    Heuristic Approach for n-Jobs, 3-Machines Flow Shop Scheduling Problem, Processing Time Associated With Probabilities Involving Transportation Time, Break-Down Interval, Weightage of Jobs and Job Block Criteria
    (Mathematical Theory and Modeling Vol.1, No.1, 2011, 2011) Deepak Gupta; Samir Sharma; Seema Sharma
    This paper deals with a new simple heuristic algorithm for n jobs, 3 machines flow shop scheduling problem in which processing times are associated with their corresponding probabilities involving transportation time, break down interval and job block criteria. Further jobs are attached with weights to indicate their relative importance. A heuristic approach method to find optimal or near optimal sequence minimizing the total elapsed time whenever mean weighted production flow time is taken into consideration. The proposed method is very easy to understand and also provide an important tool for decision makers. A numerical illustration is also given to clarify the algorithm

    On Linkage of Parallel Biserial Servers Linked with a Common Server to a Three Stage Flowshop Scheduling Model
    (International Journal of Applied Physics and Mathematics, Vol. 2, No. 3,, 2012) Deepak Gupta; Sameer Sharma; Seema Sharma
    The present paper deals with the linkage between a queue network in which a common service server is linked in series with each of two parallel biserial servers and a three stage flowshop scheduling system. The objective of this paper is of two folds, on one hand it finds mean queue length and the total waiting time of jobs and on other hand it minimizes the total elapsed time. The proposed model provides an important tool for manufacturing concern, office management, banking service system, computer networks and in administrative setup etc.
