    1 Boolean Function Approach for Reliability of Milk Power Plant

    Author: Navyata, Neelam Sharma and Surbhi Gupta,(Pages: 51-59)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:In this Paper the author has worked on Milk Power Plant.The objective of this paper is to find the reliability of Milk Power Plant using Boolean function technique the failure and repair rates of the subsystem. The whole system consists of six parts. First part of the system is a material input (Raw milk).Second part of the system is Energy input (Fuel). Third part of the system is a Processing Plant. Fourth part of the system is Plant services. Fifth part of the system is Milk Packing. The Six part of the system is Delivery to customer. These six parts are connected in series. The author has used the Boolean functions to evaluate the ability of the considered system. Reliability of the each component that has been obtained in three different cases is denoted by R, if failure rates follow Weibull time distribution and the failure follow exponential time distribution. Keyword: Boolean function, Weibull time distribution, Exponential time distribution.Download:

    1 Operational Readiness of Steam Power Plant System Using Neural Network Approach

    Author: Ekata, Ritu Gupta and C. M. Batra,(Pages: 61-73)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:This paper deals with reliability and profit analysis of a steam power plant system. The system is divided into four main subsystems. A multilayered neural network model is used in order to improve the maintenance of the steam power plant system. The system may fail due to hardware failure. All types of failures and repairs are exponential. System state probabilities and other parameters are developed for the proposed model using neural network approach. Numerical examples are included to demonstrate the results. The iterations are repeated till the convergence in the error tends up to 0.0001 precision Keyword: Neural Network, neural weights, profit function, reliability, Stochastic ProcessDownload:

    1 Modelling And Availability Analysis Using Single Unit Power Cable In Metro Railways

    Author: Ranu Pandey, Ajay Kumar Gupta and Bhupender Parashar,(Pages: 75-86)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:The current study of the metro network system discusses the reliability modelling and system availability of this failure resistant network through power cables. The function of the cables is used for supplying power to substations from each station. The study is concentrated taking single unit cable of 33 KV with no standby unit. The inspection is carried out at each failure to access the systems repairable or irreparable condition. The calculations to measure Mean Time to System Failure (MTSF) and Availability Analysis (AA) are completed using “Semi-Markov Processes” and “Regenerative Point Technique”. The results are represented graphically Keyword: Availability Analysis, Modelling Analysis, Power Cables, Profit Analysis, Regenerative Point Technique, Semi-Markov Processes, System EffectivenessDownload:

    1 The Survey of Packet Loss Differentiation Techniques in TCP

    Author: Sejal Haveliwala and Hemal Shah,(Pages: 87-104)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:In wireless network packet loss occurs due to congestion, Wireless channel error and link failure. Here Transmission control protocol cannot respond the packet loss properly. It degrades its performance by presuming the loss due to congestion. So it has become important to find the reasons behind these losses for improvement in TCP's performance. Many researchers have worked in this area and evaluated algorithms which differentiate the cause of packet losses. This paper surveys about various techniques mitigate Packet Loss Differentiation as well as focuses on certain open areas for future research. Most of the surveyed reveals that researchers have worked for the congestion loss only, handful schemes cannot identify the link failure loss. The TCP's performance can be improved with proper loss recovery technique, suitable congestion avoidance scheme and there can be mechanism to switch between suitable Loss Recovery Algorithm (LRA) or congestion avoidance scheme automatically as per identified loss.

    1 Order level inventory model with Weibull distribution Deterioration and Shortages under Trade Credit

    Author: S. K. Shon and Satyarth Prakash Maurya ,(Pages: 105-116)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:In this paper an order level inventory model for deteriorating items has been developed. Deteriorating rate is taken as two parameter Weibull distribution. Holding cost is taken as time dependent. We consider the situation that the buyer is asked to pay the entire amount of contract to the vendor in advanced before the delivery of goods. Moreover, discount is considered by the retailer if the entire purchasing cost is paid by the buyer in advanced. EOQ models are developed with full numerical illustrations, convexity and sensitivity analysis for decaying product under different conditions.

    1 An EPQ model for deteriorating items with exponential demand under inflation

    Author: S. K. Shon, Satyam Kumar Sharma,(Pages: 117-125)
    Email: itmsc@aacsjournals.com          DOI: N/A

    Abstract:In this paper a production model for deteriorating items with exponential demand under inflation has been developed. Production rate is taken as demand dependent. The deterioration rate is taken as a two-parameter Weibull distribution. The main aim of the study is to minimize the total cost. Results are illustrated with numerical example and shown with graphically. Also the sensitivity analysis of various parameters is discussed.
