“…Takt-time planning is carried out by first determining preliminary Takt and planning the work zones, then optimizing labor, space, and duration assignments to enhance a smooth flow of workers entering and leaving a workspace at a fixed time interval (Takt), one crew at a time. The uniqueness of Takt-time planning is that it assigns only one crew to work in a specific space within a Takt, minimizing the chance of overcrowding or work waiting for workers to protect productivity [12,13]. The Takt-time planning method ensures continuity and stability in the execution of work and defines clear handoffs between operators to facilitate coordination and control [14,15].…”

“…Lerche et al applied Takt-time scheduling to the assembly of six towers in an offshore project, and the intervention reduced the time per tower module by nine days and the loading interval by 3.6 days, which reduced wastage and uncertainty in the construction schedule [13]. Kimmo et al applied Takt-time scheduling to a project of about 200 units of a refurbished apartment building, and the rationalization of the Takt-time and the division of areas allowed the building to be delivered on time, and pointed out that Takt production must be planned [16].…”

The complexity and uncertainty of construction projects contribute to low efficiency in the construction industry. This research applied the Takt-time planning method to optimize the construction working process, and proposed a risk control framework based on Value at Risk (VaR) and Conditional Value at Risk (CVaR) approaches to explore and predict a project schedule and cost performance under different scenarios. This research selected a high-rise residential building project for a case study and collected 1672 productivity data samples. Arena Simulation models were established based on 90 combinations of labor assignments to assess Takt-time planning strategies’ impact on project performance in four scenarios. The VaR and CVaR evaluations at 75% and 90% confidence levels were compared to balance project benefits and risks. Without any overtime or additional workers, this research found a Takt-time planning method that can reduce the project duration by 20.2% and labor costs by 2.1% at the same time, using a labor assignment of 12 bar placers, 12 carpenters, and 5 pipefitters. The findings can assist construction managers to achieve a shorter duration, reduced cost, and safer work environment, which will be very effective and beneficial to improve project overall performance.

“…Other studies adopted cross process simulations to integrate information of different processes to optimise total time and cost (Heravi et al 2021), carbon emissions (Heravi et al 2020), and digitalisation efficiency (Barkokebas et al 2021a). Further, takt planning is employed to synchronise production information necessary to smooth resource utilisation (Chauhan et al 2018), and reduce delays (Lerche et al 2022). Other studies adopted Design for Manufacture and Assembly (DfMA) principles to synchronise design information with manufacturing and assembly processes to verify design geometry prior to production (He et al 2021), and improve site safety and logistics efficiency (Banks et al 2018).…”

“…Real-time production monitoring systems facilitate proactive detection of process waste and so stimulate timely mitigating decisions (Snatkin et al 2013). Other studies used the lean concept of takt planning to synchronise production rhythm with actual market demand, reporting several benefits including resource optimisation (Chauhan et al 2018) and productivity improvements (Lerche et al 2022). For logistics tracking & control, component level data (e.g., location and class) are synchronised in real-time using module tracking technologies, such as RFID and IoT to optimise logistics cost and efficiency (Wang et al 2020a), and support on-time deliveries (Xu et al 2018).…”

Lean manufacturing principles are being increasingly employed in off-site construction (OSC), with the primary objective to reduce waste and improve production efficiency. This is performed using several tools and technologies largely influenced by the concept of Industry 4.0 (I4.0) which sets fundamental design principles for technological development. However, the recent introduction of the concept of Industry 5.0 (I5.0) extends I4.0 focus towards wider economic, social, and environmental implications.This study aims to evaluate extant literature employing lean tools and concepts in OSC towards the realisation of I4.0 and I5.0 design principles, identifying key research themes and gaps and suggesting future directions. A mixed method review was employed to firstly identify highly relevant literature using bibliometric search. The identified references were then analysed using qualitative content analysis through the lens of I4.0 and I5.0. Results highlight several interactions between identified lean-OSC tools and concepts, and I4.0 and I5.0 design principles, signifying the power of these tools/concepts in meeting multiple industry objectives. The review also identifies significant overlap between resilience principle in I5.0 and many of I4.0 principles, emphasising resilience as an integrative concept of technological principles. Finally, several research gaps relating to the social and environmental aspects of lean-OSC research were identified, including research on mental health, assistive technologies, and design for end-of-life.

“…The thematic has already been so explored and revised over time. Nevertheless, the PDCA cycle remains the preferred one: it is simple, it is founded in four basilar stages, according to the Kaizen perspective, and it is a proven effective approach for CI -see recent work of Franco-Quispe et al ( 2022), Ghatorha et al (2022) and Lerche et al (2022). For the mentioned reasons, the PDCA cycle is the chosen methodology for what follows.…”

PDCA Protocol to ensure a Data-Driven Approach for Problem-Solving

Proceedings of the International Conference on Industrial Engineering and Operations Management

Problem-solving based, as much as possible, on real data, expert knowledge, and on-field observation are quite desired objectives. However, it creates several difficulties on deployment in real situations. In this work, a data-driven version of the well-known PDCA cycle is proposed for continuous improvement within a general class of problems represented by key performance indicators (KPI). Such class is wide enough to accommodate several real problems but still has a controlled level of complexity that allows defining a general data-driven protocol that covers all the (sub)steps of the cycle. New approaches and alternatives in the literature are discussed. A brief example of one of the steps of the protocol is given with real data from a company that adopts many of the new Industry 4.0 technologies.
