In industrial contexts, the RTSDS-FPGA facilitates the optimization and tuning of embedded control algorithms, while in academia, it supports research on new embedded solutions in automation and control. It is also an educational tool for undergraduate and postgraduate students developing embedded control system projects. Additionally, the simulator accelerates the simulation of slow dynamic systems, significantly reducing overall simulation time. Experimental results demonstrate the platform’s capability to perform real-time simulations effectively, validating its accuracy and performance through comparative analyses with established software tools such as Matlab/Simulink.

A complete lean system design for team-oriented product development projects

PurposeThe inherent variability on process times and demand are the factors that prevent the efficient application of lean philosophy in multi-project product development (PD) environments. Considering this variability, a hybrid push–pull project control system is developed, and value stream costing (VSC) analysis is performed to reflect the relation between project lead time, capacity and project cost. The assessment of the push/pull project control on lead time improvement and long-term savings on capacity have been aimed with the proposed complete design structure.Design/methodology/approachIn a team-based structure, formed through clustering, push control techniques for planning tasks within cross-functional teams and pull control techniques for planning tasks between cross-functional teams are developed. The final step evaluates the proposed structure through VSC and long-term savings have been pointed out, especially in terms of freed-up capacity. For the validation of the proposed methodology, an office furniture manufacturing firm’s PD department has been considered and the performance of the hybrid system has been observed through simulation experiments and based on the simulation results, the lean system is evaluated by VSC.FindingsThe results of simulation experiments show a superior performance of the proposed hybrid push/pull project control mechanism under different settings of cycle time between projects or shortly project cycle time, dispatching rules within teams and variability levels. The results of the Box-Score (tool to apply VSC) indicate increased capacity in the long term to add extra projects during the planning period with the same project lead time and without additional cost.Research limitations/implicationsAlthough extensive simulation experiments have been performed to quantify the effect of project control structure and positive results have been reported on lead time and cost, the proposed design structure has not been tested in all existing PD environments.Originality/valueTo the best of authors’ knowledge, the quantification of the effect of hybrid project control with VSC is the first attempt to be applied in lean PD projects.

Decommissioning and restoration: early planning is critical to an efficient and risk-minimised process

Over the next 7 years, according to Wood Mackenzie, it is estimated that as many as 380 fields oil and gas facilities will be decommissioned across Asia–Pacific (Wood Mackenzie 2018). Many companies leave Decommissioning and Restoration (D&R) up to the respective project groups using their normal project management and control systems. However, managing D&R requires a different approach and mindset, as the value drivers and risk profiles for D&R projects are different compared to conventional construction projects. For D&R to be efficient – from operational, sustainability, regulatory compliance, environmental and financial perspectives – delivery must not be limited to an isolated project group. Rather, it must leverage corporate and operational knowledge, lessons learned from other decommissioning projects and industry best-practice to support the identification and management of the decommissioning risk profile and successful delivery thereof. Planning for D&R is essential at every stage of the life of an asset and should start as early as possible. Ideally, facilities are designed with D&R in mind at the project conception stage as the scope of D&R is often broader and more complex than operators realise, contributing to D&R projects often exceeding original cost estimates and timelines. Decommissioning and restoration opportunities may be missed or associated risks increased without timely recognition and management. In this paper, dss+ will provide companies with pragmatic guidance on how to plan and implement a D&R process that is managed well from an operational, risk, financial, contractor management and importantly, a stakeholder management point of view.

Practices and techniques for construction projects cost control- a critical review

ABSTRACT Cost performance problems and overruns were common and considered the major cause of projects due to not gaining the expected profit margin, With an 86% likelihood of overrun in international buildings projects, and at least 30%-40% of global projects experiencing subpar cost performance and overruns. The poor performance of project costs was attributed to inadequacies of project control systems, as they were responsible for monitoring project costs. Inadequate controlling systems suggest that established controlling tools fail to execute their function. Therefore, a successful control system was crucial to reducing project failure. Thus, The question that drives this study is ‘What were the successful cost practices and techniques commonly utilized in controlling construction expenditures and conserving project anticipated profit?’. Following PRISMA protocol guidelines, the study systematically reviewed the previous literature by searching academic databases for relevant articles. The study aimed to examine successful controlling strategies and tools commonly utilized. Fifteen common techniques were identified and found that budgeting monitoring, resources monitoring, interim valuation, unit costing, and cost variance analysis were successful, provided a comprehensive outline of each method, identified the fundamental ideas underlying technique differentiation, and summarized their benefits and drawbacks. Two controlling system implementation strategies were discussed, they were corrective and proactive approaches. A project development stage-based technique selection guide was proposed. The paper also proposed a control framework that integrated proactive and corrective measures into project control to inhibit overruns. The research also examined project controlling technique selection factors that should be considered when choosing the one.

A spherical fuzzy AHP model for contractor assessment during project life cycle

Abstract Measurement of construction performance is essential to a clear image of the present situation. This monitoring by the management team is necessary to identify locations where performance is exceptionally excellent or poor and to identify the primary reasons so that the lessons gained may be exported to the firm and its progress strengthened. This research attempts to construct an integrated mathematical model utilizing one of the recent methodologies for dealing with the fuzzy representation of experts’ knowledge and judgment considering hesitancy called spherical fuzzy analytic hierarchy process (SFAHP) method to assess the contractor’s performance per the project performance parameters (cost, schedule, quality, leadership, and change management). At the same time, most project control systems are currently applied through software like Primavera P6 or MS Project. These look at a project’s cost and schedule status by following the earned value analysis for finding the performance. Based on decision makers’ preferences, the analytic hierarchy process (AHP) may be used to arrive at the optimum conclusion. AHP approaches are discussed, including AHP, grey-AHP, fuzzy-AHP, and SFAHP weights comparison. Calculation results showed that the spherical fuzzy approach differs significantly from the other approaches where it considers the decision maker’s hesitation when making linguistic multicriteria decisions and then, as a result, recommends applying periodically for performance measurement. This model can be viewed as a valuable way to help the decision-making stakeholders in the construction sector do the best job about critical issues at a suitable time.
