Abstract Timetabling problem is known as an NP-hard that centres around finding optimized allocation of subjects onto a finite available number slots and spaces. It perhaps the most challenging issues looked by colleges globe. Every academic institution faces when preparing courses exam plans. There are many restrictions raised while timetable. This paper proposed method based on evolutionary algorithms to solve constrained timetable problem, which helps create theory well lab schedule for...

The main purpose of this research work is to present a reliability analysis two dissimilar parallel unit framework under the presumption that framework's may also fail during preventive maintenance (PM).Only one repair man available with system.It has been assumed he well capable doing every including maintenance.Here in we have failure and times each are correlated.Utilizing regenerative point strategy different attributes obtained which very much helpful system/ designers company...

The aim of this work is to present a reliability and profit analysis two-dissimilar parallel unit system under the assumption that operative cannot fail after post repair inspection replacement there only one facility.Failure times each are assumed be uncorrelated.Using regenerative point technique various characteristics obtained which useful designers industrial managers.Graphical behaviors mean time failure (MTSF) function have also been studied.In paper, some important measures two...

Abstract A dynamic model comprising anisotropic viscoelastic solid with voids along two temperature and three phase lag is used to study the propagation of harmonic waves. The system differential equation made dimensionless by incorporating suitable quantities. Harmonic type plane wave solution assumed determine Christoffel equation. From this five quasi-waves are noticed which vibrate distinct speed in infinite medium under impact void, viscosity. velocity attenuating factors waves computed...

The purpose of this article is to discuss the availability a three unit framework (A, As, B) existing in paper industry with provision inspection one and that can be replaced after inspection. Here work we have considered failure repair time every correlated each other by using regenerating point technique (RPT) find optimal system reliability availability. With help experimental results found values characteristics like busy period person. We also discussed impact these on profit .This...

Background and Aim: With an increase in demands about the reliability of industrial machines following continuous or discrete distribution, important thing to be noticed is that all previous research works where systems had more than one failure, no iteration technique was studied separate failed unit on basis its failure. Therefore, aim our paper analyze real problems cold standby units arranged parallel manner with new concept inspection procedure for detect exact failure being...

Abstract The device named autoclave used in pharma industries has been studied this paper. This study provides the discussion how to obtain reliability testing strategy of two dis-similar parallel units. system is considered be operative condition if at least one out state. A single repair facility available for repairing both kinds failed In addition mechanism, inspection policy also introduced automatic unit. But manual does not require any such supervision facilty. Various essential...

In this paper two identical parallel units have been analyzed by using discrete distribution and regenerative point technique. The for repair time inspection policy detecting the kind of failures (minor or major) are taken as geometric distribution. Various reliability measures system effectiveness such mean to failure, steady state availability busy period both repairman were obtained. Graphs has plotted system, that concluded behaviour profit function which increase along with in rate...

The Vehicle Routing Problem is an optimization problem with number of applications in the transportation field. In this paper, (VRP) uncertainty customer demand considered. Often real world situation, information on each not accurate enough. Here, article we are assuming that demands time period uncertain and considered as fuzzy variables. This kind known NP-hard problem. main purpose to give conceptual practical idea how logic meta heuristic algorithm can be implemented improve vehicle...

In this research, a method based on the Laplace transform and He's variational iteration is utilized for solving (1+1)-Dimensional Schrodinger's equation modeled in different branches of Engineering sciences. The proposed technique Laplace-transform variation iterative method. Some examples are given to describe capability technique.

Over the past few years, there has been increased awareness about importance of protecting environment particularly after global warming came up. The approach proposed here in this paper for reducing fuel consumption is combination clustering algorithms’ ideas with natural optimization techniques, aimed at efficient route vehicles. It uses to group customer locations together that turn allows development more routes. goal study reduce while optimizing travel plans. This a nature-inspired...

In corporate and industries sectors, transportation plays an important role. Vogel Approximation Method (VAM) is a effectual method to find the initial basic feasible solution of problems, but when there tie between highest penalty costs for rows columns, we have choose arbitrary which results may get far from optimal also. this paper, modified steps VAM solution. The proposed revised algorithm (RA-VAM) gives always nearest Three examples are also solved illustrate RA-VAM.

The present paper is an initiative towards analyzing the maintenance process of industrial model using regenerative techniques. With increase in demands to analyze reliability any models following continuous or discrete distribution, major concern be considered inspect possibility and level failure proceeding failed unit for further repairing process. system consists two parallel units passive standby redundancy with different mechanism. proposed analytical methodology made it possible...

The present paper had analyzed the reliability of a real-life working mechanism having two units arranged in parallel form and following cold standby redundancy technique. repair includes inspection/repair policy for normal major service according to nature failure. Initially One unit is operative mode, while other passive mode. new notion repairman has aspects: checking small failures being able routine failures. Furthermore, inspecting repaired equipment determine if it was effectively...
