Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...

Meta-heuristic algorithms are well-known optimization methods, for solving real-world problems. Harmony search (HS) is a recognized meta-heuristic algorithm with an efficient exploration process. But the HS has slow convergence rate, which causes to have weak exploitation process in finding global optima. Different variants of introduced literature enhance and fix its problems, but most cases, ...

In this study an efficient meta-heuristic is proposed for layout optimization of truss structures by combining cellular automata (CA) and firefly algorithm (FA). In the proposed meta-heuristic, called here as cellular automata firefly algorithm (CAFA), a new equation is presented for position updating of fireflies based on the concept of CA. Two benchmark examples of truss structures are presen...

This paper presents two meta-heuristic algorithms to solve an extended portfolio selection model. The extended model is based on the Markowitz's Model, aiming to minimize investment risk in a specified level of return. In order to get the Markowitz model close to the real conditions, different constraints were embedded on the model which resulted in a discrete and non-convex solution space. ...

In this study, to enhance the optimization process, especially in the structural engineering field two well-known algorithms are merged together in order to achieve an improved hybrid algorithm. These two algorithms are Teaching-Learning Based Optimization (TLBO) and Harmony Search (HS) which have been used by most researchers in varied fields of science. The hybridized algorithm is called A Di...

In the field of medical research, prediction, as well diagnosis thyroid disease, is a major cause that challenging onset axiom. metabolism regulation, hormone secretions play significant role. Two frequent diseases are hypothyroidism and hyperthyroidism release hormones like thyroid, which regulate body’s rate. For analytics, approach data cleansing utilized to analyze enough primitive data, de...
