چکیده
Nicholas G. ODREY Professor, Department of Industrial & Manufacturing Systems Engineering, Lehigh University, Bethlehem, PA 18015, USA. ABSTRACT A real-time scheduling and control methodology in dioid algebra that allows repeated production of parts over the planning horizon of a flow-shop in the presence of disturbances is proposed in this paper. The behavior of a manufacturing system as an discrete-event dynamic system can be completely characterized by the knowledge of starting and ending times of its activities. Dioid algebra can be used to represent discrete event dynamic systems where relationships between the starting times of the activities require maximum and addition operators and are linear in the sense of dioid algebra. To use dioid algebra in a real-time scheduling and control methodology, conflict resolution and optimization are introduced into dioid algebra with this study.

Uncertainty plays a significant role in modeling and optimization of real world systems. Among uncertain approaches, fuzziness describes impreciseness while for ambiguity another definition is required. Vagueness is a probabilistic model of uncertainty being helpful to include ambiguity into modeling different processes especially in industrial systems. In this paper, a vague set based on dista...

While a great portion of the scheduling literature focuses on time-based criteria, the most important goal of management is maximizing the profitability of the firm. In this paper, the net preset value criterion is studied taking account of linear time-dependent cash flows in single machine and flow shop scheduling problems. First, a heuristic method is presented for the single machine scheduli...

متن کاملA Hybrid Approach for Fuzzy Just-In-Time Flow Shop Scheduling with Limited Buffers and Deteriorating Jobs
This paper investigates the problem of just-in-time permutation flow shop scheduling with limited buffers and linear job deterioration in an uncertain environment. The fuzzy set theory is applied to describe this situation. A novel mixed-integer nonlinear program is presented to minimize the weighted sum of fuzzy earliness and tardiness penalties. Due to the computational complexities, the prop...
