: To reduce the probability of secondary accidents caused by the direction deviation, body rollover, and excessive deceleration of runaway vehicles during braking on a truck escape ramp (TER), the safety of the occupants and the vehicles must be ensured. Based on the momentum theorem, an intelligent control method for a TER is proposed. In the method, a slope aggregate with a small rolling resistance coefficient is used on the original escape lane, and the information acquisition, braking device control, and braking modules are established. Through these modules, the operation parameters and control parameters of the out-of-control vehicle are obtained in advance, to control the operation state of the runaway vehicle. Achieve the purpose of reducing the braking effect of the slope bed aggregate and ensuring maximum utilization of the braking ramp. Finally, the proposed control method is simulated on the MATLAB/Simulink simulation platform. The results show that the control method can realize safe braking of an out-of-control vehicle at various speeds and different mass conditions, and it can play a highly significant role in the braking of high-speed and heavy-duty vehicles.

Delay in construction projects, especially in road and highway projects, is a universal phenomenon. Afghanistan construction industry is no exception. There are factors causing delays in the Afghanistan construction industry which have negative effects on the key project stakeholders and the project’s deliverables and outcomes. This research aims to identify the causes of delays that affect highway and road projects in Afghanistan and to provide recommendations in order to minimize or control delays in such projects. This will help, in return, facilitate and improve the delivery of roads and highways projects in Afghanistan. To achieve this aim, the study sets out to achieve the following objectives: 1) to determine the most important causes of delay that affect road and highway projects in Afghanistan, 2) to identify the severity of the delay causes from clients’ and contractors’ perspectives, 3) to investigate the differences and discrepancies between clients’ and contractors’ opinions and views, and based on first three objectives, 4) to finally provide recommendations for minimizing and/or controlling delays in road and highway projects, to improve the status-quo and to facilitate procurement/delivery of road and highway projects in Afghanistan. Causes of delay were gathered upon conducting a critical literature review of different types of construction, in different countries. An expert interview and a questionnaire survey formed the basis of this paper, listing 29 important causes of delay in such projects. The major causes of delay then were categorized into three groups following main stages of the highway projects, namely: 1) preparation, 2) procurement, and 3) implementation. The questionnaire survey was distributed to 100 construction participants and 79 were received who represent the government in road projects and contractors. Relative importance index (RII) was calculated and according to the highest values the top ten delay causes of road projects in Afghanistan were determined. Spearman correlation index was used to assess the correlation of causes and groups between clients and contractors. The findings of the study revealed that the top 10 significant factors causing a delay in road projects in Afghanistan are; security (war, theft, kidnapping, etc.), shortage of equipment and material or financial status of contractors, land acquisition, corruption in the procurement process, progress payment delays by owners/clients, non-consideration of security risks in the procurement process, Inaccurate design and bills of quantities, insufficient contractors’ experience, poor qualification of the contractors’ technical staff and award project to lowest bids. The findings will help clients and contractors to mitigate or prevent delays in road and highway projects in Afghanistan. Finally, to help overcome delays in road and highway projects more effectively, recommendations have been made for fundamental reforms in procurement systems for

Public procurement is the acquisition of works, goods, and services by procuring entities using public funds. The study assesses the level of compliance with the public procurement act (PPA) 2007 in the north-central states of Nigeria. Questionnaires were administered to construction stakeholders in those seven (7) institutions that make up the northern-central. A census survey was used to collect data from contractors, physical planning unit staff, consultants, and procurement administrative units that have executed Tertiary Institutions Fund (Tetfund) projects within 2012-2016. Data collected were analyzed using the relative importance index (RII), Kruskal Wallis, and Dunnett's test. The study revealed that all institutions have a good level of compliance with the tenet and component of the act for the procurement process. The study also shows that there is a significant difference in the level of compliance with the Act by Federal Universities. There was no significant difference in the level of compliance in University of Ilorin (UniIlorin) and Federal University Lafia (UniLafia), University of Abuja (UniAbuja) and Federal University Lokoja (FULokoja), University of Jos (UniJos), and Federal University of Technology Minna (FUT Minna), UniIlorin and FUT Minna, FULokoja and UniJos. The level of compliance of the National Open University of Nigeria (NOUN) is significantly different from other universities. The study indicated that the compliance level is very high, with an overall RII of 80.3% and 91.2% of respondents affirmation of the use of open competitive bidding, which represents fairness, accountability, and openness. The study also affirmed that understanding of tenets of the Act is very high in the study area. The study recommends that there should be a strong understanding between the stakeholders in the construction industry to increase the compliance rate of the PPA (2007) and enhance adequate monitoring of unethical behaviours.

The classic Cost-Volume-Profit (CVP) model cannot meet the needs of accurate decision-making under the new cost structure, and the time-driven activity-based costing can accurately and timely respond to rising overhead costs through accurate identification of time-related resource consumption. By relaxing the constraints of the CVP model, based on the time-driven activity-based costing method, this paper reclassifies and divides the cost behavior, constructs an extended CVP analysis model, and uses the operating data of Hunan Gongsheng Fengsheng Equipment Manufacturing Co., Ltd (GSFS) to conduct the empirical analysis. The results show that the extended model is reliable and effective.

