<span style="font-family: 'Times New Roman','serif'; font-size: 10pt; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: EN-GB; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;" lang="EN-GB">This paper aims to provide brief overview of aviation safety development focusing on modern trends represented by implementation of Safety Key Performance Indicators. Even though aviation is perceived as safe means of transport, it is still struggling with its complexity given by long-term growth and robustness which it has reached today. Thus nowadays safety issues are much more complex and harder to handle than ever before. We are more and more concerned about organizational factors and control mechanisms which have potential to further increase level of aviation safety. Within this paper we will not only introduce the concept of Key Performance Indicators in area of aviation safety as an efficient control mechanism, but also analyse available legislation and documentation. Finally we will propose complex set of indicators which could be applied to Czech Air Navigation Service Provider.</span>

Abstract:

The safety performance of a 737-mm (29-in.)-high open concrete bridge railing was evaluated. The evaluation included four full-scale crash tests, investigating two critical impact locations where structural failure was most likely to occur. Each impact location was evaluated with a single-unit truck and a ballasted pickup truck. The safety performance of the 737-mm-high open concrete bridge rail was shown to meet the Performance Level 2 requirements specified in the AASHTO Guide Specifications for Bridge Railings (1989).

Abstract:

Purpose The purpose of this paper is to explain the effects of inherent differentiation and system level performance assessment in inventory management. This is done by comparing the performance of two common safety stock methods, by considering the methods’ inherent differentiation and item group-level performance effects. Design/methodology/approach Due to the lack of analytical relationships between the two methods, the analysis is based on event-driven simulations. Data are collected from eight different case companies. Findings explain the importance of assessing safety stock performance for groups of items and not for individual items, as is common in academic studies. It explains how the methods’ inherent differentiation and planning environment characteristics affect the relative performances of the two safety stock methods. Findings The study explains the importance of assessing performance of safety stock methods on a system-level, rather than on item-level measures. It explains why the demand fill-rate method has a negative impact on the performance for groups of items, while the number-of-days method has a positive impact. The study also explains how the group-level safety stock performance is affected by five demand data characteristics. Research limitations/implications The study explains the importance of assessing performance of safety stock methods on a system-level, rather than on item-level measures. It explains why the demand fill-rate method has a negative impact on the performance for groups of items, while the number-of-days method has a positive impact. The study also explains how the group-level safety stock performance is affected by five demand data characteristics. Practical implications Understanding the necessity of system level assessment of safety stock performance, how methods inherently differentiate service levels, and how demand characteristics affect methods’ performance can guide the choice of safety stock methods in companies. Originality/value No research on the characteristics of the number-of-days safety stock method, any assessment of differentiation characteristics of and comparison with the demand fill-rate method, has been published. The variable “inherent differentiation” is also introduced and defined.

Abstract:

Purpose Previous research studies have testified that safety culture positively affects safety performance. However, the progression by which safety culture affects safety performance has not yet been examined. Also, how safety culture affects the overall safety performance at different levels of the organization is yet to be explored. In order to address this issue, the purpose of this paper is to study the effect of multilevel safety culture upon safety performance over time. Design/methodology/approach A conceptual causal-loop diagram is constructed using the group model building approach to establish the relationship between safety culture components (e.g. psychological, behavioral and situational) and the factors associated with safety performance (e.g. risk level, safety behavior, unsafe conditions, unsafe acts and incident rate). Considering the dynamic nature and intricacy of the safety management system, the system dynamics approach has been employed to develop the model. Findings The results indicate that the safety culture at the tactical level (middle management) and operational level is much more effective than strategic level (top management) in ameliorating the safety performance of the organization. Research limitations/implications The scope of this study is limited to the effect of multilevel safety culture on safety performance. The focus is on the dynamics of personal, behavioral and situational factors of top management, middle management and workers to reinforce the safety performance of the organization. Future research can be protracted to build other models of safety. Practical implications First and foremost, the findings summarized in this paper can be implemented by organizations to achieve the total safety culture to upgrade safety performance. Originality/value This paper presents the holistic view of multilevel safety culture in an organization’s hierarchy. It shows how multilevel level safety culture in an organization interacts with the safety management system to enhance the safety performance of the organization.

