“…If we know the application scenarios in advance, it's possible to optimize the I-table so as to design a luminaire with optimal optical performance and capable of producing a more energy-efficient, higher quality lighting environment [2][3] [4]. Genetics Algorithm (GA) is employed in this paper to optimize the luminous intensity distribution of roadway luminaire in order to satisfy with roadway lighting quality.…”

Uniformity of overall and longitudinal (U o , U L ) are two important items to evaluate roadway lighting quality. The fitness function incorporates two adaptive parameters in order to take both U o and U L into consideration as multi-objective function for genetic algorithm. Installation geometry is specified to build up direct connection between I-table and rtable to result in an optimal I-table for R3 road surface. It proves that the application of GA to optimize I-table is feasible in this paper.

“…The CIE 088 report (CIE, 2004) is used by most countries in the world. Pachamanov (2008) studied tunnel-lighting settings that meet brightness and glare requirements, considering the transition of lighting as a linear optimization problem between lights and pavement reflection [3]. Then lighting installation and commissioning of the illuminance transition are curve fitting.…”

“…Optimisation studies accounting for light obtrusiveness are mostly related to road luminaires where observers are taken as vehicle drivers [29], with little or no attention directed at limiting light pollution at other types of light sensitive receivers. As such, we propose a location model to optimise the location of floodlights around a construction site while ensuring that light intensities at light sensitive receivers, in the vicinity of the construction site, are kept to a minimum.…”

The increase in the rate of urbanisation worldwide has led to a boom in the construction industry sector in most major cities. To cope with the associated rising demand for further services and facilities, contractors find themselves frequently obliged to extend working hours on construction sites. Construction of major infrastructure projects, such as road works, is conducted at times of the day when less disruption is likely to result to the affected population. As a result, night work is now a common sighting on many construction sites. To allow for better vision for construction personnel on sites, floodlights are deployed during night work to light up work zones. There is an expense however to the adoption of construction lighting, particularly when considering the social and environmental impacts arising due to light pollution. In a residential district, and especially when infrastructure projects are taking place, the lighting system utilised on a construction site can be a cause of major disruption to the people and wildlife in the vicinity of the site. This paper attempts to model the problem of construction lighting through an optimisation model that minimises both construction light set-up costs and the maximum light pollution perceived at lightsensitive receivers. At the same time, the model ensures an appropriate coverage level to avoid impairing workers' vision on site. The developed formulations take the format of a Mixed Integer Programming model. An illustrative case study is applied to a construction project to demonstrate the applicability of the model.
