Production scheduling is one of the very important problems that industry and production are confronted with it. Production scheduling is often planned in the industrial environments while productivity in production can improve significantly the expansion of simultaneous optimization of the scheduling plan. Production scheduling and production are two areas that have attracted much attention in...

although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. but, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. this paper considers the problem of scheduling no-idle hybrid flow shops. a mixed integer linear programming model is first developed to mathematically form...

Operating room surgery scheduling deals with determining operation start times of surgeries on hand and allocating the required resources to the scheduled surgeries, considering several constraints to ensure a complete surgery flow, the resource availability, and specialties and qualifications of human resources. This task plays a crucial role in providing timely treatments for the patients whi...

job shop scheduling problem has significant importance in many researchingfields such as production management and programming and also combinedoptimizing. job shop scheduling problem includes two sub-problems: machineassignment and sequence operation performing. in this paper combination ofparticle swarm optimization algorithm (pso) and gravitational search algorithm(gsa) have been presented f...

Scheduling elective surgeries is a dynamic, sequential decision-making 1 process that must balance the costs of deferring waiting cases and blocking higher2 priority cases. Although other surgery scheduling problems have received extensive 3 treatment in the literature, this paper presents the first single-day scheduling problem 4 formulation to capture this aspect of the scheduling process whi...

Patients need to undergo several checkups, tests, surgery and treatments according to their illness. This paper describes the challenges of patient scheduling and patient scheduling techniques. An efficient scheduling technique is needed to minimize the waiting time of patients and to improve the resource utilization. The patient treatment processes are not completely decided at the beginning o...

in this paper a new problem of three stage disassembly-assembly scheduling is introduced and reviewed. this problem, which was arisen from the aviation industry characteristics, is a generalization of the two stage assembly scheduling problem. products (helicopters) in the aviation industry return to assembler for annual overhaul repair services. in the first stage helicopters are disassembled ...

 This paper considers a bi-objective scheduling problem in a flexible manufacturing cell (FMC) which minimizes the maximum completion time (i.e., makespan) and maximum tardiness simultaneously. A new mathematical model is considered to reflect all aspect of the manufacturing cell. This type of scheduling problem is known to be NP-hard. To cope with the complexity of such a hard problem, a genet...

Abstract One of the critical issues in healthcare management is operating room (OR) scheduling problem. Solutions to this problem consider surgery durations and allocate elective surgeries OR sessions order create surgical lists high quality. Determining quality a list key undertaking within focus research. Currently, probability- and/or expectation-based measures are used instead statistical d...