Abstract:

Due to the great increase of congestion levels on transportation infrastructures researchers and practitioners have focused on the study of safety performance on road network to identify unsafe locations and assess the effectiveness of different countermeasures introduced at a given site to reduce unacceptable accident risk. Safety performance measures represent an useful tool for evaluating road safety conditions on the basis of objective parameters deducible from the vehicle kinematics. The focus of the present paper is on the assessment of the safety level on two-lane rural highway with a particular attention on rear-end interactions among different pairs of vehicles belonging to the traffic stream. The roadway safety performance study is based on the traffic conflict technique applied to vehicle maneuvers obtained experimentally from a frame by frame analysis of video-taped traffic data. The authors also explored qualitatively the possible relationship between safety level and traffic level of service. This aspect is very important because this kind of roads represents a large part of non-urban highways in many countries.

Abstract:

The general building conditions in low cost housing are part of human’s quality indicator. However, there are rising issues on the safety performance of the housing since the occupants are inclined to perceive safety hazards. Therefore, this paper explores the concept of Post Occupancy Evaluation (POE) as safety performance tool. This research conducted a survey on safety performance and occupants’ satisfaction to 24 numbers of low cost housing at Kuala Lumpur, Malaysia. The correlation result shows that safety performance has a significant relationship with occupants’ satisfaction. The findings supported the application of POE as the tool for safety performance.

Abstract:

Security is the main direction of ammunition for future development. Depending on the security level that ammunition relative to its life process may suffer major environmental stimuli factors, raising ammunition’s safety criterion, introducing safety parameters, establishing a theoretical model of ammunition safety performance evaluation. In the model, based on the value of the safety of ammunition, we divides the security level of ammunition. Based on this evaluation model to calculate the conventional bomb safety performance of the changing Mk-82’s insensitivity. We analyzed the influence of unexploded ordnance (UXO) on the overall safety performance of ammunition from the failure of the design. The results show that the end of unexploded failure design can significantly improve the safety level of ammunition. This model better reflects the inherent safety performance of ammunition, can provide theoretical guidance for the safety design of ammunition and safety performance evaluation.

Abstract:

Yogyakarta, one of the middle cities in Indonesia, has been developing BRT system named Trans Jogja to reduce growth of motorization. However, the performance tends to decrease year by year, therefore the system and management upgrading must be carried out continuously to restore public trust. This research tries to investigate public satisfaction, their expectation, and some attributes considered important based on public’s perspective using IPA method that can be used as useful information systems to evaluate service quality by prioritizing or focusing on areas where improvement is needed. The results reveal that decision maker must focus and allocate their resources to improve Trans Jogja system on the following attributes: a) keep punctuality, b) shorten waiting time in the bus stop, c) improve bus comfort, d) provide safety for child passenger, e) improve bus stop comfort, f) create new bus route to enlarge accessibility, and g) shorten bus travel time.

Abstract:

This paper presents macro-level safety performance functions and aims to provide empirical tools for planners and engineers to conduct proactive analyses, promote more sustainable development patterns, and reduce road crashes. In the past decade, several studies have been conducted for crash modeling at a macro-level, yet in Italy, macro-level safety performance functions have neither been calibrated nor used, until now. Therefore, for Italy to be able to fully benefit from applying these models, it is necessary to calibrate the models to local conditions. Generalized linear modelling techniques were used to fit the models, and a negative binomial distribution error structure was assumed. The study used a sample of 15,254 crashes which occurred in the period of 2009–2011 in Naples, Italy. Four traffic analysis zones (TAZ) levels were used, as one of the aims of this paper is to check the extent to which these zoning levels help in addressing the issue. The models were developed by the stepwise forward procedure using explanatory Socio-Demographic (S-D), Transportation Demand Management (TDM), and Exposure variables. The most significant variables were: children and young people placed in re-education projects, population, population aged 65 and above, population aged 25 to 44, male population, total vehicle kilometers traveled, average congestion level, average speed, number of trips originating in the TAZ, number of trips ending in the TAZ, number of total trips and, number of bus stops served per hour. An important result of the study is that children and young people placed in re-education projects negatively affects the frequency of crashes, i.e., it has a positive safety effect. This demonstrates the effectiveness of education projects, especially on children from disadvantaged neighbourhoods.

Abstract:

ABSTRACT Physician performance failures are not rare and pose substantial threats to patient welfare and safety. Few hospitals respond to such failures promptly or effectively. Failure to ensure the quality and safety of the performance of colleagues is a breach of medicine’s fiduciary responsibility to the public. A major reason for this deficiency is the hospitals’ lack of formal systems to monitor physician performance and to identify and correct shortcomings. To develop and implement these systems, hospitals need better performance measures and substantial expansion of external programs for assessment and remediation. This is a task well beyond the capacities of individual hospitals; a national effort is required. The authors call on the Federation of State Medical Boards, the American Board of Medical Specialties and The Joint Commission (organizations that already bear a fiduciary responsibility for ensuring safe, competent care) to collaborate on developing better methods for measuring performance and to expand programs for helping practitioners who are deficient.

