Metaheuristic Approach for Simultaneous Delivery and
Pick-Up Problem of Banking Industry
-- S P Anbuudayasankar, K Ganesh and K Mohandas
Commercial banks are trying to change customer preference from doing banking transactions
through branch channels to electronic channels. Consequently, an increasing number of Automated
Teller Machines (ATMs) are being setup. This paper deals with Vehicle Routing Problem (VRP)
arising from an ATM routing with Simultaneous Delivery and Pick-up (SDP), a real-world
routing-scheduling problem. The major goal of this research is to develop an efficient heuristic that solves the
ATM routing problem, VRPSDP and produces the optimal solution with the objective of minimizing
the distance travelled in a reasonable computation time. Simulated Annealing is developed as
the solution methodology and compared with benchmark data-sets. The results are encouraging in
terms of solution quality and computation time.

Web Integrated Decision Support System for Machine Scheduling and Inventory Management
-- L Sivarama Krishna, G Ranga Janardhan and C S P Rao
Scheduling and inventory management are two important decision-making processes in
any manufacturing industry. Scheduling is done with many objectives, like, aiming to minimize
the makespan or minimizing the number of tardy jobs. Inventory management refers to the process
of managing stocks of finished products, semi-finished products and raw materials by a firm so as
to minimize the total inventory cost. Generally, these processes are treated as two different aspects
in the decision-making process. This paper deals with the development of a Decision Support
System (DSS) that integrates machine scheduling with inventory management for a
multi-product manufacturing industry. The system was developed in three phases. The first phase involves
the development of a scheduling system with makespan minimization as the primary objective.
The second phase involves the development of the inventory management system and integrating it
with the scheduling system. The third phase involves making the system web enabled, so that it
provides the flexibility of distributed decision making to the decision makers.

A Genetic Algorithm Based Optimization Technique for Scheduling Identical Machines
in Flexible Manufacturing Systems
-- Vijay Kumar M, A N N Murthy and K Chandrashekhara
The designers and manufacturers of Flexible Manufacturing Systems (FMS) strive to
ensure maximum flexibility in terms of design, planning, scheduling and control in the system. In
practice, it is hard to accommodate frequent variations in the part designs of incoming jobs during
the implementation of such manufacturing systems. The variation in job design can be
efficiently overcome by scheduling a variety of incoming parts into the system. In this paper, an
appropriate heuristic-based scheduling mechanism is designed and developed to generate a nearer to
optimum schedule, using Genetic Algorithm (GA). GA is used in solving optimization problems in view of
its characteristic of high efficiency and being fit for practical application. A GA based on machine
code is developed and presented for minimizing the makespan in an identical machine
scheduling problem. The GA developed is efficient and advantageous for scheduling scale identical
parallel machine manufacturing systems for minimizing the makespan, which is demonstrated
through numerical solutions. The quality of its solution is better suited over heuristic and Simulated
Annealing (SA) algorithms.

Interactive Decision Making in Prioritized Unbalanced Transportation Problems
-- R K Dwivedi, N N Mehta and O P Dubey
In transportation problems faced by a government or a business firm, the problems are not
balanced, i.e., supply is less than demand or vice-versa due to paucity of funds. Sometimes, it becomes
necessary to transport a certain percentage of commodities (demand) irrespective of the transportation
cost. Almost all decision makers dealing with transport management are interested in minimization
of total transportation cost and transportation time to each destination along with the fulfillment
of priorities (goals). The present paper deals (on a small scale) with a prioritized unbalanced
problem regarding transportation of coal from four production points (collieries) to three places under
Bharat Coking Coal Ltd. (BCCL) in the Kuzu/Charhi area.
