“…Aiding in research for a variety of publications on decision-making, modeling of operations, mine pit design and risk resolution rarely linked with the environment and mining industry planning. Moreover content on DS used in general operations of OPMs was not found, however works of Bouloiz et al (2013) provide an overview of DS for an organization and its related environment. The benefits are numerous, including: (1) monitoring of all system components, (2) aid in decision-making, (3) detailed analysis of influencing factors (IFs) as well as interactions and implementation of best practices.…”

The buoyancy of the minerals market, due to price and demand continually rising, maintains an increased interest for investors in mining. However, it is a sector particularly facing many negative environmental impacts, technical and environmental conditions to which are added the meeting of financial and production goals. Nevertheless in lockstep together, risk management of these extractive activities on environment -in this age where the society's level of awareness in ecological balance has evolved -continues to fuel discussions and interventions. Therefore, it becomes unavoidable to manage more effectively the environmental factors around mines. This study aims to propose the integration of environmental management (EM) tools based on dynamic simulation (DS) for mining. This research is structured in four main topics: (1) the dynamics of open-pits system, (2) the management of their environmental effects, (3) the EM tools at the disposal of managers and (4) the proposed EM by DS. The results show that the challenges are numerous and the volume of DS approaches in mining is constantly growing, even if only few are directed towards EM. Some approaches of DS in a few open-pits with the proven effectiveness, show a new opportunity to investigate.

Palabras clave:multinacionales, industria de software, dinámica de sistemas, Colombia, psicología organizacional, innovación tecnológica.Las multinacionales de software son agentes económicos con el potencial de afectar drásticamente la dinámica de desarrollo de la industria doméstica en este sector. Tales efectos dependen del tipo de relación (de competencia o colaboración) establecida entre las empresas. Respecto a la relación de competencia, la literatura revela avances en su comprensión sistémica. Sin embargo, el análisis del comportamiento colaborativo entre empresas multinacionales y nacionales de software y sus efectos sobre el desarrollo de estas últimas ha avanzado poco, siendo notable en la literatura la ausencia de modelos de simulación para analizar el fenómeno. El propósito de este trabajo es hacer una contribución en esta dirección, utilizando la Dinámica de Sistemas como aproximación metodológica. Los resultados obtenidos ponen en evidencia las condiciones favorables y desfavorables para el establecimiento de una relación de colaboración con multinacionales, conduciendo a una mejor comprensión del fenómeno bajo estudio y propiciando la formulación e implantación de estrategias más exitosas de crecimiento de la industria.

These effects depend on the type of relationship (competition or cooperation) between the companies. On the relationship of competition, the literature reveals progress in their systemic understanding. However, the analysis of collaborative behavior among national and multinational software companies and their effects on the development of the latter has advanced little, being notable in the literature the absence of simulation models to analyze the phenomenon. The purpose of this work is to make a contribution in this way, using the system dynamics as a methodological approach. The results obtained

“…When the important interactions in the analyses were evaluated, it was found out that 4-11 years experienced crusher workers working in the stone crushing -screening plants had high probability of NIHL because of high exposure to 90 -99dBA noise level. Bouloiz et al, (2013) presented an analysis, by a combination of dynamic systems and fuzzy logic, of the work environment of human factor. This environment contains a set of factors (variables) that influence human behaviour in the context of industrial safety.…”

It is widely known that quarry industry has great importance in developing countries, such as Nigeria. There is paucity of information regarding effects of noise experienced by quarry workers during their working time. Therefore, this study investigated the influence of age of workers, years of exposure of workers and noise level of the machine used in quarry on hearing threshold. A factorial design of experiment was employed for the investigation. Two hundred and four quarry workers volunteered for this study from four quarries in South western Nigeria. Emitted noise, which quarry workers were exposed to during machinery operation, was measured with a digital sound level meter and workers hearing threshold was measured in an audiogram sound proofing testing booth at standard conditions. Predicted models were established from experimental design to determine main and interactions effects towards the response (hearing threshold). These were statistically analysed using analysis of variance (ANOVA). All terms of the models were significant at p<0.05. The best fitted model was at 4kHz (R2 = 0.639, p<0.05). The magnitudes of the main effect of the factors are in ascending order of noise level >years of exposure>age. The analysis of the experimental response indicated that there is no interaction of any factors on the hearing threshold. It can be concluded that age, years of exposure and noise level have main effects at various capacities at different frequency to predict the hearing threshold of the quarry workers. This work determined the factors and the predicted model to spell out safe hearing threshold of quarry workers that fitted for the job at a particular noisy workstation as well as ensuring comfortable, safe and effective workstation design.