Abstract:

The key persons in safety activities at enterprises are: top manager, his(her) representatives, working environment specialist, all acting for the employer; and working environment representatives, selected by the workers and holding the workers’ rights in safety and health area. The main possibilities to improve the safety level in the firm have the working environment specialists, as they are usually educated and supported by the employer and the law. The current paper is looking for the possibilities to raise the employers’ interest for improvement of their knowledge in safety and through this also the safety level in the workplace. Safety level in 12 Estonian enterprises was investigated using MISHA method (based on standard OHSAS 18001). Some of the firms have implemented OHSAS 18001 or belong to the foreign companies. The investigated enterprises were from different industries and agriculture firms. The safety level is very much depended on the owner of the firm. The larger the enterprise is the better are the possibilities to educate the employers and employees. One of the ideas to improve the safety level at enterprise is the method “learning through the interviews”. The interview is worked out basing on MISHA method. The latter is a tool of quantitative study. The safety performance key elements were divided into three parts: formal, real, combined ones. Three hypothesis were formulated and the area in which they are proved concerning employer’s activities were as follows: H1) Standard OHSAS 18001 has an impact on Formal safety performance in companies (p value< 0.013) – if OHSAS 18001 has been implemented, then: the assignment of tasks and responsibilities in OHS is committed to the top management, the employer is revising the safety policy, and the personnel’s responsibilities in OHS are clearly defined. H2) Standard OHSAS 18001 has an impact on Real safety performance. (p< 0.013) - if OHSAS 18001 is implemented, then: the top manager promotes dissemination of safety policy: the policy is made available to all of the personnel; resources for improvement are arranged by the top management; the top manager arranges meetings in OHS; there is a system for redesigning the workplaces for the persons who have difficulties in coping with the work. H3) Standard OHSAS 18001 has an impact on Combined safety performance (p< 0.007) - if OHSAS 18001 implemented, then: the top management is participating in the preparation of safety policy, top manager is reviewing the safety policy, is it operating effectively? He is informing the external bodies about the company’s safety policy’s effectiveness; the top manager arranges safety training for all of the personnel; there is a plan for reduction of accidents; it has been elaborated by the top manager; the company has a system for measuring the social climate in the company.

Abstract:

PurposeSafety management system (SMS) has been widely adopted to explore its influence on safety performance (SP). However, most existing researches recognized SMS as a one-dimension structure and neglected the influences of its subdimensions. Similarly, the impact of safety responsibility (SR) on SP received little attention. This study aims to explore the relationship between subdimensions of SMS and SP, while incorporating the mediating effect of SR.Design/methodology/approachThe research data were gathered from safety management evaluation report of a large real estate enterprise in China during 2010–2017. This paper carries out a series of data analyses to explore the impact of SMS and SR on SP. In order to analyze the synergistic impacts of SMS and SR on SP, path analysis, correlation analysis and mediation analysis were conducted using hypotheses concerning with the main subdimensions.FindingsThe results indicated SMS and SR decreased the project risk level and improved SP of real estate projects. Furthermore, the effect of SR partially mediated the relationship between the SMS and SP.Practical implicationsFindings in this research contribute to improve SP in real estate industry as well as other industries by the active assumption of SR and the successful implementation of SMS.Originality/valueThis research shows the relationship between subdimensions of SMS and SP and the mediating role of SR on SMS–SP relationship to improve SP in real estate industry.

Abstract The article presents a method for determining the performance level (PL) on the basis of the PN-EN ISO 13849-1 standard, which is harmonized with the machinery directive 2006/42/EC. The risk assessment and risk reduction criteria, according to PN-EN ISO 12100, were briefly characterized. The focus was put on determining the required performance level PLr on the basis of a risk graph. The method was presented how to use a safety function composed of input-, logicaland execution subsystems. It was demonstrated how to determine the achieved PL for a safety function composed of hardware elements on the basis of a safety category, mean time to dangerous failures (MTTFd), diagnostic coverage (DC), and immunity to common cause failures (CCF).

Abstract:

The paper introduces a conceptual framework that could improve the safety performance measurement process and ultimately the aviation system safety performance. The framework provides an implementation guide on how organisations could design and develop a proactive, measurement tool for assessing and measuring the Acceptable Level of Safety Performance (ALoSP) at sigma (σ) level, a statistical measurement unit. In fact, the methodology adapts and combines quality management tools, a leading indicators programme and Lean-Six Sigma methodology to formally measure and continuously improve a stable and in-control safety management process by reducing safety defects and variability from core organisational processes and objectives. The implementation guide was empirically tested and validated with data collected and analysed within a period of nine months by the safety department of a complex aviation organisation operating a large transport aircraft fleet.

