Abstrakt: Several applications of darkroom is observed in modern technological applications. A darkroom can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper. Various equipments are used in the darkroom, including an enlarger, baths containing chemicals and running water. It is used to process photographic film, to make prints and to carry out other associated tasks. Also, in non-destructive testing such as magnetic particle inspection a darkroom is essential. Here, we studied the reliability of the illumination of a darkroom under different scenarios of the lighting systems. We have developed three models for illuminating the darkroom with a single operating switch with two tube lights, a single operating switch with multiple tube lights and multiple switches operating individual tube light. We have designed the simple unconstrained model and also the constrained redundancy allocation models. Moreover, we have considered the uncertainty models in the form of intuitionistic fuzzy number as it is the more generalization of the fuzzy numbers. In these imprecise models, the parameters along with the component reliabilities are taken as triangular intuitionistic fuzzy numbers. Before solving these imprecise models, we have crispified these into deterministic form by using suitable and efficient crispification method (BADD). The constrained redundancy allocation problems of integer programming type are obtained in each model and we have implemented evolutionary algorithm WQPSO to solve these problems successfully. Result analysis with comparison has been presented with the recommendation that the third model is more reliable in illuminating the darkroom. [ABSTRACT FROM AUTHOR]
