In 2007, Vestal proposed Mixed-Criticality Scheduling (MCS) to increase utilisation despite imperfect timing evidence. Others have since refined the MCS problem formulation, proposed alternative scheduling approaches, and evaluated their performance. We assess existing MCS problem formulations from a safety assurance perspective and report problems found. Among these is the use of the word ‘cri...

The construction industry is responsible for one of the highest incidences of work-related accidents in Brazil, as well as in various other countries. In spite of the dissemination of prevention programs and the proposals for developing safety design for the construction industry, construction sites remain dangerous and unhealthy places. Recently, safety has been proposed to be considered from ...

it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...

This paper proposes a flexible solution methodology for solving the Vehicle Routing Problem with Stochastic Demands (VRPSD). The logic behind this methodology is to transform the issue of solving a given VRPSD instance into an issue of solving a small set of Capacitated Vehicle Routing Problem (CVRP) instances. Thus, our approach takes advantage of the fact that extremely efficient metaheuristi...

A b s t r a c t . We propose a general framework for assertion-based debugging of constraint logic programs. Assertions are linguistic constructions which allow expressing properties of programs. We define assertion schemas which allow writing (partial) specifications for constraint logic programs using quite general properties, including user-defined programs. The framework is aimed at detecti...

The construction industry ranks high in the rates of severe and fatal occupational injuries due to complexity and unpredictable nature of the tasks. Decades long efforts to combat occupational accidents by using various safety improvement approaches have reached a plateau. Figures published by Bureau of Labor Statistics show an improvement in the safety of the construction industry, yet a close...

Background Relative to other occupational groups in Britain, construction workers have a high incidence of skin cancer attributable to sun exposure. The importance of sun safety measures to minimize the risk of skin cancer is recognized in the literature; however, little is known about the factors associated with their use by construction workers. Knowledge in this area could help inform interv...

Leadership is a key factor impacting construction safety, but previous research merely investigated the single-level relationship between safety leadership and safety performance and ignored the leadership interaction between different project stakeholders. To fill this gap, this paper aims to examine the relationships between safety leaderships of project owners, contractors and subcontractors...