Abstract:

Purpose The purpose of this paper is to offer six principles that health system leaders can apply to establish a governance and management system for the quality of care and patient safety. Design/methodology/approach Leaders of a large academic health system set a goal of high reliability and formed a quality board committee in 2011 to oversee quality and patient safety everywhere care was delivered. Leaders of the health system and every entity, including inpatient hospitals, home care companies, and ambulatory services staff the committee. The committee works with the management for each entity to set and achieve quality goals. Through this work, the six principles emerged to address management structures and processes. Findings The principles are: ensure there is oversight for quality everywhere care is delivered under the health system; create a framework to organize and report the work; identify care areas where quality is ambiguous or underdeveloped (i.e. islands of quality) and work to ensure there is reporting and accountability for quality measures; create a consolidated quality statement similar to a financial statement; ensure the integrity of the data used to measure and report quality and safety performance; and transparently report performance and create an explicit accountability model. Originality/value This governance and management system for quality and safety functions similar to a finance system, with quality performance documented and reported, data integrity monitored, and accountability for performance from board to bedside. To the authors’ knowledge, this is the first description of how a board has taken this type of systematic approach to oversee the quality of care.

Abstract:

A study was conducted to determine if primary flight displays (PFDs) depicting terrain could be used with a level of safety equivalent to electronic attitude-direction indicators (EADIs) without terrain. Five groups of 8 pilots each flew scenarios in a flight simulator using one of three PFDs with or without guidance cues. Performances of instrument-referenced maneuvers using the EADI were measured, followed by trials with an experimental format. Performance measures included initial response time, total recovery time, and control reversals. Traditional parametric analyses found no significant performance differences between groups. Analyses using confidence intervals to assess equivalence of distributions showed group performances were essentially the same. Pilot preferences were examined and are reported. It was concluded that the specific terrain representations did not reduce the level of safety for these specific maneuvers. This technique is recommended for applicants wishing to demonstrate a level of safety equivalent to existing systems.

Abstract An important role among protective means play the elements of control systems performing safety functions. When the validation process of a safety performance level(PL) achieved by those systems is conducted properly one can draw the conclusion that any defect appearing in those systems would not cause the loss of safety functions. The paper presents formalized validation of the PL procedures for different categories and PL’s for introducing into the computer program which makes more efficient all the operations involved into the validation and documentation processes of safety performance level achieved by machine control systems.

Abstract:

Level crossing, also known as railroad and highway crossings, pose a risk to those who use both modes of transport due to collisions that may occur. This risk associated with level crossings is of great importance both in Turkey and in the world. In this study, data envelopment analysis was performed on the accident data occurring on five types of level crossings in Turkey and a measurement of safety performances of level crossings in Turkey was provided. As a result of the analysis, the most efficient three-level crossings were found to be Hilal-Bandırma in Manisa, Samsun-Kalın in Amasya_1, and Samsun-Kalın in Amasya_2. In addition, a linear regression model that serves with the variables which are the components of level crossing and the number of accidents is established. In this model, it is seen that the ratio of independent variables to dependent variables was statistically significant.

Abstract:

Purpose The purpose of this paper is to address the primary research question, which is what is the relationship between the project manager’s (PM) possession of the Project Management Professional (PMP) certification and the level of the safety culture present in the construction project the PM manages. Design/methodology/approach The research was based on a survey of a purposive sample, 109 engineers and first-line supervisors worked in 23 construction projects of which ten were led by PMP-certified PMs and 13 were led by PMs lacking PMP certification. Each PM completed a demographic questionnaire for the predictor variables of PMP certification controlled for age and experience. To assess the criterion variable of safety culture total score, engineers and first-line supervisors working in the same project completed the questionnaire of safety culture values and practices. Findings Results of this study indicated the level of safety culture was significantly different, and improved, for engineers and first-line supervisors who work under PMs with PMP certification compared to the level of safety culture in projects managed by PMs with no PMP certification. Although alignment of safety culture perceptions among different levels in the organization helps to achieve a positive safety culture, the role of the PM in transferring, implementing and maintaining the safety culture in the construction project is fundamental, particularly in small-to-medium sized enterprises (SMEs). Originality/value This study addressed the role of the PMs managerial skills in the safety performance of Saudi Arabian SMEs. The principal finding was that PMs with managerial skills perform better regarding safety performance in SME construction projects than PMs lacking managerial skills. The primary recommendation is that leaders in construction projects must carefully evaluate engineers’ managerial skills before hiring the individuals as PMs. A PM’s promotion model developed in this study provides a suitable framework and business process component for construction leaders seeking to maintain safety performance successfully.

