Multi-Objective Job Shop Scheduling Using a Lexicographic Procedure
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 1
Abstract
In this paper, a multi-objective job shop scheduling model using Goal Programming (GP) lexicographic procedure is formulated based on makespan, total tardiness and total earliness criteria. The objectives of minimizing both the makespan and total earliness are generally considered inconsistent or conflicting objectives. Conversely, the objectives of minimizing the makespan and total tardiness are usually consistent objectives. However, the objectives of minimizing total earliness and total tardiness are typicaly two independent objectives. The effect of priority ordering and objective deviation are discussed through thirty 3x3 and four 10x10 problems.
