The paper deals with a stochastic multi-product sequencing and lot-sizing problem for a line that produces items in lots. Two types of uncertainties are considered: random lead time induced by machine breakdowns and random yield to take into account part rejects. In addition, sequence dependent setup times are also included. This study focuses on maximizing the probability of producing a requir...

Optimal placement and sizing of DG in distribution network is an optimization problem with continuous and discrete variables. Many researchers have used evolutionary methods for finding the optimal DG placement and sizing. This paper proposes a hybrid algorithm PSO&HBMO for optimal placement and sizing of distributed generation (DG) in radial distribution system to minimize the total power loss...

ABSTRACT: Parallel Assembly Lines with multi-line stations (PALBs) have been widely studied in recent years because PALBs can help improve the efficiency of a production system. However, need buffers has not considered PALBP literature. In this study, for first time literature, it is shown and demonstrated to consider use type line when their cycle times are different. Moreover, buffer sizing p...

In emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS...

This project bestows optimal sizing and placement of FACTS device, which is achieved by the searching method of bacteria foraging algorithm (BFA) with optimal sizing of FACTS device. Static Var Compensator (SVC) is one of the FACTS devices, utilized for progress of voltage profile and loss minimization. The precise strategy of SVC offers the real power loss minimization with increase of voltage...

We demonstrate that Digital Holographic Microscopy can be used for accurate 3D tracking and sizing of a colloidal probe trapped in a diamond anvil cell (DAC). Polystyrene beads were optically trapped in water up to Gigapascal pressures while simultaneously recording in-line holograms at 1 KHz frame rate. Using Lorenz-Mie scattering theory to fit interference patterns, we detected a 10% shrinkin...

abstract This paper presents a simple and robust method of designing the lossy-transmission-line interconnects in a network for multichip modules. This method uses wire-sizing entirely to meet the electrical damping criteria to solve the problems encountered in propagating high-speed signals through unterminated lossy transmission lines on the substrates of multichip modules (MCM). The optimal ...

Software companies exploit data about completed projects to estimate the development effort required for new projects. Software size is one of the most important information used to this end. However, different methods for sizing software exist and companies may require to migrate to a new method at a certain point. In this case, in order to exploit historical data they need to resize the past ...
