  • Planning and implementing a manufacturing control system in a job shop environment

    Creator:
    Maplestone, Robert N.
    Abstract:
    This thesis is intended to provide the management of small to medium sized job shop companies with a written plan to implement a formal computerized manufacturing planning and control system. The research stemmed from a case study performed at a typical job shop where growth of production activities was complicating...

  • Simulation-based design evaluation of automated storage/retrieval systems

    Creator:
    Shroff, Raj N.
    Abstract:
    Automated storage and Retrieval (AS/R) systems have had a significant impact on storage and retrieval of finished goods, work-in-process, and raw materials and supplies. A microcomputer-based simulation model was developed to evaluate different unit load AS/R systems serving multiple input sources and output destinations. The simulation results were statistically analyzed...

  • Design and implementation of a production scheduling system for continuous manufacturing environment

    Creator:
    Rai, Nivruti
    Abstract:
    Scheduling a continuous manufacturing flow shop environment with several machines, stochastic arrival of demands, different product requirements and limited resources is a complex task. This research develops a methodology for scheduling products in glass fiber industry. The system consists of two components. An optimizing linear program determines the optimal solution...

  • An experimental investigation and comparative evaluation of scheduling strategies for a dynamic job shop in a tool sharing environment

    Creator:
    Xu, Zhongkai
    Abstract:
    Good tool management and job operating strategies will result in reduction in tool inventory and associated costs. Very little empirical research has been conducted on a Flexible Manufacturing System (FMS) as a whole in relation to its performances with tool movement approach, specifically in a dynamic job shop in a...

  • A methodology for real-time scheduling of jobs with splitting on unrelated parallel machines

    Creator:
    Subur, Fenny
    Abstract:
    Unrelated parallel machines are machines that perform the same function but have different capacity or capability. Thus, the processing time of each job would be different on machines of different types. The scheduling environment considered is dynamic in both job release time and machine availability. Additionally, each job considered can...

  • Two-stage flexible flow shop scheduling with blocking constraint and batching machines

    Creator:
    Panahi, Hadi
    Abstract:
    In this dissertation, a two stage flexible flow shop scheduling problem is studied, where in stage 1, there are identical batch processors (burnout ovens) and in stage 2, there are identical discrete processors (furnaces). Batch processors perform a pre-heating process on a batch of jobs at a time and discrete...

  • Bi-criteria group scheduling with sequence-dependent setup time in a flow shop

    Creator:
    Lu, Dongchen
    Abstract:
    Cellular manufacturing, which is also referred to as group technology among researchers, has primarily been used as a means to increase productivity, efficiency and flexibility. Under group technology, similar jobs, which have similar shape, material, and processing operations are assigned to the same group. Moreover, dissimilar machines are assigned to...

  • A methodology for scheduling jobs in a flexible flowshop with sequence dependent setup times and machine skipping

    Creator:
    Pandya, Vaibhav
    Abstract:
    A flexible flowshop, comprised of one or more stages having unrelated parallel machines, is investigated in this research. Unrelated parallel machines can perform the same function but have different capacity or capability. Since this problem is motivated by industry research, dynamic job release times and dynamic machine availability times have...

  • Linking equations for the analysis of a serial automated workstation system

    Creator:
    Nagarajan, Raghavendran D.
    Abstract:
    In this research, an analytical model for analyzing a production line consisting of a series of automated workstations with infinite buffers is developed. Automated workstations are assumed to have deterministic processing times, and independent exponentially distributed operating time between failures and repair times. The analytical model starts with existing results...

  • Bi-criteria group scheduling with learning in hybrid flow shops

    Creator:
    Bozorgirad, Mir Abbas
    Abstract:
    In this research, a bi-criteria group scheduling problem is investigated in hybrid flow shop (HFS) environments, where the parallel machines in each stage are unrelated, meaning not identical. The objective of the problem is to minimize a linear combination of the total weighted completion times as a means of complying...
