This paper examines a single machine sequencing problem with a quadratic cost function of completion times. A new type of precedence relation is constructed that determines the ordering between adjacent jobs. Each pair of jobs has a critical start time, after which the precedence relation...

This paper describes a new heuristic, the Revised Hillier procedure, for solving the facilities layout problem. It incorporates the effective features of the well-known Hillier procedure in combination with 3-way and 4-way exchanges to extend the neighborhood over which the search for a solution...

This paper surveys work done to date on the problem of laying out the facilities of some system in terms of specifying which activities are to be adjacent. Each pair of facilities has a closeness rating which represents the desirability that they are located adjacently. Ratings are usually...

Estimating the annual production cost is a crucial component in long range capacity planning for electric utilities. Traditional simulation-based methods are quite expensive in terms of computer resources (space and time), while simpler mathematical programming-based models generally assume a...
