Job Sequencing & WIP level determination in a cyclic CONWIP Flowshop with Blocking
… of the line by determining an appropriate job sequence. This research assumes a 'permutational' scheduling policy and proposes an iterative approach to find the best sequence. The approach utilizes a controlled enumerative approach called the Fast Insertion Heuristic (FIH) coupled with a …

Job Sequencing and Tool Switching Problems with a Generalisation to Non-Identical Parallel Machines
… the manufacturing process since the 1960s. The job sequencing and tool switching problem is an NP-hard combinatorial optimization that has first been introduced in the context of flexible manufacturing systems in the late 1980s. Since then, production systems have undisputedly changed and …

A methodology that integrates the scheduling of job sequencing and AGV dispatching in a FMS
… to develop a scheduling methodology to integrate job sequencing and Automatic Guided Vehicle System dispatching within a FMS environment. To develop the new scheduling methodology, the currently used AGVS controller decision set was examined and expanded. The expanded decision set gives the AGVS …

A General Framework for Robot Programming Using a Matrix-based Supervisory Controller
… to determine its feasibility in terms of job sequencing and resource allocation.An overall robot programming framework that bridges the high-level planning and that of the physical execution has been proposed and developed.

A design methodology for operational control elements for automatic guided vehicle based material handling systems
… vehicle routing, unit load size selection, job sequencing, shop loading, queue constraints, and capacity constraints due to vehicles and machines. A job in the shop is considered to consist of one or more parts grouped in portable unit load sizes. Therefore, it is unit loads rather than jobs …

Stochastic Cellular Manufacturing System Design and Control
… issues such as cell formation, cell loading and job scheduling. However, majority of literature lacks consideration of uncertainty in the problem definition phase, thus methodology. In this dissertation, the impact of uncertainty of demand, processing times and capacity requirements on a cellular …

Improving Manufacturing Systems Using Integrated Discrete Event Simulation and Evolutionary Algorithms
… stated aim, research here has investigated the job sequence and buffer management problem in high variety/low volume manufacturing environment, where lead time and total inventory holding cost are used as operational performance measures. The research here has introduced a novel approach through …

Enhanced Formulations for Minimax and Discrete Optimization Problems with Applications to Scheduling and Routing
… for the notoriously challenging class of job-shop scheduling problems with the objective of minimizing the maximum completion time (i.e., minimizing the makespan). In particular, we develop an RLT-enhanced continuous nonconvex model for the job-shop problem based on a quadratic formulation …

Novel Approaches for Some Stochastic and Deterministic Scheduling Problems
… of problem parameters (in particular, due to job processing times), and batching of jobs for processing on capacitated machines. Our approach to address the uncertainty issue regards the indeterminate parameters as random variables, and explicitly considers the resulting variability of a …
