Efficient Drilling Sequence Optimization Using Heuristic Priority Functions

SPE Journal, 2021
SummaryDrilling sequence optimization is a common challenge faced in the oil and gas industry, and yet it cannot be solved efficiently by existing optimization methods due to its unique features and constraints. For many fields, the drilling queue is currently designed manually based on engineering heuristics.

Priority Heuristic in MDRTDBS

International Journal of Sensors, Wireless Communications and Control, 2020
Background: Mobile distributed real time database is an emerging field of research. Transaction execute in these system should commit before elapsing the deadline. Assigning priority to arrived and executing transaction is the main function of transaction scheduler.

Fuzzy priority heuristics for project scheduling

Fuzzy Sets and Systems, 1996
Abstract This paper presents a generalization of the known priority heuristic method for solving resource-constrained project scheduling problems (RCPS) with uncertain time parameters. The generalization consists of handling fuzzy time parameters instead of crisp ones.

Evolving priority scheduling heuristics with genetic programming

Applied Soft Computing, 2012
This paper investigates the use of genetic programming in automated synthesis of scheduling heuristics for an arbitrary performance measure. Genetic programming is used to evolve the priority function, which determines the priority values of certain system elements (jobs, machines). The priority function is used within an appropriate meta-algorithm for