This study explores the control degree in success criteria operationalization. A literature review reveals that control degree relates to two patterns operationalizing success criteria: one directed to measurement and measure selection; the other directed to operationalization through the conceptualization of a relationship between a specific factor and project success. While in both patterns tight control emerges, nevertheless a difference arises which implies that the control degree in these operationalization patterns varies. In the first pattern, control tends to be generic. The second provides opportunities to tailor the control of project success, considering the specific project and its context. Furthermore, this study shows that it is essential to include control suitability for making success criteria operationalization effective, in the sense of supporting project management to achieve project success. The theoretical contribution of this study is to link the field of project success and management control, adding that success criteria operationalization concerns control degree, i.e., tight/loose

Information and communication technology (ICT) is an important sector that contributes to the development of a country. However, the success of this sector depends on the success of the ICT projects. Hence, ICT projects must be managed efficiently and effectively to ensure that they are successfully implemented. The literature review reveals that most of the ICT projects around the globe are in a challenged state, especially in terms of cost. This quantitative research aims to explore the cost influencing factors of the ICT projects in Malaysia and to build a cost influencing factors framework as a knowledge base for project managers. A 5-point Likert scale survey was conducted using the purposive sampling and the snowball sampling method to solicit responses from a large population of ICT project managers. The responses of 194 ICT project managers in Malaysia were analyzed, and the top 15 cost influencing factors were identified at different phases of a project. This result was used to build a cost influencing factors framework as a knowledge base for ICT project management.

An effective way to solve the problem of urban traffic congestion is to predict the road traffic status accurately and take effective traffic control measures in time. Considering the impact of visibility on traffic, the pavement status and time characteristics were finely divided, and a regression decision tree was used to establish the traffic flow velocity prediction model with pavement status, time characteristics, and working day characteristics as characteristic parameters. Furthermore, based on the perspective of avoiding using velocity as a single parameter to classify the road traffic status levels, the Kmeans clustering algorithm was used to obtain the classification label results. Moreover, the traffic flow velocity and pavement status were used as characteristic parameters of the classification decision tree to establish the multi-parameter road traffic status prediction model. The experimental result showed that the prediction accuracy of the proposed road traffic status prediction model was 81.31%, and this method has good applicability and certain application value for road traffic status prediction.

Maturity models (MMs) have witnessed exponential increase due to their successful application in several domains. However, there is an absence of review that guides researchers in developing, applying and validating Public-Private Partnership maturity models (PPPMMs). This study examines PPPMMs, provides guidance on the topic and highlights gaps in the literature. A literature search on selected electronic databases was conducted, and the study adopted the widely accepted Preferred Reporting Items for Systematic Review and Meta-analysis statement (PRISMA). The study identified a total of four thousand six hundred and eighteen (4,618) studies, and twenty-one studies (21Nr) were rigorously selected. The results revealed PPPMMs as an emerging area of research with a low number – 21 publications since its deployment for about two (2) decades. Similarly, the findings unveiled a lack of uniformity in conceptualising the terms, dimensions used, and methodology adopted. This finding is attributed mainly to the limited use of the theoretical lens, which considerably weakens the model’s theoretical foundation and limits its potential to guide improvement. Additionally, there are more efforts in developing MMs than applying and validating them. Furthermore, there is an unbalanced focus on descriptive models over prescriptive and comparative models, which inhibit the model’s potential to guide improvement. Future work should provide a solid ground to the field using a theoretical lens and focus on prescriptive models with a strong emphasis on application and validation. This research is the first of its kind that synthesises and brings together available PPPMMs literature into one place. It also contributes to the body of knowledge by highlighting areas of research that require immediate attention to enhance the much-needed success of PPP in the post-COVID-19 era.

In this research, the Servperf method is used to analyze the quality of health and safety services. The main purpose of this article is to determine the quality level of preventive health and safety services provided in the workplaces within the framework of the perception of the employees who benefit from these services. The questionnaire prepared in accordance with the Servperf method was applied to 412 employees working in various sectors, and the results were classified according to age, gender, education level, sector, and the way of providing (internal & external) services. Descriptive statistics were used in the evaluation of results. The total perceived Servperf score of the health and safety services was 2.84, medium level. As the age and education level of the employees increases, the satisfaction level and Servperf scores of the service quality decrease. The satisfaction score of the construction workers is significantly lower than the other sectors. Satisfaction levels of employees in the workplaces where services are provided internally are higher than those of the workplaces offering external sources. Despite legal regulations related to preventive health and safety services, accidents have not decreased in Turkey. The quality of the service provided by external health and safety units is significantly low. Competition arising from the marketization of occupational health and safety services reduces the quality of the service provided. For these reasons, the number of research aimed at determining the quality of these services should be increased both in Turkey and in the world.

The satisfaction score of the construction workers is significantly lower than the other sectors. Satisfaction levels of employees in the workplaces where services are provided internally are higher than those of the workplaces offering external sources. Despite legal regulations related to preventive health and safety services, accidents have not decreased in Turkey. The quality of the service provided by external health and safety units is significantly low. Competition arising from the marketization of occupational health and safety services reduces the quality of the service provided. For these reasons, the number of research aimed at determining the quality of these services should be increased both in Turkey and in the world.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46843962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