Abstract:

Deterioration of bridges due to ageing and higher demands, induced by increased traffic load, require the development of effective maintenance policies and intervention strategies. Such concern should be aimed at ensuring the required levels of safety, while optimally managing the limited economic resources. This approach requires a transversal advance; from the element level, through the system level, all the way to the network level. At the same time intervention prioritisation based on the importance of the system (bridge) inside the network (e.g. highway), or of the single structural element inside the bridge is dependent. The first step in bridge condition assessment is the verification of safety and reliability requirements that is carried out using the traditional prescriptive (deterministic) approach or the current performance- based (probabilistic) approach. A critical issue for efficient management of infrastructures lies in the available knowledge on condition and performance of bridge asset. This information is obtained using a collection of significant Performance Parameters at one or more of the three levels (element, system, and network). Traditional techniques for estimation of Performance Parameters rely on already established visual inspection. However, a more reliable description of the system performance is obtained through Non-Destructive Testing and Structural Health Monitoring. Condition assessment essentially pertains to the check of compliance with Performance Goals and requires the definition and computation of Performance Indicators. They are calculated directly from Performance Parameters or from physical models calibrated using the Performance Parameters collected on the structure. Paper overviews the steps to bridge condition assessment regarding safety and reliability.

Abstract:

The construction industry contributes to a large proportion of industrial injury and mortality. It is of high importance to evaluate the effectiveness of the Safety Management System (SMS). In particular, it is necessary to compare the quality and level of achievement of SMS and safety performance of a construction project. However, a sizeable sample of construction accidents is often not available. Therefore, possible proxies to indicate the safety performance were established. Moreover, the motivation factors which characterize the quality and level of achievement should be identified. In this study, a structural model has been established to examine the relationship between the SMS implementation and operational & safety performance of the construction projects. Results of the structural model illustrated the relationship between (i) SMS implementation and project safety outcome, (ii) SMS implementation and five motivation factors, and (iii) project safety outcome and six proxies. Results of this study have unfolded the motivation factors in SMS implementation and their subsequent effects on project performance, throwing light on the need to enhance the safety management practice in order to reduce accidents and injuries in the construction industry in the long run.

Abstract:

There has been a considerable amount of research in the area of network performance evaluation. However, little of the research is focused on the evaluation of real-time safety-critical WANs, a need that motivated this research. Over the years, networks have been evaluated by different disciplines from different perspectives. Many of these evaluations focus on network technical performance, or an organization's performance when using a network, or individual users' performance when using a network. In this study, network performance was measured using empirical data from an operational WAN and by utilizing well-defined and well-known network performance metrics such as reliability, availability, and response time. In general, increased use of a real-time WAN in this study was associated with negative impacts on WAN performance and increased redundancy was generally associated with positive impacts, allowing greater system usage and higher network workload, as intended. The impacts of increasing redundancy on MTBF were mixed, as were the MTTR impacts; availability values varied considerably by port. The network performance data thus shows mixed empirical results from increases in network usage and redundancy, which highlights the importance of managing and measuring network performance at both the system and the local level.

Abstract In this article, the authors offer a methodology for determining the quality of airline performance by taking into account the level of flight safety on the basis of factor analysis and the results of methodology approbation in the conditions of a functioning airline. The assessment of the level of airline performance quality taking into account the level of flight safety within a certain time span is rather sensitive, informative and reliable. They allow us to detect those changes in industrial and economic conditions and factors that are related to a certain degree of potential deterioration of flight safety. This creates conditions for revealing the tendencies towards the deterioration of flight safety at the stage of their origin, when they have not yet caused deep, irreversible changes in the flight safety of an airline.

Abstract:

While some initial and significant progress has been made in the development of a highway safety manual, much remains to be done in the areas of conceptual development and the diagnostics of safety problems. The concept of level of service of safety (LOSS) in the framework of safety performance function is introduced, and the problem of diagnostics is addressed. LOSS reflects how the roadway segment is performing in regard to its expected accident frequency and severity at a specific level of annual average daily traffic. It provides a comparison of accident frequency and severity only with the expected norms; it does not, however, provide any information related to the nature of the safety problem itself. If the safety problem is present, LOSS will describe only its magnitude. The nature of the problem is determined through diagnostic analysis by direct diagnostics and pattern recognition techniques, which are also discussed.
