This study proposes a new approach for single-sampling plan by determining sample size and acceptance number. The proposed approach is based on a two-step methodology. In the first step: quality management step, different single sampling inspection plans were generated by running an optimization model for different possible acceptance numbers. While, in the second step: Multi-Attribute Decision...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such as...

abstract: performance evaluation models of information and communication technology (ict) sectors have been already considered with many perspectives of ict management. since ict has two distinct aspects of usefulness and harmfulness for the environment, therefore, this research with regard to the new dimension named environment, is going to present a new performance evaluation model with the a...

Rivers are important as the main source of supply for drinking, agriculture and industry.However, drinking water quality in terms of qualitative parameters, is the most important variable. Studias and predicting  changes in quality parameters along a river, are one of the goals of water resources planners and managers. In this regard, many water quality models in order to maintain better water ...

background: nowadays, many organizations such as hospitals have realized that utilization of quality management models and systems is the best way for them to compete, survive and develop. therefore, 5s (sorting, straightening, systematic cleaning, standardizing, and sustaining) model was implemented in three units of imam reza hospital (kermanshah, iran) including medical records, nutrition, a...
