Multiobjective Programming,lt is an optimal solution (or multiple optima, in case of dual degeneracy). However, the concept of optimality applies only in case of a single objective. If we state that something is “the best” or optimal, we always have an objective in mind: the fastest car, the most comfortable vehicle, the auto

Machine Scheduling, doctor treating patients the doctor is the processor and the patients represent the tasks, in the case of a tax auditor the auditor is the processor (or the “machine”), while the individual cases are the tasks to be processed.

Multicriteria Decision Making,t to the scenario in decision analysis, the outcomes are again deterministic. In other words, if we were to, say, change the composition of a soft drink we manufacture or change the controls on a television, we do not just deal with profit as a result of this decision, but face changing customer acc

Stochastic Processes and Markov Chains,ocesses, events occur over time. Time can be dealt with either in continuous fashion, or in discrete fashion. In the continuous case, we may look at the speed of an automobile at any given point in time or at the inventory level of a product in a supermarket at any time. In the discrete case, speed
