ILPS will help the lean practitioners in increasing construction productivity and reducing cost and time.

开发创新的综合最后规划系统（ILPS）

最后规划系统 (LPS) 已被公认为实施精益施工 (LC) 和提高施工生产率的最强大工具之一。过去 25 年见证了 LPS 的连续发展，但建筑行业仍然无法充分发挥其潜力。据报道，LPS 的用户只能完成 70% 的每周任务，并且有很大的潜力可以做得更好。考虑到它是一个完整的精益建设工具，LPS大多是孤立实施的，从而暴露了许多被忽视和管理不善的领域。在这项研究中，通过将 LPS 与其他可用的精益工具和技术集成，努力制定克服 LPS 实施挑战的策略。进行了系统的文献综述，随后是将研究结果和理论概念性地发展为一个强大的集成 LPS 实施模型。确定了实施 LPS 的十三 (13) 个主要缺点和克服这些缺点的十六 (16) 个精益工具。目前，LPS 作为单一实体进行管理。然而，由于它的多样性，它的所有阶段都应该独立管理。在这项研究中，精益工具被集成到 LPS 阶段，以开发创新的综合最后计划系统 (ILPS)，允许独立管理 LPS 阶段。此外，还提出了在不同阶段将 LPS 与精益工具顺序合并的指南，以简化 ILPS 实施过程。ILPS 将促进建筑业充分利用 LPS。
