Last Planner Control System Applied to a Chemical Plant Construction

Abstract

Abstract:The main difference between the Last Planner production control system developed by Ballard and classical control systems is the way in which projects are controlled and planned. The Last Planner system focuses on controlling production units, workflows and the quality of the performed work. It also permits the identification of the causes for the non-completion of planned work and decision making in accordance with the project requirements so that actions are timely and productivity is increased.The objective of this paper is to present the results obtained from implementing the Last Planner system in the construction department of a chemical company. In this department, an information flow problem was detected among its members, in which supervisors lacked knowledge about the work to be performed until the project had been perfectly designed. This problem often led to meant long delays in the projects.The results from Last Planner system implementation show that identifying the constraints of the planned work leads to an improvement in the percentage and quality of completed activities.

Application of Last Planner System to Modular Offshore Wind Construction

“…LPS was developed by Ballard (2000) following a design science research process, developing a model with principles, elements and functions was developed for the construction domain (Ballard 2000;Ballard and Tommelein 2016;Daniel et al 2019). The later utility of LPS in the construction domain has been established through multiple case studies (Abusalem 2018;Alsehaimi et al 2014;Castillo et al 2018;Daniel et al 2015;Daniel et al 2019;El-Sabek and McCabe 2018;Gao and Low 2014;Nieto-Morote and Ruz-Vila 2012;Priven and Sacks 2016;Seppänen et al 2010;Zaeri et al 2017). For successful LPS implementation within the construction domain; in mega projects El-Sabek and McCabe (2018) argues that interface alignment, including communication between sub-projects and sufficient training are some of the key factors.…”

Comparative Analysis and Evaluation of Bridge Construction Risk with Multiple Intelligent Algorithms

“…In addition, in terms of fuzzy evaluation methods, Ling et al [5] determined the evaluation indexes and corresponding weights of safety accident risk evaluation on construction site based on the statistical analysis of safety accident cases on construction site and constructed the membership function of fuzzy comprehensive evaluation. Nieto-morote and Ruz-Vila [6] combined fuzzy theory with AHP to evaluate the risk of a certain bridge construction stage. Wang et al [7], respectively, proposed the risk assessment method based on fuzzy decision, and applied these methods to the assessment of risk analysis of a bridge; the review of an actual bridge with traditional risk assessment methods are compared, and the results show that the proposed several new methods in bridge evaluation have a certain flexibility, practicality, and effectiveness.…”

Herramientas de trabajo colaborativo en el sector de la construcción español. Buenas prácticas para la implementación de la metodología “Último Planificador (LPS)”

“…On the other hand, and regarding the studies analyzed in the article, only few of them are written by Spanish authors (20,24,26) but none of them identify the obstacles or Best Practices (BP) to be implemented in relation to the LPS in Spain. As such, the present article has the following objectives:…”
