Evolution of Internet


 
 
 
Mid 1960  :   Papers on “Packet Switching” emerge.

End 1969s:     Advanced Research Projects Agency
                        
                         Network ( ARPA) sponsors the     
                         
                          development of a ARPANET. (A new
                        
                           packet switching network)

1974:               The TCP/IP protocols and model     
 
                            proposed by Cerf/Kahn.

1980:   Introduction of IPv4
1983:   Adoption of TCP/IP by ARPANET
 
1984:   NSF funds a TCP/IP based backbone

                     network,NSFNET.
 
 
1995:                       Internet is completely commercial.

Inter-Organizational Value Chain

The value chain of   a company is part of over all value chain. The over all competitive advantage of an organization is not just dependent on the quality and efficiency of the company and quality of products but also upon the that of its suppliers and wholesalers and retailers it may use. The analysis of overall supply chain is called the value system. Different parts of the value chain 1.  Supplier     2.  Firm       3.   Channel 4 .   Buyer

Big-M Method and Two-Phase Method

Big-M Method The Big-M method of handling instances with artificial  variables is the “commonsense approach”. Essentially, the notion is to make the artificial variables, through their coefficients in the objective function, so costly or unprofitable that any feasible solution to the real problem would be preferred, unless the original instance possessed no feasible solutions at all. But this means that we need to assign, in the objective function, coefficients to the artificial variables that are either very small (maximization problem) or very large (minimization problem); whatever this value,let us call it Big M . In fact, this notion is an old trick in optimization in general; we  simply associate a penalty value with variables that we do not want to be part of an ultimate solution(unless such an outcome is unavoidable). Indeed, the penalty is so costly that unless any of the  respective variables' inclusion is warranted algorithmically, such variables will never be p
