Production scheduling in a foundry machine shop
The scheduling of production in job shops is generally accomplished in four stages; aggregate planning, machine loading, sequencing and detailed scheduling. In industrial job shops, the number of jobs and machines makes detailed scheduling a particularly complicated and unwieldy task. When faced …

Production scheduling in a campaign based flexible flow shop
… there is increased pressure to reduce the production cost and therefore good scheduling approaches become more important. The aim of this research is to improve the production scheduling process at a pharmaceutical company. The manufacturing plant operates in a campaign mode. Products that …

improving contact lens manufacturing through cost modeling and batch production scheduling optimization
J&J Vision Care (JJVC) uses production scheduling methods that are not fully optimized, causing over-production of certain SKUs, and reducing capacity for other SKUs on backorder. This makes planning a weekly run-schedule for each line difficult. It is also difficult to understand where to invest …

Multiple-part-type production scheduling for high volume manufacturing (time-based approach)
An effective production scheduling strategy would lead to efficient production line performance as well as increased profit. However, there is no fixed or generalized solution. In this thesis, Nonlinear Programming and time-based Control Point Policy were applied in sequence to solve the production …

Multiple-part-type production scheduling for high volume manufacturing (token-based approach)
Multiple-part-type production scheduling is a common industrial problem with no generalized solution. In this thesis, a systematic approach is presented to aid in the mentioned production decision making in an actual factory. This strategy involves first generating production targets by …

Production scheduling in a make-to-order job shop under job arrival uncertainty
We consider job release control to improve the due date performance in a make-to-order job shop with fluctuating job arrival and fixed due dates. The basic idea is to delay the release of non-urgent jobs and control the work in process (WIP) before the bottleneck so as to control the lead time of …

Modeling the tradeoff between inventory and capacity to optimize return on assets in production scheduling
… peak seasons, while the other is to increase the production capacity so that the companies can react to the changing demand more quickly. However, either alternative comes at a significant cost. This paper examines the optimal mix of production capacity and inventory for a company to meet …

Multiple-part-type systems in high volume manufacturing : Kanban System design for automatic production scheduling
A Kanban Production System is designed to help a factory line meet fluctuating demands for multiple part types. Based on the parameter settings of the Control-Point Policy, the optimum Kanban levels are obtained. The simulation software Simul8 was used to model the factory line and the Kanban …

A Comparison of Alphanumeric, Direct Manipulation Graphic, and Equivalent Interface Design for a Production Scheduling Task
<p>Scheduling is an essential factor influencing the efficiency of any production system. The effectiveness of the scheduling system depends upon the interaction of the human and machine. Thus, to effectively design the interface between the human and the machine, the human factors professional …
