background and objectives: hospitals usually generate large amounts of hazardous waste. if not managed properly, hospital waste can pose threats to public safety and damage the environment. waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. this study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

the method of entropy production minimization for finding energy efficient paths of operation of process equipment is first presented using an instructive example with optimal control theory. with refer-ence to the earlier investigations, the researchers present some design rules that relate to the designs’ en-tropy production. minimum entropy production is not obtained in special cases, not ge...

This paper presents a multi-objective Particle Swarm Optimization (PSO) algorithm for worker assignment and mixed-model assembly line balancing problem when task times depend on the worker’s skill level. The objectives of this model are minimization of the number of stations (equivalent to the maximization of the weighted line efficiency), minimization of the weighted smoothness index and minim...

randomization is an essential component of sound clinical trials which prevents selection biases and helps in blinding the allocations. randomization is a process by which subsequent subjects enrolled into trial groups only by chance which is essentially eliminates selection biases. a serious consequence of randomization is severe imbalance among treatment groups with respect to some prognostic...

Design of blast resistant structures is an important subject in structural engineering, attracting the attention of governments, researchers, and engineers. Thus, given the benefits of optimization in engineering, development and assessment of optimization methods for optimum design of structures against blast is of great importance. In this research, multi-objective optimization of steel momen...
