This can be known as system-oriented reliability planning (SORP). However, there can exist some customers that are not satisfied by their reliability determined by ado...

in many real world assembly line systems which the work-piece is of large size more than one worker work on the same work-piece in each station. this type of assembly line is called multi-manned assembly line (mal). in the classical multi-manned assembly line balancing problem (malbp) the objective is to minimize the manpower needed to manufacture one product unit. apart from the manpower, othe...

Requirements engineering (RE) is an essential initial stage in software engineering. The RE process begins with the elicitation stage. This collects all user requirements that must be fulfilled by system which will developed. A goal-oriented approach effective used to automate process. development of input document standards one important issues has not been widely studied. Therefore, this stud...

A large scaled network may consist of hundreds of disparate and autonomous databases.

That is, in most cases, only a subset of databases is required for the users' requests. As th...
