Question.1. “We have entered the age of technology; henceforth everything will be knowledge based.” Discuss the above in the context of increasing use of technology-based resources for achieving tasks.

Answer:The Information Age (also known as the Computer Age, Digital Age, or New Media Age) is a period in human history characterized by the shift from traditional industry that the Industrial Revolution brought through industrialization, to an economy based on information computerization. The onset of the Information Age is associated with the Digital Revolution, just as the Industrial Revolution marked the onset of the Industrial Age.

During the information age, the phenomenon is that the digital industry creates a knowledge-based society surrounded by a high-tech global




Question.2. Over the years, many variations on classical Delphi have been forwarded. Briefly discuss these variants.

Answer:: As Delphi has spread, many variants of the process have emerged out of the conventional procedure. Each variant aimed at improving the procedure in order to respond to needs and critiques. The attempts to refine the Del phi procedure were undertaken by Olaf Helmer (1966b) himself, the originator of Delphi. Since then many other versions have been suggested to reflect and solve different problems. Variants that developed a practical approach to Delphi as a means to facilitate group judgment formulation and



Question.3. Capacity will be modified in response to demand. Demand will be modified in response to capacity. Which of these two statements is correct? Why?

Answer:When an organization has a clear grasp of its capacity constraints and an understanding of demand patterns. It is in a good position to develop strategies for matching supply and demand.

There are two general approaches for accomplishing demand and capacity.

·         The first is to smooth the demand fluctuations themselves by shifting demand to match existing supply.



Question.4. What are the different criteria for scheduling jobshop production system? Give their justification also.

Answer:Job shop scheduling (or job-shop problem) is an optimization problem in computer science and operations research in which ideal jobs are assigned to resources at particular times. The most basic version is as follows:

We are given n jobs J1, J2, ...,Jn of varying sizes, which need to be scheduled on m identical machines, while trying to minimize the makespan. The makespan is the total length of the schedule (that is, when all the jobs have finished processing). Nowadays, the problem is presented as an online problem (dynamic scheduling), that is, each job is presented, and the online algorithm needs to make a decision about that job before the next job is presented.

This problem is one of the best known online problems, and was the first problem for which competitive analysis was presented, by Graham in




Question.5. Inventory of material provides operational flexibility. But, many flexible operational systems need little inventory. Explain this seeming contradiction.

Answer:Companies today must be fast and nimble enough to react quickly to changes in customer demand and do it with little inventory. Gone are the days when manufacturers could stockpile large quantities of raw materials, load up the shop floor with work-in-process and pack warehouses with finished goods. The old ways caused erratic and long lead times, high costs and required too much cash for working capital.
