In this paper, we address the backlog sequencing problem in a flow-shop controlled by a CON\VIP production control system with the objective to minimise the make span We characterise the problem and analyse its similarities and differences with the permutation flow-shop problem A comparison of...

This paper presents mathematics of the so-called fuzzy greedy evaluation concept which can be integrated into approaches for hard combinatorial optimization problems. The proposed method evaluates objects in a way that combines fuzzy reasoning with a greedy mechanism, thereby exploiting a fuzzy...

This article presents mathematics of a generic polynomial-time heuristic which can be integrated into approaches for hard combinatorial optimization problems. The proposed method evaluates objects in a way that combines fuzzy reasoning with a greedy mechanism, thereby exploiting a fuzzy solution...

In this paper, a novel scheduling model for a job-shop environment under the effect of sequencing was proposed. The decision variables from a manufacturing company, which consists of two designed parallel machines with zero buffer capacity, each with 10 jobs were investigated. Four scheduling...

In small-item large lot production, a single person had only single processing to do. A recent tendency of the production system is the multi-item small lot production. In this type of production system, one work person needs skills that are adaptable to multi-item articles. As the single work...

We consider the scheduling problem of minimizing the average weighted completion time on identical parallel machines when jobs are arriving over time. For both the preemptive and the nonpreemptive setting, we show that straightforward extensions of Smith's ratio rule yield smaller competitive...
